Summary of the Cordillera Blanca Environmental Expedition 2011 Black Carbon Study
—Dr. Carl Schmitt, National Center for Atmospheric Research
The glaciers in the Cordillera Blanca have been receding rapidly over the past several decades. In addition to climatic changes, ice mass loss may have been enhanced by particulates in the snow. Black carbon in snow and glacial ice is of particular interest because the bulk of atmospheric black carbon is from anthropogenic sources and it is very efficient at increasing the rate at which glaciers melt. Common sources of black carbon are fires (from agricultural burning in the vicinity) as well as industry including transportation. Diesel engines are large sources of black carbon particulates, especially if they are poorly tuned. Download the full report.
