| SCIENTISTS FIND OZONE-DESTROYING MOLECULE |
| For years, scientists theorized that a molecule called ClOOCl in the stratosphere played a key role in destroying ozone. Now, using measurements from a NASA aircraft laboratory flying over the Arctic, Harvard scientist Rick Stimpfle and colleagues observed the molecule for the first time. They report their discovery in the Journal of Geophysical Research-Atmospheres, published by the American Geophysical Union. |

| EARTH'S OZONE LAYER BEGINS REPAIRING ITSELF |
| The rate of ozone destruction in the upper atmosphere is slowing, suggesting for the first time the global ban on the production and release of damaging industrial gases is having an effect. |

| GLOBAL WARMING A 'WEAPON OF MASS DESTRUCTION' |
| Global climate change induced by humans is a 'weapon of mass destruction' at least as dangerous as nuclear, chemical or biological arms, a leading climate scientist has said. |

| NEW STUDY SHEDS LIGHT ON FROG MALFORMATIONS |
| The emergence of mutant frogs with extra arms and legs may smack of a low-budget sci-fi script. But it is a reality, and a new study provides more evidence that ultraviolet radiation could be responsible. The findings are reported in three consecutive papers in the July 1 print issue of Environmental Science & Technology, a peer-reviewed journal of the American Chemical Society, the world's largest scientific society. |

| 2001 OZONE HOLE ABOUT THE SAME SIZE AS PAST THREE YEARS |
| Satellite data show the area of this year's Antarctic ozone hole peaked at about 26 million square kilometers -- roughly the size of North America -- making the hole similar in size to those of the past three years, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). Researchers have observed a leveling-off of the hole size and predict a slow recovery. |
