Hole in ozone layer shrinks
A GAPING hole in the ozone layer over Antarctica appears to have shrunk by about 20 per cent from last year’s record-breaking size, scientists said today.
Experts in New Zealand said their measurements backed up satellite data showing the hole peaked at about nine million square miles compared with 11 million square miles in 2003.
Scientist Stephen Wood said: "We need to see smaller ozone holes over a number of years before we can say for certain that ozone is recovering."
