USA, Russia and others point missiles at plenty of places too - that is not a reason or even valid excuse.

I do think it was absurd China (and to a lesser extent India) came out of Paris with an almost limitless potential to increase emissions until 2030. Neither are undeveloped and remotely like the world's poorest.

A more sensible approach would have been to tie subsidy to each, and every trade deal. An EU or USA that truly cared about emissions would impose a carbon or renewables levy on products coming in from China and others. The US would push their pet the WTO to bake in emissions into global trade rules.

Had any of that been done round about Rio, or even as late as Paris, we might have a far more optimistic outlook.
