A recent study published in Environmental Science: Atmospheres  revealed that nanoplastics — tiny particles from degraded ocean plastics — can disrupt fatty-acid films at the ocean’s surface, which play a key role in how gases and particles move between the ocean and the atmosphere. These changes may affect the formation and behavior of sea spray aerosols, which influence cloud formation and climate processes. The research highlights a new potential pathway for plastic pollution to impact our climate. This paper was funded in part by The Herbert W. Hoover Foundation and featured on the issue cover of Environmental Science: Atmospheres.
