Antarctic Ozone Hole is the Smallest on Record Since Its Discovery [Video]
Abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion in September and October, resulting in the smallest ozone hole observed since…
Scientists Discover a Hidden Threat to Corn
Like atmospheric methane and carbon dioxide, ground-level ozone is on the rise. But ozone, a noxious chemical byproduct of fossil fuel combustion, has received relatively…
NASA Study Provides First Direct Proof of Ozone Hole Recovery Due to Chemicals Ban
Using measurements from NASA’s Aura satellite, scientists studied chlorine within the Antarctic ozone hole over the last several years, watching as the amount slowly decreased….
Scientists Monitor Positive Signs of Recovery of the Earth’s Stratospheric Ozone Layer
Each year, ozone-depleting compounds in the upper atmosphere destroy the protective ozone layer, and in particular above Antarctica. The ozone layer acts as Earth’s sunscreen…
NASA Scientists Track Ozone Pollution by Monitoring Key Ingredients
New NASA-funded research has devised a way to use satellite measurements to track ozone formation among three different sets of conditions. Ozone pollution near Earth’s…
2017 Ozone Hole is the Smallest Since 1988
This year’s ozone hole was similar in area to the hole in 1988, about 1 million miles smaller than in 2016. Although scientists predict the…
Antarctic Ozone Layer Shows Signs of Healing
New research details the “first fingerprints of healing” of the Antarctic ozone layer. Scientists found that the September ozone hole has shrunk by more than…
2015 Antarctic Ozone Hole Larger Than Recent Years
Scientists from NASA and the National Oceanic and Atmospheric Administration reveal that the 2015 Antarctic ozone hole area was larger and formed later than in…
New NASA Study Shows That Hydrofluorocarbons Contribute to Ozone Depletion
According to new research from NASA, chemical coolants known as hydrofluorocarbons that are found in refrigerators and in home and automobile air conditioners, contribute to…
2014 Antarctic Ozone Hole Comparable to Previous Years
Scientists from NASA and the National Oceanic and Atmospheric Administration reveal that the overall 2014 ozone hole is smaller than the large holes of the…
Worldwide Action to Phase Out Ozone-Depleting Substances Yields Significant Gains
This short video and new assessment packet reveals the remarkable success of the worldwide action to phase out ozone-depleting substances, reporting that the ozone layer…
Earth’s Atmosphere Contains an Unexpectedly Large Amount of Ozone-Depleting Compound
A newly published study from NASA shows that Earth’s atmosphere contains an unexpectedly large amount of Carbon tetrachloride (CCl4), leaving researchers to believe that there…
Research Reveals New Man-Made Ozone-Depleting Gases in the Atmosphere
New research from scientists at the University of East Anglia reveals four new man-made gases in the atmosphere that are contributing to the destruction of…
Study Links Levels of Air Pollution and Ozone to Cardiac Arrest
Based on a massive data set unique to Houston, a newly published study from scientists at Rice University has found a direct correlation between out-of-hospital…
Fluctuations in Weather Patterns Help Decrease the Antarctic Ozone Hole
Data from NASA and NOAA satellites show that the average area covered by the Antarctic ozone hole this year was the second smallest in the…
Intercontinental Crop Losses Caused by Ozone
Researchers at the University of Leeds, in collaboration with the University of York, published a new study showing the extent of the Northern Hemisphere’s intercontinental…
