Due to revisions the spreadsheets of the C&C calculating model, they are unavailable at this time.

The Scenarios C1 C2 C3 animation here gives an indication of the model's use to compare various C&C scenarios.

The C&C Analysis for Minister HILARY BENN in the animation here gives another indication of the model's use to compare various C&C scenarios.

Contraction:Concentrations
For UNFCCC-compliance & assessing the risks of failure, we should measure Contraction:Concentrations in the same unit [Gt C].
Doing this shows that for public policy development, shrinking the 'Carbon-Emission-Budget' is more risk-averse than letting 'Atmospheric-Carbon-Concentrations' [ACC] rise out of control due to positive-feedback.
This means faster than predicted by mainstream IPCC.

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 '50:50' odds the UK Government gave for 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'.
