15 million people around the world live under threat of glacial floods: study

As glaciers melt and pour massive amounts of water into nearby lakes, 15 million people across the globe live under the threat of a sudden and deadly outburst flood, a new study finds. More than half of those living in the shadow of the disaster called glacial lake outburst floods are in just four countries: India, Pakistan, Peru and China, according to a study in Tuesday’s Nature Communications. A second study, awaiting publication in a peer-reviewed journal, catalogs more than 150 glacial flood outbursts in history and recent times.

Earth's frozen 'water towers' threatened by warming, population growth, report says

Earth's frozen 'water towers' threatened by warming, population growth, report says

Water frozen at the tops of mountains that helps sustain up to a quarter of the human population is under threat from climate change, population growth and lack of proper management, according to a new international study. The systems store and transport water through glaciers, snow packs, lakes and streams. They supply water to 1.9 billion people on Earth. A group of 32 international scientists — including one Canadian — published a paper in the journal Nature on Monday to highlight the importance and vulnerabilities of what they call Earth's 78 water towers.
