This seems to be a weird misconception about climate change, that the earth getting hotter will somehow end all life. That’s very doubtful. All the plants will love the new greenhouse, lots of energy in the atmosphere, rain every day, the whole planet a tropical paradise. It’s the humans and some other species who’ll be heavily inconvenienced. Solving climate change is mostly so we can stay comfortable and not have to deal with more ecological crises and refugees.

If it gets much warmer than that, and a run-away greenhouse effect would ensure that, only algae and some bacteria survive a while longer. Once the oceans are boiling, it's hard to imagine any life surviving though. There doesn't seem consensus on whether Earth could truly reach a runaway greenhouse state or would rather just settle at a higher temperature. In any case, only the ecological (and consequently economic) crises and refugees problem are the ones currently living people will be affected by, but that ought to be enough to take action.
