There's also the risk, according to some scientists, that if we cut our emissions overnight (I don't know how, like we all got together collectively and did at once or something), the climate could be significantly adversely affected by the shock drop. Cutting emissions entirely is also a no-win. So where's the balance?

There's also the issue that some countries (the US) are a lot more concerned about it than other countries (not naming names). Those other countries have every incentive to watch us flail around making the lives of our citizens harder (through taxation, meat reduction, other proposals) trying to cut emissions while they sit back and egg us on, and maybe pay lip service once in a while with the occasional inconsequential project.
