Water that evaporates from vegetation turned out to have a big hand in lowering global temperatures. Recent research Carnegie's Department of Global Ecology in Stanford, United States, concluded that water evaporation helps cool the earth's tree as a whole, not just the local area.
The team of researchers from institutions that demonstrate that the evaporation or vaporization of trees and lakes can create a cooling effect on the entire atmosphere. Evaporative cooling is the process when an area is cooled by the energy used in the process of evaporation.
The researchers speculate that evaporation has a warming effect in the global climate because water vapor acts as a greenhouse gas in the atmosphere. The energy taken in the evaporated water is released back into the environment when water vapor condenses and falls back to earth as rain.
The research team used climate modeling to find that the increased evaporation has a cooling effect on global climate. Increased evaporation tends to cause the formation of low clouds in the atmosphere, which reflect sunlight back on to the space. This affects the cooling.
"Evaporation of water from the trees and lakes in urban areas not only helps keep the city stay cool, but also keeping the planet cool," said Ken Caldeira of the Carnegie. *** [SCIENCEDAILY | KORAN TEMPO 3652]
