One not very well known fact is that even if we stop emissions today, the elevated CO₂ levels will remain for many centuries.
They way I think/hope we can fix this is two parts:
1. The only way I think you can get rid of the excess CO₂ at scale is to permanently sequester it underground. The oil/gas industry can cheaply deposit huge amounts of gas there. The unsolved problem is extracting enough CO₂ from the atmosphere at reasonable cost. People are working on that, but it will probably be decades before it's is approaching practicality.
Which is why we need to do this in the meantime:
2. Spray the stratosphere with SO₂. This reflects some some sunlight and cools the planet. It sounds scary, but is actually safe: https://makesunsets.com/pages/new-faq
