Essentially a 'tipping point'suggests a before-and-after moment when [if we actually do] we cross from 'equilibrium-seeking' behaviour to 'runaway behaviour'. In other words, before its a 'point', when we are projecting the future, it is a dynamic time line and the tipping-point is potentially somewhere on that dynamic time line.
Analysis of the UKMO's Integrated-Feedback [deceleration curves] versus the CBAT Segregated-Feedback [acceleration curves] shows vividly how easy it is to misjudge and unwittingly traverse this dynamic time line when feedbacks are omitted from the climate-model, as is the case with the climate model UKMO used to generate the UK Climate Act [UKCA] and the IPCC AR5 results.
In other words, by omitting key feedback effects in its climate model, the UKMO model falsely suggested that the UKCA is projected at rates which qualify as 'equilibrium-seeking' behaviour, when in reality UKCA is more probably projecting rates that take us into 'runaway behaviour' with uncontrollably rising costs and economic collapse, as shown in the CBAT DOMAIN FOUR Damages and Growth.
The essential dynamic of damages increasingly outpacing growth in proportion to slower contraction and higher concentrations is shown at 'button-9' of the C&C animation here. it was done for the DEFRA Minister Hilary BENN in 2007.
CBAT Domain Four will have integrated this dynamic with both the 'Integrated Feedback' and the 'Segregated Feedback' analysis, visible in all screens [centre or left] for all three budgets when the overall GUI is complete.
