These small alterations are taken into account in climate models, with the average of all models (i.e. an ensemble forecast, a term you should know well as a former meteorologist), scientists (like those at the IPCC) can arrive at a sensible estimate of what we are likely to experience in the future.
The scientific community has also known for some time that the predicted future global warming in most climate models (more than 2 degrees C.) would probably be well above the long - term average temperature present at any time during the Holocene.
Unfortunately, the figure also confirms that the spatial resolution of theoutput from the GCMs used in the Mediterranean study is too coarse for constructing detailed regional scenarios.To develop more detailed regional scenarios, modelers can combine the GCM results with output from statistical models.3 This is done by constructing a statistical model to explain the observed temperature or precipitation at a meteorological station in terms of a range of regionally - averaged climate variables.
Tom, If you accept that the pauses, previously occurring and the one at the present, are part of long period cycles whose long term average is related to the actual long term trend of temperature (rather than the far steeper slope of rise from just 1980 to 1999), you are admitting that the rise (from whatever cause) has a slope of closer to 0.4 C per century than the super inflated values of 2C to 6C per century claimed by the models and supporters of CAGW.

As you can see, over periods of a few decades, modeled internal variability does not cause surface temperatures to change by more than 0.3 °C, and over longer periods, such as the entire 20th Century, its transient warming and cooling influences tend to average out, and internal variability does not cause long - term temperature trends.

In a system such as the climate, we can never include enough variables to describe the actual system on all relevant length scales (e.g. the butterfly effect — MICROSCOPIC perturbations grow exponentially in time to drive the system to completely different states over macroscopic time) so the best that we can often do is model it as a complex nonlinear set of ordinary differential equations with stochastic noise terms — a generalized Langevin equation or generalized Master equation, as it were — and average behaviors over what one hopes is a spanning set of butterfly - wing perturbations to assess whether or not the resulting system trajectories fill the available phase space uniformly or perhaps are restricted or constrained in some way.
