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 remained about 35%. Between 2010 and 2013, the number of Americans who believe the media under-reports the seriousness of global warming has been increasing, and the number who think media over-states it has been falling. According to a 2013 Gallup US opinion poll, 57% believe global warming is at least as bad as portrayed in the media (with 33% thinking media has downplayed global warming and 24% saying coverage is accurate). Less than half of Americans (41%) think the problem is not as bad as media portrays it. September 2011 Angus Reid Public Opinion poll found that Britons (43%) are
