Water stored beneath Glacier de Bonne Pierre may have contributed to the severe June 2024 flood at La Bérarde in the French Alps, a study finds. The researchers estimate that subglacial barriers could theoretically have held water on the order of 10^5 cubic metres, but observations cannot confirm that such pockets existed or drained.
A climate-model study finds that permafrost can continue thawing and releasing carbon for decades after warming begins to decline. The delay in recovery was larger when peak global warming exceeded 2 °C, although the results come from idealized experiments with one Earth system model.
Rainfall-triggered landslides may become more common in part of southern Italy even as climate projections show generally drier soils. Modeling suggests that changes in rainfall intensity and the moisture left by earlier rain could outweigh the drying trend.
