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.
Global change: Stowaways threaten fisheries in the Arctic
Just think of the warty comb jelly or sea walnut, as it is also known. It has caused tremendous damage to fisheries in the Black Sea after arriving in ballast water from its original habitat along the East ...
NASA begins airborne campaign to map greenland ice sheet summer melt
For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt.
Testing a relationship: Arctic warming and China's summer monsoon
(Phys.org) —In the late 1970s, eastern China experienced a shift in the summer monsoon circulation causing a "North-drought/South-flood" trend. In two related studies, researchers at Pacific Northwest National ...
Thawing permafrost: The speed of coastal erosion in Eastern Siberia has nearly doubled
The high cliffs of Eastern Siberia – which mainly consist of permafrost – continue to erode at an ever quickening pace. This is the conclusion which scientists of the Alfred Wegener Institute, Helmholtz ...
Melting Arctic sea ice could increase summer rainfall in northwest Europe, study reports
A new study offers an explanation for the extraordinary run of wet summers experienced by Britain and northwest Europe between 2007 and 2012. The study found that loss of Arctic sea ice shifts the jet stream ...
Study shows unprecedented warmth in Arctic
(Phys.org) —The heat is on, at least in the Arctic. Average summer temperatures in the Eastern Canadian Arctic during the last 100 years are higher now than during any century in the past 44,000 years and ...
