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:

This was not exactly a harbinger of global warming, as this picture of unbroken ice at the North Pole three years later attests:
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 as suggested by the opening quote from 1817. [snip]READ MORE
There is nothing in the data to suggest anything but natural cycles at work.
