@mjp2 These models have been repeatedly revised over the last so many years. I've seen this sort of thing so many times, it is constantly revised and conveniently used by politicians. Listen, I know CO2 is a greenhouse gas, I get it, do you understand that it is at lower atmospheric concentration now than it was when the temperature of the earth was much higher in the past? It is only 1 variable amongst many.
It is at lower levels now than that at which plant life optimally thrives. If it had gone down from 280ppm by 120ppm plants would have started to struggle. This is the truth, you can look at ever changing models and fret whilst the politicians walk it all to the bank.
