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.
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.
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.
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.
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.

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.
Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.
With all eyes on China’s intentions in the Arctic, Singapore is flying under the radar. But the tiny Asian nation is also pursuing its own interests in the Arctic.
