An assessment of 'Contraction & Concentrations' and 'Contraction & Convergence' and the C&C targets and modelling behind rates of 'sink-efficiency' in the UK Government's 'Climate Act' [2008].
The '46:54' odds the UK Government gave against avoiding a temperature rise globally of more than two degrees with their emissions scenario are examined in this context. They are linked the Government's wholly unsubstantiated claim that atmosphere concentrations will fall after 2050 even though we are projected as only halfway through a 100-year emissions 'contraction-event'.

Presentation/Animation - C&C in the context of IPCC AR4 [2007] and the so-called 'coupled-carbon-cycle' modelling reported quantitatively for the first time since IPCC FAR 1990. Essentially, due to 'positive feedback' effects in the carbon cycle, where rising temperature amplifies the rate at which atmospheric GHG concentration increases, accelerated rates of carbon emissions contraction are needed to meet a given concentration outcome. This is the increasingly crucial issue of changing rates of 'Sink-efficiency'.

In depth analysis of this in relation to the UK Climate Act is here in this Evidence to UK Environmental Audit Committee.

Presentation/Animation and Notes


About future 'growth', you should ask an economist 'how long is a piece of string'.
H
e may tell you a witty Woody Allen one-liner about infinity being a really long time, 'especially towards the end'; [in other words he'll probably try and avoid the question].

If you ask a string-player how long is a piece of string, s/he'll give you a different answer.
S/he'll say: -

  1. exactly twice half its length' [giving the perfect octave]
  2. exactly three time a third of its length [giving the perfect octave]

as in the audio-visually animated image above.
This Pythagorean 'stringularity' true because it has 'ontological structure'.
