Q. Solar Radiation Management is used as a geo-engineering technique to combat climate change. Which of the following are its components?
1. Placing Aluminum mirrors in space.
2. White painting roofs and roads.
3. Firing sulphur dioxide into atmosphere.
4. Ocean fertilization.
Select the correct answer using the codes given below:
Answer: C
Notes:
Explanation:
- Theoretically, there are two major types of interventions – Carbon Sequestration and solar radiation management.
- Solar Radiation Management techniques include firing sulphur dioxide into atmosphere, putting huge mirrors in the space, creating pale colored rooftop and other structures which have high albedo.
- Ocean fertilization is adding iron or nitrogen to the ocean to promote carbon sequestration by phyto planktons.
- Geo engineering is large-scale intervention in the Earth’s climatic system with the aim of limiting climate change.
