Research shows ice sheets as large as Greenland's melted fast in a warming climate
November 10, 2017
New research published in Science shows that climate warming reduced the mass of the Cordilleran Ice Sheet by half in as little as 500 years, indicating the Greenland Ice Sheet could have a similar fate.
The Cordilleran Ice Sheet covered large parts of North America during the Pleistocene - or Last Ice Age - and was similar in mass to the Greenland Ice Sheet. Previous research estimated that it covered much of western Canada as late as 12,500 years ago, but new data shows that large areas in the region were ice-free as early as 1,500 years earlier. This confirms that once ice sheets start to melt, they can do so very quickly.
