Geo Engineering to fight Climate Change?
The Economic Times in October 2011 carried a very intriguing article on 'Geo Engineering', which I have been unable to put out of my mind for the past few weeks. After reading the article, I felt the arguments that we all are making to fight Climate Change may very well change their context in face of the various proposed Geo Engineering techniques that can be applied for cooling Mother Earth! Scientists are currently working on such techniques that will ensure that we keep away the 'heating' solar radiation from reaching the earth. Techniques like installing mirrors in the space to reflect solar radiation or seeding the upper stratosphere with sulphate aerosols or simply salt water to reflect the sun's radiations back into space. Further, other techniques that will ensure more absorption of carbon dioxide by trees and oceans are being proposed and tested for results. Some of these include infusing the oceans with calcium hydroxide so that they can take in more a...
