15 million people around the world live under threat of glacial floods: study
, but 1 million people live within just 6 miles of potentially unstable glacial-fed lakes, the study calculated.
Scientists say so far it doesn’t seem like climate change has made those floods more frequent, but as glaciers shrink with warming, the amount of water in the lakes grows, making them more dangerous in those rare situations when dams burst. “In a warming world we certainly expect more and larger glacial lakes,” Shugar said in an email. “But the threat that these lakes might pose critically depends on where people are living and what their vulnerabilities might be.”
After the deadly Andes flood in the 1940s that region “was sort of a leader” in working on glacial flood outburst threats, but in the last decade or so, High Mountain Asia has taken over because of the high population, said University of Dayton geology professor Umesh Haritashya, who wasn’t part of the studies.
