We have developed a new three-dimensional climate model for the study of primitive terrestrial atmospheres and habitability. Here we discuss preliminary modeling results for the early Martian atmosphere and the recently discovered exoplanet Gl581d. For the latter, our results indicate that a sufficiently dense pure CO2 atmosphere could allow for local surface temperatures above 273 K in the warmest regions. However, without other warming mechanisms, such an atmosphere would be extremely vulnerable to collapse on the poles and/or dark side of the planet. Investigation of the effects of other gases and unknowns such as topography is currently underway.Read less <
