The Antarctica ozone hole is the smallest it has been in five years, according to research from Niwa, the National Institute of Water and Atmospheric Research.

Satellite data combined with ground-base measurements show the hole reached a maximum area of about 22 million square kilometres this year, compared with 24 million sq km last year.
