NASA to investigate climate impacts of Arctic sea ice loss
A new NASA field campaign will begin flights over the Arctic this summer to study the effect of sea ice retreat on Arctic climate. The Arctic Radiation IceBridge Sea and Ice Experiment (ARISE) will conduct ...
Snow has thinned on Arctic sea ice
From research stations drifting on ice floes to high-tech aircraft radar, scientists have been tracking the depth of snow that accumulates on Arctic sea ice for almost a century. Now that people are more ...
Finding the deepest iceberg scours to date provides new insights into the Arctic's glacial past
Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have found between Greenland and Spitsbergen the scours left behind on the sea bed by gigantic icebergs. ...
Canada launches mission to map, claim North Pole
A scientific mission to map the seabed surrounding the North Pole got underway Friday amid Canada's push to claim the area and surrounding Arctic waters ahead of Russia and others.
Huge waves measured for first time in Arctic Ocean
As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before the middle ...
Has Antarctic sea ice expansion been overestimated?
New research suggests that Antarctic sea ice may not be expanding as fast as previously thought. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a processing ...
World is getting warmer, says global climate report (Update)
The world is getting warmer, as greenhouse gases reach historic highs and Arctic sea ice melts, making 2013 one of the hottest years on record, international scientists said Thursday.
Climate-cooling arctic lakes soak up greenhouse gases, study finds
New University of Alaska Fairbanks research indicates that arctic thermokarst lakes stabilize climate change by storing more greenhouse gases than they emit into the atmosphere.
Norwegian reindeer herds boosted by climate change
Researchers say climate change isn't threatening reindeer on the Norwegian high arctic archipelago of Svalbard.
Tech woes menace Canada's Arctic maritime traffic: union
Technical problems with a new Canadian Coast Guard communications system are putting maritime traffic in the country's Arctic at risk, a union official said Tuesday.
NASA's high-flying laser altimeter to check out summer sea ice and more
Sea ice in summer looks dramatically different than sea ice in winter, even in the polar Arctic. Summer snowmelt, pools of water on thinning ice and exposed ocean replace vast winter expanses of white snow-covered ...
Leading scientists express rising concern about 'microplastics' in the ocean
Microplastics – microscopic particles of plastic debris – are of increasing concern because of their widespread presence in the oceans and the potential physical and toxicological risks they pose to organisms.
Polar bears from space
Polar bear population estimates based on satellite images are similar to aerial estimates, according to a study published July 9, 2014 in the open-access journal PLOS ONE by Seth Stapleton from United States ...
Shark teeth analysis provides detailed new look at Arctic climate change
A new study shows that some shark species may be able to cope with the decreasing salinity of Arctic waters that may come with rising temperatures.
