Question

Which gas is/are responsible for Global warming?

• A. Oxygen
• B. Carbon dioxide
• C. Water vapour
• D. Methane

Answer 1

Answer: (B), (C), (D)

The correct options are

B

Carbon dioxide

C

Water vapour

D

Methane

Carbon dioxide, water vapour, and methane are the primary greenhouse gases that are responsible for global warming.

Global warming is caused by the emission of greenhouse gases. 72% of the totally emitted greenhouse gases are

• Carbon dioxide ($C{O}_2$),

• 18% methane and

• 9% nitrous oxide (Nox).

Carbon dioxide emissions, therefore, are the most important cause of global warming. $C{O}_2$ is inevitably created by burning fuels like e.g. oil, natural gas, diesel, organic - diesel, petrol, organic - petrol and ethanol.
