One of the fright tricks used by AGW believers to gin up fear of global warming is the claim that rising temperatures will melt the arctic permafrost, thus releasing even more carbon into the atmosphere. But that prediction appears to be a stretch, at best.
According to a recent field study of ice wedges conducted by researchers at the University of Alberta, the permafrost has survived numerous warming spells in past millenia that were far worse than what we are supposed to be facing.
“The general view is that everything would have melted out back then,” Dr. [Duane] Froese said. The new finding suggests that wasn’t the case, and that models of future melting need to be rethought.
Of course, Dr. Froese is then quick to throw a sop to the AGW crowd, acknowledging that global warming is still a serious threat, yada, yada. But it’s another case of hard science casting doubt on the prevailing paradigm.
