Only link I saw was the Drudge one and no video loaded... might be my setup though.

As far as CO2 goes it's more than just a global warming concern. CO2 is also absorbed by the ocean. I'll not practice similar sophism by pretending that's the end of the story but I hope you can agree a more acidic ocean is not a good thing.

I think the next page in that story is oceanic microcritters (freshwater ones too -- you can tell freshwater limestone from marine limestone) using that dissolved CO2 to make calcium carbonate for their shells. This CaCO3 drifts down to the seafloor to make deposits of limestone.

One reason (besides the Moon's tidal effects helping in primitive eons to strip some atmosphere away) Earth's atmosphere doesn't much resemble Venus's is because because the plankton and radiolarians sequestered so much of the CO2 to make the limestone.
