I'm honestly confused as to whether or not you are willfully trolling, tricking yourself, or just very scared. You're playing the exact tricks here that I just pointed out in the previous comment but I'm genuinely unsure of your motives. (btw, I don't think you're an idiot, I don't think most climate skeptics are idiots, I think they're terrified beyond what they themselves even realize)
The page you linked to says that RCP 8.5 is very unlikely, but none of the "code red" reports claim otherwise.
All of the "code red" reports claim that we are virtually certain to be unable to stay below 1.5 preindustrial. This is RCP 4.5 and above. Something that if we had this conversation 20 years ago was also viewed as very unlikely.
I think either you don't know or are wildly underestimating the severe impact that these alternative pathways will have on human populations. RCP 8.5 is as horrific as it is unlikely, but all the other pathways we are rushing towards are still absolutely "code red".
In the early 2000s most people earnestly thought we wouldn't get past 1C, now that is impossible.
It's not even worth getting into all the ways that many people agree the IPCC reports tend to be a bit conservative. I'm fine throwing out all of these concerns, and sticking with just the report, but even with just the report, even on RCP 4.5, we're in very real trouble. It is absolutely a 'code red'.
