I'm concerned as most other people when it comes to global warming. So it is believed that carbon dioxide has a major affect on the earths warming but what about other factors that maybe even bigger than CO2. Ever layed in a field with green grass under a shady tree on a hot summers day and felt cool? But when on the city street surrounded by tarmac and sitting under a man made bus shelter on a hot summers day it is stinking hot still?
Well its the natural evaporation from the grass and trees that cools the air around the tree. Across the world urban sprawl is huge removing the trees and grass (earths natuarl air conditioning system) laying tarmac, tiled and tin rooves all which retain heat.
So should we be looking at better reflective surfaces for our buildings?
Ones which reflect radiation rather than absorb it?
painting roads white and having white rooves on all the buildings and houses around the world might have a greater effect than reducing CO2.
