  • Greenhouse Gas Concentrations Reach New Record

    The amount of greenhouse gases in the atmosphere reached a new record high in 2011, according to the World Meteorological Organization. Between 1990 and 2011 there was a 30% increase in radiative forcing – the warming effect on our climate – because of carbon dioxide (CO2) and other heat-trapping long-lived gases. Since the start of the industrial era in 1750, about 375 billion tonnes ...

  • Ozone layer recovery may be delayed by greenhouse gas emissions

    The ozone layer in the stratosphere protects life on Earth from harmful radiation, but emissions from human activity have damaged this defence. A new study suggests that ozone recovery could be delayed, or even postponed indefinitely for some regions, by the impact of increasing amounts of greenhouse gases (GHGs) in the atmosphere. Although ozone at ground level is hazardous to health, ozone in ...

  • Space watch on air quality

    Sensitive sensors located in space are being drafted to help scientists monitor the state of the quality of the Earth’s air. With air pollution becoming one of the world's biggest dangers to society's health and an economic drain on some nations, current and up- to-date information on air pollution levels and their movement are vital to researchers tackling this problem. The ESA Earth Observation ...

  • Hourly Ground-Level Ozone Forecasts Now Coast to Coast

    WASHINGTON, DC, October 3, 2007 (ENS) - Ground-level ozone forecasts, for years a key predictor of air quality in major U.S. cities, are now posted and mapped online on an hourly basis throughout the lower 48 United States. Ground-level ozone is a main ingredient of urban smog, that brown cloud hanging over the skylines of urban areas. 'Poor air quality is a silent ...

  • Several California Cities Rank Highest on the American Lung Association’s List of Most Ozone Polluted Cities

    Bonded activated carbon filters from UltraViolet Devices (UVDI) provide solutions for ozone removal in California and cities nationwide. The American Lung Association recently released their annual report, State of the Air 2010.  The report reveals ozone and particulate pollution levels found at monitoring sites across the country. The California cities of Los Angeles, Long Beach and ...

  • Southern ozone hole slightly smaller this year

    Warm air at high altitudes this September and October helped shrink the man-made ozone hole near the South Pole ever so slightly, scientists say. The hole is an area in the atmosphere with low ozone concentrations. It is normally is at its biggest this time of year. NASA says on average it covered 8.1 million square miles this season. That's 6 percent smaller than the average since 1990. The ...

  • Ocean acidification and GHGs hit record levels

    The World Meteorological Organisation (WMO) reports that the amounts of atmospheric greenhouse gases reached a new high in 2013, driven by rapidly rising levels of carbon dioxide. The news is consistent with trends in fossil fuel consumption. But what comes as more of a surprise is the WMO’s revelation that the current rate of ocean acidification, which greenhouse gases (GHGs) help to ...

  • Ozone Layer on Track to Recovery: Success Story Should Encourage Action on Climate

    The Earth's protective ozone layer is well on track to recovery in the next few decades thanks to concerted international action against ozone depleting substances, according to a new assessment by 300 scientists. The Assessment for Decision-Makers, a summary document of the Scientific Assessment of Ozone Depletion 2014, is being published by the United Nations Environment ...

  • US settles with Costco to cut ozone-depleting and greenhouse gas refrigerant emissions nationwide

    Costco Wholesale Corporation, the nation’s second largest retailer, has agreed to cut its emissions of ozone-depleting and greenhouse gas chemicals from refrigeration equipment at more than half of its stores nationwide. In the settlement announced today by the U.S. Environmental Protection Agency (EPA) and Department of Justice (DOJ), Costco will pay $335,000 in penalties for federal Clean ...

  • Avoiding harmful ozone pollution this summer

    High summer temperatures combined with air pollution can cause ground-level ozone to form, which has serious effects on health, especially for older people or children, or those with asthma and other breathing problems. The European Environment Agency (EEA) presents some useful information on protecting your health from ground-level ozone this summer. To date, the highest concentrations ...

  • Hot summer weather exacerbating ozone pollution

    Unusually high temperatures this summer may be contributing to poor air quality in many European cities. Thresholds to protect health from ground-level ozone have been exceeded across Europe in recent weeks, according to preliminary data reported to the European Environment Agency (EEA). Ozone pollution has serious effects on health, especially for older people and children, or those with ...

  • Tracking down the menace in Mexico City smog

    A new report by scientists who are part of the international MILAGRO Campaign indicates that some of the most harmful air pollution in Mexico City may not come from motor vehicles but instead originates with industrial sources – and that the culprit may be garbage incineration. The MILAGRO Campaign (Megacity Initiative: Local and Global Research Observations) monitored air quality in the Mexico ...
