This is an excellent review of what needs to be done immediately by all countries. China has simply and easily replaced the failing US as the lead technology and the planetary lead in climate correction. The tremendous power that this will deliver to China as climate disasters destroy regions of the globe where action has been stalled by incompetent governments is difficult to visualize.
By doing what must be done and choosing to act at the planetary level China is setting the model for the next decades. While it is what is required to save human civilization from the largest threat in our history it also works as realpolitik for influence everywhere right now. Africa, Central Asia, and southern Europe now look to China for growth.
