FactCheck.org published an article regarding the controversy over e-mails between scientists at the Climate Research Unit of the U.K.’s University of East Anglia which were stolen and made public by an as-yet-unnamed hacker. The emails don’t change the consensus: our actions have contributed directly to global warming.
From the article:
The e-mails (which have been made available by an unidentified individual here) do show a few scientists talking frankly among themselves — sometimes being rude, dismissive, insular, or even behaving like jerks. Whether they show anything beyond that is still in doubt. There are two investigations underway, by the U.K.’s Met Office and East Anglia University, and the head of CRU, Phil Jones, has "stepped aside" until they are completed. However, many of the e-mails that are being held up as "smoking guns" have been misrepresented by global-warming skeptics eager to find evidence of a conspiracy. And even if they showed what the critics claim, there remains ample evidence that the earth is getting warmer. Even as the affair was unfolding, the World Meteorological Organization announced on Dec. 8 that the 2000-2009 decade would likely be the warmest on record, and that 2009 might be the fifth warmest year ever recorded. (The hottest year on record was 1998.) This conclusion is based not only on the CRU data that critics are now questioning, but also incorporates data from the U.S.
The e-mails are being exploited to confuse the public:
News converage of the e-mails and the various claims about what they supposedly show may have contributed to public confusion on the subject. A Dec. 3 Rasmussen survey found that only 25 percent of adults surveyed said that "most scientists agree on global warming" while 52 percent said that "there is significant disagreement within the scientific community" and 23 percent said they were not sure. The truth is that over the 13 years covered by the CRU e-mails, scientific consensus has only become stronger as the evidence for global warming from various sources has mounted. Reports from the National Academies and the U.S. Global Change Research Program that analyze large amounts of data from various sources also agree, as does the IPCC, that climate change is not in doubt. In advance of the 2009 U.N. climate change summit, the national academies of 13 nations issued a joint statement of their recommendations for combating climate change, in which they discussed the "human forcing" of global warming and said that the need for action was "indisputable."
The anti-science crowd needs to face the music. What people say in casual emails and conversations in the course of real research is not as neat and clean as the final result. Emails and personal correspondence aren’t the scientific record; peer-reviewed journal articles containing validated data and analysis are what counts in the end.
