As the CFCs slowly degrade over the coming decades, so too should the volcano’s ozone-destroying power. However, new research shows that the volcanic risk to the ozone layer will persist for decades longer than previously believed.

Late spring and early summer is when the air quality is generally good across most of the United States. But newly published research details how a common springtime weather pattern and pollution transported from Asia often conspire to create unhealthy ozone levels for the desert southwest. The new study adds to a growing body of work that explores how ozone can occasionally push some areas of the desert southwest above federal air quality standards.

A deep sea fishing rod is probably not the first tool that comes to mind when thinking about how to study air pollution in a remote inland desert, but it’s the heart of a new system that has given scientists a minute-by-minute look at how quickly the sun can convert oil and gas emissions to harmful ground-level ozone.

The first peer-reviewed study to directly quantify how emissions from oil and gas activities influence summertime ozone pollution in the Colorado Front Range confirms that chemical vapors from oil and gas activities are a significant contributor to the region’s chronic ozone problem.

By Larry O’Hanlon Something strange has happened to the atmospheric concentration of a newly discovered, human-made, ozone-destroying gas: it has suddenly dropped and nobody knows why. The gas, HCFC-133a, is a type of hydrochlorofluorocarbon, ozone-destroying compounds used in some industrial processes, including the manufacturing of refrigerants. The use of HCFCs, which are also powerful greenhouse gases, is restricted under the Montreal Protocol. A study last year first identified HCFC-133a as …
