In many areas, glaciers provide communities and ecosystems with a reliable source of streamflow and drinking water. Glaciers are an important climate change indicator because physical changes in glaciers—whether they are growing or shrinking, advancing or receding—provide visible evidence of changes in temperature and precipitation. If glaciers lose more ice than they can accumulate through new snowfall, they ultimately add more water to the oceans, leading to a rise in sea level. On average, glaciers worldwide have been losing mass since at least the 1970s, which in turn has contributed to observed changes in sea levels. The rate at which glaciers are losing mass appears to have accelerated over roughly the last decade. 🧊Learn more about glaciers as climate change indicators: https://lnkd.in/ebrc2bFd
I went to Alaska last month and it’s was beautiful but it is so saddening how much we have lost.

3wSo which communities use silt-laden glacial runoff as drinking water? As an Alaskan, I find this assertion problematic and disturbing.
