NASA: Isarna smälter fort

På bloggen Living the Scientific life rapporteras det om att NASA har studier på att isarna smälter snabbare än väntat.

Two studies were recently published, documenting changes in the Antarctic and Greenland ice sheets, confirming that climate warming is changing how much water remains locked in Earth’s largest storehouses of ice and snow (Greenland pictured at top and right).

As if there could be any doubt regarding their conclusions, NASA recently published a satellite study of both regions and goes so far as to directly tie these changes to global warming, describing the survey as ”the most comprehensive” ever for both regions.

Based on satellite mapping of ice sheets, published in the peer-reviewed Journal of Glaciology, the survey validated computer models projecting the effects of global climate change on Earth. In the NASA press release, the study’s lead author, Jay Zwally said of the data;

If the trends we’re seeing continue and climate warming continues as predicted, the polar ice sheets could change dramatically. The Greenland ice sheet could be facing an irreversible decline by the end of the century.
