How to tackle the climate, health and food crises, all at the same time.
From coal mines to rice paddies and cooking fires to diesel exhausts, 14 highly cost-effective measures could quickly curb global warming and save millions of lives, while also boosting global food production. That is the striking conclusion of a new study published in Science and the most authoritative look yet at the opportunities offered in tackling methane and black carbon – soot – pollution.
The headline findings are striking. The measures would reduce warming by 0.5C by 2050, very useful indeed with the world failing to get to grips with carbon dioxide emissions. And that’s only half the tale. They would also avert between 0.7 and 4.7 million premature deaths caused by air pollution every year and bump up crop yields by 30 to 135m tonnes a year.
