comment How is the Earth heated by a Full Moon?
*So we know that 1000 W/m2 (solar irradiance on the Earth surface) cause a temperature increase of around 10∘C. -- I'd say: we know that the solar irradiance on earth (1000 W/m2) causes it's average temperature to rise almost 300 K above the temperature of the cosmic background radiation. Makes quite a difference.
