a natural phenomenon that develops in the polar regions during winter, got much attention. Although the term polar vortex may seem relatively new, it isn’t. Disruptions of the vortex were first ...

The polar vortex, a swirling mass of cold air located over the polar regions, is responsible for the cold. It's bringing extreme cold as far as the Deep South. Overnight lows will be well below ...

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 ...

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

Researchers have directly linked population decline in polar bears living in Western Hudson Bay to shrinking sea ice caused by climate change.
