Greenland Ice Melt Speeds Up Sea Level Rise
Water may be flowing from the Greenland ice cap and into the sea more quickly than anybody expected.
It doesn’t mean that global warming has got conspicuously worse: rather, researchers have had to revise their understanding of the intricate physiology of the northern hemisphere’s biggest icecap.
There is enough ice and snow packed deep over 1.7 million square kilometres of Greenland that, were it all to melt, would cause a rise in global sea levels of about six metres.
