Streamflow Drought Intensification in the European Alps

by Valeriy Ivanov 1 February 202331 January 2023

A five-decade analysis of drought generation processes in the Alps shows their changing seasonality in high-elevation basins with increasingly frequent droughts caused by a lack of snowmelt water.

Clumped 18O –18O in Ice Reveals Past Ozone and Wildfire

by Sarah Feakins 9 December 20227 December 2022

Reactive gases like ozone are hard to preserve, but clumped isotopes and models provide clues to past ozone and suggest a global increase in wildfire at megafaunal extinction.
