Amazing Video of Rochelle, IL Tornado Yesterday

April 10th, 2015

Storm chasers captured over 6 minutes of amazing footage of the EF3 or EF4 tornado that killed one person and caused extensive damage in Fairdale, Illinois (northeast of Rochelle, southeast of Rockford) yesterday. This is one of the best tornado videos I have ever seen.

For those hearing this was a global warming-fueled tornado, here’s my post from 4 years ago explaining why more tornado activity typically requires an unseasonably cool airmass.

If warm, moist air was the missing ingredient, the tropics would be filled with tornadoes.

And if you are wondering, “Well, couldn’t more warm, moist air next to a cool air mass enhance tornado formation?” Well, yes, except the equator-to-pole temperature contrast has decreased during warming, not increased. In other words, the cool air masses have warmed more than the warm airmasses, reducing the available energy for these types of storms.

It’s just weather, folks. Global warming didn’t cause your tornado, and it didn’t cause your daughter’s asthma.

Has The Guardian “Rolling Stoned” Christy & Spencer?

April 7th, 2015

That tireless ecological zealot over at The Guardian, Dana Nuccitelli, took the opportunity of our 25th anniversary of satellite-based global temperature monitoring to rip us a new one.

Comparing John Christy and me to “scientists who disputed the links between smoking and cancer”, Dana once again demonstrates his dedication to the highest standards of journalism.

Well done, Grauniad.

I prefer to compare us to Barry Marshall and Robin Warren, who rejected the scientific consensus that peptic ulcers were due to too much stress or spicy food. While they eventually received the Nobel Prize after years of ridicule and scorn from the medical research community, we have no illusions that we will ever be credited for our long-standing position that global warming fears have been overblown. I’m sure the UN’s IPCC will find a way to take credit for that, and get another Peace Prize for it.

(I wonder if Marshall and Warren were being paid off by the spicy food lobby?)

The “97% of all climate scientists agree“ meme that Dana bitterly clings to has been thoroughly discredited…. as if scientific consensus on something so poorly understood as climate change (or stomach ulcers 15 years ago?) really means anything, anyway.

To prove that Dana should probably avoid trying to interpret simple graphs, let’s examine this chart he so likes, which allegedly shows that our (UAH) global temperature dataset has been continually adjusted for errors over the years, resulting in an increasing warming trend:

Danas-excellent-chart

Now, setting aside the fact that (1) we actually do adjust for obvious, demonstrable errors as soon as they have been found (unlike the IPCC climate modelers who continue to promote demonstrably wrong models), and (2) RSS gets about the same (relatively benign) warming trend as we do, let’s examine some other popular temperature datasets in the same manner as the above graph:

Accum_Trend

Looks a lot like Dana’s plot, doesn’t it?

Do you want to know why? Is it really because all those other temperature dataset providers were also busily correcting mistakes in their data, too?

No, it’s largely because as the years go by, the global temperature trend changes, silly.

About the only thing Dana got reasonably correct is his article’s tag line, “John Christy and Roy Spencer are pro-fossil fuel and anti-scientific consensus.”

You’re damn right we are. But not because we are paid to say it, which we aren’t. (What are you paid to say for The Guardian, Dana?)

We are pro-fossil fuel because there are no large scale replacements available, wind and solar are too expensive, and you can’t just cut fossil fuel use without causing immense human suffering. Yes, I’ve talked to some of the top economists about it.

And indeed we are “anti-scientific consensus” because the consensus (which mostly just follows the average of the IPCC climate models) has been demonstrated to be wrong.

Finally, if Dana objects to me tiring of being called a “global warming denier” (with the obvious Holocaust connotations) for the last seven eight years and fighting back, read this and then tell me where I am wrong.

Answering Ron Bailey’s Question: “What Evidence Would Persuade You That Man-Made Climate Change Is Real?”

April 6th, 2015

I just found out that Ron Bailey at Reason.com published an article a few days ago entitled, “What Evidence Would Persuade You That Man-Made Climate Change Is Real?

I’ve spent some time with Ron, and he is a very sharp guy. That’s why I’m a little disappointed that he would publish this mixture of straw man arguments and uncritical thinking. He is the only deep thinker I know of who switched from being a skeptic about the causes of global warming to a believer…an epiphany which occurred in 2005, according to the article. (Hmmm…I wonder if he was fooled by all those major hurricanes that hit the U.S. that year? It’s now almost 10 years later, and we haven’t had one since.)

The first problem I have is with his premise: that skeptics believe humans have no role in climate change. I don’t know of any serious skeptics who hold such a view. Now, maybe he is addressing people who deny any human involvement in global warming. His article is vague, and maybe he can clarify his intent for us.

The second problem I have is with Ron’s list of a variety of evidences of global-average warming, which (again) no skeptic worth their salt disputes. The science dispute is over how much of the warming is manmade versus natural. Like too many others, Ron conflates climate change with human-caused climate change, which are not the same thing.

Regarding his list, he seems to believe they are independent evidences of manmade warming. Wrong. To the extent warming occurs, even if it is entirely natural, warming would occur in the atmosphere and deep ocean; it would cause an increase in atmospheric water vapor, as well as precipitation; the warming would be stronger in the upper troposphere than the lower troposphere; and stronger over land than over the ocean.

These things would all occur together anyway, no matter the cause of the warming, Ron. And causation is, indeed, the question which science so far cannot answer.

Since climate models cannot even hindcast what has happened (let alone forecast), they clearly have no handle on multi-decadal temperature changes brought about by natural effects. There does not even need to be any forcing — e.g. the sun, volcanoes, etc. — in order for climate to change because the ocean-atmosphere system is nonlinear and dynamical — in a word, chaotic. It can change all by itself. For example, it this plot we see that global warming (and cooling) has been the rule, not the exception, for the last 2,000 years:

Ljungqvist-2000-yrs-temp-reconstruction

If the above graph is anywhere close to what has actually happened, then most centuries have experienced global warming or cooling. So, what would it take to predict global warming (along with all of the correlated changes, listed above) due to any cause you’d like to invoke?

Basically, all it takes is a flip of a coin.

If you wonder, how could so many scientists be wrong? Well, the medical community had millions of peptic ulcers to study, and it took decades (and two brave Australian researchers) to finally convince them of a bacterial basis for ulcers.

The Earth, in contrast, is a single subject, and we can’t easily or quickly test its response to various treatments. It would be very easy for group think to dominate the scientific community, especially when continued funding depends on a continued climate crisis.

A third problem I have with Ron’s article: he uses “falsifiable predictions” of the future as evidence supporting his case! Really? Well, we’ve already had abundant predictions of what would happen by now from modelers like James Hansen that have turned out to be wrong. There you go, skeptics have real falsified predictions they can point to….not predictions of what might happen 10 years from now.

Why didn’t he mention the recent increase in papers (our APJAS paper included) with evidence that recent warming has been partly natural? Yes, as he says, natural variability can work both ways (warming OR cooling), but the available evidence is that recent warming was partly due to nature. Significantly, that warming occurred during the period when climate modelers developed their models, and since they assumed all warming was manmade, they had to increase the models’ sensitivity. Now, they are between a rock and a hard place, continuing to publish overly-sensitivity models they know are wrong (based upon both surface AND deep ocean warming rates).

Such a travesty would never be allowed in a hard discipline that uses physics, like engineering. An impartial judge with any cajones wouldn’t even allow climate models as evidence in a court of law since they have, so far, largely failed in their predictions.

Does Ron know that the deep-ocean warming since the 1950s is so weak (if it is even real from an observational error perspective) that it represents only a 1 part in 1,000 imbalance between incoming and outgoing energy? Do we really believe that chaotic changes in the circulations of the ocean and atmosphere cannot create such a tiny imbalance? The above graph (along with historical evidence of the Little Ice Age and Medieval Warm Period) suggests such small changes are fairly routine.

So, Ron asks what evidence would convince me that recent warm was manmade? Well, how about knowledge of how much natural climate change would have occurred without human influence? Then we would know the remainder was human-induced. Except, there is no way to know the natural component. If there was, climate models would have reasonably replicated the temperature changes since the 1950s rather than looking like a bowl of spaghetti.

And since I already believe manmade climate change (to some non-zero extent) is real, maybe I can ask Ron: What evidence would persuade you that your original question is nothing more than a straw man argument?

I hate to impute motives, but I really have to wonder if he is succumbing to peer pressure, since believing anything that smacks of denial-ism is really frowned upon in the intellectual circles I’m sure Ron is part of.

Yes, I believe that adding CO2 to the atmosphere has probably caused some warming, even though there is no way to prove it. Just how much human-caused warming is the question. And, as Ron correctly notes, it says nothing about what if anything should (or even can) be done about it anyway.

Global Temperature Update for March, 2015: +0.26 deg. C

25th Anniversary of Global Satellite Temperature Monitoring

April 1st, 2015

Sunday marked the 25th anniversary of John Christy and I announcing the new technique for monitoring global temperatures with satellites. We had no idea the methodology would end up being central to the global warming wars. It’s been a wild ride since then.

A story today by Paul Gattis at AL.com has the details:

The silver anniversary of Roy Spencer’s career-defining moment arrived with no expectation in March. He didn’t realize it until someone mentioned it to him.

For John Christy, he had no idea that a discovery announced in 1990 would not only still resonate 25 years later but would be at the center of a raging debate.

The date was March 29, 1990. That was the day – though unbeknownst to either Christy or Spencer – they publicly became climate change skeptics.” ..the rest of the story here.

White House Declares April “Earth Month”

April 1st, 2015

EH_switchAfter Saturday night’s unprecedented success with Earth Hour, the White House announced today that, by Executive Order, April has been declared “Earth Month”, the next step in reducing our dependence on fossil fuels.

For the month of April, U.S. residents and businesses are being required to turn off all electrical appliances and lights. A special waiver is being given to electric cars and homes running entirely on solar-powered electricity. Compliance will be monitored by volunteers who report infractions to a special EPA hotline.

White House press secretary Josh Earnestly stated, “The President’s science advisor has informed us that the resulting reduction in greenhouse gas emissions, especially from coal-fired power plants, will be the same as taking 92 billion cars off the road for 15 years.”

While hospitals will be inconvenienced as life-saving equipment is shut down, economist Paul Krugman has stated that there will be a significant savings in the health care sector as fewer and fewer patients will eventually be requiring such services. “The U.S. population will, on average, be healthier at the end of the month”, Krugman said.

When asked how the country can function without using electricity, Josh Earnestly replied, “If North Korea can do it, so can we.” Repeated attempts to reach North Korean leader Kim Jong Un for comment were unsuccessful.

This is Your President’s Science Advisor

March 21st, 2015

A President’s political appointees are chosen because their views support the President’s political leanings. This is to be expected.

One might expect the Science Advisor position to be more politics-free, but not these days. The President’s choice of John Holdren, previously a professor at Berkley, to be his science advisor tells us something about his policies.

Holdren wrote this 1975 newspaper article, entitled Too Much Energy, Too Soon, a Hazard, about the dangers of having too much energy available for human use.

Among some of the gems of wisdom there, we find this:

Finally, less energy can mean more employment. The energy producing industries comprise the most capital intensive and least labour intensive major sector of the economy. Accordingly, each dollar of investment capital taken out of energy production and invested in something else, and each personal consumption dollar saved by reduced energy use and spent elsewhere in the economy will create more jobs than are lost.

Now, one doesn’t need to be an economist to see the problem with this position. Holdren thinks that because the energy sector generates so much energy so efficiently with so few people and with so much capital investment, that must be a bad thing. He is either unaware (he can’t be that stupid) or he chooses to hide the fact that all of that energy is demanded by the rest of the country for everything we do. Energy enables people to make things and provide services.

As I’ve said before (and I’ve asked some of the nation’s top economists about the validity of my views), if you really want full employment, just put everyone to work digging holes in the ground and filling them up again. Just having “jobs” is not the desired goal; what we do in those jobs makes all the difference. Jobs must efficiently provide goods or services desired by the rest of society in order for everyone, poor and rich alike, to prosper.

And abundant, affordable energy is required for all of those productive jobs.

It literally scares me that people like this have so much influence in our country.

Color Satellite View of Solar Eclipse

March 20th, 2015

Here’s a NASA MODIS view of this morning’s solar eclipse from the Terra polar-orbiting satellite. Terra takes a “snapshot” as it passes over every ~100 minutes, and this montage shows three successive orbits, with the second orbit capturing the effect of the eclipse on the solar illumination of the landscape and clouds. Note the distinctive difference in color (click image for full-size):

Bring Back Our Tornadoes!

March 19th, 2015

bring-back-our-tornadoes
One of the many tragic consequences of human-caused climate change is the nearly unprecedented lack of tornadoes during the first half of March.

According to Greg Forbes, severe weather weenie at The Weather Channel, the only other year when this happened was 1969.

Clearly, this is just one more example of how we are destroying the climate system.

Atlas Shrugged, Net Neutrality, and Government Controlled Science

March 19th, 2015

The Ministry of Truth: Where all climate science will be controlled for the public good.

The Ministry of Truth: Where all climate science will be controlled for the public good.

There’s an amazing article by Robert Tracinski at TheFederalist.com which draws powerful parallels between Ayn Rand’s Atlas Shrugged and what we are seeing today with increasing government regulation.

It uses the latest Net Neutrality push and government attempts to shut down private funding of climate science as just the latest examples of a trend which is destroying competition… and ultimately prosperity. Crony capitalist elements of big business trying to seek competitive advantage by encouraging the government regulation end up finding themselves beholden to their government masters as a result.

I know this is all nothing new…I was just a little taken aback to realize that those of us who are skeptical of assertions there’s a “climate crisis” in need of government intervention and control are now players in the game, as a few in Congress try to intimidate us.

Al Gore has just announced the need to punish climate-change deniers…as if anyone denies that climate changes. Sheesh. Even we admit that humans have some influence on climate. But (1) the human portion is highly uncertain, and (2) we can’t do anything significant about it anyway without killing millions of people in the process.

Meanwhile, the mainstream media dutifully allows such perverted reframing of the terms of the debate to go unchallenged. Here’s John Christy’s response to that intimidation, published yesterday.

The Federalist article is well worth the read, especially for those familiar with Atlas Shrugged.
