"On Thursday, Sen. Bernie Sanders (I-Vt.) offered a simple amendment to the controversial bill that would authorize construction of the Keystone XL oil pipeline. Sanders' measure, which he proposed to the Senate Energy and Natural Resources Committee, would have declared it the "sense of Congress" that climate change is real; that it is caused by humans; that it has already caused significant problems; and that the United States needs to shift its economy away from fossil fuels.

Sanders' amendment went nowhere. But Sen. Lisa Murkowski (R-Alaska), the chair of the committee, used the opportunity to take a shot at climate science. "I do believe that our climate is changing," she said. "I don't agree that all the changes are necessarily due solely to human activity." Murkowski didn't elaborate on her current thinking about the causes of global warming, but in the past she's advanced a bizarre theory involving a volcano in Iceland.

Sanders will get another chance next week, when the full Senate debates the Keystone bill—but he's likely to run into stiff resistance from GOP climate deniers. As Climate Progress revealed Thursday, more than half of the Republican members of the new Congress "deny or question" the overwhelming scientific consensus that humans are causing climate change. If you just look at the Senate, the numbers are even more disturbing. Thirty-nine GOP Senators reject the scie"
