Urgent call for more research in the Southern Ocean
The first international symposium on the Southern Ocean Observing System, held last week in Hobart, Australia, ended with an urgent call to significantly expand research in the Southern Ocean.
Northwest Territories in the grip of blazes
Wildfires continue to rage across Canada, forcing the evacuation of several cities. The Northwest Territories are particularly hard hit as is the boreal forest.
Below the ice, future natural areas to be preserved?
A joint team from the Franco-Swiss Alpine regions has published an article in Nature exploring the natural areas that will be exposed by retreating glaciers between now and 2100, calling for recognition of this unique character and the services these areas provide to humanity.
Was researching sediment transport – ended up getting cheap electricity for all of Greenland
In the 1970s, the geographer Bent Hasholt wanted to conduct research that mattered to society – so he started calculating rainfall in his free time.
Past and future of the Atlantic Meridional Overturning Circulation
The Atlantic Meridional Overturning Circulation plays a crucial role for the global climate. But since the early 2000s, it has been weakening, and there is growing concern about a possible collapse of the circulation system.
Krill – “The true cost of sustainable fishing should include investment in research”
Krill is fished by five countries in Antarctica, and other countries could have their sights on this enormous source of protein. Philip N. Philip N. Trathan, a biologist with 30 years’ experience in international committees dealing with this subject, shows how to maintain the principle of precaution, the cornerstone of this activity.
“Time-travelling” pathogens: science but no fiction
Thawing permafrost soils pose an immense source of ancient pathogens. Researchers have now concluded that such “time-traveling” pathogens pose a potential threat to present-day biological communities, as well as to humans.
Unpredictable spring disturbs species seasonal cycles
Plants and animals have to adapt year after year to an increasingly unpredictable spring, a new study shows.
New AI-assisted technology is planned to track permafrost in Alaska, beyond
Tracking changes in permafrost can take years and sometimes decades, lags that cannot keep up with the transformations in the rapidly warming Arctic. Now scientists will be developing new technology to track those changes in real time, thanks to a project funded by Google.
Can Arctic terns defy climate change?
Arctic terns, which fly from pole to pole and back again every year, may be able to compensate for some of the climate change impacts they face outside the breeding season.
When Greenland had melted
Vegetation traces found in an ice core taken nearly 60 years ago in the far north-west corner of Greenland suggest that the ice sheet had largely melted over 400,000 years ago.
Svalbard – A society in process and paradox
Svalbard is facing changes on multiple scales. An ethnological study analyzing this process, and the issues that come with it, has just been published.
A sea lily snatches a ride on a crab in the Svalbard fjords
From the deck of their magnificent sailing boat, in a breathtaking natural scenery, researchers are studying an opportunistic sea lily that hitchhikes on the back of a crab.
Heat waves in the Arctic Ocean
Many countries in Europe, parts of the USA and Canada, and also large parts of Russia are currently experiencing massive heat waves. Anyone thinking that a dip in the sea will cool things down will be disappointed, because the oceans are also affected by an unprecedented rise in temperature. Since May/June, this has been extending […]
Canada is burning, the Arctic is glowing red
The forest fires ravaging Canada have also reached the Arctic, raising questions about the consequences for this region already largely affected by global warming.
The Greenland paradox
One of the regions most affected by climate change is Greenland. Its mainly Inuit population is seeing the effects, but to the great surprise of a sociological survey, many are unaware of the causes and of human responsibility.
Huge ice krill melted for Antarctica’s protection
Weren Decker, also known as “Iceman,” sculpted a giant krill out of ice to draw attention to global warming and the climate crisis with his melting work of art.
Ukraine conflict keeps grip on Arctic research
Due to the Ukraine conflict and the boycott, the international research community lost access to the vast part of the Russian polar region.
Already extreme, Arctic weather is about to get a little worse
Climate change affects not only temperatures and ice but also weather conditions. Inhabitants of the Arctic should prepare for more extremes
Whales won’t be fixing the climate for us
Whales probably aren’t going to be able to help us sort out the mess we’ve made of the climate after all
What is an ice-free Arctic?
A recent paper has predicted the Arctic could be “ice-free” by 2030. But that’s not the same as saying there will be no ice at all. At least to to begin with
Even 1.5°C could be too high for 3.5 billion
Even if countries hit the lower target for temperature increases set by the Paris Agreement, it may not be enough to prevent some countries from suffering catastrophic damage caused by ice-sheet melting
The ocean lung is losing its air
Global warming is causing the mechanism that delivers oxygen-rich waters to the world’s oceans to break down faster than expected
Alfred Wegener’s legacy makes important contribution to modern climate research
Century-old data from Alfred Wegener’s Greenland expedition are helping scientists better understand climate change
