Our new research shows the island's largest glaciers are losing ice faster than previously thought.
The pattern of autumn sea ice growth has been completely disrupted. The director of the National Snow and Ice Data Center explains what's happening.
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.
Arctic heat waves were once rare and unusual events. But as their intensity and frequency increase with climate change, their fallout could affect the north — and the planet — for decades to come.
This is the story of 'Misha', as I have come to know her. Both I and my research have been deeply affected by a polar bear I have never met face to face.
Climate change is thawing permafrost and increasing the risk of these accidents, and the region has fewer of the bacteria that can 'clean up' oil spills.
As climate change warms northern rivers and changes precipitation patterns, some types of cold-loving fish are failing.
As snow melts and landscapes change, there will be winners and losers.
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.
