Ozone layer recovery delayed, surface UV radiation continues to rise, finds 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.

“Continuous monitoring of ozone and UV radiation levels is important to better understand why ozone recovery is delayed and whether this trend will continue,” Xia warned. “Policymakers and the public should be aware of and prepare for the harmful effects of enhanced surface UV radiation on the environment, agriculture, and public health.”

“The slower recovery of stratospheric ozone is largely unexpected.”
