Black carbon persists across the planet, accelerating glacial melt

Science
June 30 (UPI) -- New research shows black carbon deposits vary across the planet, but persist in a variety of glacial ecosystems.Black carbon is the soot-like particulate matter released by the combustion of fossil fuels, biofuel and biomass -- through man-made processes, like the burning of coal, and natural means, like wildfires.Climate scientists are interested in black carbon because deposits among snow and glaciers affect melting rates. Black soot absorbs more energy than white snow and ice.Scientists at the University of Colorado, Boulder recently conducted a global survey of black carbon deposits. Molecular analysis of the deposits helped scientists trace the sources of black carbon deposits and measure changes in deposition rates.On Greenland's ice sheet, researchers found evidence...
