Models for calculating contributions to climate change

• Java Climate Model
  This interactive climate model lets you explore the climate system simply by moving controls with your mouse and observing the effect instantly on plots ranging from greenhouse gas emissions to global impacts. The calculation methods are based on those used in the recent Intergovernmental Panel on Climate Change Third Assessment Report, implemented efficiently in the java language to work within your web browser. The attribution module allows the instantaneous calculation of contributions to climate change of different regions.
• Framework to Asses International Regimes for differentiation of commitments (FAIR)
  This decision-support tool was developed with the aim of assisting policy makers in evaluating different options for differentiation of future commitments at the National Institute of Public Health and the Environment (RIVM), in The Netherlands. FAIR is an interactive - scanner-type - computer model that can be used to explore a range of alternative options for international differentiation of commitments in a quantitative way and link these to targets for global climate protection. It includes a case, where the Brazilian Proposal is implemented on a global scale. It is available for download at the FAIR web site.
