You are quoting "The majority of studies..." but I am not sure where you are pulling that from.
I have an issue with that quote since it is absolutely wrong about shipping and air trasport.
Edit:
And furthermore, you can't just abandon a significant sector and expect to pick it up later on.
There is tremendous momentum in each sector and to just focus on one, at the behest of others, is a TERRIBLE idea. Each sector does not exist in a vacuum. They all have supporting industries that also need to be developed and planned out. To put everything into renewables, is irresponsible at best. If we don't subsidize it all all. Then it will be a stillborn process that will never see anything outside an office.
Great, we now have 100% renewables, but we've had elevated CO2 for decades and now we have to spin up carbon capture from scratch because someone had the great idea to drop everything else. So add another 20 years for that to work up. We don't have that luxury.
Yeah, I got pinged twice, in one visit because I moved shit around, trying to organize.
Way more false positives, in my opinions.
