False. Then why did the prediction of Florida being underwater not come true? Why do we still have snow?
Even the current climate models are run with full knowledge that there are at least more unknowns than knowns. And then there is the absolute fact that changing the known variables to anywhere within the range of uncertainty can produce warming or cooling predictions. A model that tells you two opposite answers is useless for predictions.
If you actually think the climate is simple enough to be understood with our current knowledge, then you have no understanding of the climate's complexity.
We can not accurately forecast weather more than 10 days out even with a very hi-res GCM because weather is chaotic. The analogy is a butterfly in Spain causing a hurricane in Florida.
Thank you for admitting this!
And the problems with the averages is that we dont know about the butterflies in the past, because we only have an extremely low resolution record of past conditions. And actually, we dont even track those butterflies in the present, and can only speculate on the ones we are not taking into account. - more unknowns than knowns.
