I wonder. At some point, deliberately raising your emissions will be regarded as a crime on a par with genocide. Because it is genocide, it's just slow and the responsibility is shared. I wonder at what point we will see the first threats to declare war if a country wilfully refuses to cut its GHG emissions.
Note that I do not doubt this will happen. Just when and who.
