Consider the following statements with respect to Green house gases:

Water vapour is the most potent of the greenhouse gases in Earth’s atmosphere.

Methane(CH4) is more potent than CO_2.

Which of the above statements is/are correct?

Question

Water vapor is the most abundant and potent greenhouse gas in the Earth\'s atmosphere. While its atmospheric lifetime is short, water vapor accounts for around 50% of the total greenhouse effect on Earth.
Methane is estimated to be 20-30 times more potent than carbon dioxide as a greenhouse gas over a 100 year timescale. This is because of its high global warming potential and ability to absorb infrared radiation efficiently.
