“From the rapidly melting Greenland ice sheet to increasing instability of West Antarctica, the world’s glaciers have become the dramatic face of climate change. But while ice loss at the poles often garners the most attention (thanks to its hefty potential contributions to global sea-level rise), other smaller glaciers all over the world are also steadily shrinking — and scientists say they constitute some of the clearest signals of climate change on the planet.
A new study, published Monday in the journal Nature Geoscience, uses a new statistical method to analyze the retreat of mountain glaciers all over the world, from Russia to South America. It concludes that their shrinking represents “categorical evidence of climate change.”
“It’s the first time that’s somebody’s done a formal climate change attribution study of mountain glacier length changes,” said Andrew Mackintosh, a glaciology expert at the Victoria University of Wellington in New Zealand who was not involved with the new study.”
