Climate scientists hold global warming responsible for the retreating Rhône Glacier, source of the River Rhône, now melting in summer below the Furka Pass in Valais canton, Switzerland, at a height of about 2,208 m (7,244 ft). In 1850, a tongue of ice extended well down the side of the mountain before melting in the valley below. The glacier flows for 7.65 km (4.75 mi) from high Urner Alps snow fields at about 30 to 40 m (100 to 130 ft) per year. The torrent flowing from the melt water lake begins the river’s 813 km (505 mi) journey through southern France to the Mediterranean.
