I have a Fujitsu mini split that has been awesome in terms of bringing my electric bill down versus window units (we live in Maine, central A/C is less common here, and few homes were built with it until the 2000's). It does, like most splits, use R-410A, but I'd be happy to use something else if it didn't kill the efficiency. In parallel with refrigerants and efficiency, though, I wonder if the article misses on men…
Thanks to that effort made by many, "A 2005 IPCC review of ozone observations and model calculations concluded that the global amount of ozone has now approximately stabilized. Although considerable variability is expected from year to year, including in polar regions where depletion is largest, the ozone layer is expected to begin to recover in coming decades due to declining ozone-depleting substance concentrations, assuming full compliance with the Montreal Protocol."
