First Hiroshima, Now Global Warming Denial

The Faithful Heretic: A Wisconsin Icon Pursues Tough Questions (Dave Hoopman, Wisconsin Energy Cooperative News, May 2007)

Reid A. Bryson holds the 30th PhD in Meteorology granted in the history of American education. Emeritus Professor and founding chairman of the University of Wisconsin Department of Meteorology—now the Department of Oceanic and Atmospheric Sciences—in the 1970s he became the first director of what’s now the UW’s Gaylord Nelson Institute of Environmental Studies. He’s a member of the United Nations Global 500 Roll of Honor—created, the U.N. says, to recognize “outstanding achievements in the protection and improvement of the environment.” He has authored five books and more than 230 other publications and was identified by the British Institute of Geographers as the most frequently cited climatologist in the world.

Long ago in the Army Air Corps, Bryson and a colleague prepared the aviation weather forecast that predicted discovery of the jet stream by a group of B-29s flying to and from Tokyo. Their warning to expect westerly winds at 168 knots earned Bryson and his friend a chewing out from a general—and the general’s apology the next day when he learned they were right. Bryson flew into a couple of typhoons in 1944, three years before the Weather Service officially did such things, and he prepared the forecast for the homeward flight of the Enola Gay. Back in Wisconsin, he built a program at the UW that’s trained some of the nation’s leading climatologists.

How Little We Know

Bryson is a believer in climate change, in that he’s as quick as anyone to acknowledge that Earth’s climate has done nothing but change throughout the planet’s existence. In fact, he took that knowledge a big step further, earlier than probably anyone else. Almost 40 years ago, Bryson stood before the American Association for the Advancement of Science and presented a paper saying human activity could alter climate.

“I was laughed off the platform for saying that,” he told Wisconsin Energy Cooperative News.

In the 1960s, Bryson’s idea was widely considered a radical proposition. But nowadays things have turned almost in the opposite direction: Hardly a day passes without some authority figure claiming that whatever the climate happens to be doing, human activity must be part of the explanation. And once again, Bryson is challenging the conventional wisdom.

“Climate’s always been changing and it’s been changing rapidly at various times, and so something was making it change in the past,” he told us in an interview this past winter. “Before there were enough people to make any difference at all, two million years ago, nobody was changing the climate, yet the climate was changing, okay?”...

Bryson mentions the retreat of Alpine glaciers, common grist for current headlines. “What do they find when the ice sheets retreat, in the Alps?”

We recall the two-year-old report saying a mature forest and agricultural water-management structures had been discovered emerging from the ice, seeing sunlight for the first time in thousands of years. Bryson interrupts excitedly.

“A silver mine! The guys had stacked up their tools because they were going to be back the next spring to mine more silver, only the snow never went,” he says. “There used to be less ice than now. It’s just getting back to normal.”
