Lorenz’s study was of a simplified system, and still even that could not be predicted.
he eventually made an even more simple math model, a system of three equations (retaining the nonlinearity).
Graphing it gives the famous Lorenz butterfly.
Heh heh heh... and of course the earth is infinitely more.
These chaps are reading the climate as though its response were unidirectional and linear. The Gaia-worshipers almost have a better intuition on the situation because a living system has a will. In fact, a Creator who does have a will is superintending the situation.
