For a short time during the 1970s, a number of climatologists theorized that the Earth was heading towards an ice-age. Leading this group was Reid Bryson, whose work was the primary inspiration for a number of CIA reports and the book The Weather Conspiracy. At one point, Mr. Bryson wrote that:
“There is very important climatic change going on right now, and it’s not
merely something of academic interest.” Bryson warned, “It is something that, if it continues, will affect the whole human occupation of the earth – like a billion people starving. The effects are already showing up in a rather drastic way.”
However, this theory was soon abandoned. Bryson recanted his earlier warnings and eventually retired (in 1986, by my calculations). Meanwhile, the above quote became fodder for a million GW Denier websites, evidence that scientists "can’t decide whether we face an ice age or warming".
And then, just last week, Reid Bryson pops up in the "Wisconsin Energy Cooperative News" , the magazine of the Wisconsin Energy Cooperative, an association of Wisconsin energy producers. In "The Faithful Heretic", he spends a several pages trash-talking the science behind anthropogenic Global Warming, employing most of the standard skeptical talking points.
And suddenly, the guy once ridiculed for being wrong about Global Cooling has become a prophet for GW Deniers everywhere! Oh how the worm turns!
(Actually, it is a little bit unfair to Bryson to say that he "retired" two decades ago. He has still continued to publish occasionally, and was calling James Hansen's concerns re. Global Warming a "snow job" back in the early 1990s. So he is not a recent "convert" to the ranks of GW skepticism, as some have contended.)
