Read also the excellent paper of Bjorn Lomborg, seriously argued in favour of a climate policy based on adaptation rather than on a horribly costly and ineffective CO2 mitigation. His best scenario is “Fossil fuelled development”, using resources actually available “to produce rapid technological progress and development of human capital as the path to sustainable development”. The benefit (avoidance of damages)-to-cost ratio is at least an order of magnitude better than the path to 2 ℃ or 1.5 ℃ than is enshrined in the Paris accord. See https://blog.mr-int.ch/?p=6392 Reply
