James Hansen's Former NASA Supervisor Declares Himself a Skeptic – Says, Hansen 'Embarrassed NASA', 'Was Never Muzzled', & Models 'Useless'


nasa_logoUPDATE 1/28: Full text of Dr. Theon’s letter has been post on the Senate website and below.

This is something I thought I’d never see. This press release today is from the Senate EPW blog of Jame Inhofe. The scientist making the claims in the headline, Dr. John S. Theon, formerly of the Institute for Global Environmental Strategies, Arlington, Virginia, has a paper here in the AMS BAMS that you may also find interesting. Other papers are available here in Google Scholar. He also worked on the report of the Space Shuttle Challenger accident report and according to that document was a significant contributor to weather forecasting improvements:

The Space Shuttle Weather Forecasting Advisory Panel, chaired by Dr. John Theon, was established by NASA Headquarters to review existing weather support capabilities and plans and to recommend a course of action to the NSTS Program. Included on the panel were representatives from NASA, the National Oceanic and Atmospheric Administration (NOAA), the Air Force, and the National Center for Atmospheric Research.

For those just joining the climate discussion, Dr. James Hansen is the chief climate scientist at NASA Goddard Institute for Space Studies (GISS) and is the man who originally raised the alarm on global warming in 1988 in an appearance before congress. He is also the keeper of the most often cited climate data.

EPW press release below – Anthony
Washington DC, Jan 27th 2009: NASA warming scientist James Hansen, one of former Vice-President Al Gore’s closest allies in the promotion of man-made global warming fears, is being publicly rebuked by his former supervisor at NASA.

Retired senior NASA atmospheric scientist, Dr. John S. Theon, the former supervisor of James Hansen, NASA’s vocal man-made global warming fear soothsayer, has now publicly declared himself a skeptic and declared that Hansen “embarrassed NASA” with his alarming climate claims and said Hansen was “was never muzzled.” Theon joins the rapidly growing ranks of international scientists abandoning the promotion of man-made global warming fears.

“I appreciate the opportunity to add my name to those who disagree that global warming is man made,” Theon wrote to the Minority Office at the Environment and Public Works Committee on January 15, 2009. “I was, in effect, Hansen’s supervisor because I had to justify his funding, allocate his resources, and evaluate his results,” Theon, the former Chief of the Climate Processes Research Program at NASA Headquarters and former Chief of the Atmospheric Dynamics & Radiation Branch explained.

“Hansen was never muzzled even though he violated NASA’s official agency position on climate forecasting (i.e., we did not know enough to forecast climate change or mankind’s effect on it). Hansen thus embarrassed NASA by coming out with his claims of global warming in 1988 in his testimony before Congress,” Theon wrote. [Note: NASA scientist James Hansen has created worldwide media frenzy with his dire climate warning, his call for trials against those who dissent against man-made global warming fear, and his claims that he was allegedly muzzled by the Bush administration despite doing 1,400 on-the-job media interviews! – See: Don’t Panic Over Predictions of Climate Doom – Get the Facts on James Hansen – UK Register: Veteran climate scientist says ‘lock up the oil men’ – June 23, 2008 & UK Guardian: NASA scientist calls for putting oil firm chiefs on trial for ‘high crimes against humanity’ for spreading doubt about man-made global warming – June 23, 2008 ]

Theon declared “climate models are useless.” “My own belief concerning anthropogenic climate change is that the models do not realistically simulate the climate system because there are many very important sub-grid scale processes that the models either replicate poorly or completely omit,” Theon explained. “Furthermore, some scientists have manipulated the observed data to justify their model results. In doing so, they neither explain what they have modified in the observations, nor explain how they did it. They have resisted making their work transparent so that it can be replicated independently by other scientists. This is clearly contrary to how science should be done. Thus there is no rational justification for using climate model forecasts to determine public policy,” he added.

“As Chief of several of NASA Headquarters’ programs (1982-94), an SES position, I was responsible for all weather and climate research in the entire agency, including the research work by James Hansen, Roy Spencer, Joanne Simpson, and several hundred other scientists at NASA field centers, in academia, and in the private sector who worked on climate research,” Theon wrote of his career. “This required a thorough understanding of the state of the science. I have kept up with climate science since retiring by reading books and journal articles,” Theon added. (LINK) Theon also co-authored the book “Advances in Remote Sensing Retrieval Methods.” [Note: Theon joins many current and former NASA scientists in dissenting from man-made climate fears. A small sampling includes: Aerospace engineer and physicist Dr. Michael Griffin, the former top administrator of NASA, Atmospheric Scientist Dr. Joanne Simpson, the first woman in the world to receive a PhD in meteorology, and formerly of NASA, Geophysicist Dr. Phil Chapman, an astronautical engineer and former NASA astronaut, Award-Winning NASA Astronaut/Geologist and Moonwalker Jack Schmitt, Award-winning NASA Astronaut and Physicist Walter Cunningham of NASA’s Apollo 7, Chemist and Nuclear Engineer Robert DeFayette was formerly with NASA’s Plum Brook Reactor, Hungarian Ferenc Miskolczi, an atmospheric physicist with 30 years of experience and a former researcher with NASA’s Ames Research Center, Climatologist Dr. John Christy, Climatologist Dr. Roy W. Spencer, Atmospheric Scientist Ross Hays of NASA’s Columbia Scientific Balloon Facility]

Gore faces a much different scientific climate in 2009 than the one he faced in 2006 when his film “An Inconvenient Truth” was released. According to satellite data, the Earth has cooled since Gore’s film was released, Antarctic sea ice extent has grown to record levels, sea level rise has slowed, ocean temperatures have failed to warm, and more and more scientists have publicly declared their dissent from man-made climate fears as peer-reviewed studies continue to man-made counter warming fears. [See: Peer-Reviewed Study challenges ‘notion that human emissions are responsible for global warming’ & New Peer-Reviewed Scientific Studies Chill Global Warming Fears ]

“Vice President Gore and the other promoters of man-made climate fears endless claims that the “debate is over” appear to be ignoring scientific reality,” Senator James Inhofe, Ranking Member of the Environment & Public Works Committee.

A U.S. Senate Minority Report released in December 2008 details over 650 international scientists who are dissenting from man-made global warming fears promoted by the UN and yourself. Many of the scientists profiled are former UN IPCC scientists and former believers in man-made climate change that have reversed their views in recent years. The report continues to grow almost daily. We have just received a request from an Italian scientist, and a Czech scientist to join the 650 dissenting scientists report. A chemist from the U.S. Naval Academy is about to be added, and more Japanese scientists are dissenting. Finally, many more meteorologists will be added and another former UN IPCC scientist is about to be included. These scientists are openly rebelling against the climate orthodoxy promoted by Gore and the UN IPCC.

The prestigious International Geological Congress, dubbed the geologists’ equivalent of the Olympic Games, was held in Norway in August 2008 and prominently featured the voices of scientists skeptical of man-made global warming fears. Reports from the conference found that Skeptical scientists overwhelmed the meeting, with ‘2/3 of presenters and question-askers hostile to, even dismissive of, the UN IPCC’ ( See full reports here & here ] In addition, a 2008 canvass of more than 51,000 Canadian scientists revealed 68% disagree that global warming science is “settled.” A November 25, 2008, article in Politico noted that a “growing accumulation” of science is challenging warming fears, and added that the “science behind global warming may still be too shaky to warrant cap-and-trade legislation.” More evidence that the global warming fear machine is breaking down. Russian scientists “rejected the very idea that carbon dioxide may be responsible for global warming”. An American Physical Society editor conceded that a “considerable presence” of scientific skeptics exists. An International team of scientists countered the UN IPCC, declaring: “Nature, Not Human Activity, Rules the Climate”. India Issued a report challenging global warming fears. International Scientists demanded the UN IPCC “be called to account and cease its deceptive practices.”

The scientists and peer-reviewed studies countering climate claims are the key reason that the U.S. public has grown ever more skeptical of man-made climate doom predictions. [See: Global warming ranks dead last, 20 out of 20 in new Pew survey. Pew Survey: & Survey finds majority of U.S. Voters – ‘51% – now believe that humans are not the predominant cause of climate change’ – January 20, 2009 – Rasmussen Reports ]

The chorus of skeptical scientific voices grow louder in 2008 as a steady stream of peer-reviewed studies, analyses, real world data and inconvenient developments challenged the UN’s and former Vice President Al Gore’s claims that the “science is settled” and there is a “consensus.”

On a range of issues, 2008 proved to be challenging for the promoters of man-made climate fears. Promoters of anthropogenic warming fears endured the following: Global temperatures failing to warm; Peer-reviewed studies predicting a continued lack of warming; a failed attempt to revive the discredited “Hockey Stick“; inconvenient developments and studies regarding rising CO2; the Spotless Sun; Clouds; Antarctica; the Arctic; Greenland’s ice; Mount Kilimanjaro; Global sea ice; Causes of Hurricanes; Extreme Storms; Extinctions; Floods; Droughts; Ocean Acidification; Polar Bears; Extreme weather deaths; Frogs; lack of atmospheric dust; Malaria; the failure of oceans to warm and rise as predicted.

Indeed it is.
And it shows how the myth has desperately been kept alive ever since Hanson was discredited.
The debunking is not by some so-called "skeptic".
But by a leading scientist who exposed him.
He joins many other leading scientists around the world who question the validity of the C02 claims.
This also puts paid to the IPCC claims that they have consensus.
And more particularly their other claim that "the science is settled."

Thirty Years On, How Well Do Global Warming Predictions Stand Up?
2 days ago June 22, 2018

The short answer, is not all that well.


On June 23, 1988, NASA scientist James E. Hansen testified before the Senate Committee on Energy and Natural Resources, where he expressed his “high degree of confidence” in “a cause-and-effect relationship between the claimed CO2 induced “greenhouse effect and observed warming.”

The 30th anniversary of Mr. Hansen’s predictions affords an opportunity to see how well his forecasts have turned out.

In an article in the Wall Street Journal today, climatologist Dr Patrick Michaels and meteorologist Dr. Ryan Maue compare Hansen’s predictions to actual reality over the past 30 years. Instead of the gloom and doom we heard in 1988, we have an earth that is only moderately warmer.

Hansen’s fabulously wrong 1988 climate model.

Here’s some excerpts from the article by climatologist Dr. Pat Michaels and meteorologist Dr. Ryan Maue:

“Thirty years of data have been collected since Mr. Hansen outlined his scenarios—enough to determine which was closest to reality. And the winner is Scenario C. Global surface temperature has not increased significantly since 2000, discounting the larger-than-usual El Niño of 2015-16. Assessed by Mr. Hansen’s model, surface temperatures are behaving as if we had capped 18 years ago the carbon-dioxide emissions responsible for the enhanced greenhouse effect. But we didn’t. And it isn’t just Mr. Hansen who got it wrong. Models devised by the United Nations Intergovernmental Panel on Climate Change have, on average, predicted about twice as much warming as has been observed since global satellite temperature monitoring began 40 years ago…”

“Several more of Mr. Hansen’s predictions can now be judged by history. Have hurricanes gotten stronger, as Mr. Hansen predicted in a 2016 study? No. Satellite data from 1970 onward shows no evidence of this in relation to global surface temperature. Have storms caused increasing amounts of damage in the U.S.? Data from the National Oceanic and Atmospheric Administration show no such increase in damage, measured as a percentage of gross domestic product. How about stronger tornadoes? The opposite may be true, as NOAA data offers some evidence of a decline. The list of what didn’t happen is long and tedious.”

It turns out that global surface temperature has not increased significantly since 2000, discounting the larger-than-usual El Niño of 2015-16.

And it isn’t just Hansen who got it wrong, models devised by the IPCC have, on average, predicted about twice as much warming as has been observed since global satellite temperature monitoring began 40 years ago.

What about Hansen’s other claims? He claimed that the late ’80s and ’90s would see “greater than average warming in the southeast U.S. and the Midwest.” No such spike has been measured in these regions.

In 2007, Hansen stated that most of Greenland’s ice would soon melt, raising sea levels 23 feet over the next 100 years. Subsequent research published in Nature magazine demonstrated this to be impossible.

Several more of Mr. Hansen’s predictions fizzled. Have hurricanes gotten stronger, as Mr. Hansen predicted? No.

Satellite data shows no evidence of this in relation to global surface temperature.

Have storms caused increasing damage in the U.S.?

No. Data from NOAA show no such increase.

How about stronger tornadoes?

No. In fact, the opposite may be true, as NOAA data offers some evidence of a decline.

Simply Yet another climate denial article propped up by the filthy fossil fuel industry. Patrick Michaels and Ryan a mere meteoroligist is simply a sockpuppet for the fossil fuel industry.

A review of claims made by the Cato Institute's Patrick Michaels over the last quarter century shows that he has repeatedly been proven wrong over time. Michaels is one of a few contrarian climate scientists who is often featured in the media without disclosure of his funding from the fossil fuel industry.

Patrick Michaels' Losing Bets
On Temperature Trends
Michaels "Bet" In 1999 There Would Be A "Statistically Significant Cooling Trend" From 1998 To 2008. In a Cato post that was later published as a Washington Times op-ed, according to Nexis, Patrick J. Michaels wrote that he would place a "bet" that "the 10 years ending on December 31, 2007, will show a statistically significant global cooling trend in temperatures measured by satellite":

I'm willing to wager two things. First, I'll bet that anyone who said global warming is an overblown bunch of hooey had a terrible time at this year's holiday cocktail parties. Second, I'll take even money that the 10 years ending on December 31, 2007, will show a statistically significant global cooling trend in temperatures measured by satellite.

Last year was so warm that it induces a statistically significant warming trend in the satellite data. Thus the second bet: Starting with 1998, there will almost certainly be a statistically significant cooling trend in the decade ending in 2007. [Cato, 1/18/99]

Satellite Records For That Decade Showed No Statistically Significant Trend. From 1998 to 2008, the University of Alabama in Huntsville satellite record shows a warming trend that is not statistically significant at the 95 percent level (a warming of 0.074°C per decade plus or minus 0.439°C). The Remote Sensing Systems satellite record shows a cooling trend that is not statistically significant at the 95 percent level (a change in temperature of -0.053°C per decade plus or minus 0.425 °C). The three surface temperature records showed a "warming trend" for that time period according to a Skeptical Science report on a 2008 paper by the Australian Bureau of Meteorology

Michaels' New Bet: "We Are Going To Go Nearly A Quarter Of A Century Without Warming." In a Washington Times op-ed in January 2013, Michaels stated "it's a pretty good bet that we are going to go nearly a quarter of a century without warming." [The Washington Times, 1/17/13]

On Ice Ages
Michaels Makes An "Easy Prediction" That By 2000 The "Vogue Environmental Calamity Will Be An Ice Age." Michaels wrote in a 1992 Washington Times op-ed:

About 15 years ago it was all the rage in the climate business to proclaim the coming ice age.

Here's an easy prediction: By the year 2000, plus or minus a few, the vogue environmental calamity will be an ice age. And this nouvelle apocalypse, revised version, will predict that global warming will cause sea level to fall, exposing Bangladesh to wrenching cultural changes, and therefore we should give more money to the Third World. [The Washington Times, 2/11/92, via Nexis]

Michaels' Failed Prediction Based On Misrepresentation Of Scientific History. There has been a persistent increase in temperatures and continuing warnings about the impacts of climate change from scientists and advocates, contrary to Michaels' prediction.

Blame the volcanoes. They produce 200 000 000 000 000 kg's of Carbon Dioxide annually.

Mmmmm, yes the irony is that all the Co2 we are pumping into the atmosphere came from there in the first place.
He he - just bringing back the equilibrium of the hot, humid swampy world of 200 million years ago in which huge dinosours thrived...

OK, I don't even pretend to be an environmental scientist, but let's at least try to do the conversions right. The USGS says that volcanoes of all kinds, including underwater volcanoes, produce about 200 million tons of CO2 annually. That is 200,000,000 tons. To convert to kg, you need to multiply by 1000, which adds another three zeros:
200,000,000,000 kg
This is three orders of magnitude less than the number quoted above. Also, the number is meaningless if you don't compare it to other sources, which based on a few articles that I read seem to show the amount output by volcanoes may be less than 1% of what humans generate annually. On the other hand, humans generate only a fraction of the total amount of CO2 produced each year, and that is the point where people start to dispute whether this is significant enough to influence the earth's climate. Nevertheless, you can't blame volcanoes, because their CO2 output is much less than that of human activity, which in turn accounts for much less than other natural sources such as the natural ocean-atmospheric exchange, animal respiration, and decomposition of bio-mass. Volcanoes make up such a small part of the natural CO2 generation (less than 0.05%) that it really is irrelevant in the bigger discussion.

Calm down? I don't think you have seen me mad yet :twisted:

However, in this case it changed the result completely: In one case volcanoes would be one of the biggest contributors to CO2 among the factors mentioned, in the other it is the smallest contributor. I'm an engineer - forgive me for being pedantic when an incorrect number completely changes the implications. There is enough misinformation already floating around when it comes to so-called global warming.
