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…

Forecasters at the Darwin Volcanic Ash Advisory Centre used laser measurements from Europe's EarthCARE satellite to verify how high the ash plume from Anak Krakatau was reaching, the European Space…
The authors' sketch of how newly formed particles feed droplet nuclei in each regime. Red arrows mark the estimated direction of future change under an intermediate emissions scenario. — Fig. 4 from…
Picture a familiar landscape (a stretch of coast, a patch of forest, a wetland you have known for years), and then imagine it slowly filling with the wrong things. Species that were never there…
An atmospheric river is a corridor of water vapor sliding through the air toward a coast, and it behaves less like a storm than like plumbing. The water is going somewhere. What decides where it…
In dry country a river is often a line on a map and a bed of dry stones. Then a storm arrives, the stones are wet for an afternoon, and somewhere downstream a gauge registers a pulse of water. How…
