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.

Public opinion on global warming drop in concern in 2008 is unique compared to other environmental issues. Considered in the context of environmental issues, Americans consider global warming as a less critical concern than the pollution of rivers, lakes, and drinking water; toxic waste; fresh water needs; air pollution; damage to the ozone layer; and the loss of tropical rain forests. However, Americans prioritize global warming over species extinction and acid rain issues. Since 2000 the partisan gap has grown as Republican and Democratic views diverge.
