A prominent global warming skeptic funded by the Charles G. Koch Charitable Foundation has publicly reversed himself and now agrees with the vast majority of mainstream climate scientists who conclude Earth's temperature really is quickly rising. Richard Muller, a physicist and well known climate skeptic, did his own research and calculated that the land is now 1.6 degrees warmer than it was in the 1950s -- figures that match those produced by the National Oceanic and Atmospheric Administration (NOAA) and National Aeronautic and Space Administration (NASA). Billionaire Charles G. Koch, founder of the Charles G. Koch Foundation, is a well-known funder of global warming skeptics. Together with his billionaire brother, David, the Kochs own the country's largest, privately-held energy company, Koch Industries, which produces significant greenhouse gases and fights efforts to reduce carbon emissions in the U.S. Koch Industries has long worked to undermine environmental protections and protect corporate polluters. Koch Industries is also a long-time member and funder of the American Legislative Exchange Council (ALEC), a nonprofit group that helps corporate representatives draft and advance "model" bills that benefit their bottom line, and get the bills into the hands of legislators who introduce them in state houses as though they were their own ideas. ALEC also provides corporate-drafted "model" resolutions legislators can introduce that are aimed at thwarting efforts to address climate change.
