By the University of Southampton A decline in atmospheric carbon dioxide (CO2) levels led to a fundamental shift in the behaviour of the Earth's climate system around one million years ago, according to new research led by the University of Southampton.

The lower screen manages climate control and Terrain Response, the system that tailors the Range Rover Velar's behaviour in various off - road scenarios.

This is OK when you can completely control the replicability of a situation (eg changing the CO2 in a glass bottle) but rather more difficult in the case of the planet you are living on, when the inferences have to be made on the basis of both what happens in a glass bottle (physics) and what the observed behaviour of the unique subject (the planetary climate system) has been in terms of recent observations and its geological history.

Often these correlations mysteriously change phase with time, which is usually described as evidence of the non-linearity of the climate system, but in fact is the expected behaviour when there is no actual coherence.

The climate system as a whole is one of those topics where complexity is intrinsic, and while the behaviour of simpler systems or subsystems is fascinating, one can't avoid looking directly at the emergent properties of the whole system — of which the actual temperature changes from month to month are but one.

That the climate is main unpredictable and that is behaviour is best modelled as a chaotic unpredictable system with small predictable perturbation.

The climate modeler, on the other hand, is not interested in the system's behaviour at a particular point in time.

The ocean - atmosphere climate system is certainly a complex system, and capable of some surprising behaviours, but there is no evidence that it is chaotic in the formal sense.

«A dynamical system such as the climate system, governed by nonlinear deterministic equations (see Nonlinearity), may exhibit erratic or chaotic behaviour in the sense that very small changes in the initial state of the system in time lead to large and apparently unpredictable changes in its temporal evolution.

The Rossby Centre pursues research on climate processes and the behaviour of the climate system.

The start point is that C20th climate behaviour can not be explained adequately unless the climate system is responsive to radiative forcing.

Obviously the climate system is incredibly complex and full of unknowns — but taking a physical basis and making simplifications and assumptions can have predictive power over long term average behaviour without being perfect.

As an outsider, one is struck by how difficult it is to perform a formal experiment in climate science, yet the question of feedback demands experiments, as opposed to models, to identify critical system behaviours.

The richness of climate data behaviour, «decade by decade and century by century, testifies to the fundamentally chaotic nature of the system that we are attempting to predict.

I take the quote seriously — there are people out there who do «hope» that we are in the midst of sundry climate - linked crises, some manifesting already, others building up in the system to whack us later, The macabre claiming for their own purposes, each and every newsworthy piece of bad weather or related adverse events, is part of this peculiar, profoundly irresponsible behaviour *.

Rather than attack Tom you should see him as an example of climate scientists of all persuasions who are trying to analyse the behaviour of complex chaotic systems by the application of simplistic relationships studied in a laboratory.

Our collective cognitive belief systems and the resulting behaviours they engender will play pivotal roles in our failure or success in mitigating and adapting to the vast challenges of both Peak Oil and Climate Change.

In the case of global climate no unprecedented climate behaviours are observed so the Null Hypothesis decrees that the climate system has not changed.

Michael Chriton posed the question «if we can not acurately model the stock market to the point we can predict it's behaviour, what makes us think we can model a far more complex system, being the climate».

The most characteristic behaviour of the Grand Climate System is relatively stable states punctuated by abrupt shifts that owe more to internal dynamics of the system as a whole than external factors such as greenhouse System is relatively stable states punctuated by abrupt shifts that owe more to internal dynamics of the system as a whole than external factors such as greenhouse system as a whole than external factors such as greenhouse gases.

The UK's silent consensus to talk about climate — at some later date — simply means those choices will be made without debate, as though huge changes to our infrastructure, buildings, equipment, behaviours and food system can be delivered by a few technocrats working under the radar.

It is perhaps excusable that you can't get your head around the physical behaviour of the climate system, but that doesn't mean that everyone else who has studied it is a moron who is missing your supposed insight.

A system - dynamics model that couples a psychological model of behaviour with a model of emissions and climate change shows that behaviour can influence global temperature in the year 2100 by up to 1.5 °C.

If you imagine into existence a model that has zero sensitivity to CO2 but which otherwise simulates every directly observable behaviour of the earth system in perfect detail, then sure, we might well consider that the climate system sensitivity could be zero.

Non-linear behaviours are much less predictable and several factors increase the non-linearity of the climate system as a whole, thereby decreasing the predictability of climate systems in general.

But what is * not true * is the belief that the climate system * now * is capable of internally - forced behaviour that explains modern observations.

The problem is multiplied by having to explain the behaviour of complex, multi-factorial systems, and their inherent uncertainties, all of which are well exemplified by our climate.

Both climate - change deniers and climate - change alarmists are wrong on their claims about the implications of this [Northern Hemisphere] winter and how they interpret the behaviour of the earth's climatic system over the past 2000 years.

climate sensitivity is provided as a range of estimates due to underlying uncertainty in the behaviour of some aspects of the climate system as the planet warms.

A major limitation is the fact that the calibration phase for these semi-empirical models does not cover the range of climate - system behaviour that might be expected for the 21st century, i.e., significant loss of ice from the large polar ice sheets.

The climate system has many physical feedbacks which will lend to the creation of possible oscillatory behaviour.
