Jan 5 2013: C&C [or "Contraction and Convergence"] is one part of an integrated four part concept-constitution.
The first 'domain' of this is 'Contraction and Concentrations'. Here, simply put, the question is what global total of future emissions is consistent with a safe and stable concentration outcome and thus achieving compliance with the objective of the UN Climate Treaty [UNFCCC].
Then - Domain two "Contraction and Convergence" and domain three "Contraction and Conversion" options are computed as a function of the result obtained in the first domain calculation.
The overall result is then tested against Domain four "Damages and Growth". This means the whole exercise is about "Precaution" and "Prevention" and analysing to ensure that we are 'doing enough soon enough' to make it worth the effort [as doing too little too late is obviously not].
What is optimal is achieving UNFCCC-compliance.
What is not optimal or ever going to be, is continually trying to achieve UNFCCC-compliance based on keeping the cart of growth in front of the horse or prevention, as a way of sustaining confusion and indecision by provoking conflicting ideological opinions about urgency and equity.

A reply on Conversation: Imagine a scenario this century that is very bleak for agriculture. What do you think we should do to address humanity's thrivability?
