Nice chart: seems to clearly show CO2 as a lagging indicator of climate wramth-- the wramer it is, the moister it is, and the more stuff rots.
I found this chart on a website, but if you go to N.O.A.A you can actually find the raw data which is useful for evaluating later trends.
Yes, there has been an increase in C02 since humanity arrived on the scene, but there is nothing to say that increasing C02 at the current global temperature, will cause an increase in temperature.
If anything, one might think it would cause temperature to drop since every time the temperature reached this level, and the CO2 reached this level or higher, the global temperature started to drop.
