Scientists are warning that a newly-discovered connection between climate change and depletion of the ozone layer over the US could allow more damaging ultraviolet (UV) radiation to reach Earth’s surface, leading to increased incidence of skin cancer.

During a recent oceanographic expedition off San Diego, graduate student researchers discovered convincing evidence of a deep-sea site where methane is likely seeping out of the seafloor, the first such finding off San Diego County.

First time measurements of large-scale methane emissions have been taken from the extensive Arctic permafrost landscapes.
