But... we are having issues right now? People aren't acting because there's no economic incentive, it is only in part due to denial or ignorance. Many of the world's leaders who have to power to shift the narrative are not doing so because it would be a short term economic loss and businesses aren't happy about it.

I mean, many technologies like carbon scrubbers already exist. Why aren't businesses buying them?

This is something we need to decide as a society to act on out of pure good faith, there will not be any profit to be made from the sacrifices that need to take place. People need to come to terms with just... being kinder. It would help if world leaders created jobs for this industry on a budget deficit and helped people get into those jobs.
