Aug 26, 2019 According to initial findings from the Swiss Glacier Monitoring Network (GLAMOS), Swiss glaciers experienced unusually high melt rates during the last heat wave, which occurred in late July, and an earlier heat wave that struck the continent in late June. The melting glaciers have brought more runoff. Where and by how much have temperatures most drastically changed? Melting glaciers could provide new opportunities for clean energy production in Switzerland.

It's based on an early analysis of on-site measurements at certain sites, combined with a model that scales up the measurements to estimate total ice losses throughout the country. The sweltering heat wave that roasted much of Europe last month has since moved north, where it's wreaking havoc on the Greenland ice sheet. Alpine glaciers form on the crests and slopes of mountains.A glacier that fills a valley is called a valley glacier, or alternatively an alpine glacier or mountain glacier.
