Info point 3: - CONCENTRATION PATHWAYS

Use of the 'Slider' shifts concentrations through 40 positions upwards and 40 positions downwards from 'zero = CAF 50'. So it is concentration-pathways 2010 to 2110 that emerge and that are shown as above and below CAF 50. At some fraction of emissions, these concentration-pathways are the accumulation of the underlying carbon-budget-integrals chosen across the years 2010 to 2110.

However, these pathways also include the advent of non-human [non-budget] 'feedback-emissions'. Combined together, these concentration-pathways have momentum. Once established, these will not just suddenly change direction or disappear. They will 'persist'.

So precautionary climate-policy indicates we should avoid getting on a concentrations-pathway that is high enough to develop a life of its own, in other words where self-propagating positive-feedback effects take over and make human efforts at mere emissions-mitigation futile.

CBAT user-choices of [a] budget, [b] slider-position, [c] feedback-type and [d] climate-sensitivity level [1-5] with all the resultant 'clock-values' on display, are presented to help connect users with the ranges of budget-choices and the increasingly possible and dangerous consequences of doing too-little too-late to control human-emissions.
