Tiny particles of plastic in the atmosphere can affect Earth’s climate, according to Laura Revell at the University of Canterbury in New Zealand and colleagues. Yet even as airborne microplastics become an ever-larger part of the mix of atmospheric aerosols, their radiative influence is still virtually unknown. Altitude matters.
