Man has added CO2 to the atmosphere,

But let's not forget that Man only burned the results of previous plant life. So Nature stored the CO2 in fossil fuels, and Man just burned it again.

Man did not create the CO2.

[Pox]

That is accurate. Also consider that Earth accumulate more matter from space on a daily basis. I have no doubt that the CO2 that falls to Earth from space is negligible, but it is something that needs to be factored in.

As far as the rise in sea levels, is the amount of groundwater extracted by Mankind from the underground water table on land factored into these equations as well?

So many variables...
