Glaciers in the Alps have shrunk 39% in the last two decades, satellite data reveals

British startup Earthwave and a group of European scientists have used satellite data to map out glacial melt across the globe — and the results are alarming. The team discovered that the European Alps’ glaciers have shrunk the most of all — 39% in just over two decades, compared to a global average of 5%. Earthwave co-founder Livia Jakob said the project was invaluable to our understanding of glacier ice loss.  “We developed an algorithm to combine all the different datasets into one common estimate of glacier mass balance, giving us a new and improved picture of glacier behaviour in…
