Research has found that rising temperatures in the Arctic are weakening weather systems that normally trap the cold around the poles, making winter weather more chaotic.

Ranked dead last, or perhaps not mentioned at all, would probably be the only state that sits partly within the Arctic Circle: Alaska. But 2025 is off to an interesting start as far as the weather is concerned.

A strong polar vortex in the stratosphere has brought subzero temperatures to the Midwest, Mid-Atlantic and deep into the South.

The United States is currently experiencing an intense cold front linked to the so-called Arctic “polar vortex”.  The icy air that has particularly affected the central and eastern United States is now descending as far as the Gulf Coast.

With last week's freeze being the second time temperatures dipped below freezing this winter, many are wondering if this active winter pattern is setting the stage for an even colder February.

A dangerous and potentially life-threatening stretch of cold weather has much of the U.S. on alert as a lobe of the polar vortex invades the nation ... the ceremony will be held inside the United States Capitol Rotunda. These temperatures are undoubtedly ...

As the Arctic rapidly warms, the temperature difference between the polar region and lower latitudes decreases, which weakens the jet stream.

With little snow to bother them, thousands of sandhill cranes stopped their southern migration in Nebraska. "The past few years have been kind of crazy," says Bethany Ostrom, lead biologist
