Among the following statements which statement is incorrect?
1 Increase in the level of greenhouse gases has led to considerable heating of Earth leading to global warming.
2 During the past century, the temperature of Earth has increased by \({\rm{1}}{\rm{.6}}{{\rm{0}}^{\rm{o}}}{\rm{C}}\), most of it during the last three decades.
3 Scientists believe that the rise in temperature is leading to deleterious changes in the environment and resulting in odd climatic changes (e.g. El Nino effect), causing increased melting of polar ice caps as well as of other places like the Himalayan snow caps.
4 All are correct.
Explanation:
During the past century, the temperature of Earth has increased by \(0.6^{\circ} \mathrm{C}\), most of it during the last three decades.

After absorbing long wave (infrared) radiation from earth, Green house gases emit those radiations
1 Outside atmosphere
2 Away from earth
3 Towards earth
4 None of the above
Explanation:

Select one among the following strategies which is not a correct approach to reduce global warming?
1 Cutting down the trees and increase the human population
2 Cutting down the use of fossil fuels
3 Reducing deforestation
4 Improving efficiency of energy use
