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 ...

A third of the Arctic is now emitting climate-changing greenhouse gasses after thousands of years of storing them, according ...

A lobe of the polar vortex will arrive in the United States this weekend, bringing the lowest temperatures in years and snow and ice to the East and Deep South.

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

[KOREA POLAR RESEARCH INSTITUTE] Scientists in the Arctic and Antarctica say humans are triggering climate change, warning that shrinking glaciers and icecaps in relatively unexplored polar ...

Today, due to the rapidly melting ice sheets of the Arctic Ocean, Greenland and Antarctica, polar exploration can reveal the immediacy of the world's climate change crisis. Without a significant ...

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.

The images below show how the influence of climate change from as far away as the mid-latitudes can trigger an outbreak of arctic air over the United States weeks to months later. Unable to view our ...

Research is revealing how climate change is driving the Arctic-boreal zone's shift from a carbon sink to a carbon source.

Anytime we get an Arctic air blast down this far south, this is an artifact of the polar vortex rearing its ugly head,” said ...

University of Toronto Scarborough researchers have directly linked population decline in polar bears living in Western Hudson Bay to shrinking sea ice caused by climate change.
