I should note that, since reading your post, Therese, I have heard from several different sources concerning this large 'island' of ice breaking off Ellesmere Island. During the course of this, though, I've also found that very much the same thing happened 35 years ago, when the Earth was just emerging from a mild cooling trend. (Of course, this didn't stop numerous scientists during the '70s from warning the world about a coming ice age.)
An ice age can be precitipated by the results of a warming trend, and very quickly and cataclysmicly . . . We see this in history . . the Mammoths were frozen instantly in the process of eating . . obviously something drastic and cataclysmic happened - they went from warm (green vegetation) to instant frozen . . .
Before this, and even after this (even though the Mammoths proved this isn't true) we were taught that these things happened gradually -over very long spans of time . . Obviously they don't necessarily . .
So a "cooling" trend" or "warming" trend has to be looked at as part of a larger picture. The earth is experiencing tempuratures that have approached peak tempuratures seen in its entire global history. This says to me that something is going on, an we should be paying close attention. You are looking at 2 incidents in incredibly close time frames . . . They, coupled with so many other "incidents" of various natures, give me reason to pause . . .
