Climate Change Affects Glacial Water Source

ThinkTV, Teachers' Domain

This video discusses how the populous areas west of the Andes are largely desert and rely on glacial meltwater as an important source of fresh water. Because the Peruvian glaciers high in the Andes are in rapid retreat, scientists are monitoring the steadily shrinking glaciers and the impact of their reduction on local populations.

Video length: 4:18 minutes.
