Sensitive dependence on initial conditions. Complex systems defy specific predictive modeling. But the things that climate models can do and have done is show: Climate change is caused by human emissions of greenhouse gasses. It will be bad. We’re reaching several tipping points where runaway reinforcement cycles will accelerate the damage. (Eg, temperature rises in the arctic melt permafrost releasing methane from the resulting boggy ground which is a powerful greenhouse gas, which causes warming which causes more melting GOTO 1)
