The West Antarctic ice sheet collapsed periodically between 3 million and 5 million years ago, adding more than 16 feet to global sea level, according to the first examination of soil cores far below the surface of the Ross ice shelf.
Also, new computer models suggest that warmer waters nearby attacked the ice from below, triggering those collapses.
Both findings appear in studies published Thursday in the journal Nature.
"What we're seeing in the past would lead us to believe that we are on track for losing parts of the West Antarctic ice sheet," said Tim Naish, director of the Antarctic Research Centre at Victoria University in New Zealand and leader of the study that looked at dirt cores.

I'm about 600 ft above sea level, and in about the middle of the continent. I would think I'm ok. But those of you on coastlines, and New Orleans, might want to move at some point.

I said that regardless of what you believe, it is scary news.
I'm not sold on it being man-made.....
Thats why I put this article on here; due to the data regarding melting over a 40,000 year time scale as well as the correlation to shifts of the axis.
In fact, if one wanted to do so, they could interpret this data as evidence against man-made global warming.
So no, I am not turning this article or the data contained therein to any sort of man-made evidence.
