| Summary: | <!--!introduction!--> During the last three decades, the glacierised areas of the Himalaya have shown cooling and drying conditions, caused by higher ablation rates of glaciers in response to global warming ( Salerno et al., 2023. Glacier feedback on Himalayan climate under global warming - this conference ). While this local negative feedback does not preserve glaciers from melting, it could protect the periglacial environment, extending between the mean elevation of glaciers (~5400 m a.s.l.) and downslope areas (even below 4500 m a.s.l.). Across this elevation band, areas of permafrost are likely to exist. Here, we analyse the world’s longest time-series of soil temperature data (from 2003 to 2022) measured at a high-elevation station located close to the glacier masses (Pyramid, Mt Everest, 5035 m a.s.l.), together with climate observations, reanalysis (ERA5-Land), and remote sensing data (MODIS). We show that a diurnal cooling of soil temperature at 5-cm depth occurred in the last twenty years ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
