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 Public opinion on global warming Public opinion on global warming is the aggregate of attitudes or beliefs held by the adult population concerning the science, economics, and politics of global warming. It is affected by media coverage of climate change. A 2007–2008 Gallup Poll surveyed individuals in 128 countries. This poll queried whether the respondent knew of global warming. Those who had a basic concept of global warming didn’t necessarily connect it to human activities, revealing that a knowledge of global warming and the knowledge that it’s human-induced are two separate things. Over a third of the world's population were
