TBF there are far, far too many technological solutions that are “science will save us” but haven’t been fully fleshed out, studied, or require some modest form of unobtainium to work in mass deployment. Also, a huge chunk of those solutions would have to have been implemented 20 years ago, yet haven’t even made it off the proverbial drawing board yet.
IMO solutions need to be implemented now, like wind, solar, especially nuclear power, EV, etc. Yeah, nuclear is temporary, and yes, nothing stays in place longer than a temporary solution, but it’s a known and can be built now rather than yet another 5-15 years of waiting for untried tech solutions. Unfortunately the comic isn’t entirely wrong, we are going to need to lose some things if we want to save ourselves.
