Climate Variability on Venus and Titan

Venus and Titan are both slowly-rotating, approximately Earth-sized bodies with cloudy, dynamic atmospheres. Each has a complex climate system, even less well understood than the terrestrial equivalent, and the processes that appear to maintain the climate near the surface on both bodies have interesting similarities and differences with each other and with the Earth. By considering these factors and their possible evolution with the aid of elementary climate models, some interesting, albeit tentative, conclusions can be reached concerning the stability of climate on Earth-like planets, and the likely nature of past and future climate change.
