  1. Up to 15 million people face risk of catastrophic flooding from glacial lakes which could burst their natural dams at any moment, a new study finds. The study led by Newcastle University is the first global attempt to map potential hotspots for such floods. As the climate warms, glaciers retreat and meltwater collects, forming lakes.

    These “glacial lake outburst floods,” as scientists call them, can be catastrophic — capable of crushing houses, flattening hydroelectric projects and destroying other infrastructure in their paths. They’ve been known to cause hundreds of deaths when they occur. Scientists worry that these events may be poised to increase.

    A new study finds that as glaciers melt and pour massive amounts of water into nearby lakes, some 15 million people across the globe are living in the danger zone of a sudden and deadly outburst flood.

      A second study, awaiting publication in a peer-reviewed journal, catalogs more than 150 glacial flood outbursts in history and recent times. It’s a threat Americans and Europeans rarely think about, but 1 million people live within just 6 miles (10 kilometers) of potentially unstable glacial-fed lakes, the study calculated.
      The recent accelerated expansion of glacial lakes and increased glacial lake outburst flood activities in the Tibetan Plateau and its surroundings indicate that numerous communities and infrastructure downstream are at a higher flood risk than previously understood.
      Nature Communications 14, Article number: 487 ( 2023 ) Cite this article Glacial lake outburst floods (GLOFs) represent a major hazard and can result in significant loss of life. Globally, since 1990, the number and size of glacial lakes has grown rapidly along with downstream population, while socio-economic vulnerability has decreased.
      At the same time, more people—along with their buildings and farms—have populated vulnerable areas downstream of glacial lakes. As a result, millions now live within 30 miles of a glacial lake. The communities with the highest risk are those located in the high mountains of Asia, such as Nepal, Pakistan and Kazakhstan.
