Wigley says that sulfate aerosols will be legislated out of existence faster than previously thought. He champions the theory that sulfates reflect away the sun's radiation, conveniently explaining why the planet has warmed so little despite the claims of warming doomsayers and their computers.
Without sulfate aerosols, computer models indicate our hemisphere should have already warmed about 2.3 degrees Celsius as a result of the greenhouse effect. The observed warming this century is a scant 0.65 degrees. If the sulfate hypothesis fails, the argument devolves into what the "skeptics" have said for decades: the earth simply isn't going to warm all that much.
n October 1994, at a global warming meeting called by Rep. John Dingell (D-Mich.), Wigley was confronted with the reality that satellites had found no warming. He merely waved his hands and said, "Oh come now, that's just the satellite data." Oh come now, Tom, it's just the only global measure of temperature that exist.
