Brian Smith makes a simple (and IMO) valid point: given that temperatures will continue to increase and that even poor people in the developed world can afford AC, we should do more to ensure everyone in the world has reliable access to AC.
The responses are comical. Jed asks "Do you get paid by the oil companies for this erming?" and Dennis confidently asserts that Brian's approach will lead to 5-6C of warming and 60-meter sea level rise.
My plea to advocates of quick decarbonization: please answer Brian and others with proper arguments and references. Otherwise you're only preaching to the choir and you won't convince many more people. If you want to make substantial changes to the way we get energy and live more generally, you need broad public support. Thank you!
