Spreading crushed basalt on China's croplands for a single year could remove 0.44 to 0.79 billion metric tons of carbon dioxide by 2100, at a net cost of 127 to 226 U.S. dollars for every metric ton…

Europe's continental shelf already breathes in two ways, and the dividing line sits near 60 degrees north. South of it, temperature sets the rhythm: cold winter water dissolves carbon dioxide easily…

Over two years, 9.5% to 11% of the carbon dioxide that crushed basalt could in theory remove from the air left a Vermont watershed, dissolved in its stream, a team led by Yale University researchers…

A 39-day experiment in the German North Sea has measured how much alkaline material seawater can take before a spring plankton bloom runs late. Juliane Tammen of GEOMAR Helmholtz Centre for Ocean…

The hardest hours for a grid that runs on weather are not the still ones, and not the overcast ones. They are the hours that are both at once, and the worst of those arrive sharply rather than…

A picosecond is a trillionth of a second. Light itself crosses only about a third of a millimeter in one. Inside the carbon-based solids chemists want to use to make hydrogen from sunlight, that is…

Suppose the world one day takes more carbon dioxide out of the air than it puts in. Emissions fall to zero, then go past it. The air thins, the planet stops warming and slowly starts to cool. What do…

Closing a stretch of seabed off Oregon to trawlers to make room for floating wind farms would change the groundfish catch very little, and would not hand the fishery much of a bonus either, according…

China's carbon dioxide emissions fell by about 1% year on year in the second quarter of 2026, according to a quarterly analysis by Lauri Myllyvirta, lead analyst at the Centre for Research on Energy…

Baseline solar electricity costs range from $0.100 to $0.409 per kilowatt-hour across 184 districts of the West African Power Pool, a University of Groningen-led team reports in a modeling study…

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 tractor spreads crushed basalt across a field, and a number appears in a ledger: so much carbon dioxide, removed. The chemistry behind that number is textbook. Rain and soil acid attack the rock,…
