It's been billions of years before I existed, and potentially trillions of years afterwards. I'm incredibly lucky to be aware and thinking, so why should I complain about stuff happening after my spark of awareness has faded?

This is exactly how I do it. In the long run, none of this shit matters, and nothing will be remembered. The planet has rebooted several times in its history, what are the odds that this particular sentient being would be here to witness it? Enjoy the ride while it lasts, make sure any survivors of the collapse remember who the guilty parties are.

Satisfaction that the rich are going to get fucked by climate catastrophe and ecosystem collapse just as much as everyone else. The climate change deniers will starve just like the rest of us.

They will eventually... but in the mean time it definitely doesn't affect them the same as the rest of us. When some places start becoming unlivable, they can just move to the ones that will last longer. When food and water becomes scarce they'll hoard what's left. When the air becomes unhealthy to breathe they'll have filters. It's gonna be a long time before they see any actual consequences they can't buy their way out of.

Nothing humanity has done will survive.

I wouldn't say nothing, after all we've sent a bunch of stuff speeding out of the Solar System and will probably send more in the future.

The last time the climate changed this much it destroyed hereditary monarchies.

Maybe this time it will take out capitalism.
