Fig. 2: PM2.5 response to GHG-induced warming and the contribution from organic aerosol in two model subsets.

Multi-model mean annual mean a PM2.5 and b OA PM2.5 response [μgāmā3] in five models with climate-dependent BVOC emissions (BVOC models); and c, d the corresponding response in eight models that lack climate-dependent BVOC emissions (NOBVOC models). Dots represent a significant response at the 90% confidence level based on a two-tailed pooled t-test.
