We have warmed the earth because we love comfort and money. We will never stop loving those things. So instead let's use the same systems to fix this (or at least slow things down).
As an individual my largest carbon impact is air travel. I like to go places, it's one of the main things I work to afford. Every single plane ticket I take should have a tax which is used to offset or capture the carbon emissions of my flight. I will pay it. Anyone not willing to pay it will have to fly less. Any airlines that can't operate under the tax will not operate.
Now do the same thing for corporate polluters, packaging waste, etc. If a country won't do this for domestic goods we can at least impose climate tariffs at borders.
The only other thing that could work is some fantastic new technological solution, but let's not wait for that.
