Following her election victory on Tuesday night, veteran Republican U.S. Senator Lisa Murkowski of Alaska assured her constituents that she takes climate change very seriously, and talked about thinning ice and the changing migratory patterns of birds that cross through the state.

However Murkowski, who took the helm of the Committee on Energy and Natural Resources as of Tuesday’s Republican takeover in the Senate, thinks about climate change rather unconventionally. Rather than pointing to the typical culprits of climate change (i.e., man-made emissions from planes, trains, automobiles and the like), she claims that a volcano in Iceland is the cause of warming–not just in the northern regions, but globally as well.

“The emissions that are being put in the air by that volcano are a thousand years’ worth of emissions that would come from all of the vehicles, all of the manufacturing in Europe,” she told NPR on Tuesday.

This belief is strongly contradicted by the latest U.N. Report on climate change, a dire 100-page warning that human driven emissions may need to drop to zero by the end of the century in order to stabilize the climate system.

Murkowski’s claim was also contradicted by Princeton climate expert Michael Oppenheimer. “It’s simply untrue,” Oppenheimer said. “I don’t know where she gets that number from.” He went on to explain that the opposite of her theory is true, and that human carbon dioxide emissions are many more magnitudes higher than natural sources of emissions, such as volcanoes.
