Climate scientist Kevin Trenberth also notes that the change in the estimated aerosol forcing is mainly associated with indirect aerosol effects, but half of GCMs don't include these indirect effects, and those that do actually tend to
simulate less warming.

When the researchers
simulated a second effect of climate change in addition to
warming, namely drought, the results were even the opposite as expected: The soil animals ate
less, and also the microorganisms living in the soil showed a decline in respiration — an indication that they also consumed
less food.
... it is sometimes argued that the severity of model - projected global
warming can be taken
less seriously on the grounds that models fail to
simulate the current climate sufficiently accurately.
Coupled models
simulate much
less warming over the 20th century in response to solar forcing alone than to greenhouse gas forcing (Cubasch et al., 1997; Broccoli et al., 2003; Meehl et al., 2004), independent of which solar forcing reconstruction is used (Chapter 2).
Fyfe and colleagues (2013) find that the observed
warming over the periods 1993 - 2012 and 1998 - 2012 is significantly
less than the
warming in climate model simulations, but that the same models successfully
simulate the rate of
warming over the 1900 - 2012 period.
It elected not to
simulate an amplifying effect, much
less introduce dynamic cloud feedback to
warming and solar radiation.
The observed rate of
warming given above is
less than half of this
simulated rate, and only a few simulations provide
warming trends within the range of observational uncertainty.
A small area of
less warm water in the North Atlantic Ocean is
simulated for JJA, and the
warming is slightly greater than in DJF.
