A new study led by Columbia University researchers has found that the closing of the ozone hole, which is projected to occur sometime in the second half of the 21st century, may significantly affect climate change in the Southern Hemisphere, and therefore, the global climate. The study appears in the June 13th issue of Science.

Climate models overheat Antarctica

Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise.

Seafloor cores show tight bond between dust and past climates

Each year, long-distance winds drop up to 900 million tons of dust from deserts and other parts of the land into the oceans. Scientists suspect this phenomenon connects to global climate—but exactly how, remains a question.

Mission critical for carbon management

Integrating science and public policy with the needs of consumers and the global economy is critical if we have any chance of reducing the effects of carbon on the climate, say scientists at the 2008 Annual Meeting of the American Association for the Advancement of Science (AAAS).

Cloud chemistry concocts aerosols

Aerosols influence global climate by scattering incoming solar radiation, causing a cooling effect. Much of this effect results from organic aerosols, which are classified as “primary” or “secondary.”

New insights into the role of Southern Ocean for global climate

In the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of the surface waters, which can affect the global carbon dioxide cycle.
