Impact of black carbon on climate larger than thought

soot_small.jpgSeveral key scientists* involved in MACC-II contributed to a study that shows that black carbon aerosol has a much larger impact on climate than previously thought. The study that appeared on 16 January in the American Journal of Geophysical Research - Atmospheres says that the direct influence of black carbon, or soot, on warming the climate could be about twice as large as previous estimates, including those from the last IPCC report. While the published study was not based on results from the MACC-II project, some of the co-authors are directly involved in MACC-II, working together on improving the aerosol monitoring and forecasting system. This part of the Copernicus Atmosphere service will contribute to help reduce uncertainties on black carbon and its impact on climate and air quality. The official press release about the published paper can be found at the web site of the International Geosphere-Biosphere Programme (IGBP).
