Document Summary

Climate results from a balance between the rate at which energy arrives at and leaves earth. How much energy we get from the sun. How much of that energy is reflected back in space (albedo: aerosols, ice, etc. ) Changes in any of these can cause a climate change. Distance and orientation of earth relative to the sun.
