Introduction
In the previous unit we discussed the equilibrium simulations of global
climate in which a model is run with the present greenhouse gas concentrations and then run again with doubled
(or in some cases quadrupled) amounts of greenhouse gases.
In each model run, the model is allowed to continue until all the effects of initial conditions have
died away and the model ocean, atmosphere,
and ice masses come into balance with the heating effects of the assumed level
of greenhouse gases. This is verified by observing that the global
temperatures are not drifting off to a warmer or colder average.
