Seems to me that we should be trying to make people's lives easier in the meantime, rather than making them miserable and poor with bonkers legislation, regulation and taxes.
Fanatics still seem to be stuck in the "bargaining" phase, I feel ahead of the curve to be honest.
1. It's not happening
2. It's not our fault
3. It's not that bad
4. We can't solve it
5. It's too late
So in that framing we're on step 4 or 5 I think.6. Let's (try to) do something about it.
I think solar radiation management is the only last-ditch idea that might pull things out.
In terms of outcomes, "climate change is real but nothing we could do would have any effect" is identical to "climate change is fake", which is why you're getting lumped in with the deniers.
Canada implemented carbon taxes to reduce emissions. Emissions still rose and everything just became more expensive.
Even if it's a net cost though... it's not like there isn't enough money to go around. If only there was a way to redistribute that wealth so that poor people didn't get even poorer.
I really truly don't think the only two options are "do nothing" or "do something but at such a great cost to people's quality of life that the cost outweighs the many millions or billions of lives saved".
Any so-called attempt to "redistribute wealth" has led to massive inflation and a borderline humanitarian crisis in our cities with people losing their homes and becoming addicted to deadly drugs on the streets.
