The Ozone Fiction

Timothy Birdnow

Dr. Tim Ball gives us the story of ozone depletion, or rather the fiction of ozone depletion that became all the rage.

From the article:

"The angle at which solar rays strike the atmosphere decreases from 90° at the equator to 0° at the poles, so the amount of ultraviolet radiation striking the surface decreases dramatically. As Professor Fred Singer explained in his Congressional testimony (September 20, 1995),

A projected 10 percent UV increase from a worst-case global ozone depletion is the equivalent of moving just 60 miles closer to the equator… New Yorkers moving to Florida experience a more than 200 percent increase in UV because of the change of latitude.

Increased lifespan explains the increase in skin cancer, not ozone thinning.

The problem began with a hypothesis. Molina and Rowland theorized CFCs went to the stratosphere and destroyed ozone. Their laboratory studies showed CFCs destroyed ozone in the presence of high frequency UV. They didn’t, and couldn’t, simulate atmospheric conditions in the Ozone Layer. Now ideology took over; determined to prove, rather than disprove as proper science requires. The imperative was to ban CFCs, not to test the theory. Like the Anthropogenic Global Warming (AGW) hypothesis, the consensus was determined and contradictory or conflicting research ignored.

Central to the CFC hypothesis is the assumption that UV levels are constant. This meant measured variations in ozone were caused by something else. Environmentalism demanded a human cause and Molina and Rowland provided the answer. We now know UV varies considerably, more than enough to explain the variations.

CFCs are four times denser than air, so there was a transport question – how did they get to 15 km above the surface? The answer is they didn’t. The active portion, that is the part that destroys ozone, is the first ‘C’ – or chlorine. It is part of a growing family of Ozone Depleting Substances (ODS). In a laboratory, a chemical is placed in a chamber with ozone. If the ozone is destroyed, then the chemical is designated an ODS and banned."

If ozone turned out to be a nonstory, how much more will be global warming?
