Europe's Melting Glaciers: Rhone

OBERGOMS, SWITZERLAND - AUGUST 23: In this aerial view the Rhone glacier water flows from a waterfall formed by the glacier's meltwater on August 23, 2019 near Obergoms, Switzerland. The glacier once covered both areas as well as a valley far below in thick ice. The Rhone glacier is the source of the Rhone river. Since the 1850s the glacier has lost approximately 1,300 meters in length. While the retreat of glaciers across Europe is part of a natural process that began with the end of the Little Ice Age in the mid-19th century, the acceleration of the melting since the 1960s is a phenomenon many scientists attribute to human activity that is further warming Earth's climate.
