Earth will survive regardless of the CO2 levels. In past periods, the CO2 levels have been higher than those of today, but it was a different climate that humans evolved in. I think the question would be better if you asked how long humans could survive with the current CO2 levels. The answer I do not know and could only speculate. I will say though if we do not change our lifestyle to lower CO2 emissions, we will create a climate that is unfavorable to that of what humans evolved in.
