Watts Up With That shows that another “scare” that cause massive monetary change in business practices and personal inconvenience was in fact, a fraud, not linked to the ozone hole!
NASA Reveals New Results From Inside the Ozone Hole – Dec. 11, 2013
The area of the ozone hole, such as in October 2013 (above), is one way to view the ozone hole from year to year. However, the classic metrics have limitations.
NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and found that declining chlorine in the stratosphere has not yet caused a recovery of the ozone hole.
More than 20 years after the Montreal Protocol agreement limited human emissions of ozone-depleting substances, satellites have monitored the area of the annual ozone hole and watched it essentially stabilize, ceasing to grow substantially larger. However, two new studies show that signs of recovery are not yet present, and that temperature and winds are still driving any annual changes in ozone hole size.
“Ozone holes with smaller areas and a larger total amount of ozone are not necessarily evidence of recovery attributable to the expected chlorine decline,” said Susan Strahan of NASA’s Goddard Space Flight Center in Greenbelt, Md. “That assumption is like trying to understand what’s wrong with your car’s engine without lifting the hood.”
To find out what’s been happening under the ozone hole’s hood, Strahan and Natalya Kramarova, also of NASA Goddard, used satellite data to peer inside the hole. The research was presented Wednesday at the annual meeting of the American Geophysical Union in San Francisco.
