Q. Consider the following statements:
1.Methane has a greater potential than carbon dioxide in causing global warming.
2.Methane has large number of emitting sources than carbon dioxide.
3.The Methane Alert and Response System (MARS) will integrate data from existing and future satellites that have the ability to detect methane emission events anywhere in the world.
Which of the statements given above are correct?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: C
Notes:

Statement 1: Methane is far more dangerous than carbon dioxide in its potential to cause global warming. Methane is blamed for having caused at least 25 to 30 per cent of temperature rise since the pre-industrial times.

Statement 2: The statement is incorrect. Methane unlike carbon dioxide, is largely a sectoral gas, and there are only a few sources of emission.

Statement 3: The Methane Alert and Response System, or MARS, will integrate data from a large number of existing and future satellites that have the ability to detect methane emission events anywhere in the world, and send out notifications to the relevant stakeholders to act on it.
