Marine Heatwaves Reshape Precipitation Patterns

by Yun Qian 6 November 20256 November 2025

Most marine heatwaves experience reduced precipitation throughout their lifetime, but warmer events in the early stage can trigger increased precipitation after reaching peak intensity, causing faster decay.

Rising Temperature and Decreasing Snow Cover Increase Soil Breakdown

by Alberto Montanari 30 October 202530 October 2025

With climate change and rising temperatures, soil freeze-thaw – which is in turn causing soil breakdown – may counterintuitively increase in the hillslopes where snow cover is decreasing.
