Ships Once Painted Invisible Rivers Across the Sky

Ship tracks are bright, linear clouds that form when particles from ship exhaust help cloud droplets form over the ocean. They make a normally invisible human influence visible from space. Editorial note: one track is not a climate-control switch; the climate effect of ship aerosols depends on weather, emissions and cloud conditions across large regions.
