NOTE ON POPULAR POSTS

You can see the titles in capitals at the start of each snippet. (It would be nice if Blogger introduced an upgrade program that could fix this little problem.)

SMALL AMOUNT OF WARMING COLLAPSES ICE-SHELVES

An analysis of prehistoric 'Heinrich events' that happened many thousands of years ago, creating mass discharges of icebergs into the North Atlantic Ocean, make it clear that very small amounts of subsurface warming of water can trigger a rapid collapse of ice-shelves. The findings provide historical evidence that warming of water by 3-4 degrees was enough to trigger these huge, episodic discharges of ice from the Laurentide Ice Sheet in what is now Canada, and raise serious concerns about Antarctic ice sheets.
