Reaction: Research estimates 15 million people at risk from glacial lake outburst floods
As rising temperatures melt glaciers, meltwater can accumulate and form lakes nearby. These bodies of water represent a natural hazard because of the floods they cause if they overflow. Researchers have estimated that 15 million people are at risk from these floods, and more than half of them live in just four countries: India, Pakistan, Peru and China. The research is published in Nature Communications.
