Researchers at the University of Pittsburgh have developed a fluorescent molecular probe that can selectively detect ozone—in preference to other reactive oxygen species—in both atmospheric and biological samples. Ground-level ozone exposure is a growing global health problem, especially in urban areas. Garner, Claudette M.

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

Researchers in France have found that ozone depletion above Antarctica has significantly reduced the Southern Ocean’s ability to absorb atmospheric CO 2 and has also accelerated acidification of southern polar waters, despite lesser CO 2 uptake. This corresponds to a relative reduction of nearly 10% of the global oceanic carbon uptake.

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C °F) by 2050, as well as improving human health and agriculture.

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.

This is slightly higher than the 2009 AGGI, which was 1.27—i.e., It also includes several chemicals known to deplete Earth’s protective ozone layer, which are also active as greenhouse gases. Methane measured 1794 ppb in 2009, and 1714 ppb in 1990. Started in 2004, the AGGI reached 1.29 in 2010—i.e., —i.e.,
