Despite a warming climate, bone-chilling winter cold can grip parts of the U.S. In a study appearing in Science Advances, researchers found that two specific patterns in the polar vortex, a swirling ...

Every year, weather enthusiasts eagerly watch and wait for signs that the polar vortex, a mass of cold air spinning around the Arctic, might meander south, sending cold and snow into the lower ...

There is a sudden warming about to happen high up in the atmosphere. This warming usually affects the Polar Vortex.

Sometimes humorously, sometimes dramatically, these Nature Photography prize winning images are a stunning visual tribute to the beauty and fragility of our planet.

These polar vortex stretches are happening more frequently as the world — and especially the Arctic — warms, a 2021 paper published in the journal Science, also co-authored by Cohen, demonstrated.
