Soot's global impact on atmospheric warming: NASA researchers found the amount of sunlight absorbed by soot is two-to-four times larger than previously assumed. Reducing sulfates without reducing soot will exacerbate soot's effect because sulfates' high reflectivity index (albedo) counterbalances soot's heat-trapping effect to varying degrees. ..and... "...The calculated global warming in an 1880-2000 simulation is about one-quarter of observed global warming." ..and.. 90 percent of Arctic warming is due to soot causing dirty snow. |
