Wow this is the first time I've seen this argument used for the USA. "Only" 15% of global emissions - out of 195 countries. It's still the world's second biggest emitter - I think it would slow down global warming a lot if the US cut emissions. Usually this argument is trotted out in Australia, which is responsible for 1% of global emissions.
