Scientists have long debated about the impact on global climate of water evaporated from vegetation. New research concludes that evaporated water helps cool the earth as a whole, not just the local area of evaporation, demonstrating that evaporation of water from trees and lakes could have a cooling effect on the entire atmosphere. These findings have major implications for land-use decision making.
