My understanding is that there was even more CO2 in the atmosphere than all the carbon stored in fossil fuels. Every carbon based life form was probably at one time free CO2 and a whole lot of rock.

As I said, even if by some insight scientists were able to show today that indeed all that CO2 was in the atmosphere at once, that would still not make the earth safe from greenhouse effects.

To give you a simple example, scientists know that the Earth at some point was all molten lava and volcanic activity. Does that make it ok for humans if the earth was to become one huge volcano today?
