Overview

• Global methane emissions have surged, with human activities responsible for over two-thirds of the total.
• Methane traps 80 times more heat than CO2 in the first two decades after reaching the atmosphere.
• Top contributors to methane emissions are agriculture, fossil fuels, and waste management.
• Efforts to cut methane emissions are underway, but recent findings indicate far more aggressive action is needed.
• Unchecked methane emissions could result in up to 3°C of warming by 2100.
