    Re: More sunlight in Greenland than in the Amazon
    From: Nick M

    It is surprising. It confuses me, much like the statement "hot water freezes faster than cold water." One time, in the Arctic at -50F, I set two of the same containers of water outside, one was boiling and the other was water that I boiled but had cooled to about 35F in the refrigererator. Despite what the science says, the cold one froze first...maybe in a lab the science works more favorably.

    Based on the sunlight chart, I shouldn't enjoy a SAD light in winter in the Arctic...yet it seems to help. Are their calculations misleading because in summer they get 24 hours of sunlight while in the winter, they get 6 hours of sunlight? That makes the Arctic average (24+6 = 30/2 =15) sunlight greater than the Amazon because the Amazon only gets around 12 hours per day. I can tell you that if I fell in to the water in the Arctic, at any time of year, it's much different than falling in to tropical water at any time of year. When that happens though, the biggest difference to me would be the magnitude of the sun.
