Why is methane called greenhouse gases?
Methane is called a greenhouse gas because it contributes to the greenhouse effect, which is the trapping of heat in the Earth's atmosphere. It is a powerful greenhouse gas, being 25 times more potent than carbon dioxide in trapping heat over a 100-year time horizon . Methane is released into the atmosphere from various sources, including natural wetlands, paddy rice fields, livestock production systems, biomass burning, anaerobic decomposition of organic waste in landfills, and fossil fuel exploration and transport . Human activities, such as the expansion of paddy rice cultivation, livestock production, and fossil fuel exploration, have increased the concentration of methane in the atmosphere . Methane is also stored beneath the ocean floor in a stable form called hydrate, and the melting of these hydrates due to global warming can release more methane from the ocean floor . Overall, methane's significant contribution to the greenhouse effect and its sources make it an important greenhouse gas to consider in climate change mitigation efforts .
