Ozone-Friendly Chemicals Lead to Warming
http://www.lasvegassun.com/sunbin/stories/tech/2006/aug...

Cool your home, warm the planet. When more than two dozen countries undertook in 1989 to fix the ozone hole over Antarctica, they began replacing chloroflourocarbons in refrigerators, air conditioners and hair spray.

But they had little idea that using other gases that contain chlorine or fluorine instead also would contribute greatly to global warming.

CFCs destroy ozone, the atmospheric layer that helps protect against the sun's most harmful rays, and trap the earth's heat, contributing to a rise in average surface temperatures.

In theory, the ban should have helped both problems. But the countries that first signed the Montreal Protocol 17 years ago failed to recognize that CFC users would seek out the cheapest available alternative.

but I think chloroflourocarbons, are made of chlorine, and flourine, both halogens. Bromine, Chlorine, flourine,and iodine are all halons. Why wouldn't they think they would do the same thing?
