NASA On Air: Big Ozone Holes Headed For Extinction By 2040 (5/8/2015)

  • Released Friday, May 8, 2015

LEAD: NASA scientists report that the ozone hole over Antarctica is slowly recovering.

1. The ozone hole is the result of man-made chlorine and bromine chemicals reacting with thin ice clouds at 60,000 feet where temperatures are bitterly cold, less than –110 Degrees Fahrenheit.

2. The ozone hole varies from twice to three times the size of the United States.

3. Since the Montreal Protocol agreement in 1987, emissions have been regulated and ozone-depleting chemical levels have been slowly declining.

4. With a new analysis, NASA scientists say that the ozone hole will be consistently smaller than less than twice the United States.

TAG: Scientists will continue to use satellites to monitor the recovery of the ozone hole and they hope to see its full recovery before the end of the century.
