Arctic lakes have two ways of emitting carbon dioxide
One of them is more troubling than the other
Alaska dinosaur fossils hint at a wetter, wilder future
Pre-historic Alaska appears to have experienced seasonal floods capable of overwhelming a grown dinosaur
Canada counts its Arctic seaweed before it changes
Global warming won’t mean the end of algae in Canada’s Arctic, but it will change the species found there
Thwaites glacier is a growing concern
A new study suggests that the glacier could retreat even faster in the future, with massive consequences for global sea levels.
Less sea ice — no more driftwood in Iceland?
Driftwood in the Arctic appears to be another victim of climate change. By 2060, sea ice could be gone and with it the means of transport for driftwood.
Arctic whales pushed north by climate change
Dwindling sea ice and rising ocean temperatures are depriving Arctic whale species of habitat and displacing them further north.
Warm Water Threatens East Antarctic Ice Sheet
Strong westerly winds and ocean currents bring warm water to East Antarctica and contribute to ice loss from ice shelves.
The Arctic is greening
Three doctoral students from ETH Zurich traveled to Svalbard in July to study the effects of climate change on Arctic vegetation.
Climate simulation suggests unexpected wildfire-sea ice connection
Everyone knows fire melts ice, but research seems to confirm that melting sea ice may also be contributing to the growing number of Northern Hemisphere wildfires
Arctic shrubs spreading slower despite climate change
Although conditions in the Arctic are becoming more favorable with warming, shrubs may not spread as fast as previously thought.
Aerosols in the Arctic play significant role for climate
Aerosols in the central Arctic play an important role in the formation of ice in clouds, with implications for climate.
Climate change might cause disease outbreak in Antarctic fish
Never before did scientists observe so many Antarctic fish with skin tumors
New study and map show reality of thawing permafrost
Two papers led by AWI summarize what is known about the effects of thawing permafrost in the Arctic and call for more action.
Antarctic glaciers are losing ice at fastest rate in 5,500 years
Uncontrolled ice loss from the two glaciers could contribute to sea level rise of up to 3.4 meters over the next few centuries.
Oxygen deficiency in the ocean – looking bleak for polar marine life
Is marine life facing a mass extinction? Our ability to drastically reduce greenhouse gas emissions will probably determine that.
Is there even less time left for the Paris climate goal?
Including all types of emissions shrinks the time to reach the 1.5 degree target.
Hyper-resistant bacteria discovered in Antarctica
The bacteria and genes found could pose a global health risk as climate change progresses.
Southern Ocean receives much more iron from anthropogenic sources
If the iron input to the Southern Ocean decreases in the future due to reduced carbon emissions, iron could become scarce.
Taiga could displace Siberian tundra almost completely
Only ambitious climate protection can preserve one-third of the tundra in Siberia, according to an AWI study.
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.
