Kudos to John L. Daly, who has written a very interesting study of ice at the North Pole. Global Warmists are once again observing cyclical changes and declaring them "proof" of the dire effects of global warming.Among the interesting pictures posted to this site is this one from 1987, when we were supposed to be worried about global cooling:USS Hawkbill at the North Pole, Spring 1999. (US Navy Photo) Daly explores the various factors influencing ice at the North Pole. It is accessible to laymen like me. His conclusions:...both the extent and thickness of Arctic sea ice is certainly subject to variation. But it would be a mistake to assume that a brief period during which the Arctic is in a thinning cycle is anything more than that - a cycle. We know from past history that it has been subject to earlier retreats....Part of the problem lay in the fact that useful data on ice extent and thickness only dates from the 1950s, yet our temperature record from Jan Mayen Island...(Read Full Post)
