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

To understand what Americans are experiencing with this winter blast, we need to look more than 20 miles above the surface of ...

So last year, Chalif led a study that used machine learning to analyze climate records stretching back to 1901. The team ...

Tens of millions of people are in the path of a major winter storm. Federal cuts threaten efforts to understand the causes of such weather.

Climate change does not just mean warmer weather everywhere. This video explains how rapid Arctic warming can weaken the polar vortex, distort the jet stream, and allow frigid air to plunge south into ...

A warmer atmosphere has the potential to hold more moisture, which can contribute to heavier precipitation in any season, scientists say.

Dartmouth researchers used machine learning and long-term climate records to construct a timeline of jet-stream variability since 1901. Nearly all prior studies of the jet stream focus on the period ...

A blast of winter cold doesn’t contradict climate change — it often reflects how a warming planet is making weather more ...

The frigid temperatures, massive snow and deadly ice storm taking shape east of the Rockies might seem to conflict with life on a rapidly warming planet. But all of these things still happen, even ...
