The Big Thaw

The big thaw
Global disaster will follow if the ice cap on Greenland melts. Now scientists say it is vanishing far faster than even they expected.

Greenland's glaciers have begun to race towards the ocean, leading scientists to predict that the vast island's ice cap is approaching irreversible meltdown, The Independent on Sunday can reveal.

Research to be published in a few days' time shows how glaciers that have been stable for centuries have started to shrink dramatically as temperatures in the Arctic have soared with global warming. On top of this, record amounts of the ice cap's surface turned to water this summer.

The two developments - the most alarming manifestations of climate change to date - suggest that the ice cap is melting far more rapidly than scientists had thought, with immense consequences for civilisation and the planet. Its complete disappearance would raise the levels of the world's seas by 20 feet, spelling inundation for London and other coastal cities around the globe, along with much of low-lying countries such as Bangladesh.

More immediately, the vast amount of fresh water discharged into the ocean as the ice melts threatens to shut down the Gulf Stream, which protects Britain and the rest of northern Europe from a freezing climate like that of Labrador.

The revelations, which follow the announcement that the melting of sea ice in the Arctic also reached record levels this summer, come as the world's governments are about to embark on new negotiations about how to combat global warming. [...]
OK, one comment: oh shit.
