A new study in Science to be published 13 January identifies 14 fast action measures to reduce air pollutants that can deliver major benefits for climate, public health, and agriculture. The measures reduce emissions of black carbon and ground-level ozone, preventing 0.5°C of warming by 2050, half of the warming otherwise expected. The reductions in ozone are achieved by cutting its precursor methane. The 14 measures also save up to 4.7 million lives per year, while increasing crop yields up to 135 billion metric tons.
