The Version 6.0 global average lower tropospheric temperature (LT) anomaly for November, 2019 was +0.55 deg. C, up from the October value of +0.46 deg. C.
The linear warming trend since January, 1979 remains at +0.13 C/decade (+0.11 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).

Probably from 2016 El Nino LMAO
figures, a smug comment to begin the discussion (lmao)…
No warming in 3 years!
Ummm but we had an El Nino three years ago. We are neutral now and still seeing record temperatures for a phase like this. Why is it dannyers like to muddy the water with disinformation? I know, they have no option, because the facts don’t match their narrative.
No warming = this year didn’t break the record.
I was born at 315 ppm CO2 (1957). The earth hadn’t seen a record warm year since 1942. It hadn’t seen a record cold year since 1904. I was 23 (1980) before I saw a record warm year. Then I saw another one the next year. Since then I have seen a dozen more. A total of 14 in the last 40 years. The odds a year setting a record now would be 1 in 140 if the Earth were not warming. But they are more like 1 in 3 now.
As for record cold years, not one since 1904.
Record years based on NOAA dataset.
Yeah, this year will barely make top two. “Normal” is gone, there is no new normal. Next El Nino will see an even sharper, taller spike accelerating us further out of the Holocene. Pity, I was just starting to enjoy it.
Did you know that South Carolina is the only US-state measured a record heat in this century? 24 states still hold their record of the 30’s.

http://mathworld.wolfram.com/Outlier.html
Kreg, please stop trolling.
The warming is from the decreased amount of ice in the Arctic reflecting less than normal heat, a significant positive feedback that will take a while to wear off. Eventually it will, as the primary source of the past 100 years’ warming is a lower number of clouds, which have steadily increased as of late.
Forgive an ignorant question but what is the mechanism making albedo play a significant role during the polar night? Also it looks like the arctic anomaly is actually down from previous month?
Even during polar night the downward longwave radiation never gets lower than around 200 W/m^2. Look at figure S4 in the link:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5559487/bin/41598_2017_8545_MOESM1_ESM.pdf
Hmm. IIRC I read somewhere that ice and snow behaves more or less like a black body for longwave radiation, Don’t remember the source, though.
Totte, I think the heating effect from albedo is culumulative over a span of a decade or more, as the oceans store most of the earth’s heat, so the fact of solar night in the arctic during the winter will not negate the cumulative effect of the past decade’s lowered albedo.
Well Salvatore would say the warming was due to the increased solar activity.
Hang on, that’s not right…… oh no increased solar activity – well: that means cooling will start any time soon right?
Yeah, this 200 year trend will turn around next month:
https://tinyurl.com/y95cmx6t
Right the 2 hundred year graph which clearly shows 3 step changes of warming in its history,1st 1850 to 1880, 2nd 1915 to 1945, and 3rd 1976 to 2006. All 3 of those periods have a similar rate of increase and total rise. The 2 weak cool/pause trends can be clearly seen sitting in between the warm trends. All 3 warm trends were strong warming.
So guess what happens when there are 3 strong warm trends minus the effects of 2 weak cool trends. We get natural warming.
Nir Shaviv and Hans Svensmark actually just did a talk at the EIKE conference in Munich about this. Warming will be in significant reversal by 2030 at the latest. https://youtu.be/0FehrpcR5Os?t=9890
Svensmark’s theory has been predicting cooling for about 20 years now. The trend over that period is 0.147C/decade which is even higher than the trend over the entire period of record for UAH. But yeah sure, why not give it another 10 years despite the many studies that had already put the Svensmark GCR theory on shaky ground and the nail in the coffin that CERN’s CLOUD drove home a few years ago? Right?
Best to keep an open mind.

If that were true, goldminor, then the model curve, which so clearly accelerates, could not possibly match the data so well.

Really? Arctic sea ice reflecting a lot of light in November? Did the sun even clear the horizon?
Tom, I think the bigger factor is the open water radiates more energy into the atmosphere as well as adding latent heat. This is why the winters in the Arctic are warming the most. It shows up very well in this view of SSTs.
http://www.woodfortrees.org/plot/hadsst3nh/from:1997/to/plot/hadsst3sh/from:1997/to/plot/hadsst3sh/from:1997.5/to:2015/trend/plot/none
http://woodfortrees.org/plot/hadsst3gl/from:2010/plot/hadsst3nh/from:2010/plot/hadsst3sh/from:2010
Folks, northern hemispheric SSTs continue their annual nose dive which began last month. Keep a watchful eye on the southern ocean where SSTs have begun their rise. Depending on where those (sh) temps wind up, we shall see where temperatures overall end up later this winter. Smug comments at this point add up to little more than handwaving. We won’t know where temperatures are headed until well into winter, after the northern hemisphere has presumably vented…
Don’t forget that the SH oceans are about twice as large as NH oceans and therefore have more effect on the global SST average.
Also, why do think there is an annual signal in the data ? There should be none if we are discussing monthly anomalies.
The global sea surface temp has gone up 0.5°C since 1980 and more than 0.2°C since 2010. I don’t expect temperatures a few months from now will change that much.

Personally I don’t trust those socialist oxygen molecules from which the UAH satellite temperature measurements are derived.They are trying to get poor blameless CO2 molecules to take all the blame.
As soon we can up the CO2 and get rid of the oxygen and return to our nitrogen fixing origins the better. I am sure we can manage the transition.

I can tell things are a little different from when I was a kid. Only a little.
But I’m for building 100 nuclear reactors immediately. Then start planning the next 100 and the next 100. Get 60%+ of our power from nuclear. But no one is serious, one side just wants to be right and the other side wants the other to be wrong. It’s a stupid cycle but eventually, our hands will be forced when in the 30s or 40s, by the obvious long-term trends.
100% support for more nuclear power plants.
Wind and solar are nice but ……
And, glad it’s warmer and not colder. Longer growing season.
There is a TedTalk on the nuclear issue. One person wants more nuke plants the other does not.
https://www.ted.com/talks/stewart_brand_mark_z_jacobson_debate_does_the_world_need_nuclear_energy?language=en#t-431000
Nucs are nice, but they take ten years to get the sticks down, and they cost more than other choices. And the cost of no return on your investment for ten years is a hard pill to swallow. The only way would be for governments to foot the bill.
And who knows what the price of solar, wind, and storage will be in ten years. The costs of those are still dropping.
If you want reliable power and clean air, there’s no other legitimate option than nuclear.
Renewables making the majority of our power is pie in the sky, and the fingerprint is huge. Massive environmental, land use, and aesthetic impacts. Not to mention all unreliable sources of power.
Coal plants are beautiful, but windmills are ugly.
Strip mining does not have environmental impacts but solar panels do.
Trains full of oil never blow up and kill whole towns of people.
Some places are sunny for over 90% of the daylight hours, even coal plants need to shutdown regularly to fix boiler tube leaks.
Solar and wind with battery backup is competitive and even cheaper than natural gas.
Well put, Bob.
And no one is saying we should be 100% wind or solar.
And why would that be, eh?
Bob, they put an 8-acre solar panel farm where I live. The claim is it’ll power 125 homes.
The closest nuclear plant, 70 miles away, has 2 reactors. The plant is about 500 acres. It never flooded in the historic flooding earlier this year. It powers nearly 400,000 homes.
Renewables making up the majority of our power is pie in the sky.
Indeed nuclear has some advantages. Its fuel packs the highest energy density.
But it is still a finite resource. If we were to triple the number of nuclear plants to replace coal ones, the US uranium resource will be gone in ~ 50 y.
Unless we build many breeder reactors, which add significant security and safety risks.
And, I might add, nuclear is among the most expensive to build and operate, 3 x solar or wind, 6 x gas, based on EIA stats.
Yeah, a fuel that’s produced comparably few deaths, hasn’t had a reactor completed in the US in years, understandable overregulation, cheap coal and natural gas, it would be more expensive. Crazed politicians controlling the energy and food supply are just as much a threat as terrorists.
I would argue that Nuclear is under regulated. If the Fukishima plants had upgraded their plants like how US plants were upgraded post Three Mile Island, they would have survived the tsunami without burning up and exploding.
They did not have the equipment that would prevent those explosions such as hydrogen re-combiners and reactor core isolation cooling systems that work with out electrical power during a loss of off site power accident.
You put your diesel generators behind 3 foot thick concrete walls.

Surprised to see USA 48 up.

New York -3.8
Detroit -5.7
Des Moines -4.0
Denver -2.1
San Fran +0.6
I was also surprised with L48 results given all the reports of record cold in November.
Keep in mind that the satellite data is for the “lower” troposphere, but that’s still some 15,000′ feet up, not ground level.
At 15,000 ft isn’t everything cold? I thought the reading was fairly representative of ground temperature but apparently not. Any correlations developed with ground temp that work?
The global lower tropospheric temperature anomaly for November 2019 according to UAH is 0.55 deg. C above the 1981-2010 average.
Questions for the climate experts. Is there any kind of meaning to this measurement other than what was measured? Is the 1981-2010 global average temperature the “correct” global temperature? And any departure above that “standard” MEANS that there is something WRONG with our climate?
Radiation is constantly coming and going to/from the earth. It never is in “perfect” balance. I contend that the 0.55 deg. C measurement means nothing more than the temperature of the earth at this point in time. And it really doesn’t mean anything other than that.
Correct. And given that from month to month it can swing up to +/- 0.3-0.4C, being up 0.55C in last 40 years time hardly means anything.
Rob Mitchell
“I contend that the 0.55 deg. C measurement means nothing more than the temperature of the earth at this point in time.”
Correct. That’s the reason why Roy Spencer doesn’t publish that lonesome value only.
There is also a graph showing you the last 40 years…
I discovered that graph about 5 years ago, and I’ve been watching it closely ever since. I was especially interested in how the last El Nino spike affected our weather. As I recall, there was some benefit from it. It helped end California’s drought.
Rob,
1) You seem to be implying some sort of morality by using “wrong”. The global temperature can be “typical” or “atypical”. It can be “significantly above average” or “significantly below average”. But it isn’t “right” or “wrong”. It just is what it is.
2) I am not sure what you are intending with “I contend that the 0.55 deg. C measurement means nothing more than the temperature of the earth at this point in time.” Any measurement is a measurement of conditions at that moment. The earth is currently 0.55 C above the stated baseline. Yep.
On the other hand …
That radiation balance has kept the temperature above the baseline for 6 straight years. That doesn’t happen by chance.
Interestingly, a 2-tailed T-test shows statistical significance (p<0.05) no matter where you divide the data!
* the first 2 data points are significantly lower than the remaining 490 points
* first 246 points are significantly lower than the remaining 246 points
* the last 2 points are significantly higher than the first 490 points.
Also, to respond to RW, there are only 6 swings of +0.3 or higher; there is only one swing of -0.3 or lower. It is misleading to suggest that such swings are in any way typical. This is doubly misleading since the swings are negatively correlated with the swing the next month — a swing up one month correlates well with a swing down the next, and vice versa.
Tim,
The bottom line here is these are spectacularly small changes in temperature given the amount of hype and hysteria surrounding this issue.
If the issue didn’t exist, i.e. CO2 wasn’t a GHG, no one looking at the global average temperature increase we’ve seen would think it’s anything extraordinary at all. The conclusion would just be that it has warmed a little in the last 40 years and no one would care or even give it second thought. It would be trivial.
Some decades from now when the climate change hysteria fades and believers come to their senses (one by one), historians will be baffled how so many people could have gone completely bonkers over such spectacularly small changes in temperature. And in what would generally be the desirable direction, i.e. warming. Up until recently, man has always feared cooling, and for good reason, as historically cold periods were associated with life being more difficult and less prosperous, where as the most prosperous periods where when it was warm.
Yes, the world is going ‘mad’ for sure.
RW,
The bottom line is that the issue does exist.
The causal factor for the warming is understood.
The causal factor continues to worsen.
The resultant effect is already occurring.
The resultant effect will continue to occur until that causal factor is mitigated.
If madness is doing the same thing expecting a different result, then humanity’s continued contributions to increasing atmospheric CO2 concentrations, despite the known effects, are the very definition of madness.
Good thing Nature is bringing CO2 levels back from their dangerously low levels, eh? To exterminate all human life intentionally, by getting rid of CO2, seems a bit mad to me.
@ Eh?
Couple of clarifications please:
Given atmospheric CO2 barely, if ever, exceeded 300ppm from 800,000BCE to 1950CE, why you think levels were ‘dangerously low’?
Since 1950, atmospheric CO2 has increased to 408ppm. Why do you think ‘Nature’ is responsible, what causal factors do you identify?
Literally no one is proposing ‘getting rid of CO2’. I would like to see a reduction from >400ppm to the 250-300ppm range that human life has flourished in. Shocking, eh?
Your disingenuous statements are… meh. Not even worth the time I spent typing this.
And yet you couldn’t help yourself wasting your time, eh?
It’s my time, I’ll waste it as I please.
Seems you don’t like answering questions… que?
So you’re a self proclaimed time waster, eh? Well done!
“The causal factor for the warming is understood.”
Yes, a drop in cloud cover over the tropical oceans
Hence more energy into the oceans.
Hence a couple of strong El Ninos
No evidence atmospheric CO” has any effect whatsoever.
Only an abject fool thinks CO2 causes El Ninos
spike55: Yes, a drop in cloud cover over the tropical oceans
What caused cloud cover over the tropical oceans to drop?
What is the magnitude of the effect?
How does that cause the stratosphere to cool?
How does that cause a decrease in the diurnal temperature range?
What kind of test can be used to falsify this hypothesis?
No evidence atmospheric CO has any effect whatsoever.
Say what?

Not so small.
I can feel that global average as it keeps me warm all through the winter. Even the snow sitting outside is a warm snow. Amazing.
Approx as much of warming as moving 230 miles to the south. Noticeable, but not scary. Also, remember that warming is not evenly distributed over the earth, and for some reason doesn;t seem to be happening in the us, although it does happen in europe.
Tim, I am not the one implying some type of morality. But I do find that the human-caused global warming alarmists are the ones who think in terms of the climate being “wronged” by humans. And if some of us don’t support ending fossil fuel use RIGHT NOW, then we are DENIERS!
What I am trying to get at is the 1981-2010 baseline. Is there anything at all alarming about a temperature reading of 0.55 deg. C above that average? I don’t think it is alarming at all. But some people swear up and down that humans are heating up the planet, and a runaway catastrophic global warmup is underway because of the departure from that baseline.
If the alarmists think that way, then they must think the 1981-2010 baseline is the absolute standard we must accept as the “normal” climate. And I am simply just asking, “why is that the absolute normal?”
Rob Mitchell,
There is absolutely no one claiming a “runaway catastrophic global warmup is underway”, not even McPherson claims that iirc. That is gobbledygook.
And +.55*C over the 1981-2010 baseline is “alarming” when you consider it as part of an upward continuing trend of at least 140 years, added to the fact that the 1981-2010 baseline is about +.5*C above the 1950-1980 baseline.
In less than 70 years we’ve added +1*C to global temperature baselines, not ‘runaway’ but yes ‘alarming’.
That would only be true, if all of that 1 C warming was caused by growing CO2 levels. How can you prove that CO2 was the sole cause?
McPherson is most definitely claiming that. In a video on his YouTube channel in April 2018 he claimed that most of us would be dead by October 2019. He has now deleted that video from his channel. Thankfully I saved a copy.

goldminor,
There’s an interesting article called ‘What’s Really Warming the World’ from June 24, 2015.
It shows why we know that it is CO2 that is really warming the Earth.
Interesting that the only thing that CO2 can warm is a planet, eh? Wasn’t the planet molten before all this CO2 warming started?
‘Wasnt the planet molten before all this CO2 warming started?’
And there it is. Eventually we knew that Eh?, aka Mi*ke Fly*nn, would bring that up.
Fixated in some fantasy, eh? Look it up.
Arless M., what in the heck do you think the Green New Deal is all about if it isn’t about catastrophic, runaway global warming?
Oh, I get it. It has nothing to do about climate. But all about economics.
It’s not the “absolute normal”. The average between 1981-2010 is just an arbitrarily picked baseline for the anomaly values. Any baseline can be chosen. Temperature changes and trends are not dependent upon the choice of baseline. The baseline is not meant to represent anything “absolute” or “normal”.
bdgwx,
the 1981-2010 baseline is not ‘arbitrarily picked’, it’s the baseline for Dr Roy Spencer’s UAH Satellite-Based Temperature of the Global Lower Atmosphere or the baseline of the blog you are replying on.
It’s the base of the first 32 years of the UAH Troposphere temperature readings, the first baseline of satellite based readings in history.
Not arbitrarily picked at all.
Arless, the point (relative to this thread) is that this period was not chosen as any sort of “right” or “best” or “official” temperature of the earth. It is simply a *convenient* baseline for comparison with other times. “Convenient” because 1) it is well-measured and 2) it is familiar to most people alive now.
Arless, I think you missed the point. The average between 1981-2010 is arbitrarily picked because the UAH team could have picked any 30yr period, a single year, or even just fixed it at 15C. There’s no one reason that forced them to pick 1981-2010. Different groups use different baselines and that’s okay because it doesn’t matter.
And he has changed the baseline period. It used to be 1980-2000 I believe.
Well that is true, they could use a 30 year UAH baseline of 1990-2019 which would also show less LT warming.
Since the Satellite records only start in 1979 it seemed obvious (or not) that that was their reason for the 30 year baseline start.
Arless says: “they could use a 30 year UAH baseline of 1990-2019 which would also show less LT warming.”
The warming is the same no matter what baseline is chosen. The only thing that would change is the ‘spin’ that people could put on the results. The absolute number for November might become 0.4 instead of 0.55, but the important metrics would not change one bit.
* This November would still be the warmest on record.
* The warming rate would still be 0.13 C/decade.
The amount of warming would be exactly the same regardless of whether they chose 1990-2019 or 1981-2010.
As Nate already pointed out 1981-2010 wasn’t the original baseline chosen. It has changed along the way.
Again…that’s fine because it doesn’t matter. There’s nothing special about 1981-2010 or any other baseline.
The 30 year climate average period comes from the UN’s World Meteorological Office and is part of “that’s the way it’s always been done, I think going back to days when the 30 year period was originally chosen because it fit on the ledger paper that was handy.
Yikes, another unusually warm month.
Looks like it is about time for Dr. Spencer to release v7.0 and knock the temps down a bit.
J.W.
His regular monthly adjustments in recent anomalies have actually tended to be increases. Funny how deniers don’t jump on his back about that, as they do with the land-based data sources.
Des, please stop trolling.
Somewhere uptheread, I read one more time: “no warming since 2016!”.
And one more time I ask in turn: How could there be any warming since the highest anomaly UAH has ever measured and computed?
And one more time I show this graph comparing the periods 1997-2001 and 2015-2019 relative to their respective begin:

The warming which occured within the LT since 1998 certainly is not dramatic! No reason nonetheless to ignore it.

Bindidon, “not dramatic”?
In the case of your blue line scenario your graph shows more than +.2*C per decade and the orange line shows well more than +.3*C per decade. Those are both more than Dr Spencer’s UAH Lower Troposphere +.13 per decade and his UAH global surface of +.18*C per decade by a good margin.
It only took -5*C to give the planet an Ice Age (kinda ‘dramatic’), so +3*C in a centuries time should probably be considered ‘dramatic’.
Not surprising what the satellites are showing. This current leg of these warming trends started in the late 1970s. Let’s see what the graph looks like in 2030. I would bet on a downtrend over the next decade, and into the 2030s.
A decade ago, you people were making the same prediction about the 2010s.
My thoughts have changed a good bit over the last 10 years. Ten years ago I was still in a very early stage of learning. I made no predictions back then. Since early 2014 though I have had some success in predicting what I see as cyclical events within the climate system.
Not a good bet. You should look for 100:1.
Take a look at the inexorable climb of ocean heat:
https://www.climate4you.com/images/World3monthTemperatureSince1955Depth0-700m.gif
Its where most of the heat is going. Even ignoring the 10 year lag of the effects of today’s emissions (Thats right, the maximum effect of CO2 warning happens about 10 years later – maybe you mean cooling by 2040?), only the deeply deluded would look at that graph and say temperatures are about to plunge and revert to below average and the Arctic is going to regain the 75% of melted sea-ice when all of the science says the exact opposite is going to happen. Even lukewarmers like Roy (“more carbon dioxide is better than less”) are back-pedalling.
You’re backing a lame horse.
Where did I make the claim that temps are about to plunge? Your comment about how I view the picture is false. Your words have zero to do with my overview of the climate system.
Arless Mcgee
What are you telling here?
The graph I posted has nothing to do with any trend info: no one computes trends based on so short a period.
The UAH LT trend for Jan 1999 till now is 0.15 C / decade.
Nothing dramatic.
Bindidon,
I was pointing out that your blue line shows +.46*C over that 20 year period and the orange line shows a difference of +.64 over the same.
As not a scientist that looks like +.23*C or +.32*C per decade for that particular graph.
You state the UAH LT trend is +.15*C per decade since 1999, even as no one computes so short a trend, except your graph shows a much higher trend per decade over that same period, almost double the +.15*C trend.
Was pointing out that that seems much more dramatic is all.
Arless McGee
Again and again, I ask you where you see ‘that 20 year period’ in my graph comparing two superposed sequences of 58 months each:
– Jan 1997 – Oct 2001;
– Jan 2015 – Oct 2019.
Didn’t you understand the graph?
Nicely put.
I guess its kind of inconvenient that Dr Spencer’s 13 month average (which is basically a year ahead now of the last calendar year average) pretty much negates the argument put by McKitrick in the article Spencer re-blogged 2 weeks ago….
Yes Dave,
It might be interesting to see how the McKitrick argument goes with the more recent UAH data filtered using a Loess filter.
see – https://i.postimg.cc/0QdkYVzS/UAH-Loess-12-month.jpg
You can see that the US is warmer than a month ago.
The deniers are spinning like dervishes!
The fact that it is warmer doesn’t mean the deniers are wrong, nor does it mean you’re right (about whatever you’re on about)
The fact that it is warmer means only that it’s warmer. It doesn’t mean AGW is at hand or any such. Or can you prove that it does, outside of the programs designed to prove such.
By itself the continued warming doesn’t mean the deniers are wrong. There’s lots of other evidence against their position.
He’s just another information free fanatic, eh?
Check out the last 3 reading for the south pole:
-0.04
0.98
1.59
Could the Antarctic SSW still be impacting us? We also have one trying to form in the NH as well I heard.
Yes. I think so. MT and TP temperatures actually increased this month down there. LS is still elevated as well.
Still no evidence here of a northern SSW. The effects of the Antarctic SSW are definitely still being felt. We see a drop in both the arctic and NH mid latitudes. The tropics, SH mid latitudes and especially the south pole are still elevated. Once we see the stratosphere cool over the south pole region, we will know the effects are waning. There is no way a change in 2 months from -0.04 to 1.59 can be sustained there. Fast pops tend to be followed by fast drops.
Watching the alarmists get all excited about +0.55 C due to the Antarctic warming by 1.63 degree c is hilarious… like they’ve won some kind of award and suddenly the arctic will be free of ice year round and snow / cold will be something only found in the history books. It is SO cold in the Antarctic that almost nothing lives there except at the coast. 1.63 deg c won’t make any difference at all, except probably pile even more snow there that will never melt. lol
Well, yeah, it’s just one month. And I agree that the current warmth in the SoPol region isn’t going to be sustained for very long. But, the +1.59 reading isn’t that unusual either. +1.55 occurred in 2016 and +1.52 occurred in 2012. Both of those appear to be related to SSW events as well. The SSW events in 2012 and 2016 were much weaker according to the TLS data so that does raise the question of why the +1.59 is relatively low. At any rate the SoPol only represents < 7% of the planet so it's not a huge contributor to the global mean temperature anyway.
right… the tropics at +0.55 plays a much bigger roll in the up tick then the south pole. Interesting that it is still at that level even though El Nino has ended. Could be the SSW extending that… could be a late onset of annual trade winds due to the solar min, I’m not sure. Anyways… the tropics were below baseline as recently as April of 2018. I’m sure they will go there again.
Also, I’m not sure why the USA 48 number is so high. It was a major negative departure last month per NOAA stations.
So November 2019 is the highest November LT result on record?
The decadal average 1979-1988 for Novembers is -0.14.
So we have now experienced 0.69 warming in 40 years.
Presumably, science says, this trend will continue while ever GHG concentrations continue to increase.
41 years in the data set (almost).
Average of 0.013 warming per year.
41*0.013 = 0.533 warming.
And yes, it will continue warming until the causal factor is mitigated.
Until the seas boil again, eh?
Your satellite must be adrift , the Russians hacked it
Laika the Russian canine agent lives!
A wave in the stratosphere indicates that it could be even warmer in the far north.

Des, please stop trolling.
Perth Australia has posted its earliest 40-degree day in December on record as the city experiences a sweltering start to summer on the heels of a record-breaking November.
Now you can see why the BOM abolished the heat wave of 1896, eh? Just declare all official temperatures before 1910 unreliable. Clever move, eh?
You mean the heatwave that occurred ONLY in January 1896, and ONLY in NSW and Queensland?
Anomalies for Sydney (Daily Highs) for each month of 1896:

Jul -3.04
Aug -2.78
Sep -1.81

1896 average: -0.81
Perth, Western Australia. 6 January 1896. 109 F – 42.7 C. 1884 was hotter, 114 F – 45.5 C. You are trying to spread misinformation, eh?
So now you are down to ONE day. Hilarious!
Meh?, It appears from the records that Stevenson screens were first installed in Perth on January 1st 1897.
See – http://www.waclimate.net/bureau.html .
As hilarious as the one day referred to previously? Don’t you alarmists know the difference between weather and its average, climate?
Not understanding the difference between weather and climate is the domain of deniers.
BTW – good to see you are not challenging the fact that 1896 as a whole was not a warm year in Sydney. More than 3C cooler on average than 2019 – 4C if you insist on accounting for the lack of Stevenson screens back then.
Des, please stop trolling.
But they are unreliable, they were not even in Stevenson Screens. Some were on Glaisher Stands, but they read 1C too high. Most were just hanging under verandahs exposed to ambient and reflected radiation.
Clutching at denial straws.
So official records of Stevenson screens installed at high order stations from 1880 are wrong? How about dated photographs of the time? Keep dreaming, eh?
Some of the data IS reliable enough to go back before 1910. For example, Sydney’s record goes back to 1859, and the FULL Sydney data set is given by the BOM. But there is not enough reliable data to combine into state and national averages, which is why they only go back to 1910.
So the lack of Stevenson screen enclosures is only used as an excuse when it suits you, eh?
Temperature records taken without Stevenson screens were systemically HIGHER than those with them, by about 1C I seem to recall. The 2010s in Sydney are averaging 2.5C higher than the 1890s according to the record. Would you like me to account for the lack of Stevenson screens and make that a more accurate 3.5C ?
So if the subject relates to Perth, you concentrate on speculation about the other side of the continent, eh?
Here is the 60-month rolling mean for UAH:

It can be seen how strongly El Ninos affect the 90th percentile and La Ninas strongly affect the 10th percentile. But those extreme events have little effect on intermediate percentiles, so it can’t be argued that the latest median is “only due to the 2016 El Nino”.

Nice posts. One for the ‘coolists’ to roll around on their tongues.
Or rattle around inside their brain cavity.
Des, please stop trolling.
Thanks for showing the zero trend period from 1999-2016..
while CO2 continued to climb 🙂
So NOT CO2 causing this beneficial warming.
You’re so close, but so far.
UAH trends for various periods using the annual average anomalies:
1999-2016: 0.126 degrees/decade (including an El Nino year on the back of your period totally ruined the point you were trying to make)
1999-2015: 0.063 degrees/decade (cut out the El Nino year, but still stubbornly showing warming)
1998-2016: 0.049 degrees/decade (included El Nino years at start and end, very slight improvement in reducing the trend)
1998-2015: -0.01 degrees/decade (start data set with El Nino, cut data off to exclude El Nino at end… the perfectly cherry picked data set for your point)
What’s my point? Oh, yeah. In any data set with plenty of short term variation, subsets of data can be cherry picked that doesn’t reflect long term trends. So if you’re going to cherry pick data, don’t be bad at it.
That 0.126 should have been 0.12
Yes Joel, the UAH data contains lots of El-Nino wiggles superimposed on the lowest long term trend. That’s why Pauseniks are such UAH fanboys. So many opportunities to cherry pick the lowest trend they can find. These trends are always statistically insignificant but they continue with the zombie argument regardless. Sad really.
You can cherry-pick several zero and negative trend periods. Yet the planet still warmed overall with a trend of 0.131C/decade. The many zero and negative trend periods along the way are not inconsistent with CO2 forcing or any positive forcing agent.
Only the LT warmed at +.13*C, the surface warmed at +.18*C according to Dr. Spencer’s UAH graph stated above.
There’s a difference between the lower troposphere temperatures and the surface temperatures of 3-4 kilometers iirc. Dr. Spencer has done posts on how lower troposphere temperatures are derived.
And if the planet has warmed overall as you say then that is completely consistent with additional added CO2 over the same time period.
UAH doesn’t measure the temperature near the surface. Their TLT product is the lowest in elevation though it is likely getting at least partially contaminated from the stratosphere. The TLT trend is 0.131C/decade.
RSS’s TLT product is weighted a lower in the atmosphere still. Their TLT trend is 0.18C/decade.
BEST is a surface dataset. Their trend is 0.19C/decade over the same period.
But yes, long term secular warming is consistent with CO2 forcing. Zero or negative trends over short periods that have been cherry-picked are not inconsistent nor do they falsify the hypothesis.
The warming in the lower part of the atmosphere by itself is not sufficient to eliminate causes. However, the simultaneous cooling of the stratosphere does. CO2 (or GHGs in general) are consistent with this observation.
bdgwx, please stop trolling.
Does the northern hemisphere include everything done to 0 latitude or what?
https://www.natice.noaa.gov/pub/ims/ims_gif/DATA/cursnow.gif
The map in your link shows the entire northern hemisphere down to the equator.
Des, please stop trolling.
Would a northern hemisphere above 45 degrees be a useful category to show?
As I said above, your map shows the entire northern hemisphere. Not sure where you are getting 45 degrees from.
That is what I am asking how much of the northern hemisphere does UAH sat temps include in their NH category and above 45 degrees seem to be colder than below 45 degrees showing a different climate zone looking at all the snow above 45 degrees.
They give an anomaly for
(1) the Arctic and Antarctic (between 60 degrees and the pole)
(2) the northern extension (between 20 degrees and the pole)
(3) the tropics (between 20S and 20N)
A simple calculation (as per bdgwx’s formula), will give you the anomaly between 20 degrees and 60 degrees (although you have to assume that each half of the tropics has the same anomaly).
Des, please stop trolling.
donald, The files include the latitude boundaries for each category. NH is 0-90N. To get the proportion of area above a certain latitude use 1-sin(lat). So 45-90N would be about 30% of the hemisphere. The NoPol region is 60-90N and represents about 13% of the hemisphere.
So the northern tropics is included in the NH temperature as well as the tropics temperature. Why cannot we have tropics temperature then exclude the tropics from the other two n/s temperatures?
donald, Yes. NH includes the northern half of the tropics. Remember NH is 0-90N which includes 0-20N. You also have NoExt which is 20-90N to work with as well.
bdgwx, please stop trolling.
The rest of the week is expected to remain anomalously cold across vast swathes of Australia, too with temps holding well-below the December average.
In Melbourne, for example, residents will likely have to wait until next Sunday for any warm-up.
Despite these real-world observations, the BOM are sticking with their original summer forecast, with stubborn senior meteorologist Michael Efron saying: climate indicators suggest were actually in for a warmer and drier than average December.

Folks… here is the UAH map for November.
https://www.nsstc.uah.edu/climate/2019/NOVEMBER2019/201911_map.png
Now see these locations and departures last month per NOAA in deg F:
New York -3.8
Atlanta -1.5
Detroit -5.7
Little Rock -5.3
Des Moines -4.0
Dallas -3.1
Amarillo -1.8
Denver -2.1
Flagstaff +1.7
San Fran +0.6
LA +2.5
What does this prove? The UAH doesn’t represent the ground temperatures well at all… you know, where all the glaciers are? Lower troposphere is important, but it’s not the same thing as ground temperatures. Has anyone ever studies a link between the 2? Like one leads the other?
Compare with the lower stratosphere.
https://www.cpc.ncep.noaa.gov/products/stratosphere/strat_a_f/gif_files/gfs_t100_nh_f00.png
The temperature anomalies in the stratosphere are much higher than at the surface. Unfortunately, there is confusion here.
There are no temperature anomalies on your map, only temperatures.
It also has nothing to do with the comment you were responding to.
But thanks for your admission in your final sentence.

Yes Scott,
The UAH LT data does not represent surface temperatures very well. RSS TLT satellite data does a better job. You can check this by correlating both data sets against the surface data such as HAD*RUT, GISS, NOAA, Berkeley etc..
Additionally the RSS data has long term trends that better match the surface data than UAH. The lower long term trend values for UAH is why the UAH fanboys here love it and hate RSS and the surface data.
By the way, what’s left of the Himalayan and Andean glaciers are definitely up at altitudes more relevant to the UAH data.
RSS aligns better with the many reanalysis datasets commonly in use as well. That’s okay. UAH is still useful because it provide a lower bound to the warming trend.
Funny, I think of others as upper bound, worst case, and UAH as the benchmark. I doubt there’s any other dataset as scrutinized and validated as UAH.
argus,
What do you think is special about UAH that gives them a monopoly on correctness?
What do you think the odds are of more than a dozen datasets maintained by independent groups using wildly different techniques and subsets of available data getting roughly the same warming trend by accident?
It would be nice if UAH would release their methods and source code so that experts can better assess why it is outlier relative to most other datasets.
My understanding is UAH has the best match with balloon data.
On a global scale RSS has the best match.
https://tinyurl.com/rlykp5j
MikeR
But surface readings are biased due to the heat island… I actually think UAH matches the HADSTT3 better than RSS. I’ve shared that study here before. Anyways, we just need to realize that lower troposphere is not the same as ground temperature.
Why should we expect TLT trends to match SST trends?
The ocean is the ultimate heat bank for the planet, and make up the majority of the surface. The land, atmosphere always follows the ocean. (eventually) Ocean currents from what I can tell are responsible for most of the climate trends on the planet. Anyone trying to prove man’s influence will have to prove to me that we are impacting the ocean currents somehow.
Did you know US is a tiny bit of our globe?
Petter Brkeeiet,
Once you prove one area can not be trusted for an accurate monthly ground temperature reading, we can’t trust any of them.
I hope people do not confuse my observation as a complaint about Dr Specer’s work. The alignment between UAH and HADSTT3 is much better than RSS and HADSTT3… but the information does have it’s limits.
Scott, yes if you use HADSST3, but from memory, RSS aligns better than UAH with HADSST4 . Check it out.
Too lazy to check it out yourself, eh?
Meh, usually your comments are as useful as tits on a bull but you spurred me to try and find my old spreadsheet (unsucessful).
But I have just redone it and I was wrong UAH is significantly worse than RSS for both HADSST3 and HADSST4 .

I must be also suffering early onset dementia. Perhaps there is a contagion about. Who knew you could catch it via the internet?
Anyway here are the correct scatter plots for UAH and RSS showing that RSS correlates better than UAH with HadSST3.

Hi Scott,
Firstly if you look at the above comment at
http://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-412438
I have include a link to a graph showing the correlations between UAH, RSS and SST3. RSS correlates significantly better (R2=0.76) than does UAH (R2 =0.58).
With regard to your Facebook entry I have confirmed your graph which suggests we are at least using the same data.
Here is my version.
https://i.postimg.cc/wvBk0xrj/Differences-SST3-UAH-and-RSS.jpg
However the devil is in the detail , RSS and UAH diverge after 2002.
In this regard the differences between SST and RSS progressively drops to around zero at present while the difference between SST and UAH continue to increase.
Here are the historical data in the two different time periods. From 2002 UAH is way too low while RSS follows the SST data more closely.Pre 2002 both RSS and UAH are very similar and both are too low.

There is no reason that the lower troposphere has to have an identical temperatures to the ocean. The point of this exercise is the importance of how you present the data. Maybe we can jointly author a chapter in How to Lie with Statistics – Aided and Abetted with Graphs.
Scott, I am pleased that you are presenting data unlike the remainder of your innumerate colleagues who like to proclaim loudly their abilities without backing it up with anything that even remotely resembles Science, unless you are into the paranormal.
Why not just look directly at the HADSST3 data? It shows the oceans have warmed 0.5C in the last 40 years, a rate of 0.14C/decade.
Kreg, please stop trolling.

November is getting VERY cold in the Midwest… in fact in 40 years of recording data, it has never been this cold. The last 2 years we failed to hit 60 deg F in Detroit MI. in the month of November. We hit 60 deg 13 times in 2015. We hit 50 deg F 24 times in 2001, 6 times this year, 5 times last year. Tied for 2nd, and lowest number of 50 deg days.
https://www.facebook.com/100000276969216/posts/2816124645073407?sfns=mo
November temperatures at least in Detroit MI. seem suppressed by solar minimums.
Yet solar minimums don’t really correlate well with lower global Earth temperatures since the major rise of CO2, so maybe it is just Detroit.
The 14th minimum was the lowest since the Dalton minimum yet globally Earth’s temps started to rise right in the middle of it in 1910. The two minimums before 14 were low-moderate also.
And not to mention the past two minimums we’ve just experienced.
It will be interesting to see how ‘cold’ Detroit gets when solar irradiance plus solar sunspots go back up into their higher planes in the coming years yes?
Arless McGee
For most of the year, Detroit follows the AMO. I just think it is a curious stat that we follow the solar min for November. Most of the time, the solar cycle impacts ENSO on a delay of a few years. With a GSM on the way, the good times are over. The last 6 solar cycles were the strongest of the last 400 years. Even the last one.
Hi Ren
Maybe the heat is leaving the planet because of the lower sun input on the outer of the atmosphere by confection and is showing odd readings as it passes through various levels
Or something like that

Have you tried email?
Snape,
I usually use NOAAs map, but it had not been updated yet for November last time I checked. I just took some spot readings from the NOW data to determine there was a major negative departure for the US last month.
Snape thanks this tool is useful.
Snape I’ve already had a complaint that the tool is biased. lol Guess I will have to check the NOAA map when it comes out.
You need a lot of storage to smooth the fluctuations or nuclear, gas, coal. There are even some days a year in Germany with almost no solar and wind. https://www.dropbox.com/s/tu0pwuiae4usecr/Energymix-Germany-Jan-April-July-Nov.jpg

[Once you prove one area can not be trusted for an accurate monthly ground temperature reading, we cant trust any of them.]
???….. the UAH products dont read ground temperatures for any area or month.
Nor does anyone else, eh?
You dont know much about gardening, eh?:
To measure the temperature of the soil, use an instant-read thermometer made for cooking. Push the thermometer’s probe as deep into the soil as possible to get an accurate reading of the soil temperature.
https://todayshomeowner.com/how-to-measure-soil-temperature-for-planting/
Nope. You are not reading the surface temperature, eh? Nor do NASA, NOAA, BOM, or any of the others. They just pretend they do, and you pretend to believe them.
And your evidence for the assertion regarding NASA, NOAA and the BOM is?
NASA, NOAA, and the BOM. Look it up, eh?
So you don’t trust the BOM? You prefer to gauge wind speed and direction using a wet finger?. That could be a very dumb idea if you get hit by another Tracy or even a Marcus.
Trying to play the diversion card, eh? You do realise that wind speed and direction are not surface temperature?
Yes wind speed is measured at 10 metres. So Eh? you only distrust measurements for heights less than 10 metres. How strange.
So getting back on track, what is your specific evidence regarding NASA, NOAA and the BOM? Stop beating around the bush and let it rip.

Oh well.
What are the view factors for the plates in Geraint’s experiment?
He’s a couple of six-packs short of a six-pack.
So he fails to show a lack of an effect.
Shoddy science.
It shows your lack of critical thinking skills and your lack of skepticism.
The first cult member descends…
(“member” is the appropriate word)
That’s all you got, no critical defense of the crappy experiment?
I wasn’t aware you had made an attack.
Search the site for “blob” you might find where I described the experiment as faulty.
Also I asked you specifically about the view factors involved.
I also discussed the temperature drop, which shows poor experimental design, he needed the temperature to be the same when he introduces the second plate.
I also noted one can not prove that there is no green plate effect just because you don’t observe one.
Do try harder, you are just unquestioningly accepting stuff that aggrees with your “religion”
I didn’t know I was supposed to repeat an argument you already lost.
I assume people are capable of clicking on the link and reading through all the comments. They can also take a trip over to the previous article to see you squawking like a ridiculous man-child, uttering such choice phrases as “Quitter Quitter chicken shitter” (if they fancy a laugh at your expense).
Did he really say that?
http://www.drroyspencer.com/2019/11/climate-extremism-in-the-age-of-disinformation/#comment-412338
And who is the ridiculous man-child that calls me “blob?”
Sorry, but I like to get down in the mud and wrestle with the pigs.
Calm down, blob.
I see you are shifting into your I lost the argument mode and are changing the subject.
Do try to keep on track, even when you are losing.
Care to address Geraint’s view factors?
Care to elaborate on what your problem is with the view factors? The plates are parallel, and close to each other.
They are blocked by the plastic spacers, or did you not notice that?
Yes, the plastic spacers have been discussed already. Point?
It shows shoddy experimental design,
Geraint even admits they are not the best way to do the experiment.
“Yes I can repeat it with hangers. In fact I am trying to devise how best to do that right now.”
Oh, so you didn’t really have a point. There are two stacks of spacers either side of the plates, to keep them separated. You mentioned view factors because you thought it might confuse some people into thinking you had something more important to say, when in fact you’ve not elaborated on any difference it would actually make. His comment about repeating it with hangers was actually made in response to Norman’s point about conduction through the extremely low conductivity plastic spacers, to which Hughes responded with appropriate lack of concern, but said he would try to improve the design anyway. All seems pretty reasonable.
People can just read the comments for themselves, though, blob…no need for you to take partial quotes of comments out of the correct context in order to try to generate some controversy.
Well there is also this
“I also noted one can not prove that there is no green plate effect just because you dont observe one.”
which you haven’t addressed.
Care to swing and miss at this one too.
And the temperature went down, that falsifies his experiment.
You haven’t addressed that either.
And the spacers reduce the are of both plate and introduce an unknown amount of heat transfer between the plates.
Three strikes, you’re out.
““I also noted one can not prove that there is no green plate effect just because you dont observe one.”
which you haven’t addressed.”
There is no way to prove to anything to you people.
“And the temperature went down, that falsifies his experiment.”
Does it? Why’s that? Not even Swanson had a problem with that. Read through the comments at the experiment link.
“And the spacers reduce the are of both plate and introduce an unknown amount of heat transfer between the plates.”
We already discussed that.
Looks like it is about time for me to collect data using my own version of the “green plate experiment” using low-cost items you could buy at a local hardware store. I designed the experiment to minimize conductive and convective transfers, and to maximize radiative transfers. Preliminary data showed a clear signal from “backradiaton”, but then I got busy and shelved the project.
Maybe I could publish the results at Principia.
OK, Tim. We’ll file that one under “hearsay”.
Maybe you’re dreaming. Pinch yourself and see.
In the comments over at the last article at Dr Roy’s, it’s been agreed that insulation does not make the actual heat source hotter…in other words, the insulation on a satellite doesn’t make the sun hotter, and the insulation in your house doesn’t make the actual heat source within your radiators hotter.
With that agreed, we now move over to the 3-plate GPE setup, with a heated middle plate, and two green plates either side of it, separated, in perfect vacuum. All plates are black-bodies, perfect conductors, no radiative losses past the edges of the plates. The heat source is the central plate. You could argue that there is a heater inside it, and that’s the heat source…but, since the plates are perfect conductors anyway, effectively the entire plate is the heat source.
So, put the two together…it’s already been agreed over there that insulation does not raise the temperature of the actual heat source, the blue plate is the heat source…and that’s that. It has been tacitly agreed that there is no GPE. The debate is over.
(You can add the fact that a perfectly conducting BB plate is not an insulator anyway, as well, if you wish)
Game over.
I don’t agree with any of this muck.
Insulation does indeed raise the temperature of a heat source.
Sorry charlie, you are out of your depth here and don’t know what you are talking about.
One of your cult members disagrees…when one of the cult strays, they must be punished.
Read on, from here:
http://www.drroyspencer.com/2019/11/climate-extremism-in-the-age-of-disinformation/#comment-412303
I don’t see any disagreement, care to elaborate.
One of your cult members said, quoting me:
“The air in the house does [warm]. The actual heat source within the radiators, does not”
And responded:
“Precisely, the air warms just as the Blue plate warms, not the heater supplying the 400W to the Blue plate”
So they agreed, and likened the heater supplying the 400 W to the blue plate as the heat source within the radiator, that does not warm when the house is insulated.
But, as I have explained, the blue plate is the heat source, since it is a perfect conductor. Trying to argue whether there is a separate “heater” within it, or not, becomes irrelevant.
Your position is that you now have to defend the concept that insulators actually make the heat source warmer. So putting insulation around your house actually makes the radiators warmer.
I think you might be in trouble.
The comment below is dedicated to DReMT and the other members of the brain trust. It involves the original 2 plate setup but , upon request, the 3 plate setup could receive the same treatment.
The following are spreadsheet calculations of the radiant powers and temperature of a plate that is acting as a heater (either re-radiating as in the Eli Rabett setup or generating heat internally ). This plate, as per usual, is receiving radiation back from a second insulating plate.
The only difference to the earlier calculations is that this spreadsheet extends to include different emissivities for the insulating plate.
Here is a link to a screen dump of the calculations.
https://i.postimg.cc/SsqjbqzF/calculations-Insulation-via-Green-Plate.jpg .
The source (blue plate) is generating 400 W. The temperatures of this plate are calculated when insulated by a plate of differing emissivities ranging from 0 (mirror – 100% reflectivity) to 1 (black body – 0% reflectivity) , Also shown is the temperature of the blue plate in the absence of the insulating plate. All the calculations are done using the standard energy balance equations and the S-B law.
The increase in the source temperature , relative to the temperature without the insulating green plate, ranges from 18 degrees K for a black body to 46 degrees K for a white body (mirror).
What is interesting, but perhaps not that surprising, is that exactly the same macroscopic equations can handle both types of radiation, back reflected and thermal back radiation, even though the physics at the microscopic atomic level differ.
I know that this material is unlikely to get through to committed ideologues, particularly those who are also scientifically illiterate and innumerate, but hey, why not give it ago.
You never know, there may be someone reading these exchanges who is genuinely interested in learning.
…and by “the standard energy balance equations” you mean, “Eli’s math”.
Keep on chanting, “the math is the life…the math is the life…”
DReMT, I am not sure why you are so terrified of math. Solving simultaneous energy balance equations is not terribly difficult. It’s not like you have been asked to solve Fermat’s Last Theorem as it’s actually just year 10 math.
I am really not sure how you have survived so far without even the ability to simply balance a ledger. Your personal finances must be a total mess.
Here is a link to an article by someone who shares a similar affliction.
https://chrisguillebeau.com/cant-learn-math/ .
The math is fine, in and of itself, but it still leads you to the wrong answer, because the physics is wrong.
DReMT,
I am glad you agree that my maths is correct. What particular aspect of the physics is wrong?
You already know, as it has been explained at great length, in multiple discussions, that you have been a part of (or have seen linked to since)…so why pretend otherwise? I will answer for you: it’s because you hope I will get bored of repeating myself, and so will not answer, thus making it appear to readers as though I have no answer. This, I refer to, as playing “the game“.
DReMT, Please explain to us unfortunates, who do not understand you, just once more your concise interpretation of the either the 2 or 3 plate problem, but this time with feeling. We are desperate for enlightenment.
Still playing the game, I see…
Yes the game of whack a mole. Just stop evading.
I literally just finished explaining to you what “the game” is…and now you’re playing it!
DReMT , I think your concept of the game is ill defined. I believe the rules are very simple and concise. Keep pointing out that the opponent has no idea what he is talking about and refuses to engage on the scientific merit of his theory. His only option is to evade.
This game also goes by the name of ‘Catch the Greasy Pig’ and DREMT is so well insulated by his layer of grease that he may expire of heat stroke.
I hope that DREMT is not too offended by the above. He may now pull out the victim card as this could be another way to evade.
I have offered him other exit strategies in the recent past, such as going quietly or actually responding appropriately, but he seems to always want to dumb down.
However he is welcome to terminate the game and respond to my original post. Here once again is the relevant diagram
https://i.postimg.cc/MZ9DGRbp/three-plates-DREMT.jpg .
That’s great…keep the demonstration going…
Nope I’m good, insulation makes the heat source warmer.
I win, you are losing.
Though the case where the heat source is regulated to achieve a certain temperature, and turns on and off to maintain that temperature, with more insulation, the heat source turns off more, if it stayed on, it would indeed get warmer.
But that isn’t the plate experiment either, that case has a constant input of 400 watts from the heater and also input from the green plates which increase the temperature of the blue plate according to the laws of thermodynamics which you still refuse to understand.
“Nope I’m good, insulation makes the heat source warmer.“
Wow…OK, then.
“But, as I have explained, the blue plate is the heat source, since it is a perfect conductor.”
In the two plate problem, which my quote applied to, the Blue plate was not the heat source, and it WARMED just as the air in the house warmed.
So you agree that the BLUE plate warms in the 2 plate case?
Ok.
“So, put the two togetherits already been agreed over there that insulation does not raise the temperature of the actual heat source, the blue plate is the heat sourceand thats that. It has been tacitly agreed that there is no GPE. The debate is over.”
This is how DREMT understands heat transfer, pattern matching. If something happens in one setup, it MUST happen in all setups, he thinks..
Wrong and dumb.
Every problem is different, and thats why one needs to understand the basics.
“But that isn’t the plate experiment either, that case has a constant input of 400 watts from the heater and also input from the green plates which increase the temperature of the blue plate according to the laws of thermodynamics which you still refuse to understand.”
Your position is simply that in a hypothetical scenario where the only three objects in existence are a heater at 244 K and two passive plates, the passive plates warm the heater to 290 K.
You defend this position as if the people questioning it are stupid, or insane.
if the shoe fits, you gotta wear it.
Your opinion on the green house effect is pure evil.
People are dying.
Wash your hands.
That’s the way. Keep it rational.
Seems the thing to do when talking to an insane person.
I think if people are dying, perhaps it would be best if we concentrated on helping them, rather than wasting a fortune on a non-existent problem.
Maybe a movement based on lie after lie is probably not “good”. Getting a young girl to go around the world scaring children and telling them they have no future might not be…positive.
Nobodies making Greta Thunberg do that.
The greenhouse effect is not a lie, it is consistent with all the known physics of poly-atomic gaseous molecules.
You don’t think all the scare-mongering she’s been exposed to over those formative years might have, “stolen her dreams, and her childhood”?
I’m sure it was all good scare-mongering, and not evil scare-mongering, though. So, that’s the main thing.
“Your position is simply that in a hypothetical scenario where the only three objects in existence are a heater at 244 K and two passive plates, the passive plates warm the heater to 290 K.”
And here again he alters facts like boundary conditions to match his beliefs.
There is no plate held fixed at 244 k. There is only a plate with constant heat input of 400 W. Its temperature will be whatever it needs to be to have 400 W output. Which, with green plates present MUST be 290 K. Just the way it is.
Again DREMT, completely unable to apply heat transfer basics to different situations, 2 plates separate heat source, 3 plates one plate heated, a house with air and a furnace, he mixes them all up and relies on the mistaken view that their qualitative behaviors should match each other.
Of course this approach is ignorant and destined to fail, as it clearly does.
This may be of interest, to some:

It is not difficult to predict that ionization of the lower stratosphere by galactic radiation increases during the minimum solar activity, which causes the temperature of the lower stratosphere to increase.
About once a week, Spaceweather.com and the students of Earth to Sky Calculus launch a helium balloon with radiation sensors to the stratosphere over California. This is a unique monitoring program aimed at tracking the cosmic ray situation in Earths atmosphere. During each flight, our balloon passes through something called the Regener-Pfotzer Maximum, a layer of peak radiation about 20 km above Earths surface.

If man made climate change is happening and I think it is………individual people and private developers of green energy need to do at their own will to offer and buy products they see fit…….the government and tax revenue need to stay out……people should still have a choice to drive or live as they see fit. Buy or develop products as they see fit
Erich says: “people should still have a choice to drive or live as they see fit.”
While I sympathize to some extend, I would ask where you draw the line on government involvement. Should government be involved in requiring seat belt & air bags? In setting speed limits? In limiting the weight of semis on the road? In regulating pollution from cars? Are those also my personal choices that I may make as i see fit?
Should I be free to dump toxic chemicals into the stream behind my house?
The point is that we live in an interconnected society and it is exactly the job of government to address how we interact. If people think something is important, then government *should* address the issue. (The challenge, of course, it deciding what is good for society as a whole, an then finding ways oto bring about those goals).
Pollution is the best example.
Consumers can make a rational free choice if third party costs are priced in.

Tim makes a good point.
Individual voluntary choices to go green have little effect.
Just as very few would pay taxes, if they were optional.

Phew, glad that cooling spell is yet again being predicted really soon. I’d be really worried if I didn’t see that a complete failure to grasp reality lets people survive for years on end.
New meta-study over at Geophysical Research Letters:
“Retrospectively comparing future model projections to observations provides a robust and independent test of model skill. Here we analyse the performance of climate models published between 1970 and 2007 in projecting future global mean surface temperature (GMST) changes. Models are compared to observations based on both the change in GMST over time and the change in GMST over the change in external forcing. The latter approach accounts for mismatches in model forcings, a potential source of error in model projections independent of the accuracy of model physics. We find that climate models published over the past five decades were skillful in predicting subsequent GMST changes, with most models examined showing warming consistent with observations, particularly when mismatches between model‐projected and observationally‐estimated forcings were taken into account.”
Yep. I read about that yesterday. It confirms what most already knew or suspected. Modeling errors have more to do with the assumed inputs than with the physics. Even primitive models (by today’s standards) yield outputs that match observations closely when given the correct inputs for GHG/aerosol emissions and volcanic activity.

Be careful when you put your coats on, people, in case they make your internal body temperature rise, with fatal consequences. Or on the other hand, if you live in a hot country, and have insulated your house to keep it cooler, make sure that you don’t cause the sun to overheat.
If you don’t want people to think you are stupid, don’t make stupid comments.
That’s effectively what you’re saying. If you think it’s stupid, I agree.
It’s stupid because apparently you don’t realize that the body regulates its temperature, putting a coat on will raise your internal temperature but it won’t kill you.
Why do you keep piling on the straw. You keep attacking arguments no one is making.
Like your sun argument, that’s really stupid.
Maybe it’s best to just say it like it is. Further analogies are not really necessary to demonstrate how stupid your position is:
Your position is simply that in a hypothetical scenario where the only three objects in existence are a heater at 244 K and two passive plates, the passive plates warm the heater to 290 K.
Yes, backed up by experimental evidence and the known laws of physics.
I have actually observed insulation causing a heated object to become warmer, just like the plates.
The temperature warms to 290, but no further, it doesn’t overheat and melt, like your coat analogy killing the wearer, or the house insulation overheating the sun.
You’ve observed insulation making the heat source itself hotter? And a perfectly conducting BB plate is an insulator/heat shield?
Wow…you’ve really seen it all.
Yes, in fact, all matter has some degree of insulation property. And of course a black-body can be a heat shield, the green plates are cooler than the blue plates in the properly solved solution.
That a black-body can be a heat shield is a rather simple concept, yet you continue to fail to grasp that concept.
https://en.m.wikipedia.org/wiki/Heat_shield
“A heat shield is designed to protect an object from overheating by dissipating, reflecting or simply absorbing heat. The term is most often used in reference to exhaust heat management and to systems for dissipation of heat due to friction.“
Try again.
DREMT the quote-bot.
He has no actual undrstanding of what he quotes.
He finds quotes, misunderstands them, misapplies them, takes them out of context, and thinks hes made a point.
Dunning-Kruger supremo.
DREMPTY,
Too bad you did not continue reading
“Heat shields protect structures from extreme temperatures and thermal gradients by two primary mechanisms. Thermal insulation and radiative cooling, which respectively isolate the underlying structure from high external surface temperatures, while emitting heat outwards through thermal radiation.”
Yes, thanks for helping…something that “protects structures from extreme temperatures and thermal gradients” is exactly the opposite of what you need.
You need something that raises the structures temperature, and permanently establishes thermal gradients.
Keep trying.
“A straw man is a form of argument and an informal fallacy based on giving the impression of refuting an opponent’s argument, while actually refuting an argument that was not presented by that opponent. One who engages in this fallacy is said to be “attacking a straw man”.”
“Maybe it’s best to just say it like it is. Further analogies are not really necessary to demonstrate how stupid your position is:
Your position is simply that in a hypothetical scenario where the only three objects in existence are a heater at 244 K and two passive plates, the passive plates warm the heater to 290 K.“
No, that is not quite my position. So this is once again a strawman.
We’ve been through this before, but let’s look at some things that are actually ‘my position’ and then work forward from there.
Let’s assume there is a hypothetical object with blackbody surfaces that contains a power source generating a constant 200 W/m^2 of thermal energy. (The shape does not really matter — it could for example be a sphere of radius 28.2 cm with a 200 W heater or a thin 1m x 1m plate with a 400 W heater.)
1) Suppose the object is placed in an evacuated chamber with the walls held near 0 K (or in deep space @ 2.7 K). “My position” is that the surface of the object will become 244 K.
2) Suppose the walls of the evacuated chamber are warmed to 244 K. “My position” is that the heated object will warm as well — to 290 K in this case.
If you agree so far, we could continue to explore ‘my position’. If you disagree, then tell us what temperatures you would predict for these two cases, and why.
…and just so nobody attacks a straw-man, nobody is saying the blue plate temperature is fixed. All I am saying is that it does not increase in temperature. Not that it can not increase in temperature. It could, but not by adding two passive plates.
You have a situation where the heat source, on its own, comes to 244 K.
You are saying if you add two passive plates, the temperature of the heat source will be 290 K.
That is a temperature increase.
If a heat shield is designed to protect an object from over-heating, it wouldn’t be a great idea for it to lead to an increase in temperature of said object.
Pretty simple, really.
You can try “radiant barriers”, too. That’s already been discussed. Doesn’t do what you need it to.
The two additional plates are not passive, they absorb and emit thermal radiation, causing the center plate to increase in temperature according to the laws of physics.
By “passive” I just mean “not a heat source”. Meaning they can’t warm the heat source.
And, as we’ve discussed, insulation can’t make the heat source warmer. And, the perfectly conducting BB plates are not insulators anyway.
Three statements that are not true.
It doesn’t have to be a heat source to warm the heat source, if it restricts the cooling of the heat source, it will increase in temperature.
Insulation can make the heat source hotter, that’s well known.
Black-bodies, theoretical objects that they are, theoretically can act as insulators, a big near black-body, such as the moon, can cool me during a solar eclipse, that’s what I actually experienced.
Again, three strikes, you’re out.
The only way you can take down the green house effect is to make a big stack of lies.
I’ll just clarify my first paragraph. The passive plates can’t warm the heat source, unless heat flows against a thermal gradient, or unless a thermal gradient establishes itself of its own accord, spontaneously (neither of which are possible). I was not referring to “slowed cooling”, or anything of that nature, there.
“Insulation can make the heat source hotter, that’s well known”
That would be false.
“Black-bodies, theoretical objects that they are, theoretically can act as insulators, a big near black-body, such as the moon, can cool me during a solar eclipse, that’s what I actually experienced.”
There is no “you” in the 3-plate scenario, I’m afraid. By which I mean, there is only the heat source, and the passive plates. For what you experienced, you require heat source (sun), moon, and Earth. Also, I’m pretty sure the moon is not a thin perfectly conducting object.
It’s radiation that flows against the thermal gradient, causing the center plate to increase in temperature, all in accordance with the well established laws of physics, which you seem to ignore.
Just get a textbook on radiant heat transfer.
We have discussed it at length and you are still wrong.
“It’s radiation that flows against the thermal gradient, causing the center plate to increase in temperature”
What you’re describing is heat flow. The clue was the “increase in temperature”. Heat doesn’t flow against the thermal gradient.
Nope, it’s not heat, it’s radiation, I would of thought by now that you would know the difference.
So, I know I have already asked you this and got bumsquat for an answer.
In the 244, 244, 244 solution to the three plate problem, what happens to the radiant energy emitted by the green plates back to the blue plates?
It’s not reflected as in your diagram, because black-bodies do not reflect radiation.
“Nope, it’s not heat, it’s radiation, I would of thought by now that you would know the difference.“
Indeed I do, which is why I said what I said. Re-read until understood.
Right, the thing is, I understand what you posted, and the problem is, that you have it wrong.
You are calling radiation heat flow
“What youre describing is heat flow.”
What I am calling radiation, you are calling heat flow.
Radiation is not heat flow.
You have misunderstood. Try again.
DREMPTY,
Well there is no heat flow in the 244, 244, 244 between the blue and green plates because there is no temperature difference so in your solution you have 400 watts in and 0 watts out, so a failure to follow the first law of thermodynamics.
There has to be a difference in temperature between the plates in order for heat to flow, a net difference in the radiant energy flows in this case.
You still can’t figure out the physics.
Shame you didn’t get it this time. Oh well. Others might.
Too bad I didn’t get it this time is a lie.
You are lying, I get it, it’s wrong.
No temperature difference, no heat transfer, and the radiant heat transfers between the plates will be equal.
244, 244, 244 is wrong and doesn’t follow the laws of physics.
You still haven’t debunked the green plate effect, though I assume in your mind you have.
If you did get it, then it was odd that you wrote those comments demonstrating you didn’t.
DREMPTY,
I have pointed out where in your solution things go wrong.
You don’t respond, you just say things like I don’t get it, or I miss the point etc.
For one, two plates separated, at the same temperature, will not transfer energy or heat between them, which is required for the energy from the heater to transfer out to the ultimate heat sink.
Maybe it’s you who doesn’t get the physics.
Scroll on down, to the bottom of the thread…
1. On the average solar flux S W/m² on the top of a planet’s atmosphere and
2. The planet’s average albedo a.
Those two parameters are not enough to calculate a planet effective temperature. Planet is a celestial body with more major features when calculating planet effective temperature to consider.
The planet-without-atmosphere effective temperature calculating formula has to include all the planet’s major properties and all the characteristic parameters.
3. The sidereal rotation period N rotations/day
4. The thermal property of the surface (the specific heat cp)
5. The planet surface solar irradiation accepting factor Φ (the spherical surface’s primer geometrical quality).
https://www.cristos-vournas.com/
What is “solar irradiation accepting factor” and why is it set at 0.47?
It’s geometry. You must ask the author.
In other words you are offering a theory that you don’t understand.
It’s pretty weird. There’s almost no explanation given on his website from what I can see. And the 0.47 value just appears out of nowhere as well. I’m having a hard time understanding the geometrical reason considering he already does the division by 4 in his formula to normalize TSI to a correct aerial flux and that 0.47 seems random and, quite frankly, tuned.
Well, I did find his “Planet sun reflect” page that attempts to explain it. I’m no closer to understanding what it is though or how 0.47 was determined. If anyone has an idea let me know.
Another puzzle…he calculates T of Venus without an atmosphere of 260K. I’m trying to use his formula and I’m not seeing how gets that value and unfortunately its the one calculation in which he doesn’t show his work. And I’m still no closer to understanding this “solar irradiation accepting factor”.
Why don’t you try commenting there, bdgwx, so you can ask him directly, rather than pointlessly commenting on it here?
And what about this?:

Althought this second publicacin is from 2007 and there are more studies and information about Svenmark’s work as I showed in my two last messages…..
I think this is important for the rise of thunderstorms, especially in North and South America, due to the weakening of the geomagnetic field over these continents.
More waves of arctic air are falling over the Midwest.

If Tim wants to deny the existence and previous discussion of the “3-plate scenario”, and claim that the 244 K…290 K…244 K solution is not what the GPE cult has to defend, then I guess he’s conceding defeat.
I will not play his games.
My ‘game’ is called “physics”. I can’t force you to actually try to understand. I can just try to guide you with simple scenarios and develop mutual agreement and understanding.
The ball is in your court — what temperature do you think the heated object will be in the two scenarios I listed?
a) the heated object will be 290 K if the surroundings are 244 K.
b) the heated object will remain at 244 K as long as the surroundings remain below 244 K.
c) something else??
If Tim wants to deny the existence and previous discussion of the “3-plate scenario”, and claim that the 244 K…290 K…244 K solution is not what the GPE cult has to defend, then I guess he’s conceding defeat.
I will not play his games.
Of course he will not answer your question. When the going gets tough he heads for the exit as fast as his little feet can carry him.
That’s his version of game theory.
The going got tough for Tim, so as usual he tried to start introducing unnecessary complications.
Yes, another of his standard operating procedures is in place.
Divert at all costs.
Maybe fleeing would be your better option.
MikeR’s standard baiting procedures are initiated…and ineffective.
Just simply trying to get you to answer Tim’s question but for some reason (I can hazard a guess) you get out all your avoidance techniques.
I don’t think you are impressing anyone ( with the possible exception of Meh) with your manoeuvres.
MikeR’s standard baiting manoeuvres are continued…and still not effective.
Will try to make it simple, is it A,B or C?
I have a feeling of deja vu.
If Tim wants to deny the existence and previous discussion of the “3-plate scenario”, and claim that the 244 K…290 K…244 K solution is not what the GPE cult has to defend, then I guess he’s conceding defeat.

Ok we are going around in circles again.
So to cut to the chase, this is my effort with regard to the three plate problem
https://i.postimg.cc/J454kTT1/Three-Plates.png
I notice you didn’t comment on that 4 days ago see – http://www.drroyspencer.com/2019/11/climate-extremism-in-the-age-of-disinformation/#comment-411634
You went missing in action. Maybe you missed it. Do you have any specific criticisms of this solution?
This is your effort.
https://www.drroyspencer.com/2019/08/july-2019-was-not-the-warmest-on-record/#comment-374964
It wasn’t well received.
“You went missing in action. Maybe you missed it. Do you have any specific criticisms of this solution?”
Incorrect, MikeR. It’s just that anyone who has followed this discussion from the beginning, or even halfway through, is already well aware of Eli’s math, so the extension to the 3-plate scenario is trivial. In fact, funny story, when JD first introduced the 3-plate thing, they (meaning the GPE cult) actually got the temperature value of the blue plate wrong. I had to correct them on their own math! Oh, how we chuckled.
So, anyway, I had nothing to say about it at the time, that hadn’t already been said. I may have repeated some old arguments further on, but I do get a bit bored repeating stuff that has already been discussed. I know you think that you are very important, but if people stop responding to you, it’s not that they “fled the scene”, or went “missing in action”.
Most likely they’re just bored of you, or realize you’re not really worth wasting their time on.
DReMT,
Thank-you for providing some historical context.
Like you I am getting bored with these exchanges so wading through the annals of the 2 and 3 plate problem is not a number one priority at the moment. However I am glad you and your intimate other enjoyed pointing out the mistakes of others regarding the temperature of the blue plates. The inner dialog must have been remarkable. A real hoot.
Fancy all these so called experts not realizing the blue plate is at 244 K in the presence of the other two plates, remaining at the same temperature as it would in the total absence of neighboring plates.
They didn’t realize it was actually a 1 plate problem! What with their fancy maths. What would they know?
No MikeR, they thought it was more than 290 K!
DReMT. How much more than 290 K? The correct answer is 289.8 K.
345 K.
DReMT,
Yes 345K is obviously wrong, as is 244K.
We all make mistakes and I have been wrong on many occasions, and not being infallible, I am sure that I will be wrong again in the future. A recent example was my very poor choice of words with regard to reflection and back radiation, which you rightly picked up on.
I have been told by many wise man that it’s a sign of emotional maturity when you have the ability to admit when you are wrong and move on. You end getting so much more respect from those who you encounter if you are capable of this. I can’t speak for others, but I would certainly back off and refrain from my harsh criticisms under those circumstances.
Otherwise if you dig in your heels further, then you are likely to be continue to be treated with disdain.
I am hoping that your emotional investment in these long running battles with your numerous foes doesn’t blind you to the possibility of a detente. Think about it.
Try concision.
“A recent example was my very poor choice of words with regard to reflection and back radiation”
Actually, MikeR, one more thing, on that subject…what do you think the temperature of the blue plate would be, in the 3-plate setup, if the green plates were both perfect reflectors?
a) 244 K (GPE debunked)
b) 290 K (a BB plate works the same as a perfect reflector!? GPE debunked)
c) Infinity K (we could have been using mirrors all this time to tap unlimited free energy!? GPE debunked)
OK DREMT,
From your concise response I take it you’re happy to continue to be treated with derision. Fair enough it’s your choice and, as always, I will be happy to oblige your wishes.
I will attempt to be more concise and as the saying goes a picture is worth a thousand words maybe we can approach our little dispute pictorially.
Does this depictions in the link here
https://i.postimg.cc/MZ9DGRbp/three-plates-DREMT.jpg
adequately portray your comments here at
https://www.drroyspencer.com/2019/08/july-2019-was-not-the-warmest-on-record/#comment-374964
Do you have any changes i.e extra green arrows or any other colour that you would like to add?
Please let me know and we can very concise conversation with regard to energy balance equations, particularly with regard to the blue plate.
I promise to make sure that I won’t tax your mathematical abilities.
How will he evade this one? Let me count the ways.
p.s. with regards to your question posed, it is very easy. For infinitely long green plates the eventual temperature at steady state will be infinite. With 400 W in continually and no means for egress of the radiation via the green plates, the answer is obvious, so please no more distractions.
So your answer is c)?
You think after all this time, all we needed for unlimited free energy was just to put some mirrors around a heat source?
They already did the experiments, MikeR, a long time ago. As discussed at this link:
https://principia-scientific.org/light-recycling-disproves-greenhouse-gas-theory/
Yet more diversions! Who would have thought?
DREMT, You have really have no idea, do you. You launch into diversions after diversions because you are incapable of answering the simplest of questions..
All you have to do is simply indicate whether the depiction above corresponds with your version of the 3 plate problem.
If you indicate yes then we can discuss your problem with the blue plate, if no then.please feel free you to suggest amendments that are more in line with your thinking.
To refresh your memory here is the depiction again.
https://i.postimg.cc/MZ9DGRbp/three-plates-DREMT.jpg
Finally, if or when you respond to the above, I would be more than delighted to continue to discuss the other matters you raised.
However please return to the fundamental question . Can DREMT rise to the chsllenge and actually respond appropriately or we just going to get another diversion?
I asked you my question first. You then created a diversion! Amazing…
…as if the stuff you are bringing up hasn’t been discussed a dozen times already…yawn…
I think it was Tim’s a, b and c question and your response, or lack of, was the instigator of the this sub thread, but you may have some other starting point in mind.
Rather than getting bogged down with this diversion why don’t you just respond and clarify your position via
https://i.postimg.cc/MZ9DGRbp/three-plates-DREMT.jpg
I note that you claim you are are getting bored. Rather than responding numerous times over several days with these tedious evasions it would be way less boring if you at least attempted the above. I am an eternal optimist and as unlikely as it sounds, maybe you would learn something.
Can you imagine the thrill? You would have learnt something this year or perhaps this decade and there are still more than 20 days to go. Sounds positively exciting to me, if I was in that position.
I would then be happy to cease these exchanges but if you are happy to continue to be ridiculed then it’s your decision. Maybe you need to resist your masochistic tendencies. Just a suggestion. The ball is in your court.
MikeR continues with his evasion. What will his next diversionary tactic be? Or will he finally flee the scene as fast as his little legs can carry him, as he usually does?
Regarding the GPE ( Greased Pig Experiment), can the porcine contributor continue to weave and evade?
This little piggy does have a sense of humour by accusing me of evasion. On what grounds? Not stated of course.
The only request of his to me we to answer his a,b c question with an emphatic c. As these discussions were invariably based on the original Eli Rabbet source which specified infinitely long 1 dimensional plates ( the complication of view factors were not part of the discussion and 1D so that all emissions were from the sides only) then this was clearly a thought experiment.
So for the case of green plates with mirrored surfaces, as I have already stated, there is no way for energy to leave the system and 400 W is indefinitely continuing to arrive at the blue plate.The steady state solution which would occur after the infinite amount of time to arrive at steady state (or instantaneous if the plate has zero heat capacity) is infinitely hot. If we include some more realistic elements to the problem then we have to specify distances between plates and the size of the plates to calculate a view factor. A view factor of less than one would allow energy to leave the system and the steady state solution would be hot ( for the blue plate with out green plates) but not infinitely hot.
So DREMT , capiche?
Finally there is some good news for you. Your discovery of black bodies that are transparent ( your green plates allow all the energy to pass through) will merit a Nobel Prize in Physics if it can be confirmed experimentally. Maybe you could commission that Hughes fellow to perform the appropriate experiment. However he may still be waiting for his light bulb to explode.
Anyway this another digression. We still await DREMT’s explanation of whether this depiction
https://i.postimg.cc/MZ9DGRbp/three-plates-DREMT.jpg
represents his best attempt at a solution to the 3 plate experiment.
Sure, I capiche that you think there is some way to “produce more power than that being supplied”, that for some reason has not been put into practice.
I capiche that you want to change the subject away from that, desperately.
…and for those taking the c) route, I hope you capiche that there’s follow-up questions to consider…
DREMT aka GP,
As you are pleading the 5th amendement and steadfastly refuse to explain your concept in terms of the clear depiction above, I think it is time to move on.
With regards to the 5th, I should have given you a Miranda Warning at the start of the these exchanges because everything in your comments is highly incriminating. Particularly with respect to your intelligence and emotional over-investment in these debates.
Anyway, what in particular is your objection to answer c? Remember these are thought experiments. Do you really believe that pumping energy indefinitely into a thermally closed system will not cause the temperature of the system, and by extension the blue plate, to increase?
If so then you need more than the 5th amendment. Maybe a psych assessment.
“…steadfastly refuse to explain your concept…”
…for the twentieth time. The first nineteen times I explained it, fine. But I have to draw the line somewhere.
“Anyway, what in particular is your objection to answer c?”
So you now want me to start repeating that, as well?
Look DREMT you are your own worst enemy. If you had just gone quietly no-one would noticed.
Yes, you have refused on 19 or 20 , or who knows how many, occasions, to explain your reasoning using the depiction of the 3 plate setup. This just emphasizes your core incompetencies , such as innumeracy, lack of understanding of basic physics, stubvorn disregard of facts, etc..
I know that you and your mate(s) got teased mercilessly when you tried to explain the Eli Rabbett experiment using a similar depiction,see –
https://postimg.cc/gallery/oyd3w09m/ .
By continuing your charade, I suspect you actually have an agenda to destroy, via guilt by association, the side of the climate change debate that is already doing so poorly in the public and scientific arena.
Your contributions have been invaluable to destroying the credibility of your colleagues and I expect you to keep up your good work. Next please.
MikeR fails at basic reading comprehension…
…I said “the first nineteen times I explained it, fine. But I have to draw the line somewhere.”
What you are bringing up, the input and outputs from each plate, etc, has been discussed many, many times before, as you well know. Whereas I have introduced something new to the 3-plate discussion, which is “what happens when the green plates are perfect reflectors?”. As soon as I introduced that, you then immediately brought up your diversion back to previous discussions.
You are the one being evasive. As we can see down-thread, the question is causing Team GPE all sorts of problems. So it’s understandable that you’re so desperate to draw attention away from it.
DREMT, even you admitted your original question was ill-posed and you tried to clarify your position. You can hardly blame me for also finding your statement ill-posed and trying to clarify.
Why are you afraid to engage?
1) The “blue plate” by itself with 0 K (or 2.7 K) surroundings, black body surfaces, and a fixed 200 W/m^2 heater will settle at 244 K. You seem to agree with that.
2) The same blue plate with warmer surroundings will be warmer than 244 K. For some reason you can’t seem to admit to this.
If we can’t agree on basics, then there is no way we will progress to understanding more complex situations.
If Tim wants to deny the existence and previous discussion of the “3-plate scenario”, and claim that the 244 K…290 K…244 K solution is not what the GPE cult has to defend, then I guess he’s conceding defeat.
I will not play his games.
I am not denying any previous discussion — merely clarifying the central point. If nothing else, not everyone has followed every line of previous discussion.
Here is the core of the issue — a very straightforward physics problem.
We agree the answer for P/A = 200 W/m^2 and T(C) = 0 K will be 244 K.
I propose for P/A = 200 W/m^2 and T(C) = 244 K, the answer will be 290 K.
Tim…you called a correct summary of the position that the GPE cult has to defend, a “straw man” (meanwhile other cult members have continued to defend it, because it is a correct summary). You then tried to change the setup to include walls, etc.
That is tacit acknowledgement that your position is untenable.
You can either:
1) Apologize for wrongly suggesting it was a straw man, and join the others in defending the indefensible.
2) Directly and openly concede that your position is untenable.
Any other response from you will result in a redirect to this comment, until such time as you either take option 1) or 2), or stop responding to me.
Thank you for your co-operation.
DREMT, you claimed: “Be careful when you put your coats on, people, in case they make your internal body temperature rise, with fatal consequences. Or on the other hand, if you live in a hot country, and have insulated your house to keep it cooler, make sure that you don’t cause the sun to overheat.”
These are strawman arguments. This is not even CLOSE to what any scientist claims. If you think you are accurately describing what a scientist claims, then please link us to a scientist saying anything like this.
More directly to the topic at hand, you claimed: “Your position is simply that in a hypothetical scenario where the only three objects in existence are a heater at 244 K and two passive plates, the passive plates warm the heater to 290 K.”
This is much better, but still flawed. First was the error you yourself later corrected — we don’t have “a heater at 244 K” but rather “a heater at 200 W/m^2”. There is also the semantic issue of whether the passive plates ‘warm’ the heater above 224 K, or if the active heat source ‘warms’ the heater.
If we agree that:
1) you really meant “a fixed power heater” rather than “a fixed temperature heater”
2) we are not going to quibble about semantics ascribing a single cause to the possible temperature change when multiple factors are involved,
then I will agree that your summary is accurate.
******************************************
Will you agree that
P = (sigma) A [T(h)^4 – T(c)^4]
is an accurate equation for the power transferred from a blackbody surface of area A @ temperature T(h) to surroundings at temperature T(c)?
http://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-413236
By the way, Tim:
“These are strawman arguments. This is not even CLOSE to what any scientist claims.”
Yes…that’s kind of the point. I was ridiculing the position you have to defend, Tim. Those arguments are as stupid as what you have to defend.
You are a clown, defending a ridiculous position. Just making sure we are on the same page. Obviously I did not mean those comparisons were the summary of your position, though.
Now, you can respond with:
“1) I apologize.”
or
“2) I concede”.
Those are the options. No other words in your response.
Or we’re back to the redirect.
DREMT, in case you haven’t made the connection, the “passive plates” of the “green plate experiment” are “walls” that comprise the “surroundings” for the “heater”. Without the “green plates, the surroundings are “the 2.7 K universe”. MY scenario is NOT a change or diversion — merely a restatement with clear, neutral language.
Again, rather than starting with a conclusion or starting with semantics or starting with what you THINK other people are saying, let’s start with what we agree on. Rather than expecting me to defend everything any one might have said (or that you imagine they might have said), let’s try the basic science and see if we can defend our OWN positions.
***********************************************
Will you agree that
P = (sigma) A [T(h)^4 T(c)^4]
is an accurate equation for the power transferred from a blackbody surface of area A @ temperature T(h) to surroundings at temperature T(c)?
Will you agree this can be rearranged with simple algebra to give
T(h) = [ P/(sigma*A) + T(c)^4 ] ^(1/4)
as the steady-state temperature of the heated object?
If not, what equation(s) would YOU use to calculate such a thing?

(Just in case anyone can’t see through Tim’s sophistry; unlike the green plates, his “walls” were at a fixed temperature, and then “warmed”…so he was changing the conditions of the thought experiment and!adding an additional heat source to complicate matters and try to intentionally deceive)
What we are defending in regards to the green plate effect are the First Law of Thermodynamics and the Stephan-Boltzmann law
https://en.wikipedia.org/wiki/First_law_of_thermodynamics
https://en.wikipedia.org/wiki/Stefan%E2%80%93Boltzmann_law
That’s what you are up against DREMPTY.
Propose a solution that follow both of those.
244, 244, 244 violates both of them.
For those who can’t see, DREMT refuses to engage in science and math and calculations. When he is ready to actually defend his position and to actually critique my position, then we might make some progress.
Those following closely will know the science, math and calculations have already been laid out.
They will also see through the likes of Dim and Blob.
One would think that when one separates the plates and the energy transfer changes from conduction to radiation, that the temperatures and energy flows would change.
One would think that you would finally just acknowledge that the Green Plate Effect is debunked.
DREMPTY,
Your solution doesn’t debunk the green plate effect, because it’s wrong.
I’ll wait until you actually post something that does debunk anything.
Well, at least you acknowledge the existence of the solution now…that’s progress.
As ever, when faced with a clarifying fact question, as Tim clearly stated it, DReMT finds a way to evade answering.
He is not the least bit interested in getting at the facts.
“The same blue plate with warmer surroundings will be warmer than 244 K. For some reason you can’t seem to admit to this.
If we can’t agree on basics, then there is no way we will progress to understanding more complex situations.”
The blue plate is the only heat source in the 3-plate scenario. The surroundings are a perfect vacuum with no additional heat source, anywhere. So if you start talking about “warmer surroundings” you are introducing an additional heat source, somewhere, like with his heated walls. So Tim has it exactly backwards. He is trying to introduce a more complex situation than the extremely basic 3-plate scenario, in order to confuse matters. There’s no “progressing to understand more complex situations”, as he puts it…it would be “starting with more complex situations and regressing to understand more basic ones”.
That’s why it’s always best to avoid these sophists’ games. Just a little advice for anyone reading.
“The blue plate is the only heat source in the 3-plate scenario. The surroundings are a perfect vacuum with no additional heat source, anywhere.”
The surroundings of the Blue are space at 0 K, OR GREEN plates at 244 K.
It matters not a bit to the RHTE how the surfaces attained their temperature.
Thats the POINT.
“That’s why it’s always best to avoid these sophists’ games. Just a little advice for anyone reading.”
It’s good advice, too, people! Make sure you take note.
If DREMT thinks our science is sophistry, that we are using it to try to fool people, then clearly he is unable to recognise or comprehend what is simply basic physics.
Too bad.
I really can’t stress that enough: Make sure you take note! They will try all sorts of things, so you have to be wary of them. There are some who even try to take advantage of the fact you’re not responding to them. Look out for these ones, they’re especially desperate and pathetic.
“take advantage of the fact youre not responding to them.”
Hilarious.
I send you some interesting extracts of my first link before to know your opinion please! (beacause it’s long….)
https://public.wmo.int/es/resources/bulletin/observacio%CC%81n-del-vapor-de-agua
” Recent analyzes suggest that the warming of the earth’s surface may be sensitive to changes in volume in the water vapor of the order of subparts per million (ppm) in the low stratosphere. Research has found that the 10% reduction in stratospheric water vapor between 2000 and 2009 acted by decreasing the rate of increase in global surface temperature in this period by 25% compared to what would have happened due to only to CO2 and other greenhouse gases8.’
“In the absence of three-dimensional global observations of water vapor, global reanalysis products are frequently used to validate simulations of numerical models. Two of the most widely used reanalysis data sets are the Retrospective Analysis in the modern era for NASA research and application (MERRA), with its new release, the MERRA2, and the Provisional Reanalysis of the European Center for Medium Weather Forecasting term (CEPMMP)”.
“A recent study concluded that the reanalysis differed considerably from MLS observations by overestimating the global average annual water vapor in the high troposphere by around 150%. Vertically, the transport of water vapor through the tropical tropopause (16-20 km) in the reanalysis is faster, around ~ 86%, compared to the MSL observations. In the low tropical stratosphere (21-25 km), the average vertical transport according to CEPMMP is 168% faster than that estimated by MLS,”
(Note:
MSL: Microwave Limbo Probe Instrument. Limbo sounding: the technique of probing several layers of the atmosphere through observation along a tangent beam that does not intersect the earth’s surface)
“The models used to predict the climate of the future make use of reanalysis data to verify the correct simulation of the current climate. Therefore, the lack of accurate water vapor data in the important region of the high troposphere and low stratosphere will limit the ability of these models to predict the climate of the future.”
“The global distribution of water vapor in the high troposphere and low stratosphere is not well known due to the shortage of observations with high vertical resolution in these regions of the atmosphere. In some cases there are even large discrepancies between satellite data, frost point hygrometer data and meteorological reanalysis. More accurate data with greater geographic coverage is needed. The temporal trends observed in stratospheric water vapor are vaguely understood, demonstrating a lack of knowledge about how water vapor enters the stratosphere. These are areas of study to which the VAG will be dedicated in the future.”

An interesting extract too from this AGU100’s article:
Overview of the Earth’s Climate System
]The principal source of energy that drives the dynamics of Earth’s outer spheres, including its climate, is unquestionably the Sun, and it is electromagnetic radiation that overwhelmingly dominates energy exchange between the Earth and its cosmic environment [Kandel and Viollier, 2005]. At a radiative balance of 235 W m−2the Earth would have an average surface temperature of only −19C, resulting in a perpetually frozen planet [Ruddiman, 2001]. Fortunately, the planetary atmosphere traps sufficient long‐wave energy reradiated by the warm Earth’s surface (natural greenhouse effect) to raise the surface temperature by about 33C to a more hospitable average of 14C. This natural greenhouse effect is overwhelmingly due to water vapor [Chahine, 1992], the principal greenhouse gas, and only to a lesser degree due to the other greenhouse gases, such as CO2, CH4, N2O, and CFCs. Nevertheless, the anthropogenic addition of CO2since the advent of the Industrial Revolution is believed to have enhanced the global energy balance by approximately 1.5 W m−2, with a compound anthropogenic greenhouse effect of about 2.4 W m−2[Ramaswamy et al., 2001], yet satellite data for the last decade suggest that a decline in the cloud albedo alone could account for a 26 W m−2enhancement of the short‐wave solar energy input into the system [Pall et al., 2005]. Thus the current scientific and political dispute ultimately boils down to the following: is the additional energy of 2.5 W m−2that is responsible for the centennial temperature rise of 0.6C [Houghton et al., 2001] due principally to greenhouse gases or is it due to some external factor, such as the Sun?
[3]Presently, 0.2C of the rise in temperature over the 20th century is attributed to the observed increase in solar brightness, with the anthropogenic greenhouse effect (0.4C) related to an increase of anthropogenic greenhouse gases, principally CO2, in the atmosphere [Mitchell et al., 2001]. The attribution of only one third of the centennial temperature increase to solar forcing, despite a good correlation with solar indices [Kristjnsson et al., 2002;Valev, 2006], is based on the empirical observation that, averaged over the 11‐year solar cycle, the variability in Total Solar Irradiance is only 0.1% (less than 1.5 W m−2) [Lean, 2005]. An amplifier related to solar dynamics would therefore be required to explain the entire magnitude of the trend. The impact of ultraviolet radiation on ozone and stratospheric dynamics [Reid, 2000] and/or galactic cosmic rays (GCR) [Marsh and Svensmark, 2003] were briefly considered to be such amplifiers, but were dismissed because of the lack of understanding of physical processes, particularly cloud formation, that could point to a climate connection [Ramaswamy et al., 2001]. Note that in regards to the Earth’s radiative heat balance we are not dealing with mutually exclusive scenarios, as climate models respond in a similar way to the addition of energy from any source and it is only the relative importance of these potential drivers at a variety of timescales that is the contentious issue. Note also that compared to the sizes of the global energy fluxes, and their compound uncertainty (on the order of 6 W m−2), the apparent centennial to annual trends are at the limit of detectability [Kandel and Viollier, 2005]. It is therefore not likely that the issue of principal climate driver(s) can be resolved by energy balance considerations. Instead, observations based on past climate trends observed over a variety of time/space scales and their compatibility with the celestial versus greenhouse gas records may help to resolve their relative contributions.
[4]A spate of recent empirical observations [Scherer et al., 2006, pp. 427448, and references therein] demonstrates that the sun‐climate connection is apparent in a plethora of high‐fidelity climate indicators [Lean, 2005] and, as summarized in the Hadley Centre for Climate Prediction and Research review ofGray et al.[2005], the detection/attribution assessments of climate models suggest that the solar influence on climate is greater than would be anticipated from radiative forcing estimates. This implies that either the radiative forcing is underestimated or there are some processes inadequately represented in those models. If so, climate modulation by indirect amplifying mechanisms, such as GCR, may play an important role. The most likely pathway for translation of the high‐energy particle flux into a climate forcing variable involves the role of clouds [Svensmark et al., 2006;Vieira and da Silva, 2006;Perry, 2007]. In recognition of the potential importance of GCR on clouds, a multiyear experimental program to quantify this process has recently been initiated by European Organization for Nuclear Research (CERN) [Arnold et al., 2004;Kanipe, 2006].
[5]Considering that solar radiation reflected by clouds and the atmosphere accounts for approximately 77 W m−2and that evapotranspiration and precipitation each account for 78 W m−2[Baede et al., 2001;Stocker et al., 2001], even a minor change in cloudiness could potentially alter the planetary energy balance by more than the disputed 1.5 (or 2.4) W m−2, particularly if the highly effective but contentious role of aerosols (terrestrial and/or GCR generated) is taken into account. In this context, the pattern of dominant energy flow in the planetary system could be viewed from the top‐down (Figure 1), instead of bottom‐up, thus permitting celestial phenomena to act as the principal (yet not the sole) climate driver over shorter time periods (decades to millennia) as it does over geological time periods. In such a scenario, the relatively small carbon cycle would have to be considered as being superimposed (i.e., piggybacking) on the much larger water cycle instead of driving it. That this may be the case is indicated by the observed coincidence of the South African hydrologic regime [Alexander, 2005] and the Southeast Asian monsoon patterns with the record of past solar variability [Bhattacharyya and Narasimha, 2005]. In another example, the overall centennial increase in precipitation over the conterminous U.S. coincides with enhanced solar intensity and most of the inter‐annual minima in precipitation coincide with the minima in solar intensity (Figure 2). Regardless of the actual mechanism involved, causation between these terrestrial cycles and solar radiation can only be from the Sun to the Earth, pointing to solar activity as the principal driver of the global water cycle, including moisture advection from the tropics to higher latitudes and the flux of water vapor from the terrestrial biosphere.

MikeR,
Your chart of HADSTT3 vs UAH and HADSTT3 vs RSS demonstrates the same bias in trend that I see. You are focusing on the volatility of the month to month readings and looking at that as a measure of accuracy when you should be looking to the trend.
having trouble posting… MikeR
The upper atmosphere is cooling. It makes no sense that the lower troposphere should warm more than the ocean with a cooling stratosphere. I can say without a doubt that the atmosphere is not the primary store for energy gain and loss of the system. Its the ocean. You can see that the atmosphere follows the ocean currents.
As you could see from my study, HADSTT3-UAH has a tiny positive slope, meaning the oceans are warming slightly faster than the atmosphere. That makes sense as the stratosphere is colder.
Anyways… I appreciate the fact that you appreciate the fact that I actually look at data. I have to say that I believe I make a very good case for my side, in particular, the AMO cycle being responsible for the 1980-2016 trend. If in 25 years the AMO doesn’t drop in spite of a GSM, I guess I will have to concede… either that or start blaming the magnetic reversal. I honestly do not think that will happen. Also, I don’t think a warmer earth is that bad. You get more rain, and a green Sahara. Storms are not increasing in intensity. Sea level rise is linear. That hasnt changed. You might want to stop by my facebook at least look at the evidence for the GSM just in case we are right so you don’t get caught off guard by it.
Sea level rise is most definitely NOT linear.
People who make that claim wither cherry pick gauges (Cuxhavn being the favorite), or they believe they are capable of seeing an accelerating trend by eyeballing a graph of noisy data without doing the number work.
Midas,
I’ve reviewed dozens of tide gage charts and they all say the same thing. The rate of change in sea level has not changed at all. Even if you could prove that more sea level readings are outside of a standard deviation, the change is so small that on a % basis, the natural trend is still at least 95% responsible for the changes in sea level rise. So false blame is being place on humans. You could cut Co2 100% and it would make no difference. Sea level would keep rising causing us to regulate new construction on the coasts.
So you are claiming that not one tide gauge shows acceleration?
An all-encompassing statement like that enables be to cherry pick just one counter-example for debunking.
Try Klaipeda:
1900s average to 1950s average: a rise of 56 mm
1950s average to 2000s average: a rise of 136 mm
‘be’ = ‘me’
Midas I didnt say all. I said Ive reviewed dozens. You cant pick 1 to disprove.
Anyways, hilarious that you picked that location as your cherry pick example. First of all, there are TONS of gaps in this dataset. The normal volatility of sea level here is very substantial like 1 full meter. Missing data could alter the trend. Have you noticed that? How do we know the gage wasn’t moved during one of these gaps? I’m showing the last reading there was 11 months ago, was 6.399. Since early 2007, sea level has dropped from 7.119 to present value. They stopped recording there it looks like, so no way to check how far that down trend went.
Also… check 1976… it was the lowest reading of the whole dataset. So for almost 80 years the trend was lower to flat. There is no rise here at all.
Sometime between 1976 and 1990, there appears to have been a datum shift because after that shift, the data looks flat lined again. Just because NOAA didnt identify the datum shift on this dataset doesnt mean it didnt happen. And dont try to tell me that sea level around the world spiked during that time because obviously that isnt accurate. Other locations maintained their linear trends. That is obviously a local event. Actually, just across the Baltic sea, sea level is dropping. What you have in this location is isostatic rebound. Areas very near the rebound typically sink… almost like the other side of a seesaw.
For some reason I can’t post the link for the noaa tides and currents. You will have to do a search for it.
Following in the acceleration (in mm/yr/century) in gauges which:
(i) operated for at least 100 years
(ii) have not had their data flagged
The acceleration is based on quadratic regression.
I was having trouble posting this, so I have used station numbers instead of names. The numbers are from the PSMSL. NOAA gets their data from them, but chooses to apply their own station numbers and their own inconsistent baselines (damn yanks).

Yes Scott with your reference to the cooling stratosphere, I think you have nailed it. The degree of stratospheric and upper tropospheric contamination of UAH is the most likely reason why UAH performs so much more poorly than RSS. Particularly with respect to post 2002 SST measurements in absolute terms, see again –
https://i.postimg.cc/2ysFkQS1/Comparison-UAH-RSS-SST3-02-until-present.jpg
It is clear that the sampling of the stratosphere and upper troposphere makes satellite measurements, even in the absence of SSW events, poor proxies for the surface temperatures, including the ocean.
As for the differences between the two satellite measurements, UAH is more severely affected by this than RSS, see the discussion starting here at –
http://www.drroyspencer.com/2019/04/uah-global-temperature-update-for-march-2019-0-34-deg-c/#comment-348328
As a consequence, RSS follows monthly changes in of ocean temperatures better than does UAH and therefore correlates better, presumably being due to being less affected by the transient events higher up in the atmosphere.
The only measure where UAH performs significantly better than RSS is for the overall trend . The trend for SST is since 1979 is 0.137 C per decade while for UAH it is 0.112 and RSS it is 0.181. It is easy to understand why UAH , again in terms of of contamination, would be lower than SST but why RSS is so much larger is more difficult to explain. It could be real and the lowest parts of the troposphere are warming more rapidly than the sea surface while higher up, where UAH is biased to, the temperatures are rising more slowly. But who knows? Maybe someone familiar with ship based balloon radiosonde measurements could advise?
So all we know is that in terms of three metrics, RSS is significantly better for two and significantly worse for one. A bit of a line ball really.
Scott, once again it is a pleasure to exchange comments with you. It is such a contrast to dealing with some others who are less numerate.
Scott,
With regard to you AMO coming to the rescue., I am not sure I would be putting too many eggs in that basket. You have pointed out that the AMO peaked sometime in 2010, but it is a very noisy signal and so hard to judge the maximum. I would not put too much emphasis on the single point.
Using the entire data set seems more sensible.
Here is a low pass Fourier filtered version of the AMO data (with a cut ff frequency corresponding to 54 years). In this case the maximum appears to be at about 2009.
https://i.postimg.cc/7LCRD9T7/AMO-Fourier-Filtered.jpg
Unfortunately because of the limited number of AMO cycles the Fourier method may not be the that appropriate.
Maybe a better solution is to use a Loess filter For a filter of 60 years duration then you get the following –
https://i.postimg.cc/pdg6djDS/AMO-Loess-Filtered.jpg
This is a bit worrisome for those banking on an imminent drop in the AMO. Accordingly Scott, you might have to look elsewhere for your savior. Maybe the PDO , a drop in solar irradiance or perhaps that sudden magnetic reversal.
On the latter there hasn’t been a reversal for 780,000 years so maybe we are due for one. Keep on hoping.
Mike R,
I’m definitely NOT hoping for a magnetic reversal. lol
I actually believe that the AMO is made of 2 component waves at 61 years and 84 years. It is most likely solar forced either by the movement of the sun around the barycenter or the planets causing changes in solar output thru their gravitational or magnetic connections. My home town tracks the AMO without fail. I have no reason to think that this cycle won’t continue. I do leave room for man made influences stacked on top of this cycle. The amplitude of our influences has been grossly overestimated due to the fact that the AMO is so poorly understood.
https://www.facebook.com/reddformula350/posts/2782656818420190
Scott,
It is interesting, but not that surprising, that temperatures on the East coast of the US would track temperatures in the North Atlantic. Maybe they have something in common?
Is this a global trend? Does the rest of the world also have to follow trends in the US?
I will look for evidence that the East coast of Australia also follows the North Atlantic? Failing that I might see whether the East coast of Australia follows the temperatures in the Western Pacific? I think that might be more productive.

Follow-up question…
In the 3-plate scenario, what is the temperature of the blue plate when the green plates have 50% reflectivity?
DREMPTY,
Why pose a more difficult problem when you can’t correctly solve the original one?
That’s exactly what I should have said to Tim…thanks, I’ll remember that one.
DRsEMT continues to post nonsense. DRsEMT wrote:
No body has claimed that the Green plate (assumed to be a BB) acts that way. That would be your “c” situation. If the Blue plate were a perfect reflector, it couldn’t emit any IR EM radiation. More red herrings from DRsEMT. Your efforts are just another round of BS like your “magic” green arrows from the Blue plate toward the Green.
That you continue to ignore reality makes you to be the fool, or worse, someone intent on spreading disinformation.
We were talking about if both green plates were perfect reflectors, Swanson. Not the blue plate. Try again.
DRsEMT, There’s no point in trying again as you will simply post more delusional physics in reply. For example, answer “c” would be appropriate, except that your conclusion of an infinite temperature and unlimited power supply is bogus, since the Blue plate would melt and there’s no way to produce more power than that being supplied. Just another red herring from a troll.
“…and there’s no way to produce more power than that being supplied…”
Yes, you’re in a pickle really, aren’t you? You know it can’t be c), you’ve already shown that you don’t like b), so that only really leaves a)…
…then again, all of the options debunk the GPE, so…
DRsEMT, You left out the best option: NONE OF THE ABOVE.
In which case, you still need to have an answer…
The intelligent will have worked out by now, thinking through the answer to my follow-up question…that the Green Plate Effect is debunked.
Yes, DREMT you must be wondering what has happened to the intelligensia? Seems no one is rushing to your defence. I guess you are on your lonesome with this one.
Maybe call in the clowns, or failing that, the sock puppets.
People can read, and think, and work it all out. They don’t need to comment. Personally, I’m just enjoying the moment.
I’m also noting the lack of answers from all of the GPE gang. Funny that.
DReMT,
The following contributors seem to have engaged with you regarding your somewhat unique interprwtation of the GPE.
Nate, Tim Folkerts, Bobdroege, E.Swanson and myself in this comments section alone.
You in contrast are on your own after your only cheerleader left abruptly after being asked to justify, using his own work, his support of your interpretation.
I am however glad your enjoy social isolation, ensconced in your foxhole. It could explain why you have generated some 224 comments here and in the preceding comments section. You have left me in your wake as I sometimes have to attend to ablutions and other matters of personal hygiene. Maybe it’s time you did likewise.
Sorry to be so snarky, but you bring out the worst in me and I have offered you a truce on many occasions.
You play your mind games, I have a good laugh at you. I think we work well together.
MikeR says:
“Nate, Tim Folkerts, Bobdroege, E.Swanson and myself in this comments section alone.”
Can I qualify by noting that DREMT has agreed:
1) Green plate heat input from blue plate is 0 W.
2) Green plate heat output is 200 W.
How can the green plate maintain its temperature when it is losing heat? The explanation according to DREMT is that this arithmetic is disallowed in this particular application of physics.
Have I got that right DREMT?
Svante’s here to try to change the subject.
http://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-413357
a), b) or c), Svante?
Or do you have a different option?
c) but as soon as you tap it your perfect reflection is gone.
Can’t be c), Svante. To quote Swanson, “…there’s no way to produce more power than that being supplied”. If there were, all the world’s energy problems could have been solved by now.
You’re going to have to give it another go.
I’ll go with b, but your conclusion that that means that a black-body is a perfect reflector is perfectly incorrect, try again.
Absorp.tion and re-emission is what is going on.
Still no debunking to be found.
Dr Roys Emergency Moderation Team says:
Output > input means rising temperature, and vice versa.
Except for your blue plates of course.
Try again …
Output > input means falling temperature, except for your green plates.
So in the long run you can tap the same as the input without reaching 0 K.
Except for your green plates which keep on giving with zero input.
Svante ignores Swanson, and apparently believes you can produce more power than that being supplied…despite the fact that if this was the case we would already be using reflective surfaces around heat sources to exploit that free extra power.
Blob is at least being a bit more sensible, in going for option b) – though technically he is also ignoring Swanson’s words – but blob makes the decision that if the two green plates were perfect reflectors, the temperature of the blue plate would rise to 290 K, the same temperature he believes it would be if the green plates were black-bodies. The problem with that is, Team GPE have long argued the green plates are insulators for the blue. So he is saying a perfect reflector is no better an insulator than a black-body!
Dr Roys Emergency Moderation Team says:
How does that follow from:
And how can you tap anything without disrupting your all around perfect reflection?
DREMT, how do you think you can tap anything without disrupting your perfect reflection?
No DREMPTY,
I only picked b because it shows you mis-understanding of what black-bodies and insulators are.
It goes through 290 on its way to melting.
400 watts in and nothing out, since watts are joules per second, the temperature keeps going up.
Dr Roys Emergency Moderation Team says:
How does that follow from:
And how do you think you can tap anything without disrupting your perfect reflection?
DREMPTY,
I picked b, because it was the highest temperature, as there is no such thing as infinity K.
And you could not get unlimited power from that as you can only get out what you put in, namely 400 watts.
There is no correct answer.
Dr Roys Emergency Moderation Team says:
How does that follow from:
And how do you think you can tap anything without detracting from your perfect reflection?
How do you think you can tap anything without detracting from your perfect reflection?
Dr Roys Emergency Moderation Team says:
How does that follow from what I said:
“you can tap the same as the input”
And how do you think you can tap anything without detracting from your perfect reflection?
blob, thank you for your assistance.
Svante, you can argue it out with Swanson.
Looks like Tim and MikeR also said c).
Swanson said the the plates would melt, that’s not a bad answer.
I’ll try mentioning it to you, since Tim is avoiding the issue:
“So in the long run you can tap the same as the input without reaching 0 K.”
If you input 400 W and tap out 400 W, that leaves you with no power to raise your blue plate above 0 K.
Swanson ran off after accidentally spilling the beans.
And Svante, insulation does not increase the temperature of the actual heat source. Once again this is all just an extended demonstration of the lengths these people are willing to go to, to defend this nonsense.
Dr Roys Emergency Moderation Team says:
1) No, power equilibrium means steady temperature.
2) Power surplus means rising temperature.
3) Power deficit means sinking temperature.
Wrong, increasing insulation means power surplus.
That’s case 2).
No, Svante…there is no power to establish a temperature in the first place. 400 W – 400 W = 0 W.
Insulation does not increase the temperature of the heat source. Consider an electric heater in your house. No complications with thermostats or anything else. Adding insulation to your home does not make the heating element within that heater warmer. Adding the casing around the heating element does not warm the element via back-radiation or reflection. You guys think a black-body can double the output from the element, and a material with emissivity 0.5 can quadruple it! Your devotion to Eli’s math does not tally with real-life experiences. Wake up.
I observe we have DREMT trying to tell Svante a 400W incandescent light bulb at equilibrium has no power “to establish a temperature in the first place”, insulating our house has no effect on temperature “within”, an added shield does not “warm the element”, and devotion to proper 1LOT math “does not tally with real-life experiences.”
Wake up DREMT. As Tim would write, DREMT is at the limit where his credibility has gone to zero.
(I assume everybody can see through Ball4 by now)
Bad assumption DREMT.
Many, including Dr. Spencer, have done the proper experiments to see thru your brand of sophistry & prove your credibility in this field to be in the limit zero.

Dr Roys Emergency Moderation Team says:
It doesn’t, and neither did I.
Increasing insulation means power surplus.
Power surplus means increasing temperature, doesn’t it?
“It doesn’t, and neither did I”
Team GPE is indeed arguing that insulation can increase the output from a heat source.
x 2 if the insulating material is a black-body, emissivity = 1.
x 4 if the insulating material has emissivity = 0.5.
x infinity if the insulating material has emissivity = 0.
I’m afraid that is what Team GPE has to defend.
Read the links, don’t read the links, try to understand, try not to understand. That is your choice, Svante. I can’t force you to do it, you have to make a conscious decision to try.
“insulation can increase the output from a heat source.”
No DREMT. That takes more fuel. Added insulation to your home economizes on fuel.
Try to make a conscious decision to understand the physics of added insulation, the physics of a 400W incandescent light bulb, and a heat shield. I recommend actually passing & commenting based on a college 1st course in thermodynamics in your honest attempt.
Ball4 quotes me, where I correctly summarized Team GPE’s position by saying:
“insulation can increase the output from a heat source.”
and responds:
“No DREMT.”
Thank you, Ball4. I’m glad you agree with me, and disagree with Team GPE.
Aha, the good old one way radiation vs. heat confusion?
A steady heat output will do DREMT, lets say 400 W.
Reduce the loss rate by 1 W and the heater temperature must rise until the loss rate is back at 400W.
It’s very difficult to understand, isn’t it?
“Aha, the good old one way radiation vs. heat confusion?”
No.
Choose to understand, or don’t. Up to you.
The word “No” that I used means I disagreed with you DREMT which is usually the case. IF DREMT ever gets the physics of atm. thermodynamics right, THEN I will agree with DREMT.
You disagreed with a statement I also disagree with, a summary of Team GPE’s position:
“insulation can increase the output from a heat source.”
That’s what they are arguing. You and I disagree. I appreciate your help.
Perhaps if you could answer a few simple questions and refrain from adding anything extra.
1) Green plate temperature is stable only if its heat input from blue equals its heat output to space, right?
So now DREMT disagrees with DREMT’s own written statement. DREMT twists in the wind of comments with no basic understanding of, nor grounding in, thermodynamics for certain systems as I wrote.
“So now DREMT disagrees with DREMT’s own written statement”
That’s right, Ball4. I wrote a statement summarizing what we can see Team GPE arguing here and elsewhere, and both you and I agree they are wrong. It’s not difficult to understand if you possess basic reading comprehension skills.
Ball4, is he confusing temperature [K] and power [W]?
That would explain his earlier statement that high temperature would solve “all the world’s energy problems”.
There’s the unbelievable depths that the others will sink to…
…and then…way, way down…there’s Svante.
Then DREMT 1:41pm ought to make use of basic reading skills: I do not disagree anyone else is right or wrong, I disagreed with DREMT 10:50am.
—-
Svante 2:36pm, I observe DREMT confuses many things in the field of thermodynamics. Here I observe it appears DREMT confuses his term “output” with “temperature” term used by others due DREMT’s poor comprehension in this field.
…and “temperature” is related to radiative “output” via the SB Law. Yes, that is radiative flux, W/m^2, but the areas of the surfaces discussed in the GPE are constant, and so power (watts) has been used by both sides of this argument at various points to describe energy flows.
Ball4, you and I both agree that this statement:
“insulation can increase the output from a heat source.”
is wrong. That is what Team GPE is arguing.
Dr Roys Emergency Moderation Team says:
You really do mix up radiative output with heat output.
The latter depends on surrounding temperature.
If there is no temperature difference there is no heat transfer, regardless of the absolute temperature.
Gee.
Incorrect, Svante, I don’t mix up anything. An object radiates based on its temperature, emissivity, and surface area, regardless of the temperature of its surroundings.
DREMT “I don’t mix up anything”
DREMT 4:20pm writes: “Insulation does not increase the temperature of the heat source.”
DREMT 9:51pm writes: “insulation can increase the output from a heat source.”
DREMT mixes up temperature & output.
…and yet he also explains how they are connected…
Then don’t mix them up again.
You’re ridiculous.
DREMT 3:12pm: Then show me where Team GPE (DREMT term) or anyone else besides DREMT has argued in comments on this blog: “insulation can increase the output from a heat source.” Those are alone DREMT’s incorrect (and confusing) words.
—-
Svante 3:55pm, you are showing use of the heat term confuses DREMT (and many others). As I have long held, drop the heat term and end this confusion. The term is NEVER needed in thermodynamics.
Improvement in your comment eliminating confusion:
If there is no temperature difference there is no net energy transfer, regardless of the absolute temperature.
By Planck’s law with measured emissivity added, there is still gross energy transfer but IN net of OUT energy transfer is zero in the case of no difference in temperature and measured emissivity.
If there IS a temperature difference in objects of the same emissivity, the sign convention used to compute q will show the net energy transfer direction.
Train yourself not to use the heat term and your energy transfer comments will cease to incite riots.
Sure, Ball4, no problem:

MikeR said, quoting me (where once again I was stressing the absurdity of the position Team GPE has to defend): “Radiative insulation by a black-body material means you can double the output from a heat source, and with a material at emissivity 0.5 you can quadruple it.”
And he responded:
“Yes correct.In terms of temperature, for a theoretical blackbody insulator the temperature increase is 19% while for an emissivity 0.5 the increase is 41%”

“Insulation can make the heat source hotter, that’s well known.“
Again, those are your incorrect words not MikeR’s as you admit MikeR was quoting YOU DREMT.
Actually MikeR: “the function that describes the temperature…In terms of temperature…”
Neither does bobdroege use the words “insulation can increase the output from a heat source.”

“Nope I’m good, insulation makes the heat source warmer. I win, you are losing.”
I hope three examples will suffice.
“Again, those are your incorrect words not MikeR’s as you admit MikeR was quoting YOU DREMT.“
That’s right, Ball4. MikeR said, quoting me (where once again I was stressing the absurdity of the position Team GPE has to defend): “Radiative insulation by a black-body material means you can double the output from a heat source, and with a material at emissivity 0.5 you can quadruple it.”
And he responded:
“Yes correct.”
Then, realizing that temperature and radiative output are related by the SB Law, he continued:
“In terms of temperature, for a theoretical blackbody insulator the temperature increase is 19% while for an emissivity 0.5 the increase is 41%”.
Again, DREMT fails to show bobdroege or MikeR used the words “insulation can increase the output from a heat source.”
It remains DREMT invented the words: “insulation can increase the output from a heat source.”
Try again DREMT & don’t mix up temperature and output.
You’re ridiculous.
Ball4 says:
Yes, I thought he got it because he said Q=0 between his plates.
I should have known better because of his many confused conclusions, for example that it meant stable temperatures despite heat loss on the outside of the green plate(s).
Poor Svante, still doesn’t understand what heat is.
Good example of DREMT dishonest debate tactics on display here.
In this instance twisting people words to make them appear to say ‘heat output’ when clearly they said ‘temperature’.
All to sow confusion while evading the key points that prove him wrong.
He is simply here to troll.
“There’s the unbelievable depths that the others will sink to…
…and then…way, way down…there’s Svante”
Although, of course, there are some that are prepared to go even lower.
I’ve been watching this CDAS sea surface temp. graph for about 3 years now. It hasn’t changed from its fluctuations around the +0.3 C anomaly.

The 3-year trend in ocean temperatures is +0.04C. Please explain your implied ability to see that sort of increase over noise of about 0.3C.

Scott R is no more than a specialist in eye-balling.

I’m a bit tired of trying to publish long comments which disappear without any hint on what might be wrong in them; thus here again, I post the complete comment via Google Drive:

Thanks Bindidon for the reply. Here is an exercise for people like Scott R who think they are good at eyeballing. Feel free to try yourself.
Following is a polynomial graph whose equation I won’t yet specify, to which has been added a sinusoidal function to simulate noise:
https://tinyurl.com/Guess-the-increase-in-trend
The question: By what percentage has the linear trend increased from start to end?
Thanks in turn for the convenient reply.
Your proposal for me to find out how much the trend increased unluckily is kinda blind-alley because I’m incredibly bad in… eye-balling!
I’ll wait for Scott R to offer his thoughts. However he has already posted elsewhere while deliberately overlooking this post, so I suspect he knows he will be caught out.
Bob,
Fun game, but without the units it will be impossible to estimate what the trend is.
I can tell you that this data is not linear, as I simply cut and pasted it, and drew some lines. Clearly in this case, you have data that is not linear, and for at least this portion of the dataset has at least 1 positive coefficient in front of one or more of your X^2… X^3 terms ect. Other than that, I won’t be able to do much else. I would not even be able to create data points one at a time without units.
“The question: By what percentage has the linear trend increased from start to end?”
It’s a trick question… it’s not a linear trend. Even if I were to eyeball an estimated gain over the data run and assign a %, since it is a polynomial, that information would provide nothing useful about predicting future data movements.
Looks like you haven’t even learned fundamental calculus concepts yet. I’m talking to a mathematical infant.
You want numbers – here is another graph with numbers on the vertical scale only:
https://tinyurl.com/What-is-the-trend-2
As I asked for the PERCENTAGE CHANGE in the trend, and not the trend itself, I hope you understand that I don’t need to give you the horizontal scale.
I’ve added an extra sinusoidal term to make it look a bit more like actual noisy data.
What is the percentage increase in the trend this time? A tip – it is more than it was last time.
Midas it is you that has underestimated me. Like I said, what value is there to eyeballing that chart and figuring out the percent? Just so that you can haha me when Bob reveals the equation? With a polynomial equation with who knows how many terms, the percent at the end of the dataset will have 0 predictive power to what comes next. I actually have an engineering degree by the way. I made it through diff eq. and obviously calc. I admit that Im very rusty as it has been 20 years since I used it, but that level of math isnt necessary to understand what I said.

There is no value to merely eyeballing a graph. Good to see you understand that now.
Still having trouble posting…
Midas, Bindidon
As Midas proved with his cherry picked example… NOAA did not identify the datum shift, so your list of trends is useless because it has a qualifier of “have not had their data flagged” and we know that datum shifts are in the data without being identified. You have to go to each data set and see what is happening one by one.
I will give you another chance Midas. Pick one dataset in which you say has an accelerating in sea level. I will look at it just as I did your other example. I don’t have time to go thru all of them right now.
Much appreciate.
I have given 74 gauges with have been active for at least a century, of which 58 show acceleration, with an average acceleration of more than 1 mm/yr/century. Why are you pretending not to have seen that?
Analyse them ALL, as I have taken the time to do.

I’m no American, and therefore don’t feel any need to refute data officially acknowledged by PSMSL.
THAT – and nothing else – is the one and only real source for ALL tide gauge processing.
What you think does not interest me at all.
Btw, it is one more time amazing to see that people like you, who consider all temperature providers as corrupt (UAH excepted of course because it fits to your ridiculous cold-is-right narrative), suddenly consider correct what the ‘corrupt’ NOAA considers good or not!
You are – and keep – incompetent.
Bindidon,
In perfect predictable fashion, you have no resorted to insulting me. It is the exact same method untrained, unscientific leftists try to use every day on me. Because I don’t agree with organizations A, B, C, and these select scientists D, E, F, that by default makes me incompetent.
You do not have to look very deep to see the issues with the selective identified datum shifts in the noaa tide data. The example Midas gave I looked at, I spoke the truth, and nobody here has give me any reason why what I said isn’t correct.
Midas alias Bob… alias Des?
Some weeks ago I extracted, out of all PMSL gauges having produced valuable anomalies for the reference period 1993-2013, those having provided data for at least 100 years (though this is by no means a qualifier for me).
Here is the extract out of PMSL’s filelist:
https://drive.google.com/file/d/1GhuqKGBiaBfNM3oC3Nx-1yaxISbcwMW9/view
*
The amazing point is the comparison of the plot for the period 1910-2018, of
– all about 670 baselineable stations (thus at least 21 years old)
with
– these 81 stations with at least 100 years activity:
https://drive.google.com/file/d/1UsJgaymQYMGiR1Vxc6cghgzBI5baeor0/view
The difference is incredibly small, especially when considering the trends for 1910-2018
– all: 1.61 mm/yr
– 100+y: 1.57 mm/yr
and for 1993-2018:
– all: 3.07 mm/yr
– 100+y: 2.88 mm/yr
That reminds me a comment made years ago at WUWT by Steven Mosher, stating that wrt temperature measurements, the Globe is widely oversampled.
Nick Stokes produced a valuable global land-only time series out of… no more than 60 stations.
Nevertheless the question remains: why does a sea level plot with only 3 (!) gauge stations in the South show so much similarity with a plot based on 125 of these Southern gauge stations?
Midas,
Respectfully, I do not have time to check all of them right now. Pick the one with the sharpest trend, let me know what city that is, and I’ll pull the NOAA data and look at it. Honestly, showing me 80 cities, all of them with different sea level acceleration values (note I didn’t check your work) if anything proves just how important local geological changes are, and how insignificant human caused changes to sea level actually are. Pretty much the opposite of what you are saying.
Folks I apologize for the bottom posts. For some reason I have more luck down here. In regards to Midas’s test…
Midas it is you that has underestimated me. Like I said, what value is there to eyeballing that chart and figuring out the %? Just so that you can haha me when you reveal the equation? With a quadratic equation, the % will have 0 predictive power to what comes next.

OK, so for anybody that answered c), to the above, whether internally or if they actually commented, I also asked a follow-up question.
In the 3-plate scenario, what is the temperature of the blue plate when the green plates have 50% reflectivity?
The answer, according to the GPE “logic”, is 345 K, with the green plates at a temperature of 290 K. That the green plates have emissivity = 0.5 means they are still emitting 200 W/m^2 at 290 K, just like they were emitting 200 W/m^2 at 244 K, when emissivity = 1.0.
At 345 K the blue plate is emitting 800 W/m^2. 800 W goes to the right, and 800 to the left. 1600 W is the total output from the blue plate (assuming it is 1m^2 in height for ease, with 2 sides, obviously).
Inputs:
400 W from the electrical source to the blue plate.
800 W reflected from the green plates (400 W each).
400 W emitted by the green plates (200 W from each plate is returned to the blue plate, the 200 W from the other side of each green plate is going out to space, of course).
Total Inputs = 1600 W. Everything is in balance, according to GPE “logic”.
Everyone agree?
Yes DReMT it is all correct for a blackbody ( emissivity of 1) with the exception that the temperature of the blue plate is then 289.8 K. You have just put in words the depiction I posted a week or so ago see-
https://i.postimg.cc/J454kTT1/Three-Plates.png
However for an emissivity of 0.5 for the green plates the temperature of the blue plate is 320.73 K see –
https://i.postimg.cc/cLv8Tpyw/3-plates-with-emissivity-Excel.jpg .
It is a screen dump of an Excel spreadsheet that outlines calculations for the 3 plates for varying emissivities.
The calculations demonstrate that
1. When the green plates are blackbodies (emissivity =1) the temperature of the blue plate is 289.81 C as reported before.
2. The temperature asymptotes towards infinity as the emmisivity approaches zero.
3. For green plates with an emissivity of zero ( i.e mirrors) the energy balance equation for the system is no longer relevant as it is a lossless system and there is no energy leaving the system via the green plates. In this case the equations now produce indeterminate answers for both E1 and E2. Singularities like this are handled by looking at how the function behaves when the emissivity approaches zero (See 2. above)
I may need to remind everyone this is a simulation of a thought experiment. The plates are supposed to be infinitely long (view factors =1) and infinitely narrow. The 400 W source can also generate this power indefinitely.
Obviously in practice we are dealing w with finite objects and finite time durations so this infinite energy system will never arise.
The claim that the mirrors create energy is absolute b.s.. They just capture it. The infinite energy of the system is actually due to to the 400W input running for infinite time ( for the case when the blue plate has a non zero heat capacity).
On that note if we suddenly stop the 400W input , the energy of the system (and consequently the temperature of the blue plate) would not drop. This because this lossless system, can be described as a thermal capacitor or the perfect insulator. This why metallic foil insulation (mirrors are a bit inflexible) is commonly employed despite the cost in many area, from thermal blankets to the surfaces of spacecraft.
The Excel spreadsheet itself can be downloaded from Google drive and all are welcome to play with it. Here is the link

Good job here, DREMT. Your answer agrees with standard thermodynamics as taught in physics classes and as employed by practicing engineers around the world.
At 345K, the blue plate has a total output of 1600 W and a total input of 1600 W. The net power is 0 W, so its temperature will stay steady @ 345 K.
Or stated another way, the blue plate has a net input (electrical) of 400 W and a net loss (radiative) of 400 W.
It will be fascinating to see where you think you are going with this.

I am in 100% in agreement with Tim Folkerts and others. Tim’s temperatures for the green plate are correct assuming both sides of the green plate have the same emissivity. This is in accordance with my spreadsheet.
The other case that assumes the opposite side has an emissivity of 1 is also in accordance with my calculations.

Sorry to do this again. My previous version was correct with respect to the the temperature of the green plates. The temperature is 244 K for all emissivities other than zero, see –
http://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-414919
This is the previous version which is correct.
https://i.postimg.cc/y8747TNp/3-plates-with-emissivity-Excel-corrected.jpg
Wrong.
Au contraire. For the case where the emissivities are the same on both sides of the green plates-
https://i.postimg.cc/9MZznnfW/3-plates-emiisvity-same-on-both-sdies.png
and for the case where the external side of the green plates has an emissivity of 1 –
https://i.postimg.cc/ZnLnTv32/3-plates-emissivity-1-on-outside-green-plate.png .
We had only been discussing the case in which the emissivities are the same on both sides of the green plate, for which you previously gave the wrong answer on two occasions.
The other case is a desperate distraction you came up with, both to deflect from the absurdity of the case we are actually discussing, and to try to cover your tracks over the errors you already made.
As was discussed and agreed to earlier there is no requirement for the emmissivity to be the same on all surfaces of an object (with the exception of a black body).
You didn’t specify in the question you posed that the emmissivity had to be the same on both sides. I have presented above , the results for both cases, which are now correct (after seeing Tim’s post). You are presenting nothing substantive here so what else do you want me to provide?
Perhaps a lobotomy so we can continue our exchanges on more equal terms? There are limits.
I’m sorry that you made mistakes, that there is a permanent record of that, and that this has hurt your massive ego.
For the situation for emissivity being the same on both sides of the green plate, I was right in my first comment. Sorry Mike, you can’t condescend any more when you got it wrong and I didn’t, and I had to correct you.
The other case is a desperate distraction you came up with, both to deflect from the absurdity of the case we are actually discussing, and to try to cover your tracks over the errors you already made.
Can’t say it made a massive dent to my ego and how’s your fragile ego standing up?
On that note, the ability to admit mistakes and move on is invaluable. You should try it.
I think it hurt you more than a little.
Just a touch and fully recovered. See it’s simple. Why not give it a go. It’s not like you have got a lot of credibility to lose.
Give what a go?
Admitting to mistakes and moving on, of course.
Not just errors of judgement but addressing your delusions such as your interpretation of thermal physics would be a good start. In fact getting help from a professional might be advisable.
I’m still confused. Define “but”.
“and” might be better than “but”.
Hope that clears up the confusion.
Define “that”.
Look up ibid.
Define “i”.
I know who I am. Are u going through an identity crisis?
Define “who”.
I will only answers about “who” if you can provide documentary evidence thay you are capable of climbing stairs. Do you understand?
Define “will”.
Obviously not.
Too lazy?
Just terrified.
How come? Just use a dictionary and tell me the definition. Nothing to be scared of.
It was the “who” reference that terrified me. Still don’t get it?
“Who” is in the dictionary too. Why are you afraid of words?
I am returning to the Tardis. Bye.
Define “to”.
Must remember to program the Tardis’s answering machine with “I am away at the moment seeking intelligent forms of life and no longer available to answer questions from non sentient beings”.
He obviously hasn’t worked out the definition of “bye”.
Please leave a message after the beep.
Define “message”.
The Dr is not available at the moment as he is still within the event horizon. Your call is being diverted and will be answered by the next available operator.

“Dr”, he says. But “Dr” Who</b!?
Yes DReMT your calculations are correct for a blackbody ( emissivity of 1) with the exception that the temperature of the blue plate is then 289.8 K. You have just put in words the depiction I posted a week or so ago see-
https://i.postimg.cc/J454kTT1/Three-Plates.png
However for an emissivity of 0.5 for the green plates the temperature of the blue plate is 320.73 K see –
https://i.postimg.cc/cLv8Tpyw/3-plates-with-emissivity-Excel.jpg .
OK, then…so it’s MikeR vs. Tim.
It will be fascinating to see where they are going with this disagreement.
Actually, it’s (Mike & Tim with one minor point to iron out) vs (DREMT with multiple misunderstandings).
Hmmm…no, I believe it’s MikeR vs. Tim plus “standard thermodynamics as taught in physics classes and as employed by practicing engineers around the world”.
DREMT pondered:
“Actually, MikeR, one more thing, on that subjectwhat do you think the temperature of the blue plate would be, in the 3-plate setup, if the green plates were both perfect reflectors?
a) 244 K (GPE debunked)
b) 290 K (a BB plate works the same as a perfect reflector!? GPE debunked)
c) Infinity K (we could have been using mirrors all this time to tap unlimited free energy!? GPE debunked)”
Here is but one example of your misunderstanding, DREMT. As Mike already explained, (c) is the correct answer, but this would be a perfect *sink* of energy, not a perfect *source* of energy. Oh, you could “tap” this and get a steady 400 W out (or briefly get a larger pulse), but that is not “unlimited”. Nor is that “free” since you had to pay to put the electrical energy in to begin with.
If you are putting 400 W in, and tapping 400 W out, that leaves you no power to warm the blue plate above 0K.
Oh well.
If you are putting 400 W in, and tapping 400 W out, that leaves you no power to warm your 400W incandescent light bulb above 0K.
Oh well.
A light bulb wouldn’t work too well if the inside of the bulb was a perfect reflector. Never mind.
There no perfect reflectors DREMT. Think again.
I agree. But since you didn’t have a point (it’s not the material of the bulb itself that generates the light, it’s the filament), there was nothing really worth responding to. So I thought I’d just laugh at you instead.
My point is many blog readers do understand DREMT often laughs while demonstrating a lack of knowledge in text book thermodynamics such as at 3:49pm, 1:52pm. DREMT has lost debates so often that it really is laughable. Oh well. Carry on clowning DREMT and PST.
NB: Cool, sometimes at least, my comments are posting now.
Words said in response to you.
(P.S: I’m glad you agree that if you extract the power required to warm the filament, then there’s no power left over to warm the filament).
‘theres no power left over to warm the filament)’
POWER is RATE of energy flow. Do you need a higher RATE of energy flow to add more energy to something?
No.
Just briefly reduce the RATE of energy outflow via insulation.
Will you ever learn the difference between POWER and ENERGY?? It seem not.
Let’s just adjust Ball4’s comment:
“If you are putting 400 W [joules/sec] in, and tapping 400 W [joules/sec] out, that leaves you no power [joules/sec] to warm your 400W incandescent light bulb above 0K.
Oh well.”
That’s better.
Dr Roys Emergency Moderation Team says:
“If you are putting 400 W [joules/sec] in, and tapping 400 W [joules/sec] out, that leaves you no power [joules/sec] to warm your 400W incandescent light bulb above 0K.”
Good luck tapping 400 W from a 0 K object.
Supplied 400 W. Any temperature increase above 0 K produces an output that is continually extracted, such that 400 W is tapped out.
Nope DREMT/Joe, the 400W light incandescent light bulb will be far above 0K with 400W in and 400W tapped out. You don’t know what you are talking about. An LED light bulb will also be far above 0K but far different temperature.
You “people” now try to argue I’m Postma, a physicist with a masters in Astrophysics; whilst simultaneously arguing I don’t know the difference between power and energy. Or temperature and power.
Make up your minds.
Apparently, a self-proclaimed Master in Astrophysics avoided learning how common heat shields & Earth’s GHE work not necessarily the difference between power and energy.
Pithy response.
Dr Roys Emergency Moderation Team says:
“Any temperature increase above 0 K produces an output that is continually extracted, such that 400 W is tapped out.”
Not any temperature. Only one specific temperature that depends on its cold surroundings.
In other words, the surrounding environment can change the temperature of an object. Up or down.
Well, Svante…if you have “surroundings”, like air in a room, rather than an infinite perfect vacuum (which would be the absence of “surroundings”) and that “surrounding” air has a temperature greater than the object itself could possibly have warmed it to, then you must have an additional heat source somewhere.
And when you have more than one heat source in the situation, you are no longer discussing anything that relates to either the 2-plate or 3-plate scenario, in which the only heat source is the sun, or the blue plate, respectively.
Nice diversionary tactics.
I said *cold* surroundings, try again.
It can be empty space or air in a room.
Conduction, convection or radiation.
I tried the first time and got it right, so why would I try again?
Dr Roys Emergency Moderation Team says:
So tell me how you tap 400W from a 1 K object.
Yes, it is possible!
I don’t mind if you don’t understand, or are pretending not to. I’m fine with that.
Easy, give it an environment that has enough cooling power.
Net energy surplus means rising temperature.
Reduce the cooling power to create that surplus.
“Reducing the cooling power” = “warming the environment” = “adding an additional heat source”.
It’s not an additional heat source if it’s the cold surroundings?
Heat does not move from cold to hot spontaneously.
It’s called the 2nd law of thermodynamics.
How do you make the cold surroundings less cold, without adding an additional heat source?
Examples:
Reduce CPU fan speed.
Put a jumper on.
Put a lid on your pot.
Change single to double glazing (with a gap between).
Keep a gap between your green and blue plates.
How do you warm a vacuum, Svante?
You screen it off.
What you see is what you get.
The correct answer is, “you can’t”.
Net energy loss rate depends on (T^4) temperature difference.
Let a screen catch energy that would otherwise be lost to space.
The energy will warm the screen and reduce net energy loss rate.
Your heated object will get an energy surplus and warm up.
How can you not see that means you’re getting something from nothing!?
Because universe entropy increases in Svante’s 6:42pm process which DREMT/Joe does not comprehend, thus there is NOT something for nothing.
Dr Roys Emergency Moderation Team says:
“that means youre getting something from nothing!?”
No, the screen catches energy that would otherwise be lost to space.
“No, the screen catches energy that would otherwise be lost to space.”
That’s not the “something from nothing” referred to.
What do you mean?
Some semantic point?
The answers to your questions are “what I said” and “no”, respectively.
Can anyone else understand what he means?
Poor Svante. Always so “confused”.
Yes, many others know what DREMT/Joe means, Savante 7:16am.
DREMT/Joe means all heat sources are perfect reflectors of energy but there are NO such real materials experimentally found in nature including the natural Earth L&O surface and air.
DREMT/Joe cannot comprehend even glowing filaments of incandescent light bulbs absorb and emit energy. DREMT/Joe’s incorrect view is a result of his misapplication of 2LOT. DREMT/Joe cannot understand that the 2LOT must be satisfied by increasing its entropy evidenced by a temperature increase during the process of absorbing the energy from your screen (~dq/T).
Confused DREMT/Joe incorrectly claims the filament stays at the same temperature in the real process (thus ignoring dq/T) which does not increase its entropy and is thus ruled out by 2LOT.
All this thoroughly confuses DREMT/Joe (especialy as applied to the plate problems) who cannot understand and will never demonstrate an understanding of how Earth’s atm. radiation budget works as found experimentally.
Ball4 piles on the straw.
No, I was referring to Svante’s “confusion”. Particularly his inability to distinguish between “objects” and “surroundings”, and his attempts to get around the fact that you can’t warm a vacuum.
I was writing for Svante, not DREMT/Joe who will never understand a vacuum can contain energy (and thus mass) & any energy source can absorb some of it.
No longer content just to argue that the Earth warms the sun…they now want you to believe the vacuum of space warms the sun!
Perfect in their absolute stupidity.
Svante, DREMT/Joe now writes the vacuum of space can warm the sun, no that’s just another of DREMT/Joe’s many misunderstandings.
The vacuum of space cannot warm the sun.
The Earth cannot warm the sun.
Svante, this is where DREMT/Joe doesn’t understand 2LOT: “The Earth cannot warm the sun.”
DREMT/Joe doesn’t understand, and never will understand, his statement is wrong, precluded by 2LOT as the system’s main energy source’s entropy is NOT increased by the real process he describes.
Thanks for asking to show you what DREMT/Joe incorrectly understands.
What did you say in this comment, Ball4?
https://www.drroyspencer.com/2019/03/uah-global-temperature-update-for-february-2019-0-36-deg-c/#comment-345722
Svante, now DREMT/Joe 1:05pm writes something I don’t understand, do you? Likely just another of DREMT/Joe’s misunderstandings in this field.
Ball4, I’m not so sure.
I think he knows that he is wrong, that’s when he goes into his vague/evasive loop.
At the same time he shows some fundamental misunderstandings, for example that the plate example produces something from nothing, when it actually comes out of the 400 fresh Joules that arrive each second.
Answer the question, Ball4.
Svante 3:34pm, agree. DREMT/Joe 3:43pm now writes a demand to answer his obviously unclear question. He apparently doesn’t understand that anyone can click on a link to clearly find what was written in any such linked comment as his 1:05pm question’s answer is in plain sight. DREMT/Joe doesn’t understand again. This is substantial evidence understanding the more complex 2LOT is beyond DREMT/Joe’s ability in this field.
This is what you wrote:
“JD’s separated version would have the middle (blue) plate increasing in temperature with no change in incoming or outgoing energy, which IS a clear violation of 1LOT law of physics, typical for JD as an entertainment specialist:
244K…290K…244K
When the givens are the same as the GPE, then upon separation the middle plate increases in temperature closer to 262K and the other two green plates decrease in temperature i.e. they don’t stay at 244K as JD shows, they decrease closer to 220K to conserve system energy. JD is just as confused as ever, nothing new.
JD should learn some physics or continue to be the blog entertainer.”
Let me ask you another question, instead, then:
What is the correct answer to the 3-plate problem? The temperatures of the 3 plates, please.
Svante, DREMT/Joe’s 1:05pm, 4:13pm requested answers are in plain sight as I wrote. More substantial evidence DREMT/Joe 4:13pm can’t be relied on to understand the 2LOT.
Surely the answers DREMT/Joe needs could be confirmed with details provided in any test rig actually built by DREMT/Joe of the 3 plates configuration, replicable data taken, and then published by DREMT/Joe confirming the answers he seeks which are in plain sight. In the process improving DREMT/Joes understanding of the complexities of the 2LOT.
Svante, I realize E. Swanson already did so, but DREMT/Joe has never published his replication w/experimental data to confirm the answers within experimental statistical error ranges. Pretty sure with that experience behind him, DREMT/Joe could move on, build another experiment to confirm Eli’s setup answers.
What is the correct answer to the 3-plate problem? You obviously don’t think it’s 244 K…290 K…244 K. So what are the temperatures of the 3 plates, as you see it?
Svante, I again observe DREMT/Joe 4:47pm still doesn’t realize the answers he seeks are in plain sight.
Svante, also to get more precise answers, DREMT/Joe will need to build a test rig and decide things like: is the blue plate electrical resistance provided by 1) an incandescent light bulb, 2) an LED light build, 3) an electric motor for at least 3 examples.
So your answers are (approximately)…220 K…262 K…220 K. OK then. Why the difference to everybody else’s answer?
Svante, DREMT/Joe 6:21pm asks a question about a commenter “everybody else”, perhaps you can point out exactly what answers the commenter “everybody else” supplied.
The reasons why JD’s cartoon answers were wrong are already in plain sight; same reason as DREMT/Joe’s misunderstandings, JD also didn’t invoke the complexities of the 2LOT correctly thus invoked non-existent perfect reflector plates.
I do apologize for the imprecision over the use of the term “everybody else “.
To clarify, JD and myself go with: 244 K…244 K…244 K.
This is the list of people who go with: 244 K…290 K…244 K.
E Swanson
Svante
bobdroege
MikeR
Kristian
Chic Bowdrie
Tim Folkerts
Snape
Just off the top of my head, I could well have forgotten some people. Anyway…
…by going with: 220 K…262 K…220 K, you disagree with all the people above. I was just wondering why that was?
Svante, it appears DREMT/Joe also suffers imprecision in reading in addition to his misunderstanding the complexities of the 2LOT.
At 7:28pm, DREMT/Joe wonders & lists a number of commenters that have discussed the 400W electrically warmed center plate and erroneously compares their answers (with his words not theirs) to my linked comment answers clearly discussing the original GPE “When the givens are the same as the GPE” which DREMT/Joe started with on that particular subthread 3/16/2019 8:13am: “Anybody prepared to accept that the Green Plate Effect is debunked?”
JD tried and failed to debunk the GPE with wrong basic physics as I repeatedly pointed out. In order to criticize the GPE, anyone doing so clearly needs a misunderstanding of the complexities of the 2LOT which both JD and DREMT/Joe mean to demonstrate along with certain reading issues.
Thanks again for asking 7:16am to show you what DREMT/Joe means.
Ball4’s own words from the linked comment were:
“When the givens are the same as the GPE, then upon separation the middle plate increases in temperature closer to 262K and the other two green plates decrease in temperature i.e. they don’t stay at 244K as JD shows, they decrease closer to 220K”
So by Ball4’s own words from the linked comment Ball4 confirms that Ball4 was not talking about the original Green Plate Effect, as Ball4 references “two green plates” in Ball4’s own words, whereas in the original GPE there was only 1 green plate.
So Ball4 was not “clearly discussing the original GPE” in his linked comment, as Ball4’s own words in Ball4’s 10:00pm comment erroneously stated.
Svante, now I see that DREMT/Joe also means he has issues with counting plates & understanding simple givens in two different thought experiments.
When the givens are the same as the GPE, then there are two plates one blue & the other green, after all the G in GPE stands for “green”. Then upon JD’s introduction of the separation of the blue plate into another green plate, there are three plates and the 2 greens must decrease below the temperature of the middle blue plate with greens closer to 220K at steady state equilibrium with givens in the illumination of the original GPE.
This means, Svante, many, including a self-professed master of astrophysics, reading my original comment, could have then found both JD and DREMT/Joe should have realized their solution to the electrically powered middle blue plate in JD’s original thought experiment MUST be wrong at steady state. And many did point that obvious mistake out to DREMT/Joe as DREMT/Joe writes.
DREMT/Joe’s solution of JD’s givens is still wrong to this day Svante, as you et. al. point out, after all this time, DREMT/Joe has not benefited from the insight of all the folks mentioned by DREMT/Joe proving he’s at least aware of their comments attempting to correct his truly obvious erroneous analysis of JD’s givens.
Svante, it is also obvious to many that for DREMT/Joe to mean to prove his solution to JD’s thought experiment given is correct physics, then building a reasonable, proper test rig is necessary as did E. Swanson. DREMT/Joe assertions are not getting anywhere with the critical, informed crowd around here as often as he has tried.
“When the givens are the same as the GPE, then there are two plates one blue & the other green, after all the G in GPE stands for “green”. Then upon JD’s introduction of the separation of the blue plate into another green plate, there are three plates and the 2 greens must decrease below the temperature of the middle blue plate with greens closer to 220K at steady state equilibrium with givens in the illumination of the original GPE.“
The illumination in the original GPE is a sun to the left of the blue plate and green plate. So what you are describing is, in sequence from left to right: the sun, then a green plate, then the blue plate, then another green plate. And you say the temperatures are 220 K for the green plates and 262 K for the blue. Please explain.
Svante, I see what you mean by “I think (DREMT/Joe) knows that he is wrong, that’s when he goes into his vague/evasive loop” as he does at 9:21am. I have not changed since March “When the givens are the same as the GPE” and now he presents yet another arrangement where the sun no longer illuminates the blue plate so the givens are NOT the same as the GPE when JD’s separation is added.
You’re ridiculous. The personification of dishonesty.
Ball4 says:
DREMT reminds me of the tobacco and fossil fuel industry messaging:
– “Doubt is our product”
https://en.wikipedia.org/wiki/Doubt_Is_Their_Product
DREMT does not want to clarify, he wants to create confusion.
Last word.
Since that reply went through, lets try something bigger …
************************************************
MikeR,
I cant download you spreadsheet, but I am pretty sure it has an error. I suspect you don’t deal with the reflected IR from the green plate properly.
If both sides of the green plate have emissivity = 0.5 (and the plate is thin so both sides are the same temperature), then the outer green surfaces have to be 290 K to emit 200 W/m^2 to space. We agree so far. Therefore the inner green surfaces also emit 200 W/m^2 toward the blue surfaces.
If the blue plate has emissivity = 1, then it must indeed emit 800 W/m^2 from both sides, not 600 as your spreadsheet calculates!
In between the blue plate (one side) and a green plate:
* 800 gets emitted by Blue
** 400 of that gets absorb.ed by Green
** 400 gets reflected back to Blue and gets ab.sorbed
*** All 400 of the reflected IR gets ab.sorbed by Blue
* 200 gets emitted by Green
** all 200 gets ab.sorbed by Blue
NET IR FOR BLUE (one side): -800 loss (emitted) +400 gain (reflected) +200 gain (emitted by Green) = -200 W/m^2 of thermal IR leaving.
NET IR FOR GREEN (inner side) +400 gain (ab.sorbed from Blue) 200 loss (emitted by green to Blue) = + 200 W/m^2 of thermal IR ab.sorbed from Blue.
Adding up all the surfaces, sources, and sinks
* Blue gets +400 electrical and loses 2200 net thermal IR = balanced
* Green receives 200 net IR from Blue and emits 200 net IR to space = balanced.
I came up with that Blue plate temperature of ~345 K.
I hope this finally gets though .I have been trying to post this for almost 2 days after I saw Tim Folkert’s post.
Apologies to all .
Yes I was wrong. The emissivity = 1- ( E2 – E3) / E1 not E3/E2.

Lesson learnt.
Due to the difficulties working with the dysfunctional comments section my humble piet was baked blind, but it was still rather tasty for a humble pie.
For those who are incapable of admitting to making a mistake, you should try it.
The green plates don’t stay at the same temperature, Mike. At emissivity 1, according to the Green Plate Effect “logic”, they are 244 K. At emissivity 0.5 they are at 290 K. Still emitting 200 W/m^2. They keep increasing in temperature as the emissivity decreases, always emitting 200 W/m^2. Try again.
Yes correct.

Wrong.
I am in 100% in agreement with Tim Folkerts and others. Tim’s temperatures for the green plate are correct assuming both sides of the green plate have the same emissivity. This is in accordance with my spreadsheet.
The other case that assumes the opposite side has an emissivity of 1 is also in accordance with my calculations.
I have updated my screen dumps of the calculations to make this clearer.

Does anyone know why symbols such as the negative sign and apostrophes are sometimes mangled by WordPress? I thought ASCII was ASCII, even in these days of Unicode.
Maybe it’s the copy and paste from Word which causes the issue?
There seems to be a mistake in the charset definition.
Should probably be:
It fails even if you copy from the same page, you need to rewrite all quotes and non-ascii characters.

Where did you get 290 K from? Not according to my calculations linked to above
They are at 244K for all values of the emmissivity (see Column F of the spreadsheet). I think you are a bit confused.

Your link is to your own work! Where did you get the 290 K from?
Mike, as you observe around here, DREMT is often a bit confused about text book thermodynamics. DREMT hasn’t won a debate on this blog evah! DREMT’s confusion better fits in commenting at the climate sophistry blog.
A green plate at 290 K with emissivity 0.5 is emitting 200 W/m^2. 200 W from each green plate is returned to the blue plate, 200 W from each green plate goes to space. 2 green plates = 400 W returned to the blue plate. That is what the GPE logic requires. Check my comment.
A green plate at 244 K with emissivity 0.5 is emitting 100 W/m^2. 100 W from each green plate is returned to the blue plate, 100 W from each green plate goes to space. 2 green plates = 200 W returned to the blue plate. That is 200 W less than the GPE logic requires. Check my comment.
Yes you are right. The temperature of the green plate varies with emissivity. I shall post new links accordingly. More yummy humble pie for me.
The answer to the question you posed is still most definitely (c) . What’s your opinion on the matter?
I spoke to soon! The previous version was correct.I should have realized that whatever DREMT has to say on any matter involving physics is extremely unlikely to be correct see –

Thanks Tim for confirming my calculations.
I believe DReMT thinks this
https://i.postimg.cc/mgt4VZBQ/three-plates-DREMT.jpg
is the correct depiction of the 3 plate problem for all emissivities for the green plate, including zero emissivity!
MikeR seems to be having some sort of meltdown.

Glad everyone is finally up to speed on the calculations they are trying to pretend represent “standard thermodynamics as taught in physics classes and as employed by practicing engineers around the world”, yet which seemed to be a source of much confusion for them…
…so I’m still waiting for a response from Tim to this point:
https://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-414738
…and on the GPE “logic” for the emissivity problem:
1) How can the green plates be at an infinitely high temperature when their emissivity is at zero? Nothing is being absorb.ed, and everything is being reflected, at zero; and yet as their emissivity approaches zero the temperature of their green plates is increasing higher and higher and higher and higher…
2) It is always required, according to the GPE “logic”, at all values of emissivity, that the green plates be absorbing and emitting 200 W/m^2. So how is this possible at emissivity = 0?
Those are actually some interesting questions DREMT. You actually hint at the answer within your question itself when you say both “when their emissivity is at zero” and “as their emissivity approaches zero”. These are two very different beasts!
There are many cases in mathematics where f(a) is not equal to f(x) in the limit as x approaches a. For example, as x goes to zero, sin(x)/x goes to 1, but sin(x)/x is undefined.
Similarly, the calculations for the blue/green plates give undefined answers for emissivity exactly equal to 0. We can take limits (as you hint at) and see what the answer would be as you get for the blue and green plates arbitrarily close to zero.

If you try to actually set emissivity exactly to zero, then the nature of the solution changes. Until now, the green plate could radiate to space, and the green plate would reach some definite, finite temperature. But with emissivity = 0, the problem fundamentally changes, because there is no temperature where the green plate radiates 200 W/m^2 to space. The “steady-state solution” does not exist! the plates do not EVER reach a specific stable temperature (or more precisely, the blue plate never stops getting hotter and the green plate never changes at all).
Tim tries to talk his way out of the problem.
Re DReMTs questions. Tim has provided a sensible answer but DREMT does not appear to have the requisite maths background so here are answers which may help DREMT’s understanding.
Answer to 1) The green plates are at zero K for an emissivity of zero for the surface facing the source. All the radiation is reflected and none is absorbed.
Consequently the equations for energy balance for the system are not applicable when you have no energy leaving the system. This should be obvious.
Answer to 2) Again for an emissivity of zero the green plate is not generating 200 W because it as at 0K. All the energy being generated by the source is being reflected back to the source by the reflective (emissivity =0) surface of the green plate.
“Re DReMTs questions. Tim has provided a sensible answer”
He has no answer. Tim merely notes the difference between “emissivity is zero” and “the limit as emissivity goes to zero”.
There is no answer which doesn’t just skirt around the problem.
Tim has made a distinction which someone with a background in mathematics would understand. As you are confused you could try educating yourself by reading this
https://en.m.wikipedia.org/wiki/Limit_(mathematics)
and
https://en.m.wikipedia.org/wiki/Asymptotic_analysis .
With regards to limits your arrogant disregard of physics and mathematics is testing mine.
I understood, thanks.
You worship Eli’s math, and ignore physics and reality.
I’m sorry for your argument loss, but happy with the win.
I am pleased for you that you think you have won. Good for you. Personally I would prefer to leave that judgement to others.
I was just letting you know the facts.
I have never observed you to have any concerns regarding the facts. What happened?
But again, let’s leave it for others to decide.
Huh? What do you mean by “have”?
Consult your nearest dictionary.
What do you mean by “dictionary”?
It’s sine qua non for basic literacy. Use it to look up “naughty boy” and then “ibid”.
What do you mean by “it”?
You need to be more specific.
Which “it” are you referring to? The “it” in iterative? Or the “it” as in “it is getting very boring”.
What do you mean by “specific”?
As in, if you can’t take the specific heat then get out of the kitchen.
Alternatively it could be a misheard request by a drunk who then sings, “I gotta get this moron out of my hair”.
What do you mean by “as”?
Just a slight typo it was meant be “ass”.
Any of the commonly understood meanings is appropriate.
What do you mean by “of”?
Of mice and men. What are you?
Happy.
That’s nice.
Yes.
Good. Bye.
It’s really easy to say goodbye. You just say it…but, unfortunately, you then have to stop responding. Otherwise you’re not really saying goodbye.
You say hello, I say goodbye.
You’re halfway there.
Yes just the second half.
Goodbye.
No, you’re messing up the second half. You can’t stop responding.
Over and out for me. You now have the airwaves to yourself. Try not to go wild and have a good break over Xmas.
I’ll be fine, since I’m a human being. I don’t know what you are.
My advice to try and not go wild. That worked well.
Over and out again.
Hush, child.
DREMT, you make a thought provoking point in 1)
The thought I have is that I should not have listened to you earlier regarding the effect of emissivity of the green plate. . It looks like I need to go back and link to my previous version.
This earlier version was correct. The temperature of the green plate is 244K for all emissivities other than zero. The emissivity of the surface of the green plate facing the blue plate source is less than 1 which means some, or most, of the energy returned is reflected energy ( including thermalised back radiation). From the other side of the green plate, the emissivity is 1 and 200 W is always being emitted from this surface which means the temperature is 244K.
The only exception is when the emissivity of the side facing the source is zero , see point 2) below. For very low emissivities of this side, the very large amount of energy being returned towards the source is due to reflection of a large amount of energy from the high temperature source, not simply from thermal radiation.
For point 2)
As the emissivity of the surface of the green plate facing the source is zero, this results in all the energy being reflected back towards the surface and therefore no energy is absorbed by the green plates. As no energy is absorbed by this plate it means the green plate is at 0 K and consequently no energy leaves from the face opposite the source.
As there is no way energy can leave the system via the green plates, then the continual input of 400 W into the blue plate will mean eventually, at steady state, an infinite temperature for the blue plate (for steady state conditions, this will take infinite time for a plate with non zero heat capacity).
I hope this explanation answers your queries regarding answer (c).
DREMT, will you now reply how answer (a) with all plates at 244 K, can possibly satisfy energy conservation for all 3 plates? To inspire you I am linking to this depiction which represents (a). If you are not happy with this depiction, let me know.
It would be wonderful if you even attempted to explain this, but knowing you, I am not holding my breath.
YIKES! Suddenly people are discussing various different scenarios for the emissivities of the two sides of the green plate without clearly distinguishing which they mean! Not surprisingly, these have various different answers. Also not surprisingly, this leads to confusion!
The emissivity of the inner surface could be:
A) ε = the limit as x goes to zero
B) ε = 0
The emissivity of the outer surface could be:
a) ε = the limit as x goes to zero
b) ε = 0
c) ε = 1
My starting point has always been “Aa”. This is the typical approach when “B” or “b” leads to undefined solutions.
Mike’s latest post seems to consider “Ac” and “Bc”.
DREMT doesn’t seem to distinguish between “A” & “B” or between “a” & “b”.
dang, all those “ε” should be “epsilon” = ε = emissivity. (and now this will probably come out wrong, too.)
TF wrote: “YIKES! Suddenly people are discussing various different scenarios for the emissivities of the two sides of the green plate without clearly distinguishing which they mean!”
Yeah, when did these guys suddenly decide that the emissivity of the outer side of the Green plate was 1.0 for all cases?
Lol. Obviously the emissivity of both sides of the green plate are the same. Talk about desperate.
DRsEMT, Yes, that was my assumption until I saw this from MikeR above:
You are the one who is desperate, as your deviant physics (still) doesn’t work.
MikeR is on your “side”, Swanson.
And no, both sides of the green plate have the same emissivity throughout. The other side of each green plate, facing space, is not fixed at 1. That side of each green plate is always emitting 200 W, because as the emissivity drops from 1 to 0, on both sides of the plate, the temperature of the green plate increases proportionately.
This is all according to your deviant physics.
(I mean, the green plates are always emitting the same amount towards the blue, regardless of their temperature, so why would the temperature of the blue plate change!?)
DREMT you are confused again. The radiation returned by the green plate varies as the emmissivity changes. The requirement that both sides of the green plate emits the same amount of radiation is only for a black body.
See the column labelled E2 in the spreadsheet
https://postimg.cc/474JKwtM
I said, “emitted”. Not “returned”
Keep thinking…
Oh you mean E3. That’s obviously always 200 W (except for the e=0 mirror case) as a consequence of the conservation of energy for the whole system.
I am surprised you even thought to ask, as this is the only of the 3 energy equations you managed to get right see –
https://i.postimg.cc/4N3qk7TH/3-plates-DREMT-nightmare.png
I mean E2 and E3.
E2 = emitted plus reflected.
The blue plate is heated by the emitted and reflected radiation, so what’s the problem?
Whoops! Posted in the wrong place:
https://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-417651
You are sick.
DREMT,
Despite your claims to the contrary , there is no requirement for an object to have the same emissivity.
Emissivity is a surface phenomenon, see –
https://en.m.wikipedia.org/wiki/Emissivity
DREMT you need to take a good look at yourself in a mirror. Other than seeing a dolt staring back at you, you may notice the reflectivity of both sides of the mirror will be different.
The only exception where all sides must have the same emissivities is a definitional one. A black body is defined as having all surfaces with emissivities of one.
I’m not saying there’s a “requirement”. I’m saying you are introducing an unnecessary complication in order to get out of a situation you have trouble explaining.
It’s always good to see DREMT squirm. He is now walking back his statement.
“Lol. Obviously the emissivity of both sides of the green plate are the same. Talk about desperate.”
That sounds awfully like like a requirement to me.
The only part of your statement that makes sense is the ” Lol” as you are, yet again, the butt of the joke (emphasis on butt).
Swanson said, “Yeah, when did these guys suddenly decide that the emissivity of the outer side of the Green plate was 1.0 for all cases?”
By “these guys” I assumed he was lumping us together. I was just making it clear that this wasn’t the scenario we had been discussing. The scenario you are artfully avoiding…the one Tim already agreed the temperatures for:
https://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-414817
So there is no way out now…
DReMT’s questions.
“1) How can the green plates be at an infinitely high temperature when their emissivity is at zero? Nothing is being absorb.ed, and everything is being reflected, at zero; and yet as their emissivity approaches zero the temperature of their green plates is increasing higher and higher and higher and higher
2) It is always required, according to the GPE logic, at all values of emissivity, that the green plates be absorbing and emitting 200 W/m^2. So how is this possible at emissivity = 0?”
Answer to 1) The green plates are at zero K for an emissivity of zero for the surface facing the source.
This is because the equations for energy balance for the system are not applicable when you have no energy leaving the system, obviously.
Answer to 2) Again for an emissivity of zero the green plate is not generating 200 W because it as at 0K. All the energy being generated by the source is being reflected back to the source by the emissivity =1 surface of the green plate.
“This is because the equations for energy balance for the system are not applicable…”
Eli’s math is not applicable. Now you’re getting it.
As explained on several occasions by myself and others,the energy conservation equation for the sytem is not applicable for the unique case when the emissivity is exactly zero.
So repeat from above, until it sinks in,
“This is because the equations for energy balance for the system are not applicable when you have no energy leaving the system, obviously”.
For the infinite number of possible values for the emmissivity between 0 and 1 and including 1, the totality of the “Eli Rabbitt” equations holds as, for these cases, energy is both entering and leaving the system.
Do you understand why the equations include the word balance?
Maybe not.
Slight correction to my comment,
https://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-415172 .
The last line should read as follows,
“source by the emissivity = 0 surface of the green plate.”
Sure, the temperature of the green plates get hotter and hotter and hotter, whilst always emitting 200 W/m^2, except when you actually get right down to emissivity of zero, when they suddenly become zero K, and emit nothing.
Radiative insulation by a black-body material means you can double the output from a heat source, and with a material at emissivity 0.5 you can quadruple it.
It’s always great to know what you people are prepared to defend.
“Sure, the temperature of the green plates get hotter and hotter and hotter, whilst always emitting 200 W/m^2, except when you actually get right down to emissivity of zero, when they suddenly become zero K, and emit nothing”
Yes this the behaviour of a function that has a derivative that asymptotes to negative infinity. At the same time the function that describes the temperature of the source asymptotes to positive infinity.
“Radiative insulation by a black-body material means you can double the output from a heat source, and with a material at emissivity 0.5 you can quadruple it.”
Yes correct.In terms of temperature, for a theoretical blackbody insulator the temperature increase is 19% while for an emissivity 0.5 the increase is 41%. Try wrapping yourself in a reflective space blanket if you want to se the effect for yourself.
See? They actually defend it.
Maybe DREMT is right.
I may have to get used to the current zeitgeist and accept the rule of the idiocracy.
On the topic of idiocracy, maybe DREMT could, rather than confused by theory, try my suggested experiment. Wrap yourself in a thermal blanket for a couple of hours. Monitor your core temperature with a thermometer (rectal for accurate measurements) and see what happens. Stop if your core body temperature exceeds 105F. It is best to the perform experiment on a cold day.
Remember to wash the thermometer thoroughly if you plan to use it again orally.
Back to blankets again…yawn..,
Yes, blankets again! They are a very good analog to the 3 plate problem.
How do you think a thermal foil blanket works? As you seem reluctant to conduct the experiment I suggest, maybe you should go back to theory.
p.s..Anything you say, in particular your absence of an answer, will be highly incriminating and will be held against you.
Silence and/or evasion is not golden in this case. You can however fall asleep and answer in your own time.
“p.s..Anything you say, in particular your absence of an answer, will be highly incriminating and will be held against you.”
Desperate.
So we can conclude from your non substantive response that you have no idea about how a thermally insulating blanket works.

https://en.m.wikipedia.org/wiki/Space_blanket .
“Even so called “radiation” blankets…” was part of the comment linked to.
Didn’t read it all. Did he discuss how these work on a spacecraft in a vacuum by any chance?
I see you’re already switching analogies…
No,sticking with the space blanket analogy. It has “space” in the name for a reason. Can you guess why?
Well, this is what I had for your original analogy, as you wrote it, assuming the person was wearing the space blanket on Earth:
There is a theoretical internal body temperature a person could have, if their only means of losing heat was from radiation, and if we assume just for the sake of argument that they cannot die from having this internal temperature go too high. Now add into the equation air, conduction and convection, sweating etc, all the other ways a body can lose heat. Their internal body temperature is now well below that theoretical level. Insulation, of any kind, can not raise the temperature of the heat source beyond that theoretical level (and not just because of death!). That’s what I mean by “insulation can’t raise the temperature of the heat source”. That is basically also the point Rosco is making in the linked comment.
There is a reason these discussions always involve the plates in vacuum.
If you are suggesting the space blanket raises the temperature of the heat source inside the spacecraft, then that would be a no-no.
DREMT, in the unlikely event you are right, I am not sure why NASA put in the effort to invent the space blanket. If you go to the Smithsonian and see the Apollo 11 lunar module it is covered in reflective multilayer metallic foil. Why did they do that? Here are some expert commentary on the matter.
https://www.quora.com/Why-does-the-Lunar-Landing-Module-look-like-it-is-wrapped-in-golden-aluminium-foil .
DREMT, you are also clearly convinced that reflective blankets cannot increase the core temperature of a human being.
In light of your belief I hope that this never happens to you. If you ever end up stranded in the North Atlantic in a dinghy and a rescue party drops you a metallic reflective blanket from a helicopter, please don’t throw it overboard. It would be a terrible way to learn the lesson.
By the way , why is this product available for sale?
https://www.amazon.com/Primacare-Foil-Mylar-Rescue-Blanket/dp/B000Y8Q4G2
Any ideas?
“DREMT, you are also clearly convinced that reflective blankets cannot increase the core temperature of a human being.”
Try reading my comment again, more carefully this time.
Ok excellent news! I am glad we agree that a space blanket can raise the core temperature of a human via the energy reflected back by the inside reflective surface of the blanket ( along with convection).
So why did you make this claim?
“insulation to your home doesnotmake the heating element within that heater warmer. Adding the casing around the heating element doesnotwarm the element via back-radiationorreflection.” , see –
http://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-415060 .
I’ve already clarified what I mean by “insulation can’t raise the temperature of the heat source” or “insulation can’t raise the output of the heat source”, in my comment of December 14th, 9:47pm.
Except the phrase “insulation can’t raise the output of the heat source” doesn’t appear in your 9:47 comment. Try again DREMT.
Ok so you and this Rossco fellow are saying that it can raise the core temperature, but there is a limit. Agreed.
So you are completely contradicting.
insulation cant raise the temperature of the heat source or insulation cant raise the output of the heat source,
DREMT, what a tangled web you tried to weave. Sorry about the boot coming down.
It’s easy for some to get confused when you have convection etc added into the mix, as Rosco mentioned. That’s why the GPE being in vacuum conditions makes it all a lot simpler. There, your blue plate is quite clearly having both its output and its temperature increased by insulation, which you have yourself agreed, and which Ball4 and myself agree is not possible.
No tangled web, no contradictions, as long as you pay attention to what has been said.
“..its temperature increased by insulation, which you have yourself agreed, and which Ball4 and myself agree is not possible.”
No DREMT, you have it wrong yet again, I disagreed with you.
Ball4, do you think it is possible for the blue plate temperature, or associated radiative output, to be increased by adding insulation?
Ok DREMT, even you must surely realise the implication of this, is that in a vacuum, 244K for all 3 plates, no longer holds.
Finally we have agreement.
Maybe you should add an erratum to all your previous posts stating this. You should try and do this as quickly possible. As I know, humble pie is best consumed hot. Preferably after heating in a well insulated oven.
“Ok DREMT, even you must surely realise the implication of this, is that in a vacuum, 244K for all 3 plates, no longer holds.
Finally we have agreement.“
Incorrect.
I would say please elaborate, but why bother.
Now that DREMT has nowhere to hide, he is trying the old diversionary splitting exercise.
I think I have learnt a couple of things
One was that it got me to brush up on my thermodynamics which I hadn’t thought about much since my undergraduate days.
Secondly I shouldn’t post late at night.
Thirdly it can be difficult to nail down a charlatan who just throws up diversionary chaff when cornered. We have seen the full gamut here from Gish Gallops , straw men, to pretending he can not answer because he is too bored , one word assertions and answers, to attempts at splitting.
It has been amusing at times and I have tried to hone my skills at mockery because, if anyone deserves a good mocking it is this fellow.
“I would say please elaborate, but why bother”
Yes, why would I bother to elaborate when you can just scroll up and read through what’s already been written?
I would ask you to elaborate on where you see agreement, but why bother?
P.S: I see Ball4 has gone very quiet. That’s because unthread I wrote, ridiculing the position that Team GPE has to defend: “insulation can increase the output from a heat source.”
and he responded:

“No DREMT. That takes more fuel. Added insulation to your home economizes on fuel.”
Heated by its own reflected radiation? What a strange idea. Do you get warmer standing in front of a mirror, Mike? I expect you do that a lot, so you should know.
Being warm blooded, the obvious answer is yes. In your case probably not.
Same goes for a reflective thermal blanket.
Wow, Mike. So if you stand between two mirrors, you must get super hot.
Hot and bothered. Don’t try it at home folks, particularly with infinitely high mirrors.
Never mind infinitely high mirrors…when you walk through one of those house of mirrors you must get unbearably warm. Tell me about your many experiences getting hot in front of a mirror. Don’t worry, I don’t shock easily.
Last time I was in a hall of mirrors, I collapsed. It was due to vertigo, just before the heat stroke set in.
On a similar note, you should try and build yourself your own personal integrating sphere
https://en.m.wikipedia.org/wiki/Integrating_sphere
You could even build it out of ice cubes. So the ice doeesn’t melt, build it in the Arctic with the help of the locals. These locals prefer to sleep in their integrating hemispheres, even on rain free and windless nights.
By the way DREMT, who was the first idiot here who claimed cold objects cannot heat warm objects via insulation? G* I think?
Probably one of you lot.
Nope, g* acompanied by Robbo were the first in the idiot lineage. Go back to October 2017 if you need confirmation.
I doubt that, as those guys understand what “heat” means, and what “insulation” does. It’s you guys that are confused, and/or prone to attacking straw men, so I will stick with “probably one of you lot”.
Was there anyone other than the exiled gang of 4,5 or 6 ( number depending how you count sock puppets) who claimed cold objects cannot heat warm objects via insulation?
If you can find anyone that you have been arguing with that that supports the claim, let me know.
You are sick.
The depiction is here.
https://i.postimg.cc/mgt4VZBQ/three-plates_DREMT.jpg
The numbers in your graphic don’t add up. There’s 800 watts going into the Blue plate but only 400 watts leaving.
The evasive manoeuvres begin…
DRsEMT, Pointing to the facts about that graphic post is not an evasive maneuver. Unless you live in the trumpian world of disinformation..
…and there’s another version of that graphic with those additional green arrows you laugh about so much…and it’s all been discussed a dozen times already. Bringing it up again is an attempted evasion from the sticky situation Team GPE finds itself, here:
https://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-414891
There is no “sticky situation” here.
There is only an inability to recognize the different between “emissivity is zero” and “the limit as emissivity goes to zero”.
Once MikeR has set his spreadsheet right again, for the twelfth time, you can have a chat with him about that if you like.
E.Swanson,
Notice DREMT’s trademark avoidance. He links back to a previous comment that does not contain a graphic or even refers to a graphic.
More unadulterated b.s..
With respect to the graphic, not only as you have pointed out, does his blue plate have more energy arriving than leaving, but his green plates also have more energy leaving than arriving. The only energy balance equation that is satisfied, is for the system as a whole.
I guess getting 1 out of 3 energy leaving balance equations correct is good going for DREMT. Maybe he can try and get 2 equations right next time. Baby steps.
No matter how many times you try to change the subject back to something that has been talked over and over and explained at length already, it’s not going to happen. I’m not going to discuss it again. I don’t care how many people try and in how many different ways they try it. It’s been done already. Your solution is what is on trial. You are the ones arguing that insulation raises the temperature of the heat source.
I linked to the comment that explains the particular situation you are trying to avoid, here.
“Your solution is what is on trial. You are the ones arguing that insulation raises the temperature of the heat source.”
The trial is over. DREMT lost. The home insulation, heat shield, and 400W incandescent light bulb industries exist – to do what DREMT insists cannot be done.
DREMT should rely on experiment in this field not rely on the field of his sophist dreams.
More fluff from fluffball. Nothing new.
DRsEMT It’s a very well known fact that adding more insulation around a body which is being supplied with a constant power source will cause that body’s temperature to increase, other things being equal. DRsEMT distorts this by referring to “the heat source”, not an externally heated body, such as the Blue plate or the Earth.
Then DRsEMT admits defeat by crawling back to the schoolyard to rant and rave.
“DRsEMT distorts this by referring to “the heat source”, not an externally heated body, such as the Blue plate or the Earth.“
We’ve been discussing the 3-plate scenario, in which the blue plate is the heat source. You may now rant and rave.
DRsEMT, NO, the Blue plate isn’t the “heat source”. The Blue plate is being supplied energy from an external 400 watt source, which “heats” it, causing it to emit thermal IR EM radiation.
I will respond to just this one comment today, as poor old Swanson seems to be in denial.
It’s a thought experiment, Swanson. Try using your imagination. In the 2-plate scenario, you have the sun, the blue plate and the green plate. I assume you can agree the sun is the heat source!? In the 3-plate scenario, there is just the blue plate, and the two green plates. So what is the heat source? It’s the blue plate!
…and if you still have a problem with that, again: it’s a thought experiment. Whatever you need to do inside your head to think of the blue plate as a heat source, whether it needs internal nuclear reactions, like the sun, or whatever else…do it. Imagine the scenario with the blue plate as the heat source. What are the temperatures of the green plates, and what is the final temperature of the blue? Your twisted logic inevitably leads you to conclude that the passive green plates raise the temperature of the heat source. If not, explain why. Say what the temperatures of all three would be.
Great news! Ball4 and I are in agreement. So it’s now currently the two of us arguing against Team GPE:
https://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-415554
The diagram needs arrows that represent reflected light. Then it all works.
Each green plate emits 200 watts to the blue. This energy is then reflected back and absorbed.

Its all about the colors. A 244 K green plate will absorb energy from a 244 K blue plate, but not the other way around! This is common knowledge to anyone who has studied at Huffypuff U.
Why do I always have to talk to about seventeen different people? I mean it shows how desperate they are, but it’s a little OTT.
“Good job here, DREMT. Your answer agrees with standard thermodynamics as taught in physics classes and as employed by practicing engineers around the world.
At 345K, the blue plate has a total output of 1600 W and a total input of 1600 W. The net power is 0 W, so its temperature will stay steady @ 345 K.”
Yep, for once, good job, DREMT.
Now we await how you will debunk yourself…
Maybe it’s your personality that rubs people up the wrong way.
Have you considered that possibility?
Referring to DREMT of course.
Sure, it must be my habit of responding to unpleasant people in kind that leads to this concerted team effort to relentlessly attack me personally and everything that I say down to the most ridiculous, nit-picking detail. It’s definitely nothing to do with the things that I’m saying…
Ok DREMT, I will invoke the Mercy Rule and will now try to resist the urge to mock you. I hope I can resist but you make it so difficult.
Perhaps, also if you responded with answers to the “nit-picks”, such as the Laws of Thermodynamics, you may engender more sympathy for your plight.
Mock away. My care factor remains at precisely nil.
Ok, excellent news. Might be time to wheel out the heavy artillery.
Make yourself look as bad as you want. That’s what this is all about, after all. A prolonged demonstration of what you people are, how you operate, what you are prepared to defend, the depths to which you will sink, etc. Please do carry on.
Yes, DREMT . I suspect I wouldn’t get reviewed well by yourself. However I might get different views from those many others that contribute here. Particularly the 17 or so who have made their views about your competencies well known.
I note that you have recently relapsed into full on PST troll mode. It is unfortunate because that behaviour is even more likely to make people view you with disdain.
I understand that you need as many friends as you can have as no-one appears to have rushed to support your views. Needlessly creating more adversaries in these debates is silly and it makes you like a very sore loser. Or just a loser .
That’s the stuff…
Happy to oblige.
Desperate? I was just admiring your work.
See?
“Send in the clowns…”
Huffy,
grass looks green because the colors yellow and blue get reflected back to our eyes.
So, maybe the blue plate is actually absorbing the yellow component of the green plates energy, and just reflects the blue half?
Throws a monkey wrench into the whole situation!!
I’m sorry that this is all over your head.
Snape: “grass looks green because the colors yellow and blue get reflected back to our eyes.”
Illuminated by what source? The sun? If so, then radiation of all colors of the visible spectrum enter our eyes from looking at grass in the clear daylight; mostly as LW (~95%) only about 5% as SW. Our brains assign the color humans know as green to interpret that signal.
Apparently, you have not pointed at a patch of grass with a Photo Research SpectraColorimeter Model PR-650 SpectraScan, which can measure radiation from 380 nm to 780 nm in increments of 4 nm with a bandwidth of 8 nm. If you do some research, you might find someone that has done so & can then examine the instrumentally measured spectrum.
I stand corrected. Just trying to figure out why that blue plate is so dern persnickety.
😏
I’m sorry that this is all over your head.
Huffy
I was on a blog where I was personally insulted by a half dozen people. If I ever tried to return the favor, the moderator would remove the comment and issue a warning. Other comments would disappear at random.
At least here we can have an open conversation.
I’m sorry that this is all over your head.
No worries.
Looking back over my recent comments …….. same routine I went for a couple of years ago. Pathetic.
See ya, huff
Well, next time maybe you could try a different routine. There’s no need to be so hard on yourself.
Ok, without looking upthread too carefully, Ive thought about what might happen as the emissivity of the green plates approach zero.
Weird. Longer and longer to warm. Eventually trillions of years to warm even one degree. On the other hand, it would have to get ridiculously hot in order to emit 200 w.
So, warming for what approaches eternity.
At zero emissivity, it simply stops at whatever temperature it had reached time wise.
That doesnt address the blue plate, which would have been getting hotter and hotter as well, with continuously greater input to each plate.
Putting those two ideas together is tough.
Am I close?
Sorry, warming until each green plate emits a total of 400 watts,
I’ll just leave this down the bottom here, as well:
https://principia-scientific.org/light-recycling-disproves-greenhouse-gas-theory/
I love this piece of work. I also love standup comedy.
Hughes is not actually doing a experiment, thankfully, but has conducted a literature review.
The experimental arrangements are incadescent sources that are back illuminated via reflectors. No evidence (unspecified) of a temperature increase was found. Finally there was a claim that the globe would explode if “light recycling” can occur.
The major overwhelming issue with this is the use of a resistive incadescent source. These are ohmic resisters with a positive coefficient of resistance. In other words any increase in temperature of the filament due to back reflection will cause an increase in resistance of the filament. For a voltage regulated source I = V/R and the current and power will drop, contrary to Hughes intuition. This is a classical negative feedback situation so in this case the temperature of the source will not increase with back refection. Thermal runaway cannot occur and the globe will not explode.
In contrast if a material has a negative coefficient of resistance such as a semiconductor , then yes the temperature would go up and thermal runaway can and often will occur. So if he conducted an experiment with an LED and covered it with tin foil then there is a good chance he may get the desired destructive result. He would also have to disable the current regulation circuitry of the LED’s power supply.
Finally, the inescapable conclusion of this piece of work is that the author is totally clueless.
Summary: despite what has been argued many times before, MikeBlah happily agrees that you can’t increase the temperature of a filament by reflecting energy back to it, and instead now claims you need an LED with the current regulation circuitry of the power supply disabled.
If you are interested in a Myth Busters type explosion, then you may be able to achieve it with a source with a positive coefficient of resistance such as an LED.
With his demonstrated experimental skills, Hughes should try it, preferably with a tin foil hat on.
Hughes ignorance is amazing but in line with the all the other crap on that web site.
The original author makes a large number of mistakes. Mike makes a few other mistakes. There are too many to address each one but here are a couple.
FROM LINK:
“An unsuccessful example is the Duro-Test”
No, they were commercially produced, and were scientifically successful — about 2x as efficient as regular incandescent bulbs. The only think ‘unsuccessful is that these gains were apparently not worth the extra production cost and people did not buy them. [Current LED bulbs are about 6x as efficient as incandescent and not much more expensive, so they are both a scientific and a commercial success.)
“its IR heat mirror is reflecting in a globular fashion which is sending heat back not to the centre where the filament is, because to do that you would need parabolic reflectors.”
No, a parabolic reflector is designed to send light out in a parallel beam, NOT back to the source. A spherical ‘globular’ shape is in fact the correct shape to reflect light straight back to the source.
From Mike:
“any increase in temperature of the filament due to back reflection will cause an increase in resistance of the filament. For a voltage regulated source I = V/R and the current and power will drop, contrary to Hughes intuition. This is a classical negative feedback situation so in this case the temperature of the source will not increase with back refection.”
Not quite. Yes, the resistance will increase. Yes the electrical power input will decrease. No, the filament will not stay the same temperature. The reflection returns some energy, which means the filament loses less energy. As an extreme example, a bulb fully coated with a material like shiny aluminum (ideally in side the bulb) will have no light getting out, and a much hotter filament than an uncoated bulb.
This would be akin to (a blue plate with 400 W in surrounded by a green plate with emissivity = 1) vs (a blue plate with 300 W in surrounded by a green plate with emissivity = 0.1). The second has less power in but a higher temperature.
BOTTOM LINE. An incorrect objection to an incorrect statement does not make the statement true. The original work is so flawed that it is — as Fermi might have said — “not even wrong”.
Bottom line: reflecting the energy back towards the filament does not make the filament hotter.
Yes DREMT it doesn’t in this case as Tim (not Tom) explained.
This is a consequence of the negative coefficient of resistance of the filament and not the absence of reflected radiation.
Thanks Tom,
I am in total agreement with your analysis. Yes, the temperature will drop to a new steady state value.
There will be no positive feedback causing thermal runaway as per the Hughes bit of nonsense.
Bottom bottom line: it has been argued many, many times before, by these people, that energy reflected back to the filament will warm the filament. Despite the criticisms, Hughes’ literature review just forced them to admit it doesn’t happen. Now they’re on about LEDs instead.
Tim: “a much hotter filament” happens.
DREMT: “Hughes literature review just forced them to admit (a much hotter filament) doesn’t happen.”
DREMT’s reading comprehension approaches in the limit zero.
DREMT says: “Bottom line: reflecting the energy back towards the filament does not make the filament hotter.”
MikeR says: “Yes DREMT it doesn’t in this case as Tim (not Tom) explained.”
Ball4 says: “DREMT’s reading comprehension approaches in the limit zero.“
MikeR’s “in this case” is important for DREMT to include in any attempt to improve his poor reading comprehension above in the limit zero.
So, which case is he referring to?
I’m well aware that Tim said what he said…but Tim says lots of things that aren’t true. I like to pick up on the times that they butt heads and trip over each other, because occasionally something honest slips out…and let’s face it, that’s the only way it’s going to happen.”
A few comments directed toward various statements above.
1) Infinity, zero, and taking limits are difficult concepts.
Consider our blue & green plates starting at 0 K. As emissivity of the green plate drops, the final temperature of the green plate increases, but the rate at which it starts to warm decreases. In the limit as emissivity goes to zero, the final temperature increases toward infinity, but the initial warming rate goes to zero.
If we try to set emissivity exactly to zero, we are left with a conundrum — that the plate warms infinitely slowly, but reaches an infinite temperature. In this case, you have to dig deeper mathematically. In our case, the infinitely slow warming wins, and even after an infinite time, the temperature does not change for the green plate.
2) Human bodies are terrible examples for anything dealing with temperatures, heating, insulation etc.
Warm blooded humans have multiple mechanism to regulate temperature. We can put on or take off clothing. We can shiver to stay warm or sweat to stay cool. We can stand in the sun or stand in the shade. Our metabolism can speed up or slow down. We can run a fever. We can die.
There is no “theoretical temperature” for a human body. A healthy body will try to maintain a given temperature of about 98.6F + 37C, but this is not some “theoretical limit” like for the blue plate. If you keep exercising on a hot day, your body WILL continue to rise above 37 C. The only ‘limit’ is when your body stops working.
Please stop using humans as any sort of analogy for the earth or for how insulation works.
3) Incorrect application of a theory does not invalidate the theory.
Mike made an error or two in his spreadsheets when he tried to apply the (correct) rules for thermal radiation. DREMT made an error or two with handling zero and infinity and limits. There have been some wild errors from people misapplying the rules for thermal radiation to think that these rules imply that you can cook a turkey with ice.
These are not trivial calculations. If you think there is an error in a fundamental fact or equation find in textbooks, your first thought should always be that *you* are wrong, not the textbook. Sure, you might be like Einstein discovering Relativity — but it is highly unlikely.
Tim,
Many thanks for your comments but I think there may be a slight misunderstanding. Clearly the climate systems and insulation are different to the human body but still share some common characteristics.
Consequently , I don’t think it is too far fetched to relate the human body’s temperature regulation to a system regulated by a thermostat, albeit a very complex one. For instance there are various active regulatory systems involved in thermal homeostasis and the set point varies dependent on a large diverse range of factors (diurnal, hormonal etc., etc.) but I think the principles of regulation , such as negative feedback are similar.
A good read regarding this is the following
https://www.ncbi.nlm.nih.gov/books/NBK541107/
Another point to note, in the absence of clothing (or a blanket) radiation is the most significant source of heat loss for a human accounting for approximately 60% of the total.
The main point I was trying to make was that, despite the complexity , the space blanket can , and is often used to increase core body temperature when required. The thermal physics underlying these blankets involve reflected radiation, convection and conduction (not necessarily in that order). Clearly space blankets would not be typically made from highly reflective metallic films if the sole mechanisms were simply convection and conduction.
Taking the analogy one step further, and possibly too far, the relationship to the 3 plate system is that the presence of surrounding reflective surfaces will decrease heat loss and thereby increase the steady state temperature (for the blue plate). Similarly for the human body, the back reflection from the inside of the blanket allows a higher set point to be obtained (particularly compared to an inadequately insulated human in a dangerously cold environment).
I’ll write it out again, a little clearer this time, and applicable to anything, rather than trying to discuss the complexities of the human body specifically.
There is a theoretical temperature a heat source could have, if its only means of transferring energy is via radiation. So, this is with the heat source in a vacuum. Let’s call this temperature a). Now introduce air surrounding it, so that you also have conduction and convection, etc, other ways a heat source can transfer energy. The temperature of the heat source is now below that theoretical level. Call this temperature b).
Insulation, of any kind, cannot raise the temperature or radiative output of the heat source beyond temperature a). That’s what I mean by “insulation can’t raise the temperature, or output, of the heat source”. That is basically also the point Rosco is making in the linked comment further below, that I posted at 2:39 am.
There is a reason these discussions always involve the plates in vacuum. In the 3-plate scenario, the blue plate is the heat source. The blue plate, alone in perfect vacuum, is at temperature a). 244 K. Adding insulation cannot raise the temperature of the heat source (blue plate) beyond that.
I’m not saying its temperature is fixed at 244 K. The electrical input of 400 W is what is fixed. However, insulation cannot raise the temperature or output of the heat source.
“Insulation, of any kind, cannot raise the temperature or radiative output of the heat source beyond temperature a).”
Translation: the 1LOT is faulty, metal foil on insulation materials doesn’t work, and IR blankets for emergency use should be discarded.
DREMT doesn’t know what DREMT is talking about.
The 1LOT is not faulty, metal foil on home insulation materials works and emergency IR reflective blankets are important for some uses simply because they can raise temperature beyond a). This has been proven in tests by DR. Spencer, DREMT has no experiments only assertions. They cannot however raise the output temperature to surroundings so that part is correct.
“Translation: the 1LOT is faulty, metal foil on insulation materials doesn’t work, and IR blankets for emergency use should be discarded.”
No, Ball4. These things can be useful to keep the temperature of the heat source above temperature b).
Or, if you are trying to keep the temperature of something other than the actual heat source itself warmer than it would otherwise be, which is by far and away the most common use for insulation.
By the way, I appreciate your help in all this. Upthread I wrote, ridiculing the position that Team GPE has to defend: “insulation can increase the output from a heat source.”
and you responded:
https://www.drroyspencer.com/2019/12/uah-global-temperature-update-for-november-2019-0-55-deg-c/#comment-415564
“No DREMT. That takes more fuel. Added insulation to your home economizes on fuel.”
“These things can be useful to keep the temperature of the heat source above temperature b). I appreciate your help in all this.”
Yes. Glad to help DREMT understand. These are the same physics as the atm. GHE on Earth global ~33K near surface brightness temperature b) increased over system output brightness temperature 255K.
Now, you can go on to learn that temperature a) can be increased in a vacuum by adding those same things which is why NASA uses them & some call them space blankets. However, the spacecraft system median output temperature cannot be increased by them.
Or call up NASA and explain they are wasting money and mass for insulation that does not work to increase internal component energy source temperatures when illuminated by starlight over those temperatures in a near vacuum without such insulation when illuminated by starlight.
You should also go on to learn 1LOT dictates if you are trying to keep the temperature of the actual energy source itself warmer than it would otherwise be, all things equal, which is not far and away the most common use for insulation. Far and away the house living areas want to be kept warmer in the winter by insulation not the furnace although that is also a consequence unless the added insulation to your home is used to reduce fuel consumption (a case of things not equal before and after added insulation).
Complete gibberish.
More hand waving from DREMT.
No formulas and no math.
More hand-waving from Svante, Tim Folkerts, Ball4 and MikeR.
No formulas and no math.
Just proper experimental evidence backed by hard won theory.
Thanks for setting Svante straight, Ball4.
Yes, correction:
No formulas, no math, and no experimental evidence from DREMT.
Lie after lie after lie, from Svante.
1) Try to explain it to Snape. He seems to be struggling with the nonsense you are spewing…and rightly so. It’s nonsense.
2) You have completely misrepresented the point I was making with the analogy, which MikeR introduced, by the way.
3) The only error I made with “handling zero and infinity and units” was not telling you beforehand I was aware of the expression “in the limit to…” so that you were able to make your points as if you were teaching me something when in fact you were just dancing around the problem, as always.
I think that’s about it.
@Tim
One point of disagreement. If our hands feel cold, its because they ARE cold. Its something weve all experienced, and weve all experienced the warmth that results from putting on gloves or mittens. We know the source of the warmth originates from our own body, and that there is no violation of the 2LOT.
For those reasons I think gloves, mittens, socks etc., are a useful example of insulation when arguing with the likes of Huffy and Flynn.
But true, not a good example when talking about limits.
(Pardon the lack of apostrophes!)
Snape, yeah there is some value in personal experience, but intuition can also be horribly wrong. I think the downsides in disucssions like this far outweight any advantages.
We are often discussing constant heat sources (like the sun or the blue plate), and humans are not anything like that. That can lead people to imagine the blue plate ought to be constant temperature.
Also, our bodies can be poor at judging temperature. If our hands feel cold … they might or might not actually be cold!
https://www.scientificamerican.com/article/cold-or-warm-can-we-really-tell/
[If our hands feel cold, its because they ARE cold.]
By that, I meant that when our hands feel cold they are well below our core temperature. Maybe 20 F lower.
@Tim
Youre probably right. It never seems to be helpful.

Plus ca change, plus c’est la meme chose.
I’d always advise people to read through all the comments.
The comment I Iinked to related specifically to Tim and Snape’s conversation.
I am not sure who this random Rosco is and why you have elevated him to an authority on these matters. I have not been able to find anyone by that name on Google Scholar. The only reference I could find was this one
http://www.roscotheclown.com/
The material in the link you provided made a convincing case that this is the fellow in question.
For example from Rosco.
“Terrestrial mammals have only one mechanism to preserve their body warmth – outside of hiding from the weather that is – and that is by the mechanism of their fur or feathers preventing convective heat loss of the air warmed by their body temperature. Obviously there is no radiative barrier.”
Last I heard humans are mammals. They have minimal fur or feathers (with the possible exception of Esau – I am not sure what the creationist viewpoint of this is).
The heat loss for a naked human in still air is predominantly by radiation (60% of the total heat loss). That is probably why emergency space blankets were designed with humans in mind.
Never a good sign for them when they have to play the man and not the ball. Trying to suggest Rosco is a creationist!? I’m not even sure what the point was…
…regardless, the comment is straightforward logic. An object loses more heat when there are more means by which it can lose it. So, if radiation is the only way (i.e if the object is in vacuum) it’s temperature will be higher (temperature a) than if there is an atmosphere present and you now have conduction and convection in operation (temperature b). Stands to reason. He is simply pointing out that insulation can help return an object’s temperature towards a.
We already know from both Hughes and Swanson’s experiments that the plates are warmer in vacuum, so there’s no point trying to pretend it isn’t true.
Yes my comment re creationists was just a rhetorical flourish. These repetitive exchanges can be so dull, I like to lighten things up.I am not sure what Rosco’s religious beliefs are, so if I have offended him, then pass on my apologies.
Yes heat can be lost by many means but for a human in still air, the loss by radiation is 60% of the total. Therefore the use of thermal blankets with reflective surfaces on both sides.
Additionally I agree the experimental results of Hughes appears, if believed, to support this for plates. I haven’t has a good look st Swanson’s experiment, but I will take your word on it.
Did Hughes also do the experiment with naked humans?
Glad you agree with the point being made.
Yes I agree for the particular point I think you are referring to. If convection and conduction are eliminated then heat losses by radiation are left over.
I do however strongly disagree with Rosco’s generalization. “Terrestrial mammals have only one mechanism to preserve their body warmth outside of hiding from the weather and that is by the mechanism of their fur or feathers preventing convective heat loss of the air warmed by their body temperature”.
Clearly this is not the case for humans who normally lack fur or feathers.
If you want to argue the point please go ahead.
I’m not sure why you can’t see the link between “fur” and human hair, but yes people tend to wear clothes, which Rosco neglected to add. Maybe because it was so obvious it didn’t need mentioning.
…or, more accurately, “reiterating”.
Yes I see a link, but human hair and animal fur are equally thermally effective?
My panting dog begs to differ. He also points out that unclothed humans lose 60% of their heat by thermal radiation. He is at a loss as to why you cannot understand this.
“Yes I see a link, but human hair and animal fur are equally thermally effective?”
No, hence why people wear clothes. As discussed by Rosco.
You’re missing the point, deliberately.
Good I am glad you recognise the difference between human hair and fur, a distinction that Rosco had do much trouble with.
Returning to the original subject of this thread and spawned sub threads, space blankets have highly reflective surfaces to reflect back body radiation. They are optimally effective for unclothed humans who lose 60% of their heat by radiation, not so much for animals with fur.
Returning to the original subject of this thread:

Combination of 2 and 3. Interesting move.
“Radiation trapped inside a cavity with a source of a known temperature does not cause run-away self-heating to infinity! It creates a blackbody spectrum with a wavefield in all manner of superposition with constructive and destructive interference with itself; it does not cause the radiation to spontaneously increase its own temperature spectrum or the kinetic temperature of its own source. Radiation is an electromagnetic vibration. This vibration interacts with matter due to electrodynamics and induces vibrations of corresponding power in the matter, in the molecules and atoms. The only power that radiation has to induce vibration in matter, and hence induce a temperature, is the power associated with its spectrum. There can be no other expectation than this. When the matter comes fully to “vibratory equilibrium” with the incident radiation, the radiation and the matter then simply oscillate with corresponding power – the matter emits exactly the power of vibratory energy that comes in. That emitted radiation is of the same power as that coming in, and nowhere in this process will the radiation do more work (i.e. induce a higher temperature) than it can given what its spectrum is, and nowhere in this process will the matter spontaneously vibrate at a higher “temperature rate” than the incident radiation, because the frequency components required to do so don’t exist and are never created.
Temperature is a measure of vibration frequency and the frequencies required for a higher temperature induction are simply not there, and they’re not spontaneously created, because there’s no reason for them to be. Trapped radiation inside a cavity simply resonates – it doesn’t change its own spectrum and it doesn’t change its own temperature and it doesn’t change the vibratory frequency components of its material source. All of this is what lead to Max Planck, blackbodies, and quantum mechanics. To deny this is absurd.

Maybe a little superfluous, but I did enjoy Tim and MikeR butting heads. Mike is always a little too keen to try to trash someone, and in his attack on Hughes he inadvertently let something important slip. Tim tried to cover but Mike bungled it again.
I enjoyed it to. It is good to get feedback from someone as knowledgeable as Tim Folkerts.
It is so much more pleasant than interacting with someone on the opposite end of the intellectual spectrum.

Insult acknowledged.
DREMT,
Is this entirely your own work? If not I have no idea where you lifted the majority of this from.
I do However agree with the general statement that Radiation trapped inside a cavity with a source of a known temperature does not cause run-away self-heating to infinity! “. The thermal runaway situation just describes what would happen for the theoretical and unrealistic case of infinite barriers which reflects exactly 100% of the radiation back to the source.
Certainly in a realistic case ,the cavity can increase the temperature of the source in comparison to when the cavity is absent. This is what the argument is about.
As for the rest of this garbage , it refers to interference which is largely irrelevant in this case as blackbody radiation is incoherent. If the author was referring to laser radiation in a cavity it might make sense but in this case forget it.
There is a reference to the temperature of the radiation. “Trapped radiation inside a cavity simply resonates it doesnt change its own spectrum and it doesnt change its own temperature” . From that statement alone it is clear that whoever generated this stuff has not been exposed to even a junior science class.
Temperature is a property of matter and not e.m. radiation .
For remedial education on this matter at a level that is appropriate see –

“DREMT, Is this entirely your own work? If not I have no idea where you lifted the majority of this from.”
It is Joe’s own imaginative, non-experimental disinformational work.
Joe used to post around here under the screenname shown in this link but that screenname was laughed off this blog & and the sophist Joe has returned under another alias or two…or three. The disinformation just keeps on coming! As Dr. Spencer writes: “it really does not matter that much to most alarmists or skeptics what the evidence shows.” Search on “infinity” for the start of this particular disinformational ramble.

Good pickup Ball4. Did you use plagiarising detection software?
With the exception of one paragraph indent and 5 words at the end, it is a just a cut and paste of the Joe Postma comment on WUWT. To deny this is absurd.

Was this battle part of Smokin Joe’s “War of the Vibrators”?
https://climateofsophistry.com/2013/03/08/the-fraud-of-the-aghe-part-11-quantum-mechanics-the-sheer-stupidity-of-ghe-science-on-wuwt/
Here’s where the quote actually came from.
MikeBlah said:
“There is a reference to the temperature of the radiation. “Trapped radiation inside a cavity simply resonates it doesnt change its own spectrum and it doesnt change its own temperature” . From that statement alone it is clear that whoever generated this stuff has not been exposed to even a junior science class.”
The “its own temperature” referred to is of course the temperature of the object. First sentence reads, “radiation trapped inside a cavity with a source of a known temperature does not cause run-away self-heating to infinity!”. Note that it’s “known temperature” and not “fixed temperature”.
I recommend everyone reads through all the comments at the link. It’s great to see “people” like the ones responding to me here getting the respect they deserve.
Trapped radiation inside a cavity simply resonates it doesnt change its own spectrum and it doesnt change its own temperature
The subject of this sentence is “Trapped radiation inside a cavity”.
The cavity will actually change the spectrum due to resonance. Modes will be excited for wavelengths that are divisors of the separation between the plates. There will be multiple modes such as the fundamental lambda and the harmonics, lambda/2, lambda/3 …. etc. (lambda is the wavelength).
There will be multiple fundamentals (and associated harmonics) whose amplitude will be modulated by the black body curve. These fundamentals are not in phase so the radiation is still incoherent like DREMT’s understanding of grammar.
MikeBlah has no understanding of “context”.
Ok, as this clearly not going anywhere, I will return to the provenance of Joe Putzma the author of this piece.
I was aware of Dr Roy’s lambasting of this guy but didn’t realize his fame has spread to other areas of the deniasphere, see –
https://okulaer.wordpress.com/2015/01/19/postmas-confusion/
and
https://wattsupwiththat.com/2019/06/04/on-the-flat-earth-rants-of-joe-postma/
When those who are ostensibly on the same side of the debate think the author you quote is an unadulterated idiot then, by inductive logic , I think you may be perceived in the same way.
Hence your abandonment by everyone else in the comments section here.
Whoa, the boot comes down. Again.
The author of your first link, who comments here under the name Kristian, is in the comments at the CoS link. He is merrily lending his support to Postma, along with many, many others, in a debate over something incredibly similar to the Green Plate Effect…
Is this the same Kristian, the photon gaslighter I interacted with over a year ago regarding the Eli Rabbett setup?
If so, I recall he begrudgingly accepted the conventional calculations and then waffled on interminably in his inimitable style. I am however pleased he has made up with Joe Postma. I am sure they will be happy together.
Check the dates, moron.
Perhaps I am confused. The two had a nasty spat in 2015 see
https://okulaer.wordpress.com/2015/01/19/postmas-confusion/
and kissed and made up in 2017.
https://okulaer.wordpress.com/2017/09/02/the-heat-issue-once-again/
Have I missed up something? What is the current state of their relationship?
I am not that great fan of soap operas but keep us in touch.
Yes, you apparently missed the original link, that I was referring to in my 2:25am comment.
https://climateofsophistry.com/2013/03/08/the-fraud-of-the-aghe-part-11-quantum-mechanics-the-sheer-stupidity-of-ghe-science-on-wuwt/
Yes I missed that one, so the bromance started way back in 2013. Looking at the comments section in that link from that era, you can see that they were awfully fond of each other.
I also note that you worship and adore Joe. I just hope you weren’t involved in their 2015 breakup.
Looking in the comments in that link from that era, six years ago, you can lots of people making the same arguments that have been made more recently by some against the Green Plate Effect. Eventually, most people get bored of repeating themselves, which is why there aren’t so many nowadays still bothering to respond to the exact same stupidity from “Team GPE”.
DREMT, there may be other reasons, other than boredom, why these people have absented themselves from the debate. Being laughed at incessantly can bruise a fragile ego.
Consequently I am amazed you keep coming up for more.
The only safe haven, for people like yourself, appears to be the climateofsophistry asylum where Joe and his acolytes amuse themselves.
“Being laughed at incessantly can bruise a fragile ego.”
Yet you’re still here.
Laughter is the best medicine and I always enjoy a good laugh, even at my expense. What’s your excuse for your continued presence here?
I wasn’t aware I needed an excuse. When people keep responding to me, it’s only polite to reply back. So here we are, in excess of 850 comments, and the same people still want a chat! It’s very nice of them. Perhaps they’re lonely? Not sure…but I’m here, anyway, if they need me. Which they seem to.
I think attributing all 850 comments to your presence might be a bit grandiose.
The real question is to why Dr Roy tolerates your presence. Maybe it is due to the volume of traffic you generate which may improve the page ranking of this site.
At first I thought that It was strange that you were not culled in the great purge of 2019. Your behaviour was just as obnoxious as the others but I realised the reason may have simply been as a result of the pseudonym you use. Banning your comments by keywords would have meant that commentary would have been even more difficult than it is at present. Such terms as emergency , moderation and team would not be available or require punctuation to pass the WordPress filter. Was this an inspired choice or just inadvertent?
The other point you raise is why you get so many responses to your comments . Firstly I must note that recently , as your support team has fled the scene or been banned, your comments have been reviewed adversely by all.
If they were aggregated via Rotten Tomatoes you would score a zero at best. I think that would correspond to a maggot filled putrid mess of a tomato.
Irrespective of this I think the type and quantity of responses you have engendered are indicative of how you first entered the arena many months ago with your incessant gratuitous PSTs (which you still unfortunately persist with). This combined with the ignorance you proudly display may account for all these adverse reactions.
As for myself, the disdain I often express with regard to your comments is partly instinctive. I have had the unfortunate experience of interacting with AntiVaxers, ChemTrailers and other assorted idiots. When I see delusional b.s., I call it as it is.
Yes, we did get rid of a few rotten App.ells. A great purge indeed.
AC D*, mp****er, g*r*n, Huff, MikeF , Robbo(?) and any others who I may have overlooked, versus a single D.A..
Sounds like it could have been worth it.
DREMT do you want to do a trade?
Who?
For you any Dalek will do.
No…I meant, who are these people you are talking about?
No idea personally. Maybe you could fill me in.
I don’t know who you’re talking about because I don’t think you’re saying their names properly. Try listing them out in full.
I thought I had short term memory loss but yours is even more impressive.
Bit difficult to name names under the circumstances. I can provide you with the links if necessary.
OK then.
Snape
I disagree with your opinion of Joe Postma. Have you ever tried to reason with this one? He is not as intelligent as you perceive. He is so into his own teachings he will not attempt to challenge his views and attacks anyone who might dare point out the many flaws in his reasoning.
There is no way I could believe this person to be rational, intelligent or logical. He seems far worse than the fanatics on Skeptical Science. I think he is about the same mental fanatic state as a Greta just on the opposite pole. Read his responses to some intelligent posters that dare question his opinions.
Norman, Snape 4:07pm was being sarcastic.
OK, so let’s go through Team GPE’s “Greatest Hits”:
The Accordion of Heat:
2-plate scenario: plates pressed together, both 244 K. Slightly separated, up goes the blue plate to 262 K, down goes the green to 220 K.
3-plate scenario: plates pressed together, all 244 K. Slightly separated, up shoots the blue plate to 290 K! The greens chill out at 244 K still.
The Magic Insulators:
3-plate scenario: the blue plate is the heat source. Alone, in an infinite vacuum, no other heat sources in existence, it comes to 244 K. Input is 400 W.
Slap a couple of BB plates into existence, slightly separated, either side of it.
They don’t just get warned to the temperature of the blue plate. Oh, no. That would be far too obvious…
With BB “insulators” – 400 W input leads to an output from the blue plate of 800 W! Impressive.
Emissivity 0.5 insulators – 400 W input leads to an output from the blue plate of 1600 W! Stupendous.
Then, to cap it all off…as the emissivity of the green plates decreases, the green plates warm indefinitely, whilst always emitting 400 W. Of course, until you get down to zero, when they are suddenly at 0 K, emitting nothing.
Emissivity 0 insulators – 400 W input to the blue…infinite output!
That would all be so handy if any of it were true. Oh well.
Now that DREMT has outlined his final (hopefully) position statement, I think I might do likewise.
I will, unlike him/her/they/it , will also discuss DREMT’s preferred version of the 3 plates which for good reasons, he tries to avoid .
Firstly , here is my preferred version, for ε = 0 for the green plate
https://i.postimg.cc/J454kTT1/Three-Plates.png
And ε>0 and ε<1 for the green plate (both sides).
https://postimg.cc/474JKwtM
For the, theoretical only with a limiting case of ε = 1 (i.e. green plate is a hypothetical perfect mirror).
https://i.postimg.cc/SQVnb2pC/three-plates-Emissivity-of-1.jpg
Here is DREMT’s nightmare before Xmas version for all values of ε
https://i.postimg.cc/4N3qk7TH/3-plates-DREMT-nightmare.png
This is what DREMT has attempted to evade and divert from. If he can’t balance an equation, what hope is there for this unfortunate.
I am not sure I need to further elaborate, and accordingly the prosecution rests and we can now leave the debate to the court of public opinion.
I guess DREMT can plead insanity as his defence and could dress as a dragon slayer, with a tinfoil hat to keep his head warm, and then claim he was a victim of Postmanic delusions. This could explain what caused him to channel Postma’s deranged ramblings.
In that case, if the defence also presents all of his comments here, no jury would convict on that basis but he may be involuntarily confined (preferably with no access to a computer).
Annoyingly the lower case epsilon symbol for the emissivity didn’t copy and paste correctly in the above! However I am sure everyone gets the idea.
Even more annoyingly, the emissivities are also labelled incorrectly in the text (my fault). Of course they should read emissivity =1 for a blackbody and emissivity =0 for a whiteboard (mirror).
The joys of early onset dementia.
The radiative heat transfer equation has a term for the blue plate, and one for the green. At green plate emissivity 0, the term for the green plate no longer applies. All you are then left with is the “one term” SB Law equation for the radiative output of the blue. The blue plate is a black-body, and for such an object emitting 200 W/m^2, the corresponding temperature is 244 K. So, for all values of green plate emissivity, the blue plate is at 244 K, emitting 200 W/m^2.
To a simpleton, everything appears simple so I will also keep it at a simple level that is appropriate for you.
A single isolated plate (blackbody) with 400 W input will emit 200 W from each side and be at a temperature of 244 K. We are all in agreement with that.
The addition of plates adjacent (but not in thermal contact) will obviousy (minimum requirement of half a brain) have an effect on the original plate. Your belief that these plates will not be perturbed at all by the presence of these adjacent plates (infinitely high or otherwise) is to put it, in the most polite terms I can, is totally bizarre.
In your simple minded view, the three plate experiment is actually a one plate experiment!
I think we have had enough of this nonsense, I think we can all go home now.
I was just correcting you on one of your misrepresentations. If you’ve had enough, nobody’s keeping you. Cheerio then.
Lets look at DREMTS greatest hits.
DREMT: It is “far to obvious” that heat should magically flow from blue plate to green plate when both are 244K, in violation of the laws of thermodynamics.
REALITY: With excellent thermal conductors (eg thin plates of aluminum), yes all would be ~ 244K when pressed together (but of course slightly warmer in the middle so that 200W/m^2 of heat can flow from warm blue to cool green). The poorer the conduction, the higher the temperature of the blue plate.
With no conduction and only radiation, then the temperature difference must be larger to produce the requisite heat flow. in this case, 290K in the center
DREMT: “With BB “insulators” – 400 W input leads to an output from the blue plate of 800 W! Impressive.”
REALITY: With BB heat shields, the net output from the blue plate will be zero at steady-state. There are two equivalent ways to describe the situation.
a) 400 W electrical input plus 400 W IR input leads to 800 W output.
b) 400 W electrical input leads to 400 W net IR output.
DREMT: as the emissivity of the green plates decreases, the green plates warm indefinitely, whilst always emitting 400 W.
REALITY: There are multiple misunderstandings here.
1) The green plates always emit LESS than 400 W total (200 W each side). Initially, they emit 0 W. Only if/when they are in a steady state will they emit 400 W
2) For any non-zero emissivity, there there is a transfer of energy from blue to green and a final asymptotic solution for temperature. The lower the emissivity, the slower the initial transfer and the longer until the temperature approaches the final steady state solution.
3) For zero emissivity, the nature of the problem changes. There is no transfer from Blue to Green. The blue plate continues to warm for ever, and the green plate never warms at all! This is perfectly in line with the previous conclusions. As emissivity drops the initial warming rate of the green plate drops; if the emissivity were exactly zero, the intial warming rate would be zero (and the warming rate would be zero forever!)
DREMT: “Emissivity 0 insulators – 400 W input to the blue…infinite output!”
REALITY: this is the same misunderstanding as before. the correct answer is 400 W input (electrical) and ZERO watt net output (IR), allowing the blue plate to warm forever. Or 400 W input, infinite IR output and infinite IR input if you prefer.
“It is “far to obvious” that heat should magically flow from blue plate to green plate when both are 244K, in violation of the laws of thermodynamics.”
Heat flow is at zero when the plates are the same temperature, and that’s the entire point, Tim. The plate temperatures are not fixed. Heat flow tends towards zero over time, wherever possible. The plates all have identical physical properties, and view factors between them are reciprocal so there are no radiative losses past the edge of the plates. So, it’s possible. So, it happens.
All of your multiple misunderstandings that follow, Tim, all come from you assuming that there needs to be heat flow between the plates.
Yes, DREMT’s assumption of no heat flow between the plates is the basis of his misunderstanding all along.
It is clear that he does not understand the difference between thermal equilibrium conditions and steady state conditions. For an explanation of the difference, see
http://tll.mit.edu/help/equilibrium-vs-steady-state
and
https://en.m.wikipedia.org/wiki/Steady_state
As a result , DREMT assumes (and needs) Q = 0 between all the plates. Then most of his argumentation becomes essentially circular (i.e Tb = Tg means Q =0 means Tb =…. ) and as a consequence his energy balance equations don’t balance.
All this palaver because of this!
“…energy balance equations…”
You mean, “Eli’s math”.
“It is clear that he does not understand the difference between thermal equilibrium conditions and steady state conditions.”
So enlighten me. Why is it “steady state” and why does that mean a thermal gradient wants to establish itself of its own accord permanently, until the end of time, rather than heat simply flowing from hot to cold until the gradient has gone?
Because there is energy permanently coming in to the system !!!
If the energy input is switched off, and you wait long enough, then your statement makes sense
So your own private definition of “thermal equilibrium” applies only to a system without a heat source…i.e no system in existence. No wonder you’re so confused.
No I am using the conventional definition.
https://en.m.wikipedia.org/wiki/Thermal_equilibrium
There are some cases where you have thermal equilibrium at steady state conditions with energy input into the system.
For instance for our 2 identical plates, if both have the same energy input (i.e. 2 adjacent blue plates) then they will be both at the same temperature and be in thermal equilibrium.
This is in distinction to all the cases looked at here previously where only 1 plate has received the energy.
DREMT, I hope you now know understand the errors of your ways. If not I can knock up a few diagrams.
By the way for 3 plates, even if they are each receiving the same amount of energy, they are not in thermal equilibrium at steady state.
The middle plate is at a higher temperature than the two outer plates. This because the outer plates are only receiving radiation from the single central plate while the central one is receiving radiation from both outer plates.
You lost the argument here:

I think you must have made a mistake. Your link just takes us back 4 comments to the start of the thread.
I think you need to get some sleep as it is late where you are.
No mistake, creepy stalker.
No mistake! I was just letting you off the hook.

No mistake, creepy stalker.
DREMT when he cannot cope with a science based argument enters the 7 stages of grief below. None of them includes acceptance.

“Lets look at DREMTS greatest hits.”
Most of what Tim tries to represent as “REALITY” or my “multiple misunderstandings” is just his way of putting lipstick on a pig. Sorry Tim but that’s your position, and you’re stuck with it.
Tim, I have always recommended listening to the advice of experts.
This greasy pig’s only expertise is lipstick. He applies it extensively and inevitably smears it everywhere.
“They don’t just get warned”, should be “they don’t just get warmed”. Though someone should warn them that their properties are potentially lethal.
Well, that’s it from me. Have your last words…
…and I’ll be back in a couple of days to replace them with my last words.
As DREMT has left the building, albeit temporarily, I must wish him the best for the festive season. I hope he returns refreshed and ready to give us more of his valuable insights.
I won’t be commenting over Christmas, obviously. Try not to fall apart in my absence.
Despite the ordeal, I shall try to hold myself together.
Remember that absence makes the heart grow fonder. If you can manage to stay away indefinitely your absence will be much loved by all.
You want me to go away…got it. You could always just…stop responding to me.
Ok happy to do so. Presumably you will do likewise.
This could be the start of a great relationship.
I’m not the one who wants me to go away.
Clearly.
You love it, really. Mike, you’re a very creative person, and that’s a good thing. Your Wilhelm Reich comment made me chuckle.
Hope you have a good Christmas.
Likewise. Have a good Xmas.
DREMT. What happened to the Christmas truce? Don’t you like Silent Night and a friendly game of soccer?
Instead you keep climbing out of your trench and running towards the machine gun fire, while your colleagues are yelling at you to keep your head down. What a silly billy.
What happened, as usual, is that you are unable to stop talking to me.
It is admirable that you think you are willing to take a bullet for your friends. However if you look around,you might have noticed that they have deserted you.
I have engaged with you on that basis, that the amount of collateral damage you do to your colleagues is worth my time.
Huh?
Confused. What unusual state of affairs.
Well, it’s just first you said, apropos of nothing: “It is admirable that you think you are willing to take a bullet for your friends.”
Establishing that you thought I had some “friends” on here. However, further upthread it seemed like you might be gloating that some people you assumed were my “friends” had been banned. So it’s not clear who you think I am taking a bullet for (or in what way I’m “taking a bullet”). Then you made it stranger still with:
“However if you look around,you might have noticed that they have deserted you.”
1) If all my “friends” have been banned, how have they “deserted me”? 2) Nobody else has been commenting but me vs. the entirety of Team GPE throughout.
Then you really top it all off when you finish with:
“I have engaged with you on that basis, that the amount of collateral damage you do to your colleagues is worth my time.”
So it’s worth your time because you think my comments do “collateral damage” to people that have been banned and so aren’t around to confirm or deny any agreement with what I’m saying?
Mike…you need to find a better use of your time.
Yes DREMT, the assumption that you would have friends may have been incorrect. I grant you that. On that topic, I think the old cliche, “with friends like this, who needs enemies” might have be coined with you in mind.
Additionally I never explicitly suggested the banned ones were all friends of yours. It was clear that you didn’t have warm feelings for D.A. (maybe I’m wrong) and I somehow suspect he wasn’t enamoured of yourself.
I am not sure what your feelings were with respect to the others, other than you appeared to be channelling JD and his predecessor G*. If you are distancing yourself from their views on thermal physics, then progress has been made. Excruciatingly slow and painful for all, but progress is progress.
Even the enthusiasm of your sole supporter MikeF (aka Cynical) has waned recently leaving you totally you on your lonesome.
This reminds one of the classic joke. Surrounded by thousands of hostile Indians the Lone Ranger says to Toto, what are we going to do now?. Toto replies, what you mean “we” , Kemosabe?
Maybe Kemisabe, you can generate a posse of sock puppets to come to your rescue? Probably your only hope now that Toto has abandoned you.
Always full of Christmas cheer, aren’t you Mike?
Yes I thought you might enjoy it. Merry Xmas.
You won’t go quite as far as Des, and openly demand I commit suicide, but you keep pushing buttons and probing in certain areas that it appears you hope will cause harm (though you’re mistaken, I might add).
Such profoundly malevolent people. Not really sure why you harbour all this hatred of others who disagree with you, but, in the spirit of Christmas…I forgive you.
I can see that you are quite upset and for my part in that I apologise. I didn’t realise that you felt that way as you seemed to be more than happy to continue our exchanges indefinitely. Maybe you should think about discontinuing this tactic in the future. If you are worried that this might damage the reputation of the DREMT brand, this should be a secondary consideration to your overall happiness.
Alternatively, maybe you could, in a quiet moment over Christmas, contemplate whether your own behaviour has been exemplary. Simple things like restraining your tendency to annoy, antagonise and upset others with your gratuitous PSTs and related behaviour would result in your comments being treated much more respectfully by myself and I suspect others.
So let’s both try to forgive and forget and start afresh after the holiday season.
Have a merry Xmas.
Mike deliberately gets everything wrong.
It’s simple: you “people” are scum. Where in a normal human being there is a soul…in you there is just an infinite vacuum. You (collectively) are simply a relentless malevolent force. You have no humanity, no decency, no integrity. Nothing. You are simply the antithesis of everything that is human. I can’t even be angry at you. I can’t even conceive of an emotion that is appropriate. You’re just the abyss. That somebody like Dr Spencer would allow you creatures to operate here is nothing short of staggering. He needs to wake up to what you are, and what is going on.
Thank-you DREMT for your noble sentiments which are greatly appreciated at this time of the year. Who amongst us doesn’t appreciate being called scum. A very thoughtful touch and very Christian of you.
As a member of the collective “you” I am going to give you some gratuitous advice and the good news is that I am not going to charge you for it.
It was clear that it was all going to end up in tears for you, and that is why, in my case, you were periodically offered exit points, which regrettably you ignored and carried on regardless.
Unfortunately you came to the table lacking adequate skills in the appropriate areas in the first place. You ended up debating with people who clearly had scientific backgrounds and were numerate and it was unsurprising that you floundered so badly .
You also lacked rhetorical skills and I suspect ( correct me if I am wrong) that you regarded your gratuitous admonitions to “Please Stop Trolling” as your crowning achievement . I say this because you used it ad nauseum to label those who you disagree with, and it became your trademark.
This was combined with a manner that conveyed the utmost confidence that only you were totally right and the rest of us were just ignorant fools* . You made that quite clear on numerous occasions. You could never admit, heaven forbid, that you might be wrong. You ploughed on regardless, never admitting a scintilla of doubt. Not even a micro-scintilla. Perhaps , in the future, you could learn some humility and start with a femto-scintilla of doubt and work your way up.
DREMT I suspect that you may regard me as a sanctimonious old prick, but I have admitted to my mistakes here and moved on. I have even had a femto-scintilla of doubt about some of the material we have exchanged views about. However, within a femto-second, I realised I was not currently residing in one of the parallel universes in which the laws of physics have been repealed.
Finally for the sake of your mental health (and mine) my advice would be to comment at the Joe Postma site where your comments will be more warmly received and you will not be in danger of having another meltdown.
On that topic I suggest you download the Calm App and learn to meditate. I am a great believer in mindfulness as it can soothe a troubled mind.
Once again have a great Xmas and New Year.
* This also was an unfortunate characteristic of your predecessors who are no longer with us, and made some surmise that you were the latest reincarnation of these miscreants.
Insulation keeps things warmer. It doesn’t make things warmer. Insulation does not heat anything.
No tears from me, scum.
DREMT, Glad you appear to have calmed down. Was it the spirit of Yuletide or the Calm App that did the trick?
However, you do appear to a have a serious anger management problem.
I think it needs to be attended to urgently for your sake and for everybody here who is getting verbally abused.
DBT is a modality that has been proven to be successful for the treatment of emotional dysregulation. I hope you can locate a suitable program in your area and complete a course. Otherwise we may find that you are likely to get even more out of control.
In the meantime practice some mindfulness. Concentrate on your breathing and try to be in the present and not think about thoughts that might distress you.
Good luck on your journey.
After much help, DREMT now understands/supports the analogy Earth’s atm. GHE acts as insulation:
GHE keeps things warmer. GHE doesnt make things warmer. GHE does not heat anything.
My expectations are DREMT/Joe’s short term brilliance will fade away in the near future in a fit of anger (an anagram for a dear departed).
Inhuman, even over the festive period. Oh well.
Oh the inhumanity!

Yeah. A field test of his theory. The peer review will definitely need to be paywalled.
Not sure if this discussion is the place to say it .. so I’m sitting on the AGW fence, having read and tried to make sense of arguments on both sides, which is hard amongst all the emotional rhetoric and propaganda. One thing though, harping on about consensus really turns me off. Real science has or should have nothing to do with consensus. If it did, we’d probably all still be living on a flat earth or blood letting as a cure all. In any case rather than trying to use FUD to bludgeon the world into stopping burning fossil fuels, which is never going to happen, our best bet is to replace them with something far far better, by making nuclear fusion generation a reality within the next 50 years. It can be done if the investment is big enough; then we win, irrespective of the truth of cataclysmic AGW. Particularly as the energy would then be available to, if necessary, make and run machines to modify the atmosphere (sequestrate CO2, or whatever), as well as creating other capabilities that we can hardly yet even imagine.
Ron, Wellington, NZ.
Kiwironnie, Have you spoken with anyone from Sidney lately?
https://www.nytimes.com/2019/12/18/world/australia/record-heat.html
Mr S. There are climate anomalies all the time, some hot, some cold. Those aren’t of themselves hard evidence of either catastrophic AGW or an impending ice age. To me the whole AGW argument boils down to the degree of climate sensitivity to very small changes in atmospheric gas concentrations. That jury is still out, although now unfortunately a more biased jury you would be hard pressed to find.
Things are getting worse here.
A state of emergency has been declared in NSW.
https://www.abc.net.au/news/2019-12-19/nsw-bushfires-sydney-smoke-and-heat-live-blog/11812822
Meanwhile our glorious leader ScoMo has responded to the emergency and fled the scene for a cooler environment (Hawaii).
It is understandable as ScoMo needs to clear his lungs for the political battles ahead, and his ability to withstand the heat of the kitchen is limited.
Understand that consensus is born out of the abundance and consilience of evidence. It is the manifestation of science. In other words, science does not occur as a result of consensus, rather consensus occurs as a result of science. And it evolves as new information is added to the collective wisdom of science as it should. So in this respect I’m having a hard time understanding why you would be turned off by this. Can you clarify why this is offensive to you?

I see Swanson ran away again, so I guess he got the point.
DRsEMT, No, I just got tired of your complete inability to understand that in both the 2 plate and your 3 plate models, there’s 400 watts being supplied to the Blue plate from an external source. Whether that 400 watts if from sunlight or something like a resistance heater doesn’t matter.
Swanson, in the 3-plate scenario, the blue plate is the heat source. Whether you imagine the 400 W is generated internally, comes from an “external source” (never specified and it’s never bothered you before) or whether there is a heater inside (irrelevant since the plates are perfect conductors), it doesn’t matter. You are simply in denial. You know that the idea of passive plates making the heat source plate hotter is stupid, so you try to find ways to evade it.
I’m afraid that is exactly what you’re arguing…and, deep down, you know it. You just can’t admit that you’re wrong.
DRsEMT insists that there is some unspecified difference between providing 400 watts to the Blue plate in the 2 plate case and the 3 plate case. Since DRsEMT presented the 3 plate model, it’s DRsEMT’s responsibility to specify that source, not mine. The distinction never entered the “debate” before, since DRsEMT never raised it.
DRsEMT then re-states his bogus physics when there is abundant factual evidence that DRsEMT’s conclusions are in error.
More denial from Swanson.
Again:
“…in the 3-plate scenario, the blue plate is the heat source. Whether you imagine the 400 W is generated internally, comes from an “external source” (never specified and it’s never bothered you before) or whether there is a heater inside (irrelevant since the plates are perfect conductors), it doesn’t matter.”
DRsEMT continues to deny that a radiation shield will increase the temperature of a heated body, whether the source is an external energy source, as shown in DRsEMT’s diagrams, or an internal energy source, for which where would be no arrows in a diagram.
My previously stated temperature for the Blue plate with 2 Green plates with e = 1.0 was ~345 K, which is what other folks arrived at.
I’m glad you finally agree that in the 2-plate scenario the heat source is the sun, and in the 3-plate set-up the heat source is the blue plate.
Some people would have started to think things through by now, pondering such important points as, “well, one way to look at it would be that in the 3-plate scenario, it’s kind of like (relative to the 2-plate setup) that you have a “sun” plate and two blue plates”…and they would be able to think, independently, about where such thoughts lead. Like a thought experiment. Where you think things through, for yourself. Maybe you could try that, Swanson?
“My previously stated temperature for the Blue plate with 2 Green plates with e = 1.0 was ~345 K, which is what other folks arrived at.”
Oh dear…another really cringey moment for Team GPE.
DREMT seem to have the strange hypothesis that surroundings can affect the Blue Plate, but not if we call the surroundings “Green Plates”.
I doubt this will help DREMT, but it might help others. It is a different way to arrive at the same answer.
For this scenario, start with an unheated blue plate and 2 unheated green plates at 0 K in 0 K surroundings (the three plate model for simplicity). Attach heaters to the *green* plates and warm them to 244 K. You could crank the power way up initially (say 10,000 W/m^2) for the green-plate-heaters, but turn the power down as the temperature reaches 244 K. The blue plate will also warm to 244 K due to radiation from the two green plates on either side. It will take 200 W/m^2 for each of the two green plates to hold the system at 244 K throughout.
Now turn on the blue-plate-heater to a fixed 400 W/m^2 setting — it will start to warm above 244 K (right, DREMT?). As you do this adjust the power for the green-plate-heaters to hold them at 244 K — you will have to turn them down from 200 W/m^2 since they are now receiving some radiation from the warmer blue plate. The blue plate will warm and eventually stabilize at some temperature above 244 K, with the green plates still at 244 K.
QUESTION: When the system stabilizes, how much power is needed from the green-plate-heaters to hold the green plates at 244 K, and what is the temperature of the blue plate?
The answers are, of course, 0 W/m^2 for the green-plate-heaters and 290 K for the blue plate. The green plates don’t require any external heating/cooling to stay at 244 K. The 200 W/m^2 they each receive from the blue plate by radiation is sufficient and replaces the 200 W/m^2 they originally received from their green-plate-heaters.
The now-passive green plates (the “surroundings” for the blue plate) will continue to be 244 K and the blue plate will continue to be at 290 K.
E. Swanson, DREMT/Joe cannot possibly agree with, or do an experiment showing, that a radiation shield will certainly increase the temperature of a heated body as that conflicts with DREMT/Joe’s long held incorrect view of how Earth’s atm. works ignoring the natural GHE.
Tim tries more false accusations, misrepresentations, distractions, deception and general trickery.
DREMT tries desperately to deflect from simple science. What — specifically — do you think is incorrect, DREMT? No general complaints.
No matter how we get to the solution, it is the same.
* The blue plate receives 400 W/m^2 from some external source.
* The warm blue plate transmits 200 W/m^2 to each of the cooler green plates.
* The cool green plates transmit 200 W/m^2 each to the even cooler fixed 0 K surroundings of space.
There is one and only one solution (given the standard idealized conditions).
* The blue plate must be 290 K.
* The green plates must be 244 K.
“The blue plate receives 400 W/m^2 from some external source.”
The blue plate receives 400 W, either internally generated or externally generated, depending on how you want to look at the problem. We have been assuming a surface area of the blue plate of 1m^2 each side, for simplicity. Thus 400 W input translates to an output of 200 W/m^2. 400 W/m^2 input is incorrect, Tim. Regardless, the blue plate is the heat source, in the 3-plate scenario, as it seemed Swanson was finally able to accept.
And again, regardless of all your nonsense, the passive green plates will equilibrate with the heat source at 244 K, each emitting 200 W/m^2. Reciprocal view factors mean no radiative losses past the edge of the plate, so there is no reason for the green plates to be less than 244 K. An idealized problem with a simple solution.
Now, if you don’t mind, I’m going to go back to waiting for a response from Swanson, which is what I was doing before I was so rudely interrupted. At the very least, he needs to acknowledge his boo-boo over the 345 K.
You are dismissed, Tim.
We agree the green plates must be 244 K. That is a good start.
But then “the passive green plates will equilibrate with the heat source at 244 K, each emitting 200 W/m^2.”
You are claiming that 200 W/m^2 will flow naturally from one object at 244 K to a second object at 244 K. This goes against both intuition and thermodynamics. Heat ONLY naturally goes from warm to cool.
Also, you seem to put great importance on the word “passive” — why? 244 K is 244 K, no matter how the object got to to 244 K. What if the we had “active” plates held at 244 K. Would the blue plate then be warmer than 244 K?
(You call these “diversions” — I call it probing your understanding. If you can’t answer closely related questions, then you really don’t understand.)
Tim, I’m not sure what your problem is, but you really are quite rude.
I was having a conversation with Swanson, in which he got himself into a bit of a pickle, and I was waiting to hear what he had to say. Now you have barged in, demanding answers to questions, and claiming that a failure to answer will show a lack of understanding. You make all sorts of assertions about what you think I’m saying, and apparently ignore all previous explanations.
Not good form, Tim. Not good form.
I’m waiting to hear from Swanson. If you want answers to questions, perhaps scroll up and read through the preceding 600-odd comments, including links to previous lengthy discussions (not to mention the 900-odd comment discussion about the Steel Greenhouse which occurred 6 years ago now, and which covers much the same ground as the Green Plate Effect:https://climateofsophistry.com/2013/03/08/the-fraud-of-the-aghe-part-11-quantum-mechanics-the-sheer-stupidity-of-ghe-science-on-wuwt/). Have a catch up, sort yourself out, and then take a back seat while we wait to hear from Eric.
You are dismissed.
DRsEMT, Yes, looking back thru many posts, my 345 K result was for the 3 plate case with e = 0.5 on the Green plates, not for e = 1.
That post from Joe is rather long and full of references to Planck, cavity radiation and quantum physics, etc. Sounds rather like your stuff, with his usual disdain for those with supposedly less brain power than he. No, I’m not going to read thru all 900 comments. However, I think he doesn’t get it that the steel “greenhouse”, (aka: radiation shield) isn’t a cavity, since the energy isn’t trapped within, but flows from some source (internal in his case) out to deep space at 0 K.
BTW, that you bring this up suggests that you are actually Joe.
I read Willis’s “Steel Greenhouse” years ago, and Willis was correct then, just like the “Blue Plate” experiment is correct now. Joe’s discussion was wrong then, just like yours is wrong now. Those multiple comments over multiple years have discussed it all, so there is little point in rehashing it all.
I will point out one key error Joe made in the link you provided.
“If in this condition half the energy gets radiated inward, then he could have said it would combine with the interior output and thus increase the temperature of the interior output, i.e., 1+0.5 = 1.5. Wow, addition! Of course, for these people who don’t know about addition and who don’t know about cause and effect and logic, they might just stop the process there. But Willis can’t do that because he’s either too stupid, or because he knows that explaining it this way would expose how arbitrary it is to stop this process after a single go-around. Because of course, if the output is now 1.5, then half of that will now have to be returned from the shell because this is now what the shell is receiving. This is a geometric sequence that goes as 1.5 to the power n (1.5n) where ‘n’ is the number of cycles. “
No. He is correct up to here: “if the output is now 1.5, then half of that will now have to be returned ” — which would be 0.75 returned. Combine this with Joe’s correct logic “he could have said it would combine with the interior output and thus increase the temperature of the interior output, i.e., 1+0.5 = 1.5”. This means that Willis ‘could have now said the 0.75 would combine with the interior output and thus increase the temperature of the interior output, i.e., 1+0.75 = 1.75.’ Wow — Joe had the right idea (just bad execution). The next iteration would be 1+(1.75/2) = 1.875. Then 1+(1.875/2) = 1.9375. Then 1.96875. Then 1.984375. Then 1.9921875. The output from the shell approaches 2. The output does NOT approach 1.5^n.
I must tread carefully.
DREMT is unlike his normal self and very touchy at the moment about people suddenly intruding into his conversations.
In this regard, he is, of course, a paragon of virtue and would never do such a thing.
He would never ever just thoughtlessly drop a PST into other people’s exchanges. He wouldn’t ever dream of indulging in this kind of behaviour. Would he? God forbid.
“Those multiple comments over multiple years have discussed it all, so there is little point in rehashing it all.
I will point out one key error Joe made in the link you provided.”
I won’t rehash it but I will rehash it, he says! All of this is just a rehash, Tim. I would encourage people to read through the article and the comments fully, rather than taking snippets out of full context or putting words into other people’s mouths. Just have a read through, think about what’s been said, relate the 3-plate scenario to the sphere and the shell, and just think clearly about it.
Anyway, it seems Swanson is finally back, the person I was actually talking to.
“No, I’m not going to read thru all 900 comments. However, I think he doesn’t get it that the steel “greenhouse”, (aka: radiation shield) isn’t a cavity…”
He’s not saying it’s a cavity. He is of course continually making the point that you are, that the energy from the other side of the shell is always radiating out to space. He occasionally talks about what would happen if the energy were trapped, that’s all. So he does sometimes refer to it as a cavity, in the correct context. You would find out a lot more about what’s actually been discussed if you could just be bothered to read through the comments…
…onto your beloved “radiation shields”. You guys sure do love your ambiguous terms.
Here’s the wiki link to “radiation shielding”:
https://en.m.wikipedia.org/wiki/Radiation_protection#Radiation_shielding
Not at all what you’re trying to describe, is it? And we have already been through “radiant barriers” and “heat shields” before. Neither of them do what you need them to! We discussed heat shields further upthread, radiant barriers were discussed another time. I suppose I can link back to those discussions, if necessary.
That is not a “snippet out of context” DREMT. That is the core of Postma’s argument, in his own words.
This is typical of what Postma writes. He says several things that are correct. It suckers people in. Then he makes some major error that *sounds* plausible enough. Most people either don’t care or don’t understand enough to catch the error.
After making a few simplifying assumptions, Postma correctly notes that 1/2 the energy gets fed back. The first iteration is indeed 1+0.5= 1.5. Surely if he got THIS much correct, then the rest must be correct too. But no.
The sequence is not
1 + 0.5 = 1.5
1.5 + 0.75= 2.25
2.25 + 1.125 = 3.375
…
This would require the base input (the first number in each row) to increase each iteration. In “blue plate language”, this would be like saying the blue-plate-heater starts at 400, then increase to 400*1.5=600 a little later, then to 400*(1.5^2)=850 as more and more radiation comes back from the green plate.
The correct sequence is
1+0.5 = 1.5
1+.75 = 1.75
…
In “blue plate language”, the blue plate initially radiates 400 and half = 200 comes back, so now the blue plate radiates 400 + 200 = 600. Half = 600/2 = 300 comes back, so the blue plate must now radiate 400+300 = 700. Half = 350 comes back ….
Postma’s strawman, based on incorrect application of his own logic, diverges to infinity. The correct answer, based on correct application of Postma’s logic, converges quickly to the blue plate radiating exactly twice the power supplied but the blue-plate-heater.
“…the core of Postma’s argument, in his own words.“
Don’t be ridiculous, Tim. Just let people read through it all, and decide for themselves. Why do you find that so difficult? Why are you still interjecting!?
DRsEMT plays the old semantic game again. We weren’t discussing nuclear radiation, but thermal IR EM radiation and shielding such emissions. DRsEMT assumes that his pronouncements debunk many decades of work in heat transfer engineering, yet radiant shielding is widely known to work and is included in text books as well. My Green Plate demo is just another example of same.
“We weren’t discussing nuclear radiation, but thermal IR EM radiation and shielding such emissions.”
My point exactly. You play these semantic games of introducing ambiguous terms, and then refusing to specify what you mean. A “radiation shield”, if you look it up, are actually those shields that protect against gamma rays, etc. Clearly irrelevant. So perhaps you really mean, “radiant barrier”. Those have been discussed before. They don’t do what you need them to. So perhaps you really mean, “heat shield”. Those have been discussed before. They don’t do what you need them to. In the end, it’s not up to me to make it clear what you are referring to.
Tim, on the other hand, plays different games with the Steel Greenhouse link. Postma goes through various ways of interpreting Willis Eschenbach’s original illogic, in the head post, but also in the comments (particularly in some of the initial exchanges, with Tallbloke). Whether or not any initial interpretations were “straw men” is irrelevant, since Postma correctly rejects any and all subsequent interpretations of it, that result in the shell warming the sphere! What Tim wants is for anybody reading not to take the time to read through the article and comments. Particularly anything relating to the correct answer to the problem, and the obvious parallels to the correct answer to the 3-plate scenario. The sphere heats the shell, until it’s the same temperature as the sphere…
DRsEMT, Your “red herring” ignores the fact that “radiation shield” also refers to thermal radiation and ignores the context of these many preceding posts about thermal radiation. See: Siegel and Howell, “Thermal Radiation Heat Transfer”. I have their 4th Edition (2002), where Radiation Shields are specifically discussed on pages 299-302. Note that the textbook began as a NASA report many years ago and is still being used in engineering classes.
Here’s other examples:
https://cryogenicsociety.org/resources/defining_cryogenics/thermal_radiation_shields/

https://www.sciencedirect.com/science/article/pii/S0306261912000785
What “red herring”?
“since Postma correctly rejects any and all subsequent interpretations”
… and yet no other scientist in the world agrees with him. No journal publishes his work.
No, Postma knows just enough to be dangerous. His errors are easy to spot and have been repeatedly pointed out.
Tim, the more you go on, the more people will want to check out the link. And, unlike the links that Team GPE provide, mine actually support my argument.
By inspection, DREMT/Joe’s link at 6:52am only in part supports his argument as it discusses particle shields & high energy gamma and X-ray radiation while LW and SW (with some UV) generate this atm. blog’s arguments.
DREMT/Joe’s link at 8:45pm is in part just as incorrect as his arguments on this blog so in that sense supports his many times incorrect arguments since they are not experimentally supported thus are easily dismissed by many on this blog.
E. Swanson’s links 1:13pm do support his experimentally determined comments and have become generally accepted on this blog and elsewhere.
“By inspection, DREMT/Joe’s link at 6:52am only in part supports his argument as it discusses particle shields & high energy gamma and X-ray radiation while LW and SW (with some UV) generate this atm. blog’s arguments.”
Deliberately missing the point I was making.
“DREMT/Joe’s link at 8:45pm is in part just as incorrect as his arguments on this blog so in that sense supports his many times incorrect arguments since they are not experimentally supported thus are easily dismissed by many on this blog.”
What started the whole discussion, this time, Ball4? Oh yes…Hughes experiment.
“E. Swanson’s links 1:13pm do support his experimentally determined comments and have become generally accepted on this blog and elsewhere.”
They don’t support it. Nowhere do his links support the idea of blackbody plates making the heat source hotter. The only textbook examples that have ever been brought up previously in order to try to support these crazy ideas involve plates held at fixed temperatures.
“Oh yes…Hughes experiment.”
Ha, that’s the improper experiment generally laughed off as bungled, you can find many of these on the ‘net. E. Swanson’s proper experiment on the other hand is easy to replicate & not bungled.
“Nowhere do his links support the idea of blackbody plates making the heat source hotter.”
All of E. Swanson’s links and experiments support the idea of added real plates making the heat source hotter when steady state temperature equilibrium is achieved since that is what proper experiments demonstrate consistent with text book 1LOT and 2LOT. Universe entropy MUST increase in a real process thus this is easy to show in theory and proper experiment.
Try doing some real proper experiments DREMT/Joe taking actual replicable data since you could learn a lot and become embarrassed at some DREMT/Joe past comments.
“Ha, that’s the improper experiment generally laughed off as bungled…”
Team GPE does indeed just try to laugh it off. Shamelessly.
“All of E. Swanson’s links and experiments support the idea of added real plates making the heat source hotter…”

“No DREMT. That takes more fuel. Added insulation to your home economizes on fuel.”
DRsEMT-Joe wrote (referring to my previous post’s references):
My post was intended to show that the term “radiation shield” which I used is common in the field of engineering called thermal radiation heat transfer. I doubt that DRsEMT-Joe has taken the time to read the text book(s) and the example given is a well proven use of multi-layer insulation to reduce the energy loss from some body, be it something located in the vacuum of space or a device for cryogenic applications on Earth.
It should be obvious to a deep thinker like Joe-the-Post-Man that in a situation where such insulation is added to a body with a constant input of energy, the result would be that the temperature of the body would increase. And, it works with a single layer as well.
DREMT/Joe your 9:25am defense of what you call the GPE Team is duly noted. Keep it up, there is no shame defending 1LOT and 2LOT with experiments, you have come over from the dark side at 9:25am. Maybe, but I doubt, in some future comment DREMT/Joe will prove his defense of the GPE Team (DREMT term) worthy with a proper experiment and replicable data.
“My post was intended to show that the term “radiation shield” which I used is common in the field of engineering called thermal radiation heat transfer.”
Ah, but do you actually mean “radiation shield” (protection from gamma rays, etc), “heat shield”, or “radiant barrier”? Please let me know which of the three you mean.
“It should be obvious to a deep thinker like Joe-the-Post-Man that in a situation where such insulation…”
Uh oh! I showed you what Ball4 has to say on the subject of insulation and heat sources in my 9:35am comment.
I guess it’s now Ball4 vs. Swanson…
DREMT guesses wrong, he should do proper experiments eliminate guessing.

The smokey haze in this photo reminds me of the summers 2017, 2018 where I live (Oregon). It was awful.
https://images.scribblelive.com/2019/12/19/d3458ca6-26c8-4df8-8c58-d7aea2c2f97f.jpg
This is the situation in a large part of NSW (minus the Harbour Bridge). The forecast for the next few days of hazy with a chance of embers seems to be the situation here.
Lol!
Well, the two summers I mentioned included forecasts of potentially record breaking heat. The models didnt account for the smoke, though, and each day ended up about 5 F. less than expected. Small consolation.
Huffy
While you and Joe struggle to get the hang of back-radiation, maybe back-convection (my wording) would be easier to understand?
The temperature difference between forward and backward moving air is the net, and determines the rate of convective heat transfer. Obviously.
Sounds familiar, right?
☺️
Still confused? Color me surprised!
When air Is warmed and starts to move away from a heated surface, it is at the same time replaced by cooler air. The phrase [nature abhors a vacuum] comes to mind.
So, what determines the rate of heat transfer?
The difference in temperature between the former and latter.
Whatever you say, Snape.
Dont take it on faith, Huff, put it to the test:
A) Heat a pot of water to 120 F, then place it on your kitchen counter. After 60 seconds, check the temperature.
B) Again, heat a pot of water to 120 F, but this time place it in your fridge for 60 seconds. Check the temperature.
C) Lo and behold, you will find the pot in the fridge has cooled faster!
D) Share your discovery with Joe Postma.
******
* If necessary, a similar experiment could be constructed, where the pot of water remains on the stove throughout (constant heat source).
OK, Snape.
Glad to help.
I’m glad you believed you had a point.
Huffy,
If a 120 F surface [reflected away] the energy carried by incoming air that is less than 120 F, then It would make no difference whether the pot of water was placed on the counter or in the fridge. Rate of cooling would be the same either way.
OK, Snape.
I agree with you
What’s up to every one, it’s really a nice for me to go to see this
web page, it consists of useful Information.
Hi there, I read your blogs regularly. Your story-telling style is witty, keep it up!
