Really don't understand why this is a tipping point? Earth's massive ice isn't just about sea level rise, they mitigate climate.

This is an enormous piece of ice that no longer mitigates the climate, but, adds to sea level rise.

The glacier is at the end of the Northeast Greenland Ice Stream, where it flows off land and into the ocean. Scientists with National Geological Survey see it as evidence of rapid climate change leading to the disintegration of the Arctic's largest remaining ice shelf.

A 44-square-mile chunk of ice, (click here) about twice the size of Manhattan, has broken off the Arctic's largest remaining ice shelf in northeast Greenland in the last two years, leaving scientists fearful over its rapid disintegration.

The territory's ice sheet is the second biggest in the world behind Antarctica's, and its annual melt contributes more than a millimeter rise to sea levels every year.

"We should be very concerned about what appears to be progressive disintegration at the Arctic's largest remaining ice shelf, because upstream ... is the only major Greenland ice sheet ice stream," said Jason Box from The Geological Survey of Denmark and Greenland (GEUS) in a statement on Monday.

"These last two summers have been exceptionally warm," Box said, speaking to CNN Monday....
