Largest-ever hole in the ozone layer above Arctic finally closes | Euronews


The largest hole ever observed in the ozone layer over the Arctic has closed, says Copernicus' Atmospheric Monitoring Service.

Scientists spotted signs in late March of a rare hole forming and it was thought to be the result of low temperatures at the north pole.

The ozone layer shields the Earth from most of the Sun's ultraviolet radiation, which is a major cause of skin cancer.

The record-breaking hole would only have posed a direct threat to humans if it had of moved further south to populated areas.

But on Thursday (April 23), Copernicus - the EU's earth monitoring programme - announced the hole had now closed.
