The ozone hole over the Arctic, which reached a “record size” in March, closed. This is reported by the World Meteorological Organization (WMO), which is a UN agency.

According to the organization, the destruction of the ozone layer in March was caused by both ozone-depleting substances in the atmosphere and very low temperatures in the stratosphere in winter. As a result, the level of ozone depletion became very high, breaking the 2011 record. Nevertheless, a month later the situation changed dramatically.

“The ozone hole closed in April with increasing temperature in the stratosphere, which led to the influx of ozone-rich air from the lower atmosphere,” the WMO explained.

According to Reuters, an official representative of the WMO office, Claire Nullis, at a briefing in Geneva, said that this phenomenon is in no way associated with a decrease in environmental pollution in the context of the COVID-19 pandemic.
