What the world must do to tame methane

Methane is a potent greenhouse gas. Over 20 years it has over 80 times the planet-cooking power of carbon dioxide, and is the culprit behind nearly 45% of warming today. Because methane is the main component of natural gas, a big chunk of man-made emissions comes from the energy industry. Yet because it is short-lived, curbing methane offers the world its best possible chance for quick progress against climate change.
