Study says soot is big in warming

The tiny black particles released into the atmosphere by burning fuels are far more powerful agents of global warming than had been estimated, atmospheric scientists reported in a study issued Tuesday. These particles, which are known as black carbon and are the major component of soot, are the second most important contributor to global warming, behind carbon dioxide, wrote the 31 authors of the study, published online by the Journal of Geophysical Research-Atmospheres. The new calculation adds urgency to efforts to curb the production of black carbon, which is released primarily by diesel engines in the industrialized world and by primitive cookstoves and kerosene lamps in poorer nations. Natural phenomena like forest fires also produce it. The analysis has pushed methane to third place as a human contributor to global warming.
