The group also used a
general circulation model to predict what might be expected to happen in the world's wine locales in the next 50
years and determined that an average additional warming
of two degrees C may occur.
In the study, researchers analyzed a series
of transient Coupled
General Circulation Model simulations forced by changes in greenhouse gases, orbital forcing, meltwater discharge and the ice - sheet history throughout the past 21,000
years.
This
year we received 14 June SIO submissions from dynamical
models,
of which 3 were from ice - ocean
models forced by atmospheric reanalysis or other atmospheric
model output and 12 were from fully - coupled
general circulation models.
The Met Office Hadley Centre (Hadley Centre for Climate Prediction and Research) climate change

As noted in that post, RealClimate defines the Atlantic Multidecadal Oscillation («AMO») as, «A multidecadal (50 - 80
year timescale) pattern
of North Atlantic ocean - atmosphere variability whose existence has been argued for based on statistical analyses
of observational and proxy climate data, and coupled Atmosphere - Ocean
General Circulation Model («AOGCM») simulations.
How ARM came to be: After 25
years in action, ARM is still in the business
of bettering the performance
of the climate science's
general circulation models.

GCMs (
General Circulation Models) took about 1 day
of machine time to cover 25
years.
As we now that there has been a period
of 18
years with no surface warming when atmospheric CO2 was increasing for each and every
year we know that the majority
of the warming in the last 50
years was not due to the increase in atmospheric CO2 and the IPCC
general circulation model calculated warming due to CO2 is orders
of magnitude too high.
Here we use a coupled atmosphere - ocean
general circulation model to simulate the climate
of the mid-Pliocene warm period (about three million
years ago), and analyse the forcings and feedbacks that contributed to the relatively warm temperatures.
