Already shrunk by half, Swiss glaciers melting faster: Study

GENEVA: A new study has found that Switzerland's 1,400 glaciers lost half their total volume since the early 1930s, and researchers say the ice retreat is accelerating at a time of growing concerns about climate change.

The researchers found that ice volumes had shrunk by half over the subsequent 85 years - until 2016. Since then, the glaciers have lost an additional 12 per cent, over just six years. The research involved using decades-old techniques to allow for comparisons of the shape and position of images of terrain, and the use of cameras and instruments to measure angles of land areas. The teams compared surface topography of glaciers at different moments, allowing for calculations about the evolution in ice volumes.
