The point of no return is classified as 4C warming by the International Paris Climate Accord (IPCC).

To give you some indication we're currently between 0.8 and 1.2C warming and we're projected to reach 1.5C by 2030 and 2.0C by 2050. If we keep polluting at 2022's rate permanently then we'll reach 4C warming between 2250-2300.

So while climate change is a really bad proposition we're most likely not going to reach a society ending treshold unless humanity is so stupid it never curbed emmissions before 2250.
