Newly developed ozone hold over Arctic closes itself up

  • European Commission’s Copernicus satellite discovered the unusual hole in the ozone over the Arctic.
  • Holes over Antarctic are common but not over the Arctic.
  • The same satellite now has evidence that the hole has closed.
  • The Arctic hole isn’t traced to human activity, but to what the European Space Agency called “unusual atmospheric conditions,” including a powerful polar vortex of swirling cold air.
