I've never understood why changing the albedo of an object will change the temperature of the object. As I understand it the albedo is a factor that determines the amount of light reflected off the surface. This means that a low albedo will mean that more light-energy is absorbed. Thermal equilibrium is then achieved when absorbed light-energy equals the energy lost through black-body radiation, determining the temperature. However I've read in an introductory geophysics book the black-body radiation is modified by the exact same factor (I think there was even a simple convincing proof), so that a low-albedo object will radiate at a higher rate. I've haven't been able to find any other sources on the matter. In this case the factor will cancel out, yielding the same temperature, albeit at a slower equilibrium time. I've even simulated this on a computer once. So what's up!? I'm really puzzled by this.
