On May 2, 2000, this false-color image of a Patagonian glacier was taken by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). Vegetation is signified by red in this photo. A recent study of the ice fields in Patagonia reveals that ice fields are retreating because of climate change — but not entirely because of warming temperatures.
Sébastien Bertrand of Renard Centre of Marine Geology, Ghent University in Belgium led a study of the glaciers. As he told Science Daily, the retreat also “seems to be driven by a decrease in winter precipitation, snow, rather than by an increase in temperature.” Experts expect this revelation to improve scientific understand of how climate change is impacting these glaciers.
