5) Ocean fertilization- Published on 28 Aug 15a. Only 1 and 2
b. Only 1, 2, 3 and 5
c. Only 1, 3 and 4
d. All of the above
ANSWER: All of the above
Apart from Adaptation and mitigation, geo - engineering is another strategy to tackle climate change. Scientists suggest geo - engineering as a supplementary strategy and not a sole method to be adopted as the effects it has in the long term is not known. It is also very costly and risky. No known large-scale climate engineering projects have taken place to date. All the strategies are either theories or computer models or in nascent stage of small scale testing mode.
