Hot weather in Europe exacerbating ozone pollution
2013-08-18 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Malta Independent: Unusually high temperatures this summer may be contributing to poor air quality in many European cities, the European Environment Agency (EEA) said this week, and thresholds to protect health from ground-level ozone have been exceeded across Europe in recent weeks, according to preliminary data reported to the EEA. Ozone pollution has serious effects on health, especially for older people and children, or those with asthma and other respiratory problems. Reducing ozone pollution in the air depends...

Slight Global Warming May Come From Ozone Winds
2013-08-09 16:18:00| Climate Ark Climate Change & Global Warming Newsfeed
redOrbit: Laypeople tend to mix up the ozone hole and global warming. The popular belief is that the hole is a major cause of the worlds increasing average temperature. On the other hand, scientists have long attributed the ozone shortage in the hole to a small cooling trend. A new computer model study, led by the Lamont-Doherty Earth Observatory, suggests that there might be a slight warming influence from the ozone hole. The influence is due to the holes effect on winds, however, not temperatures. The...

Hole in the Ozone May Have a Cooling Effect After All, Study Shows
2013-08-08 22:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Contrary to prevailing scientific beliefs, the hole found in the ozone layer may have a slight warming influence -- not because of its effect on temperatures, but due to its influence on wind. Published in the journal Geophysical Research Letters, a new study suggests that the ozone hole is causing a shift in wind patterns that pushes clouds farther toward the South Pole. As this happens, the amount of radiation the clouds reflect is reduced, possibly causing a small amount of warming rather than...
U.S. appeals court partially upholds ozone pollution rule

Reuters: A federal appeals court on Tuesday partially upheld U.S. Environmental Protection Agency regulations issued by former President George W. Bush's administration that set standards for ozone pollution. The U.S. Court of Appeals for the District of Columbia Circuit sent a portion of the regulations back to the agency for further consideration but left the entirety of the rule in place while the revisions are carried out. Ozone pollution forms when air pollutants react with sunlight and has been...

High Ozone levels during Heat Wave Make Air Pollution Worse
2013-07-22 10:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: High temperatures make air pollution worse. A new study has found that during heat waves, plants reduce their ozone absorption which lead to high levels of the gas remaining in the environment. Ozone is a gas that exists both at stratosphere and troposphere and can be beneficial or toxic depending on its location. When close to the ground, the gas is known to increase asthma risk in children and damage crops and tress. Ozone is the major ingredient in the urban smog. Like Us on Facebook Ozone...
