Methane leads to both global warming and photochemical smog. Order of contribution of global warming gas
Order of contribution of global warming gas
- Methane is generated in large amounts from paddy fields. CH4 is 40 times stronger greenhouse gas than CO2.
- CO2 can be absorbed by photosynthesis or by formation of acid rain etc., while no such activities are there for methane.
- It has more heating effects. Hence, methane is stronger global warming gas than CO2.
- Methane is not a part of reducing smog.
Hence, statements (A),(B) and (C) are true.
