Albedo and surface temperature of the Earth

  1. Aug 19, 2010 #1
    1. The problem statement, all variables and given/known data
    If the Earth's average cloud cover increased, what effect would it have on the albedo temperature?

    If the Earths albedo increased to 0.32, what would be the average temperature?

    Ok I thought that if the albedo was higher, it would reflect more light, thus coolign would happen. But the formulas and equations are contradicting this, does anyone know why.

    BTW we r using T=((S/4*sigma)(1-alpha))^1/4... for 0.3 albedo i got 15.45 deg C, which is good then 0.32 I got 17.3 deg C.

    Im just really confused with this. Please can someone help

    oh sorry i got the temperature conversions wrong.. K-273 not 273-K
