the shrubs and desert are mostly redish color and not very good at reflecting. possibly being too salty for things to grow on ? I had thought what would happen if we sprayed the trees and or sand a white or green color to reflect the sun back.
might possibly need wind simulations for it. but after looking at the ice we have left i can guess were good for 90 more years if the humidity does not get it.
egg shells could also be used possibly.
