The authors present model studies related to the general question of whether there could have been nearly ice-free climates in the past history of the Earth. Energy balance models and general circulation model calculations have addressed this question. In general this appears impossible, even with moving continents around, without postulating enhanced levels of CO[sub 2]. Early work indicated that pole centered continents could have snow free summers, but later work, with models with better physics, but poorer resolution seemed to contradict this conclusion. The authors apply the GENESIS (ver 1.02) general circulation model to this problem. Their conclusion is that with certain modifications to the application of this model, they could find pole-centered supercontinents which would be snow free in the summer.
