Marine heatwaves raised net carbon dioxide uptake in the world's continental shelf seas by 11.0 ± 1.6% between 1985 and 2020, a team led by Zhentao Hu of Helmholtz-Zentrum Hereon in Geesthacht,…

A modeling study published Sept. 1 in Communications Earth & Environment calculates that an additional sustained 10% cut in methane emissions held to 2050 (about 35 MtCH₄ per year, or megatons of…

Trace the water in a Denver or Sacramento tap back far enough and the pipe becomes a mountainside: a patch of conifer forest holding snow through the spring and letting it go into a creek. Most of…

Researchers have mapped where seaweed carbon is buried along the world's coasts and report that the most favorable burial grounds occupy less than 1% of global coastlines. The assessment, from a…

Under Net Zero, Dam Reservoirs Would Become the Energy Sector's Top Emitter by 2050 Greenhouse gases from hydropower reservoirs would account for 87% of energy-sector emissions by 2050 if the rest of…

A forest does not only take carbon in. On a warm afternoon it hands some straight back, as a thin chemical breath of isoprene, monoterpenes and heavier molecules, the family of compounds that gives a…

For two years, a sealed culture of marine microbes fed itself in a Chinese laboratory: a cyanobacterium and the bacteria that live alongside it, recycling their own nutrients, with nothing added and…

Wildfire strips the loosest part of soil carbon far faster than the carbon locked onto minerals, and the loss keeps deepening for about two decades after a fire, according to a synthesis of 210…

A study published on Aug. 29, 2026, in Communications Earth & Environment estimates how much carbon dioxide Mexico's groundwater use puts into the atmosphere, using satellite measurements of the…

Researchers at Harvard's Wyss Institute have engineered a marine bacterium to make the mineral olivine dissolve faster, and measured carbon dioxide being pulled out of the air in a pilot-scale tank…

A concrete frame is a debt in climate accounting. The cement in it released carbon dioxide on the way to becoming cement, and nothing the finished wall does afterward pays that back. A timber frame…

A synthesis of natural volcanic watersheds published Aug. 26, 2026, in Nature finds that the dissolved chemistry carrying a carbon-removal benefit downstream is partly lost between the soil and the…
