Question

Contribution of methane to global warming is

• A. 6%
• B. 14%
• C. 20%
• D. 30%

Answer 1

The correct option is C 20%

The poisonous gases released in the environment traps the radiations on the earth and increases temperature which leads to global warming. Methane is a more potent greenhouse gas than $C{O}_2$, there is over 200 times more $C{O}_2$ in the atmosphere. For example $C{O}_2$ levels are 380 ppm (parts per million), while methane levels are 1.75 ppm. Hence, the amount of warming methane contributes is calculated at 20% of the warming $C{O}_2$ contributes.
