Severe climate changes during the last ice - age could have been caused by random chaotic variations on Earth and not governed by external periodic influences from the Sun.
The existence of D - O cycles appear to demonstrate that the climate is sometimes in a «base state» from which it will be chaotic (unless D - O cycles are actually rather more deterministic than generally thought).
Any state of the art climate model (CGCM) under stationary forcing (plus annual cycle) will eventually demonstrate some sort of chaotic behavior and / or will drift away from the realistic description of the actual atmosphere.
Since these processes, radiation and conduction, are not chaotic, where would chaos come from in climate?
I still do not correctly understand how the calculation of CO2 sensitivity in past or present climates can be independant from the estimation of the other forcings related to temperature trends (and from natural / chaotic variability).

«Ben Santer [federal climatologist] just published a pal - reviewed paper in the Proceedings of the National Academy of Science loudly proclaiming that the dreaded man - made global warming signal has emerged from our naturally chaotic climate... pretty much what he wrote in Naturefor the UN's 1996 edition of this conference, 16 years ago.
«In particular, it is not obvious, as of today, whether it is more efficient to approach the problem of constructing a theory of climate dynamics starting from the framework of hamiltonian mechanics and quasi-equilibrium statistical mechanics or taking the point of view of dissipative chaotic dynamical systems, and of non-equilibrium statistical mechanics, and even the authors of this review disagree.
Using error - propagation the way it is done here shows precisely the same mistake that seems to appear in a lot of climate models, a false assumption of linearity, starting from some conditions in a system that is physically strongly non-linear and numerically chaotic.
-- such a model would quickly depart from the unfolding climate found on Earth because chaotic systems defy prediction.
I take it from your post that you strongly believe the earth climate is a spatio temporal chaotic system?
Intuitively, the models seem to be running hot because (a) their climate response rate to doubling of CO2 is too high and (b) they do not adequately allow for negative feedbacks from clouds, among other influences which must remain beyond the realm of prediction due to their chaotic nature.
Actually supposing the climate is somehow chaotic one perhaps shouldn't expect a good fit from time - series models driven by gaussian noise.
In 2007 Dr. Anastasios A. Tsonis et al. approached the complexity of the climate system from the position that it is chaotic and proposed a whole new theory to explain climate shifts.
The intensity of our desire to find the driver of earth's weather and climate seems to pull us away from appreciating dynamic or chaotic systems and disenables us from the pleasure of understanding fundamental conditions.
We're overdue for a few paragraphs on chaotic climate from Ellison and mebbe time for BBD to spin the dial and pick out another talking point from Skeptical Science to cut & paste or is Science of Doom's turn?
A very comprehensive demolition of the alarmist conclusions drawn from very inadequate modelling of what is a chaotic and still poorly understood Earth climate system.
Chaotic influences from oceans and volcanoes etc. makes both weather more unpredictable and creates the unpredictable part of the «wiggles» around the average trend in climate.
So in a dissipative - chaotic system like climate, it is not surprising that the time wavetrain of climate status looked at from numerous metrics, will show emergent periodic structure and complexity.
The difference between an aggressive stance on climate change and a slower path could mean the difference between an orderly approach to sea level rise and a chaotic retreat from the coasts.

In fact, when viewing the future projections from the CMIP5 model, one sees the exact same pattern as above - a monotonous upward saw - tooth pattern of small ups and downs, completely unlike the chaotic conditions of real - world climate that is produced by all the conflicting natural feedback forces.
Nature provides only one single realization of many possible realizations of temperature variability over time from a whole distribution of possible realizations of a chaotic system for the given climate conditions, whereas the ensemble mean of models is an average over many of the possible realizations (117 model simulations in this case).
Proof can be easily found in various «discussions» about «chaotic» versus «predictable» climate, e.g.: http://www.realclimate.org/index.php?p=228 http://www.realclimate.org/index.php?p=204 http://www.realclimate.org/index.php?p=193 With exception of weak opposing voices like «Sashka» and Prof. Pielke, most participants have really little to no idea about the subject, starting from topic originators.
