The planet will do fine, but even stating such a thing is still commit anthropomorphism. The planet will continue to exist for a long time, no matter what the fate of mankind will be.
Even life is most likely to continue prospering in a way or in an other.
We, the human species, are not the planet. Let’s stop to use formulation like "the planet is in danger". No it’s not. The biosphere already went through five major extinction, and life is still there.
Humans aren't the only species evolved to live in this particular climate, and we won't be the only species impacted by an extreme outcome of climate change. Long term, of course, the planet will survive, and hopefully many species will thrive in our absence. But many will go extinct, and it will have been our fault. On a long enough time scale, sure, nothing matters really, the sun will explode and all our flyer campagins will have been for nothing. But we experience a much smaller timescale, and it'd be great if we gave some thought to not boiling the reefs and setting fire to the koalas while we're here.
The top level post is correct. It is a matter of minimizing suffering.
It will only be once the next generation of leaders comes into power, maybe even the generation after that, as they will be living the climate reality enough to want to fix it (whichever level of severity it ends up being). At which point we'll be needing to focus on remediation still, before finally, hopefully, creating some kind of sustainable version of our current societies.
