When comparable methods and datasets are used, climate attribution results hold up across different choices of how an extreme-weather event is defined. A new synthesis of published studies finds that…
A new study reports that the amount of dust suspended in Earth's atmosphere fell by roughly 10% between 2003 and 2023, and that the decline has made a modest contribution to the warming observed over…
Net zero is usually drawn as a finish line. Emissions come down, the line touches zero, and the graph of global temperature flattens out. What that picture leaves out is that the world never warmed…
Human-caused climate change had added about 1.5 °C to July and August temperatures at the Himalayan slope that gave way on Aug. 26, 2026, the World Weather Attribution network reported on Sept. 17.…
A study published Sept. 16 in Nature Climate Change puts the cost of heat that slows workers down at roughly $41 for every ton of carbon dioxide emitted in 2025, a loss the authors say has been…
The World Meteorological Organization reported Sept. 17 that 2025 was one of the driest years for the world's rivers in more than three decades, in the agency's annual assessment of the global water…
Amazon trees that have had half their rain taken away for more than two decades came through the record 2023 El Niño drought in better shape than untreated trees nearby, researchers report in a study…
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…
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.…
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…
Particles floating in the air over the northwestern Amazon are efficient at starting the ice in cirrus, the thin clouds that form high in the atmosphere. The larger particles do it better as the air…
The hottest days of the Amazon dry season are warming more than twice as fast as the region's average temperature, a research team led by Jos Barlow of Lancaster University reported on Sept. 10,…
