Re-evaluating pre-industrial aerosol concentrations

Model simulations find that atmospheric particle formation involving only biogenic vapors may have been the dominant aerosol formation process in the pre-industrial lower atmosphere, and may lead to a 27% reduction in estimates of anthropogenic aerosol climate forcing, according to a study. - Read at PNAS.org
