Antarctica’s ice loss is locked in, and extra snowfall won’t save it – that’s bad news for low‑lying coastal areas elsewhere

The Antarctic ice sheet’s future depends how a chain of events plays out. A new study finds the evidence points in one direction.

Pyrograzing turns ordinary livestock into fire prevention heroes, so why isn’t it used on public lands more often?

Targeted grazing is gaining interest as fire risk rises, particularly in hard-to-manage areas of the Western US. But it isn’t always as simple as it seems.

When a mountain falls: How ice and rock triggered Nepal’s catastrophic flood – and why climate change is raising the risks

A geologist explains how thawing permafrost and melting ice are increasing the risk of destructive floods in the Himalayas and other high mountain regions around the world.
Thermokarst ponds, or trough ponds, typically form when the ice in permafrost melts. They can also drain quickly. Anna Liljedahl

Disappearing lakes and AI are helping scientists map Arctic permafrost thaw in near‑real time

The abrupt disappearance of a lake is one clear sign that the ice below is melting, and a clue to wider permafrost changes.
Underwater data centers will accumulate sea life, like this Microsoft data center testing module, which in two years underwater attracted algae, barnacles and sea anemones. Microsoft

AI companies look to the ocean as a place to put more data centers

Moving servers into the ocean does not make underlying environmental challenges disappear. And it creates new concerns as well.

Ancient forests took 100,000 years to recover from the last global warming period similar to today – Wyoming fossils reveal what happened

Understanding what happened in these forests 56 million years ago may help humanity recognize similar thresholds before we cross them again, the lead author of a new study writes.

Chronic pain is missing from America’s heat warnings

Chronic pain can make it hard to walk, carry groceries or sleep through the night. A new study finds that extreme temperatures are linked to that kind of pain.

Cyclospora spreads through human waste – so how did it get on food?

US sewage treatment plants likely don’t get rid of all the disease-causing protozoa, and monitoring discharged wastewater for it is difficult.
