Mont Blanc height drops over 1 meter in a year, Alpine climate shifts

Mont Blanc's official height has been measured at 4,807.47 meters, down more than a meter from the previous year, reflecting ongoing changes in Alpine climate and ice cover. The measurement is part of a biennial survey; the decline is consistent with recent trends of reduced snow and ice accumulation. This matters as a tangible indicator of climate-driven geophysical change in the European Alps.
