Data from NASA shows that this year’s hole in the ozone layer above Antarctica remains largely unchanged. On September 9, 2014, it measured 24.1m square km, which is roughly the size of North America; only a little smaller than the largest hole ever observed, which occurred in the same spot in 2000, and much the same as it was at its peak in 2010, 2012 and 2013.
