Evaporated Water Can Cool Earth Surface – Report


According to the findings of the Indian Institute of Science, the Carnegie Institution for Science at Stanford University and Lawrence Berkeley National Laboratory, the evaporated water from the surface of the trees and irrigational crops could lead to cooling of the surface of the earth to a large extent and this could be a beaming factor to the reduction of increasing deforestation and to some extent a reduction of global warming.
“It is well known that clearing of forests for agriculture and infrastructure development can contribute to local warming by decreasing local evaporative cooling, but it was not understood whether this decreased evaporation would also contribute to global warming,” Govindasamy Bala of the Centre for Atmospheric and Oceanic Sciences, IISc Bangalore told PTI.
Conserving the basic law of Physics which means that no energy can be created or destroyed, only moving of energy from one place to another is the fundamental principal of operation of this cycle. This principle or you call it a fact had been recognized much long before but its impact that seems soaring high to the global warming level was never known before.
According to a experienced professor, enhanced evaporation from the surface of the earth leads to the formation of low level clouds on the surface of the earth. These clouds then scatter around but reflect more radiations towards the sun rather than on the earth. Because of reduced trans evaporation in the tropical areas caused due to deforestation, planting trees in these areas would prove more beneficial and sufficing to save the planet!
Before carrying out detailed implementations of the plan, a simulation model called general circulation model was tried and tested on supercomputers to find out the efficiency of overall process. This model contained detailed structures of many parts like full representation for atmospheric processes such as air circulation and transport of heat and water vapour, clouds, evaporation from oceans and soils, transpiration from plants, ‘radiative’ heating by solar radiation and greenhouse warming effect by carbon dioxide and other trace gases in the atmosphere making it apt for this technique.
