Research presented at the latest American Geophysical Union meeting points to carbon emissions from Asian cities as partly responsible for the 20 percent decrease in the Himalayan glaciers since the 1960s, Wired.com reports. The video above tracks black carbon through the Earth's atmosphere from August to November this year. The time of the highest concentration of black carbon over the western Tibetan Plateau coincides with the time of the fastest glacial melting in the area. Scientists say that a regional climate phenomenon is at play that accelerates local glacial melting, which could be at a higher rate than global warming from greenhouse gases.
