Q. Consider the following statements:

1. Geoengineering refers to techniques for removing carbon dioxide from the atmosphere.
2. Geoengineering also includes methods to reduce the amount of sunlight reaching the Earth’s surface.

Which of the above statements is/are correct?
Answer: Both 1 and 2
Notes: Geoengineering comprises deliberate large-scale interventions in the Earth’s climate system, mainly through techniques that either remove carbon dioxide from the atmosphere (e.g., carbon capture, afforestation) or limit incoming solar radiation (e.g., solar radiation management by aerosols or space-based reflectors) to directly address global warming and its effects.
