Which of these gases is considered a significant greenhouse gas contributing to climate change?

Methane is considered a significant greenhouse gas contributing to climate change due to its potent heat-trapping ability in the atmosphere. While carbon dioxide is the most prevalent greenhouse gas, methane is more effective at trapping heat, making it over 25 times more impactful over a 100-year period. Methane is released during the production and transport of coal, oil, and natural gas, as well as from livestock and other agricultural practices, landfills, and natural sources like wetlands. Its ability to absorb heat and contribute to the greenhouse effect significantly accelerates global warming and climate change. Understanding the role of methane in the greenhouse gas emissions is crucial for developing strategies aimed at mitigating climate change impacts.
