Their findings are particularly significant because glaciers in the tropics, 99 percent of which are in the Andes, are regarded as among the most sensitive indicators of climate change on the planet, according to the Intergovernmental Panel on Climate Change (IPCC).

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.
