The proposal to ward off global warming by cooling earth artificially could lead to climate disorder like drought in poorest countries, particularly in Africa, Asia and South America, warn scientists.
The Geo-engineering plan involves injecting small reflective sulphate particles into the upper atmosphere to decrease incoming solar radiation, the Independent reported.
AdvertisementAndrew Charlton-Perez of the University of Reading said that the study shows that one of the leading candidates for geo-engineering could cause a new unintended side-effect over a large part of the planet.
Charlton-Perez said that the risks from this kind of geo-engineering are huge like a reduction in tropical rainfall of 30 percent would, for example, quickly dry out Indonesia so much that even the wettest years after a man-made intervention would be equal to drought conditions now.
The ecosystems of the tropics are among the most fragile on earth and if such plans are executed, changes would happen so quickly that there would be little time for people to adapt, he added.
