COP9 Side-Event Linking Article 2 & Article 6Experiences from a role-play of future climate negotiations with students from UCL Belgium, using the interactive Java Climate Model Jean-Pascal van Ypersele, Ben Matthews Micha Lauvau, François Beaumont, Philippe Marbaix, Sebastian Izquierdo, Sophie De Coninck, Mikael Ange Université catholique de Louvain, Louvain-la-Neuve, BelgiumContact:[email protected], [email protected] Institut d\'astronomie et de géophysique G.Lemaître, www.climate.be
60 university students grouped in 17 delegations(Belgium, Denmark, Russia, USA, Australia, Saudi-Arabia, Venezuela, Brazil, Burkina-Faso, Marroco, Tuvalu, India, Greenpeace, GCC, FAO, WB/IMF, Empêcheurs)had the task to agree by consensus:* a quantitative interpretation of Article 2, * an equitable formula for funding adaptation. Such experiments help to implement Article 6 and may also highlight science and policy questions for future negotiations (our role-play was COP-11).We will also discuss how to build on this experience, involving groups around the world.
(Any effective global agreement requires informed participation by many citizens. How to involve more people into the global dialogue?)
(Which dangerous climate impacts must we avoid, and with how much certainty? Hence, what is a safe level of stabilisation to avoid these impacts?)
Article 2 involves risk/value judgements, many stakeholders should participate.
\'...stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.
Such a level should be achieved within a time frame sufficient
- to allow ecosystems to adapt naturally to climate change,
- to ensure that food production is not threatened and
- to enable economic development to proceed in a sustainable manner.\'
(technologies, lifestyles, policy instruments)
Emissions pathways(biogeochemical cycles)
(global temperature / radiative forcing)
(regional climate changes)
Risk/Value Judgements (including equity implications):
Impacts: Key Vulnerabilities? Acceptable level of Change?
Risk: Target Indicator? Acceptable Level of Certainty?
(choice of target indicator shifts the burden of uncertainty)
Such risk/value decisions cannot be made by scientific experts alone.
The ultimate “integrated assessment model” remains the global network of human heads.
To reach effective global agreements, we need an iterative global dialogue including citizens / stakeholders. The corrective feedback process is more important than the initial guess. So let\'s start this global debate!
In preparing positions for the role-play, the students used the Java Climate Model to explore options and uncertainties.
By selecting parameters / indicators, same model can "justify" diverse positions

Final compromise between Russia and Tuvalu (after US quit)
Quantitative interpretation of Article 2: +Temperature rise (<1.9°C 2100-1990) + Sea-level rise (46cm 2100-1990)+ (Scientific inconsistency maybe realistic in policy compromises?)
Principles for Adaptation funds : +Tax on emissions trading + Percapita emissions & GDP formula + Principles sufficiency/capacity
“After this simulation of international negotiations, we discovered the great inertia and complexity that rule both the climatic and diplomatic systems, the latter maybe harder to model than the former. However we all felt that it was an original and exciting human experience”
Such web models might provide a quantative framework for a global dialogue.
Could we combine such tools and experience to link groups from all corners of the world?
