The ozone layer is not healing as quickly as expected, leading to higher levels of surface ultraviolet (UV) radiation in recent years, according to a study.
Despite projections that the ozone layer would fully recover by mid-century, researchers found rising UV radiation levels in the tropics and northern mid-latitudes after 2010, posing risks to human health and the environment.
"Our analysis shows disturbed ozone levels and enhanced surface UV radiation for more than a decade after 2010," said study lead author Yan Xia of Beijing Normal University, China.
