Abstract The entropy budget is calculated of the coupled
atmosphere­ocean general circulation model HadCM3.
Estimates of the different entropy sources and sinks of the
climate system are obtained directly from the diabatic
heating terms, and an approximate estimate of the plane-
tary entropy production is also provided. The rate of
material entropy production of the climate system is found
to be *50 mW m-2
K-1
, a value intermediate in the
range 30­70 mW m-2
K-1
previously reported from dif-
