1. Workshop on Climate Change Impacts, Adaptation, and Vulnerability (IAV) Community Coordination 8-9 January 2009, National Center of Atmospheric Research (NCAR), Boulder, CO, USA Some thoughts on IAV community co-operation Timothy Carter Finnish Environment Institute, SYKE Research Programme for Global Change

2. Workshop on Climate Change Impacts, Adaptation, and Vulnerability (IAV) Community Coordination 8-9 January 2009, National Center of Atmospheric Research (NCAR), Boulder, CO, USA Who are we in IAV?  Empiricists Observed impacts (long-term/extreme events); observed adaptation (reactive and anticipatory; to averages/extremes; maladaptation)  Impact modellers Disciplinary/process focus (and ESMs); disciplinary/applied focus; inter- disciplinary/applied focus; integrated assessment; global to local  Experimentalists Gas enrichment; controlled climate; materials; land use management  Vulnerability assessors Mapping indices/indicators; local (household) to global  Adaptation researchers Adaptation processes; adaptation practices; management for adaptation and mitigation; development of analytical methods, tools and metrics  Adaptation policy analysts Governance; coherence; integration; mitigation/adaptation; implementation  Well, that's just some of us!

4. Workshop on Climate Change Impacts, Adaptation, and Vulnerability (IAV) Community Coordination 8-9 January 2009, National Center of Atmospheric Research (NCAR), Boulder, CO, USA What is the function of an IAV network?  To represent IAV interests in developing new scenarios?  To promote initiatives for IAV research co- ordination?  To develop structures for an international IAV research programme?  To link IAV to the wider, non-climate change research community?  Several or all of the above?

5. Workshop on Climate Change Impacts, Adaptation, and Vulnerability (IAV) Community Coordination 8-9 January 2009, National Center of Atmospheric Research (NCAR), Boulder, CO, USA Network to represent IAV interests developing new scenarios  Original motivating force behind this initiative  Main issues: Representing IAV needs in discussions about the new scenarios Providing a reference point/organisation for interacting with the climate modelling and integrated assessment modelling communities Ensuring that new scenarios are delivered that are appropriate and timely for IAV analysis and can be distributed to those researchers who require them – relationship to TGICA  2007 scenarios questionnaire to IPCC WG II LAs (response rate 15/39) – all supported new scenarios; stressed need for regional information and scenario "relevance" for stakeholders  Need for IAV co-ordination raised in Nordwijkerhout, Sep 2007  EC meeting on AR5 new scenarios, Brussels, Sep 2008 European research projects would benefit from co-ordination of scenario development, interpretation and guidance (e.g. including this network) But, unsuccessful request for supplementary EC funding for this meeting

6. Workshop on Climate Change Impacts, Adaptation, and Vulnerability (IAV) Community Coordination 8-9 January 2009, National Center of Atmospheric Research (NCAR), Boulder, CO, USA Network to promote initiatives for IAV research co-ordination  Co-ordinate IAV research efforts, for example: Basic research – process studies, empirical analysis, model development Impact/adaptation model intercomparison studies (viz. IGBP/GCTE, 1990s) Common issues (e.g. irreversibility; thresholds; costing; high impact events) Collection and collation of new information and studies on observed impacts/adaptations (incl. limits to adaptation, relationships to mitigation) Provision of models, tools, data and scenarios Development of guidance for IAV practitioners Workshops and conferences to exchange information and design new collaborative research Organisation of training courses, mentorships, workshops, targeting e.g. young researchers, developing country researchers, policy makers, planners  Enable more coherent and effective communication with other research communities and stakeholder groups?  Probably requires international steering and regional/sectoral representatives  Overlaps with IPCC TGICA (Task Group on Data and Scenario Support for Impacts and Climate Analysis)?

7. Workshop on Climate Change Impacts, Adaptation, and Vulnerability (IAV) Community Coordination 8-9 January 2009, National Center of Atmospheric Research (NCAR), Boulder, CO, USA Network to develop structures for an international IAV research programme  Develop a structure for the international co-ordination and funding of IAV research comparable to WCRP and focused on climate change as distinct from related programmes?  Attempt to re-invigorate UNEP's World Climate Impacts and Responses Programme (WCIRP)  Other options: WMO leadership; researchers' consortium; nationally-led initiatives (e.g. UK DfID)  Other related initiatives, e.g. WCC3 Conference (Geneva, Sep 2009), will establish a world climate information network  Earlier programmes: Country Studies; AIACC  Funding: ideally by governments

8. Workshop on Climate Change Impacts, Adaptation, and Vulnerability (IAV) Community Coordination 8-9 January 2009, National Center of Atmospheric Research (NCAR), Boulder, CO, USA Network to link IAV to the wider, non- climate change research community  Forge links to research communities outside the mainstream climate change research community (e.g. social vulnerability, sustainable development, governance, disaster management, natural hazards)?  Liaise with various user communities and stakeholders to co- ordinate effective IAV assessment and exchange tools, best practices, data and scenarios

9. Workshop on Climate Change Impacts, Adaptation, and Vulnerability (IAV) Community Coordination 8-9 January 2009, National Center of Atmospheric Research (NCAR), Boulder, CO, USA Three final observations  A network should be research/science – based  Basic and applied/synthetic research – is there a bias?  A single network may not serve all of our needs
