Ozone hole grows

April 1992
New Scientist;4/4/92, Vol. 134 Issue 1815, p11
Reports that Japan's Meteorological Agency announced that the ozone hole over Antarctica has increased 13-fold in the past ten years. Now covers 17 million square kilometers; Based on data from American NASA satellites and Antarctic research stations; In Japan greatest loss of ozone (4.5 percent over past ten years) occurred over city of Sapporo.
