Even for a system which is chaotic, paths through the parameter space do not necessarily fill the entire space and measures of the areas which are filled can be used to make future predictions.

The fact that climate scientists do not treat climate as a chaotic system demonstrates the futility of their research and the invalidity of their conclusions.

They do not attempt to predict or reenact the exact internal behavior of any preexisting system because a chaotic system is, by its very nature, unable to be duplicated.

Tomas, when you couple a chaotic system with random control - parameter variations (solar input, in particular, in the case of Earth) you do indeed get random, unpredictable responses (unless the control parameters are varied through some sort of feedback - loop to actually control the system — not relevant to this situation).

Characteristic of this school is the following quote: But as soon as you add any sort of noise, your perfect chaotic system becomes a mere stochastic one over long time periods, and probabilities really do apply.

Anybody not understanding those facts either do not understand the profound and mostly unknown complexities of the chaotic system or are paid to look the other way.

The movement of pressure systems is irregular both in latitude and longitude because of the underlying chaotic behaviour of the weather systems but move they clearly do.

In my opinion it is an unanswerable question and the use of the term anomaly is BS because it is a chaotic system that we don't even know what all the variables are.

Chaotic systems generally do not run out of control but have behaviours dominated by attractors.

The basic science, in terms of the feedbacks, is unproven because there is no repeatable empirical evidence, and because it relies on computer modelling of chaotic systems, which can not be done in a deterministic way.

I don't particuarly understand your point — that they use «slowing down» and «noisy bifurcation» rather than some unspecified other property of chaotic systems?

Once this done, and provided the dynamics has the ergodic property (a chaotic system may be but has not to be ergodic), one can apply the regodic theorem and study the probabilities of the different states.

If we have a chaotic system with two attractors where the choice of the attractor is not controlled by external forcing (like Milankovitch cycles) but by random factors then this does not work, but if the external forcings dominate in the choice then there are no problems of the type you indicate.

I do not «believe» in cycles or other such efforts to make sense of a chaotic system.

All of these chaotic systems you are desribing do not change the internal energy of the system and will only increase entropy.

The thing is, in chaotic systems, particularly markets where «positive feedbacks» are the norm, you don't really have a normal distribution of adverse events.

The best one can do with a chaotic (or quasi-chaotic) system is to identify a set of apparent oscillations and to extrapolate them.

I do think weather and climate clearly chaotic (as per fact, Lorenz and the rest), but I also think the time and effort being put into the forecasting of both suggest a lot of fine minds think useful prediction of this chaotic system possible.

Being chaotic, the system will oscillate, as we see it do at all scales of interest, but there is literally no reason to believe that the net effect of these oscillations will be warming.

The main evidence for catastrophic anthropogenic global warming (CAGW), the principal alleged adverse effect of human emissions of carbon dioxide (CO2), is climate models built by CAGW supporters in a field where models with real predictive power do not exist and can not be built with any demonstrable accuracy beyond a week or two because climate and weather are coupled non-linear chaotic systems.

As we have seen in part I and II of the series, low frequency - high amplitude climate change does not take place in a chaotic manner, but mainly through cycles, quasicycles, and oscillations that respond to periodic changes in the forcings that act over the climate system.

AMO / PDO on the other hand are system states that last 20 - 40 years, and there's very good reasons to think that they are the cause of the entire modern warming, these should be modeled by GCM's, but they don't do this either, and they have a far bigger effect on «climate» while the smaller scale chaotic artifacts have no effect on «climate».

Natural fluctuations don't quite average out (e.g. solar, ocean circulation regimes) because the system is nonlinear and chaotic and can be «poked» into shifting through an interaction of external forcing (natural or anthropogenic) and the circulations of atmospheres and oceans.

The resulting situation is in most cases stable as long as external factors do not force a change, but attractors of a chaotic system may give the impression of such stability.
