UAH Global Temperature Update for April 2020: +0.38 deg. C

May 1st, 2020 by Roy W. Spencer, Ph. D.

UPDATE: Changed emphasis from Northern Hemisphere extratropics to entire Northern Hemisphere (h/t John Christy)

In April, 2020, the Northern Hemisphere experienced its 2nd largest 2-month drop in temperature in the 497-month satellite record.

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for April, 2020 was +0.38 deg. C, down from the March, 2020 value of +0.48 deg. C.

The Northern Hemisphere temperature anomaly fell from +0.96 deg. C to 0.43 deg. C from February to April, a 0.53 deg. C drop which is the 2nd largest 2-month drop in the 497-month satellite record. The largest 2-month drop was -0.69 deg. C from December 1987 to February 1988.

The linear warming trend since January, 1979 has now increased to +0.14 C/decade (but remains statistically unchanged at +0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).

Various regional LT departures from the 30-year (1981-2010) average for the last 16 months are:

    It appears the arctic air was released last month, mixing well with the tropics. This indicates an increase in meridional jet stream flow in the northern hemisphere. Confirmed by the negative departure in the USA 48 region. Looking forward to the details / data.

        If you want more ask him how “Jupiter and Saturn cause the sun to move away”.

        • Scott R says:

          Svante,

          The sun must move relative to Jupiter and Saturn. You toy with me for no apparent reason as this is a known fact that this is happening. Here is a cool place where you can see that for yourself.

          http://www.orbitsimulator.com/gravity/articles/ssbarycenter.html

          • Svante says:

            Earth is twelve times faster than Jupiter around the Sun,
            and thirty times faster than Saturn.
            So the distance difference is averaged out over the year.

          • Scott R says:

            Svante,

            I understand what you are saying… what you have missed is the significance of the polar night, and the albedo of the north pole verses the south. The south is much better at reflecting energy back into space. When you position Jupiter and Saturn so that a LITTLE bit of extra energy goes to the south pole instead of the north pole, it is enough to tip the earth from one equilibrium energy state into another. It starts off as tiny energy losses each year, but once the cycle gets going it snow balls. More snow in the arctic causes more snow and ice in the arctic and so on. Where the lower equilibrium point is reached will depend on many factors including to a small degree man made influences.

          • Svante says:

            And yet Earth orbits the Sun-Earth barycenter.

            With Jupiter at 5.2 AU and Earth at 1 AU, Jupiter pulls the
            Sun-Earth pair in the same general direction.

            Even more true for Saturn at 9.6 AU.

            I agree that the climate is sensitive due to feed backs.

          • Scott R says:

            Svante,

            The sun moves very little due to the earth. Jupiter, Saturn, Uranus, and Neptune all move it more. Actually, Jupiter moves it more than the earth by more than 3 orders of magnitude. Anyways, the earth works WITH Jupiter and Saturn to move the sun away. The sun must move away to balance the planets when they are all bunched on 1 side… otherwise the orbits would not be stable. Take a look at where all the planets will be late June and please think about it. I do not think it works how you are thinking where the earth is tethered to the sun somehow. I do not believe gravity works that way. Everything is in a constant free fall towards the sun, and the orbit of Jupiter and Saturn change the shape of every other orbit.

          • Svante says:

            Scott R says:
            “I do not believe gravity works that way.”

            Jupiter makes the Sun wobble compared to the background stars,
            but Earth wobbles with it so it has little influence on the Sun-Earth pair.

            Jupiters effect on Earth is in delta distance between the two. Ephemeris calculations show that the effect is small.

            “I do not believe gravity works that way.”

          • bdgwx says:

            It’s the same thing with the Earth-Moon wobble. The Earth-Moon system causes the Earth to wobble around the barycenter. But the positioning of satellites, space shuttle, space station, etc. do not bob in and out because of that wobble. There is no difference in the amount of Earth-shine our satellites receive due to this wobble.

          • Scott R says:

            Svante,

            I agree with you that the Jupiter / Earth direct gravity interaction is small. Let’s forget about all the other planets for a moment and focus on Jupiter, sun and earth. Let’s say everything else went away for the purposes of this discussion and say that Jupiter’s orbit is a perfect circle. When you do that, you have a simple barycenter movement with Jupiter and the sun, where the sun will always move away from Jupiter is it completes it’s orbit. So you are telling me this 1 motion makes no difference to the earth sun distance. Then on top of that Jupiter’s movement between perihelion and aphelion makes no difference, and Saturn makes no difference. etc etc etc I can’t believe it, sorry.

            If you want to prove it to me, start with the simple example I gave you with Jupiter with a perfectly circular orbit and explain how that would work.

            Because it doesnt make sense from the physics POV.

            You would be right if Earth rotated around the Sun-Jupiter barycenter. It does not, it rotates around the Sun-Earth barycenter. Your idea would have merit if Earth rotated around both Jupiter and the Sun.

            Contrary to your school book, the orbits of Jupiter and Earth are not concentric.

            Earth’s aphelion/perihelion is +/- 0.02 AU due to eccentricity. The residual is 0.0000 AU.

          • Scott R says:

            bdgwx I think we all agree that the Milankovitch cycles cause the orbit of the earth to change. IF it was true that Jupiter had no effect on the earth’s orbit similar to the moon / earth / satellite example you gave, why would the earth’s orbit ever change? We also know that satellites do not stay in orbit forever by the way. In fact, our climate data must be adjusted for that. The Milankovitch cycle is caused by the sum of small perturbations over a long period of time. Like it or not, these small perturbations are making a difference to the temperatures of the oceans. It isn’t a steady march in one direction. There are cycles smaller than 100,000 years related to the earths eccentricity. Can you help me get to the bottom of this? I understand that the amplitude of the change in earth / sun distance is small.

            —————————–

            Right bdgwx! All it does is lift the oceans several feet. Think of what it does to the atmosphere. Of course the moon has no effect on climate because it goes around monthly.

            The ignorant always points instantly to earth-shine because they know it isn’t a great deal and they pretend like they can’t think of anything else that might be influenced by such powerful forces. Or perhaps they are just too stupid to think period.

            Just a 1% difference in clouds, smaller than we can even measure would have sufficient effect to change climate we have observed. But that simply isn’t a politically correct thought, slap my hand as punishment.

            And of course we know the sun has cycles roughly in time with Jupiter’s orbit. But thats not a politically correct thought either is it bdwgx?

            In my view we have a lot to learn about radiant heat and the frequencies in which it is emitted. Does relatively low frequency light actually warm something with a higher frequency? We understand wattage of various frequencies but is this only potential to heat or is it actually usable watts?

            Frequency of sound is simply canceled from opposing frequencies and forms the basis of noise cancelling headsets and is a sound engineers challenge of wiring and placing speakers.

            If you shine some low frequency light back at the surface you may cancel out low frequency light emitting from the surface and in compensation the source of the low frequency light shines an equal amount toward space. At that point it was required to completely invent a new effect – a gaseous insulating blanket.

            I am not saying it doesn’t work. In fact I am pretty sure it works for at least one layer. I am merely saying science has a ways to go. I am all ears on what I might have missed already.

          • bdgwx says:

            bill,

            The ocean is not in free orbit around the Earth. It is affected by the tidal influence of Moon in a different way. It has nothing to do with the Earth-Sun distance or the Earth-satellite distance.

            Regarding my Earth-shine comment…the Sun-shine that the Sun’s satellites receive is not affected by the Sun-Jupiter barycenter wobble just as the Earth-shine that the Earth’s satellites receive is not affected by the Earth-Moon barycenter wobble.

            Clouds are a topic of ongoing and intense research in the scientific community. Their radiative forcing effect is considered. They are not ignored in any way political or otherwise. This has nothing to do with the Earth-Sun distance though.

            Solar cycles are a topic of ongoing and intense research in the scientific community. Their radiative forcing effect is considered. They are not ignored in any way political or otherwise. Again…this has nothing to do with the Earth-;sun distance though.

            And yes solar cycles are believed to be influenced by planetary orbits. Again…this has nothing to do with the Earth-Sun distance though.

            Yes. We are still learning about the warming effects of radiation. Our knowledge on the topic is not perfect nor will it ever be. But it’s also not zero either and the level of knowledge is always increasing. Again…this has nothing to do with the Earth-Sun distance though.

          • Scott R says:

            bdgwx,

            Thanks for the link to that discussion. A very fascinating (at least to me) argument there. Perhaps we are all wrong and live in an electric universe which explains why the earth bonds to the sun’s barycenter movement and Jupiter does not. (haha?) I wonder if they discussed dark matter at all and the orbit of stars around the galactic center. I’ll have to keep reading / learning. That is what this is all about.

          • bdgwx says:

            Scott,

            Yes. We can definitely agree on Milankovitch cycles. However these cycles do not change the amount of radiation Earth receives. Instead they change the distribution of that radiation.

            Yes. We can definitely agree that Jupiter perturbs Earth’s orbit. However, these perturbation has have no residual effect on the amount radiation Earth receives when examined over several orbital periods.

            What I and experts disagree with Zharkova over is the claim that the Sun-Jupiter barycenter wobble affects the amount of radiation Earth receives. It has no affect because the Earth-Sun distance does not change because of solar inertial movement.

          • Scott R says:

            bdgwx,

            The distribution of energy does impact our climate because the albedo is not constant. The south pole reflects better than the north pole. I think we agree that if the south pole is getting more energy on the millennial time scale, the earth cools.

            Proposal: small perturbations in the earths orbit sum up to create the Milankovitch cycles. The perturbations do not act constantly at the same vector and will be cyclical, proportionate to the location of Jupiter primarily. Agree?

            The short term perturbations in the earths orbit do not change the total TSI, but it does change where the energy is received, therefore impacting our climate.

            Thats just false bdgwx. You can try to argue that the effect is too small but you are ignorant if you argue it doesn’t exist. And its an ignorant argument its too small also because you have no data to support that beyond direct total sunlight.

            It may have little to do with earth sun distance but it does have something to do with it. You can’t ignore that science believes that two orbiting bodies assume similar shaped orbits around their common barycenter. Add in more planets and the laws of physics on gravity and distance and there it would be violation of the laws of physics for it to not have an effect on earth sun distance.

            Ontop of which earth sun distance is but one of many variables. . . .including affects of gravitational forces on solar gases potentially affecting solar cycles and the frequency of light given off by the sun. then a total wild card of magnetic pulses occurring between the earth and sun from unknown causes. Magnetism pulls on everything to some extent. but you ignorantly just believe what you have been told to believe. Nobody has proven it to you are you would be laying out proofs rather than ignorantly pooh poohing everything you don’t want to believe.

            And science is making slow progress on the affects of other planets in climate. Here is an article from PNAS on just that topic. https://www.pnas.org/content/115/24/6153

            bdgwx picked up on that Nate. Perhaps you should do a little research on how vibrations warm stuff. Thermosphere is very hot because it warms from high frequency light from the sun and has nothing around like CO2 to cool it before it gets that hot.

            Add any two identical wave frequencies together in opposite phase and get get less amplitude. Study up on noise canceling technology.

            bill,

            I never said ocean tides are not influenced by gravity. What I said was that ocean tides do not behave the same way as objects in free orbit. The fact that ocean tides ebb and flow does not in anyway suggest that satellites in free orbit bob in and out.

            The Earth-Sun distance does NOT change as a result of solar inertial movement about the Sun-Jupiter barycenter. Therefore the amount of radiation received by Earth via this same phenomenon does not change either. It’s not the effect is small; it’s that the effect is completely non-existent. If you are trying to argue otherwise then understand that the argument is wrong.

            Regarding clouds…refer to IPCC AR5 WGI chapter 8. There you will find information about clouds, their effect on the climate system, estimates of the effect, and numerous publication citations in which you can explorer all of the details if you desire.

            bdgwx it would be a violation of basic well accepted physics of gravity and distance if the satellites didn’t bob in and out when exposed to gravitational fields from the other planets.

            The only rational argument you can make is the bobbing is extremely minor. But it does exist. However, its silly talking about the planets themselves having solar TSI affected by the process as the movement is very small because the gravity difference and distance compared to the sun’s gravitational pull is very small.

            However, the speculation on this having a climate effect isn’t based upon planets slightly changing their orbit as they move around the sun in front of say Jupiter and then on the other side of the sun from Jupiter. The theories I have discussed are what effects Jupiter in particular and Saturn secondarily have on solar gases. It takes very little force to move gases. Solar scientists haven’t found convincing evidence of this but OTOH they are struggling to come up with anything convincing about how the sun actually operates and varies essentially blowing prediction after prediction and getting stuff right essentially by random chance.

            I am not interested in exploring cloud effects. I am interested in how clouds vary. For a starter it would be good if we could measure clouds to somewhere above 99% accuracy. Then you would at least know what to look for.

            bdgwx,

            The earth’s albedo is not uniform, therefore the shape of the orbit does change the amount of energy the earth absorbs. The south pole is especially good at reflecting the suns energy. Currently, the alignment of Jupiter and Saturn in the current location is causing the perihelion to be reduced slightly, and the aphelion to be increased slightly. That puts more energy on the south pole where it reflects and less energy on the north pole.

            My understanding is that Earths orbital parameters change only over thousands of years, which give rise, eg, to the Milankovitch cycles.

            Nate says: ‘My understanding is that Earths orbital parameters change only over thousands of years, which give rise, eg, to the Milankovitch cycles.’

            Your understanding is wrong. The Milankovitch cycle theory speculates that the earths orbital parameters vary in order to create the pattern of glaciations and interglacials we have seen.

            It doesn’t say squat about there not being any other shorter period effects that vary earth’s orbit. In fact, scientific understanding of how gravity works demands there be other orbital variations. Anybody halfway familiar with the issue understands that. Those who think it doesn’t matter simply say its too small to have an effect on our climate. They don’t ignorantly say it doesn’t exist.

            And of course how small is too small? Fact is nobody knows. Gases are incredibly sensitive to any kind of forcing to a point many believe the movement of gases is chaotic in nature. We don’t understand the effects of magnetism on our atmosphere nor do we understand high frequency light and its potential effects, nor do we understand the potential association of that to other planets affecting the sun’s gas atmosphere.

            The fact is Nate, you are using an illogical argument to argue for your point of view and you are reduced to that sort of illogical argument because you can’t quantify the effects of what you believe affects climate either.

            Hmmmm, perhaps English isn’t your first language. Thats what I said. The Milankovitch theory doesn’t rule out other effects as you were attempting to do so by saying thats the only way changes occur.

            Put a large number of external variable into effect, magnetism, gravity from the entire universe, sunlight, solar cycles, cosmic radiation then mix it with a chaotic or near chaotic gaseous atmosphere with the phase changes of water, aerosols, carbon dioxide, methane, and you probably get some random walks of climate and huge amounts of momentum occurring for out of equilibrium conditions caused by a variety of forcings of all sorts. It seems idiotic to pin the entire fate of the world on one unproven theory over all others. It was idiotic 32 years ago and its gotten nothing but more idiotic since as the initial projections of doom and gloom have failed to substantially materialize.

            Meanwhile IPCC science has cranked back from 1.5c to 4.5c warming to .8c to 2.5c. In my trade when we saw such events we realized that eyes were just cracking open on an issue and that more likely than not the difference would continue to widen.

            And thats pretty scientific of a concept as its well known how stubborn and invested folks become and how they resist change. In fact the whole of excite about a little global warming is symptomatic of resistance to change whether it be good or bad.

            bill,

            Here is what I see in IPCC AR5 WGI SPM page 16 bullet point 2.

            https://www.ipcc.ch/site/assets/uploads/2018/02/WG1AR5_SPM_FINAL.pdf

            The equilibrium climate sensitivity quantifies the response of the climate system to constant radiative forcing on multicentury time scales. It is defined as the change in global mean surface temperature at equilibrium that is caused by a
            doubling of the atmospheric CO2 concentration. Equilibrium climate sensitivity is likely in the range 1.5°C to 4.5°C (high
            confidence), extremely unlikely less than 1°C (high confidence), and very unlikely greater than 6°C (medium confidence).

            I read the entirety of chapter 12 actually; not just one section. In fact the SPM reference I gave you explicitly points you to Box 12.2 beginning on pg. 1110 of the ARG WGI Physical Science Basis. It states 1.5-4.5C there too.

          • Nate says:

            Bill,

            ‘better to just absorb what the politicians approved in the summary document.’

            You ask us to do work to confirm or disprove information that you’ve simply made up, and cant be bothered to check yourself.

            Par for the course with you.

            ——————–

            You can’t get chapter 12 right unless you first pin down chapter 10. There you will find the .8 to 2.5.

            Chapter 12 then speculates on longterm feedbacks when there is no consensus on how much warming will occur and has occurred as a direct result of radiative forcing. Its a premise necessary for Chapter 12.

            Here is more reading on the topic.

      As a relative simpleton I would like to ask a simple question.

      Could the shutdown of America have led to an immediate effect on the jet stream leading to these change of temperatures. I always thought that the ever increasing methane levels over the country might also have an effect.

      I also wondered if the rapid movement of the magnetic north pole might also be signalling something deep within the mantle. On top of everything is it the year for increased volcanic and earthquake activity?

      • Scott R says:

        Hey Brian,

        The change to meridional jet stream flow was inevitable. The arctic was like a coiled spring of negative energy. The strong jet stream locked up the cold air all winter. When it was released, we saw the arctic spike in temperature and USA 48 drop. There is no relation to man made gases.

      • bdgwx says:

        The global shutdown won’t have a significant effect either way.

        There is little evidence to suggest that Earth’s magnetic field has any meaningful affect on the climate today.

        As for the jet stream the amplified warming in the Arctic region may lead to what is called quasi-resonant amplification of the polar jet. This a long term process though. And it is still heavily debated in academic circles.

          There is little evidence to suggest any specific thing is affecting our climate. And heavy debate exists regarding all the various potential mechanisms. . . .maybe not in academic circles as much but academic circles largely get all their science funding from a single source.

          • bdgwx says:

            There is a mountain of evidence that says grand solar cycles, Milankovitch cycles, clouds, aerosols, dust, biological activity, greenhouse gases, ocean currents, continental positioning, CFCs, land use changes, land-albedo feedbacks, ice-albedo feedbacks, agriculture, and I myriad of other things do IN FACT have an affect on the climate. None of these are disputed in any significant way.

            Things that are significantly disputed are magnetic fields and galactic cosmic rays, etc.

          • bill hunter says:

            Bdgwx, lets confine the discussion for a moment to discussion of the solar output, since you seem focused on that. Quite honestly I haven’t studied this aspect but on the surface I am hearing that solar output varies by .1% output during solar cycles which amounts to 1.4 watts/m2. Since we have only been able to accurately measure this outside of the atmosphere I suspect the data record to the current degree of accuracy is only 40 years long. And since water vapor accounts for by far the lionshare of the greenhouse effect why would not water vapor respond to solar input?

            As an auditor my audit flags started flying high and red when I heard from the science community no less that all the water vapor in the air came from a few watts of CO2 greenhouse effect and the effect of a ~1365 watt sun was being completely ignored. So a doubling of CO2 is supposed to produce another 3 something watts of CO2 forcing from which roughly 1/4 of which has occurred in the satellite era, amounting to about .8watts, less than the change of a solar cycle.

            So what am I missing? And thats not to talk about the fact solar cycles affect high frequency light as a wattage percentage far more than overall wattage. But I already know you don’t have much to say about that because of ignorance of what that might imply.

            And forget about dividing the solar output by four which is a favorite ploy in this discussion. Fact is most evaporation and convection occurs during 1/4 to 1/2 of a day on 1/4 to 1/2 of the planet surface at a time. And as such I am not talking about unproven insulation-making multiple layers of a gas blanket I am talking only about the well established effect of having warm greenhouse gases in the sky in one single layer.

            Where I debark from the runaway greenhouse effect train is how all this is orchestrated instead by a layer of CO2 above the action layer. If you have some lucid comments on this very specific view of the situation I would be quite interested.

          • bdgwx says:

            bill,

            Where are you getting claims that clouds and now the sun are “completely ignored”? I’d like to review where these claims are coming from.

            Anyway…a 0.1% change in solar output equates to about 1360 * 0.001 = 1.4 W/m^2 change in TSI. To convert this to the radiative forcing at the surface you divide by 4 to account for the fact that Earth is a sphere and then multiple by 0.7 to account for Earth’s albedo. This gives an RF of 1.4 / 4 * 0.7 = 0.25 W/m^2.

            But that is the trough-to-peak change. The peak-to-peak, trough-to-trough, or mid-to-mid change is 0 W/m^2. Likewise the residual change over several equal cycles is 0 W/m^2. So the net change in solar forcing over several cycles is 0 W/m^2.

            Long term solar forcing is actually driven by the grand cycles. It can produce up to 0.25 W/m^2 of forcing for several decades. The modern grand maximum peaked around 1960. Solar activity and solar radiation has been on a secular decline ever since.

            So the 2xCO2 forcing about an order of magnitude higher than the forcing from the solar grand cycles.

          • bill hunter says:

            why divide it by 4?

            CO2 forcing in terms of evaporating water vapor is simply wasted wattage at night where the surface is cooling faster than the atmosphere. And evaporating water would seem to be how you get greenhouse effects feedback.

            Thus while “the greenhouse effect” is produced by greenhouse gases over the entire surface of the planet, and average insolation tells you the equivalent sunshine. It doesn’t need to follow that evaporation is a mean surface temperature thing.

            Do you have a study that elucidates on this issue a bit more? Some times when you just run with averages you don’t get the same results.

          • bdgwx says:

            TSI is measured perpendicular to the surface. To convert it into the flux over the entire Earth you divide by 4. The division by 4 occurs because the Earth is a sphere so its surface bend away from the Sun’s rays. The rays spread out over larger and larger areas the closer to the poles you get. Then, of course, only half of the Earth is lit at any given time. So the average flux Earth receives at TOA is actually 1360 / 4 = 340 W/m^2. And the amount taken up by Earth is 340 * 0.7 = 240 W/m^2 with 100 W/m^2 being reflected away.

            ——————————–
            You didn’t answer the question bdgwx

            I wasn’t measuring global mean TSI bdgwx. You only need to do that to measure pre-feedback sensitivity.

            I was measuring the increase in TSI where water is evaporating, not where just the cooling is slowed down. Water doesn’t generally evaporate at night because the surface is cooling, water is condensing. Its also probably the case that large areas of the sunny half of the globe doesn’t get sufficient light to evaporate much water either. Probably 3/4’s of global mean forcing doesn’t do squat if its evenly distributed. You need to get it under the 1365 watt sun where the surface is warming fast for it to kick arse on water vapor feedback.

            Like I asked do you have study that explicitly refutes what I am saying? You just parroting the CAWG propaganda line simply doesn’t impress me. I like to see the science on it.

          • bdgwx says:

            ———————–

            The topic I was discussing when you suggested dividing it by 4 was the evaporation of water which is recognized as a feedback twice the original forcing.

            Dividing by 4 is what you do to figure mean global TSI. But what I am talking about is a focused concentration on evaporating water and if you spray your heat texas sharpshooter style you aren’t going to get as much evaporation as if you aim the heat at the water at the same time 1365watts of TSI is aiming at the water.

            So to be abundantly clear as it seems necessary. I understand how you divide by 4 to get average TSI across the entire globe. But its a texas sharpshooter fallacy to claim you need to do the same thing to estimate the rate of water evaporation increase. Basic physics of water evaporation should tell you that.

          • Dr Roys Emergency Moderation Team says:

            bdgwx chooses not to understand when you explain that dividing by four, whilst all well and good mathematically, doesn’t represent the correct physics that exist in a real-world scenario.

            bill said: But its a texas sharpshooter fallacy to claim you need to do the same thing to estimate the rate of water evaporation increase. Basic physics of water evaporation should tell you that.

            I never said you divide by 4 in regards to quantifying anything with evaporation. What I said is that if you want to quantify the RF corresponding to solar TSI changes you use the formula RF = delta-TSI/4 * 0.7. Also understand that CO2’s RF almost always includes the WV feedback unless specifically noted otherwise. In other words 2xCO2 at 3.7 W/m^2 includes the WV feedback.

          • bdgwx says:

            DREMT,

            The amount of energy Earth receives in one year is 1360 W/m^2 / 4 * 510e12 m^2 * 1 year = 173e15 W-years. That is real physics. If you don’t divide TSI by 4 you get the wrong answer. That is wrong physics.

          • Dr Roys Emergency Moderation Team says:

            …and the amount you get on a second by second basis is received only over the lit hemisphere. And that is the correct physics.

            I don’t believe that CO2 is the only way that water vapor gets into the atmosphere and I don’t want you to believe that either. Would you like to explorer this topic further?

          • bill hunter says:

            sure lets explore this. i may have assumed you were a believer in the CO2 is the climate control knob theory that is the essential basis of the ECS figures you bandied about from Chapter 12.

          • bdgwx says:

            Here is what the science says in regard to WV and how it relates to long term changes in global temperature.

            It is a condensing gas. That means it evaporates into the atmosphere and precipitates out of the atmosphere via phase changes. These phase changes are determine by pressure and temperature. And as you probably know pressure and temperature are also coupled with each other. For each temperature and pressure level there is a maximum amount of WV that a parcel of air can hold. The smaller the spread between the temperature and dewpoint the more/less likely it is for H2O to condense/evaporate. The larger the spread between the temperature and dewpoint the less/more likely it is for H2O to condense/evaporate. The effect this has on a planetary scale is to create a stable equilibrium between WV content and temperature. Perturbations away from this equilibrium result in processes that drive WV content back towards the equilibrium. And finally these evaporation and precipitation processes are very rapid.

            What this means is that WV, on its own, cannot force a change in temperature. The reason is precisely because it is a condensing gas. Perturbations above/below the equilibrium set by the temperature tend to self correct before the energy imbalances they cause have enough to time to change the temperature. This is the a crucial concept.

            But…don’t hear what I’m not saying. That does NOT mean that WV cannot amplify a temperature change. It most certainly does. But it requires another agent to force or catalyze that change first. Once a temperature change has been catalyzed by something else the GHG of the WV works to amplify that change.

            There are many agents that can catalyze temperature changes on their own. These include but are not limited to changes in solar output, changes in stratospheric aerosols, changes in albedo, changes in non-condensing GHGs, and many more. What sets WV apart from CO2, CH4, etc. is that it is condensing whereas the others are non-condensing. The amount of CO2, CH4, etc. that the atmosphere can hold is NOT dependent on the temperature. There is no natural equilibrium in which those gas are forced to condense out…because…they are non-condensing in an atmospheric environment.

            CO2 is not the climate control knob. It is only a participant in the climate control knob. It must be considered in totality with all of the other agents that can catalyze temperature changes. There can be periods in which CO2 dominates over all of the other agents and periods in which is is quiescent. We just happen to live in an era where it is dominating.

            If there is something you don’t understand or something you feel that I have not articulated well then please ask questions. Don’t presume I believe something that I don’t. And, of course, if you feel that I have not described what science understands about WV correctly then please chime on that too.

          • bill hunter says:

            as you know you can’t have your cake and eat it too.

            I have since a young child had a compulsion to experiment. I don’t know where the compulsion arose but I was never satisfied with an explanation without understanding the role of every variable thoroughly and understanding how things changed with changes in experimental subject and all it variations of its variables.

            I can appreciate the physics that goes into all of it as physics was always my favorite among the sciences. However, I gravitated into natural sciences rather than physics with their much greater complexities all the while keeping an open mind to all the possibilities that such complexities opened up.

            The following article probably best describes the uneasiness with the popular version of the effects of CO2. I have been squarely in this corner of concern practically since the first day I took an interest in climate science since about 14 years ago. The reason was I was already dealing with the exact same issue that Dr Curry discusses here in my area of natural science for nearly a decade before taking up an interest in climate science.

            LOL! Talking about jumping to conclusions. If you mention YD,8.2K,LIA you re talking about much longer phenomena running into centuries. Its just not as obvious as a modern instrument record anomaly that doesn’t have the luxury of centuries. So you have to deal with unobserved anecdotal and proxy data.

            Then you talk about Santer’s 17 year fingerprint which at the time was thought to be sufficient to define climate and single it out against natural variation. But multi-decadal was just ignored though it was right in front of them at the time.

            So do we set the bar at multi-decadal? Well if we do we still have a few decades to wait out. What if its multi-centennial?

            I can agree that CO2 provides some modest but very important climate stability but winning in the long run even at the multi-decadal bar isn’t saying much considering the half life of it is multi-decadal.

            But there is much more in the comment section of Roy’s previous post, mostly by Chic Bowdry and Bdgwx.

            Read IPCC AR4 and AR5 WG1 main reports on the topic. Much is there including an acknowledgement that CO2 would decay quickly to about half its pulse and then more slowly.

            Near as I can tell all the sinks that would delay decay would be the dying vegetation and animal life that croaked from a lack of CO2 as they would croak and the carbon they have sequestered would rot slowly. but the ipcc demurred from such a depiction and instead declined to offer an explanation for an extended second half decay.

            What you are looking at is model output. Even the scientists at IPCC don’t believe that stuff. Not that its way off, but quite simply all this isn’t well understood. If you don’t read the discussion thoroughly in the IPCC reports you will not be able to put those graphs in the correct context.

            ===============================

            Of course you will! Why? Because you are overly impressed by models.

            I have worked with difficult models for almost 40 years. I don’t know anybody who has done that with models under development who is anywhere near as impressed as you are.

            That said, IPCC science consensus believes about half of a 400ppm peak would decay in a few decades. The graph you are looking at sustains the use of fossil fuels forever and different levels and different slopes so the graph is not going to show how fast a spike is going to decay if fossil fuel use was completely replaced by renewables.

            So I can’t say the graph you are looking at is actually saying any thing different than what I am saying. Fact is using half lives of a few decades would leave some trace of CO2 in the atmosphere in thousands of years (assuming no other changes in an ever changing atmosphere) strictly using the c14 decay model. And of course their may be soils that take up carbon in methane deposits that take eons to leak back into the atmosphere. Disregading those ‘temporary’ sinks the modelers are using for scare tactics, they also like to scare you into thinking we are going to start uncovering some of the sinks and sending them into the ocean even faster.

            It all sounds like to me like a good thing. What really sounds bad is calling our current 400ppm a spike and wishing it would all disappear.

            But if you meant a 400ppm spike in 130 years from now well thats not nearly as bad but who wants to go back to the LIA?

          • bill hunter says:

            thats somewhat fair. its good to know from the naaratives that they feel a lot more confident about the first statement than the second one because looking the wide ranges put forth via the pulse resulting in a significant increase of biota sinks, which makes up about 90% of the temporary sinks.

            While the IPCC doesn’t get into details on that due likely to wide disagreement it does seem likely that if the biota sinks don’t enlar ge or shrink (which many of the doomsday folks contend); than that large fraction in the end might disappear as fast as the first half.

            OTOH if they do significantly enlarge (massive greening) then the second half of the pulse might be around for a long time to come. Which would likely be a good thing, feeding a growing population.

            in fact it might be so good, like better than now we might become overly addicted to it. imo, we are already addicted to good times.

            None of it is on land, all of it is in the atmosphere. A surface station in Denver, Colorado would be at an altitude of over 5000 feet into the atmosphere whereas one in Bolivia would be over 15,000 feet. Furthermore, there are temperature inversions near the surface that can be misleading.

            The satellites cover 95% of the planet’s surface whereas surface stations sparsely cover the 30% of the surface that is land area. The oceans are really sparsely covered. Those calculating surface averages have resorted to fudging the temperatures for areas in a climate model based on an interpolation and homogenizations of real temperatures up to 1200 miles away.

            The surface record is so fudged it has become unreliable.

        sys…”Claptrap: 0.14 C per decade of warming over 41 years”.

        Once more for the bean-counters who create graphs without looking at the underlying contexts.

        The first 18 years of the UAH time series indicates global average anomalies colder than the average to that point from 1979. It was not till 1998 that the anomalies broke through the baseline and became true warming.

        Even at that, there was an 18 years flat trend following the 1998 EN spike and it was another EN spike in 2016 that drove the trend upward again. Since then, the global average has been working its way down in fits and starts.

        How can anyone claim a 0.14C/decade linear ‘TRUE” warming trend when 18 years was below average and another 18 years had a flat trend? What happens if the anomalies drop back to the baseline? How then will you calculate the trend?

        These trends are not calculated using a best fit of the data over the entire range since that could not be done using end points between 1979 and 2020. They are calculated using algorithms that ignore the physical contexts. They operate on the data alone without consideration of the contexts from which the data came.

        The only way a 0.14C trend could have been calculated for TRUE warming would have been a scenario in which the UAH trend began at the baseline in 1979 and continued upward till the trend line intercepted the y-axis after 40 years at 0.56C. That has not been the case.

        UAH is using the 0.14C/decade trend on the data only but they explain the context in the 33 year report. They explain the aerosol cooling over the first 18 years, they explain the change to true warming after the 1998 EN, and the following flat trend.

        The IPCC corroborated 15 years of the flat trend. However, UAH must scientifically supply the trend of the data which alarmists have pounced on as proof of anthropogenic warming.

        • Gordon Robertson says:

          ps. the bean-counters are not a reference to UAH or the graph on this site. It’s a reference to layman statisticians who input UAH data to their Excel spreadsheets, oblivious to the conditions underlying the data they blindly plug into their calculators.

        • Gore & Co. says:

          who is this grobertson guy? trends are calculated, not derived by eye. how can someone not know this?

          & without aerosol cooling, uah global warming would be even higher.

          • Svante says:

            He likes his PRATTs, for example that base lines are the gold standard for “true warming” (they are arbitrary).

            https://rationalwiki.org/wiki/Point_refuted_a_thousand_times

            A point refuted a thousand times, commonly abbreviated as PRATT, and called a canard outside of this website, refers to a point or argument that has literally been refuted so many times that it is not worth bothering with.

            It is a common phrase on Internet forums — as debates have a tendency to go in circles. Once people have refuted a point the first thousand times, it’s hard for them to muster the motivation to do it again

            These assertions are mostly very easy to refute, but remain persistent arguments due to ignorance.

        • Robvert Ingersol says:

          “continued upward till the trend line intercepted the y-axis ”

          Very sciency with ‘intercept the y-axis,’ but seems confused on which axis that is.

        • E. Swanson says:

          Gordo completely fails to understand “baseline” and what the trend means. The baseline is calculated as the average over some “base period, which is 1981-2010 for the UAH data. The fact that there are more data points below the average in the beginning of the record and more above later just tells anyone who’s listening that there warming going on. The trend calculation does not rely on the baseline in regard and the trend is the important variable, not this month’s particular value above (or below) the baseline.

          Moron.

          • bill hunter says:

            I didn’t get such a far reaching speculation as you did Swanson from Gordon’s comments.

            A baseline should be something real like a climate equilibrium, not some point in time where it started allegedly just started warming. We don’t even know if that’s the case or not.

            If I embrace mainstream climate science concepts of feedbacks proceeding for centuries after a climate change, I can easily make sense of the idea that warming actually started at the beginning of the 18th century. The advance of glaciers continued for another 150 years after thermometers started rising slowing the warming via radiative albedo feedbacks. However, eventually the system momentum caught up glacial advance slowed and the glaciers began to melt accelerating warming. Fits mainstream science projections on albedo feedbacks quite well and does it in a more pure manner as its not pointing primarily at sea ice changes which may not have positive feedback. The glaciers though would seem to be far more likely to represent positive feedback.

            So Gordon seems right on the mark calling out baselines on dates alone.

          • Svante says:

            The World Meteorological Congress, WMO’s top decision-making body on Standards, approved a resolution that WMO will update the climatological Standard Normals for operational purposes every 10 years and will use 1981-2010 as the current base period. However, it will retain 1961-1990 as the historical base period for the sake of supporting long-term climate change assessments.

            “In a world in which the climate is changing rapidly, we need to update the climate normals more frequently than we did in the past to keep them useful,” said Thomas C.

          Even the alarmist IPCC declared a flat trend from 1998 – 2012. How do you manage a 0.4C/decade trend from 2008 when it’s in the middle of a flat trend? If you look at the UAH data, the flat trend carried on till 2015. Any claim of a 0.4c/decade trend has to begin at 2015 then take into account the negative trend after 2016.

        There is generally a linear trend combined with “iregullary regular” 3.6-year wave. The current downward trend comes a little bit sooner than I expected. There are similar shorter cycles in the history but I do not feel sure that the temperature does not turn up again for some limited time.

        • Tim Hartan says:

          Your “iregullary regular” cycle is the El Nino/La Nina cycle. Models are predicting La Nina is coming, but the models aren’t always correct.

          • No one should take any notice of BOM their forecasting is appalling because they over ride everything from a climate model which gives the wrong answer. In the case of weather they would be better off saying the weather tomorrow will be the same as today, for one year out they would be better saying it will be the same as last year, and for the still longer out there is an 10-11 year cycle, a 50-60 year cycle and an 100-120 year cycle.

          I like to tease the trendies by bringing up the fact that the anomaly is the same at certain points as the wave cycles. Kind of like a broken watch being right twice a day.

          The thing about trends is they wander all over the place depend on what endpoints one cherry picks. But it is an unwavering fact that the average temperature last month is the same as it was on the down side of the El Nino in 1999. It doesn’t matter what the temperatures have been in between, because no one knows what the temperatures will be going forward.

          • barry says:

            Yes start and end points matter, except when the sample size is so large that it makes barely a difference if you add another month or year, even an outlier.

            The error with a lot of prognostication on linear temperature trends is that the time period is too short. The other fault is a lack of concession to statistical significance, and what it really means. EG, if a trend fails statistical significance, that doesn’t mean there is no trend. Proving the failing to disprove the null hypothesis doesn’t mean that the null hypothesis is then true.

            And since you didn’t put yourself on that list means all you do is copy what people in authority say. Several of the leading scientists considered to be skeptics or deniers by the blind believers concede the case for multi-layered greenhouse effects isn’t at all described in physics. Its instead simply intuitively believed as is in seems perfectly plausible without having a described process of taking heat ostensibly trapped (by an unnatural concept of a static atmosphere) high in the atmosphere back to the surface to warm it. Sort of a 50,000 foot leap of faith.

            But people have definitely believed, including scientists, far wilder things. And in fact those same scientists remain concerned that life on the planet will not evolve fast enough to keep up. . . .which includes evolving from those scientists who have tended to believe in some pretty wild stuff.

            Gee look at the response from the government putting in a few dollars in the desert to investigate UFOs, it bred generations of true believers.

            Actually getting a bit into psychology, the average guy who doesn’t believe he is too smart actually is smarter than somebody who believes he is smart. Why? Because he can see the truth.

            Myself, I am not smart; but it does seem to me to be logical we should be spending our resources less on climate and more on pandemic responses. And no doubt that will be laughed at by the money grows on trees crowd.

            But bottom line is while RSS offers up an alternative reality in satellite temperature recording it is largely based upon climate modeling to provide for satellite drift. Thats fine and Roy is good with it though he prefers the UAH method of relying on improvements in satellite technology (Cadillac quality).

            But what arises out of RSS using climate models to adjust their temperature record makes them less qualified as a means of vetting the climate models and more particularly explanations for model inaccuracies. Most of the surface records have traveled this route with climate model sea level rise having downstream effects on ocean temperatures. Now none of that means the records are wrong, it only means one cannot consider them independent for the purpose of vetting what is really happening with heat accumulation on our planet. Politics is always pushing for a single mind set for obvious reasons. Science is supposed to rise above that.

            RSSv4 does not use a climate or global circulation model to make adjustments.

            RSSv3 did. The academic community criticized the method so they changed it. The v4 method says that the v3 method was underestimating the warming.

          • bill hunter says:

            hmmmmm, you don’t think academic criticism and matching to model output had anything to do with the decision to rely on out-of-date technology?

          • bdgwx says:

            bill,

            First…I think you’re playing too loose with the term “model”. RSSv4 still uses a model for the diurnal correction just as UAH uses a model to make the same correction. It’s just that RSSv4 uses a different kind of model as compared to RSSv3. Remember…a model is a collection of rules, procedures, and algorithms which provides useful insights about the nature of reality. It doesn’t have to be a GCM.

            Second…RSSv3 was not matching to the global circulation model output. It was using the GCM computed diurnal trajectory at each grid cell to estimate the correction factor.

            Third…I’m not sure what is out-of-date here. The criticism wasn’t that RSSv3 was using out-of-date technology. The criticism was that the approach RSS took at the time was thought to have substituded one bias for another. They listened to the community and changed their approach.

        • Bindidon says:

          Let us add for the dumbest that any spreadsheet will show us, for 1999-2015, a UAH6.0 LT trend of

          0.06 ± 0.02 C / decade. Low for sure! But flat??

          The flat trend in fact is rather for 1998-2015:

          -0.01 ± 0.02 C / decade.

          Why this? Simply because the period now includes all anomalies since January 1998, what lets the period start with very high values, and thus reduce the trend.

          The inverse would happen if, while starting with 1999, I would include the year 2016, containing the highest anomalies since December 1978, what increases the trend, which then becomes

          0.13 ± 0.02 C / decade.

          But all these trends can’t invalidate those computed for the periods since 1999 resp. 2009.

          Unlike Robertson, a spreadsheet doesn’t do eye-balling and guessing.

          It simply computes trends according to theories developed by Gauss 200 years ago… and used by Roy Spencer as well.

      Hi bohous,

      I believe the length of this 3.6 wave is very typical. Can you see my post here?

      https://www.facebook.com/100000276969216/posts/3176979828987885/?d=n

      Note the 3.6 year cycle is 1/3rd of a solar cycle. Not only are we headed for the down beat of the 3.6 year cycle, but we are also headed for the down beat of the 11 year cycle which occurs approximately 3.6 years offset from the solar minimum. The 11 year cycle is not enough to explain the linear trend you observed. In actuality, the tropics have a very complex 42 year cycle as well, or 4 solar cycles. The amplitude of each part of the 3 wave pattern that occurs each 11 years can be predicted. The first wave I’ve assigned red, the 2nd green, third blue. They follow a pattern like this: low, mid, high, mid, low. Blue is the strongest wave. Red is 3.6 years offset from it. Green is offset by 1 2/3rds solar cycle. We are actually coming off of blue low right now. Next is red low which is the weakest wave. Using this pattern, we can predict that the 42 year cycle will bottom in approximately 12-13 years.

      Not coincidentally, the 60 year cycle is also getting ready to drop. It was the aligned 60 and 42 year cycles that caused the modern maximum in the first place.

      I confirmed this low / mid / high / mid / low pattern goes back to the 1800s using HADSTT3 data.

    What is the global average lower tropospheric temperature (LT) anomaly? How is it calculated and is it a meaning statistical measure?

    • Bindidon says:

      Joel Brown

      A layman’s (!) opinion: UAH data for one year is represented by 12 monthly grids of 72 latitude bands, each containing 144 longitude cells. The 3 northernmost and southernmost latitude bands in the grids do not contain valuable data.

      For each cell, the monthly average for the reference period (currently 1981-2010) is computed, and the monthly cell anomalies are obtained by subtracting this monthly average from the absolute data.

      Then the global monthly anomalies are computed by averaging all cells in each latitude band, and finally performing a cosine-weighting over all latitude bands.

      Anomaly data for e.g. the year 2019:
      https://www.nsstc.uah.edu/data/msu/v6.0/tlt/tltmonamg.2019_6.0

      Lower tropospheric temperatures are derived from measuring the intensity of microwave radiance of oxygen molecules by instruments on board satellites looking Earthward. Satellites scan the globe and get near full coverage over a few days. The highest latitudes at the poles are not covered. The radiance measurements are mathematically converted into temperature.

      The instruments read very deep swathes of the atmosphere. The lower tropospheric temperature is a swathe about 12 kilometers deep, weighted most strongly at about 3km altitude.

        I get a big laugh.

        Roy Spencer has himself explained years ago that between ‘measuring oxygen emissions’ and presenting their transformation into absolute temperatures, there is sometimes a gap.

        And the gap here is the ocean: O2 emissions above its surface in the 60 GHz band are subject to extreme bias.

        This is the reason why UAH6.0 LT does NOT take surface temperature computations into account.

        Unfortunately I forgot to sync Firefox at that time and the link was lost.

        Another indication of measurable but useless data is all places in the lower troposphere that are above high altitude surfaces (e.g. the Andes, the Himalaya, the Tibetan Plateau, etc.).

        A further interesting point concerning measurability vs. usefulness is the difference in handling pole-near latitude bands between UAH6.0 and UAH5.6.

        If you look at UAH’s grid data in both contexts, you will see that while UAH6.0’s 2.5-degree grid does not contain valid data for 82.5N-90N or 82.5S-90S, UAH5.6 however did very well.

        Please compare e.g.

      If the global mean temperature would warm and cool, warm and cool, warm and cool, then the trend over 1979-2020 would be 0.0 C / decade, and not 0.14 C.

      The last anomaly below 0 C wrt the mean of 1981-2010 was, if I well do remember, that of March 2012, i.e. about 100 months ago.

      It’s as simple as that.

      • Rob Mitchell says:

        Bindidon, why do you think global temperature rises and falls should all average out in just the previous 41 years? I don’t think there is any one regular climate period one can pinpoint. There could be a 5 decade warming period followed by a 3 decade cooling one, or vice-versa. You don’t actually think like Bill Nye that there is something unusual about the “rate of warming” during the past 4 decades do you?

        Gore & Co., those who are devout believers in green energy are the ones most upset with the film. And the reason being is that the film is revealing what goes into producing green energy. The vast majority of the public has no idea about all of the mining that is necessary to produce solar panels and batteries for electric vehicles. They are also not aware that wind and solar requires a backup coal/natural gas plant built to support the renewables. Wind and solar energy fluctuates, and a steady source of energy has to be available to make up for the periods of no wind or no sunshine. This film is an eye-opener for progressives because they’ve always believed renewables will save the planet.

            (i) It refers to the 1951-1980 mean, which means they are using GISS data. GISS data shows that 2019 was 0.98C warmer than that mean, not less than 0.6 as the graph shows.

            (ii) It says “you should be here”, pointing at the worst-case scenario. It should be highlighting the RANGE between extreme values. +0.98 is right in the middle of that range.

            So it turns out that judging the content and judging the poster led to exactly the same conclusion. Go figure.

            What does that tell us? The physics programmed into 30 year old models is pretty good and that our assumptions of human behavior are poor.

    You can find the plot here: http://www.bryanleyland.co.nz/global-temperature-prediction.html

      Yes, El Nino and La Nina events affect global average temperature on interannual time scales. But, they do not explain the long-term warming trend.

    • gbaikie says:

      So, you got a “cheat” on predicting next month’s global temperature?
      Is going to down or up?

      So, generally, the Southern Hemisphere is about 1 C colder than Northern Hemisphere. And Southern hemisphere warms Northern Hemisphere.

      Or as said, the tropical ocean is heat engine of the world, but tropical ocean warms Northern Hemisphere, more than Southern Hemisphere. Or helps explain how something colder can apparently warm something warmer {the warmer tropical ocean warms both cooler hemispheres, but warms Northern more than Southern hemisphere}.

      Why does tropical ocean warm northern Hemisphere more than Southern Hemisphere.
      No doubt it complicated. But would say roughly, because, ocean warms land and there is more land in northern hemisphere.

      And more interesting question is there variance or factors alter this, so northern hemisphere is warmed less or both hemispheres are more equally warmed by the heat engine of the world?

    The trend is now +0.1351 with an error of 0.0068.

    The trend line is at +0.33 so this month was 0.05 above the trend line.

    Given that we are toeing the line of +0.13 and +0.14 and that the stratosphere has warmed in recent months I expect a drop back to +0.13/decade in the coming months.

  14. Richard M says:

    This drop follows what I’ve been saying for a long time. All we have seen in recent years is the effect of natural factors such as ENSO pushing up global temperatures. There is no indication that the climate baseline has changed this century.

    In April the effect of the ongoing Pacific El Nino and the winter AMO driven Arctic enhancement were both in effect. Next month the Arctic influence will likely fall again. Due to the lag that occurs with El Nino, we will continue to see those effects for a few more months even if it fades away.

    My prediction for this month was .40-.45 so we got more cooling than I expected. Next month will probably be in the .30-.35 range.

    Overall, if the ENSO returns to neutral we have a chance of returning to the 21st century baseline by September.

    • Midas says:

      Compare the UAH 2001-2019 average to the UAH 1980-1999 average, and get back to be with that comparison. I suspect you won’t perform the calculation because you already know how the result will look.

      • Richard M says:

        Midas,

        Why would anyone compare periods that are completely different? Most of your first period was during a -AMO while also containing both cooling major volcanic eruptions. The second period was during a +AMO. Did you intend to highlight the key reason why it has warmed?

        • Midas says:

          Don’t you think you need to look for another excuse for the southern hemisphere and the tropics? And why didn’t you factor in the generally negative PDO from 1998 to 2014?

          • Richard M says:

            Midas, I see all you have is denial. The PDO usually shows up negative during La Nina events. When this is factored in the PDO was positive from 1976-2006, negative from 2006-2014, and then positive since 2014. What you just said was the PDO has produced a warming influence on global temperature for 80% of the last 40 years.

            Thanks again for pointing out that natural factors explain much of the warming.

          • Midas says:

            As I said, the PDO was negative from 1998 to 2014. For the first 19 years of the UAH record it was positive. It has been essentially neutral since then. So eff knows how you came up with that assessment.

          • Richard M says:

            Midas, the PDO was “generally” positive until 2006. Sorry, but you don’t get to change the data. And, you also want to ignore the more influential warm cycle, the AMO. Why is that? You appear to be in denial.

      • Amazed says:

        How so?

      • Richard M says:

        G&C appears to think that ocean warming is caused by atmospheric CO2 increases. Yet, no evidence exists to support that conjecture. A more scientific view is that oceans have warmed naturally and the atmosphere has simply picked up some of that energy.

        In fact, there is evidence that changes in ocean salinity could drive changes in the ocean current speeds which in turn could lead to warming (or cooling). See Thirumalai et al 2019.

        • Gore & Co. says:

            gore…”theres no evidence the ocean has warmed
            naturally. none at all”.

            The oceans have been recovering naturally since the end of the Little Ice Age circa 1850. There was a heck of a lot of ice created on the planet during the LIA from roughly 1400 – 1850. There were enormous glaciers created in the Alps alone. It takes a long time to melt those glaciers given new winter deposits of snow and the oceans cooled significantly during that period.

            Cooler oceans = less CO2 in the atmosphere but the IPCC missed that one when they set a baseline of 270 ppmv based on ice cores in Antarctica. Why did they not take samples from ice cores in the Alps where CO2 levels were likely higher.

          • Gore & Co. says:

          • Richard M says:

            Gordon,

            I agree that there has been 300+ years of warming that cannot be explained by CO2 increases. The reference I provided does hint at one possible cause of this recovery. That is, changes in precipitation in the Amazon/Congo basins leading to ocean salinity changes.

            What drove these rainfall changes could be solar related. Changes in the distribution of energy in solar radiation frequencies such as described in Lean 2018 are one possibility.

            I always find it interesting that when anything other than man made emissions provide evidence for climate effects, all we see from one specific set of commentators is denial. No interest in real science.

    For me, the UAH L. Trop is the best data to understand global warming because it is not tied to any climate model and satellites are better than the trash thermometers that have some el nino and not others. Also, it is apparent warming is a step function defined with excursions at major El Nino events and thus I hypothesize another long hiatus before the next step. It would be exciting if the next step were to be negative (cooling) or minimal (hiatus).

    In literature and popular culture the hysteria for climate is falling apart. Scientists are pointing out IPCC has stepped to far by adjusting sensitivity up in new models (https://www.nature.com/articles/s41558-020-0764-6), Michael Moore and Gibbs turned on the left in Planet of the Humans, which is a positive because I dont agree with their anti capitalism views, but I have real respect for them being consistent. Criticism from within always has more power.

    I dont believe we can drift into a new dark age mostly because there are to many channels for free speach and distribution of power to citizens to close them all down.

      I don’t think UAH is the best. They are all estimates with strengths and weaknesses (using modeling doesn’t automatically confer weakness), abd UAH seems to be the biggest outlier. UAH data set has undergone the most significant changes out of all the major data sets (perhaps equalled by RSS in its latest revision). So non-modeling has not helped it have better data than the rest, otherwise those revisions should be very minor, not the most profound of all others.

      There are many datasets that are not coupled with GCM models. Note that I’m assuming by “climate model” or you mean global circulation model.

      and satellites are better than the trash thermometers

      Can you provide us the RMS error on the monthly anomalies from UAH and compare it to those from traditional surface datasets, balloon datasets, and reanalysis datasets?

      • Aaron S says:

        I’m not saying that error bars (precision) are the differences that swing me- open to hearing the answer from you though and more importantly why do error bars matter?

        Also, I can describe the differences in accuracy between data types from memory so that any inconsistent understanding I have can be pointed out by you. It is always good to test the basis of an interpretation. 1. RSS diurnal adjustments are tied to a GCM but for the most part is very similar to UAH that adjusted independently of GCM. I have no issue with either but after last adjustments RSS went up, UAH went down. Will RSS now require an additional adjustment up because the GCM from IPCC increased sensitivity? 2. RSS or UAH vs balloons. Balloons are excellent precise calibration but not global view. Last I checked UAH was slightly better match but insignificant differences. 2.5. I am not familiar with the analysis outcomes other than what I read here on this page. 3. Thermometer data has been so heavily massaged since I have followed it. There was the boat correction adding warming to the trend by cooling pre 1950 oceans, then several more adjustments up for the trend including the Karl et al that removed 97 98 el nino in an attempt to add deep warming, but it is now looking internally inconsistent after the next big 16 17 el nino showed up in the data. This is not ideal to me and suggests the researchers adjusted incorrectly. 4. You forgot glacial ice extent (and eustacy). Very low precision but better accuracy for global warming as a proxy. It shows the 1940s warming, 1970s cooling, that bust thermometer global temperature data. It also shows the medieval warming busting hockey stick from one version of the tree ring interpretation. Glaciers and sea level indicate sea level was 6m to 8m higher just 125k yr ago at only 295 ppm CO2, likely busting high end GCM estimates and suggesting moderate to low climate sensitivity to CO2 are plausible. If earth was highly sensitive to CO2 then we would be seeing faster warming, rather than a gradual moderate increase observed in RSS and UAH. The ecstatic data provide a maximum constraint on climate sensitivity.

        • bdgwx says:

          1. RSS used to use GCMs for diurnal corrections. They use a different technique now.

          2. RSS is a better match to balloon datasets. https://tinyurl.com/v5ux75g

          3. All data is “messaged”. UAH doesn’t even use thermometers. They have to use a model to first map microwave emissions to temperatures. Then they have to correct for certain biases and homogenize the data to produce a global mean. If “messaging” is offensive to you then you probably shouldn’t be relying on UAH. Regarding Karl…you should understand that his “messaging” actually works to reduce the global warming trend overall. Nevermind, that he is but one of many that publish such datasets. So if “messaging” is offensive to you then you’re going to have to live with the fact that the warming is more than is being officially reported.

          4. This is a topic for another line of discussion. I don’t see how it is relevant to measuring the global mean temperature today.

          • bdgwx says:

            Yes. All reputable surface station datasets that publish a global mean surface temperature for climate research make adjustments to produce a better result. Actually all datasets regardless of type make adjustments. This includes reanalysis, balloon, satellite, etc.

          ” You forgot glacial ice extent (and eustacy). Very low precision but better accuracy for global warming as a proxy. It shows the 1940s warming, 1970s cooling, that bust thermometer global temperature data. ”

          Here too, some sources would be interesting.

          1. A graph showing global sea ice (Arctic + Antarctic, extent + area) out of the HadISST1 data set, starting in 1950:

          https://drive.google.com/file/d/1dNTLShsJp2U9aBHuU3h4OL5tK32of9pg/view

          There will be somewhere data showing how the Greenland and Antarctic ice sheets behaved prior to the satellite era, but it is certainly in NetCDF format, not in ASCII. So I can’t show it here.

          Where do you see in such data anything supporting your claim?

          • Aaron S says:

            Bindidon,
            On the Arctic/ Antarctic graph which color is which? Antarctic is mislabeled as red I believe but I think I understand and just want to confirm. Do you have the citations for each trend you shared? I’d love to see why the 1940s are deleted from the glacial ice trends because it is unfortunately not there and is the relevant period to my statement (especially given the symmetrical smoothing eliminates most of the 1950s data into one data point without a trend). It very well maybe just the start of both data sets started in the 50s, but it is an interesting point to start a data set so my gut tells me to explore more.

            I definitely need to know more about the tide data too becuase tode trends are highly vulnerable to subsidence trends particularly in areas with modified alluvial drainage by engineers to control flooding that create meters of subsidence via reduction of overbank fine alluvial sediments. New Orleans and Mississippi River is an invalid set of data (as is most of Europe). The Mississippi Delta is a bird foot geometry for the reason it should have avulsed to fill in the subsidence gap years ago but Army core has prevented that. So it is easy to select tide data that confirms a narrative. Satellite tide data is the most relevant.

            I am not familiar with the ice extent curves you cited, but I do see the 70s cooling as a surge in red (assumed arctic) and a lag before the blue (assumed Antarctic) sea ice extent growing. It will be interesting to see if the Antarctic cooling last decade is followed by an arctic ice growth in the next few years with a flip flop of lead an lag response.

            Final point, shouldn’t sea ice highly correlate with temperatures? Especially if you weight Arctic Antarctic trends based on ice volume.

  22. Interesting that the trend has finally ticked up above 0.13C/decade. I had been seeing 0.18C/decade from other series for a long time now, and wonder a little at the inconsistency. Still do, of course, but this reduces it a little.

    In other news, the UK just went 18 days without coal being used for electricity generation, another record.

    Also, I am delighted to report that Dr. Michael Mann has just been elected to the NAS. You can all congratulate him on Twitter. It is heartening that his decades-long contribution to such an important science is being recognised so clearly.

    • Amazed says:

      Unfortunately, climatology is as much a science as astrology. Its practitioners just make stuff up as they go along. Try finding climate forcings or climate sensitivity in a real physics textbook.

      • You can find hundreds of papers mentioning both climate forcings and climate sensitivity on real physics journal sites, not to mention the flagship journals “Nature” and “Science”. I might add that I also learned about the greenhouse effect and the adiabatic lapse rate in science classes during what American persons would call “high school”. During the 1970s.

        I’m sure there are very basic reasons why the warming rates in different series would be different. I’ve just not been keeping fresh for many months and don’t like to make claims of excess precision. There are real scientists at the IPCC and now the NAS who do this sort of thing, after all.

        It only takes seconds to think up a physical explanation if you put your mind to it, rather than trying to come up with unfounded accusations to throw at scientists. For instance, altitude: An atmosphere warming due to GHGs will necessarily be cooling at its upper extremes, so a warming trend will change at altitude until it inverts to a cooling trend. Mystery solved, and not a tinfoil hat in sight. See how easy?

        • Amazed says:

          So you agree that real physics textbooks do not contain the wondrous forcings or sensitivities? Any fool can publish in journals. Its called pay to publish. Nothing to do with advancing science in many cases! Climate science is as scientific as political science or social science.

          • “So you agree that real physics textbooks do not contain the wondrous forcings or sensitivities?”

            Obviously not. I said they DID contain information about the same concepts in the 1970s. If that’s your idea of a valid inference it’s no wonder you have to resort to character assassination in lieu of argument.

            “Any fool can publish in journals.”

            Then you would seem eminently qualified. So go on and do so.

            “Climate science is as scientific as political science or social science.”

            Try telling the NAS. Or any high-school physics student. And no, I won’t take your word over theirs.

    • barry says:

      The difference is not surprising. UAH measures temperature of the loswer atmosphere about 12km in height, surface records are of a band about 2 metres above ground level. Why would these different quantities perfectly match? And the processes to dervie a global average temperature are very, very different. Even UAH and RSS (both lower trop measurements) have different methods, if mostly the same data.

      It’s not inconsistency. There is no benchmark.

      • Richard M says:

        Barry, have you ever heard of the adiabatic lapse rate? That is the physics that ties the lower Troposphere to the surface. Over an entire globe is will balance out any “inconsistency”.

        Now add in that climate models tell us this part of the atmosphere should warm first and the only consistency is your denial of science.

        Very little of what you write in reply to me has much to do with what I write. You seem to be fixated on ideas that you use other people’s comments to introduce. Have you been playing in the climate blogs again, little one?

        Nothing about the adiabatic lapse rate forces tropospheric temps to perfectly mirror surface temps. For instance, there are fewer clouds 2 meters above the surface of the Earth. The surface temps are also more affected by surface albedo than the middle of the troposphere is. Global coverage between satellite and surface is different. Even the 2 satellite data sets have slightly different coverage. The list goes on. That’s even before we get to the very different methodologies, and neither you nor I are learned enough to determine which is better. For a start, you don’t know how UAH6.0 is derived – not to any granular understanding that would give you the insight to make a call. Of course, you would need a similarly granular understanding of how the other data sets are put together in order to make a cogent comparison. “They don’t use models” is certainly not a detailed comprehension of how the data is assembled to make a global temperature average.

        People who prefer one data set over another are not at all skeptical, and the choice of UAH for AGW critics is lamely obvious.

            Strangely, the NAS – the leading scientific body of the nation – seem to agree with me that it is McIntyre and McKittrick who are walking around tackle-out. YOU might have blind faith in a pair of frauds who are trying to smear a real scientist, but the nation’s leading scientists clearly do not. And as they have just elected Dr. Mann to their number I’d say your ideological convenience can safely be ignored.

            So, again, take it up with the NAS. Or any of the dozens of teams who have used a score of lines of evidence to corroborate his work.

            Actually, that’s not a bad yardstick. Let’s see you criticise EVEN ONE of the other proxy series that independently show the hockey stick shape without mentioning Dr. Mann’s name, if you think there’s any substance to your drivel.

          • That tweet of a screenshot yields a text which can be traced to a Murdoch rag known as “The Times”, once a decent paper. The full text is behind a paywall, but the accessible portion states:

            “Britain could be at risk of blackouts as extremely low energy demand threatens to leave the electricity grid overwhelmed by surplus power.

            “National Grid asked the regulator yesterday for emergency powers to switch off solar and wind farms to prevent the grid from being swamped on the May 8 bank holiday, when demand is expected to be especially low.”

            So no, based on that source, John is not “right” in any useful sense. National Grid issued no such warning; it asked for the powers to AVERT the possibility of blackouts. Nor is the fact of excess power from renewables particularly convenient to the denialist agenda in the first place: When seeking to claim that a climate disaster cannot be imminent because the measures needed to prevent it cannot provide enough capacity to support leisure activities, the danger that those measures might flood the grid with excess power is NOT the kind of argument you need.

          • barry says:

            Pro tip, Jim. Link to the article you are pointing people to, not just the home page. The top article drops away when the next one is posted, and few people will bother to trawl the site for your reference.

            I bothered, and look what the article says:

            “National Grid asked the regulator yesterday for emergency powers to switch off solar and wind farms to prevent the grid from being swamped on the May 8 bank holiday, when demand is expected to be especially low.”

            So wind and solar might have put too much power to the grid in a low demand period.

          Right now, wind is providing 2.21% of UK demand (gasp). Not sure that fits your narrative of “reliable” power. Thank goodness we still have significant CCGT deliverability (currently 46.8% of demand).

          • Thank science it wasn’t needed for 18 days running. And that’s just the most recent, record, contiguous time-period.

            You’re already reduced to bleating about “warnings” that are, of course, not realised. (Although we had regular blackouts in my childhood when coal ruled the game, and they still happen routinely in regions threatened by natural disasters like tropical storms.) What are you going to fall back on in a few years when coal rarely needs cycling up at all?

          • “Right now, wind is providing 2.21% of UK demand (gasp).”

            Not sure where you are getting that 2.2% Jim,

            From Wiki:

            “Wind power contributed 18% of UK electricity generation in 2018, making up 52% of electricity generation from renewable sources.”

          • Jim Ross says:

            Nate,

            I was referring to actual supply at the time of my comment rather than some historical average figure. Data are shown and updated every 5 minutes here:

            http://www.gridwatch.templar.co.uk/

            Wind was very light all day yesterday (high pressure system). You can view or download the data for yesterday if you want to check. Wind is currently 8.41% of demand. Solar is predictable in timing, but not in quantity (better today than yesterday). Apart from a small amount of hydro, the only “reliable” renewable source is biomass, currently running flat out at 3GW (10.66% of demand).

          • Nate says:

            Wind does have the issue of intermittency, whereas other sources have their own issues of being polluting, costly, unsustainable, etc

            Wind intermittency is somewhat predictable, daily and seasonally, as with solar.

            Along with a smart grid, distributed diverse sources, more energy storage, I dont see this as a fundamentally insurmountable issue.

        • Nate – Far from it. It is merely the mirror of the problem of inflexibility in coal generation. One will always require technology to match supply to demand, whether one has to balance load or output. A degree of redundancy has always applied.

            I agree that it is far from fundamentally insurmountable. Just business as usual by other means.

        • We can’t know for certain, but we can measure the overall budget of incoming and outgoing radiation. When all the known influences add up to the incoming flux minus the outgoing, representing a deficit for the known forcings, you at least know that your energy budget balances. From which it follows that any unknown influences add up to zero.

            See the post that I replied to, rather than just mine in isolation. Duh.

            In fact, no-one can know anything “for certain”, EXCEPT that no-one can know anything for certain. That’s an epistemic theorem, when working within the constraints of empiricism – the only constraints that matter aside from the proofs of mathematics in any useful pursuit like science.

            I for one make an effort never to say anything beyond the limits of confidence that I can reasonably justify, so I tend to look things up or test them with a spreadsheet or whatever before offering anything as more than my own opinion. Any time you catch me exceeding that, feel free to point it out, but don’t believe for a minute that insulting Dr. Mann, talking about “the left” or any other such nonsense will suffice instead.

            I suspect that you will never find an instance where I am not quoting easily-referred science, checkable arithmetic results or the open dishonesty of a denialist interlocutor. And I guarantee I’ll correct anything that can be shown to be false, once noticed. Mostly another and more numerate poster comes along with better and more quantitative support while the deniers are still trying to work out how to introduce Galileo or Stalin into their “argument”.

    It has been suggested that I ask you how “Jupiter and Saturn cause the sun to move away”.

    Please enlighten me.

  27. When I first read of the near record-setting drop in the global anomaly for April, I thought it supported the global warmists’ argument, as less CO2 would have been spewed into the atmosphere with the COVID-19 induced recession. But then it occurred to me that the greenhouse effect was based on the TOTAL concentration of CO2 in the atmosphere, which, I assume , would not have gone down in April, what with the long-life of CO2 up there; in fact, may have increased slightly, albeit less than in normal times. If this be the case, than the dramatic drop in temperature might arise from all the other pollutants in our dirty skies decreasing. Any logic in this? (Disclaimer: I am not a scientist, though I play one in my own living room.)

    • Midas says:

      The monthly trend is only +0.001C per month.
      The detrended monthly standard deviation is 0.18C.
      So the monthly variability is 180 times the upward trend.

      Surely that is enough to tell you that you can’t attribute a single monthly change to changes in CO2 levels.

    • bdgwx says:

      Ken said: If this be the case, than the dramatic drop in temperature might arise from all the other pollutants in our dirty skies decreasing. Any logic in this?

      Aerosols produces a net negative radiative force. Less aerosols yield a net positive change in aggregate raditative force. This would put an ever so slight upward pressure on the Earth energy imbalance. But like Midas said the variation in monthly anomalies is quite high so given the short duration and small magnitude of the affect this aerosol signal would easily get lost in the noise.

      The April drop is likely to be associated with the warming stratosphere in the previous months. The leading hypothesis is that the Australian wildfires lofted anomalous aerosols into the stratosphere. Prior spikes in stratosphere temperatures have lead cooling in the troposphere. It can take a year or so for this aerosol induced warming/cooling of the stratosphere/troposphere to wane.

  28. Ercan says:

    Positive anomaly of 0.38 C seems to be lower than my expectation.
    I have expected hotter temperature as result of more solar radiation hitting on the earth, due to more clean air caused by widespread lockdown from the pandemic.

      • “Lives in Bangladesh or anywhere else in the 40%-odd of land vulnerable to desertification”. Happy?

        There is a level of annual precipitation that is conventionally regarded as the limit below which cereals will not grow. Let’s say 250mm, as I cannot scare up the correct figure at short notice. I recently saw an interesting map plotting the 250mm precipitation line on a map of Eurasia and Africa. The line follows the borders of deserts, as you would imagine.

        More interestingly, the line passes directly through almost all conflict zones in the region. Even more so, ALL US drone strikes in the region are so close to the line as to be inseparable by eye at that scale.

        So warmer is not necessarily better, at least while water and food stress remain bigger threats to human life than mountaineering.

      • Nate says:

        “Mt Everest is about 28 degrees North.” And no one lives on it.

        The point, for the perpetually perplexed, is the Earth has a Equator to pole gradient in temperature. Humans and other life-forms have adapted to a range of temperatures.

        The notion that increasing the temperature everywhere that humans live is BETTER, is a repeated meme here and makes no sense.

          “We show that for thousands of years, humans have concentrated in a surprisingly narrow subset of Earths available climates, characterized by mean annual temperatures around ∼13 C. This distribution likely reflects a human temperature niche related to fundamental constraints. We demonstrate that depending on scenarios of population growth and warming, over the coming 50 y, 1 to 3 billion people are projected to be left outside the climate conditions that have served humanity well over the past 6,000 y. Absent climate mitigation or migration, a substantial part of humanity will be exposed to mean annual temperatures warmer than nearly anywhere today.”

          They project a fair proportion of humanity enduring conditions hotter than today’s Sahara.

  34. Bindidon says:

    Robertson’s ignorance concerning anomaly-based time series and trends
    is simply horrifiying.

    Let us review his nonsense:

    How can anyone claim a 0.14C/decade linear ‘TRUE’ warming trend when 18 years was below average and another 18 years had a flat trend? What happens if the anomalies drop back to the baseline? How then will you calculate the trend?

    These trends are not calculated using a best fit of the data over the entire range since that could not be done using end points between 1979 and 2020. They are calculated using algorithms that ignore the physical contexts. They operate on the data alone without consideration of the contexts from which the data came.

    The only way a 0.14C trend could have been calculated for TRUE warming would have been a scenario in which the UAH trend began at the baseline in 1979 and continued upward till the trend line intercepted the y-axis after 40 years at 0.56C. That has not been the case.

    *
    1. My first question would be: Why doesn’t Robertson at least have the courage to seek an explicit confrontation with Roy Spencer, who precisely calculates and publishes the trend of 0.14 C / decade for his own data – what Robertson nonetheless allows himself to doubt?

    Why does he not tell Roy Spencer that his trend computation is wrong?

    *
    2. Robertson has, though having been informed by many commentators in this blog, still no knowledge about how a linear trend is calculated.

    Trends are based on ordinary least squares, and have nothing to do with any average, let alone with anomalies. They are exactly what he refuses to learn and accept: a best fit over a set of data points, e.g.

    https://drive.google.com/file/d/14alPDag5YUJkhLqJZgfQjpTId6MN__DB/view

    In this graph, only the data points are shown, and not the lines connecting them.

    What Robertson doesn’t not understand (or, maybe, deliberately ignores) is that if another period was chosen to compute the anomalies out of the absolute data (e.g. 1990-2014 instead of 1981-2010), this would result in different anomalies, but the trend computed out of the new anomaly data points would keep the same.

    This has been explained to him so many times that I suspect that he is repeating his nonsense endlessly in the hope to be considered an expert on the matter.

    *
    3. Maybe it helps if I show a reconstruction of UAH’s absolute data, together with the trend, this time computed out of the absolute data points:

    https://drive.google.com/file/d/1B2qDLO0T8ZO6IqduIdlppIoIAKSsDY7F/view

    No red baseline here, and thus no rewarming below the baseline, no TRUE warming above the baseline. Only warming.

    The trend line looks a bit flatter than in the anomaly chart, but the trends for Dec 1978 – Mar 2020 are nearly equal (0.135 C / decade for the anomalies, 0.133 C for the absolute values).

    And of course: the trend for 1998-2015 is here absolutely flat as well, he he.

    Maybe he understands now (or is willing to give up his nonsensical ideas). But maybe what he wrote will reappear unchanged at the next opportunity. So what!

    J.-P. D.

    P.S. For those who always refer to 2016 as the ‘Super El Nino year’: please notice that the highest absolute value (-7.35 C) is in July 1998, and not in 2016.

  35. Gordon Robertson says:

    svante…”He likes his PRATTs, for example that base lines are the gold standard for “true warming” (they are arbitrary)”.

    Maybe you and Gore & Co. should read what real climate scientists have to say on that. I got my information on true warming after the 1998 EN from the UAH 33 year report. Furthermore, UAH has addressed the projected situation with no aerosol cooling, claiming the trend would have been 0.09C/decade.

    The two of you need to take courses in statistics. If you have a trend below the baseline it means the anomalies are cooler than the baseline temperature. Without the aerosol cooling, the anomalies move toward the baseline making the trend lower, as claimed by UAH, not higher.

    What is it about negative anomalies you don’t understand? A trend with negative anomalies does not indicate a warming of the atmosphere it indicates a recovery from cooling. That situation prevails till you reach the baseline then true warming begins.

    UAH is perfectly right to claim a 0.014C/decade trend but they are smart enough to realize it means data beginning below the baseline and continuing through the baseline to warmer anomalies. That trend says nothing about global warming per se, it is a trend from cooler temps to warmer trends.

    • Tim Folkerts says:

      “That trend [0.014C/decade] says nothing about global warming per se, it is a trend from cooler temps to warmer trends.”

      This baffles me. A trend from cooler temps to warmer temps is pretty much the *definition* of global warming over the period being studied.

      The trend doesn’t say is *why* it warmed. Nor does the trend say what is “normal”. But it most definitely says the globe has warmed.

      It could be — as you speculate — that temperatures in the 1980’s were cool and then there was “a recovery” back toward “normal”. It might be that the globe was “normal” in the 1980’s and then crept above “normal” in the next decades. It could also be that the 1980’s were already above “normal”, but temperatures rose even farther from there.

      * ALL OF THESE would produce exactly the same graph in the top post.
      * ALL OF THESE would start below the baseline and move above the baseline.

      ——————————-

      “Furthermore, UAH has addressed the projected situation with no aerosol cooling, claiming the trend would have been 0.09C/decade.”
      I have not read this report, but your description here does sound reasonable. *IF* the 1980’s were cooled an exceptionally large amount by aerosols (from pollution or volcanoes or any other source), then if we could somehow do a controlled experiment without those aerosols, the temperatures would be higher in the 1980s and the data would be higher (closer to the baseline). This would cause a decrease in the trend observed.

      (Of course, that would also INCREASE the trend leading up to the 1980’s.)

  36. Gordon Robertson says:

    Richard M…”Surface data sets are very poor and are not based on anything closely approaching science”.

    The guy at chiefio exposed the fudging that goes on with surface temps. I mentioned how Bolivia has altitudes of over 15,000 feet, which would mean cooler temps. NOAA no longer lists Bolivia, rather they have fudged a temperature for Bolivia using an interpolation of areas around Bolivia at much lower temps.

    You provide a link to a paper by the Mother of all Alarmists, Gavin Schmidt, head of NASA GISS. Schmidt is a mathematician who programs models with a warming positive feedback and CO2 with a fudged warming factor of 9% – 25%. In an attempt to explain positive feedback he failed to do it.

    At the link below, scroll half the way down the page to the title ‘Gavin Schmidt on Positive Feedback’.

    http://rocketscientistsjournal.com/2006/11/gavin_schmidt_on_the_acquittal.html

    He runs realclimate, the Mother of ALL Alarmist Sites, with his good buddy Michael Mann, who was noted in the Climategate email scandal as the author of ‘the trick’, a scam invented by Mann to hide declining temperatures. The Climategate emails reveal him vigorously trying to interfere with peer review. Meanwhile, back on the ranch at realclimate, Schmidt, the head of GISS, covered for him with lame excuses for why Mann was acting like an alarmist climate hooligan.

    You won’t find any objective scientific evidence in an article by Schmidt that the satellite data is corroborating the fudged surface series, with GISS as one of the leading fudgers under Schmidt.

Mann is not worthy of being the janitor at NAS.

          And I am not as stupid as those in the IPCC who rushed to embrace a study lead by a first year Ph.D, in geology of all sciences. There are smart geologists but the field tends to attract students looking for an easy degree.

      Elliott, please stop trolling.

  39. Gordon Robertson says:

    Robert Ingersoll…”Very sciency with intercept the y-axis, but seems confused on which axis that is”.

    You are the one who is confused. A trend line over a range between a beginning y-axis and and ending y-axis could only intercept the y-axis. an intercept at the x-axis would make no sense.

    You completely missed the point I was trying to make. If the UAH data over the range from 1979 can be expressed as a linear trend line of 0.14C/decade, it means the data points between 1979 and 2020 are being expressed as a straight line. I was trying to show the difference between a line extending from the x-axis at (1979,0) to a right-axis at (2020,5.6) which would have represented true warming.

    However, the data begins below the x-axis which on the UAH graph is called the baseline, representing the global average from 1980 – 2010. It’s amazing how many wannabee statisticians on this blog fail to grasp that. The x-axis is that global average. Any anomalies below the baseline represent temperatures below the average.

    The trend as a line is a function of x (y = f(x)). That means for each point on the x-axis there is a unique point on the y-axis corresponding to the x-point. The line is described by y = mx + b, where m is the slope of the line (change in y versus change in x) and b is the y-intercept. That intercept applies at x = 0 if the line passes through the y-axis at a point other than (0,0).

    However, with a trend line, with the line extending through a range, as in the UAH graph from 1979 – 2020, you are concerned with where it intercepts both the left and right axes at either end of the range. I was referring to the left-most coordinate as (1979,0) and the right-most coordinate as (2020,5.6), or whatever value I used. I was using 5.6C as the right-most y-intercept based on 0.14C/decade x 4 decades.

    There is no way a trend expressed as so many degrees /decade could be anything other than a straight line. Such a trend line is trying to make a best fit of a straight line through data points. On the other hand, Roy has kindly supplied a different type statistic called a running average, which smooths out the erratic data point anomalies and gives as a better picture of the trend.

    Using that red curve, the running average, you can average the trend visually in a rough manner and see that several trends are apparent in the data. There is a rewarming trend from 1979 – 1998, a flat trend from 1998 – 2015, then two trends, at least from 2015 onward.

    It’s obvious there has been a warming since 1979 but what does it mean? Many alarmists are claiming it as proof of CO2 warming yet how could CO2 cause an 18 year flat trend? Many of us see it as a natural cyclical trend that should eventually come back down to the baseline or below.

  40. Gordon Robertson says:

    swannie…”The fact that there are more data points below the average in the beginning of the record and more above later just tells anyone whos listening that there warming going on. The trend calculation does not rely on the baseline in regard and the trend is the important variable, not this months particular value above (or below) the baseline.

    Moron.”

    You, of all people, should not be calling anyone a moron after your amazingly ignorant conclusions from experiments alleging the 2nd law of thermodynamics is wrong. It was blatantly obvious to anyone with a basic understanding of thermodynamics that you were mistaking a reverse transfer of heat (cold to hot), contradicting the 2nd law, with a reduced heat dissipation in a body causing that body to warm naturally toward its temperature with no dissipation.

    With regard to your analysis of trends and baseline, they are just about equally ignorant. Since the baseline is also the x axis at y=0, the slope of the trend line has everything to do with the baseline. The anomalies are the departure from the baseline in the +/- y direction.

    The trend ‘line’ is a function of x as in y = f(x). In this case x is a measure of time (months/years) and y is a measure of temperature. That is reflected in the measure of the trend line in degrees C/decade. Having established the baseline at y = 0 as the global average from 1981 – 2010, each anomaly is the departure from that average each month.

    It’s painfully obvious that a positive trend line below y = 0, the global average, represents a recovery from cooling. As UAH have pointed out in the 33 year report, a trend line above the baseline is ‘TRUE’ warming.

    Having established that, the true warming rose about 0.15C from 2000 – 2001 then the trend flattened for 15 years at that level. It was not till mid-2015 that the trend began to rise again, in conjunction with a major El Nino in early 2016. Then it became negative till mid-2018 when it became positive again.

    It’s not possible based on the shortness of the UAH record to make claims about an overall global warming. Neither is it possible to get the degree of warming from the NOAA and Gistemp records since they are seriously fudged by climate alarmists.

    As it stands, about all we can agree upon is that warming has occurred since the Little Ice Age that ended circa 1850. That warming is to be expected.

    • E. Swanson says:

      Gordo, you have no clue what the “base line” you refer to means. As you view the UAH graph at the top of this post, what you are seeing is the result of an an averaging process. Once the “raw” gridded data, in Kelvin, is processed, it is reduced to monthly zonally averaged data with averaging over some selected base period. But, to compare different latitudes and seasons, the seasonal cycle for each latitude zone is calculated and then subtracted from the monthly data for each year. The resulting anomalies can then be averaged over some range of latitude, such as the UAH 20S to 20N as Tropics or the 60N to 82.5N region called Arctic, averaged by weighting with the cosine of latitude to account for the reduction in area of each zone as latitude increases.

      The resulting data sets, such as the MT or the TP, will exhibit a range of values on a scatter plot, with the center of the distribution being around the zero line of the graph. A trend line can then be calculated to fit the resulting data.

      And, no, the GPE does not violate the 2nd Law and there’s no such thing as a “natural temperature” of a body as you allude to above.

      • Gordon Robertson says:

        swannie…”you have no clue what the base line you refer to means”.

        As it states on the y-axis of the UAH graph, the baseline is the global average from 1981 – 2010. What is it about the simple definition you don’t understand? The anomalies are described as the ‘departure’ from that average.

        And, yes, every body has a natural temperature when dissipation is total stopped. If you consider the 2N3055 power transistor it will reach a certain junction temperature at 25C ambient conditions. It will maintain a safe junction temperature as long as you allow as much heat to escape as what is introduced by the junction current. Heat in – heat out is the key.

        If you suppress all dissipation, its temperature will rise to the temperature produced by electrons running through the semiconductor junction. If the temperature is too high, it will cause thermal runaway and the transistor will burn up. So, we need to find a current it can sustain just before thermal runaway.

        I call that temperature its natural temperature ‘with all dissipation suppressed’. Once you supply a means of radiative dissipation, conductive and convective dissipation, the temperature would drop to a certain temperature which it would maintain under those conditions of dissipation. If you come along and block any one of those means of dissipation the temperature will increase toward the natural temperature I described.

        That’s what happened in your experiment. The BP had established a temperature with the amount of free radiation it had balancing the heat input. When you raised the GP right in front of it, you blocked that free radiation and the BP reacted by warming. It had nothing to do with back radiation from the colder GP as you claimed, the temperature rise was due only to the effect of the heating supplied.

  41. Gordon Robertson says:

    gore & co…”looking doesnt replace calculating”

    Funny, they encouraged us to do that in engineering before we rushed to calculations. In fact, we were trained to do things by inspection in problem sets before rushing to an answer.

    You can learn a good deal about what a problem or question is asking by looking at, or creating a simple graph. I agree that calculations are more accurate but there are cases when a visual inspection is so good that working out the details is not that helpful. Furthermore, working purely on a calculator or Excel program can be seriously misleading.

    In Engineering, we were taught to confirm answers worked out on calculators by simplified methods. If you look at the real contexts in the UAh graph, a trend of 0.14C/decade is not very helpful. In fact, it is misleading. It does not describe the data accurately and leads alarmists to conclude the trend is due to CO2 warming.

    If you LOOK at the graph with scrutiny, it becomes apparent that CO2 could never produce the different contexts that are obvious. Roy claims he thinks CO2 may be partially responsible but he does not say how much. He also claims that natural variability is likely.

    I have also noted how flustered you get when you are caught in an error. You did the same when I posted proof that the IPCC admitted to a flat trend from 1998 – 2012 and that NOAA admitted to slashing it’s surface stations from 6000 to less than 1500.

    • barry says:

      Robertson,

      The first graph has a URL, which you can read and see where it comes from, the same way you can see that the second graph I linkes is from Roy Spencer. Quit being dense.

      I haven’t got caught out in a error, you nitwit. The TLT channel (originally channel 2, now channel 5) measures a deep swathe of the atmosphere weighted most strongly at about 3 kilometers. That isd what I said, and exactly what Roy’s graph shows you.

      Did you know that MSU channels 1, 2, and 15 are considered “window” channels because the atmosphere is essentially clear of microwave radiance at those frequencies, so virtually all of the measured microwave radiation comes from the surface. While this sounds like a good way to measure surface temperature, it turns out that the microwave emissivity of the surface (it’s ability to emit microwave energy) is so variable that it is difficult to accurately measure surface temperatures using these measurements. The variable emissivity problem is the smallest for well-vegetated surfaces, and largest for snow-covered surfaces. While the microwave emissivity of the ocean surfaces around 50 GHz is more stable, it just happens to have a temperature dependence which almost exactly cancels out any sensitivity to surface temperature.

      So no, UAH on-board instruments cannot separate ground from atmospheric radiance. In fact, there is some stratospheric influence in the product UAH call Temperature Lowere Troposphere. There is also ground influence, but it is impossible to extract the temperature of these thinner layers from the 12km swathe UAH TLT is measuring.

  43. Gordon Robertson says:

    barry…”I dont think UAH is the best. They are all estimates with strengths and weaknesses ”

    Are you sure Bindidon has not taken over your nym? I don’t recall you being quite this stupid.

    An AMSU unit on a NOAA satellite is a sophisticated electronic device flown originally to get date for weather forecasting. It does not ‘estimate’ it measures directly the microwave emissions from oxygen molecules. Like any instrument measuring a broad range of frequencies it averages the emissions received. However, the frequency spectrum is broken down into channels that can measure frequencies pertinent to the lower atmosphere.

    Claiming the measurements are estimates is based on ignorance of the pressure/temperature relationship in the lower atmosphere which is linear. It’s a far better system than thermometers in boxes at fixed heights in the atmosphere spread out over distance of a 1000 miles. Even Hansen admitted to the problems there.

    When NOAA begins artificially estimating temperatures based on an interpolation and homogenization of temperatures from stations up to 1200 miles apart, using a climate model, then you have fudged temperatures. That’s over the land surfaces not the oceans, which are completely fudged due to the impossibility of getting thermometers to cover them.

    • barry says:

      You supreme ignorance on this is boundless, and in the face of many source material being made available to you to learn better, endless.

      Of course the temperature measurements are estimates. There are numerous instruments over time, decay of orbit of the satellites over time and intercallibration between different sensors and satellites is not perfect as Dr Spencer has said himself.

      Further, the satellites do not read the entire Earth in one go. They take a few days to scan the globe, so you do not have real-time complete coverage.

      It is fascinating that it makes no impression on you that the UAH TLT product has been through many versions and the trends from those data have changed, sometimes dramatically, with every revision.

      If the AMSU data is perfect, why do revisions keep happening?

      You’re just brainless, mate.

      • Gordon Robertson says:

        barry…”Of course the temperature measurements are estimates”.

        There is a difference between estimates and error margins. Everything in good science is stated with an error margin. UAH claimed that the orbital issue in the Tropics produced an error that fell within the stated error margin.

        In electronics, resistors are stated with a tolerance. You never expect a 10K resistor to measure exactly 10,000 ohms on a DVM. Tolerances are built into scientific measurement as error margins. We had that drummed into us in first year science labs.

        UAH has claimed to have compared it’s temperature measurements with radiosondes and found them to compare favourably.

      • barry says:

        And so does RSS. It depends on which radiosonde data you use.

    John Garrett…”Piltdown Mann was either hopelessly incompetent or a fraud”.

    It was the former, he had just received his Ph.D (in geology) a year before publishing the paper. He was still green around the ears yet he got published and the IPCC and Al Gore rushed to endorse his madness.

    Although Mann’s paper ignored the Medieval Warming Period and the Little Ice Age (they wanted a flat shaft for the hockey stick), the IPCC should have caught that because in the 1990 review they published a graph acknowledging the MWP and LIA.

    The IPCC soon distanced itself from the hockey stick, re-issuing it with so many error bars it became known as the spaghetti graph. It also re-instituted the MWP and the LIA so the shaft looks nothing like a straight shaft. Whereas Mann had claimed 1000 years, the IPCC changed that to 1850 onward.

    The IPCC is loaded with climate alarmists. Phil Jones of Had-crut and Kevin Trenberth of NCAR, were partners as Coordinating Lead Authors at IPCC reviews. CLAs select the Lead Authors, who are politically selected, and the LAs select the reviewers.

    All in all, the process stinks. After the reviews are submitted by 2500 reviewers, the IPCC allows the Summary for Policymakers, written by 50 lead authors to override the reviews. They amend the reviews by 2500 reviewers so it is in line with the Summary.

    In the Climategate email scandal, Jones is quoted as claiming he and ‘Kevin’ will make sure that certain skeptical papers don’t make it into the IPCC review stage. I am sure one of those papers was co-authored by John Christy of UAH.

    The IPCC, and now NAS, has been infiltrated by alarmist scumbags. Anyone who claims the hockey stick is legit, is not only delusional, he/she is an idiot.

    • “The IPCC, and now NAS, has been infiltrated by alarmist scumbags.”

      “Anyone who claims the hockey stick is legit, is not only delusional, he/she is an idiot.”

      Arf. Anyone claiming to have successfully reconstructed historical temperatures without finding a hockey stick is a liar. What your kind can never grasp is that science ultimately rests on INDEPENDENT REPLICATION. Being ideologues you think that discrediting the original witness will make reality go away, but the witness could turn out to be Hitler, Jack the Ripper, Dracula, Yosemite Sam and Donald Trump all rolled into one and that would not make it go dark inside when they say it is daytime.

      We agree that it is daytime because everyone looks out the window and sees that the Sun is out. Smearing the first person to notice only works in politics.

      • Gordon Robertson says:

        Elliott…”What your kind can never grasp is that science ultimately rests on INDEPENDENT REPLICATION”.

        Yes…it’s called the scientific method. How could anyone possibly duplicate the trash science in the hockey stick pseudo-science? Two of the first claiming to do it were…tada…students of Mann.

        When McIntyre and McKitrick analyzed the work of Mann et al, they found that white noise would produce a hockey stick using the Mann et al algorithms. When statistics expert Wegmann analyzed it he agreed, and added that section 9 of the IPCC reviews were all buddies of Mann who nepotically cited only the works of each other.

        After the misogynist behaviour of Mann toward scholar Judith Curry, who is at least twice the scientist Mann ever thought of being, and his despicable behavior revealed in the Climategate email scandal, why would NAS possibly induct him? The only possible answer is that NAS is now run by climate alarmist weenies.

        • Gordon Robertson says:

          I omitted to clarify the section 9 incident. When M&M complained to the IPCC about the hockey stick they were initially rebuffed by IPCC bigwig Susan Solomon. She finally acquiesced and appointed section 9 to investigate. They completely ignored her, leading Wegmann to investigate as to why. That’s when he found section 9 and Mann were buddies who cited only the work of each other.

          Wegmann referred to section 9 as nepotic. The only retort from Mann et al was to charge Wegmann with plagiarism. Excuse me??? An investigator quotes from the works of one of the co-authors in MBB98, and he is charged with plagiarism??? The weenies in MBB were too stupid to understand the meaning of plagiarism.

        • “Yesits called the scientific method. How could anyone possibly duplicate the trash science in the hockey stick pseudo-science?”

          No-one, basically. Everyone who has constructed a corroborating series has found the same shape.

          “When McIntyre and McKitrick analyzed the work of Mann et al”

          I.e. did not attempt their own replication.

          “they found that white noise would produce a hockey stick using the Mann et al algorithms.”

          When you use epicycles as they were calculated at the time of Kepler, you can produce the movement of the planets BETTER than using the maths of heliocentrism as it was used at the same time. Heliocentrism remains correct, nevertheless. It is only in the delusional world of deniers that a correct result with an irrelevent methodological flaw remains incorrect for all time, no matter how often it is reproduced with corrected methods.

          The hockey stick remains no matter who reconstructs it, no matter how carefully the method is corrected. It’s real. None of you will ever produce a conflicting result. In fact, as your perpetual, desperate resort to McI and McK demonstrates, you cannot even imagine what a conflicting result would look like. You are citing an alleged demonstration that the result would appear even if not real instead of a demonstration that it does not appear when properly checked and YOU DON’T EVEN UNDERSTAND THE DIFFERENCE.

          Now that’s pitiful.

          “When statistics expert Wegmann analyzed it he agreed, and added that section 9 of the IPCC reviews were all buddies of Mann who nepotically cited only the works of each other.”

          See above. Not one person can show that the hockey stick is not there when methodological flaws are later corrected. Not one person can produce a conflicting result. Dozens of teams independently reproduce the same phenomenon. It’s real.

          “After the misogynist behaviour of Mann toward scholar Judith Curry, who is at least twice the scientist Mann ever thought of being, and his despicable behavior revealed in the Climategate email scandal, why would NAS possibly induct him?”

          Because he’s a scientist of NAS-level standing and importance, and because the NAS is more interested in that fact than in your attempt to smear him with irrelevances and name-calling.

          Anyway, if you still believe in the climategate “scandal” you are a couple of perverts short of a conservative club.

          • Ball4 says:

            “Dozens of teams independently reproduce the same phenomenon. It’s real.”

            Every one of those teams used enough of the same known to be HS proxies a priori eliminating the proxies that do not show enough HS for their particular taste. If not, then post up a published study that does no a priori proxy selection & properly uses all the available proxies in the field exactly as published by the original author.

          • Post ANY published temperature reconstruction that fails to confirm Mann et al’s original finding. I have issued this challenge repeatedly and never been answered. Instead of responding you move the goalposts by inserting a manifestly unsatisfiable condition based on an unfounded allegation of “taste”.

            All published reconstructions using proxies have by definition satisfied the preconditions of sufficient quality for publication, the only conditions that interest anyone. Trying to filter out the entire body of research with deranged fantasies about “taste” does not dismiss the clear inference that you have no papers at all with which to falsify the Hockey Stick. It reinforces that inference.

            Can you even name a proxy where the “original author” is not also party to the temperature reconstruction? I’d be surprised if you ever even bothered to cross-check.

            Global multiproxy database here: https://www.nature.com/articles/sdata201788 It’s quite big.

          • Ball4 says:

            “Can you even name a proxy where the “original author” is not also party to the temperature reconstruction?”

            Tiljander.

            I observe Elliot was unable to post up any paleo temperature reconstructions without a priori selection to limit proxies to those containing the signals selected by the researchers.

            Confirming, so far, my position there is no relevant paper that uses ALL the proper proxies in the field, the quite big “Global multiproxy database” which doesn’t contain unpublished data used in some reconstructions so the work cannot be replicated.

          • “Tiljander.”

            Fair enough. Mann used that one as part of an aggregate study of many proxies, so it is not unexpected that he would not have prodiced them all personally. Hardly supports anything else you say, though, does it?

            “I observe Elliot was unable to post up any paleo temperature reconstructions without a priori selection to limit proxies to those containing the signals selected by the researchers”

            I don’t have to. It’s quite obviously an illegitimate demand and intended only as a crude attempt to distract from your lack of any supporting research. Any study is clearly going to select and/or normalise data according to quality criteria fitting the study. Since that leaves it open for you to keep parroting unsubstantiated claims that the selection was done just to bias the outcome, there is no legitimate need to answer.

            The fact that none of you can come up with a study of your own that falsifies Mann et al is the only criterion that need be considered, as it is the only SCIENTIFIC basis on which dozens of replications could possibly be overturned.

            Any of you could go through that database or collect your own proxy data and show the outcome when it is properly analysed. But you’re not going to do that, because you know just as well as the rest of us that the Hockey Stick will just end up getting yet another replication if you try. So we just get empty bluster.

          • Ball4 says:

            “Hardly supports anything else you say, though, does it?”

            Not intended. Only an answer to the focused question you asked.

            “I don’t have to.”

            Then your claim the HS always results when a priori proxy selection “fitting the study” is not employed is in no way credible.

            Elliot, you really do have to come up with a published study not using a priori proxy selection showing a HS since they all use proxy pre-selection before going into the meat grinder in this peculiar specialist field. Quality control is entirely different.

            Come on Elliot, do the work, back up your claim “The hockey stick remains no matter who reconstructs it” without your “fitting the study”, you won’t be able to do so since it always..ALWAYS matters to a priori select proxies in this field to result in a HS.

            If you could do so easily, you already would have posted up the paper not using a priori proxy selection contrary to my claim they all do so. I don’t claim to have seen every relevant paper (as is implicit in your claim that you have) thus you might actually find one. Would be interesting.

          • Ball4 says:

            Nate, clearly a great deal of analysis* could be done answering your questions. Generating hockey sticks has become a cottage industry. My view was formed from reading up on the subject. All you need to do is find one relevant paleotemperature reconstruction paper with no smoothing & no elimination of temperature proxy for any reason to defeat my claim. I’ve never found one but plenty could be out there as I haven’t looked in a while.

            It’s the same argument on temperature series trends ad inifinitum around here, a real time waster, better things to do and life is short.

And if for some bizarre reason you do smooth it, you absolutely on pain of death do NOT use the smoothed series as input for other analyses!…This is because smoothing induces spurious signals.. ”

            Briggs also likes McShane and Wyner, see at the bottom where a straight yellow climate line fits the real data just as well as the Gordie Howe weather stick. The straight yellow line cannot be “rejected with any great certainty” over the last 1000 years.

          • “Elliot, you really do have to come up with a published study not using a priori proxy selection showing a HS since they all use proxy pre-selection before going into the meat grinder in this peculiar specialist field.”

            No. I don’t. Theory predicts the hockey stick. Every study reproduces the hockey stick. You cannot show a single properly-conducted temperature series for the period that does not show the hockey stick. NOT ONE, nota bene; sampling errors and uncertainties alone should generate one spurious negative result per 20 at the conventional 2-sigma confidence rate, so the overall confidence taken in aggregate is much, much higher.

            There is not a single legitimate criticism you can raise that addresses the entire range of proxies, and not a single line of evidence that supports your claim. Worse, not a single properly-conducted study WITHIN a single line of evidence, which chance alone should have coughed up by now if there were any real uncertainty.

            That’s why you’re essentially reduced to claiming that you can ignore scores of studies purely on the basis that you cannot understand the basis for selecting data streams. A selection without which, ironically, probably no study would be fit for publication.

            But you keep on with your “I don’t know, therefore God” line. Or global conspiracy, in this case. No-one will ever notice that you have no evidence. Arf.

            BTW, did I mention that Doctor Mann was just elected to the NAS?

          • Ball4 says:

            “Every study reproduces the hockey stick.”

            Of course Elliot, as I keep pointing out, since “every study” a priori selects certain temperature proxies that are known to have a strong enough HS shape & deselect proxies that don’t show a HS (blade up) in this peculiar field. As I wrote, I am aware of no study that avoids the pre-selection process & uses all the proxies in the database, generally accepted applied statistical skill, and with decent quality control. Same as Elliot because none are available, Elliot just runs in place avoiding working the issue.

            Science is not conducted based on votes in elections Elliot. Funding science IS based on votes in elections though so researchers in this field react to prevailing economic incentive.

            1. He claims that, but doesnt show that it is the case. Drawing a line is not sufficient.

            2. A straight line clearly doesnt fit the instrumental record.

          • Ball4 says:

            The straight yellow line and the real unsmoothed temperature data (which has measurement error) are both 95% significant as all their respective points are within the CIs. Nature’s actual precise data, if known, could even be outside those CIs (the other 5%).

            The HS is just as significant as a straight line but HS papers get way more funding than straight lines like the black line in top post. It’s just the way the world works.

          • Nate says:

            “all their respective points are within the CIs.’

            That’s now how curve fitting works, Ball4.

            For example, I could draw a curve that is always on the bottom end of the 2 sigma CI, but that would be a terrible fit and have low significance.

            If we look at a temperature record sampled monthly, instead of yearly, we will get more noise and larger CI, and according to your logic, a wider variety of curves could then fit the data.

            If we sample weekly, or daily, even worse.

            And that makes no sense.

          • Ball4 says:

            Nate, the significance doesn’t change as you write. A hockey stick, a straight constant line, a descending or ascending line from left to right all fit the MW Fig. 16 with 95% confidence that nature does too. Take your pick with equal 95% confidence become a fan of 1000 year climate HS, straight constant line or hey climate is getting warmer/cooler ascending/descending line – all of those various fan boys are on this blog. You know who you are.

            Stat.s provides us the 95% confidence that the real no error natural temperature anomaly is in there somewhere but it is unknown where in MW Fig. 16. No one can prove any fan boy right or wrong based on last 1000 years of temperature proxy/instruments.

            The point of all this is the proxies used in Mann et. al. 08 (or 98,99) do statistically little better at explaining the temperature trends than random noise. You can be a 95% confident HS devotee, coolista, warmista or lukewarmer and feel comfortable with 95% confidence that you cannot be proved wrong….or right.

        • Ball4 says:

          Always been available? No that’s not quite fact, there was no contemporaneous archiving of the MBH98 code causing quite a subsequent commotion.

          Note the dates in the file structure you link. The archiving is many years after the paper (~July 2005). Inspection of the source code you link requires source input files not at the existing archive. The code is not operational with only your link; perhaps you can find the input files later posted somewhere else if you want to stick to your point.

        • bdgwx says:

          Fair point on “always”. I should have said at least at the time of the Wegman request. Wegman seemed to be satisfied (or least not dissatisfied) with the delivered materials at least in regards to what was delivered. However, Wegman did express concern that it was “not organized or documented in such a way that makes it practical for an outsider to replicate” and that “the directory and file structure Dr. Mann used are embedded in the code”. He did not express concern with anything being missing from what I read. I wonder if the “several websites” that were given to Wegman included datasets used by MBH, but not owned or maintained by MBH.

          This does bring up an interesting issue. If public funds are used to provide products that require non-public datasets how does that get handled? Should it be a law that private entities or otherwise non-affiliated entities forfeit their IP rights if their products are used for publicly funded research? I don’t have an answer for that. Just throwing it out as a talking point.

          • Ball4 says:

            Your Wegman clips seem to indicate he (or associates) didn’t try to replicate so, standing alone, indicates him being unaware of jneeded detail files missing from the archive. It’s been a long while since MBH98,99,08 was all litigated. I don’t recall any overall major improvement archiving published paper SI in this field though there has been limited movement in a better direction allowing replication here and there.

            Society still looking for your better answers; survival of the fittest will be at play for a long time sorting out imo. There exists a complicated competition for limited funds, to publish preserving IP rights, journal compensation, public rights to the information, & much more which all compete. What you see out there is the current wild west compromise of academic capitalism & its required regulation with the rise of blogs, vlogs, tweets, FB, and of course, above and below the decency line, age old politics in public policy.

    Now, according to myopic Barry, NAS is a zombie. NAS held a review of the paper and concluded it did not apply before 1600. The IPCC raised that to 1850. NAS told Mann et al they could not use pine bristlecone as a proxy for the 20th century, essentially negating the blade of the stick.

    That was a NAS review infiltrated by climate alarmists who did not want to put Mann down too heavily. There was a time when an idiot like a climate alarmist would never get into NAS but one or two conned their way in and now NAS is long forgotten as a hallmrk of scientific endeavour.

    Did you miss all that Barry? Or does your selective mind automatically filter it out? You are still in denial that the IPCC confirmed a flat trend from 1998 – 2012 and you can’t come to grips with a direct admission from NOAA that they slashed REPORTING global surface stations from 6000 to less than 1500.

    Bindidon cannot understand the difference between a reporting station, that is, a station from which its data is actually used, and a surface station that simply records temperatures for no apparent reason.

    binny…”My first question would be: Why doesnt Robertson at least have the courage to seek an explicit confrontation with Roy Spencer, who precisely calculates and publishes the trend of 0.14 C / decade for his own data what Robertson nonetheless allows himself to doubt?

    Why does he not tell Roy Spencer that his trend computation is wrong?”

    I have never claimed Roy’s computations are wrong. I think they are correct for a trend line from 1979 – 2020. I am questioning the meaning of the trend and UAH is a lot smarter than you at interpreting it.

    From the 33 year report:

    “While Earths climate has warmed in the last 33 years, the climb has been irregular. There was little or no warming for the first 19 years of satellite data. Clear net warming did not occur until the El Nio Pacific Ocean warming event of the century in late 1997. Since that upward jump, there has been little or no additional warming”.

    ****

    “Christy and other UAHuntsville scientists have calculated the cooling effect caused by the eruptions of Mexicos El Chichon volcano in 1982 and the Mt. Pinatubo volcano in the Philippines in 1991. When that cooling is subtracted, the long-term warming effect is reduced to 0.09 C (0.16 F) per decade, well below computer model estimates of how much global warming should have occurred”.

    Even though Roy’s trend is indicated clearly, the subjective description describes periods of cooling and a long flat trend. Roy is not stupid, like you and other alarmists, he works within the bounds of science and he knows a trend is a trend. He does not agree with you on what the trend means.

    • I’m afraid you are not in a position to speak about what a trend “means” [sic] when you cannot even maintain a consistent position on whether a warming [trend] can even be said to exist over the period in question, or subsets thereof. As long as you are flailing about and asserting that UAH (1979-2020) is too short to make claims about warming, but 1997-2020 is long enough to make them, the unfortunate impression of intellectual incontinence will persist. Possibly exacerbated by dysentery and a few curries.

      Trends don’t “mean” anything, by the way. They are quantitative and numeric, not semantic. In science, their role is to inform, confirm or disconfirm theory.

  47. Gordon Robertson says:

    binny…”2. Robertson has, though having been informed by many commentators in this blog, still no knowledge about how a linear trend is calculated.

    Trends are based on ordinary least squares, and have nothing to do with any average, let alone with anomalies. They are exactly what he refuses to learn and accept: a best fit over a set of data points, e.g. ”

    *********

    Please allow me to edumacate you on some basic statistics. The linear trend line began as a visual guess of the average value between data points on a graph. You could eyeball the data and draw a line that you thought best-fit the data.

    That trend line is a model, it’s an estimate of the actual average. The trick is to find the error between that estimate per data point and the actual value.

    It’s all based on the definition of a line, where y = mx +b. If you have a point at x = 4 and y = 8 the equation becomes:

    8 = 4m1 + b1

    If you have another point nearby at (3,7) you have:

    7 = 3m2 + b2

    In other words a line in the first case would have slope m1 and intercept the y-axis at b1, and the in the 2nd case the slope of the line would be m2 with a y-intercept of b2.

    Obviously these lines are not parallel and you want one line through many data points that has the same slope m and intercepts y at b. The line is a model and you want it to reflect the AVERAGE represented by the line.

    An anomaly is the same thing as the y-variable in the line above. It needs the x-coordinate to establish time, in case of the UAH graph, but the y variable is the actual deviation from a monthly temperature from the x-axis.

    This becomes a problem with simultaneous equations of the form y = mx + b. There is obviously an error between the real data point and the point represented by the line, a quantity called a residual. The idea is to make the sum of the squares of each residual as small as possible.

    The value you want as a residual for example 1 above is to convert it to the form:

    8 = 3m2 +b1 to the form:

    [8 – 3m2 +b1]^2 where you are squaring the difference between the real point 8 minus the modelled point 3m2 + b1.

    If you do that with a whole bunch of points, you can find the minimum using calculus and find the error in your modelled line. Least squares is a reference to a point of residual minima using a derivative in calculus.

    That does not get around the obvious, that the trend is a straight line calculated from a guess then refined to determine the error between the modelled line and the real data. You can still do that by hand using the methodology I have described.

    If you use a calculator or an Excel function, you miss all of that. The danger there is in missing what the data is trying to tell you. That’s why I refer to those using calculators or Excel without understanding the data, as bean-counters.

    • Gordon Robertson says:

      binny…”No red baseline here, and thus no rewarming below the baseline, no TRUE warming above the baseline. Only warming”.

      That’s because you have no baseline, the baseline obviously being 0C. With absolute temperatures you don’t need a baseline, it’s only with anomalies that the baseline is required.

      Here’s a real view of an absolute temperature scale. Look at figure 5 and see how insignificant global warming is on an absolute scale.

      • E. Swanson says:

        Gordo presents another denialist blast, as if those of us who have studied paleoclimate aren’t aware that the Earth has been in Ice Age conditions beginning around 3.3 million years BP. The author of your link insists on presenting the greatest temperature range from the Vostok core, comparing that range with just the past 40 years, ignoring the fact that polar temperatures exhibit an amplified temperature cycle not seen in global average data. The global average difference over the period of the Voseok core appears to be about 5 C colder.

        Of course, Gordo can’t understand that averaging absolute temperatures will be meaningless, given the wide range of in those values due to seasonal and latitude, as well as the need to area weight the data.

        We also find a plot from Loehle 2007, a completely botched report which had to be “corrected” immediately after it was published. The corrected version, published only a few months later, wasn’t a correction, but an entirely different approach which was not much better than the first, as I pointed out in a Letter to the Editor published in E&E.

    • Tim Folkerts says:

      “Obviously these lines are not parallel “
      The slopes and intercepts in your examples are arbitrary. If I make the fairly obvious choice m1 = m2 = 1 and b1 = b2 = 4, then not only are the lines parallel, the lines are identical!
      Or m1 = m2 = 0 and b1 = 8, b2 = 7. Again, the lines are parallel, but no longer identical.

      “The value you want as a residual for example 1 above is to convert it to the form:

      8 = 3m2 +b1 to the form:
      [8 – 3m2 +b1]^2”

      Your subscripts are jumbled. Did you mean m1 rather than m2? In any case, that is NOT what you want. You want a single m & b for all of the points, not separate m1,m2,m3, etc for each point.

      Lets build on your example, using 4 points, to actually understand.
      x, y
      3, 7
      3, 8
      4, 8
      4, 9

      The least square fit line is y = 1x + 4.5.

      “An anomaly is the same thing as the y-variable in the line above. ”
      No.
      * The y-variable in the line above is just the modeled fit. (7.5 @ x = 3 and 8.5 @ x = 4)
      * The RESIDUALS are -0.5, 0.5, -0.5, 0.5 respectively.
      * An anomaly is a difference from a baseline. In this case the standard baseline would be the average of all the y values = 8. The anomalies are -1, 0, 0, +1 respectively.

      Note that I could choose a different baseline — the baseline is a convenience, not something forced on us by statistics. A different baseline would change the anomalies, but would not change the slope of the line nor the residuals.

    • When I learnt the least squares method, Reagan and Thatcher were still in their first terms! Couldn’t explain it today without looking it up first to be on the safe side, of course. Google docs or LibreOffice do it just fine for everyday purposes, and Python has endless libraries for that kind of thing.

    • barry says:

      Let me try – an ordinary least squares linear regression is a claculation that derives a straight line through data points such that the sum of the squared distance between every data point and the line – is least.

      We use squared values (distance squared) – because we get all positive residuals that can’t be summed any which way to hell to get a small error – just summing the distance (not squared) would give you infinite different lines that would all sum to a zero error.

      Ordinary least squares gives a single result for the mean trend. And then you have to take uncertainty into account.

      The function of a linear trend is limited, but its ubiquity in science is because it is a powerful filter to determine some basic things, such as “has there been any change?”

    Upthread I discover a new prose from Robertson in which he replied to Svante:

    What is it about negative anomalies you don’t understand? A trend with negative anomalies does not indicate a warming of the atmosphere: it indicates a recovery from cooling. That situation prevails till you reach the baseline then true warming begins.

    This is so dumb, so stubborn, so brazen, that it becomes delightful.

    But… many people read this blog’s threads, and read the comments around them as well.

    If you don’t contradict Robertson, all the silent readers accessing the blog soon or later will begin to take his brazenly unscientific stuff serious, and begin to believe he is right.

    What motivates Robertson to believe that only positive anomalies can mean ‘true’ warming? Why does he not understand that a change of the reference period automatically changes the anomaly values wrt the x-axis, but without modifying the trend?

    *
    1. Here is a chart showing the UAH data as anomalies, as usual since years wrt the mean of 1981-2010:

    https://drive.google.com/file/d/1ZC3f6rSC-9zA7cWNMa1NTc1a_ndK7LjH/view

    So, according to Robertson, there is a recovery from cooling (a ‘rewarming’) between 1979 and 1995, and a TRUE warming [sic] which, he thinks, begins after the trend line passed the baseline.

    *
    2. But wait… some years ago, UAH’s reference period was quite different, namely 1979-1998.

    This leads to a new 12-month vector, each month of it now containing the average of all corresponding months in the new period.

    That gives us, out of the same absolute data, another anomaly chart:

    https://drive.google.com/file/d/18_g0W7CnY4TTqSEzAiwZokj0PKjMn9JW/view

    OMG! Now, again according to Robertson, the recovery from cooling is reduced by years, and ends already in 1989! The TRUE warming phase now has become outrageously long! Oh Noes.

    *
    3. So let’s save Robertson’s honor, by moving on to a baseline hopefully more pleasing to this genius: for example, 1990-2019.

    We now obtain, still out of the same absolute data, a third chart:

    https://drive.google.com/file/d/1H0s9JrnMqy4JjRUgkx0lLN2RTSm8Ivoq/view

    Ha! Now, the recovery from cooling is extended, up to 2004! Great!
    The TRUE warming is reduced to a decent minimum. Greater!

    *
    4. What will Robertson tell us, if he still enlightens us with his ‘science’ in the year 2035, the decent warming then is still the same as now, and Roy Spencer’s successor introduced, a few years before, WHO’s most recent reference period proposal, i.e. then 2001-2030 ?

    *
    But instead of accepting his mistake, Robertson probably will pretend that these graphs all are faked, and contain fudged UAH data.

    He never will give up, and always will come here again and again with his spurious ideas.

    Decades ago, I had to do with colleagues a la Robertson. Their motto, their fundamental attitude was:
    – rather make assumptions than ask questions;
    – never admit they are wrong;
    – but claim at the right moment that they have in fact always supported what they fought so hard before.

    Good grief!

      ” What is it about negative anomalies you don’t understand? A trend with negative anomalies does not indicate a warming of the atmosphere: it indicates a recovery from cooling. That situation prevails till you reach the baseline then true warming begins.”

      Incredible. Simply and utterly incredible.

      A baseline is a quasi-arbitrary choice from which to make anomalies of the absolute data. We could lower the baseline to match the lowest anomaly and say that it is a warm system getting warmer, or we could match it to the highest anomaly and say it is a cool system that hasn’t yet achieved warmth.

      And yet the data in real terms would be unchanged, and the trends that might be calculated from these data would all be exactly the same no matter where the baseline was. The arbitrary choice of baseline says nothing about the behaviour of the system, and the distribution of negative and positive anomalies as a result of baseline position is also arbitrary and the different signs of the values say nothing whatsoever about the behaviour of the system.

      That Robertson gets this utterly basic understanding so bone-headedly wrong completely disqualifies any opinion he might have on related issues. It’s not a question of opinion, this is stats 101 he is failing in a glaringly obvious way. It’s primary school easy to get the concept, but Robertson doesn’t.

  51. A linear trend is meaningless for non-linear temperature data.

    Also, CO2 levels have been rising since the trough of the Great Recession in 1932, so starting a trend in 1979 makes no sense.

    The global average temperature is a statistic with low value – not one person lives in the average temperature.

    Much more important are the details: Warming is mainly at high (cold) latitudes, mainly during the six coldest months of the year, and mainly at night.

    That’s a different story than a single average.

    Warmer winter nights in Alaska — is that bad news?

    Our planet has mild multi-hundred year warming and cooling trends, according to ice core studies.

    We’ve been in a warming trend since the 1690’s — the only other “choice” would be a cooling trend.

    Which would you prefer?

    I prefer warming and wish we had more global warming in Michigan, where we live.

    You can have your linear trend line statistic — the actual climate where we live is important to us, not some global average statistic.

    • bdgwx says:

      Dr. Spencer starts the trend in 1979 because that is the earliest year in which he had data. In other words he had no choice. If you want a trend to start in 1932 there are many datasets to choose from. I’ll recommend Berkeley Earth because the data and methods are easy to access.

      The global mean surface temperatures is valuable. It is one of the defining metrics for global warming so it provides an essential test point for global warming hypothesis. It is also correlated with sea level, sea ice extents/area, and various other global properties.

      From ice core evidence we do see variability in the implied global temperature. However, the contemporary warming era though perhaps not unprecedented is certainly anomalous in the record.

      It does not matter what temperature trajectory I prefer. Mother nature does not listen to me, you, or anyone else. It acts only in accordance with the laws of nature. So your question of which one I prefer is completely irrelevant to this line of discussion.

      A linear trend has limited, but powerful utility. It is a first order analysis to detect if there has been change, and to estimate how much change overall, within uncertainty limits.

      No one is claiming the climate could or should change in a straight line, so no need to introduce any srtaw men into the discussion. And if one is going to explore non-linear trends, then the analysis has to be very rigorous. I’ve seen very little evidence of that for blog-level curve-fitters. No formal estimate, no uncertainites is the usual red flags.

  52. bdgwx says:

    TLS dropped to 0.00C. The UAH record has 3 TLS spikes. The first two occurred because of volcanic activity. The most recent spike is hypothesized to have occurred because of the Australian wildfires. The first 2 spikes took several months to wane. It is difficult to draw conclusions from one data point, but this most recent spike early in 2020 and the subsequent drop in April is more rapid. If TLS continues to drop further then maybe the typical TLT cooling that we’ve seen succeed TLS spikes may not pan out. I had been expecting further declines in TLT this year. I may have to temper my expectations a bit.

  53. bdgwx says:

    Also noteworthy is that the TLS-TLT trend has increased to +0.42C/decade with this update.

    For those that may not be familiar this metric is important because it eliminates some potential causes for the positive Earth energy imbalance and resultant near surface warming. For example…solar radiative forcing.

    It seems to me, that no one is buying the Lefty Utopia of the Green New Deal.
    And more people are realizing that alternative energies are a scam, and that they are having bad environmental consequences.

    One could say that alternative energy schemes, do nothing to lower CO2 emission {and I would argue have increased CO2 emission} but one could argue that there could be a significant concern in regards of future global energy needs.

    I would say, if you are focused mostly on CO2 emissions, that one’s only solution lies with nuclear energy.
    Nuclear energy is also a safer and cleaner way to make electrical energy, and think that would more important than the aspect of lower CO2 emissions.

    One could argue that US, doesn’t have a near future energy problem- and what I mean by near future is within next 100 years.
    Whereas China does have near future energy problem, but it seems a large part of China’s problem will be solved by developing more nuclear energy- which they are doing- and so is India.

    It seems the future energy needs are mostly about getting countries out poverty, it appears that nations wanting to get out poverty, the most in the future will be the nations in Africa {and assortment of other nations, but keep it simple, we could focus on Africa]. One say from outsider prospective that China still has large problem with poverty, but their government plan does not seem focused doing much about, now, or in near future. Whereas with India, it seems that resolving poverty remains a strong focus, mainly because it’s a democracy and seems to only continue to grow as a democracy.
    Or China seems it will replace coal power generation with nuclear energy, and India will mostly add nuclear energy {and of course will get other energy sources}
    Of course it seems likely that with China and India focusing on nuclear energy, that that could “export” nuclear technology to countries in Africa in the coming decades.

    Anyhow, I am not big fan of nuclear energy, mostly because tends to be governments being the energy provider. And I tend think governments can have huge capacity be very stupid- and careless.
    This is not so much the case in US or even Europe, rather it’s more of a matter of, excessive involvement by government.

I regard the Democrats and our federal government here in Canada as politically-correct annoyances that we must hold our noses and bear in a Democratic country.

        I don’t just blame lefties for raising taxes. We can assume that all politicans, including “read my lips, I won’t raise taxes” will raise taxes. I would not vote for libertarian, because I imagined, it would not raise taxes. I would not call Schwarzeneggar a uber right-winger, incompetent, a weenie, a dolt, seem to sum him up.
        If had to pick anyone, who cause California to be a one state party {dem} it would be Schwarzeneggar, mainly because a Rep can be competent, and no one, can say Schwarzeneggar was competent.

        Well, if nothing else this pandemic, is going to reveal pols for what they are.

        On topic of Canadians, you guys should make sure that you are not deficient in Vitamin D. Your sun at noon, probably provides it, but apparently, the sun nearer the horizon, doesn’t. Don’t need to get a tan, but get some {btw, sunscreen blocks it}.

          Damned if you do (skin cancer) and damned if you don’t (vitamin D deficiency). My trade off is to take 2 x 1000 IU (25 mcg) vitamin D3 tablets at least every other day.

          You can acquire cabin fever pretty easily up here, especially on the west coast where the sky is overcast much of the winter. It doesn’t seem to bother me one way or another, although sitting in front of a computer rather than being out in the fresh air and the elements is not very natural.

    I think it’s interesting that the headline is that we’ve had a big drop since February.

    • barry says:

      Yes, when ‘skeptics’ protest that ‘warmists’ make too much of month to month changes when its warming, viola! Here is a leading skeptic announcing a record-breaking 2 month drop.

      I wonder how many people realize that this is a weather, not climate phenomenon. I have no doubt that the author knows the difference.

      • gbaikie says:

        IF global temperature were to magically stay at this month’s average temperature [for forever} then there was no global warming.

        If take high peak temperature and were to magically stay at that month’s average- forever then there was some global warming, though one could argue about when it “mostly” started.

        But any global warming that is “worth” anything as an idea, is significant future warming {which hasn’t happened yet].

        And it’s similar to the plague from China, the concern is will it get worst than it’s already been.

        Or some think if we remove all “lockdown measures” in the US tommorrow, then is we get twice as much deaths and twice as much serious illness within the near future. And near future would be
        by say, Sept 2020.
        Or present situation is not the effect more 1 year in the future, rather it’s months in the future- whether it’s less 2 months or as much as 6 months.
        Or “forever” with Chinese virus is about +1 year, with climate is practically about 20 years. As within 12 years we are DOOMED.
        Though one could say within 50 years we are “really doomed!”
        Or “forever” from climate could be as much as 50 years and “forever” for virus could be 2-3 years.
        But one could say the focus with Chinese virus is mostly months, which some claiming could be worse then what we already have experienced. Though of course part of what have experienced is crash in economic activity, and many suffering from this imposed hardship {and some aren’t having much suffering- a little inconvenient, is what I count it as}.
        Now if we end national lockdown tomorrow, and is not much of consequent of lifting it, then people are going to question whether the lockdown was “worth it” but mostly they will backseat drive, the chosen route taken- imagining if only did —— it would have been better.
        But what is important now and in the future, is the prediction of what happened if end lockdown now, or in 2 weeks from now, and how it’s done- rip off bandage, or take gradual cautious steps to test the waters, before ending completely the lockdown.

        • barry says:

          Which nation are you talking about?

          The irony of a successful lockdown is that the numbers stay low and critics then announce that there was no problem, giving nature the credit for wise human decision-making.

          • gbaikie says:

            Too early to know what a successful lockdown looks like, usually one quarantine the people infected- and not entire nations- and the entire world.
            One could say that China pretty used to being in lockdown- and kicked out news reporters and going absolute total state propaganda.

            As is widely known, China’s military future is planning bioweapons, space dominance, and cyber warfare as key to future wars.
            Their space dominance is not working very well, but cyberwarfare is looking pretty good, and we will see about their bioweapon efforts.

            But personally, I think nukes work pretty good, but of course there number of steps to take before we get to nuking them from orbit.

          • barry says:

            Though some people seem to forget, there is more than one country in the world. Countries that have had different responses at different stages of the pandemic, and we can compare them.

            Success = fewer deaths from the disease. A complicating factor is the economic repercussions of various policies to contain the pandemic.

            Do you have anything cogent to add, or have some half-read articles given you some some half-formed ideas that wiltingly prop up your vacuuous condescension?

            I’ve been watching Sweden, because at one point its figures were very similar to Australia’s on the same day. Of particular note after time and quite different approaches is the very different death rate, although Sweden’s case numbers have also taken off compared to Australia’s. There are various factors to account for, but the difference is stark enough to say with some cponfidence that more stringent restrictions prevent infections and death.

            Anyone familiar with stats and the various factors will understand the strong caveats on the numbers. Of course, those folk won’t include anyone telling people to check the figures for other countries, as if somehow when they speak the figures magically get more certain.

          • Amazed says:

            And Belarus? While you are at it, remember that influenza epidemics tend to be more severe in winter. Australia and Sweden seasons are reversed. If you are going to say that corona viruses are not season sensitive, ask why colds and influenza like illnesses are more common in winter. Corona virus is responsible for many colds.

            Alarmists comparing apples to oranges. Try comparing Sweden (minimal lockdown) with USA, UK, Italy, Spain. Now tell me how many lives your lockdown saved. For more confusion, look at deaths per capita, and draw your conclusions. The future is unknowable.

          • barry says:

            Flu season in Australia is April to August. COVID infection rate dropped precipitously through April, as did the death rate.

            Do you ever check what you say?

            US, UK, Italy and Spain were slow to get their lockdowns going. UK was going on about herd immunity while numbers rose, then they changed their tune and slowed the cases with lockdown. Italy had already been well-infected before they imposed lockdown. Same with Spain. And their citizens were not very compliant to begin with (that changed). Go ahead and compare cases and fatalitites with dates that lockdown and other measures were mandated. For example, Italy initiated partial lockdown early March, and imposed the strongest restrictions country wide on March 21. Have a guess what date the infection rates declined from?

            You do the numbers for Belarus. You can find all the data you need by searching worldometer coronavirus. That’s all the help I’m giving you, lazybones.

    When are RSS and UAH going to resolve their big differences?

    Its like when the heavyweight boxing title got confusing with various WBA WBC QED titles.

    Are we just going to have to accept that there is no undisputed LT temperature trend?

    • E. Swanson says:

      Nate, Which “big differences” are you looking at?

      The RSS TLT series is based on a different base period than the UAH. The RSS data excludes the areas over the Antarctic from 70s to the South Pole and over regions with high mountains, while UAH includes these regions. The RSS TLT is calculated from only one channel of data, their TMT, while the UAH LT is a weighted mixture of MT, TP and LS data and the processing of those channels is different than the RSS TMT.

      There are other differences in approach and processing as well, so I wouldn’t expect then to agree.

    • bdgwx says:

      We get that RSS-TLT and UAH-TLT are fundamentally different. The problem is UAH-TLT is +0.135C/decade while RSS-TLT is +0.212C/decade. That’s a huge difference even considering the fundamental differences.

      • Nate says:

        Yes well put.

        ‘he RSS TLT is calculated from only one channel of data, their TMT, while the UAH LT is a weighted mixture of MT, TP and LS data and the processing of those channels is different than the RSS TMT.’

        If a result is so sensitive to analysis method, then it is not very useful to science.

        • E. Swanson says:

          I suggest that the proper question is: “Which analysis yields the most accurate result”. Don’t forget that there are also other groups and other analytical techniques, it’s not just UAH vs. RSS, though it’s correct that a “Lower Troposphere” analysis is only provided by those two, as far as I am aware.

          The original TLT from UAH was a correction to the MSU Channel 2 data, which was influenced by the known stratospheric cooling. There are other ways to “correct” the channel 2 data, such as the TTT from Washington State. RSS also provides a TTT series on their web site, for which the latest global trend is 0.176 K/decade.

          All of these efforts must also be corrected for orbital drift in LECT and orbital decay, which makes combining the data from some 13 satellites difficult. With the UAH LT approach, three channels must be combined, including MSU channel 3, which had some serious problems in early years, so much so that RSS TTS data doesn’t start until 1987.

        • barry says:

    Are you talking about the fudged NOAA/GISS records, which are set using climate models and by eliminating regions with cooler temperatures? For example, NOAA has only 3 reporting stations in California, all of them along the warmer coast. The have one in Canada covering the entire Arctic. And the colder temperatures at high altitude in Bolivia have been eliminated with Bolivia being given a temperature based on averaging temperatures from warmer nearby locales.

    With regard to your claims above, you could have fooled me based on my experience in the Vancouver, Canada region. Normally we have mild winters due to the Japanese current but this year our winter was dominated by record cold spells. Even now, in May, the temperatures continue to be below average.

      For example, NOAA has only 3 reporting stations in California, all of them along the warmer coast.

      Weird. When I got to the NCEI website and search for stations in California I see like 500 of them.

      • Gordon Robertson says:

        bdg…”GISTEMP does not use a GCM.”

        GISS does, Gavin Schmidt and James Hansen of GIS are/were climate modelers.

        “When I got to the NCEI website and search for stations in California I see like 500 of them”.

        Of course, but NOAA only uses 3 of them in their calculations. I posted a link several times to a direct admission by NOAA that they have slashed their reporting surface stations GLOBALLY from 6000 to less than 1500. If they were using all the 500 stations you claim, 1/3rd of their reporting stations would be in California.

        According to chiefio, GHCN has slashed the reporting stations by 90% since 1990.

        The Canadian Arctic has many more stations than are used by NOAA. They were using only the station at Eureka, to cover the entire Arctic, last time I looked.

        • bdgwx says:

          Yes. Hansen does modelling studies. That is something different from the GISTEMP dataset.

          Yes. NOAA, NASA, Berkeley Earth, etc. all use a subset of the available stations. If you have reason to believe using all of the stations will significantly change the result then you test that hypothesis. I don’t think you’re going to see much of a difference. The reason I don’t think you’ll see a difference is because reanalysis assimilates many more surface observations plus observations of varying types and varying levels of the atmosphere and the warming trend from those isn’t significantly different. For example…the ERA trend since 1979 is 0.1901C/decade and the Berkeley Earth trend is 0.1898C/decade. ERA assimilates tens of millions of observations every day while BEST is a mere fraction of that. It just doesn’t matter.

      • barry says:

        The link you have provided many times does not say what you says it does. That is your very own paraphrasing. Here, for the dozenth time, is what they actually say.

        “The physical number of weather stations has shrunk as modern technology improved and some of the older outposts were no longer accessible in real time.

        However, over time, the data record for surface temperatures has actually grown, thanks to the digitization of historical books and logs, as well as international data contributions.”

        https://web.archive.org/web/20130216112541/http://www.noaa.gov/features/02_monitoring/weather_stations.html

        I’ve looked and looked, and nowhere do I see NOAA “admitting” that it “slashed” thousands of stations.

        That is entirely your spin – and it is wrong because the stations weren’t slashed, the vast majority remain in the GHCN database, and the reason there is thousands more in the past than the present is that only a subset is updated in real-time, and the majority of stations have been added retrospectively.

        Which is explained in the source material Chiefio first copied the graph from many years ago…

        https://tinyurl.com/gp6z3qp

        “Because most instrumental networks were established to monitor local weather and not the long-term climate, there are practical problems in using these data to study climate change. For instance, the records are often not digitized and/or are not readily available outside of the country in which they were measured…

        This is not some post-facto rationalization, either. This is the 1997 description of how NOAA acquired historical data for GHCN. Read on and learn.

        “When possible, we tapped related projects for potentially useful data. For example, N.C.D.C recently collected and processed station normals for the period 1961-90 as a contribution to WMO (WMO 1996a). On occasion, a WMO member country supplied year/month sequential data in addition to the 30-yr means and other statistics. Upon receipt of such records, the member country was contacted in regard to contributing the time series data to GHCN. The Colonial Era Archives initiative was also tapped in this regard (Peterson and Griffiths 1996). Started as a GHCN subproject to acquire data in very data sparse regions, this initiative digitized early temperature and precipitation records for stations operated by various European countries in their respective overseas colonies. Data for hundreds of early African stations have been incorporated from this source and the digitizing effort has been expanded to Asia and South America (Peterson and Griffiths 1997)…

        Pray tell how Colonial Era archives are able to be updated? Answer, they can’t be, they are archives. And this is the form of the majority of the addition to GHCN in 1997. One-time additions that could not be updated, like the then 1500 stations that could be updated regularly. Read on.

        “The reasons why the number of stations in GHCN drop off in recent years are because some of GHCN’s source datasets are retroactive data compilations (e.g., World Weather Records) and other data sources were created or exchanged years ago.”

        How many years have you continued to promulgate falsehood about this? The great majority of GHCN station data was never available in real time and can’t be updated like the core group stations’ data that NOAA acquires monthly.

        The reason there is more data than just the group that regularly update is that NOAA went back through archives and digitised millions of data records.

        The irony is that you think stations were ‘slashed’, when in fact, they were added retrospectively. And because you can’t put this together in your brain for some strange reason, you have repeated this dirty little smear for years.

        This has been explained to you more than 20 times, with references and links to your own source and the actual source document that first provided and explained changes in station count.

Before you start your futile search to find evidence that would support your drivel such that anyone would take it seriously, you should take into account that conspiracy ideation is ill-supported by a confusion between a lack of warmth and a lack of warming.

        • Dr Roys Emergency Moderation Team says:

          It is rotating – about the Earth/Moon barycenter, and not on its own axis. If it were rotating on its own axis at the same time, we would see all sides of the Moon from Earth.

          • Ball4 says:

            Elliot, DREMT has been long confused about orbiting and rotating on an axis being independent mechanics. If the moon were rotating on its own axis at any different rate than current, only then would we see all sides of the Moon from Earth.

          • Dr Roys Emergency Moderation Team says:

            Orbiting and rotating on an axis are indeed independent mechanics. The Moon is just “orbiting”.

          • bobdroege says:

            Except Astronomers have identified the two axes that the moon orbits and rotates around, and they are not parallel.

            So the moon therefore rotates on its axis as it revolves around the earth on another different axis.

            Maybe those who don’t get this should inquire about attending their local junior high school.

          • Dr Roys Emergency Moderation Team says:

            The moon &ldquo;orbits&rdquo; about a barycenter – a point, not an axis.

            Nobody said the moon couldn’t have a bit of “up/down” wobble (libration of latitude) and “side/side” wobble (libration of longitude) whilst it orbits. After all, the moon isn’t held in place by a rigid rod. It’s just gravity doing its thing, as best it can, but it’s not going to be held perfectly in a fixed position the whole time.

          • bobdroege says:

            Nope it’s not around a point, it’s around a line because it orbits along a plane which is perpendicular to axis of revolution.

            The longitudinal libration is because the moon revolves in an elliptical orbit so it doesn’t orbit and rotate at the same speed.

            Say something else that is wrong that shows you don’t understand the orbit of the moon.

          • Dr Roys Emergency Moderation Team says:

            Yes blob, the libration of longitude is an apparent East-West wobble (side to side, like I said) as viewed from the Earth over time. It’s good that you’re learning some of the basics, finally. No, the moon definitely orbits the Earth-moon barycenter, which is a point and not a line/axis.

            https://en.m.wikipedia.org/wiki/Barycenter

            “In astronomy, the barycenter is the center of mass of two or more bodies that orbit one another and is the point about which the bodies orbit.

          • bobdroege says:

            You need the axis to fully describe the orbit, which is in a plane perpendicular to the axis.

            Saying the moon orbits the earth moon barycenter isn’t telling the whole story.

          • Dr Roys Emergency Moderation Team says:

            You are trying to describe the phenomenon of lunar obliquity. There is no orbital axis, but if you were to draw a line through the moon perpendicular to its orbital plane then that line deviates by the line going through the moon’s north and south “poles” by six degrees or so. That is the lunar obliquity. This has been determined by studying the libration of latitude from Earth, and from knowledge of the deviation of the moons orbital plane from the ecliptic.

            You could do the same with a moon that does not rotate on its own axis as you see it. As you define lack of axial rotation, a moon moving in this manner would appear to rotate, CW, over the course of the lunar month as viewed from Earth. Thus you could determine where is the north and south “pole” for this moon, and how those poles wobble back and forth over the course of the month, if indeed they did. Then, with knowledge of how the moon’s orbital plane deviates from the ecliptic plus the observations of the moon’s libration of latitude, if present, you could determine the lunar obliquity…and this is all in a moon that you would consider not to be rotating on its own axis. Therefore axial rotation is not proven by lunar obliquity.

            “would appear to rotate” ‘pole’ ‘if indeed they did’

            Or, much simpler and less erroneous: this is compelling evidence that it does rotate around real poles.

            It reminds me of the great lengths they went to with the whole development of epicycles, to avoid the much simpler Sun-centered model, because it conflicted with what became their religious belief.

            There are planned missions to land near these imaginary lunar ‘poles’.

            Bob, You should ask him how we know where these lunar poles even are, if it has no rotational axis.

            Since it is a rotational axis that DEFINES where a planet’s poles are.

          • Svante says:

            Or stand on the moon and watch the stars rotate in the sky.
            The poles are where the stars rotate in a circle straight above you.

          • Dr Roys Emergency Moderation Team says:

            Exactly, Svante…there are many such ways to determine where the “poles” might be, which don’t involve any proof of axial rotation. Just the way the moon moves in its orbit.

          • Svante says:

            Yes, it will be very obvious when you stand there.
            You are absolutely still, but the universe is rotating around you.

          • Dr Roys Emergency Moderation Team says:

            No, not at all. Of course your location would be changing wrt the fixed stars, since orbital motion necessitates such a change of orientation. You would be on the moon, which is moving around in a big ellipse. Nobody is arguing that it faces the same fixed star throughout this motion.

          • Nate says:

            “The poles are where the stars rotate in a circle straight above you.”

            Yes Svante. And the Moon has an AXIAL TILT of 6.67 degrees.

            Not sure how it can have an axial tilt without an axis. But Im sure DREMT can manage it.

          • bdgwx says:

            Rotation happens when there is angular velocity relative to an inertial reference frame. A reference frame fixed on the stars is inertial. The Moon has angular velocity on that reference frame. Therefore the Moon is rotating.

            There would be a similar problem if you said a passenger in a car was not accelerating because you arbitrarily decided to use the non-inertial reference frame fixed on the car. Same fallacy; just with translation instead of rotation in this case.

            -The Moon has an orbital axis.

            -The Moon has a SEPARATE rotational axis.

            -This axis determines where its poles are.

            -There is an axial tilt of 6.67 degrees between the rotational axis and the orbital axis.

            -On the Moon the stars move in circles around the rotational axis, not the orbital axis.

            -Concepts like POLES and AXIAL TILT cannot even be defined without a rotational axis.

            These are the facts that are universally agreed upon.

            There is no amount of hand-waving gobbledegook that DREMT can give that can explain these facts as ‘JUST ORBITING’.

            We’ve been thru all this before. The rerunning of this argument tape turns out the same everytime, and DREMT is wrong each time.

          • Nate says:

            For completeness another couple of Moon facts.

            -The Moons rotational angular velocity around its rotational axis is CONSTANT due to conservation of angular momentum.

            -The Moons orbital angular velocity around its orbital axis is NOT FIXED, due to its elliptical orbit varying its distance from its orbital axis.

            -As a result, we do not see the same face of the Moon. The longitudinal range that we see varies during its orbit. The Moon wobbles side-to-side.

            DREMT will declare that he can explain these facts as JUST ORBITING, but he never actually does.

    barry…”And yet the data in real terms would be unchanged, and the trends that might be calculated from these data would all be exactly the same no matter where the baseline was”.

    Without a baseline there are no anomalies. An anomaly is a departure from an average over a range.

    When you look at each anomaly on the UAH graph, the anomaly temperature is meaningless. They cannot be translated into absolute temperatures. Each anomaly is relative to the defined baseline.

    If you defined the baseline on the year 1998, with a global average well above average, anomalies from ensuing years would all be below the baseline, except for 2016. On the other hand, if you defined the baseline on cooler years, as is the practice of NOAA and GISS, anomalies from ensuing years would appear warmer than they are.

    • barry says:

      Of course the anomalies can be translated back into absolute temperatures! You work out the average absolute temmperature for the baseline period, and then add that value to each anomaly and viola! You have your absolute global temps back. It’s not even hard. GISS give you the absolute value somewhere on their pages. Maybe the other institutions do the work for you. Roy has probably done so, somewhere, and Bindidon is able to give you the value by examining the UAH data files. The information is all public domain.

      This nonsense about warming not “truly beginning” until anomalies turn positive is just incredibly wrong and stupid. The baseline does not define the actual system as being ‘cold’ or ‘warm’ just because of the sign of the anomalies. You can’t use anomalies for quantitave judgements like that. They are useful for plotting the behaviour of the system.

      If you drop the baseline by 10 degrees C, what changes? Nothing. The change from one data point to another remains the same, and the trends derived from those data remain exactly the same. You’d be an idiot to say that the system was now “incredibly” warm, just because the baseline made it look so.

    • barry says:

      Bah! Incredulity causes typos:

      You cant use anomalies for qualitative judgements like that.

      No. It does not matter where you put the baseline. The anomaly values are not cooler or warmer either way.

      Think about it this way. F and C are both anomaly based scales themselves. F is baselined on the freezing point of a salt brine solution whereas C is baselined on the freezing point of pure water. Is 32F warmer than 0C because Fahrenheit decided to use a cooler baseline vs. Celsius’ baseline? No, of course not.

    • E. Swanson says:

      Gordo, It’s well known that the satellite brightness temperature anomalies can be converted back to “absolute”(??) temperatures. UAH provides the average temperature data, which even you could add to the monthly zonally averaged data to make the reversion.

      And, as I’ve pointed out before, the short term month-to-month variation in anomaly values aren’t important, it’s the trend of the time series which tells us what’s happening.

    • Bindidon says:

      barry

      ” Of course the anomalies can be translated back into absolute temperatures! ”

      Correct!

      ” You work out the average absolute temmperature for the baseline period, and then add that value to each anomaly and voila! You have your absolute global temps back. ”

      Not quite so.

      Exactly as anomalies, as understood by all people working with them, are not simply obtained by subtracting the average absolute temperature for the baseline period from absolute values, conversely absolute values cannot simply obtained back that way.

      The reason is that anomalies are not only departures from a mean; they are also the result of removing the seasonal dependencies (what Roy Spencer names ‘the annual cycle’) out of the time series.

      Thus, for a monthly time series, a baseline is not a single value: it is a vector of 12 values, each being the average of all corresponding monthly values within the reference period.

      Things become even a bit more complicated when you have a grid: in this case, each grid cell has its own 12-month baseline vector, like e.g. in

      https://www.nsstc.uah.edu/data/msu/v6.0/tlt/tltmonacg_6.0

      This file contains 12 grids, one per month; each grid contains in each of its cells the average value of all absolute values for this month in the years 1981 till 2010.

      If you now would need daily anomalies, you then must construct a vector of daily averages, like in

      ftp://sidads.colorado.edu/DATASETS/NOAA/G02135/north/daily/data/N_seaice_extent_climatology_1981-2010_v3.0.csv

            Had.CRU suffers from a lack of coverage at poles, but at least doesn’t interpolate. GISS UHI correction is potentially less than optimal, and it interpolates where there is no coverage. RSS has less coverage than UAH. Berkley Earth… doesn’t seem to have many disadvantages that come to mind, and yet it is still another estimate, not gospel. All the surface records contain adjustments, because the raw data has problems. All the satellite records have adjustments because the raw data has problems.

    Debate regarding differences in reported average global temperatures ignores the 800 lb gorilla in the room: Water vapor.

    It is not actually very hard to calculate the expected water vapor increase as a result of temperature increase. Also, WV increase has been measured using satellite instrumentation. WV calculated from Had-CRUT4 temperatures is compared to measured WV at https://drive.google.com/open?id=1XFc92GAl-NXOqwiJKiAZzfEbb9x4BKND
    The trends show that WV has been increasing faster than possible from temperature increase (feedback). This was corroborated by similar calculations using temperatures reported by UAH, NASA, RSS, and GISS. Therefore the alarmist’s contention that warming initiated due to CO2 increase is impossible.

      Dan, you can’t keep your own stories straight since you wrote many times earlier: “(I) contend that CO2 has no significant effect on climate in spite of its being a ghg.”

      Which is it then: 1) warming initiated due to CO2 increase is impossible or 2) has no significant effect?

      And proper debate does not ignore WV. Proper debate knows humidity at the equator affects near surface temperature (atm. emissivity looking up) more than at the less humid poles & this is taken into account.

      • Dan Pangburn says:

        Ball,
        They are both true. More CO2 makes more emitters available in the stratosphere which has a cooling effect so the over-all effect of added CO2 might even be slight cooling.

        I never claimed that they ignore WV; it’s that they account for it incorrectly. They calculate WV increase based on temperature increase instead of using actual WV measurements.

        More humidity produces warming throughout troposphere (except, as pointed out at the end of Section 3 in https://watervaporandwarming.blogspot.com , near the poles where humidity is always low because of the cold).

        Debate is of little use when some participants have been falsely indoctrinated and are unaware of their misguided perceptions. As Mark Twain said “It is far easier to fool someone than to convince them that they have been fooled”.

        • Ball4 says:

          “They calculate”

          Who is they? Meteorologists have roamed the globe measuring wv looking up through the column to use in atm. emissivity studies, wv through the column with soundings, and satellites measure the wv looking down through the column. Humidity is daily continuously measured by weather stations around the globe.

          Precipitable wv in the column can also be calculated* but it’s messy which is why meteorologists much prefer to use the proper measurements rather than to calculate wv and humidity as you incorrectly write.

          Since you write “they” account for it incorrectly you MUST have an example to show where practicing meteorologists do the calculation incorrectly. Otherwise you have no basis for the claim, like many around here. So show it.

          Look up definitions for impossible and insignificant as your claim they are the same is preposterous. Maybe a dictionary will help you keep your stories straight, not contradict yourself showing lack of understanding even basic meteorology.

          *To be the least bit credible here, your task then is to show their incorrect calculation and your valid corrections for their calculation.

          NB: Selected beginning atm. thermo. texts show how to do the precipitable wv calculation; consulting one would help you learn how to do the calculation properly & maybe even show us you can do so. But from your comments I doubt you can do that.

          “so the over-all effect of added CO2 might even be slight cooling.”

          That would take a power source and CO2 does not have one so its passive temperature changes due its ppm changes at near atm. surface and upper regions have to cancel to follow conservation of energy i.e. Sam Clemens was right.

          • Dan Pangburn says:

            Ball,
            The ‘they’ referred to are the GCMs. Sorry that wasn’t clear. They (the GCMs) calculate WV change based on temperature change and keeping relative humidity constant.

            Your statement that I claimed that impossible and insignificant are the same is what is preposterous. As you should realize, initiated by CO2 and [after being initiated] CO2 can have no significant effect [the CO2 might be very slightly either warming or cooling of what the trend would be if there were no CO2 effect] are compatible.

            I have never claimed any skill in meteorology and have no interest in gaining any. Meteorology is quite good at predicting weather for a few days but contributes little to and perhaps interferes with understanding climate change.

            Your last paragraph indicates that you misunderstood my statement. Probably my fault. Replace ‘slight cooling’ with ‘reduction of the warming that would occur with increased WV if there were no effect from CO2’.

          • Ball4 says:

            Edit per Dan: “More CO2 makes more emitters available in the stratosphere which has a cooling effect so the over-all effect of added CO2 might even be reduction of the warming that would occur with increased WV if there were no effect from CO2.”

            Dan, that edited wording makes so little sense I’m appalled. It confirms your claim you have no skill in meteorology & yet you are attempting to point out errors within the meteorologist’s GCMs. Try again.

            Let’s helpfully try the substitution “GCM” for “they”:

            “it’s that GCMs account for it incorrectly. GCMs calculate WV increase based on temperature increase instead of using actual WV measurements.”

            That doesn’t make any helpful sense either. How could GCMs use actual WV measurements except at given GCM initial conditions? Continuously re-initialized GCMs do predict the weather a few days out well enough to make personal weekend plans that usually work out well enough to pay attention to weather reports.

            Your second paragraph is so unintelligible that no helpful comment is possible.

    • Dan Pangburn says:

      Ball,
      I doubt that you are as dense as you display.

      If you do not have anything rational to say about the observation that water vapor is increasing faster than possible from temperature increase and that this demonstrates that the alarmist’s contention that warming initiated due to CO2 increase is impossible then further discussion would be merely a distraction.

      • Ball4 says:

        Dan, I agree there is no progress to be made until you obtain some skill in the field of meteorology.

        You will learn from study in that field: 1) near surface atm. warming initiated due to CO2 increase is possible and 2) has no significant effect if by significant is meant much more than the predicted and subsequently measured/observed ~0.075C/decade increase including all the natural humidity changes.

    Two months later, on September 13:

    “3.4 region has just made a fresh 52 week low this morning @ -.509.

    1+2 has made a fresh low @ -1.446

    This confirms once again the trend is lower as of today. Still heading towards La Nina.”

    Fail

    ENSO remained very close to neutral for the last half of 2019, and headed into el Nino condiditions in 2020. Though NOAA’s chart has crossed the el Nino threshhold, their advisory is that neutral conditions are present and expected to persist.

    I find the point of view in these posts interesting.

    The lead few paragraphs emphasize the 2nd largest drop in some metric to which no one previously gave much thought, that is, the two month drop.

    Under the lede there’s discussion that the trend has increased to 0.14/decade. Which in reality means 0.1349 or so has gone to 0.1351 or so which is pretty negligible difference excepting that it’s amplified by the conventions of rounding to two decimal places.

    For the linear trend to have increased however slightly it follows that this month’s data is above the trend (about 0.05 C if one does the math). So one might just as well say that this month was pretty much what one would expect, only a bit higher.

    And the “2nd largest drop” is largely down to the fact that February was exceptionally high under weak El Nino conditions while April is unexceptional. February was in fact the highest (anomaly – linear trend) month outside of a strong (87-88) or very strong (97-98, 15-16) El Nino event.

    Ha ha ha haaa!

    https://chiefio.wordpress.com/2009/10/27/ghcn-up-north-blame-canada-comrade/

    This is really one of the dumbest, most ignorant posts I have ever read.

    Manifestly, Smith suddenly discovered at that time that the GHCN V2 directory was nearly empty.

    But… he did not notice that exactly at this time, NOAA moved all V2 data to the new, freshly born V3 directory.

    And of course Robertson has to fall for such chess! No wonder.

    Here are a few GHCN daily Canadian stations located in the Arctic…

      First, that is factually and mathematically incorrect. The warming trend is statistically significant.

      Second, later lows are higher than earlier highs.

      Third, the atmosphere takes up maybe 3% or so of Earth’s energy imbalance and is highly variable due to various heat flux processes. If instead we switch to the hydrosphere which takes at least 90% of the imbalance you’ll see that the later low are much higher than earlier highs…by like a lot.

It seems apparent he knew this covid contagion was coming and the lady being interviewed gives evidence that Fauci has connection to a Wuhan lab where Fauci’s department has been trading data with them.

        The woman being interviewed is a researcher who claims Fauci has patents on a vaccine. She is warning, based on her experience as a scientist, that such a vaccine, or any flu vaccine that is based on animal products, can potentially spread a covid-type infection.

        She has almost gone so far as to say the spread of this virus is intentional. This is a woman who worked for Fauci and became a whistle-blower trying to expose his creepy ways.

      binny…”In between, the US have entered the top ten of that stat (last column):”

      The top ten for what? What are the tests testing for, certainly not a virus?

      The current covid tests are converting RNA to DNA and amplifying the DNA after it has been made radioactive. The PCR method for DNA amplification is applied to a small sample of radioactive DNA and it is amplified while illuminated by ultraviolet light, which reacts to radioactivity. When they DNA reaches a multiplication of a certain level the ultraviolet light is reflected in different colours. At that point a person is claimed positive if the level exceeds an arbitrary value.

      EVERYBODY would test positive for this DNA/RNA because DNA/RNA is in every cell in the human body. The tests are only measuring a little more RNA in people who are infected with ANYTHING. The viral loading technique is a scam invented for HIV and it has been debunked. Why is it still being used?

      What has any of that got to do with testing for a viral load? It is INFERRED that the RNA converted to DNA using a reverse transcriptase enzyme is RNA from Covid 19. They don’t have the slightest shred of scientific evidence to back that claim. It is a presumption and it’s wrong.

      There is a perfectly good method for testing for a virus, why is it not being used? It could not be used for HIV because nothing showed up with the standard method. Some idiots reasoned HIV was there but there was so little of it they could not find it using the standard test. So the idiots decided to amplify DNA that was converted from RNA found in an infected person.

      Luc Montagnier who won a Nobel for discovering HIV admitted in an hour long interview that he did not purify HIV or see it with an electron microscope. He admitted to inferring its existence, claiming he THOUGHT that 1 in 1000 particles in an infected sample were HIV. He claimed in the same interview, that HIV will not harm a healthy immune system.

      Here’s the circular logic for viral loading:

      1)A virus is RNA contained in a protein coating
      2)RNA is found in infected people (also in non-infected people)
      3)Therefore the RNA must come from a virus.
      4)We have not seen the virus or isolated it, but we’ll call it covid19.

      That is about the most stupid pseudo-science I have ever encountered. They cannot find a virus using the standard method so they infer one using circular logic that makes no scientific sense.

      The logic was wrong for HIV where that viral loading technique originated. Kary Mullis who invented the PCR method and won a Nobel for his efforts got angry when asked about the viral loading technique. He claimed PCR cannot detect a virus. Mullis did HIV-related work, he knew about viruses.

      The number of deaths reported in the US jumped dramatically over a two week period from 500 to nearly 50,000. That is total bs. Fauci, of the US NIAID (infectious control) put his foot in his mouth by claiming there could be over 200,000 deaths related to covid in the US. Trump bit and began braying about that possibility. Now they are in damage control, trying to artificially elevate the number of deaths so they won’t look absolutely stupid.

      Trump has realized his error and he is pushing to get the US economy going again. He is being opposed by the likes of Fauci at NIAID and the US Center for Disease Control, who want to control the transition. I say, kick their sorry butts out the door and get on with it. Let the human immune system do what it does best.

      It was the same in the UK. They were following the Swedish model of using scientific analysis and watching the contagion on a daily basis to see where it would go. Then some bean-counting idiots at the Royal Society put out a ludicrous projection of 500,000 deaths based on a computer model. The UK immediately changed course and started locking the country down. They panicked.

      In the US, the head of the coroner’s association in Philadelphia is upset because they don’t have a body count that matches the inflated death statistics. In Minnesota, a doctor complained that the State is putting pressure on him to increase the number of covid-related deaths. They have urged him to report any death as covid-related even if the deceased does not test positive but he had been in contact with a family member or friend who had tested positive.

      As one scientist put it, the pandemic is not about covid, it’s about the hysteria and panic in the human mind.

            You don’t even look into things when you make a lying false post. The female scientist you are referring to was put in jail for stealing items. Read up on it.

            Peter Duesberg is an evil human with a cold heart. His false ideas on HIV caused the deaths of several people that could have been helped. He is a false prophet from the house of lies.

            I am no idiot. I like Truth. You hate it so you have nothing else but your lies, dishonesty and attempting to throw mud.

            You see everyone in the World as dishonest but you and a handful of lying dishonest contrarians who you blindly believe. The point is you are projecting your own dishonest mind unto everything and then you are not able to see that you are the lying dishonest one not the rest of the scientific world. Your own dishonest lying mind can’t see itself but sees everyone as it really is (which they are not)

            You think scientists are intentionally “fudging” temperature data and yet you have not read one article on what they are doing and why and then proposing valid skeptical arguments against some of their choices. No all you do is make the false lying claim they are intentionally “fudging” data to create warming that does not exist in reality. Now you say that authorities are “fudging” deaths in Covid cases. You have zero proof of this allegation. You have done no study to prove such claim. You just assume everyone (buy you and a handful of lying contrarians) is a dishonest liar like you are so you can’t believe anything and you do this all with no evidence or proof. That is a pathetic mind. Full of lies and dishonesty but can not ever examine itself to see if it is the source of all the lies and “fudging” it sees.

        So, is the number given for common seasonal flu, somewhat accurate OR is that also a scam?

          The numbers are all estimates. No one knows for sure if most people die from the flu or from underlying conditions. That applies equally to the current contagion. No on knows the accuracy of the infections or the deaths claimed espeacially when pressure is being applied to US medical people to list deaths as covid-related.

            But I would say that I am being optimistic about how smart we might be, when I say within 3 months.

          “While we topic of nullifying viruses,”

          Who is talking about that? The objective is to “flatten the curve.”

          A lot of people seem to be missing the point of lockdowns and social distancing.

          • gbaikie says:

            “Who is talking about that? The objective is to “flatten the curve.”

            No, it’s: “Who is talking about that? The objective was to “flatten the curve.”

            The flattening the curve is done, already, and it’s done globally.
            Though obviously the virus still exist, and we no clue when could stop existing. And no clue if any vaccine will work or how well it works if it works at all.

            The only question at this point, is what is best way to go, after the curve has been flattened.

            In the beginning the virus was a low risk of death. And even a low risk of death to the population which has highest risk of death- which was over 65.
            But in terms of risk of serious illness which doesn’t result in death, that was why you needed a lockdown.
            Or since this started, mid Jan 2020 {or earlier} we needed isolation of 65 or older and we still need “social distancing” of 65 or older, but total isolation in some regions for over 65 shouldn’t be a government type order, but rather a government “advise”. Monitoring such population should/could be a strict government order.
            The thing we call “lockdown” was for the purpose of flattening the curve, and as I said, “globally” this already happened.
            So to be clear, all population should be doing “social distancing” in regard to 65 or older and close monitoring of this population.
            So India should end their lockdown and put a lot more governmental attention upon it’s 65 + population. Same goes for Africa- probably as wild guess lots deficiency in some African countries in this regard. But globally there also deficency in that regard, which is “proven” by the high deaths per million.

            When leaving lock down, one of course should continue varying degrees of social distancing. And of course people infected, should not be in workplaces or crowded areas, includes anyone volunteering the possibility they might be infected with China virus. Don’t need a test that indicates this is the case. Should be “allowed” to self isolate. And this also extends to people worried about catching the virus. But such opinion or excuse [rather evidence} could change within say 1 month or less after ending the lockdown. But at any time, in future {say a few years} anyone should be able to get a test, and if results indicate they have virus- it extend another 2 weeks from when test was taken, that should go to work, etc.

          nate…”They dont have the slightest shred of scientific evidence to back that claim.

          But Gordon that meets your usual standards for believing a claim”.

          For one, I have stopped believing anything. For another, what is wrong with holding theories and propaganda to a scientific standard?

          When epidemiologist, Johan Geiseke, an advisor to the WHO, was asked his opinion on social distancing he replied immediately that no scientific evidence exists to support the theory.

        • barry says:

          That’s not what he said.

          As usual your regular net surfing has led you to the maverick voice, and that’s the one you think is right. Doesn’t matter what the vast majority of experts think, you just like mavericks – but only ones that suit your own opinions.

          But you can’t even get the maverick opinion right, you still have to distort what they say til its what you think and not what they think, just the same way you do with the NOAA advisory about the number of stations.

          This is demented, Robertson.

          Geiseke clearly thinks that social distancing and lockdowns prevent the spread of the disease – for that matter, this is true of most diseases, and is frankly bloody obvious. His opinion is that, except for aged care facilities, social distancing and lockdown merely suspend the inevitable and are mostly a waste of time.

          It’s not hard to get that right.

          My opinion – social distancing and lockdown were always designed to flatten the curve, and give time to prepare the health system for a potential explosion of cases, as we’ve seen in several countries around the world. No one seriously expected the disease to be eradicated enitrely, just managed.

          So I think Geiseke’s argument is a straw man from the outset. Medically sound, but missing the point.

      All of those people account for about 1/1000nds of 1% of populations. The problem is not the contagion its how utterly unprepared we have been for medical emergencies. We are too cheap to spend money on essentials, rather, we allow people like Bill Gates to amass billions of dollars then turn on us, telling us how stupid we are.

      Italy was the model for the hysteria and panic and it turns out many factors were missed due to the rush to panic. For one, the same devastation struck Italy in the 2016/17 flu season, where 25,000 people died across Italy. The difference this time it the contagion struck in a small northern area of Italy. In my region of Canada we’ve had about 120 deaths, most in senior’s care facilities.

      Furthermore, the city of Milan, in the middle of the current contagion, was declared the most polluted city in Europe in 2008. The same is true for Wuhan, China where the pollution is much greater. Therefore people are bound to have respiratory issues. Furthermore, Italy has some of the oldest population in the world.

      There is not much of a relationship between the two. The absolute temperature increase requires absolute temperatures and we seldom get to see those. Instead, we are inundated with a over-exaggerated and condensed anomaly view that fits within 1C.

      Anomalies are misleading since they are based on unnatural averages created by the human mind. They are also open to fudging as NOAA has shown by creating a trend from 1998 – 2012 that the IPCC failed to find in the papers it reviewed.

      I mean, how is the baseline range determined? It’s an arbitrary value related to the scientist creating it. Also, the practice of adjusting anomalies to seasonal averages is questionable.

      There is no way to find an accurate global average and even if we could, what does a 15C average mean in winter to people suffering through temps of -30C? We simply don’t have the coverage with land and ocean surface thermometers. Even with the sats, they average temperatures over altitude depths due to the nature of the telemetry. However, we know a lot about temperatures at altitudes and what to expect so in the capacity, the sat data is much more accurate.

    barry…”Youre going to have to do some selective editing, because the woman clearly believes HIV and AIDS are part and parcel. So your expert witness here will have terribly flawed judgement on the issue shes trained in according to your own beliefs, but miraculousy keen insight when it comes to padding out other bits of your opinion”.

    She would not have gotten a job working for Fauci had she not believed that nonsense about HIV/AIDS. I am not interested in that part of her revelations it is in her view as an immunologist that we are attacking the current contagion incorrectly.

    She was also right about Fauci albeit in the wrong context. Nobelist Kary Mullis did not refer to Fauci as an ****ole for nothing. Mullis did not tolerate fools and he became angered at the way Fauci promoted the HIV/AIDS theory with no scientific proof to back his claims.

    For at least the first ten years after HIV was declared as the cause of AIDS (no peer review) circa 1983 HIV was referred to as the virus BELIEVED to cause AIDS. The reason was simple, there was no scientific proof that it did. The theory was anointed under tremendous lobbying from the homosexual community who were demanding an answer.

    There has to be a reason why Fauci and Gallo have stubbornly clung to the THEORY that HIV causes AIDS while the scientist who was first to reveal the virus, Luc Montagnier, has long since changed his mind. He now claims HIV is harmless to a healthy immune system and the data over the past 40 years proves that clearly.

    I think this lady revealed in her video that Gallo and Fauci have profited from patents related to this theory. Mind you, Montagnier received half of Gallo’s patent profits on HIV tests after the French government protested to the US government that Gallo had stolen intellectual material from Montagnier. They apparently settled out of court with Montagnier receiving half the profits.

    Montagnier never did claim that HIV alone could cause AIDS, he thought a co-factor was required. It took him over 30 years to find the co-factor, life style. That’s a shame because the expert despised by Norman, Peter Duesberg, claimed that in the beginning.

    What Norman is missing is that Duesberg is a brilliant scientist who was the youngest member at the time ever inducted into the National Academy of Science. This is a case like that of Barry Marshall, the Australian who discovered that stomach ulcers are caused by a bacteria. It’s a case where one person is right and the rest are wrong.

    Mullis had mulled over the idea of finding a paper that proved how HIV caused AIDS but it was not till he was driving one night and heard Duesberg talking about HIV on the car radio that he was motivated to find that paper. He searched for 10 years, including a talk with Luc Montagnier, and could find none. Montagnier knew of no such paper.

    The lady in the video, an immunologist, is calling for an examination of the state of corruption in medical science. However, she has a steep, uphill battle. The mainstream press, butt-kissers to the medical establishment, are all over her already, cherry picking her words and focusing on trivia to discredit her.

    For example, they have zeroed in on a study she did circa 2008 that was apparently refuted. They mention nothing of Gallo’s abject failure trying to prove cancer is caused by a virus. Following that failure, with Gallo appearing as an absolute fool, the Reagan administration were looking for a cause of AIDS. There was Gallo, front and centre, with a very convenient viral theory.

    His viral theory was accepted without question and without peer review. Why don’t the mainstream press zero in on that?

      How can she give sound medical advice if she, who was in the lab in the thick of the HIV/AIDS research, got that issue completely wrong (according to you).

      And she believes that “nonsense” all right – she could have disavowed it in the vid, years after parting company from Fauci, instead of confirming the mainstream view.

      Nope, you just pick and choose without a shred of skeptical enquiry, any hearsay that satisfies your worldview.

    “He [Duesberg] isolated the first cancer gene through his work on retroviruses in 1970, and mapped the genetic structure of these viruses. This, and his subsequent work in the same field, resulted in his election to the National Academy of Sciences in 1986. He is also the recipient of a seven-year Outstanding Investigator Grant from the National Institutes of Health”.

    The blurb has omitted that Duesberg was the youngest member in 1986 ever inducted into NAS. Also, that he was the recipient of the California Scientist of the Year Award.

    If you were not so narrow minded, you’d research Duesberg and learn what an insightful, humanistic man he is. There is nothing evil about Peter Duesberg.

    The real evil exists with people who pump healthy people who have tested positive for HIV with lethal, toxic antiviral drugs. The drug manufacturers not only claim the drugs cannot cure HIV, they admit they are severely toxic and that they can cause IRS, essentially AIDS caused by drugs. The drugs are known to cause a serious blood disorder and liver/kidney failure, often leading to death.

    You are targeting the wrong man. Duesberg felt aghast when he learned AZT was being used to treat HIV. AZT is so toxic, it was discontinued as a cancer chemotherapy treatment. The newer HAART antivirals are little better.

    You should be going after Fauci, a man I consider as being truly evil.

      Peter Duesberg is a lying scoundrel that is responsible for causing the death of many people. A reporter revealed how he was a liar and deliberately distorting the Truth. The reporter was sued for defamation but the case did not stick as he had good research to back up his claims.

      https://www.courthousenews.com/aids-denialist-reporter-loses-defamation-claim/

      ” In an email to the one of the organizations coordinators, Treatment Action Group coordinator Richard Jeffreys wrote that Farber and Duesberg are not whistleblowers, they are simply liars who for many years have used fraud to argue for Duesbergs long-discredited theory that drug use and malnutrition not HIV cause AIDS.

        More:
        https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3015095/

        And then finally people who had HIV test positive but where part of the HIV causes AIDS denial group, here is some eye opening cases. You can reject them but Peter Duesberg is a bad person, a liar and deceiver. He may have done some good research at some time but now he likes the power and support of being praised for allegedly standing against the “Powers that Be”. I like that Spirit when it is honest and truthful. When it lies and is deceitful it is not something to be praised and should not be supported.

        When Duesberg first questioned the HIV connection to AIDS that is useful. It promotes good solid research. When he ignores mountains of evidence and then promotes his ideas in Africa leading to many deaths he is a bad person at that point. Nothing to admire at all.

      Perfect illustration of our polarized politics.

      When people disagree with you on politics or whatever, they are not just wrong.

      They do not just just have a different opinion. No, thats not enough.

      They must also be EVIL.

      Is it evil to push hard fund research into treatments for horrible diseases like AIDS?

      Is it evil to correct the president on science?

      If so, then evil must have been redefined.

        Except that nobody I am aware of correcting the President on science. In fact, I haven’t even heard the President offer anything even remotely like science. The President is by and large the skeptic-in-chief. Those who lose their skepticism aren’t scientists they are true believers.

        Evil is claiming somebody did when they didn’t.

    Gordon,

    From wikipedia:

    “Judy Anne Mikovits (c. 1958) is a discredited American ex-research scientist[2][3][10][11][12] who is known for her anti-vaccination activism,[12][13] promotion of conspiracy theories, and scientific misconduct.[6][7][8][9].”

    Look at all the references. Someone/s has done some research.

    Sciencemag has also taken an interest in her, with tons of references.

    https://www.sciencemag.org/news/2020/05/fact-checking-judy-mikovits-controversial-virologist-attacking-anthony-fauci-viral

    “…Two months later, the entire Science paper was retracted. Mikovits refused to sign the retraction notice, but she took part in another major replication effort. That $2.3 million study, led by Ian Lipkin of Columbia University and funded by the National Institutes of Health, was “the definitive answer,” Mikovits said at a September 2012 press conference where the results were announced. The rigorous study looked for XMRV in blinded blood samples from nearly 300 people, half of whom had the disease, and none had the virus. “There is no evidence that XMRV is a human pathogen,” Mikovits conceded….

    Mikovits has not published anything in the scientific literature since 2012. But she soon began to promote the XMRV hypothesis again, and attack the Lipkin study that she agreed had put the issue to rest. She has weighed in on the autism debate with controversial theories about causes and treatments. Her discredited work and her legal travails have made her a martyr in the eyes of some.”

    So I’ve got a new theory about you, Gordon, a nicer one.

    You are a sympathetic guy who takes in lonely opinions like stray dogs. You give them a home and lots of love, and take them on long walks down Blog Street. In a world that is cruel to loners and mavericks, you are their defender and champion.

  88. Eben says:

    The alarmists keep calculating the temperature to a hundreds of a degree over the last few years as some kind of proof there is something wrong with the climate. When in the history was it the temperature was always the same and not going up or down ???
    When looking at historical climate record it is totally obvious the temperature is constantly swinging up and down like a Jojo, of course you have to look at the real data not the highly smoothed out averaged charts the climate shysters put out for common lowest denominators. It always went up just before it turned down and always went down before it turned up , except until now when few rainmakers placed on the pedestal by politicians decided it will go only up and up into eternity unless you pay them millions dollars.
    The temperature rise of the past 50 or so years have its underlying causes laid down since 100 years before that because of the slow ocean overturning and Sun activity cycles and things like that.
    The climate wannabees who keep drawing straight line trends and projecting them in to the future as some kind of climate forecasting will almost always be wrong other than by some other unrelated coincidence.
    They will never identify the underlying causes of the upcoming flip over change, and they will never foresee the turning point.

    • barry says:

      Climate has always changed. Interannual variability in global temperature has always been there.

      No problem, right? You think ‘alarmists’ deny these things?

      These things can be true at the same time as acknowledging that the globe has been warming for the last 100 years or so, and that the primary cause since the mid 20th century is anthropogenic emissions of CO2, according to the best scientific understanding.

      Please no more straw men.

        Nothing at all scientific about that statement Barry.

        Define: “best”; quantify: “primary cause”. Those words have wide ranges of meaning. I tend to think even most skeptics acknowledge the warming that has been quantified to contain various amounts of “UHI”, “UHI sampling pollution”, “UHI estimation error”, “land use change”, “land use change measurement error”, “irrigation projects”, “irrigation project estimation error”, “weather station sampling error”, “weather station adjustment error”, “weather station measuring inconsistency”, “weather station instrumentation change error”, “weather station instrumentation change estimation error”,”weatheer station relocation error”, “compilation errors”, “compilation bias errors”, “compilation bias errors”, “interpolation error”, “kriging error”. I have probably only scratched the surface of sources of error above in trying to put together a list of potential error and how such errors can be increased through combinations of various types of error.

        Its especially tough when no transparent and enforced professional standards exist and when most efforts to test the results are performed by those who have openly expressed support for the original findings or are conflicted through receiving funding from the same sources as the original work with no direct liability exposure.

There is not possible discussion with you unless you become open minded and consider the very real possibility that most scientists are still honest researchers that are working hard to find the Truth. There are a few bad apples as with all fields. Most bad apples are the contrarians you believe preach Gospel Truth and are honest but the vast majority of research scientists are peddling lies for a paycheck. I have no clue what you do for a living, I am most certain it has nothing to do with any science field or research group. You don’t even appear scientifically literate. Your arguments are not even your original ideas. I can read most those on contrarian blogs. The peddle the notion that established science is false and they (the few) are the only ones with the Truth. Science illiterates like you eat the message with vigor. It makes you feel smart when you are not able to read a science textbook (above you intelligence level). You are in the cult of “US against the WORLD” and get a sense of superiority that the highly intelligent research scientists are phony so you don’t need to learn their brand of science, just listen to a few contrarians and you are set. Weird how you guys justify your lack of science knowledge and pretend to know what you are talking about. Nothing I can do will convince you. And you, with zero supporting evidence for you claims, will never convince me. If you want to convince me, gather good solid evidence that research scientists, in mass, are producing false and untrue data to support a paycheck.

            Actually thats pretty easy. Should be for you too if you had any experience in matters like this.

            I have strongly held this view since almost the first day I began research in this area because it was patently obvious to me and my professional experience. My reply to bdgwx above is in the same vein and I will give you the same reference.

            https://judithcurry.com/2013/09/20/co2-control-knob-fallacy/

            Its well understood by proponents of the theory that the authorities bestow rich rewards upon those who aid the political agenda who suucceed even partly in squelching doubt by altering history. Gores Hockey Stick exemplifies it and all those who have tried to find ways to make historic climate variation disappear. But you can’t make a fossil record disappear and in the natural sciences I am involved with the fossil record corresponds to natural climate variations on multi-decadal and longer time scales.

            I am concerned about the lack of explanations for such events as the Younger Dryas, 8.2k event, LIA, and more recent multi-decadal warming periods seen in the early 18th century and early 20th century.

            The hope to disappear all that and thus cool skepticism is more political than honest scientific inquiry. the whole purpose of which is to advance a very narrow viewpoint of climate change.

      • Ken says:

        • bdgwx says:

          How does declining solar activity after 1960 cause the Earth energy imbalance to increase to +0.6 W/m^2 despite an increase in aerosols that produce a negative radiative force?

            The top expert in that Dr. Richard Lindzen states that the net radiative forcing effect of aerosols is unknown.

          • bill hunter says:

            it doesnt make declining solar activity a warming force bdgwx.

            what is needed is some smarts and experience with really big systems to understand why.

            A recovery from the LIA requires and understanding of the behavior of large systems.

            Let me give you an example. Lets hypothesize that a change in solar output in 1700 produced a gross solar wattage output the equivalent of what is believed as prefeedback CO2 sensitivity that produces 1 deg C warming.

            The only difference here is that solar wattage increases perform differently than uniformly distributed forcings.

            So what do you get? Well you get 1/4the the rate of CO2 prefeedback
            and you get 1/2 a degree of uniform surface temperature feedback for the 3/4 degree warming we have seen in the modern era.

            But you also get 2 degrees of direct feedback from increased water vapor simply from evaporation of water during the well lit portions of the day.

            So we could be looking at essentially the same output from a smaller change in solar. I am not arguing this is true but follow along further.

            OK so we have the 2.75 degree warming as just a hypothesis. And lets say we have seen 1.25 degrees of it so far and solar declines some. What happens? Well if solar doesn’t decline by 2/3rds of the original increase it keeps warming. The lets say maybe we finally hit 2/3rds loss of the original increase in solar cycle 24. What happens? Well it needs about a decade to cool of the upper ocean

            Let’s discuss that scenario. I want to make sure I’m right about the following…

            1 unit of solar increase leads to 2.75C of warming.

            1/3 unit of solar increase leads to 1.25C of warming.

            …correct?

            If 1 unit of solar increase leads to 2.75C and if only 1.25C occurred at the point the solar increase dropped to say 1/2 of a unit then yes further warming would occur. It would not make it to 2.75C, but it would still be > 1.25C.

            However…and this is the crucial point…the warming would proceed at a slower rate and the energy imbalance on the planet would be lower than it was before.

            We observe the opposite happened. At about the same time solar output declined the warming rate and energy imbalance actually increased.

            But there is yet a 2nd way we can eliminate this scenario. That is the cooling stratosphere. If a brightening Sun were the cause of the warming then you would expect the stratosphere to warm. The only thing that can explain warming down low and cooling up high is a thermal barrier that has been placed between the two points.

            ——————–
            No! The target would be .92C which would be cooler than where the system was at the time the target changed by 2/3rds. The .92 is just a straight up climate sensitivity multiple based upon the original forcing. If that forcing reduced midway to ECS there would be a new ECS target.

            For a 1/3rd drop in solar activity the ECS target would be 1.83 so warming would continue albiet at a slower pace.

            For a 2/3rd drop in solar activity the ECS target would be .92 cooler than current. But TCR might be delayed somewhat and cooling not immediately obvious because of those up to 10 year ocean anomalies that has been accepted (range of 7 to 10 years) which prompted people to estimate warming in 10 year increments (step changes)

            All I was demonstrating is that simply because solar activity decreased its important to know by how much, what both TCR and ECS amount to, and continue to acknowledge the reason for step change predictions.

            However, the take home message with multi-decadal natural variation is you can throw out 10 year step changes and instead be looking at 3 to 10 decades instead as delays in warming or cooling. Throw in some of the bigger natural changes like YD, 8.2k, and LIA and you have a wide range of natural variation.

            If 1 unit of solar increase leads to 2.75C and if only 1.25C occurred at the point the solar increase dropped to say 1/2 of a unit then yes further warming would occur. It would not make it to 2.75C, but it would still be > 1.25C.

            that would only be a concern if you actually believed the climate was incapable of walking and chewing gum at the same time. the climate can be affected by long and short solar affects all creating perhaps variable cloud effects with in a saturated greenhouse environment and be affected by internal ocean current variations lsting anywhere from a few years to much longer. we would see only the sum of the effects on a thermometer

            aerosols are more of an excuse for model failures than anything else
            a bit of research will tell you little is known about them either their effects or their history.

            what that suggests is the models didn’t properly measure warming and no amount of debate or argument is going to fix the problem. Time to start over do the research on aerosols in a lab to better understand their effects, incorporate those effects in a model, run the model then watch he next 30 years or so and see if you finally got it right. But on the other hand by the time that got done doomsday will have come and gone a few more times. probably time to grow some balls and hang on tight for the ride.

            We know that aerosols in the stratosphere can make a big contribution, from successful modeling of volcanoes effect on global temp, like Pinatubo.

            They are part of the story, not an excuse.

            But, yes there are still some unknowns. Thats why people do science.

            Ive seen work on measurements of ‘dimming’ that occurred mid-late 20th century due to agricultural dust and pollution. Seems to have contributed to cooling.

            Not sure the dust has settled (ha!) on that one yet.

    barry…”Judy Anne Mikovits (c. 1958) is a discredited American ex-research scientist[2][3][10][11][12] who is known for her anti-vaccination activism,[12][13] promotion of conspiracy theories, and scientific misconduct.[6][7][8][9].”

    Once again, Barry, Wikipedia is not a reliable source of scientific information since anyone can post their views there. They claim she is discredited for one paper. Robert Gallo, who she mentions in her video, is a discredited scientists for claiming cancer is caused by a virus.

    They claim she is spreading propaganda and has participated in scientific misconduct, neither claim being backed by scientific evidence.

    I think you are an Australian, maybe my memory is frizzed. Anyway, Australian researcher Barry Marshall, had similar claims made against him when he claimed stomach ulcers were cause by a bacterium, heliobacter pylori. He was essentially laughed out of town and a paper he submitted was rejected. The journal editor not only rejected the paper, he commented that the paper was in the top ten of the worst papers ever submitted.

    Of course, Barry Marshall was right but he had to make himself extremely ill by drinking a concoction with the bacteria. He healed himself with antibiotic and only then was he taken seriously.

    I have tried to listen to this woman objectively looking for loopholes in her arguments. One I found is in her claim that HIV has been isolated which is not true. The scientist credited with discovering HIV claims he did not isolate HIV nor has he seen it with an electron microscope. I think what Judy is calling isolation is the same nonsense used today to infer a virus.

    I find her claims to be in the ballpark of science. She talks like a scientist, which she is, an immunologist. She gives pretty damning evidence against Fauci and his connection to the Wuhan, China labs. She gave a figure of the money exchanged between US sources and Wuhan.

    She has not spoken out again vaccinations, in fact, she claimed to support them. What she spoke out against was the prospect of a vaccine for the RNA-based viral infections. She claimed there is no vaccine for any since HIV. She is an immunologist and vaccines are part of her work. She fears a useless vaccine will be offered.

    She mentioned something important. The corona virus family comes from animals and she claimed any animal-based flu shot could contain corona virus. In Italy, preceding the covid outbreak, Italians had been given flu shots that contained the H1N1 virus. That convinced me never to get a flu shot again.

    She claimed to work with the US Army infectious disease control where they actually work creating bio-weapons and finding antidotes for chemical warfare. She claimed to have worked on the ebola virus and I know Kary Mullis did the same for the US Army with anthrax. Both were working on ways to moderate the effect of either infection. Mullis described the process as teaching the immune system to recognize an infection it had not learned to eliminate. He claimed to have succeeded with anthrax.

    Her claims about Fauci interfering in her attempt to publish a paper about HIV/AIDS rings true because there were shenanigans going on at the time with Gallo. She claims Fauci held up her paper to give Gallo the chance to lay a claim to credit him for finding the virus whereas it later came out that he had stolen intellectual property from Luc Montagnier, who discovered the virus.

    The French government complained to the US government over the theft and it was settled out of court. Gallo had claimed patents on the two HIV tests and Montagnier was awarded half the profits.

    She claimed Fauci has patents as well and he did not deny that, He claimed it was a requirement of his department that he file patents. Sure, Anthony, and I suppose you don’t get any money. She claimed those involved with covid vaccine patents stand to make billions.

    She claimed pharmaceutical companies are withholding medicines, suggesting sick people were more profitable. In Germany, Big Pharma tried to have vitamins banned. Big Pharma does not like healthy people. They took cellular nutritionist Matthias Rath to court for claiming illnesses could be treated with natural nutrients and the judge threw the case out, claiming there was no need to disbelieve the credentials of Rath and his claims.

    All in all, I am wondering why there is a rush on to discredit this woman. What’s the problem? I am more disturbed by the infringement on her right of free speech as guaranteed by the US constitution. She claims she was arrested without a warrant and held without charges.

    She has been forbidden to pursue her case in court. What kind of country has the US become? Either charge the woman so she can defend herself or leave her alone.

      Barry’s earlier comments and mine were advanced further by your post.

      The point is, she makes a statement. Thats her version of events. It happens to align well with your conspiratorial thinking.

      Therefore her statement is accepted as fact.

      Problem is, in court, it would not be accepted as fact. Because a number of others could testify that here statement is false. As I noted above.

      But you guys still accept it as fact.

      In addition, in court, her history of deception could be brought out to show she lacks credibility.

      She asserts that she was fired and arrested to keep her silent on warning about an XMRV virus that causes Autism and CFS and is in vaccines.

      That all sounds great to anti-vaxxers and conspiracy minded and Fauci haters, but none of it is true.

      Her own research on that particular virus was proven wrong and retracted.

      She participated in the multi-lab effort to replicate the work, and in the end SHE ADMITTED that is was wrong and that there was no evidence linking it to CFS, as you can see in this video of her at a conference. https://www.youtube.com/watch?v=CVu-lGSnGC0

      The large scale effort to replicate her work on XMRV were encouraged by Fauci. She claimed Fauci sent an email to her boss threatening her arrest. No such email exists.

      There is no evidence of XMRV in vaccines, pure speculation.

      There is no evidence linking XMRV to Autism. Made up.

      She was arrested for stealing lab notebooks from her former employer. There was a valid search warrant. She was charged. A co-worker admitted assisting her. Another co-worker admitted she was asked to help her. She returned the material and the charges were dropped.

      In the 80s she did work related to HIV and AIDS. She clearly understands that AIDS is caused by HIV.

      It’s interesting that you are certain she is lying about HIV.
      But still, you believe everything else she says about Fauci and vaccines and conspiracies and COVID..

        *****

        Your theory sounds fine on the face of it but she cannot get to court, or even discuss her case, because she is under a gag order of some kind. Why would anyone go to such lengths to silence a person? What secrets are they trying to withhold at NIAID?

        You can claim conspiratorial thinking all you want, but I have been following the facts of this nonsense for at least 20 years. I weighed all the facts initially which were essentially as follows:

        1)we have a new virus (HIV) which acts as no other virus has ever acted and is able to go dormant in an infected person for some 15 – 20 years before awakening and suddenly destroying an immune system.

        -The virus is out-numbered something like 800 to one by immune systems cells yet it manages to overwhelm them.

        -The 30 opportunistic infections collectively known as AIDS can become active when HIV destroys the immune system. One of those OFs is tuberculosis. If you have TB they have a treatment to heal it. If you have TB and are HIV positive they give you toxic antivirals that can kill you or even cause AIDS (IRS).

        2)no virus known as HIV has ever been isolated, purified, or seen with an electron microscope. The founder of the virus, Luc Montagnier, has admitted he INFERRED a virus based on RNA found in a person with AIDS.

        -Duesberg, an expert in retroviruses, who isolated the first cancer gene and mapped its DNA, was inducted into the National Academy of Science for his work. He claimed HIV could not possibly overwhelm a healthy immune system.

        -Duesberg pointed out, at the time, circa 1983, that AIDS in North America involved mainly male homosexuals and no known virus could attack only males. He claimed the obvious, that the men in question were gathering in steam baths in New York and San Francisco and having sex with multiple partners while consuming up to 6 designer drugs including cocaine and amyl nitrate.

        Duesberg claimed it was life style causing AIDS, not a virus. Nearly 40 years alter, Luc Montagnier, who discovered HIV, is claiming the same thing, that HIV is harmless to a healthy immune system. The difference is, Duesberg lost his career while Montagnier, a Nobelist, has thrived. Why has no one apologized to Duesberg for wrecking his life?

        They are doing exactly the same thing to this lady as they did to Duesberg. She is right, science is corrupt.

        -the primary AIDS opportunistic infections infecting those men were Kaposi’s Sarcoma and Pneumocystitis pneumonia.Kaposi’s sarcoma is a skin cancer known to be caused by the herpes virus, which is also related to a high risk lifestyle. In other words, it does not affect people in monogamous relationships, either heterosexual or homosexual.

        -pneumocystitis pneumonia is caused by fungus called Pneumocystis jirovecii. Nobelist Kary Mullis pointed out the obvious. If you hang around in steam baths with anal bacteria being transmitted by the steam and/or inhale amyl nitrate, you are likely to get a fungal lung infection.

        **********

        Come on Nate, this is a no-brainer. Only 16% of male homosexuals get AIDS and they are the ones who practice this kind of high risk behavior.

        This is a case of the Emperor walking around naked and no one having the guts to mention it. Duesberg and Mullis mentioned the obvious and it cost Duesberg his career. As Mullis used to joke, they can’t touch him because he’s a Nobelist.

          Except, on the fact that HIV is the cause of AIDs, she would say you are full of crap.

          She would know, she researched it, and you did not.

          Is she truthful about that?

          Not that, but you believe she is truthful about everything else, because it does align with your conspiratorial beliefs?

        • Nate says:

          “Come on Nate, this is a no-brainer. Only 16% of male homosexuals get AIDS and they are the ones who practice this kind of high risk behavior.”

          The virus is well known to be transmitted sexually or through blood transfusions. If high risk means no condom then of course HIV transfer is more likley.

          When HIV infected people suddenly stopped dying after they began taking the anti-HIV cocktail…c’mon THAT is a no-brainer that takes real effort to deny.

          The ant-viral therapy demonstrably works. It prevented deaths of hundreds of thousands. In medical science, this is about as definitive as it ever gets.

          And ive repeatedly asked you to show evidence that it doesnt work.

        Gordon,

        “You can claim conspiratorial thinking all you want, but I have been following the facts of this nonsense for at least 20 years…”

        You procced to talk about HIV and AIDS, which are completely irrelevant to the veracity of Mikovits claims.

        You connect Mikovits claims to your conspiracy beliefs about HIV/AIDS, even though your star witness has views quite different from you on that subject. Even though the HIV/AIDS conspiracy you hold is completely irrelevant to whether her version of events is true or not.

        This is what conspiracy theorists do, link similar sounding stuff together to bolster their conspiracy ideation, creating patterns of thought, even though the loose links don’t have any real traction.

        If there is evidence that the links don’t hold? Trash that evidence. Information that works to undo the conspiracy theory? It’s part of the smokescreen supporting the hoax.

        These tactics make the conspiracy ideation self-fulfilling. True skepticism is the cure for this.

        So instead of you saying the Mikovits is being “discredited” in science articles, you would actually read them neurtrally, follow the links and THEN judge if the criticism has merit.

        But you don’t do that, Gordon. And it’s obvious you don’t. You would otherwise talk specfifically about the criticism instead of panning it in one generalized statement. This is not remotely skeptical of you.

      • Gordon Robertson says:

        nate…”This article in Science fact-checks the claims in her video”.

        This is not a fact check, it’s an attempt to discredit.

        In one part they mention Gallo in a good light re his contribution to the discovery of HIV. They failed to reveal that he was charged by Montagnier of stealing his work and when the French government complained to the US government and out of court settlement was reached. Gallo, who took out patents on both HIV tests was forced to split the profits with Montagnier.

        I have seen this nonsense before in defence of a paradigm. It’s deja vu based on the arguments put forth against Duesberg and they were all wrong. Duesberg has been vindicated, albeit too late.
