The monthly globally-averaged atmospheric methane abundance reached a record high of 1,942 parts per billion (ppb) in October 2024. Globally-averaged annual atmospheric methane concentrations have risen dramatically over the past three decades. Methane is a powerful greenhouse gas that has a far greater global warming potential (GWP) than carbon dioxide.
