The first question that has to be answered before taking questions about financial flow-rates is: “What weight and rate of non-human feedback emissions is now projected as a result of the delay in the control of non-feedback human emissions from the fossil economy?” Consequently and in the light of that answer, the second question that has to be answered before taking questions about financial flow-rates is: “What weight and rate of carbon-contraction:concentrations is still consistent with UNFCCC-compliance [safe and stable GHG concentration]?” The third question that has to be answered before questions about taking financial flow-rates is: “What straightforward principle will this [by definition] international contraction:convergence event be shared globally? The numeraire of the answers to these questions is Gt C; first and foremost it is measured in tonnes of carbon emissions and entitlement to those emissions. It is not first and foremost in dollars. Whatever the quantum of dollars is that is deployed to the purpose of UNFCCC-compliance, it is dollars per that quantum of those tonnes only and not per more than those tonnes. Since the quantum available now for that purpose is now very limited e.g. an event weighing not more than 200 Gigatonnes and reaching zero emissions globally by 2050 needs to agreed. Even then there remains the risk that the contraction-rate will be over-taken by non-human feedback emissions from melting permafrost to name but one example. With this feedback alone, there are at least two trillion tonnes of carbon latent in the soils that start now to melt and gradually to make them patent as but one contribution to the non-human feedback emissions that threaten to overwhelm us. http://www.gci.org.uk/images/Perma_Frost_Melt_Carbon_Release_a_a__%20copy.pdf
