Muller concludes that humans are behind climate change.
Physicist Richard A. Muller was in the news last year after his Koch-funded study of global climate change concluded that it’s real, surely to the Koch brothers’ dismay. Now he’s penned an on-ed for the New York Times in which he says that his ongoing research has led him to the same conclusion as 99.9% of other experts in the field—that "essentially all of this increase results from the human emission of greenhouse gases." Muller’s research shows that the UN and the IPCC actually understate the problem. He researched the climate change causes claimed by non-scientist skeptics (urban heating biases, cherry-picking data, faking data, solar activity, and global population), and found that none of them explained climate change. What did explain it perfectly was atmospheric carbon dioxide. →
