I really like the spirit of this post and I agree to pretty much everything you stated. I am however worried, that adoption of decarbonisation is not progressing close to fast enough. I am also worried that the 2°C goal is not ambitious enough. Changes in the planets albedo, defrosting the permafrost may bring up irreversible change before the 2° carbon budget is exhausted.
To remain inside the 1.5°C limit we only have like 8 years left at current exhaust. While I believe that a future decarbonised society will be a happier place, I also believe that climate catastrophe is inevitable. The 140*10^6 expected refugees will happen and we will loose coastal lines around the planet. I am not sure what's left of the eco system will be able to sustain our species.
I nevertheless think that this next big thing is the next big thing, and we must proceed at highest speed regardless.
