On: Massive glacier collapse

[Shivetya]

http://www.bbc.co.uk/news/science-environment-21231380 is the article I read before, specifically the paragraph above a picture of the landmass which starts with the words "Indeed, satellite measurements"

The water moves underneath the sheets causing them to move, this movement has to be part of the reason if not the entire reason sheets fracture.

I am far more the believer that was is under the ice sheet has more affect than what is above it
