FWIW, it actually looks like we're on a path to 2.5-2.9 °C of warming with current policies, and nearly another 1°C reduction with current pledges which are indeed much less likely to fully materialise. Via https://en.wikipedia.org/wiki/Climate_change#/media/File:Gre... which appears to use 2021 data. The "no climate policies" scenario is shown as having the lower error margin actually above +4°C
This is true, I actually used 2° C as a shorthand for 2° C - 3° C. I shouldn’t have done that. I actually believe we are more likely to be closer to 3° C at the end of this century than 2° C.
