Methane: The Overlooked Climate Lever That Could Decide the 2°C Target

When the conversation turns to global warming, carbon dioxide usually dominates the headlines. Yet methane deserves just as much attention. It ranks as the second-biggest driver of climate change, and although it lingers in the atmosphere for only a few decades, it captures heat far more aggressively than CO2 while it is there.

That combination — intense short-term warming paired with a brief lifespan — is exactly what makes methane such a strategic target. Agriculture and fossil fuel operations are among the main human sources of these emissions. Because the gas fades relatively quickly, cutting methane now could deliver measurable relief within a single generation rather than centuries down the road.

For the world to keep warming “well below” 2°C, as outlined in international climate goals, methane reductions cannot remain a footnote. They belong alongside — not behind — long-term carbon strategies. The payoff is fast, and the window to act is narrow.
