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.

How Bubbles Reshape Air-Sea Gas Exchange
Bubbles produced by breaking waves provide an important but often overlooked pathway for exchanging carbon dioxide, oxygen, and other gases between the ocean and atmosphere.

Rising CO2 Alters Upper Atmosphere Response to Stratosphere Sudden Warming
A whole-atmosphere model simulation shows that rising CO2 changes how the upper atmosphere and ionosphere respond to a sudden stratospheric warming (SSW), with implications for future space weather.

Melting Glaciers Make the Coastal Ocean More Sensitive
Fresh water from retreating ice does more than raise sea levels. It affects how the ocean responds to acidification and other environmental changes.

Volcanism Could Lead to Less, Not More, Atmospheric CO₂
The atmospheric concentration of carbon dioxide temporarily fell by 50% immediately preceding a period of intense volcanism, likely because of increased weathering, new results reveal.

Rates of Mineral Dissolution from the Flask to Enhanced Weathering
Assessing the rate that weathering could draw carbon dioxide out of the atmosphere requires understanding why lab- and field-based rate measurements differ by orders of magnitude.
