Andes’ Tropical Glaciers Going Fast
Another reason to visit as many Andean glaciers as possible. From ‘Andes’ Tropical Glaciers Going Fast’ in Climate Central:
The glaciers of the tropical Andes have shrunk by between 30 and 50 percent in 30 years and many will soon disappear altogether, cutting off the summer water supply for millions of people, according to scientists studying the region’s climate.
And more specifically for Bolivia:
In the Andes glaciers contribute to irrigation, hydroelectricity generation, and water supply. For example, 15 percent of the water consumed in La Paz, the capital of Bolivia, comes from glaciers, a figure that doubles in the summer. The region, with 3.5 million people, is heavily dependent on melt water for its survival.
