President Donald Trump and his cabinet often avoid talking about the science of climate change, but when pressed what they have said clashes with established mainstream science, data and peer-reviewed studies and reports.
Even the federal government’s own reports — including a draft science study for the National Climate Assessment obtained this week by The Associated Press and other media — paint an entirely different reality than what’s coming from the Trump Administration.
COOLING and HOAX
President Trump has not talked directly about the science since taking office, but on the Hugh Hewitt radio show in 2015 he said: “I’m not a believer in man-made global warming. It could be warming, and it’s going to start to cool at some point. And you know, in the early, in the 1920s, people talked about global cooling.” And in a now famous social media post, Trump tweeted in 2012: “The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive.”
The usual talking point among non-scientists is that in the 1970s — not 1920s — experts thought the world was cooling. University of Georgia meteorology professor Marshall Shepherd calls this a “zombie myth” long disproven but somehow still sticking around. Scientists looked at peer-reviewed literature between 1965 and 1979 and found only seven papers talking about global cooling, 20 neutral and 44 implying global warming, according to a 2008 analysis in the Bulletin of the American Meteorological Society.
On global warming being a hoax invented by the Chinese, the previous National Climate Assessment, NASA , EPA, the National Academy of Sciences and many other scientific organizations say otherwise. The American Institute of Physics in a historical timeline says the first calculation of global warming dates back to 1896 and a Swiss scientist and even earlier, in 1859, an Irish physicist noticed certain gases trap heat.
ROLE OF HUMANS, CARBON DIOXIDE
Key members of Trump’s Cabinet have more recently questioned whether carbon dioxide and other greenhouse gases created by human activities are the primary cause for global warming.
Energy Secretary Rick Perry testifying before the Senate Energy Committee in June said: “I did not think that CO2 was the primary knob that changes it. I don’t. I think that there are some other naturally occurring events, the warming and the cooling of our ocean waters and some, you know, other activities that occur. I also…
