Many years ago a bunch of countries decided to take action to stop damaging the ozone layer in the hopes that it will eventually recover. It’s great to see that the efforts of working together to protect the environment of come to fruition and let’s hope we see efforts like this directed towards climate change.
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.
