A bunch of us in the rest of the world are making great strides in reducing our greenhouse gas emissions without it tanking our economies. Australia is, per-capita, one of the worst offenders and we're on track to reach net zero by 2050.

I think your position is based on very cynical premises. There is no reason to assume with high confidence that humans will obliterate each other in that next 50 years (especially if we do something about one of the major stressors causing conflict)

There is also no reason to believe that reducing greenhouse gas emissions over 15-20 years will cause "more" damage than the worst impacts of climate change? Can you cite sources on this claim?

It is still possible to mitigate the worst effects of anthropogenic climate change.
