In their paper, they estimated that if CFC use was banned immediately, ozone loss would go on for years. If CFC production continued, however, ozone loss would be even greater. “When we realized there ...

While CFC-112a's appearance is assumed to result from the byproduct of a different industrial reaction, scientists can only speculate as to where CFC-13 is originating from.

A new study shows a shocking spike in emissions for an ozone-depleting chemical banned more than 20 years ago. The culprit who is generating this pollutant is still unknown and at large.

Ozone pollution isn’t just a summer story anymore. In parts of northern China, high ozone levels are now appearing during winter—an alarming twist that defies decades of air quality science. This ...

Emissions of a banned, ozone-depleting chemical are on the rise, a group of scientists reported Wednesday, suggesting someone may be secretly manufacturing the pollutant in violation of an internat… ...

WASHINGTON – Cool your home, warm the planet. When more than two dozen countries undertook in 1989 to fix the ozone hole over Antarctica, they began replacing chlorofluorocarbons in ...

Despite CFC ban, ozone hole won't heal until 2070, ... CFCs deplete ozone because they can bind to oxygen molecules in several chemical reactions, breaking ozone down into regular oxygen molecules.

There the sun's harsh rays split the CFCs apart, triggering chemical reactions that destroyed ozone molecules. As the ozone shield weakened, more of the sun's dangerous UV rays would reach the ...

In his forthcoming book, 'New Theories and Predictions on the Ozone Hole and Climate Change,' Professor Lu quantifies the contributions of the cosmic-ray-driven electron-induced-reaction mechanism ...

The ozone layer is healing, ... creating the ideal conditions for ozone-destroying chemical reactions that begin as the Sun returns. ... CFC-11 is not the only rogue ODS, ...

A three decades old international treaty to phase out chemicals that deplete the ozone layer protecting our planet from harmful solar radiation is paying off. Thanks to the 1987 Montreal Protocol ...

The language is dry and academic, as is appropriate for the abstract of a scientific paper in the prestigious journal Nature. The research described in the short paper, however, fell like a scientific ...
