The Arctic is warming about twice as fast as the planet as a whole, with serious consequences. Scientists have been warning about this for decades.
Models have predicted for some time that with every degree of global warming, the Arctic will see double or more.
The wet and low-lying East Siberian Arctic is likely to be a major methane source in the coming decades.
Arctic cod are key prey for seals, whales and seabirds. What happens when ship noise drives them away?
The next federal budget will be decisive for Canada’s North. Will the government put in the money to achieve its many priorities in the Arctic?
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.
