Rep. Paul Ryan (R-WI), Mitt Romney’s vice-presidential pick, is a virulent denier of climate science, with a voting record to match.

A favorite of the Koch brothers, Ryan has accused scientists of engaging in conspiracy to “intentionally mislead the public on the issue of climate change.” He has implied that snow invalidates global warming.

Ryan has voted to prevent the Environmental Protection Agency from limiting greenhouse pollution, to eliminate White House climate advisers, to block the U.S. Department of Agriculture from preparing for climate disasters like the drought devastating his home state, and to eliminate the Department of Energy Advanced Research Projects Agency (ARPA-E):

Paul Ryan Promoted Unfounded Conspiracy Theories About Climate Scientists. In a December 2009 op-ed during international climate talks, Ryan made reference to the hacked University of East Anglia Climatic Research Unit emails. He accused climatologists of a “perversion of the scientific method, where data were manipulated to support a predetermined conclusion,” in order to “intentionally mislead the public on the issue of climate change.” Because of spurious claims of conspiracy like these, several governmental and academic inquiries were launched, all of which found the accusations to be without merit.

Paul Ryan Argued Snow Invalidates Global Warming Policy. In the same anti-science, anti-scientist December 2009 op-ed, Ryan argued, “Unilateral economic restraint in the name of fighting global warming has been a tough sell in our communities, where much of the state is buried under snow.” Ryan’s line is especially disingenuous because he hasn’t been trying to sell climate action, he’s been spreading disinformation.
