Ozone Losses May Be Speeding Up at Higher Latitudes, According to Study
May 28 — New findings by University of Colorado at Boulder researchers indicate ozone losses due to the breakdown of chlorofluorocarbons, or CFCs, occur much faster than previously believed at higher latitudes roughly 10 miles above Earth. More

Uncertainty in West African Climate Models Addressed
May 28 — Plans to meet the outcome of global climate change are underway worldwide, but nowhere is that planning more difficult than in West Africa where the climate has some of the largest signals of change and the climate models have the greatest level of uncertainty, according to Penn State meteorologists.

Huge Antarctic Icebergs Break Away Near NSF Research Hub
May 23 — Two new and very large icebergs broke away from the Ross Ice Shelf in Antarctica earlier this month in a natural "calving" process that returned the edge of the shelf to its pre-exploration position of the early 1900's, researchers say. (National Science Foundation release) More

Human Activity Raises Level of Sulfur Gas that Affects Ozone Layer, Researchers Say
May 16 — Human-produced carbonyl sulfide has attracted attention as a possible source of increased levels of sulfate particles, or aerosols, in the atmosphere, which have been linked to depletion of the ozone layer. (American Geophysical Union release) More

End of 'Free Ride' on Ecosystem CO2 Absorption
May 15 — According to a new study, the world may soon see the end of the "free ride," in which carbon absorption by natural ecosystems ameliorates the rise in atmospheric CO2 due to fossil fuel burning and loss of forest. (Duke University release) More

In Midst of Drought, Scientists Hunt for Water Vapor
May 8 — Over 100 researchers will profile the water vapor that feeds heavy rain and thunderstorms across Kansas, Oklahoma, and Texas as part of the large, complex International H20 Project. (University Corporation for Atmospheric Research release) More

Scripps Researchers Use High-Tech Imagery for New Insights into Breaking Wave Dynamics
May 1 — To scientists who study interactions between the air and the sea, breaking waves represent one of the most vital air-sea exchange mechanisms. (Scripps Institution of Oceanography at the University of California, San Diego release) More
