This started as a response, but quickly became a place I could put some of the sites on the Antarctic I have found, used or read over the last few years while reviewing this topic:
The West Antarctic Ice Sheet is called the Godzilla of Global Warming. If it breaks, you can see a 15-20 feet increase in world wide ocean levels within days. Remember Ice Sheets are
This is believed to have occurred about 120,000 years ago in what is called the "Mad house Century":

Please note this is highly unlikely and even with the worse case scenario of global warming will take centuries, I just put it here to show how much of Antarctica is the West Antarctic Ice Sheet.
