Are new peatlands emerging in the Arctic?
Favored by climate change, more peatlands could develop in the Arctic, which in turn could sequester more carbon dioxide and thus mitigate the greenhouse effect.
Atmospheric rivers led to ice shelf collapse
The trigger of the collapse of the two smaller parts A and B of the Larsen Ice Shelf was, according to the latest findings, warm and humid air currents.
Lots of ice, lots of penguins – and vice versa
Where there is still sufficient sea ice along the Antarctic Peninsula, Adélie penguin populations are also stable. Where it is now too warm, unfortunately not.
Larsen-C ice shelf most threatened by solar radiation
Scientists from the British Antarctic Survey identified the factors that play the most important role in the melting processes of the ice shelf.
Will Arctic animals survive climate change?
Although no living thing is spared from climate change, Arctic wildlife is the most vulnerable. The Earth is warming 2.5 times faster than other parts of our planet.
Arctic ice melt may have less impact on ocean circulation
Freshwater carried into the Atlantic by melting Arctic ice may have a smaller impact on the global conveyor belt of ocean currents.
How meltwater and calving are linked at Helheim Glacier
Freshwater plumes of meltwater off the calving front apparently prevent large icebergs from calving as long as they persist.
Solid aerosols could affect climate in the Arctic
Rapid ice loss in the Arctic is creating more and more open water, which emits more gases and aerosols that affect the climate.
First collapse of an ice shelf in East Antarctica
Compared to West Antarctica, climate change has had little impact on East Antarctica. But this could now be over.
Heatwaves over polar regions baffle experts
At both ends of the globe, heat waves with temperature differences of up to 40°C above average have completely surprised and amazed experts.
Peatland permafrost closer to tipping point than assumed
Peatlands in the Arctic permafrost belt are responding more strongly to warming than previously thought.
The secret heat of Greenland’s glaciers
One of the world’s largest chunks of ice is generating incredible amounts of heat
Arctic Council approves Russian biosecurity project
Russia, as chair of the Arctic Council, has proposed a project to combat viruses that have been hidden under the permafrost for more than 30,000 years.
MOSAiC expedition provides deep insights into the Arctic of tomorrow
Only about one and a half years after the largest Arctic research expedition ever, the scientists provide a complete picture of climate processes in the Central Arctic for the first time.
Yedoma permafrost could release more CO2 than assumed
Very old carbon stocks in permafrost that have not been adequately accounted for could further accelerate global warming.
Possible explanation for paradoxical sea ice behavior around Antarctica
A new study shows that ocean eddies may be the reason why Antarctic sea ice is not behaving as climate models predict.
Antarctic Quest 21 expedition team evacuated by Swan Hellenic
The pandemic almost prevented the eight-man expedition team from returning from the Antarctic Peninsula – rescue came from an expedition tour operator.
Southern Ocean releases carbon dioxide during storms
The amount of carbon dioxide that is released back into the atmosphere by storms has significance in global climate change, according to a new study.
Greenland’s ice sheet has a delayed response to climate change
AWI researchers model how climate change has altered the ice sheet over the past thousand years and could affect it in the future.
Thawing permafrost is undermining Arctic infrastructure
Dealing with it will be hugely expensive
New search for Shackleton’s “Endurance” to start soon
In early February, the “Endurance22” expedition departs from Cape Town in a renewed attempt to locate and investigate the wreckage of the lost ship.
“Boaty McBoatface” takes a close look at Thwaites glacier
A fleet of autonomous underwater vehicles will collect important data under and around the fragile glacier in Antarctica over the next two months.
Heat wave leads to mass die-off of Magellanic penguins
As a result of extreme heat with temperatures of 44°C, hundreds of Magellanic penguins died near Punta Tombo in Argentina in January 2019.
The migrations of Arctic Jaegers connect the world
In the Canadian Arctic they breed together in the same spots, but after the breeding season the three smallest Stercorarius species take completely different routes.
