Russia’s invasion of Ukraine upended Olga Shpak’s life — and a generation of science.

The algae Melosira arctica is the foundation of the food chain, and its contamination could have major consequences for ecosystems and the climate.

Roughly three-quarters of the residents of Nuiqsut, which sits in the centre of Alaska’s North Slope some 20 miles south of the Arctic Ocean, mostly eat foods harvested from the wild.

As ice melts, navigable routes have opened in ways that were not expected until the middle of this century.

Russian scientists are being barred from international collaborations, including at-sea surveys and scientific conferences.

As more people push into once-remote areas, truly quiet spots — devoid of the noise of traffic or crowds of tourists — have become increasingly scarce. Now, a coalition of activists, scientists, and park officials are trying to preserve the last quiet places on the planet.

The Arctic - "ground zero for climate change” — is warming more rapidly than the rest of the planet because of a positive feedback loop called Arctic amplification.

The Arctic Ocean could absorb 20 per cent more carbon than previously predicted before the end of the century, according to a recent study.

The top of the world is turning upside down, says the first overall assessment of Canada's Arctic Ocean.

The House approved legislation on Wednesday, September 11, 2019, that would permanently bar drilling off the Atlantic and Pacific coasts and extend a moratorium on drilling off Florida's west coast.

One minute, it was dangling off the back of an icebreaker into the waters of the High Arctic. The next, the crucial piece of gear was gone.
