If hydrofluorocarbons (HFCs) are to have long-term viability, the low-global warming potential (GWP) versions will have to separate themselves from high-GWP types. And the survivors will have to play their part in energy efficiencies, especially in commercial buildings.
As this is being written temperatures are near 100°F here on the Illinois/Wisconsin border and a drought is in full force. The hue and cry is, “See, see, global warming! Told you it was real!” But folks from Europe were telling me that the Old World was experiencing one the coolest and wettest summers on record.
