> Deep underground sequestration is the only viable strategy if your goal is total CO2 reduction in the atmosphere.

That is untrue. So untrue it seems like a deliberate lie.

The only solution is to stop pumping CO2 in into the atmosphere.

There are mitigations. Building huge machines to sequester relatively small amounts of carbon in underground chambers is probably a mitigation. It seems to me that there are better ways and these sorts of ideas are not worth the opportunity cost.

Even if we stopped burning fossil fuels 100%, we still have too much carbon in the atmosphere no?

Yes but not too much that we can't just wait it out. It's not like the planet is a hot fireball right now. If you wanted to make the planet more hospitable to humans, you would most likely attempt to stop desertification and deforestation rather than attempt CO2 capture. Increased water retention will help with droughts more than a 1°C reduction in global temperatures.

Of course, we are going to see far more than a 1°C increase which is why it is worth doing.
