    Concerns about climate change, health

    A team of researchers led by James G. Anderson, the Philip S. Weld Professor of Atmospheric Chemistry, warns that a newly discovered connection between climate change and depletion of the ozone layer over the U.S. could allow more damaging ultraviolet (UV) radiation to reach the Earth’s surface, leading to increased incidence of skin cancer.
