Which one of the following is a greenhouse gas

Methane is a strong greenhouse gas and has much higher heat trapping ability compared to carbon dioxide though its concentration is lower in the atmosphere. It is released from agriculture rice paddies and livestock digestion as well as fossil fuel extraction and waste management. Methane plays a major role in global warming by enhancing the greenhouse effect that increases the earth average temperature. Controlling methane emissions is essential for slowing down climate change. Scientists and policymakers focus on reducing methane leakage from oil and gas pipelines and improving agricultural methods to cut emissions and improve environmental sustainability.
