Arctic Cloud Factory Discovered | Science News
Scientists have uncovered a hidden Arctic cloud factory that could dramatically alter climate predictions: as sea ice melts, sunlight triggers chemical reactions between ocean compounds, algae, and ice to multiply cloud-seeding particles by up to fifty times in a single day. This process, observed on 80% of sunny days during a 2022 expedition, involves newly identified iodine-containing molecules that help tiny particles grow into actual clouds. Since the Arctic is warming faster than anywhere else on Earth, and this phenomenon expands as ice retreats, its absence from current climate models…
