Meet NASA’s New ‘James Hansen’ – Gavin Schmidt – the man who hates debate & loses when he does debate – He has been criticized by prominent scientists for ‘erroneously communicating the reality of the how climate system is actually behaving’

Climate Depot Round Up of NASA”s New Lead Global Warming Scientist

NASA’s new lead global warming scientist, Gavin Schmidt, has history of belittling skeptical scientists, suppressing debate, condoning making climate data “impenetrable” and many of his scientific claims and his website, have been harshly criticized by scientists from around the world.

Schmidt replaces NASA’s James Hansen as Director of its Goddard Institute for Space Studies (GISS). Hansen retired in early 2013. See: NASA’s Lead Global Warming Scientist: Humans responsible for ’80 to 120% of the warming’ – Joe Romm gushes: ‘Meet Dr. Gavin Schmidt, NASA’s Replacement For James Hansen’ – Schmidt ‘was GISS deputy director, has a doctorate in applied mathematics, is ‘an expert in climate modeling.’

Hansen made a career out of smearing skeptics and getting arrested to draw attention to his opposition to the Keystone Pipeline. (For more on Hansen, see here, here, and here.:

Climate Depot has been following Gavin Schmidt’s career for years and presents the below round up of his climate change foibles.

Gavin Schmidt’s history: 

NASA’s Gavin Schmidt promotes hiding data!? I would simply put the whole CRU database (in an as-impenetrable-as-possible form’ – Warmist AGU gave a $25,000 award to Gavin Schmidt being the ‘best climate communicator in the world’

Physicist Dr. Motl rips Schmidt: ‘So if you want to be the best climate science communicator in the world, you have to release the data in an as-impenetrable-as-possible form. ;-)’

Prof. Pielke Jr. ‘I think we can get past the lie — and it was a lie — that these activist scientists, in the words of’s Gavin Schmidt, are not taking a political stand’

Israeli Astrophysicist Nir Shaviv has also been critical. “The aim of [Schmidt’s] is not to engage a sincere scientific debate. Their aim is to post a reply full of a straw man so their supporters can claim that your point ‘has been refuted by real scientists at,’” Shaviv’s website reported. Shaviv, who calls the website “,” noted that the “writers (at try again and again to concoct what appears to be deep critiques against skeptic arguments, but end up doing a very shallow job. All in the name of saving the world. How gallant of them.”

Via Daily Caller: In 2013, Fox Business host John Stossel asked about a dozen climate scientists to debate skeptic Dr. Roy Spencer, a former NASA scientist who now teaches at the University of Alabama. — Stossel also asked the environmental group the Union of Concerned Scientists if they would debate Spencer on TV. Stossel said UCS replied that debating Spencer “would be doing the public a disservice because it would give [his] extreme ideas credibility.” NASA Goddard Institute for Space Studies climate scientist Gavin Schmidt did go on that episode but only after Spencer was no longer on the set.

Climate Depot Exclusive: Real Climate Exposed! A Comprehensive Report on the ‘Real’

The global warming promoting website, is under fire yet again from a prominent scientist for presenting incorrect climate information. Climatologist Dr. Roger Pielke Sr. publicly rebuked the website in a June 30, 2009 article for “erroneously communicating the reality of the how the climate system is actually behaving.” Pielke, the former Colorado State Climatologist and currently a senior scientist at the University of Colorado in Boulder, countered Real Climate’s claim that warming was “progressing faster than expected” with the latest data on sea level rise, ocean heat content and Arctic ice.

In his article titled “Real Climate’s Misinformation”, Pielke also chastised readers of Real Climate for blindly accepting the incorrect climate claims promoted on the site.

“Media and policymakers who blindly accept these claims are either naive or are deliberately slanting the science to promote their particular advocacy position,” Pielke Sr. wrote., a website which much of the mainstream media has relied on for climate science developments, has come under increasing criticism and scrutiny from scientists. Real Climate’s lead blogger and NASA scientist Gavin Schmidt was harshly criticized for some of his scientific claims in January 2009. Atmospheric scientist Dr. Hendrik Tennekes, a prominent scientist from the Netherlands, wrote a scathing denunciation of Schmidt in which he said he was “appalled” by Schmidt’s “lack of knowledge” and added, “Back to graduate school, Gavin!” [Note: In an interview in the Dutch paper De Telegraaf, Tennekes says he was ousted from his position at the Royal Dutch Meteorological Institute due to his skepticism over climate change. After publishing a column critical of climate model accuracy, Tennekes says he was told “within two years, you’ll be out on the street”.]

The latest scientific woes by were rebutted point by point by Pielke on June 20, 2009.

Real Climate claimed:

“Our regular readers will hardly be surprised by the key findings from physical climate science, most of which we have already discussed here. Some aspects of climate change are progressing faster than was expected a few years ago – such as rising sea levels, the increase of heat stored in the ocean and the shrinking Arctic sea ice.”

Pielke responded:

“First, what is ‘physical climate science’? How is this different from ‘climate science’. In the past, this terminology has been used when authors ignore the biological components of the climate system,” Pielke wrote.

Atmospheric scientist Dr. Hendrik Tennekes, a prominent scientist from the Netherlands, wrote a scathing denunciation of Schmidt in which he said he was “appalled” by Schmidt’s “lack of knowledge” and added, “Back to graduate school, Gavin!”

“Roger Pielke, Sr. has graciously invited me to add my perspective to his discussion with Gavin Schmidt at Real Climate. If this were not such a serious matter, I would have been amused by Gavin’s lack of knowledge of the differences between weather models and climate models. As it stands, I am appalled. Back to graduate school, Gavin!” Tennekes wrote on January 29, 2009. Tennekes, is an scientific pioneer in the development of numerical weather prediction and former director of research at The Netherlands’ Royal National Meteorological Institute, and an internationally recognized expert in atmospheric boundary layer processes. Tennekes is also featured in U.S. Senate Minority Report Update: More Than 700 International Scientists Dissent Over Man-Made Global Warming Claims “Gavin Schmidt is not the only meteorologist with an inadequate grasp of the role of the oceans in the climate system. In my weblog of June 24, 2008, I addressed the limited perception that at least one other climate modeler appears to have,” Tennekes wrote. “From my perspective it is not a little bit alarming that the current generation of climate models cannot simulate such fundamental phenomena as the Pacific Decadal Oscillation. I will not trust any climate model until and unless it can accurately represent the PDO and other slow features of the world ocean circulation. Even then, I would remain skeptical about the potential predictive skill of such a model many tens of years into the future,” Tennekes added.

Atmospheric Physicist James A. Peden, formerly of the Space Research and Coordination Center in Pittsburgh, also critiqued on June 24, 2008. Peden wrote, “’Real Climate’ is a staged and contracted production, which wasn’t created by ‘scientists,’ it was actually created by Environmental Media Services, a company which specializes in spreading environmental junk science on behalf of numerous clients who stand to financially benefit from scare tactics through environmental fear mongering.”

Meteorologist Joe D’Aleo also launched a sharply worded critique of in January 2009 titled “Response to Gavin Schmidt – Global Data Base Issues Are Real.” “To Gavin [Schmidt] and the other alarmists, it appears, a piece that is fair and balanced can make no mention of any other opinion except that carbon dioxide is causing global warming and action is needed now and will deliver gain and no pain, something the one sided media coverage has gotten them used to over the years,” D’Aleo wrote on January 13, 2009. D’Aleo served as the first Director of Meteorology at The Weather Channel and served as chairman of the American Meteorological Society’s Committee on Weather Analysis and Forecasting.

Israeli Astrophysicist Nir Shaviv has also been critical. “The aim of is not to engage a sincere scientific debate. Their aim is to post a reply full of a straw man so their supporters can claim that your point ‘has been refuted by real scientists at,’” Shaviv’s website reported. Shaviv, who calls the website “,” noted that the “writers (at try again and again to concoct what appears to be deep critiques against skeptic arguments, but end up doing a very shallow job. All in the name of saving the world. How gallant of them.”

Excerpt: The analysis concluded, “Looks like [study author] Steig ‘got rid of’ Antarctic cooling the same way [Michael] Mann got rid of medieval warming. Why not just look at the station data instead of ‘adjusting’ it (graph above)? It shows a 50-year cooling trend,” the analysis concluded.

Pielke Jr.: ‘Gavin Schmidt admits to stealing a scientific idea from his arch-nemesis, Steve McIntyre’ – February 4, 2009 – Excerpt: This is not a hypothetical example, but a caricature of real goings on with our friends over at Real Climate … Due to an inadvertent release of information, NASA’s Gavin Schmidt (a “real scientist” of the Real Climate blog) admits to stealing a scientific idea from his arch-nemesis, Steve McIntyre (not a “real scientist” of the Climate Audit blog) and then representing it as his own idea, and getting credit for it. In his explanation why this is OK, Gavin explains that he did some work on his own after getting the idea from Steve’s blog, and so it was OK to take full credit for the idea. […] Gavin’s outing is remarkable because it shows him not only stealing an idea, but stealing from someone who he and his colleagues routinely criticize as being wrong, corrupt, and a fraud. Does anyone wonder why skepticism flourishes? When evaluations of expertise hinge on trust, stealing someone’s ideas and taking credit for them does not help.

Its messages include: weather will kill you; our moment on Earth is unique; and climate did not used to change. Had you wanted to fulfill the responsibilities of an objective and hard-hitting journalist, you might have asked Schmidt about the image of Lake Powell on his book’s cover. […] Were you aware, may I ask, of the controversial nature of the damming of the Colorado River that led to Lake Powell? Environmentalists were and are appalled by this particular dam. It has changed an important piece of the American natural landscape. […] Group-think has affected many societies negatively, and it has not disappeared during our own time. The fact that neither Mr. Schmidt’s editor, nor his publisher, nor you, nor the photographer, nor Mr. Schmidt himself would stop to reflect on the oddity of this cover is enough to give one pause.

Excerpt: After reading this latest statistical analysis, I think it is fair to conclude that the paper’s premise has been falsified.

It is a lot like “spin art” you see at the county fair.

Scientists, Data Challenge Real Climate Touted Antarctic ‘Warming’ Study – ‘It is hard to make data where none exist’ – January 21, 2009

The Truth about – July 6, 2009 – Excerpt: Essentially the site exists to promote global warming alarm-ism and attack anyone who does not agree with their declaration of doomsday (proven of course by their own computer climate models) and the need for government intervention against the life supporting, atmospheric trace gas, carbon dioxide. Standard operating procedure is to post “rebuttals” to everything they disagree with and then declare victory, making sure to censor comments challenging their position. It doesn’t matter if they actual rebutted any of the science or facts just so long as they provide the existence of a criticism. This gives their fanboys “ammunition” to further promote alarmist propaganda across the Internet (and of course declare victory). Their resident propagandist William Connolley’s job is to edit dissent and smear skeptical scientists on Wikipedia. In the world of global warming alarmist “science” pretending you win is apparently all that matters because in real debates they lose. The truth is that is an environmentalist shill site directly connected to an eco-activist group, Environmental Media Services and Al Gore but they don’t want you to know that.

New spin on the ‘pause’ NASA’s ‘Gavin Schmidt is concerned that the temperature hasn’t decreased over this period’

Climate Depot Analysis: ‘There have been at least seven separate explanations for the standstill in global warming’ – 1) Low Solar Activity; 2) Oceans Ate Warming; 3) Chinese Coal Use; 4) Montreal Protocol; 5) Readjusted past temps to claim ‘pause’ never existed 6) Volcanoes 7) Decline in Water Vapor

If so, such a decline would obviously discredit the rest of the reconstruction.

Flashback NASA climate modeler Gavin Schmidt — admitted last week that the “chaotic component of climate system…is not predictable beyond two weeks, even theoretically.”

Schmidt made his admission during a June 29, 2009 interview about the shortcomings of climate models. Schmidt noted that some climate models “suggest very strongly” that the American Southwest will dry in a warming world. But Schmidt also noted that “other models suggest the exact opposite.”

“With these two models, you have two estimates — one says it’s going to get wetter and one says it’s going to get drier. What do you do? Is there anything that you can say at all? That is a really difficult question,” Schmidt conceded.

“The problem with climate prediction and projections going out to 2030 and 2050 is that we don’t anticipate that they can be tested in the way you can test a weather forecast. It takes about 20 years to evaluate because there is so much unforced variability in the system which we can’t predict — the chaotic component of the climate system — which is not predictable beyond two weeks, even theoretically. That is something that we can’t really get a handle on,” Schmidt lamented. [Note: Schmidt has been under fire for his website’s recent scientific woes at See: Climate Depot Report: Real Climate Exposed! A Comprehensive Report on the ‘Real’ – June 30, 2009 ]

Climate models made by unlicensed ‘software engineers’

The credibility of these computer model predictions — used by governments to determine global warming policy based on future climate risks — have been under increasingly intense scrutiny for years.

In June 2007, Dr. Jim Renwick, a top UN IPCC scientist, admitted that climate models do not account for half the variability in nature and thus are not reliable. “Half of the variability in the climate system is not predictable, so we don’t expect to do terrifically well,” Renwick conceded. (LINK)

Another high-profile UN IPCC lead author, Dr. Kevin Trenberth, echoed Renwick’s sentiments in 2007 about climate models by referring to them as “story lines.”

“In fact there are no predictions by IPCC at all. And there never have been. The IPCC instead proffers ‘what if’ projections of future climate that correspond to certain emissions scenarios,” Trenberth wrote in journal Nature’s blog on June 4, 2007.

Trenberth also admitted that the climate models have major shortcomings because “they do not consider many things like the recovery of the ozone layer, for instance, or observed trends in forcing agents. There is no estimate, even probabilistically, as to the likelihood of any emissions scenario and no best guess.” (LINK)

IPCC reviewer and climate researcher Dr Vincent Gray, of New Zealand, an expert reviewer on every single draft of the IPCC reports going back to 1990, author of more than 100 scientific publications and author of The Greenhouse Delusion: A Critique of “Climate Change 2001,” declared “The claims of the IPCC are dangerous unscientific nonsense” in an April 10, 2007 article.(LINK) & (LINK)

“All [UN IPCC does] is make ‘projections’ and ‘estimates’. No climate model has ever been properly tested, which is what ‘validation’ means, and their ‘projections’ are nothing more than the opinions of ‘experts’ with a conflict of interest, because they are paid to produce the models. There is no actual scientific evidence for all these ‘projections’ and ‘estimates,’” Gray noted.

In addition, atmospheric scientist Dr. Hendrik Tennekes, a scientific pioneer in the development of numerical weather prediction and former director of research at The Netherlands’ Royal National Meteorological Institute, recently compared scientists who promote computer models predicting future climate doom to unlicensed “software engineers.”

“I am of the opinion that most scientists engaged in the design, development, and tuning of climate models are in fact software engineers. They are unlicensed, hence unqualified to sell their products to society,” Tennekes wrote on February 28, 2007. (LINK)

Climate Models Likened to Sony ‘PlayStation’ Video Games & ‘Tinker Toys’

On a New Zealand radio interview in 2007, the late Atmospheric Scientist Augie Auer ridiculed climate model predictions: “Most of these climate predictions or models, they are about a half a step ahead of PlayStation 3 . They’re really not justified in what they are saying. Many of the assumptions going into [the models] are simply not right.” (LINK)

Atmospheric physicist James Peden ridiculed climate models in October 2008, calling them “computerised tinker toys with which one can construct any outcome he chooses.” (LINK)

In addition, top forecasting experts now say the models violate the basic principles of forecasting.

1) Ivy League forecasting pioneer Dr. Scott Armstrong “Of 89 principles [of forecasting], the UN IPCC violated 72.” – January 28, 2009

2) Forecast Pioneers: Climate modelers violated 49 principles of forecasting – June 16, 2009

In addition, Prominent Physicist Freeman Dyson has referred to climate models as “rubbish.”

Dyson is a Professor Emeritus of Physics at the Institute for Advanced Study at Princeton University, a fellow of the American Physical Society, a member of the US National Academy of Sciences, and a fellow of the Royal Society of London.

“The fuss about global warming is grossly exaggerated,” writes Dyson in his 2007 book “Many Colored Glass: Reflections on the Place of Life in the Universe.” (See: Dyson: Climate models are rubbish – August 14, 2007)

Dyson is blunt in his criticism of climate models, mocking “the holy brotherhood of climate model experts and the crowd of deluded citizens who believe the numbers predicted by the computer models.”

“I have studied the climate models and I know what they can do. The models solve the equations of fluid dynamics, and they do a very good job of describing the fluid motions of the atmosphere and the oceans. They do a very poor job of describing the clouds, the dust, the chemistry, and the biology of fields and farms and forests,” Dyson wrote.
