Global yearly average temperature keeps increasing because not directly by our emissions, but the excess of CO2 and other GHG (that yes, that was mostly our emissions, mostly adding fossil carbon to the cycle). This way we are going head-first towards dangerous levels of it (that cause extreme weather, trigger positive feedback loops and other not so nice things that you won't want to live through)
Keeping our current emissions will keep increasing that excess of CO2 and GHG, getting to some sort of net-zero (not the proposed one in COP26, but one counting with all kind of mankind carbon emissions AND the one emitted by the current already triggered feedback loops) will keep more or less the same amount of GHG in the atmosphere as CO2 lasts there for centuries.
The only way to have some hope that things don't keep getting worse is to manage to do negative emissions, and bring GHG down to pre-industrial levels, or even lower, if we want to drop in some way the global temperature average that had been steady rising for many decades, as that extra temperature is fueling positive feedback loops.
If there is a shortcut for making that temperature drop, because natural processes like the AMOC or whatever, the better, because we are not fighting for how livable will be a particular region of the world, but the entire world.
