Scientists Discover a Natural Arctic Cloud Factory Missing From Climate Models

A University of Birmingham-led team found the first field evidence that melting Arctic sea ice generates cloud-forming particles where it meets open ocean, through a sunlight-driven reaction involving iodine, sulfur and organic compounds, observing a fifty-fold particle increase in a single day. The process is entirely missing from current climate models, despite its potential influence on cloud cover above a region warming faster than anywhere else on Earth.
