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.

The Great Global Warming Swindle "the film poked some very big holes in the global warming consensus", and argued "we could do with more anti-conformist films from 'mavericks' like Durkin". "The Times"'s science editor Mark Henderson listed a number of points where, in his opinion, "Channel 4 got it wrong over climate change". He highlighted the feedback argument for the ice core data, the measurement error explanation for temperatures in the troposphere, and the sulphate cooling argument for mid-20th century cooling. Janet Daley, writing in "The Daily Telegraph" in a column headlined "The Green Lobby Must Not Stifle The Debate", noted that "Among those who
