The messaging on this topic is interesting — too doom and gloom and you can turn people off, since it seems hopeless. Too rosey, and you come across as a science-denying dolt.
The hedline+lede here seem to strike a nice balance.
They definitely tried to strike a balance but they didn’t account for climate science itself tending to be too optimistic because certain mechanism may still be unknown. They didn’t even mention the possibility of tipping points/runaway events. And they focused entirely on the electric grid (not on heating, transportation, agriculture, etc.).
I think they’re right about electric grids overall getting cleaner though. Basically, I guess, we just need China to stop building coal plants at this point. That point can’t be too far out, given the economies.
