What happens when you place a couple of pieces of ice into your glass of water?
The Antarctic’s Ice Sheet is 5.4 million square miles and Greenland’s Ice Sheet is 656,000 square miles.
If Greenland’s Ice sheet melted, (moved from land into the ocean), the world wide sea level would rise 20 feet. If the Antarctic’s Ice sheet moved from land to the ocean through melting, the oceans would rise 200ft.
The Antarctic’s Ice Sheet is melting into the ocean much faster than scientist’s previously believed due to warm water eating away at it from below.
The Arctic Ice is already in the sea and therefore will not have any effect in displacing the oceans’ sea level. However the Arctic acts like a huge freezer maintaining Greenland’s Ice Sheet and when that goes, so does Greenland.
Given the inaccurate predictions by scientists over the years it wouldn’t be a surprise to this writer if 10% of Greenland slides into the ocean within the next three years causing a sea level rise of 2ft. This intern sloshes up onto Antarctica resulting in 10% of Antarctica’s Ice Sheet disintegrating into the ocean resulting in another 20ft rise in world wide sea level by 2016.
100 square miles of ice falls off Greenland and melts into the ocean.
Should a large portion of Greenland or Antarctica go the rise in sea level could happen suddenly.
