I just found this post in the wrong mail folder and realized it went private to Rick instead of to vortex as intended.

Chaos and complexity are two separate and unrelated characteristics.

Well, they're separate anyway. A chaotic system could be very simple and
still have very complex outputs. Or it might have simple and much more
predictable outputs. Depends on the structure, but not necessarily the
complexity, of the system. As you said, they're different. A chaotic system
could also be very complex and have relatively simple and predictable
outputs. The claim that the global climate has those characteristics is
false to a high degree of certainty given historical records.

This is all related more to the *perception* of global warming and the accuracy of shorter term specific models.

A pot of water on a burner takes in heat from the burner and gives heat to the environment by various means, including conduction, convection, and radiation. The water in the pot exhibits chaotic behavior, especially in its convection patterns, which are described by differential equations, and have characteristics similar to the atmosphere. For example, it is quickly impossible to predict the location of a single neutral buoyancy pea in the water. The fact the convection is difficult to model and predict, and a crucial element to understanding precisely how the heat transfer of the pot is working, is a red herring argument with respect to whether it is possible to predict approximately the longer term behavior of the average temperature of the pot and when it will boil dry.
