Researchers at the Karlsruhe Institute of Technology report that a standard machine-learning model for turning rainfall into river flow underestimated 97% of the highest flows in a Swiss test set,…
Adding a machine learning correction step on top of existing weather models improved their forecasts two to six weeks ahead, a team led from Microsoft Research reported Oct. 14, 2026, in Nature. The…
Flood peaks arrived earlier at 52.2% of the river sites a global satellite survey could measure over 2008 to 2025, and at 27 of the 50 largest river basin outlets, researchers report in…
Researchers at the UK Centre for Ecology and Hydrology and the Met Office Hadley Centre have published an evaluation of the river flow forecasting scheme that has driven Great Britain's monthly water…
The Antarctic ozone hole in 2025 was one of the least severe in more than two decades, the World Meteorological Organization reported in its annual ozone bulletin, published Sept. 16. It was the…
A seven-day temperature forecast in a high-income country is on average about as accurate as a one-day forecast in a low-income country, two researchers at Columbia University report in a global…
Four severe droughts between 1998 and 2022 cut annual river flow across the Upper Colorado River Basin by about 15% and left the water warmer and saltier at the same time, a team at Lawrence Berkeley…
The busiest day of the Atlantic hurricane season, by the long-run average, is September 10. That day came and went with no hurricane anywhere in the basin, and so did the day after it. When September…
About 70% of the year-to-year difference in how severe northern India's winter air pollution becomes is governed by storms that arrive from the Mediterranean, a team led by Yuanyu Xie of Princeton…
Fires that follow a flash drought, a rapid collapse of root-zone soil moisture over days to weeks, spread roughly 1.3 to 1.8 times faster in their opening hours than fires not linked to flash…
Forecasters have a name for the moment a tropical cyclone turns dangerous fast: rapid intensification, an increase of about 35 mph in maximum winds within 24 hours. When it happens far out over open…
A heatwave rarely leaves an obvious body count. There is no single moment, no wreckage to photograph. Most of the people it kills die at home or in hospital wards over a stretch of days, their deaths…
