Periodic Climate Forcing, or How to Determine a Planet's Climate from Very Far Away

The three most important periodic climate forcings are: the day-night cycle (due to a planet's rotation), 2) eccentricity seasons (due to its non-circular orbit), and 3) obliquity seasons (caused by a tilted spin axis).  I will describe how a planet's heat storage and heat transport affect its response to these forcings.  I will then describe how these three forcings can be observed in extrasolar planetary systems, and what this tells us about these distant world's climate.
