Chemicals That Eased One Woe Worsen Another

Hydroflurocarbons (HFC) have been widely used as substitute for chlorofluorocarbons, CFCs, (chemicals used in air conditioners, refrigerators, etc.) and other chemicals that have been targeted as depleting the ozone layer (the layer that protects the earth from UV radiation - cancer causing sun rays). HFCs are a much more powerful greenhouse gas contributor than CO2 and are now potentially creating a problem.
According to the recent paper, there will soon be many more of HFCs used, as developing countries become more prosperous and their people buy vehicles and air conditioners.
