EARTH SCIENCE ARCHIVE
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.
Biosignatures Extend Robustly into the Top Kilometer of Sedimentary Basins
Through the top kilometer of sedimentary basins, biosignatures track microbial cells, permeability, and water inputs. Below that, permeability limits microbial presence despite temperatures conducive to life.
Auroral Structure Could Be Caused by Bouncing Electrons
High-resolution optical observations of aurorae show fluctuations and structuring that could be explained by interactions between electrons and a plasma phenomenon called Alfvén waves.
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…
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.
Life in the Skies Links Ecosystems Near and Far. It Deserves More Attention.
Our understanding of Earth’s biology and its responses to environmental change is limited by an incomplete picture of the planet’s dynamic aerobiome.
A Snow Machine Traverse Connects Arctic Coastal Communities
A scientific expedition connected community perspectives, landscape conditions, and coastal hazards across nearly 3,200 kilometers of Alaska coastline.
