Greenland's 'grand canyon' was part of a large river system before an ice sheet covered it millions of years ago, a new study says. Now it appears to be a vital part of the island's plumbing.
Sea ice in the Arctic Ocean is likely to hit record lows next week, and then keep on melting, according to the US National Snow and Ice Data Center.
Fluctuations in ice melting over time in Greenland may mean that the trajectory towards a complete melt is less direct than previously thought. New research suggests that future sea level rise predictions should be made cautiously.
An ice island about twice the size of Manhattan broke away from Greenland's Petermann Glacier last week, but the calving was likely caused by ocean currents, not global warming.
A satellite photo reveals that the iceberg twice the size of Manhattan that recently broke away from the Petermann Glacier is now heading toward open waters.
The rapid melting of 97 percent of the surface of Greenland's ice sheet in just four days has left scientists puzzled.
An iceberg twice the size of Manhattan has broken away from the Petermann Glacier in northern Greenland, raising concerns about North Atlantic shipping lanes and oil platforms.
An iceberg twice the size of Manhattan has broken off from a north Greenland's glacier, raising concerns of global warming.
A NASA satellite has spotted An iceberg twice the size of Manhattan breaking away from a glacier in northern Greenland.
An iceberg twice the size of Manhattan has conformed to scientists' predictions by breaking free of its northern Greenland glacier.
