We probably aren't headed for 8 degrees of heating, based on what we know today. There are a lot of "out there" scenarios that don't make it into sober, conservative scientific reports from the IPCC, because they recognize how important it is that people take their warnings seriously, and they don't want to mention anything they don't have very clear evidence for already. One of my "favorites" is the "world without clouds" scenario, which for the record, I consider unlikely, but is horrifying to imagine: https://www.quantamagazine.org/cloud-loss-could-add-8-degrees-to-global-warming-20190225/ https://www.quantamagazine.org/cloud-loss-could-add-8-degree... What we're dealing with are "unknown unknowns": what tipping points might exist that we don't know about, that might result in more warming faster than expected based on today's science? We shouldn't take those kind of existential risks.
