Dyson made his skepticism clear: “My first heresy says that all the fuss about global warming is grossly exaggerated. Here I am opposing the holy brotherhood of climate model experts and the crowd of deluded citizens who believe the numbers predicted by the computer models.” He went on, saying that the climate models “do not begin to describe the real world that we live in. The real world is muddy and messy and full of things that we do not yet understand.”
The essential line in Dyson’s 2007 essay is this: “The humanist ethic accepts an increase of carbon dioxide in the atmosphere as a small price to pay, if world-wide industrial development can alleviate the miseries of the poorer half of humanity.”
Dyson on climate science: "In the end, everything is decided by who gets the money."
Dutch filmmaker Marijn Poels in 2018 documentary: "Freeman Dyson, a living legend in the fields of mathematics and physics. 93 years old. He was one of the first scientists in the 70s who started to investigate climate change."
Freeman Dyson: "I was there I think around 1970 to 1980. So this was a very active group of not just climate experts, we tried to measure everything and to see what the effects of carbon dioxide really are in the real world. Then there was another group of people, mostly in Colorado, who did computer calculations. Looking at the climate from a theoretical point of view. And then, of course, there became a political fight, which was these groups would get the money and so, in the end, everything is decided, of course, by who gets the money and, so the people in Colorado won."
Dyson on climate change scientists: "I don't say they're dishonest. I think they are inevitably influenced by the fact that they live by scaring the public, that if they did not scare the public they wouldn't get support from the government...In the end, everything is decided by who gets the money."
Nat Geo excerpt: Freeman Dyson's criticism of climate science grew out of his own involvement with the JASON group and developed amid the nuclear winter debate with Carl Sagan and others. In his own simple climate model, Dyson underplayed the effects of greenhouse gases. Atmospheric physicists savaged his model for going against a broad consensus. That stung Dyson, who insisted that "global warming is grossly exaggerated as a problem." His skepticism continued to bring scathing criticism during his final years, as evinced in a New York Times Magazine article headlined "The Civil Heretic."
Excerpt from Freeman Dyson's email to Climate Depot's Marc Morano on March 3, 2018: Dyson: "Congratulations for the success of the book and for the serious attention it is getting from people who matter. The experts will of course continue to put you down with a sneer. The people who matter are those who are not experts but can tell when they are being scammed. Keep up the good work! Yours sincerely, Freeman Dyson."
