> the latter will command both extreme heating and possibly also cooling

I fully disagree with your use of "extreme" here, you have no evidence for that. Homes naturally have insulation which would mean the +22 temperatures would heat them, and some of that leftover heat would therefore reduce the need for heating. Indeed, it seems likely to me that the rate of heat leach would keep both these situations identical except for the fact you managed to inject "also using AC" in here like anyone ever does that.

Quite a weak argument.

The overall climate of our planet has nothing to do with the energy cost to heat a home.
