To compound the problem, the liquids used for all this comfort — first chlorofluorocarbons and now hydrofluorocarbons — are super-strength greenhouse gases.

人们为了这份舒适而使用的液体冷却剂——先是氯氟化碳现在是氢氟化碳——都是超强度的温室气体，而这让问题变得更糟。

By the mid-1930s, most refrigerators and air conditioners used chlorofluorocarbons – sometimes known under the trademark Freon – which were non-flammable, and safer to use.

到了20世纪30年代中期，大多数冰箱和空调都使用了氟氯化碳，有时以氟利昂的商标命名，它们不易燃，使用起来更安全。

About 80% of the chlorine in the atmosphere is a legacy of chlorofluorocarbons, chemicals used in aerosol sprays and as refrigerants starting in the 1930s.
