A reconstruction of tropical Indian and Pacific Ocean climate back to the early 1600s finds the two basins moved largely in step until a run of volcanic eruptions in the early 19th century disrupted…
Coatings that build up on soot particles in the air raise black carbon's warming effect from 0.20 watts per square meter, plus or minus 0.25, to 0.30 watts per square meter, plus or minus 0.42,…
A study published Aug. 25 in Communications Earth & Environment attributes 40% to 64% of the climate-driven decline in western US water supply to emissions from 122 fossil fuel and cement producers,…
Over the Arabian Peninsula, the haze that dims the sky is often not smog in the familiar sense. It is dust, lifted off deserts and carried on the wind, and it is one of the harsher air-quality…
El Nino is famously a creature of the calendar. It flares roughly every two to seven years, tips global weather off its usual paths for a season or two, and fades. Ask what it does to the world's…
Take every stretch of open ocean outside the polar seas, average the surface temperature across all of it, and the number you get has a season of its own. It is not the season most people live in. It…
The physics of climate change runs on decades and centuries. Politics runs on the last hot summer. A new modeling study asks what happens when you wire the two together and let the short clock start…
A modeling study projects that the area burning in Europe each year would rise by about 39% under low emissions and by nearly 192% under high emissions late this century, driven by intensified fire…
Sea surface temperatures in three of four European sea regions this summer reached a level that "would have been virtually impossible in a pre-industrial climate," World Weather Attribution said in a…
Picture the planet at the instant the last tonne of carbon dioxide is neutralized. The furnace has been switched off. The obvious question is whether the room now stays warm, keeps heating, or begins…
There is a frustrating gap in what climate science can and cannot tell you. Ask whether Europe's summers will keep warming over the coming decades, and the models answer with confidence. Ask what the…
A rainforest is, among other things, a machine for moving water. Roots pull moisture from deep in the soil, leaves breathe it into the air, and the vapor drifts downwind to fall again as rain…
