Soot’s Role Confirmed in Himalayan Warming

Tiny, dark-colored aerosols – specifically black carbon – travel along wind currents from Asian cities and accumulate over the Tibetan Plateau and Himalayan foothills. Seen here as a light brown mass, these brown clouds of soot absorb sunlight, creating a layer of warm air (seen in orange) that rises to higher altitudes, amplifying the melting of glaciers and snow.
