What we need to do is to ruthlessly tax externalities that haven’t effectively been considered before, and use the proceeds to transition to an economy with net zero climate gas emissions. Then repay the damage with large-scale CO2 sequestering, multi-gigaton scale.
If economic growth is considered everything we value getting cheaper and more abundant over time, anthropogenic climate gas emissions can be considered a horrendous debt that needs to be repaid. This is achievable! It’s expensive, but doesn’t require a 1950s lifestyle for everyone.
