Re: Impartiality about what?
"Of course, all this assumes that we can influence the CO2 cycle."
That's not an assumption at all. There's overwhelming evidence that we are.
"The natural movements of CO2 are far greater than any human inputs or sinks, and there is really no indication that human activity can alter the concentrations - it is just treated as a matter of faith that stopping human output will leave all other processes working in exactly the same way at a lesser concentration."
The natural movements of CO2 are currently a net sink. Overwhelming evidence that this is because of the amount of CO2 in the atmosphere being so high. Which means if we stop emitting nature isn't going to suddenly turn into a net source.
"And of course we have the inconvenient truth that concentrations have been rising, giving us better crops, while the temperature has not been doing the same, as the models say it should. This suggests that CO2 concentrations actually do not drive temperature at all....""
Yet temperature has been rising. Temperature rise doesn't have to perfectly track the model predictions for CO2 to be a temperature driver. The weight of evidence is that CO2 is now the dominant driver given how fast we are increasing it.
