The Earth atmosphere contained about 8000 PPM CO2 and temperature about 85F back in the Mesozoic/Jurassic Era because dinosaurs were driving SUVs and gas golf carts. If the Earth ever returns to it's optimal temperature of 69F (We are at about 60F now...Still coming out of a long Ice Age), we will see some pretty nasty and large plants evolve and perhaps return of dinosaurs over time (They taste like chicken I hear). Atmospheric CO2 will be about 1500 PPM at 69F.

And yet another poster wants to confuse the gullible, the true believers and the fully indoctrinated with the facts. Now cut it out---just like Greek Mythology, the cult of global warming will fade away if too many of them get educated.
