WASHINGTON, Feb. 22 /PRNewswire-USNewswire/ -- The Alliance for Responsible Atmospheric Policy (Alliance), an industry coalition, today commended the sentencing of a Florida man and a Florida corporation on charges related to smuggling 418,654 kilograms of hydrochlorofluorocarbon-22 (HCFC) refrigerants with a market value of over $3.9 million. James Garrido was sentenced to 30 months imprisonment and Kroy Corporation was sentenced to five years of probation. They must jointly pay $40,000...

The hole in the ozone layer is now steadily closing, but its repair could actually increase warming in the southern hemisphere, according to scientists at the University of Leeds. The Antarctic ozone hole was once regarded as one of the biggest environmental threats, but the discovery of a previously undiscovered feedback shows that it has instead helped to shield this region from carbon-induced warming over the past two decades. High-speed winds in the area beneath the hole have led to the...

Pollution from Asia is causing ozone levels to rise above the western United States, an increase that could make it more difficult for the U.S. to meet Clean Air Act standards for ozone pollution at ground level, according to an international study published on Wednesday. The study, published in the journal Nature, analyzed large sets of ozone data captured since 1984. It focused primarily on data for ozone in springtime above western North America at an altitude of between two and five...

Researchers in Freiburg have developed a highly-sensitive, miniaturized mobile ozone sensor which can be used not only in air, but also in water and in the vicinity of explosive gases. The Fraunhofer Institute for Applied Solid State Physics IAF in Freiburg is developing improved chemical sensors that are not prohibitively expensive. One particularly important area of application involves the regular measurement of ozone content in air and other media. This gas is a powerful oxidizing agent...

There is more to the snowflake than its ability to delight schoolchildren and snarl traffic. The structure of the frosty flakes also fascinate ice chemists like Purdue University's Travis Knepp, a doctoral candidate in analytical chemistry who studies the basics of snowflake structure to gain more insight into the dynamics of ground-level, or "tropospheric," ozone depletion in the Arctic. "A lot of chemistry occurs on ice surfaces," Knepp said. "By better understanding the physical structure...

Marco Tedesco Says Record Low Resulted From Simultaneous Positive Phases for Two Climate Drivers The 30-year record low in Antarctic snowmelt that occurred during the 2008-09 austral summer was likely due to concurrent strong positive phases for two main climate drivers, ENSO (El Niño - Southern Oscillation) and SAM (Southern Hemisphere Annular Mode), according to Dr. Marco Tedesco, Assistant Professor of Earth & Atmospheric Sciences at The City College of New...

A major scientific report released on Tuesday showed that rapid ice loss in West Antarctica will likely contribute heavily to a projected sea level rise of up to 4.5 feet by 2100, AFP reported. For years scientists believed that most of Antarctica's continent-sized ice sheet was highly resistant to global warming, and that the more vulnerable West Antarctic ice block would remain intact for thousands of years to come. But according to the review by more than 100 experts on the Scientific...

'Antarctic Climate Change and the Environment' The first comprehensive review of the state of Antarctica's climate and its relationship to the global climate system is published this week (Tuesday 1 December) by the Scientific Committee on Antarctic Research (SCAR). The review - Antarctic Climate Change and the Environment "“ presents the latest research from the icy continent, identifies areas for future scientific research, and addresses the urgent questions that policy makers have...

PORT GHALIB, Egypt, Nov. 9 /PRNewswire-USNewswire/ -- Yesterday, two small islands fighting rising seas and growing storm surges driven by climate change were joined by a growing army of nations to support their battle to phase down super greenhouse gases. The weapon of choice for the Federated States of Micronesia and Mauritius is the Montreal Protocol ozone treaty. Their target is a group of super greenhouse gases known as hydrofluorocarbons, or HFCs. The support from the coalition of...

WASHINGTON, Oct. 19 /PRNewswire-USNewswire/ -- BASF Corporation has agreed, under a Clean Air Act settlement filed today in federal court in Beaumont, Texas, to reduce the use of refrigerant chemicals that destroy the earth's stratospheric ozone layer, the Justice Department and the U.S. Environmental Protection Agency (EPA) announced. The company will spend more than an estimated $250,000 to retrofit one refrigeration unit that currently uses such chemicals, replacing them with...
