Mountain glaciers: on thinning ice

Mountain glaciers are key indicators of climate change. Glacier changes are the most visible evidence of global climate change we have. They affect the appearance of the landscape in high mountains and impact regional water supplies, local hazard conditions and global sea levels. Glaciers may be found in, and compared across, all latitudes – from the equator to the poles. Due to their sensitivity to climatic changes, glaciers are key indicators for use in global climate observation system
