Of Hairspray and Half-Truths

Prior to the 1980s, CFCs, or Chlorofluorocarbons, were everywhere. They kept you comfortable in the form of coolant in your air conditioner. They were used in fire extinguishers. And they propelled the hairspray from the cans that made many of your favorite hairbands possible. But long before Whitesnake tried destroying music, CFCs were destroying the ozone layer. 

Ozone depletion led to “the hole in the ozone layer” which became big news in the 80s. It just kept growing and, wouldn’t you know it, we were the cause of it. Our insatiable thirst for cool air and White Rain was killing the planet. Heeding the warnings of scientists, researchers and environmentalists, drastic action was taken to eliminate CFCs from wide use. Here in this country, the EPA fannagled Congress into passing the Clean Air Act in 1990 to effectively ban or quickly phase out CFCs. 

But in life, like fashion, what once was trendy is questionable in retrospect. Recently NOAA, the National Oceanic and Atmospheric Administration, contridicted her fashionable sister, the EPA, and said that aerosols might not be so bad and might actually be cool. Literally.

It seems aerosol particles in the atmosphere may be offsetting greenhouse gas emissions and keeping global warming down to slow boil
