Methane: A Potent Yet Short-Lived Climate Pollutant
Key Points:
1. Chemical Composition: Methane (CH4) is an organic compound comprising one carbon and four hydrogen atoms.
2. Recent Attention: Gaining focus due to its significant impact on global warming, surpassing carbon dioxide in potency.
3. Global Warming Potential (GWP):** Methane has a GWP100 of 28, far exceeding carbon dioxide's GWP100 of 1.
4. COP-28 Initiative: At the UAE climate talks, philanthropic organizations like Sequoia Climate Foundation and Bezos Earth Fund pledged $450 million to mitigate methane emissions.
5. Lifespan in Atmosphere: Unlike carbon dioxide's decades-long presence, methane breaks down within years, classifying it as a short-lived climate pollutant.
6. Emission Sources: Includes cattle farming, landfills, wastewater treatment, rice cultivation, and certain industrial activities.
7. Importance in Climate Discussions: Increasing acknowledgment of methane's role in climate change, necessitating targeted emission reduction strategies.
