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