I think that the banng of HFCs is a pretty good example of collective action. Also, it's important to realize that climate change, as we best understand it right now, is not a "or perish" type of situation. RCP8.5 has now been soundly eliminated from the set of potential climate trajectories, so what we're left with is a question of 1) how much mass migration will be forced upon the world, with concomitant wars and social strife, and 2) how much economic loss results from that, as well as from lost opportunity by not adopting cheaper renewable energy routes. Technological innovation has done something absolutely remarkable: the future with the cheapest and most abundant energy is the one that switches to renewable energy and storage the fastest. Every day we delay, not only do we end up with a worse climate outcome, but we also just light money on fire, with worse economic efficiency. And in economies built on the continual compounding interest of technological advancement, we subject humanity to far greater poverty for every day we delay the transition. Most of the world will benefit from this technological change happening quickly. There will be some outliers, like the US, that choose to be poorer and less influential by actively subverting renewable energy in the marketplace (the Trump administration has done a huge amount of economic damage in only a small amount of time), but the US will come around. Texas is leading the way, because they are actually market driven more than they are politically driven, but the rest of the US is kind of screwed on that front for a while. |
