Alaskas glaciers have a startling response to rising temperatures

Alaskas glaciers are proving to be highly sensitive to warming temperatures. Using radar satellites to monitor more than 3,000 glaciers, researchers found that every 1C (1.8F) increase in average summer temperature extends glacier melting by about three weeks. The study also revealed that intense heat waves can strip away up to 28% more protective snow cover, exposing ice much earlier than normal and accelerating ice loss.
