Among these animals is the Arctic hare, the largest hare in North America. The Arctic hare has large claws on all four feet, but the ones on its hind legs are unusually long, allowing it to dig into ...

Tundra plants absorb atmospheric carbon in the summer, when they use sunlight to photosynthesize, but they emit carbon dioxide in the winter, when the daylight is gone.

With the Arctic warming faster than the global average, researchers at UBC and the University of Edinburgh have made an important discovery about tundra plants and how they are adapting faster ...

Tundra plants can eke out an existence in the very short summers of the Canadian High Arctic such as here on Ellesmere Island, Nunavut. Photo credit: Anne Bjorkman.

Rapid climate change is upending established plant diversity and growth patterns in the Arctic, with species blooming in some areas and declining in others, suggests a study published today in the ...

Learn fascinating arctic fox facts and about their amazing adaptations that help them survive in one of the coldest places on the planet.

All living things have a blueprint provided by the DNA that is stored in every one of their cells. Yet the amount of DNA in ...

The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...

The Arctic tundra has historically helped reduce global emissions. But rising temperatures and wildfires in the region are changing that, scientists say.

Arctic tundra is releasing greenhouse gases into the atmosphere as hotter temperatures melt frozen ground and wildfires increase.

Arctic tundra, which has stored carbon for thousands of years, has now become a source of planet-warming pollution. As wildfires increase and hotter temperatures melt long-frozen ground, the ...
