Ground-level ozone is an air pollutant that harms humans and plants. Both climate and weather play a major role in ozone damage to plants. Researchers at the University of Gothenburg, Sweden, have now shown that climate change has the potential to significantly increase the risk of ozone damage to plants in northern and central Europe by the end of this century. "The increased risk of ozone damage to vegetation is mainly due to rising ozone concentrations and higher temperatures in the...

Australian research institute Commonwealth Scientific and Industrial Research Organization (CSIRO) launched a new website on Monday that allows Internet users to monitor greenhouse gas emissions. The site was developed so people can see how climate-warming gases have increased as a result of human activities. "The measurements testify to a steady rise in carbon dioxide concentrations in the Earth's atmosphere, mainly caused by the burning of fossil fuels and deforestation," CSIRO scientist...

Subsidies for Super Greenhouse Gas Manufacture Must be Eliminated WASHINGTON, May 24, 2011 /PRNewswire-USNewswire/ -- The Environmental Investigation Agency (EIA) is calling for an end to the expensive UN program that pays over a billion dollars a year to capture and destroy the super greenhouse gas HFC-23. On the eve of an expected decision by the UN's Clean Development Mechanism on the HFC-23 methodology, EIA is calling for the methodology to be retired and the current contracts for...

The research aircraft Polar 5 of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association returned to Bremerhaven from a six-week expedition in the high Arctic on May 6. Joint flights with aircraft of the European and American space agencies (ESA and NASA) were a novelty in sea ice research. Simultaneous measurements with a large number of sensors on three planes underneath the CryoSat-2 satellite led to unique data records. Furthermore, the international team...

In a new study published in Science magazine, US researchers on Thursday said the hole in the ozone layer over Antarctica is a major driver of climate change and rain increases in the southern hemisphere over the last 50 years. The stratospheric ozone layer, which protects the Earth from harmful solar ultra-violet radiation, has thinned dramatically over the past half-century. The depletion of ozone has shifted the Southern Hemisphere's climate so that dry areas in the subtropics now see 10...

First time that ozone depletion is shown to impact the entire circulation of the southern hemisphere In a study to be published in the April 21st issue of Science magazine, researchers at Columbia University's School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation of the Southern Hemisphere all the way to the equator. While previous work has shown that the ozone hole is changing the...

MINNEAPOLIS, April 13, 2011 /PRNewswire/ -- Cargill will be a financial and exclusive marketing partner for the tradable emission credits generated by San Francisco-based EOS Climate, a company which uses market-based incentives to prevent emissions of harmful greenhouse gases (GHGs) associated with older refrigerators and cooling systems. These systems typically contain chlorofluorocarbons (CFCs), chemicals which are extremely harmful to the ozone layer, and have been phased out of...

Storing fruits and vegetables in ozone-enriched environments reduces spoilage explains a scientist at the Society for General Microbiology's Spring Conference in Harrogate. Dr Ian Singleton explains how ozone treatment could be a safe, effective replacement for pesticides as it leaves no residue on foods. It is estimated that up to 30% of fresh produce can be lost due to microbial spoilage. Dr Singleton from Newcastle University explains that low levels of gaseous ozone are able to prevent...

Over the past few days ozone-depleted air masses extended from the north pole to southern Scandinavia leading to higher than normal levels of ultraviolet (UV) radiation during sunny days in southern Finland. These air masses will move east over the next few days, covering parts of Russia and perhaps extend as far south as the Chinese/Russian border. Such excursions of ozone-depleted air may also occur over Central Europe and could reach as far south as the Mediterranean. On an international...

In the spring of 2011, the ozone layer that protects us from harmful levels of ultraviolet rays has shown a record loss in the Arctic region, according to the U.N. weather agency. The continued presence of ozone-depleting substances in the atmosphere coupled with a very cold winter in the stratosphere is to blame. Although an international agreement from 1987 called the Montreal Protocol has successfully reduced the production and consumption of these ozone destroying chemicals, the long...
