Ice Mass

• The Greenland and Antarctic ice sheets have shrunk in both area and mass. Data from NASA JPL's Gravity Recovery and Climate Experiment show Greenland lost 150 to 250 cubic kilometers of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers of ice between 2002 and 20054.

• Mountain glaciers and snow cover have declined on average in both hemispheres, and may disappear altogether in certain regions of our planet, such as the Himalayas, Australian Alps or the Kilimanjaro, by 2030.

• Sea ice melt is a clear evidence that the sea and atmospheric temperature are warming

• When sea ice melts it does not contribute to global sea level rise, however land ice directly contributes to a rise in sea level when melting.

• There are 5-6 meters worth of sea level in the Greenland ice sheet, and 6-7 meters in the West Antarctic Ice Sheet6 which is of great concern if there were to melt (which has already began)
