On average, how do high clouds affect the surface temperature (compared to a clear
sky)?
(a) High clouds warm the surface by increasing the greenhouse effect
(b) High clouds cool the surface by increasing the energy emitted to space
(c) High clouds cool the surface by increasing the albedo
(d) It depends on whether they are comprised of ice or liquid water
