As for a billion years, no one is expecting to live that long but we have every expectations of living for a couple more thousand years until we gain the capability of traveling between stars and planting seeds of human civilization. Now we may not have that chance.
If I were you, I wouldn't be worry about too much CO2. I worry that there won't be enough of it. The planet is dying. CO2 levels have dropped. Grasslands now dominate where once jungles lived because there isn't that much CO2 anymore. Not in our lifetime but in a billion years or so, there would not be enough CO2 to support more than bacteria.[/QUOTE]
