The solution to climate change requires indeed keeping large numbers of people poor and making existing people poorer. And it will fail indeed because of populist backlash. We should plan indeed for climate change, though not sure what to personally do beyond buying a praying book (100% dead serious).

Sobering: As of 2021, there is no 'western lifestyle' country on the face of the Earth that has emissions in line with the requirements of the Paris accord emissions, which is about 2.5 CO2 t/year/capita for a global population of 10 billion (2050 estimate). Even countries like Sweden, Switzerland of France, which are >90% nuclear & renewable in their electricity production, still have 4.5, 4.7 and 5.1 t CO2 t/year/capita. I have yet to hear concrete proposals of where the 50% cuts should come from, other than large scale technologies that have not been developed yet.
