The best way to lower Earth’s temperature — fast | Daniel Zavala-Araiza

There's an invisible super-pollutant heating up the planet — but it's surprisingly easy to reduce, if we try. Revealing how methane contributes (way) more in the short term to global warming than carbon dioxide, chemical engineer Daniel Zavala-Araiza highlights the emerging technologies and bold new policies that are part of a worldwide effort to hold oil and gas companies accountable for polluting our skies with this harmful gas. It's an optimistic glimpse into a future where global cooperation and cutting-edge monitoring could rapidly slow climate change.
