We all know that black occurs in the absence of
light and black is
actually the absorption of all color which is why we wear black on cold days to
absorb as much sunlight and heat as possible and white (which reflects
light and heat) on hot days.
Bobby, I believe most of the heat is
absorbed and
light that reflects would likely be sent right back out to space - granted some of it would hit clouds and turn to some heat there, but generally, the
light that hits the earth now stays on the earth - if it's reflected back out to space as
light then that's where it goes, back out to space and therefore it would
actually cool the earth more to reflect it back to space.
