[1] stave off the positive feedback accelerator that we now step onto and [2] subject to requirement one, pre-allocate rationally under that contraction limit at a convergence rate which is an acceleration relative to one but an agreed compromise between those who argue for ’slow-late’ versus those who argue for ‘fast-soon’.

Haas repeats Stern’s new argument that C&C is a “spectacularly weak form of justice” – indeed citing [what for me is] a spectacularly weak form of C&C.

Mr Stern is clearly mentally challenged by the issue of accounting climate change mitigation with C&C, as this fundamentally reverses Mr Stern’s opinion of C&C for a third time in one year.

His much vaunted report, dismissed C&C as an ‘assertion’ [not an argument] and then asserted the preposterous viuew that 550 ppmv atmosphere concnetration of CO2 can be achieved for a mere one percent of GDP. [The damages from climate change will overwhelm this account within decades - it is too little too late].

Stern then went on to tell his students that C&C as equal rights was, “too difficult to get your head around”.

He then went on [only weeks ago in Potsdam] and signed the nobel-laureate statement [below] asserting the: -

” Principle of carbon justice, i.e. striving for a long-term convergence to equal-per-capita emissions rights accomplished through a medium-term multi-stage approach accounting for differentiated national capacities.

Mr Stern has been poorly advised and – like Mr Haas and his climate-equity clique – has not done his own homework adequately.

The C&C calculus is clearly laid out here against the backdrop of the ‘coupled model’ runs from the Hadley Centre now in IPCC AR4: -

This shows the narrowing opportunity we now face and is the basis of any globally numerate response to climate change.

• Global target such as the 2°C-limit for planetary warming relative to
pre-industrial levels or the (largely equivalent) halving of worldwide
greenhouse emissions by 2050. It is useful to view those emissions as
the product of two crucial factors, namely per capita emissions times
population. Both of these must be appropriately addressed to attain the
long-term stabilization target.

• Series of consistent short and medium-term emissions reduction
targets, essential to drive investment and technology and to minimize
the need for greater action later.

• Leadership role of industrialized countries, both regarding drastic
emissions reductions and development of low/no-carbon technologies in
order to give poor developing countries room for urgently needed
economic growth within the boundaries of a global carbon regime.

• Principle of carbon justice, i.e. striving for a long-term convergence
to equal-per-capita emissions rights accomplished through a medium-term
multi-stage approach accounting for differentiated national capacities.

• Carbon price, as generated, for instance, through an international
cap-and-trade system (of systems) based on auctioning permits.

• Establishment of a powerful worldwide process supporting
climate-friendly innovation and cooperation, combined with increased
funding for RD&D including basic research, to facilitate technology
transfer and proliferation.

• Major contributions to a multinational funding system for enhancing
adaptive capacities.

• Scaled-up efforts to reduce emissions from deforestation and
accelerate ecologically appropriate reforestation, achievable through
the creation of new incentives for communities and countries to preserve
and even increase their forests.

• Reductions of non-CO2 greenhouse gas emissions.
