This is an excellent and rigorous study, that supplements previous work and is in line with the best current research. 

The study could have a big impact to [help] design our adaptation plans -both at a national and local level- with ethics and environmental justice in mind. But it is uncertain in how society might respond in terms of consumption (especially energy consumption), and that also has be taken into account.  

The authors of this paper clearly show that the transition to sustainable energy sources is significantly less costly than the cost we are already ‘committed’ to bearing by our past greenhouse emissions, so we would have been much better off had we not delayed climate action for so long. 

Overall, however, this kind of modelling approach is not suitable to conclude much about the costs of climate change at the local level [...]. This approach does not account for the local peculiarities of our economic activities [...]. 

But, the fact we cannot conclude much from this work about the local impact does not detract from the main message, that we should rapidly converge to a net-zero world. Afterall, the argument for us, and for everyone else around the world, to work toward net zero is not that our actions matter locally, but that it is their global impact that is the reason for the urgency we need to adopt.
