Earth is perfectly habitable with 10 degrees warming. The problem is that the jump in temperatures is way to fast. So biomes can not shift quickly enough, which causes huge problems. So right now the most important thing to do is to limit that jump. If we do not go too much higher, then most areas humans currently live in will still be habitable.
That much warming will also significantly shrink the part of the planet within the human climate niche. Even if it happened a bit more slowly, we’d end up with a lot fewer people as a result
