  1. DIVA-GIS & Climate Data Robert J. Hijmans International Rice Research Institute, Los Baños, Philippines

  2. DIVA-GIS • Biodiversity • Free • Simple to use • Demand driven development • Version 5.2 • http://www.diva-gis.org

  3. Data exploration

  4. Patterns of diversity and turnover

  5. Geo-Cluster

  6. Model Species Distribution

  7. Modeled: Future climate Modeled: Current climate Known Distribution

  8. www.diva-gis.org - program, manual, and data

  9. Climate Data • ‘Current’ climate • CRU-TS • WorldClim • Future climate

  10. Estimates of current (past) climate

  11. Precipitation (mm) Temperature (°C)

  12. ºC / year Temperature change during the 20th century CRU-TS

  13. ºC / year Temperature change during 1985-2002

  14. Future climate: GCMs David Viner, CRU

  15. Future climate: GCMs Different models: HADCM, ECHAM, CCCMA, CSRIO Different scenarios ISO92, IPCC SRES Spatial resolution

  16. Different models, different results CCMa HADCM ECHAM GFDL Change in mean annual temperature (°C) SRES A2

  17. Emission scenariosHadCMmodel A2a B2a Change in mean annual temperature (°C)

  18. Duffy et al. LLNL

  19. Statistical downscaling, “delta method” Temperature change Current climate Downscaled & calibrated future climate
