![]() Earth’s protective ozone layer is beginning to recover, largely because of the phaseout since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. scientific panel reported last week in a rare piece of good news about the health of the planet.
Scientists said the development demonstrates that when the world comes together, it can counteract a brewing ecological crisis. For the first time in 35 years, scientists were able to confirm a statistically significant and sustained increase in stratospheric ozone, which shields the planet from solar radiation that causes skin cancer, crop damage and other problems. From 2000 to 2013, ozone levels climbed 4 percent in the key mid-northern latitudes at about 30 miles up, said NASA scientist Paul A. Newman. He co-chaired the every-four-years ozone assessment by 300 scientists, released at the United Nations.
