Has the hole in the ozone closed
Answers
Answer:
The largest-ever tear in the ozone layer over the Arctic has finally closed, scientists have confirmed.
The hole formed earlier this year and was being tracked by experts at Copernicus' Atmospheric Monitoring Service (CAMS).
The ozone typically sits between nine and 22 miles above the Earth's surface and is a protective shield that is responsible for absorbing the sun's UV rays, which are harmful to humans and the planet.
According to scientists, a rupture this big had not been seen for almost a decade.
However, while some had assumed the 'unusual' tear was man-made, researchers at CAMS claimed that this was probably not the case, instead it was caused by a particularly strong and 'long-lived' polar vortex.
Therefore, the reduction in pollution created during lockdown has likely made no impact. But it's still great news, nonetheless.
