The Arctic is warming at an accelerating pace.

The effects of a meager mountain snowpack across the Upper Colorado Basin in winter 2025-2026 had made their way downstream to Lake Powell by summer. 

Documenting the seasonal fate of these tiny marine organisms is a step toward understanding how ecosystems in the world's fastest-warming region may change as ice recedes.

A new study found more than half of the city’s bike-share trips replace car trips, with each bike reducing annual CO2 emissions by up 120 kilograms (kg) per year.

If someone leaves the faucet running in your bathroom and the house floods, it’s easy to assign responsibility for the damage.

Study finds increased precipitation outpaces water loss from warmer temperatures.

For decades, Arctic sea ice has been melting earlier in spring and freezing later in fall, extending the melt season and contributing to widespread ice loss.

Researchers have shown how dramatic sea level rise, over a 5,000 year period, profoundly changed the coasts of northern Italy, Slovenia and northern Croatia.

Forests and woodlands cover millions of hectares across Australia, from tropical rainforests and temperate eucalypt forests to the vast woodlands and shrublands of the arid interior.

The same amount of rain falling on the same landscape at different times can send very different amounts of water into its rivers, according to a new study in Nature Water.
