Evidence of Melting of Glaciers In the Andes Mountains of South America

The melting of the glaciers throughout the Andes Mountains of South America presents one of the clearest evidence of global warming. In Bolivia, it is estimated that the glaciers have shrunk by 60 percent since 1978. In Venezuela, the glaciers have all but disappeared. One estimate is that the Andean glaciers overall have shrunk by 30 percent or more in the last 25 years.
