Experiment is first to simulate warming of Arctic permafrost
Although vegetation growth in the Arctic is boosted by global warming, it's not enough to offset the carbon released by the thawing of the permafrost beneath the surface, University of Florida researchers have found in the ...
Arctic development 'a new menace to polar bears'
Oil exploration and increased sea traffic in the Arctic are encroaching on polar bear habitat, adding to the existing climate change risk, representatives of Arctic nations said at a Moscow conference Wednesday.
Storing carbon in the Arctic
For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007, scientists observed nearly 50 percent less summer ice than had been seen in 1980.
Ex-NASA expert issues call for climate solutions
Longtime NASA expert James Hansen has issued a call for new approaches to stop global warming, saying solutions are needed and that currently accepted targets are too dangerous.
Arctic study shows key marine food web species at risk from increasing carbon dioxide
A research expedition to the Arctic, as part of the Catlin Arctic Survey, has revealed that tiny crustaceans, known as copepods, that live just beneath the ocean surface are likely to battle for survival ...
Researchers find significant amount of methane escaping East Siberian Arctic Shelf
Greenland's shrunken ice sheet: We've been here before
Think Greenland's ice sheet is small today? It was smaller—as small as it has ever been in recent history—from 3-5,000 years ago, according to scientists who studied the ice sheet's history using a new ...
Facebook warms - most - hearts in chilly Swedish city
Few people have heard about the town of Luleaa, but if they are Facebook users, chances are their pictures, status updates and "likes" have passed through this Swedish port near the Arctic Circle.
Global warming in the Canadian Arctic
Ph.D. student Karita Negandhi and professor Isabelle Laurion from INRS'Eau Terre Environnement Research Centre, in collaboration with other Canadian, U.S., and French researchers, have been studying methane emissions produced ...
Underwater 'tree rings': Calcite crusts of arctic algae record 650 years of sea ice change
Almost 650 years of annual change in sea-ice cover can been seen in the calcite crust growth layers of seafloor algae, says a new study from the University of Toronto Mississauga (UTM).
2013 marked by 'record sea level, weather extremes'
Sea levels this year posted a record high, making low-lying coastal populations ever more vulnerable to extreme weather like super-storm Haiyan, the UN said Wednesday.
'Missing heat' discovery prompts new estimate of global warming
An interdisciplinary team of researchers say they have found 'missing heat' in the climate system, casting doubt on suggestions that global warming has slowed or stopped over the past decade.
Research shows mercury may biomagnify more effectively in northern regions
Mercury biomagnification rates in aquatic Arctic ecosystems are higher than in lower latitudes, says a new study from Queen's researcher Raphael Lavoie.
Diatom algae populations tell a story about climate change in Greenland (w/ Video)
Researchers try to determine how much this "canary in a coal mine" can say about the impact of a warming climate on the Arctic region.
