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…
Winters that brought less snow than normal shortened the snow season in Italy's mountains by as much as a month and cut summer runoff by roughly half, according to a study of 38 catchments across the…
Pull a sweater over your head, tug a cotton shirt from the dryer, and you release a small cloud of fibres too fine to see. If the garment is polyester, we have learned to worry about that cloud:…
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…
Heating a patch of desert soil for two decades made the living crust on its surface paler, drier and warmer, and the team that ran the experiment calls the result evidence of a feedback that adds to…
Researchers at the Chinese Academy of Sciences have put a long-term number on something geological carbon budgets usually leave out: how much carbon dioxide the world's dry lands pull from the air as…
Stopping all new plastic from entering the ocean by 2050 would still leave microplastic accumulating in it, a modeling study published Sept. 12 in the journal Communications Earth & Environment…
On the north side of Alaska's Brooks Range, spruce are moving into ground that used to be tundra. Observations show the treeline there advancing quickly, and the warming behind it is not in doubt.…
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…
A study published Sept. 11 in Communications Earth & Environment reports no statistically significant acceleration of drought across about 99% of the land it examined between 1981 and 2024. The…
Two East Antarctic ice shelves are releasing 70 ± 7 and 53 ± 9 billion metric tons of glacier meltwater into the ocean each year, according to a reconstruction published Sept. 11 in Nature…
Earthworms fed polystyrene microplastic for six days ended up with fewer living immune cells, and fewer still when the plastic carried an antioxidant additive, a team at the University of Bayreuth…
