Age: The hole in the ozone layer is healing, and well on track to further recovery over the next few decades, due to concerted international action to reduce ozone depleting gases, according to a new assessment by 300 scientists. The Assessment for Decision-Makers is a summary document of the Scientific Assessment of Ozone Depletion 2014, published by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO). Since the early 1980s scientists involved in this...

Our Ozone Hole is Still Shrinking, Says NASA

Nature World: There's a big hole in our ozone right over the Antarctic right now, and it's slightly bigger than last year. However, according to NASA data, this hole is still significantly smaller than it was a decade ago and is likely going to keep shrinking. The ozone layer is an exceptionally important part of the Earth's atmosphere that shields life from potentially harmful ultraviolet radiation that can cause skin cancer and damage plants. Not too long ago, it was discovered that there are a number of...

Climate Central: The ozone hole is a gash in the stratosphere, like a festering wound high above the earth's surface. Scientists first diagnosed the problem in the mid-1980s and recommended a course of action to treat the problem. And today, NASA announced that recovery has continued, though slightly slower this year compared to years past.

Hill: The Environmental Protection Agency (EPA) sent potential changes to the standard for ground-level ozone to the White House Office of Management and Budget onn Wednesday. The EPA has not said whether it will try to lower the Bush administrations maximum limit of 75 parts per billion; it could simply reaffirm that standard. The EPAs staff and its scientific advisers have asked the agency to reduce to 60-70 parts per billion the allowable concentration of ozone, the main component of smog. The White...

Hooray for the Earth: International action has helped the ozone layer
2014-09-12 23:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Post Gazette: Bad news about the health of planet Earth has kept up a steady drumbeat lately just this week the National Audubon Society released a report on the effect of climate change on birds concluding that as many as 314 out of 588 North American species will lose more than half of their climatic range by 2080. Of those, 126 are considered climate endangered. Yet amid the warning drums, a rallying trumpet of hope has sounded, not on climate change directly but a related problem. According to a U.N. scientific...
