Chaos theory certainly is important for the field of climatology. The very notion of a stable system making a sudden phase change to a new stable system owes much to chaos theory. My understanding of current climatology is that we are in the middle of a phase change to a new and more hostile climate caused by the sudden input of CO2 into the atmosphere.
Chaos Theory was born out of climatology. It was discovered while scientists were, yes, attempting to predict weather. That was when they discovered that it was impossible to predict beyond a few days, maybe a week, and even then the forecasts are often wrong. Indeed, even short term weather forecasts are rarely, if ever, 100% accurate. Ask a meteorologist to predict what the weather in any city in the world will be like on November 3rd (for instance) 2013. They can't do it. They can perhaps give a "temperature range" based on the PAST history of the region, but ask them to put money on a precise prediction, such as, "Will it rain that day" and they'll balk every time.
Again, the idea that a dynamical system's "phase change" can be PREDICTED at all flies in the face of Chaos Theory, by definition. Even if we had developed a perfect set of equations to model future climate behavior (which we have yet to do) -- but, even if we had a perfect model, we would still require 100% precise mathematical values to enter into those perfect equations to properly represent exact INITIAL CONDITIONS -- otherwise the resultant outcome will be randomly flawed. Imagine the sheer volume of 100% precise data that would be necessary to enter into such equations in order to have a glimmer of possibly making an accurate prediction. It is astronomical in scope.
Last year I posted a very long list of extremely hostile climactic events that occurred prior to the increase in CO2 of recent decades. It was quite extensive...and revealing. I have seen no evidence that current climactic hostility exceeds the climactic hostility of pre-high CO2 levels.
