Nearly 60 years after a radiation-leaking reactor was removed from a US Army base on the Greenland ice sheet, the military is exploring portable nuclear reactors again.
Glaciers aren't sterile wastelands – they're chock-full of microscopic life.
New research shows how fibre-optic cables can monitor the hidden structure of glaciers, teaching us about past and future ice flow.
Russia is attempting to claim more of the Arctic seabed, an area rich in oil, gas and minerals. It’s also expanding shipping and reopening Arctic bases. Here are two things the U.S. can do about it.
This ancient ecosystem showed that the ice sheet had melted to the ground
in northern Greenland within the past million years.
Our new research shows the island’s largest glaciers are losing ice faster than previously thought.
Greenland’s glaciers have retreated so far that they can no longer support the ice sheet that feeds them. The ice sheet system has reached a new normal of consistent annual ice loss.
Extreme shrinkage of summer sea ice is just the latest evidence of rapid Arctic warming – and what happens in the Arctic doesn’t stay there.
The “last glacial period” saw huge, rapid climate changes. Our new research found they happened all around the world, and each time within just a few decades.
Satellite research confirms its enormous ice sheet is melting faster than most scientists predicted.
Antarctica is no longer the sleeping giant of sea level rise. New research delved into the past and found when the Earth warms, its ice sheets can melt extremely quickly.
Rising sea levels, unstable weather, and a much smaller carbon budget.
Greenland and Denmark have a complicated history, but the connection runs deeper than economic convenience.
The USA has a long colonial history – as does Denmark. The USA has even tried to buy Greenland before. But this time, Greenland isn’t Denmark’s to sell.
In 1867, the US bought Alaska from Tsar Alexander II for a tidy sum of $7.2 million. Trump probably wouldn’t be able to get that kind of bargain for Greenland.
A researcher based in Fairbanks, Alaska, links 2019’s record-breaking wildfires in far northern regions of the world to climate change, and describes what it’s like as zones near her city burn.
Greenland’s ice made headlines in June, as warm weather made for unseasonably widespread melting. And though this summer is still unfolding, the human fingerprint on Greenland’s ice can’t be denied.
Sea levels could rise by two metres by 2100, sparking a refugee crisis unlike anything the world has ever seen.
Climate scientist predict that the combined effect of ice loss in Greenland and Antarctica will be more extreme weather, with impacts on agriculture, infrastructure and human life itself.
Meteorite impacts have fundamentally shaped the history of our planet.
