Interpreting these observations will be a grand challenge\, because the diversity of rocky planet climates is likely to b e enormous. Here I discuss the role that theory and idealized modeling can play in advancing our understanding of the possibilities. I present resul ts on two key problems in exoplanet climate evolution: the loss of a plane t’s water to space and the circulation (and possible nightside collapse) o f atmospheres on tidally locked planets. I show that in both cases\, scali ng analysis allows the fundamentals of the problem to be understood in a r obust and general way. I discuss the implications of these results for exo planet habitability and the future search for biosignatures by groundand s pacebased telescopes.

I present results on two key problems in e xoplanet climate evolution: the loss of a planet’s water to space and the circulation (and possible nightside collapse) of atmospheres on tidally lo cked planets.
