Greenland Glacier Speed Doubled in Past Five Years
A study published in Science magazine notes that Greenland's melting glaciers cause global sea levels to rise approximately 0.5 mm per year, and that overall sea levels are rising by 3 mm per year. Yearly ice loss from the glaciers has increased from 50 cubic kilometers in 1996 to 150 cubic kilometers in 2005.
In related research, scientists studying Mount Kilimanjaro in Kenya believe the loss of ice on its summit is accelerating as well, and may disappear entirely by 2020.
