A new discovery by scientists at the Universities of East Anglia and Frankfurt could make it possible in future to identify the source of banned CFCs that are probably still being released into the atmosphere. Using mass spectrometers, the researchers analyzed air samples collected in the stratosphere by balloons belonging to the French space agency, the Centre National d'Etudes Spatiales (CNES). They discovered the largest chlorine isotope enrichment ever found in nature. CFCs were banned in...

A U.N. board that oversees a $2.7 billion market intended to cut heat-trapping gases has agreed to take steps that could lead to reining in what European and U.S. environmentalists call a gigantic scam. The executive board of the U.N.'s Clean Development Mechanism said that five chemical plants in China do not qualify for funding. The "CDM" credits have been widely used in the carbon trading markets of the European Union (EU), Japan and other nations that signed the 1997 Kyoto Protocol that...

On July 6 this summer, Virginia's Department of Environmental Quality issued the region's first "unhealthy" air alert since 2008.The culprit? "Bad" ozone and other air pollution that had combined to produce an abnormally high reading of 119 parts per billion in Suffolk and 70-80 parts per billion in other parts of southeastern Virginia. That compares to the natural concentration of ozone of about 10 parts per billion that was the norm more than a century ago.Ozone spikes are part of a pattern...

KIT Scientists Disprove Doubts in Ozone Hole Chemistry For the first time, KIT scientists have successfully measured in the ozone layer the chlorine compound ClOOCl which plays an important role in stratospheric ozone depletion. The doubts in the established models of polar ozone chemistry expressed by American researchers based on laboratory measurements are disproved by these new atmospheric observations. The established role played by chlorine compounds in atmospheric ozone chemistry is in...

Although global grain production must double by 2050 to address rising population and demand, new data from the University of Illinois suggests crop yields will suffer unless new approaches to adapt crop plants to climate change are adopted. Improved agronomic traits responsible for the remarkable increases in yield accomplished during the past 50 years have reached their ceiling for some of the world's most important crops. "Global change is happening so quickly that its impact on...

Human-driven changes in the earth's atmospheric composition are likely to alter plant diseases of the future. Researchers predict carbon dioxide will reach levels double those of the preindustrial era by the year 2050, complicating agriculture's need to produce enough food for a rapidly growing population. University of Illinois researchers are studying the impact of elevated carbon dioxide, elevated ozone and higher atmospheric temperatures on plant diseases that could challenge crops in...
