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 Real Global Warming Disaster in energy policies, the scientific evidence for global warming is becoming increasingly challenged. He asserts that global warming is not supported by a significant number of climate scientists, and criticises how the UN's Intergovernmental Panel on Climate Change (IPCC) presents evidence and data, in particular citing its reliance on potentially inaccurate global climate models to make temperature projections. Booker concludes, "it begins to look very possible that the nightmare vision of our planet being doomed" may be imaginary, and that, if so, "it will turn out to be one of the most expensive, destructive, and foolish mistakes the human race
