Sea-level rises 'may not be as high as worst-case scenarios have predicted'

New research suggests Greenland's glaciers are slipping into the sea more slowly than previously thoughtSea-level rises are unlikely to be as high as worst-case scenarios have forecasted, suggests new research which shows that Greenland's glaciers are slipping into the sea more slowly than was previously thought. But the scientists warned that ice loss still sped up by 30% and is driving rises in sea levels that endanger low-lying coasts around the world.Along with Antarctica, the loss of ice from the huge Greenland ice cap is the biggest direct contributor to rising sea levels, pouring 250bn tonnes of water into the oceans each year. But the complexity of glacier dynamics has meant predictions of future losses as the global warming continues have been wide-ranging and controversial. The new work used for the first time satellite data to track the progress of over 200 individual Greenland glaciers between 2000 and 2010."Previous...
