"Failure to cut carbon emissions means ‘rapid transformation of societies’ is only option to limit impacts"
The UN implies that the only way we'll be able to stop global warming, is if we implement socialism immediatly.
The 1.5°C degree limit is important because once we cross it, a domino-effect of self-reinforcing mechanisms is activated, see:

The IPCC reports since at least 2016 (when I started reading them) only had one "good path", and that always involved sudden and immediate decarbonization along with total international cooperation, neither of which were ever going to happen.
But yeah, it's grim.
