Antarctic ozone hole among the smallest recorded in 20 years
Warmer temperatures in the atmosphere above Antarctica this year likely contributed to the smaller ozone hole.
Big summer storms deplete ozone layer, new study says
Thunderstorm clouds over the U.S. could shoot water vapor into the stratosphere where it could react and contribute to the loss of protective ozone.
Do thunderstorms make ozone? Researchers to map the clouds for the answer
Scientists will fly through storms to collect data on pollutants and then fly through the same air mass the next day to determine changes.
Rocks release ozone gas before earthquakes
Lab experiments that crushed rocks that often grind together in earthquakes showed that large amounts of ozone are emitted by the crushing.
Antarctic ozone hole nearly the size of North America
The hole is the partial or complete depletion of ozone between 8.7 to 13.7 miles above Earth’s surface.
Gamma rays could end life on Earth
Gamma ray bursts from the sun could be contributing to the depletion of the Earth’s ozone layer.
Arctic ozone hole detected for the first time
Cold temperatures this year and still-circulating pollutants contributed to the development of the new ozone hole.
Bad air day: Obama’s smog mistake
The administration drank the conservative Kool-Aid and agreed that tightening ozone emission rules would have cost billions and hurt the economy. But clean air is popular politically, and the EPA’s own studies show that a tighter standard could have created $17 billion in economic benefits.
How dead skin may actually be a good thing
Oil associated with dead skin in dust helps remove the pollutant ozone.
