Melting sea ice combines with Arctic sea to make clouds
Researchers have discovered that melting Arctic sea ice releases iodine, sulfur, and organic compounds that seed cloud formation. This natural process significantly increases cloud-forming particles, which may influence Earth's radiation balance and climate change.
Why it matters
Understanding this feedback loop is crucial for improving climate models and predicting how Arctic warming will affect global weather patterns.

In findings published Aug. 5 in Nature Geoscience , an international research team led by the University of Birmingham, including partners from China and Spain, presents the first real-world evidence that where Arctic sea ice meets the open ocean, marine life and sunlight combine to release a chemical mixture that seeds the sky with cloud-forming particles.
