Someone who didn't suck hard at both logic and science would understand the craziness of claiming we have to heat the earth now to avert an ice age in 20,000 years. It's like claiming you have to start running the furnace full blast in July so that the house will be warm in winter. It's so dang stupid, you have to wonder if the person saying it is capable of feeding themselves.
However, that's still not as stupid as you claiming CO2 "displaced" other gases from the atmosphere. That's in the running for the single dumbest thing I've ever read here.
And, for the third time (you seem to have a habit of evading simple questions), explain to everyone how the observed increase in CO2 levels squares with your whackaloon claim that the the CO2 cycle can't be "overwhelmed." I mean, we know it was "overwhelmed", because we directly measure it being "overwhelmed".
