The Montreal Protocol, which banned most uses of ozone-destroying chemicals known as chlorofluorocarbons (CFCs) and called for their global phase-out by 2010, has been a great success story: Earth’s ozone layer is projected to recover by the 2060s. Read the full story in Nature.

True, methane is a potent greenhouse gas. But it’s also a short-lived one, which only stays in the atmosphere for twenty years or so. Because methane contributes to ozone pollution, emissions cause immediate health effects as well as warming effects. That warming could trigger other greenhouse gas emissions.

Over a 20 year period, methane is estimated to be more than 80 times as potent as carbon dioxide in terms of trapping heat in the atmosphere. This makes methane reduction crucial for addressing the urgency of climate change and buying time for the development and implementation of longer term greenhouse gas strategies.
