Koch-Funded Scientist: ‘Global Warming Is Pretty Much Beyond Dispute Now’ | A forthcoming report from the Intergovernmental Panel on Climate Change compiles scientists’ findings that global warming pollution is making weather more extreme and dangerous, at a huge cost. Last night, NBC’s Anne Thompson reported on the growing threat on NBC Nightly News. “This is the future,” scientist Gerry Meehl said, “and we’re already experiencing climate change,” comparing the effect of global warming to steroids. “This is really the first time the impact of climate change has manifested itself in a tangible way in the state of Texas,” state climatologist John Nielsen-Gammon said of its killer drought. “The existence of global warming is pretty much beyond dispute now,” physicist Richard Muller told Thompson. She noted that Muller’s climate study was funded by the “climate-change denier” Koch brothers.
