Gaping hole in ozone layer shows recovery, scientists say

Christian Science Monitor: The troublesome tear in Earth's protective blanket is getting stitched up. A gaping hole in the ozone layer has been opening up over Antarctica each spring for decades. And now there are signs that the slow process of healing has begun, according to a study published Thursday in the journal Science. Scientists credit this progress to the 1987 Montreal Protocol, an international treaty that phased out chemicals that eat away at the ozone layer, which shields our planet from deadly levels of...

Ozone hole not so holey anymore

Grist: Heres something we dont get to say very often here at Grist dot org: Good news, humans! Remember the hole in the ozone layer? Well, three decades after countries started banning the chemicals destroying it, the ozone layer is on the mend, according to a study published Thursday in the journal Science. While a full recovery isnt expected until mid-century, researchers found that the seasonal hole in the ozone layer over Antarctica is shrinking. The hole, which was discovered in 1984, was caused...

Bright spot: Antarctica's ozone hole is starting to heal
2016-06-30 13:29:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: Antarctica's ozone hole finally is starting to heal, a new study finds. In a triumph of international cooperation over a man-made environmental problem, research from the United States and the United Kingdom shows that the September-October ozone hole is getting smaller and forming later in the year. And the study in Thursday's journal Science also shows other indications that the ozone layer is improving after it was being eaten away by chemicals in aerosols and refrigerants. Ozone is a combination...

Ozone hole nears record-breaking size again
2015-11-12 16:57:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: The hole in the ozone layer over Antarctica is nearing record-breaking size again, scientists say. In fact, new observations show that the infamous "ozone hole" is currently larger than the entire continent of North America. Researchers at the German Aerospace Center are using Earth-observing satellites to monitor the protective ozone layer and recently reported that a large, nearly circular hole over Antarctica extends over an area measuring 26 million square km (10 million square miles). Losing...
This Years Ozone Hole is the Fourth-Largest on Record

Climate Central: This year the hole formed later and lasted two weeks longer than usual, leading to almost 100 percent ozone depletion. While ozone-depleting chemicals are still playing a role, natural factors, such as stratospheric circulation, also helped drive this years widespread thinning. During September we typically see a rapid ozone decline, ending with about 95 percent depletion in that layer by October 1, Bryan Johnson, a researcher at the Earth System Research Laboratory, said in a press release....
