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.

It's an optimistic glimpse into a future where global cooperation and cutting-edge monitoring could rapidly slow climate change.
