Model simulations under an abrupt 4x CO2 scenario reveal that initially enhanced gradients in sea surface temperature under ...

High-resolution optical observations of aurorae show fluctuations and structuring that could be explained by interactions ...

Through the top kilometer of sedimentary basins, biosignatures track microbial cells, permeability, and water inputs. Below that, permeability limits microbial presence despite temperatures conducive ...

A new study suggests cross-hemispheric overturning circulation could continue for centuries, even as North Atlantic Deep ...

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 ...

Arctic landscapes with spots of disconnected permafrost erode faster than those with continuous permafrost, a new study finds ...

Borehole distributed acoustic sensing (DAS) offers a more precise way to measure small earthquakes, if appropriate care is ...

A researcher uses housing and poverty data to identify locations where children are more likely to be exposed to lead.

Changes in river chemistry in the northwestern North American Arctic reflect increased acid rock drainage associated with permafrost thaw, an unexpected consequence of Arctic warming.

A global comparison of microbial magnetic minerals unlocks a new tool for glimpsing the future of oxygen in Earth’s changing oceans.

Satellite carbon dioxide observations detect more carbon-cycle extremes than ground stations but still miss many events and underestimate their magnitude.
