huh? 89 years is outrageous? 89 years is nothing. Is it outrageous every time we see Haley's comet every 76 years? It's mankind's ability to grasp geologic time that's outrageous. (myself included...like our national debt, these numbers are so big they become meaningless to us)Global Warming and Global Cooling have happened before, and there's growing evidence that they happened relatively quickly. I remember watching a show on the canyons in the west. The current theory is that it was created in a very short period of time. Perhaps a number of hours, created when frozen lakes (think dams of ice) melted and caused bodies of water the size of seas (filled with ice chunks) to rush down the landscape.

DNA extracted from ice cores shows that moths and butterflies were living in forests of spruce and pine in the area between 450,000 and 800,000 years ago. ..
"We have shown for the first time that southern Greenland, which is currently hidden under more than 2km of ice, was once very different to the Greenland we see today," said Professor Eske Willerslev from the University of Copenhagen, Denmark, and one of the authors of the paper.
"What we've learned is that this part of the world was significantly warmer than most people thought," added Professor Martin Sharp from the University of Alberta, Canada, and a co-author of the Science paper...Studies suggest that even during the last interglacial (116,000-130,000 years ago), when temperatures were thought to be 5C warmer than today, the ice persevered, keeping the delicate samples entombed and free from contamination and decay.
