Earth heals itself in several ways from any changes that may aim to harm her. Recently, the largest ozone layer hole above the arctic has healed totally and it has not much to do with the lockdown which was imposed in various regions of the world due to the COVID-19 pandemic. UN World Meteorological Organization (WMO) on May 1st, has announced it as, “A ‘record-level’ ozone hole over the Arctic, the biggest since 2011, has now closed”.
Speaking to reporters as part of UN briefing in Geneva, WMO spokesperson Clare Nullis, said that the combined factors of ozone depleting substances and cold winter in stratosphere, has depleted the layer that lies between 12 to 50 kms in the atmosphere. "These two factors combined to give a very high level of depletion which was worse than the one we saw in 2011. It's now back to normal again. the ozone hole has closed," Nullis said.
Earlier this month, a large hole in the ozone layer which was more than 1 million square kilometers, was found out by scientists. The low temperature of the North Pole was thought to be the cause behind the hole. Had the hole moved towards south due to air currents, then it must have posed a major threat to the human population. Two services which were intervening on behalf of European commission, namely Copernicus Atmosphere Monitoring Service (CAMS) and Copernicus Climate Change Service (CCCS), gave a confirmation message to the world that the hole is completely closed now. They also mentioned that the decrease in pollution due to lockdown is not the major reason for the successful healing of the large ozone hole.
The unprecedented 2020 northern hemisphere #OzoneHole has come to an end. The #PolarVortex split, allowing #ozone-rich air into the Arctic, closely matching last week's forecast from the #CopernicusAtmosphere Monitoring Service.
