FRISCO — The ozone hole over Antarctica didn’t change much from last year, scientists said this week, pointing to weather and climate variability as key factors in year-to-year variability.

The single-day maximum area was similar to that in 2013, which reached 9.3 million square miles. The largest single-day ozone hole ever recorded by satellite was 11.5 million square miles) on Sept. 9, 2000. Overall, the 2014 ozone hole is smaller than the large holes of the 1998–2006 period, and is comparable to 2010, 2012, and 2013.
