Abstract -

Finding just one example of a biosphere beyond the solar system would  
not only place real constraints on life's cosmic abundance and  
origins, but also allow us to place the Earth in proper context. To do  
this we need to search for astronomically visible, surface dominant,  
living systems. One step towards this is the process of evaluating the  
physical and biological environments of a diversity of rocky worlds to  
understand their climatological states. Along the way we need to  
better constrain the orbital behavior of observed exoplanetary  
systems. I'll review some developing work that attempts to meld  
state-of-the-art climate modeling with very high precision simulation  
of planetary spin-orbit behavior, with the goal of tracking down  
living worlds.
