Shorter-lived

Carbon dioxide emissions produced by burning fossil fuels are the major cause of global warming, so efforts to combat climate change have focused on ways to cut CO₂ releases. But according to the new study published this week in the journal Science, a quicker and more effective strategy would be to reduce emissions of other, shorter-lived air pollutants. The measures would not just slow climate change, but also boost crop yields, save money, and save lives.
