Methane emissions from Arctic tundra increase when sea ice melts, according to a new study from Lund University in Sweden. This connection has been suspected before, but has lacked strong evidence until now.
According to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began.
In the Arctic, sea ice is melting and leaving larger sections of ocean exposed to air and sun. This phenomenon could fuel increased evaporation, leading eventually to more precipitation in far-north latitudes.
Researchers from the University of Aberdeen are set to investigate what consequences the rapidly shrinking sea ice cover in the Arctic is having on the marine ecosystem.
The current El Nino weather pattern may be on track to become one of the strongest in more than half a century, experts at the World Meteorological Organization said Tuesday.
On both sides of the Bering Strait, summer sea ice has once more dropped to a level that is driving thousands of walruses onto coastal beaches.
Russia pressed a claim at the United Nations Tuesday for an additional 1.2 million square kilometres (463,000 square miles) of Arctic shelf, stepping up a race for the region's hydrocarbon and mineral wealth.
Not so long ago, skeleton staff overwintering at the Ny-Alesund research centre could walk on the Arctic town's frozen bay and race their snow mobiles across its surface.
The planet just set another monthly climate record with the hottest June in 135 years, US government scientists said Monday.
The volume of Arctic sea ice increased by a third after the summer of 2013 as the unusually cool air temperatures prevented the ice from melting, according to UCL and University of Leeds scientists. This suggests that the ...
