Arctic ozone loss at record level

By Richard Black
Environment correspondent, BBC News

Ozone loss over the Arctic this year was so severe that for the first time it could be called an “ozone hole” like the Antarctic one, scientists report.

About 20km (13 miles) above the ground, 80% of the ozone was lost, they say.

Early data on the scale of Arctic ozone destruction were released in April, but the Nature paper is the first that has fully analysed the data.

“But over the last few decades, the winters that are cold have been getting colder.

“So given that trend and the high variability, we’d anticipate that we’ll have other cold ones, and if that happens while chlorine levels are high, we’d anticipate that we’d have severe ozone loss.”

Ozone-destroying chemicals originate in substances such as chlorofluorocarbons (CFCs) that came into use late last century in appliances including refrigerators and fire extinguishers.

Their destructive effects were first documented in the Antarctic, which now sees severe ozone depletion in each of its winters.

The ozone layer blocks ultraviolet-B rays from the Sun, which can cause skin cancer and other medical conditions.
