Patrick said:You seem to have surrendered "proof" and fallen back to the "overwhelming evidence" trench.
So it is for much of science, that doesn't invalidate much of it, it just means you have to give a margin of error for your predictions.
The standard of proof is nothing other than using unquestioned, verified facts from credible sources, and applying to them the methods of induction to show that they necessarlily imply the conclusion that industrial processes etc cause at least a substantial portion of global warming.
You are exactly correct that you can't have a model world in a test tube - and that that's what makes it so difficult to prove. And that's why it hasn't been proven, it's extremely difficult or impossible to prove.
As for simulation, I've been involved in that in the past, e.g. stellar interior models of stars, or in the aerospace industry models of contained plasmas and nuclear burn codes. (I also worked in discrete event simulation.) In my experience, such simulations require the simultaneous solution of differential or integro-differential equations. Everyone who has been involved with this type of work knows that the solutions obtained can be very sensitive to the constants and boundary conditions used - let alone whether the equations used are a near correct and complete model. Sometimes they can be extremely sensitive. I remember seeing an animated film that showed the wide variety of results in number and distribution of sizes of planets in the solar system, employing the standard Descartes/Kant model and tweaking a few parameters slightly. Sometimes people make simplifications motivated only by lack of computer power (and "lack" can mean not a sufficiently large array of supercomputers).
In plain english, if you lack integrity it's easy to "get" the result you want, and impress the uniformed with a lot of scientific terms, charts, and other decoration.
If we have now left "proof" behind, I am not convinced there is "overwhelming evidence" - I think there is overwhelming propaganda. Note that I said that what they say may turn out to be true - I just don't think there has been any demonstration of that.
What I'm very convinced of is the economic destruction that the Kyoto treaty would cause the U.S., and its basic unfairness.
They have demonstrated their models explain the known world, it is a fair guess that they will predict the future climate. Don't forget, climate predictin is not weather prediction.
But you have no 'proof' that this would happen, do you?
Think about this: everything that isn't purely spiritual depends on economics. Think what you are doing when you adopt an economy destroying treaty based upon unconvincing science: you are lowering the standards of living for everyone. You are taking money away (obtained from tax revenues and contributions) from scientific research on diseases. You are taking away from the arts. You are taking away from money to help the poor. You are taking away from the level of medical care and how much can be done for the aging. You are taking away from education.
BS. Much economic activity is just turnover on non essential items. Directing some of that activity to conservation is not going to be the end of the world.
The question for YOU is, are you so sure about the warming evidence that you are willing to support policies that for certain have all the effects I decribed above, and more?

All of a sudden, you know for a fact that this is what will happen. Now, what proof do you have.
