Crackpot is not a term anyone could reasonably use to describe Petr Chylek. He's an adjunct professor in the department of physics and atmospheric science at Dalhousie University, and a past senior chair in climate research at the Natural Sciences and Engineering Research Council of Canada. A specialist on the subject of the Greenland ice sheet, he certainly does not believe global warming is caused by CO2 generated by human activity, though he is willing to admit that, in the scientific community, scientists who oppose the hysteria are still in the minority. "But if you look at the scientists who dissent, really, these are the leaders in their fields," he says confidently.

Chylek is particularly upset with the way global warming supporters have been misrepresenting data to support their cause. For instance, in An Inconvenient Truth, Gore claims that between 1992 and 2005 the melt area of Greenland increased drastically. This is technically correct, Chylek says. But Gore fails to mention that a volcanic eruption from Mount Pinatubo in 1992 caused temperatures to become depressed all over the earth; the years following were naturally warmer. "He's comparing 1992 with 2005," says Chylek. "If he would compare 1991 with 2005, he would find that the Greenland melt area in 1991 was larger than 2005. So he just picks the special year 1992, when the melt area of Greenland was very, very small due to the Mount Pinatubo volcanic eruption. And this lets him show and pretend that this difference between 1992 and 2005 is due to global warming and that's completely untrue," Chylek says.
