FACT: NASA scientist: Emails show “no manipulation”

NASA's Gavin Schmidt: “There's nothing hidden, no manipulation” Wired's Threat Level blog reported on November 20 that Gavin Schmidt, a climate scientist at NASA's Goddard Institute for Space Studies, said: “There's nothing in the e-mails that shows that global warming is a hoax. ... There's no funding by nefarious groups. There's no politics in any of these things; nobody from the [United Nations] telling people what to do. There's nothing hidden, no manipulation. It's just scientists talking about science, and they're talking relatively openly as people in private e-mails generally are freer with their thoughts than they would be in a public forum. The few quotes that are being pulled out [are out] of context. People are using language used in science and interpreting it in a completely different way.” Schmidt is a contributor to the RealClimate blog, which has stated that some of the reportedly stolen CRU emails “involve people” at RealClimate. Moreover, RealClimate.org's staff has refuted the distortion of an email that has been repeatedly cited by critics to claim that the emails undermine global warming science, noting that the terms “trick” and “hide the decline” that appeared in a 1999 email represent an “example” of “instances of cherry-picked and poorly-worded 'gotcha' phrases [being] pulled out of context.” RealClimate.org explained that "[s]cientists often use the term 'trick' to refer to a 'a good way to deal with a problem', rather than something that is 'secret', and so there is nothing problematic in this at all," and noted that “hiding the decline” refers to a method that is “completely appropriate.”

FACT: Emails do not undermine global climate change

UCS: “The e-mails provide no information that would affect the scientific understanding of climate change.” The Union of Concerned Scientists (UCS) has stated that "[t]he e-mails provide no information that would affect the scientific understanding of climate change, as many contrarians are falsely claiming. For years, thousands of scientists working at climate research centers around the world have carefully and rigorously reached a consensus on the extent of climate change, the urgency of the problem, and the role human activity plays in causing it." UCS further stated: “The findings of the USGCRP, IPCC and other scientific bodies are based on the work of thousands of scientists from hundreds of research institutions. The University of East Anglia's Climate Research Unit (CRU) is just one among many such research institutions. Even without data from CRU, there is still an overwhelming body of evidence that human activity triggering dangerous levels of global warming.”

Peter Kelemen: "[A]lleged problems with a few scientists' behavior do not change the consensus understanding of human-induced, global climate change." Kelemen, a professor of geochemistry at Columbia University's Department of Earth and Environmental Sciences, wrote that “I think it is important for scientists to clearly state that if basic data were withheld, or if there was unprofessional tampering with the peer-review process, we do not condone these acts. It is equally essential to emphasize that alleged problems with a few scientists' behavior do not change the consensus understanding of human-induced, global climate change, which is a robust hypothesis based on well-established observations and inferences.” Kelemen further wrote: “Outspoken critics often portray climate science as a house of cards, built on a shaky edifice of limited data and broad suppositions. However, it's more realistic to think of the science as a deck of cards, spread out, face up. Some data and interpretations of those data are more certain than others, of course. But pulling out one or two interpretations, or the results of a few scientists, does not change the overall picture. Take away two or three cards, and there are still 49 or 50 cards facing you.”

Nature: “Nothing in the e-mails undermines the scientific case that global warming is real.” A December 2 editorial in the science journal Nature stated: “Nothing in the e-mails undermines the scientific case that global warming is real -- or that human activities are almost certainly the cause. That case is supported by multiple, robust lines of evidence, including several that are completely independent of the climate reconstructions debated in the e-mails.” Also from the editorial:

The stolen e-mails have prompted queries about whether Nature will investigate some of the researchers' own papers. One e-mail talked of displaying the data using a 'trick' -- slang for a clever (and legitimate) technique, but a word that denialists have used to accuse the researchers of fabricating their results. It is Nature's policy to investigate such matters if there are substantive reasons for concern, but nothing we have seen so far in the e-mails qualifies.

AMS: Impact on climate change science of emails “very limited.” Following the release of the stolen emails, the American Meteorological Society (AMS) reaffirmed its Statement on Climate Change, stating that it “is based on a robust body of research reported in the peer-reviewed literature.” AMS further stated: “For climate change research, the body of research in the literature is very large and the dependence on any one set of research results to the comprehensive understanding of the climate system is very, very small. Even if some of the charges of improper behavior in this particular case turn out to be true -- which is not yet clearly the case -- the impact on the science of climate change would be very limited.”
