Consequently, you would expect a transition period in which the cooling influence of aerosols had disappeared but the warming influence of additional greenhouse gases was still present. (climatesight.org)
It's plausible the HIST coupled simulations underestimate the cooling influence of aerosols in the Pacific over the past 20 years and that would explain some of the difference alongside what appears to be a clear signal of internal variability. (tamino.wordpress.com)
But if there is no change in dimming, no change in cloud cover and little influence of aerosols in Australia (and Antarctica), there may be no connection between these all. (realclimate.org)
