Dems say climate change 'deniers' like ‘teabaggers,’ swiftboaters, people who don’t believe smoking causes cancer

“There is no magician trying to trick his audience,” Markey said. "Our world is getting hotter, faster."

That was a specific reference to one of the more controversial emails in the bunch. An email dated Nov. 12, 1999, from Prof. Phil Jones references a “trick” to “hide a decline.”

Markey said the word trick in this case meant a clever way to fix a perplexing problem, and didn’t indicate that the scientists were playing funny with the numbers. The decline relates to data from tree rings that did not correspond to actual temperatures in the region from 1960 to 1994. See a response from the Pew Center of Global Climate Change here.

Climate skeptics say the emails show climate scientists have manipulated data and sought to suppress divergent views.

“The e-mails reveal that leading climate 'experts' deliberately destroyed records, manipulated data to 'hide the decline' in global temperatures, and tried to silence their critics by preventing them from publishing in peer-reviewed journals,” Palin wrote.

“Before Sarah Palin writes a book, she should try reading a few,” Inslee said. He then listed several reports on climate change, including the National Academy of Science's report in 2007 that concluded with 90 percent assurance that according to Inslee found that  “in fact we are heading down a very dangerous road due to human-induced climate change."
