What to know about Melting sea ice combines with Arctic sea to make clouds

Researchers from the University of Birmingham and international partners have identified a natural process in the Arctic where iodine, sulfur, and organic compounds combine at the ice edge to create cloud-forming particles. The study, published in Nature Geoscience, suggests that as sea ice melts and the marginal ice zone widens, this process may increasingly influence cloud cover and the region's radiation balance.
