For example, they
predicted the expansion of the Hadley cells, the poleward movement of storm tracks, the rising of the tropopause, the rising of the effective radiating altitude, the
circulation of aerosols in the atmosphere, the
modelling of the transmission of radiation through the atmosphere, the clear sky super greenhouse effect that results from increased water vapor in the tropics, the near constancy of relative humidity, and polar amplification, the cooling of the stratosphere while the troposphere warmed.
This is followed by the authors» conclusion that while simple
models (which consider only carbon chemistry)
predict that the ocean will take up 70 - 80 % of the carbon dioxide we emit, the long - equilibrium will quite possibly be considerably higher than those
models would suggest — given the changes to ocean
circulation.
For example, do climate
models predict jumps between states of climatic
circulation, either atmospheric or oceanic?

predicted by any of those theories (see also Lee and Mak 1996 or discussion in Chang et al. 2002).
You'll need to be okay with not understanding why CO2 lags temperature, why its
predicted effects do not match observed climate measurements, or why the IPCC's general
circulation models can not
predict short - term, regional, or even past climate changes accurately.
Because radiative forcing, while it does vary somewhat with vertical profile, is relatively immune to changes of the atmosphere due to
circulation, so
models can do a reasonable job of
