Methane is a colorless, odorless gas that is the main component of natural gas. It is a greenhouse gas that is released into the atmosphere through natural processes such as the decomposition of organic matter and human activities such as agriculture, fossil fuel extraction, and waste management. Methane is a potent greenhouse gas, with a much higher global warming potential than carbon dioxide, although it has a shorter atmospheric lifetime. Efforts to reduce methane emissions are important in addressing climate change.

Methane
Chemical Formula: CH4
Properties:
- Colorless, odorless, flammable gas
- Boiling point: -161.6 °C
- Melting point: -182.5 °C
- Density: 0.717 g/L
- Soluble in water (22.7 mL/100 mL at 25 °C)
Occurrence:
- Naturally occurring greenhouse gas found in the atmosphere
- Produced by anaerobic decomposition of organic matter in wetlands, landfills, and animal digestive systems
Sources:
- Natural: Wetlands, rice paddies, wildfires, enteric fermentation in livestock
- Anthropogenic: Fossil fuel extraction and transportation, agriculture, landfills, waste treatment
Environmental Impact:
- Greenhouse gas: Methane is a potent greenhouse gas with a global warming potential 25 times higher than carbon dioxide.
- Air pollution: Methane can react with other chemicals in the atmosphere to form smog and ground-level ozone.
- Climate change: Increased methane levels contribute to climate change by trapping heat in the atmosphere.
Uses:
- Natural gas (primarily methane) is an important fuel source for heating, cooking, and electricity generation.
- Used as a feedstock for the production of chemicals, such as methanol, ammonia, and plastics.
- Used as a refrigerant in cooling systems.
Mitigation:
- Reducing methane emissions is crucial for mitigating climate change. Strategies include:
- Improving waste management practices in landfills and agriculture
- Capturing and utilizing methane from anaerobic digesters
- Reducing enteric fermentation in livestock
- Promoting renewable energy sources
Other Facts:
- Methane is the main component of natural gas and biogas.
- It is also known as marsh gas due to its common occurrence in wetlands.
- Methane is a simple hydrocarbon molecule with a tetrahedral shape.
- On other planets, such as Mars and Jupiter, methane has been detected in the atmosphere.
