Why methane is the most urgent lever for cooling our planet

Ilissa Ocko: The fastest way to slow climate change now · 10:21 · Video: TED · Watch at the source

In short: While carbon dioxide dominates the long-term climate conversation, atmospheric scientist Ilissa Ocko argues that methane offers a much faster way to mitigate warming risks right now. This video explores why targeting methane is the most effective near-term strategy for climate action.

Unlike carbon dioxide, which builds up gradually over time, methane's warming impact is driven almost entirely by recent emissions. This distinction makes it a primary target for rapid intervention. Ocko identifies three main sources of methane pollution that, if addressed, could significantly decelerate global warming within a matter of years rather than decades.

The core concept is what Ocko calls the "methane moment": the realization that we have a unique opportunity to see immediate results by tackling specific, high-impact pollution sources.
