They are incredible images. Scientists from ETH Zurich and the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) reconstructed for the first time the melting of glaciers throughout the 20th century across all of Switzerland. The researchers used historical imagery to do this. ETH Zurich stated in a press release that they came to the conclusion that the volume of glaciers fell by half between 1931 and 2016.

In an article just published in the professional journal The Cryosphere, a team of researchers from ETH Zurich and the WSL reconstructed the topography of all Swiss glaciers as they were in the year 1931. Based on these reconstructions and comparisons with data from the 2000s, the researchers came to the conclusion that the volume of these glaciers has dropped by half between the years 1931 and 2016.
