Those peaks only go back half a million years. They don't even go back as far as the dinosaur mass extinction 65 million years ago. From that little graph, we can't even tell what the mean atmospheric concentration of CO2 has been over the past half billion years, let alone the lifetime of the planet. 65ppm increase in CO2 isn't very significant, overall.

It's common sense Win. All the carbon we're putting into the atmosphere, was already there at least once in Earth's history. The doomsayers act as if we're introducing carbon into the system ex nihilo and the world is going to end a muggy death. That just belies all sense.
