My comment was tongue in cheek. Solar and AC are a good combo.
I'd argue there's still a energy+climate reckoning coming where energy won't be as abundant as it has been and high energy use activities (like AC) will be more challenging. the EROEI (Energy Return on Energy Invested) of renewables/low-carbon are much lower than peak fossil fuels.
Incidentally I'm the same as you I'm so socialised on sleeping under something I do it regardless of temperature
It will keep happening until we recognise that public transport is public good that pays for itself by existing and not something that should self fund.
London is incredibly unusual in international cities where central funding is not the dominant source of funds.
