Abstract We assess 19 coupled models from the IPCC fourth assessment report archive from the simulation of the 20th century, based on the calculation of "skill scores". The models show a wide range of scores when assessed against Antarctic or global measures of large- scale circulation indices. Except for continental mass balance, the model average proves a more reliable estimate than that for any one model. Individual models show a very wide scatter in simulated Antarctic temperature trends over the past century. (mod. journ. abst.)
