R-410A bromine or chlorine, R-410A (which contains only fluorine) does not contribute to ozone depletion, and is therefore becoming more widely used, as ozone-depleting refrigerants like R-22 are phased out. However, it has a high global warming potential (1700 times the effect of carbon dioxide), similar to that of R-22. Since R-410A allows for higher SEER ratings than an R-22 system, by reducing power consumption, the overall impact on global warming of R-410A systems will be substantially lower than that of R-22 systems due to reduced greenhouse gas emissions from power plants.

Media coverage of global warming a new ice age? An editorial in The Time magazine on June 24, 1974, quoted concerned scientists as voicing alarm over the atmosphere 'growing gradually cooler for the past three decades', 'the unexpected persistence and thickness of pack ice in the waters around Iceland,' and other harbingers of an ice age that could prove 'catastrophic.' Man was blamed for global cooling as he is blamed today for global warming"., and the "Irish Independent" published an article claiming that "The widespread alarm over global warming is only the latest scare about the environment to come our way since the 1960s. Let's
