Some of the most productive apple regions in America are facing big challenges from a changing climate, according to a Washington State University study.

Huge swaths of North America are facing subfreezing temperatures this week as cold Arctic air pushes southward. 

2024 was another year of record-breaking temperatures, driving the global water cycle to new climate extremes and contributing to ferocious floods and crippling droughts, a new report led by The Australian National University (ANU) shows. 

Marine heatwaves are becoming more frequent and intense. The Arctic Ocean also suffers from this development: The absence of sea ice will lead to more extreme fluctuations in ocean temperatures, with abrupt temperature changes occurring at unprecedented rates.

In the Arctic, the old, multiyear ice is increasingly melting, dramatically reducing the frequency and size of pressure ridges.

A new study investigating ancient methane trapped in Antarctic ice suggests that global increases in wildfire activity likely occurred during periods of abrupt climate change throughout the last Ice Age.

More than half a billion years ago, a meteorite struck Earth near the Antarctic Circle, leaving a divot several kilometers in diameter.

Last year saw warming reach startling new highs, with record heat fueling extreme weather around the world.

Academics from Northumbria University are part of an international research team which has used data from satellites to track changes in the thickness of the Greenland Ice Sheet.

When icebergs break from an ice shelf or large glacier front, they ride the ocean’s currents, spin in its eddies, shift with the tides, and are blown by the wind.
