Freeman Dyson: speaking out on “global warming”

From Watts Up With That, March 26, 2009

Freeman Dyson

Freeman Dyson

This is a well written essay by the New York times on Freeman Dyson. Dyson is one of the world’s most eminent physicists. As many WUWT readers know he is a skeptic of AGW aka “global warming”, even going so far as to signing the Oregon Petition, seen below.

This part really spoke to me:

What may trouble Dyson most about climate change are the experts. Experts are, he thinks, too often crippled by the conventional wisdom they create, leading to the belief that “they know it all.” The men he most admires tend to be what he calls “amateurs,” inventive spirits of uncredentialed brilliance like Bernhard Schmidt, an eccentric one-armed alcoholic telescope-lens designer; Milton Humason, a janitor at Mount Wilson Observatory in California whose native scientific aptitude was such that he was promoted to staff astronomer; and especially Darwin, who, Dyson says, “was really an amateur and beat the professionals at their own game.”

You can read an essay about his views on climate change, posted here on WUWT  on 11/05/2007.

Excerpt: from the NYT article:

IT WAS FOUR YEARS AGO that Dyson began publicly stating his doubts about climate change. Speaking at the Frederick S. Pardee Center for the Study of the Longer-Range Future at Boston University, Dyson announced that “all the fuss about global warming is grossly exaggerated.” Since then he has only heated up his misgivings, declaring in a 2007 interview with Salon.com that “the fact that the climate is getting warmer doesn’t scare me at all” and writing in an essay for The New York Review of Books, the left-leaning publication that is to gravitas what the Beagle was to Darwin, that climate change has become an “obsession” — the primary article of faith for “a worldwide secular religion” known as environmentalism. Among those he considers true believers, Dyson has been particularly dismissive of Al Gore, whom Dyson calls climate change’s “chief propagandist,” and James Hansen, the head of the NASA Goddard Institute for Space Studies in New York and an adviser to Gore’s film, “An Inconvenient Truth.” Dyson accuses them of relying too heavily on computer-generated climate models that foresee a Grand Guignol of imminent world devastation as icecaps melt, oceans rise and storms and plagues sweep the earth, and he blames the pair’s “lousy science” for “distracting public attention” from “more serious and more immediate dangers to the planet.”

“The climate-studies people who work with models always tend to overestimate their models,” Dyson was saying. “They come to believe models are real and forget they are only models.”

Mankind is always pushing the panic button about something. Global warming by co2 is one. Virtually everything is dynamic, not static. Even the universe. Therefore it is not surprising that climate is not static. It varies warmer and cooler. i.e. increasing cloud cover reflects radiation away from the earth, and the earth cools. This is a NEGATIVE feedback. Negative feedback keeps systems stable. Your eyes tell you that you are drifting off the road, so you correct. Your eyes provide negative feedback. Co2 is probably the least plausible g.w. factor. Sun spot frequency occurs in 11 yr. cycles. Rainfall amounts follow that cycle. That ought to provide a clue. Understanding the feedback mechanisms affecting climate is a priority. With that we will truly understand the dynamics and stability of earth climate.
