The amount of warming caused by CO2 might have been masked over the years by
accompanying aerosol emissions.
Not exact matches
Also, the idea is to keep warming below +1.5 ºC even with the current energy imbalance (warming in the pipeline) and reductions in
aerosols that
accompany emissions reductions (though Hansen says the impact of
aerosols from fossil fuels was overstated and other manmade
aerosols seem to dominate).
The climate changes have been simulated by seven coupled atmosphere - ocean general circulation models (AOGCMs; see Table 1 of the
accompanying report), the greenhouse gas and
aerosol forcing being inferred from the SRES
emission scenarios A1FI, A2, B1 and B2.
Hmmm... don't suppose it occurred to anyone to check the amount of anthropogenic
aerosols that were emitted during this time frame 1940 - 1970, or the fact that
aerosols have an immediate cooling effect on troposphere temperatures that can mask the underlying warming caused by the CO2
emissions that also
accompany the
aerosols.
