Fossil tree shows consequences of magnetic pole reversal
A collapse of the Earth’s magnetic field, caused by the reversal of the magnetic poles, caused mass extinctions and climate changes 42,000 years ago.
Current weather anomalies find their origin in the Arctic
A weakening of the Arctic polar vortex has caused weather turbulence in the northern hemisphere since the beginning of the year.
Global ice loss corresponds to IPCC worst-case scenario
Globally, ice loss has been accelerating since the 1990s, and more than half of it has occurred in the northern hemisphere.
Next iceberg on the way soon
Recent satellite photos give reason for the formation of an iceberg the size of New York. The ‘calving’ of the iceberg seems inevitable. The only question is: when?
Iceberg A68 off South Georgia breaks apart
Iceberg A68 drifted close to the island of South Georgia and supposedly threatended the local wildlife. Latest satellite images show that the giant disintegrated into unproblematic fragments.
Drift ice stations are Russian tradition
The self-propelled polar platform “Severny Polyus” was launched in St. Petersburg on Friday, December 18, 2020.
Iceberg A-68a on collision course with South Georgia
In January 2021, a research mission will be launched to determine the impact of the giant A-68a iceberg on the island of South Georgia, one of the world’s most important ecosystems.
Eye in the sky points to global permafrost thaw
A new 21-year series of satellite imagery data shows the progression of permafrost retreat and points to climate change as the cause.
Greenland ice sheet melting faster until 2100
The Greenland ice sheet will melt about 60 percent more by 2100, causing sea levels to rise more sharply.
Global warming causes gigantic damage
Global warming is showing its dramatic effects. The direct damage from warming in the Russian Arctic could be around 100 billion euros.
Water in the glacial cellar – A journey into the depths brings new insights to the surface
Glaciologist Andreas Alexander shows with his painstakingly won data how profound the current changes are for the glaciers of Spitsbergen.
Permafrost soils continue to thaw
The permafrost in the Arctic is thawing on a frightening scale. Researchers at the AWI have impressively confirmed this by analysing satellite images.
“Sentinel 6” on the road for climate change
The research satellite “Sentinel-6” is intended to observe the oceans of the earth and accurately map and document the impacts of climate change.
From White to Blue
The cause of the speed and severity of abrupt climate changes during the last cold period lies in the ocean. This is confirmed by a new study by the AWI.
Research agreement between Switzerland and Australia
An agreement between Australia and Switzerland on Antarctic research aims to strengthen cooperation
Gigantic iceberg is heading for South Georgia
South Georgia may face a collision with the world’s largest iceberg, A-68A, if it does not change course for the last 500 kilometers.
One of the largest ozone holes in years
The hole in the ozone layer above Antarctica is one of the largest and deepest in the last 15 years, according to the World Meteorological Organization (WMO).
Arctic sea ice still not forming
The formation of Arctic sea ice has been lagging behind normal since its minimal expansion, and many areas are still ice-free.
Friendship between polar bears and walrus
Polar bears have begun to invade colonies of walruses, which no longer show fear when polar bears are near them.
More ice and yet rising sea levels due to melting ice sheets
Antarctica’s melting ice sheets could lead to more pack ice, but also to faster sea level rise.
Saving the Arctic sea ice with glass beads?
The Arctic Ice Project aims to prevent sea ice in the Arctic from melting by using silica pellets that reflect sunlight.
Young people from Nunavut make documentary on climate change
The effects of climate change, which residents of Arctic communities are already experiencing, will be captured by young people in a documentary.
Sea otters vanish followed by an ecosystem collapse
The delicate underwater ecology of the Aleutian Islands in Alaska suffers twofold from the decline of the otters in the face of climate change.
Thawing permafrost soils release mercury
Permafrost soils not only store large amounts of carbon dioxide and methane but also mercury. A recent study has now quantified its release in the Yukon region of Alaska.
