A 7-year field experiment showed Antarctica’s native grass and pearlwort reworking their internal plumbing in contrasting ways as temperatures shifted.

In Northeastern North America, Alpine Zones Are Turning Green
Using satellite data, scientists have detected where once-stable alpine ecosystems are transforming into greener, shrubbier places.
A Rock Avalanche Buried an Arctic Glacier. Was Climate Change to Blame?
Degrading permafrost and earlier small quakes likely weakened a rock slope until it collapsed and buried an Arctic glacier in tons of rock.
Equatorial Pacific Warming Pattern Mitigated by Slow Ocean Adjustment
Model simulations under an abrupt 4x CO2 scenario reveal that initially enhanced gradients in sea surface temperature under global warming are then mitigated by circulation changes.
The Ambiguous Costs of Climate Change
To put a price tag on climate change, some approaches focus on whether it made an event more likely, whereas others focus on whether it made an event more severe and damaging. A new study examines the validity of both approaches.
Clouds over the Highest Mountains Dance a Little Differently
Clouds over the Tibetan Plateau and the Andes are growing colder and higher than other clouds in response to climate change. That could affect local hydrology and radiation.
Measuring Deep-Ocean Oxygen with Microscopic Magnetic Fossils
A global comparison of microbial magnetic minerals unlocks a new tool for glimpsing the future of oxygen in Earth’s changing oceans.
A Hydrological Paradox on the Silk Road
How did trade prosper in Central Asia during a period of droughts and little rain?
2026 State of the Climate Report Shows a Planet Reaching Its Limits
The seventh edition of an annual report analyzing Earth’s “planetary vital signs” indicates that Earth systems are rapidly destabilizing, some at an accelerating rate.
The report, published today in BioScience, analyzed 16 of these signs, including greenhouse gas emissions levels, ocean heat content and acidity, the mass of major ice sheets, the number of hot days, Earth’s surface temperature, and more.
Patchier Permafrost Is Linked to More Intense Hillslope Erosion
Arctic landscapes with spots of disconnected permafrost erode faster than those with continuous permafrost, a new study finds.
