Everyone has an opinion, but time for disbelief is over MisterS. You think maybe the emissions trading schemes are a waste of time or perhaps some sort of Al Gore inspired conspiracy to somehow tax businesses higher than they are now? Why would any government or institution even contemplate such a thing if there were any debate left to be had?
The greenhouse thing is there to try and point out to people that CO2 is a known greenhouse gas and if you increase the concenbtration by 50% in the atmosphere then, all else being equal, it is going to have an effect. Yes, the concentrations are very small and yes the temperature increase is only very small (a 2 degree rise is only 0.7% when measured in degrees Kelvin!) but the impact is very high.
Let me turn it around. Are you saying an increase of 50% in the concentration of CO2 in the atmosphere will have no discernible effect on the temperature of the atmosphere? Yes I know there is a multitude of variables that affect the temperature, but forget about them, I think we should stick to CO2 because that is what we are discussing here. You seem like an intelligent person. I am asking you about a 50% increase in CO2. Please tell me if you think it will affect the temperature, given that CO2 is a known greenhouse gas? No denigration, no abuse from me, please just answer the question. A simple yes or no would be great. Thanks.
Your link points out the inherent variability of climate modelling. I doubt anyone is going to disagree with that.
Oh, and this is not meant to be derogatory, but all theories are open to question. There is still a flat earth society.
