Research using NASA satellite images has revealed a concerning retreat of snow cover atop Mount Everest, indicating a lack of snow accumulation during the winter season of 2024-2025. This trend, observed through a 'rising snow line', suggests a warming climate and warmer, drier conditions prevailing in recent winters. Glaciologist Mauri Pelto attributes the snow cover loss to sublimation, where ice directly evaporates, contributing to the retreat of glaciers even above 6,000 meters on Mount Everest.
