Climate change causes glaciers to melt. We have often been warned about this phenomenon. Now a new study shows that Swiss glaciers shrunk by half their volumes since the year 1931.
This inference was drawn following the first reconstruction of the country’s ice loss in the 20th century. The rapid glacier melt in the Alps and elsewhere has been closely monitored since the early 2000s but there has been little insight.
Recently, some Swiss researchers reconstructed the Topography of all Swiss glaciers. This reconstruction made it possible to show how they have evolved in a statement. The researcher elaborated that it is based on this reconstruction and comparison with data from the 2000s that they concluded that the glacier volume halved between 1931 and 2016. They start using material from the terror image archive and analyzed around 21,700 photographs taken between 1916 and 1947.
For the reconstruction, the researchers used a method known as Stereo photogrammetry. This is essentially a technique used to determine the nature, shape, and position of any object on the basis of image pairs. Therefore, if researchers know the surface Topography of a glacier at two different points they can calculate the difference in volume.
Researchers stressed that glaciers did not continuously fade over the past century. They suggested that there was sporadic Mars Glacier growth in the 1920s and 1980s. The Swiss Glacier monitoring network, Glamos indicated that Glacier melt was more rapid after 2016. One of the researchers warned that evidence was clear Glacier Retreat is accelerating.
