Emperor penguins – call for classification as “threatened” species
Antarctic sea ice is shrinking and numerous emperor penguin colonies are losing their habitat, prompting an official proposal in the U.S. to list the species as “threatened”.
Antarctic Circumpolar Current picking up speed
Contrary to earlier assumptions, climate change does have an impact on the circumpolar current that surrounds Antarctica.
Arctic Hub – A bridge between research and society in Greenland
The International Arctic Hub platform has been active for about a year and went online with its new website a few days ago.
Male Antarctic fur seals spend winter in Antarctica
Juvenile fur seal males eat so much Antarctic krill in winter that this amount should be considered in the management of the krill fishery.
Antarctic ice sheet destabilized within a decade
Since the last ice age, the Antarctic ice sheet has lost huge amounts of ice several times in a very short period of time, a new study now shows.
Greenland’s glacial silt, an answer blowing in the wind
Plumes of dust from Greenland heralding the coming of winter are made up a material that scientists say can be used elsewhere
Acoustic differentiation of belugas and narwhals
The sounds of belugas and narwhals are very similar and difficult to distinguish. Researchers have now found that the echolocation clicks of the two species show significant differences.
Antarctic seals affected differently by climate change
Weddell seals do not yet appear to be much affected by climate change, while crabeater seals are more likely to suffer as warming continues.
Black carbon from forest fires contributes to Arctic warming
A new study shows that the concentration of black carbon in the Arctic is strongly correlated with forest fires occurring at mid-latitudes.
Thawing permafrost poses some dangers
If the permafrost around the polar ice caps thaws, viruses and antibiotic-resistant bacteria, as well as chemicals of concern, could be released.
Deep freezing to stabilize melting permafrost
Global warming and rising temperatures in the Arctic are causing permafrost to thaw, causing major problems for cities north of the Arctic Circle.
Climate change affects the diet of polar bears
To document the change, researchers examined the fatty tissue of polar bears to determine how their diets have changed.
“A World Without Ice”
With numerous events, the Geneva Cryosphere Hub forms a bridge from Switzerland to the climate conference in Glasgow.
AWI offers expert service for the UN Climate Change Conference
The Alfred Wegener Institute is represented at the COP26 by several researchers, who will give presentations on the thawing of permafrost and on polar oceans, among other topics.
Scientists discover large Arctic polynya
In May 2020, a 3,000 square kilometre hole, known as a polynya, had opened up in the ‘Last Ice Area’ north of Greenland and Ellesmere Island.
Citizen Scientists wanted for walrus census
The British Antarctic Survey and WWF are looking for citizen scientists to help protect walruses by assisting with a population census.
DEEPICE network launches collaboration
New European research and education network launches collaboration to uncover past climate changes in Antarctica.
McMurdo Ground station supports new Landsat 9 satellite
The new satellite’s communications are run through NASA’s ground station at the U.S. McMurdo Research Station in Antarctica.
Decrease in slush causes Antarctic ice shelves to calve faster
In a new study, researchers found that cracks in the ice shelf are held together by a slurry of ice, snow and frozen seawater. However, this ice melange has been declining for decades.
A climate factor causes mass mortalities among Arctic birds
Bird die-offs seem not to be common, but in the Bering region these dramatic events in the wild have been occurring over the past few years on a regular basis.
It has never been so cold at the South Pole
While in the Northern Hemisphere last summer saw record high temperatures and forest fires in Siberia, it had never been so cold before at the South Pole.
Norwegian cave holds 100,000 year old polar bear bones
New archaeological finds of bone material from a cave system provide evidence that large mammals lived in northern Norway during the Ice Age.
First complete count of Weddell seals
Citizen scientists helped American researchers estimate the global population of Antarctic Weddell seals for the first time using satellite imagery.
Annual sea ice minimum in the Arctic
Sea ice extent in the Arctic Ocean reached its annual minimum of 4.81 million square kilometers on September 12, 2021. This puts the year in twelfth place on the negative list of absolute values.
