Arctic Ozone Levels in Never-Before-Seen Plunge (BBC)

The ozone layer has seen unprecedented damage in the Arctic this winter due to cold weather in the upper atmosphere. By the end of March, 40% of the ozone in the stratosphere had been destroyed, against a previous record of 30%. The ozone layer protects against skin cancer, but the gas is destroyed by reactions with industrial chemicals. These chemicals are restricted by the UN’s Montreal Protocol, but they last so long in the atmosphere that damage is expected to continue for decades.
