An extended test on Alaska’s North Slope extracted methane released from a gas-hydrate reservoir for 151 days. The produced gas was mostly secondary microbial methane, and the reservoir yielded an unexpectedly high amount of gas compared with water.
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.
