Glacier retreat refers to the process where glaciers lose mass and shrink in size due to melting and sublimation. This phenomenon is primarily driven by rising global temperatures, which can be linked to climate change. As temperatures increase, the rate of ice melting often surpasses the rate of snowfall that replenishes the glacier. The retreat of glaciers has significant environmental impacts, including rising sea levels and changes in local ecosystems. Many famous glaciers, such as the Himalayan glaciers and Greenland ice sheet, are experiencing rapid retreat, which raises concerns about water supply for millions of people and the overall health of our planet.
