Methane

Definition

Methane is a potent greenhouse gas (GHG) that is released into the atmosphere through natural processes and human activities. It has a much higher warming potential than carbon dioxide, although its atmospheric concentration is lower.

Analogy

Imagine methane as a sneaky heat-trapping gas. Just like a small spark can start a big fire, even small amounts of methane can have a significant impact on global warming due to its high potency as a greenhouse gas.

Related terms

Methanogenesis: Methanogenesis refers to the production of methane by microorganisms in anaerobic environments such as wetlands and the digestive systems of animals.

Landfills: Landfills are sites where waste materials are disposed of and decompose over time. They produce methane as organic matter breaks down without oxygen.

Permafrost: Permafrost is permanently frozen ground found in Arctic regions. As permafrost thaws due to climate change, it releases trapped methane, further contributing to global warming.
