Scientists have discovered that the Ozone layer above the Arctic has developed a "rare and very large hole". Experts have attributed this to "low temperatures in the atmosphere above the north pole".

While there are concerns among a section of the scientific fraternity, others say that the hole will disappear in the coming weeks. As quoted by some media reports, the experts are of the view that the gigantic hole will probably not pose any environmental problems.

New York Post quotes Paul Newman, NASA's Chief Scientist for Earth Sciences, as saying this: “It’s the unusual temperatures this year that led to unusual levels of polar stratospheric clouds, which led to unusual ozone depletion."

He and others believe that the lower temperatures have nothing to do with the ongoing lockdown in large parts of the world.
