Arctic sea ice had its weakest winter buildup since record-keeping began 47 years ago.

Global temperatures in 2024 soared to yet another record level, but this time it was such a big jump that Earth temporarily passed a major symbolic climate threshold.

Greenland plays an outsized role in the daily weather experienced by billions of people and in the climate changes taking shape all over the planet.

Frigid air that normally stays trapped in the Arctic has escaped, plunging deep into the United States for an extended visit that is expected to provoke teeth-chattering but not be record-shattering.

A major winter storm began Saturday in the central U.S. and is forecast to move east over the next several days.

A warming earth has brought milder winters, but emerging science suggests that extreme cold spells in Texas could also result from climate change messing with complex weather processes.

A new study finds that the warming of the Arctic due to climate change has increased the number of polar vortex outbreaks, when frigid air from the far north bathes the central and eastern United States in killer cold.
