Basic physical science considerations, exploratory climate modeling, and the impacts of volcanic
aerosols on climate all suggest that SWCE could partially
compensate for some effects — particularly net global warming — of
increased atmospheric CO2.
While SO2 emissions may have had some small role in that period, they can't have a role in the current standstill, as the
increase of emissions in SE Asia is
compensated by the decrease in emissions in the Western world, thus there is hardly any
increase in cooling
aerosols while CO2 levels are going up at record speed and temperatures are stalled.
The (lack of) skill of the current GCM's always wondered me and I have been suspicious about the use of human
aerosols as a convenient «tuning knob» to fit the past, and even so not so good, especially not in current times where the reduction of
aerosols in the Western world is near fully
compensated by the
increase in SE Asia.
McCusker et al. (2012) performed an experiment in which global - mean surface temperature was held constant by
increasing CO2 while simultaneously
increasing sulfate
aerosol... to
compensate.
It can also strengthen the Asian summer monsoon circulation and cause a local
increase in precipitation, despite the global reduction of evaporation that
compensates aerosol radiative heating at the surface (Miller et al., 2004b).
In response to
increasing concentrations of greenhouse gases and tropospheric sulfate
aerosols, the multimodel average exhibits a positive annular trend in both hemispheres, with decreasing sea level pressure (SLP) over the pole and a
compensating increase in midlatitudes.
