This allows us to make reasonable a ssumptions as to the true biological potential of exoplanets. I then apply these principles to derive ecological models, which areīased on terrestrial observations. Finally, the role of geophysical processes in determining the geographical landscape is considered.
Integrating these observations introduces some significant impacts on habitability.

Consequently, I have made some reasonable suggestions how to do this, by adapting these models to incorporate terrestrial observations. What still lacks in this area are circulation models for realistic planets with both land and sea.
This book fully explores various atmospheric models and then applies them to address habitability. There is an expansion of the discussion of planetary atmospheres and their impact on life from an earlier book I wrote. This has allowed for a more formal investigation of planetary evolution and what this means for the long-term survival and evolution of life on these worlds. A considerable body of new work has emerged in recent years. Therefore, in this book, there is a detailed dissection of stellar and planetary evolution, but with a greater emphasis on the internal workings of the planets themselves. In recent years, the concept of habitability has evolved from a simple concept that concerns solely the circumstellar habitable zone to one that embodies a greater range of relevant variables. The reasons are relatively straightforward but not entirely obvious from first expectations. Without giving too much away, the outcome of these experiments has proved less positive than I initially imagined in 2013. I wondered whether one could merge ecological and evolutionary principles with geophysics and astrophysics to provide a clearer picture of the true likelihood of complex biological life emerging on such planets. Since the publication of Under a Crimson Sun in 2013, I have begun to investigate the biological potential of such planets, carving out something of an appropriate niche in astrobiology. Since this time, the number of planetary discoveries has skyrocketed, as have the number of questions surrounding whether the planets of red dwarfs are habitable or not. Moreover, atmospheric modeling was fairly simplistic, and such models applied principally to water planets. Of these, only Gliese 581and Gliese 667C were (modestly) characterized. In 2011, when I first proposed Under a Crimson Sun, few planets had been discovered in orbit around red dwarf stars. To my adored, beautiful wife, who is a constant sense of inspiration and support.
