The monthly sea surface temperature in the Pacific's Niño 3.4 region, the stretch of ocean used to monitor El Niño, reached an all-time high of 29.70 °C in September 2026, the Copernicus Climate…
In January the sun does not set over Dronning Maud Land, and the flat white top of the Nivlisen Ice Shelf turns blue in lines. The lines are rivers. They begin as pools inland, cut down into the ice,…

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…
Atmospheric circulation accounts for about 60% of the rise in summer dryness over eastern Siberia between 2004 and 2024, according to a study published Oct. 10, 2026, in Communications Earth &…
The Delta Flume at Deltares in Delft is a concrete canal 300 meters long, and in February and March 2024 a Dutch team filled it with a salt marsh: blocks of turf cut from the Frisian coast, laid out…

An assessment of 1,029 cities published Oct. 11, 2026, in Communications Earth & Environment reports that urban heat risk rose worldwide between 2000 and 2019, with the upward trend in the Global…
Climate model experiments published Oct. 10, 2026, switched carbon dioxide emissions off abruptly, and global average temperature stabilized. The modeled Arctic did not. It went one of two opposite…
Everyone in climate-impact modeling has had the same instinct for years: a finer grid must give a better answer. Computing power got cheaper, climate data got sharper, and the boxes that data is…
