Chemicals that eased one environmental problem may worsen another

Chemicals that eased one environmental problem may worsen another

Chemicals that helped solve a global environmental crisis in the 1990s -- the hole in Earth's protective ozone layer -- may be making another problem -- acid rain -- worse, scientists are reporting. A new study analyzes the effect of chemicals that replaced the ozone-destroying chlorofluorocarbons once used in aerosol spray cans, air conditioners, refrigerators, and other products.
Emissions of Potent Greenhouse Gas Increase Despite Reduction Efforts

Emissions of Potent Greenhouse Gas Increase Despite Reduction Efforts

Despite a decade of efforts worldwide to curb its release into the atmosphere, scientists have measured increased emissions of a greenhouse gas that is thousands of times more efficient at trapping heat than carbon dioxide and persists in the atmosphere for nearly 300 years.
Ozone hole healing could cause further climate warming

Ozone hole healing could cause further climate warming

The hole in the ozone layer is now steadily closing, but its repair could actually increase warming in the southern hemisphere, according to scientists.
Springtime ozone increases above western North America linked to emissions from abroad

Springtime ozone increases above western North America linked to emissions from abroad

Springtime ozone levels above western North America are rising primarily due to air flowing eastward from the Pacific Ocean, a trend that is largest when the air originates in Asia.
Ethanol-powered vehicles generate more ozone than gas-powered ones

Ethanol-powered vehicles generate more ozone than gas-powered ones

Vehicles running on ethanol will generate higher concentrations of ozone than those using gasoline, especially in the winter, researchers have found. That could create new health concerns in areas where ozone hasn't been a significant problem before.
