Scientists have quantified how much climate change has driven the population decline of polar bears living in Canada's Hudson ...

How is climate change affecting polar regions? Climate change is amplified in the polar regions. The northern and southern reaches of the planet are warming faster than any area on Earth, with the ...

A strong, stable vortex is like a skater spinning with their arms tucked closely in, holding in an area of cold air over the Arctic. But when there’s a wobble in the rotation, winds in the vortex can ...

This prolonged fasting drains polar bears’ energy reserves, reducing their ability to reproduce and raise cubs. Without ...

Current trend in heavy snowfall and bitterly cold temperatures is directly linked to a disruption to the polar vortex caused ...

Now, researchers have discovered the bears have another unexpected Arctic adaptation: greasy fur. It’s a trait that, ...

When scientists discovered polar bear populations were dropping rapidly, they created a framework to understand what is ...

Researchers from the University of Toronto have established a direct link between the population decline in polar bears living in Western Hudson Bay and shrinking sea ice caused by climate change. The ...

the stratospheric polar vortex and mid-latitude winter weather would improve our ability to anticipate these events and their severity. Mathew Barlow is a professor of climate science, UMass Lowell.

Abnormal weather events and severe winter storms could be caused by a disrupted polar vortex. Find out here how the polar ...

The Greenland Ice Sheet is cracking open more rapidly as it responds to climate change. The warning comes in a new ...
