(Worthy News) – The ozone hole Antarctica is the smallest this year since scientists started tracking its thinning in 1982, federal researchers announced on Monday.
According to satellite measurements, the hole reached its annual peak at 6.3 million square miles and then shrank to less than 3.9 million square miles in September and October. Typically the hole reaches a maximum size of about 8 million square miles, but at its largest in 2006, the ozone hole measured 10.6 million square miles.
Researchers attribute this year’s small size to a sudden warming event in the stratosphere, which disturbed the thinning process. [ Source: US News and World Report (Read More…) ]
