New research finds that chlorofluorocarbons (CFCs) and other ozone-depleting substances have boosted the effects of climate change in the Arctic.
Hundreds of thousands of lakes, rivers and streams in the Arctic exist only because of the permafrost that lies beneath them. The warming Arctic threatens to change that.
The long tusk of the male narwhal earned these whales their fanciful nickname. But there's more to these Arctic mammals than their unique spiral tooth.
Warm summers aren't the only threat to Arctic ice – increasingly intense winter storms are also weakening and reducing ice cover.
More than 600 experts will spend the next year drifting in Arctic waters to gain a better understanding of how climate change is affecting the region and how it can be fought.
Rising sea levels, unstable weather, and a much smaller carbon budget.
Levels of microplastics in the ocean are rising. More study is needed to figure out how these microplastics affect the qualities and properties of sea ice, and what the potential impact may be.
The eastern Arctic and sub-Arctic marine areas of Canada are changing rapidly under climate change.
Coastal communities are helping scientists understand the impacts of marine heatwaves — and find solutions.
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.
The winter of 2018-19 claimed 200 reindeer in Svalbard, Norway, according to a recent census.
Some 58 metres of sea level rise is locked up in Antartica's ice sheets, and it's melting faster than expected.
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.
Algae at the bottom of the Arctic food chain relies on sea ice.
A scientist explains how global warming is affecting the entire world – from the mountains, to the sea.
In May 2019, Canada made a partial submission to the United Nations on the limits of its extended continental shelf in the Arctic.
With global warming, underwater Arctic kelp forests are proliferating, and might be a potential resource.
Climate change has caused a 60-fold increase in active landslides on one Canadian Arctic island.
Antibiotic resistance is common in bacteria where there's a large human population and poor sanitation. For the first time however, it's been found in the remote Arctic.
All too often the Arctic region is portrayed as an area on the cusp of military invasion. This is an easy narrative to sell. But is there really a new Cold War coming?
