But no one knows what "fairly slow" is. Also the climate collapse theories predict that once a certain tipping point is reached, its game over. If that is true then slow and stable increase still gets us to that point just a bit later.

In other words to make climate change stable do we need to reduce CO2 emissions, completely stop CO2 emission or remove CO2 and reduce the CO2 in the atmosphere?

We don't even know which of these 3 options would lead to the "fairly slow/stable" we want. It seems like we just do all 3 with no evidence of any real world effect whatsoever.
