Scientists say glacier retreat is starting to reduce the amount of meltwater available during extreme heat and drought.
Almost 1,400 Swiss glaciers remain, the most among European nations, but over 1,000 small glaciers have already melted.
More than 275,000 glaciers cover 700,000 square kilometers of the planet. Glaciers and ice sheets store 70% of all freshwater.
Glaciers lost more than 9,000 billion tons of ice since 1961, raising water levels by 27 millimeters worldwide.
