1. ISU Climate Science Initiative Meeting objectives: *To assess the level of faculty interest in research relating to climate science at ISU *To identify opportunities to build partnerships at ISU between climate science and programs in bioeconomy, plant sciences, cyberinfrastructure, and climate-sensitive areas of research in agriculture, water resources, natural systems, and engineering for establishing ISU as a regional/national leader in climate science and impacts of climate change.

2. Intergovernmental Panel on Climate Change (IPCC) Established in 1988 by World Meteorological Organization (WMO) World Meteorological Organization (WMO) United Nations Environment Programme (UNEP) United Nations Environment Programme (UNEP) Supports the UN Framework Convention on Climate Change (UNFCCC) First Assessment Report - 1990 Second Assessment Report - 1995 Third Assessment Report (TAR) - 2001 Fourth Assessment Report (AR4) - 2007 Plus: special reports, technical papers, methodology reports and supporting material.

5. (IPCC TAR, Ch. 1) What is a climate model?

6. Options: Global model Global model  resolve continental scales  simulate 10s-100s yr Regional model Regional model  resolve broad human scales (river basins, agricultural zones, etc.)  simulate 10s-100s yr How can a numerical model represent all of this?

7. Example Regional Model Domain

8. North American Regional Climate Change Assessment Program (NARCCAP) An international project to evaluate regional climate change for North America. Uses nested regional climate models: fine-scale models that use results of coarse global models as input. –How does uncertainty propagate from global models through regional models? Develop multiple realizations of regional climate change for use in climate change impact assessment (patterned on global model data for the IPCC Fourth Assessment Report).

11. Seasonal Forecasting (MRED project) Weather forecasting is short-term (few days to 2 weeks) Climate projection is for decades Seasonal forecasting has had less attention, despite practical needs: –agriculture, construction and repair, transportation, etc.

12. Seasonal Forecasting (MRED project) MRED project is patterned after NARCCAP: –uses output from the National Centers for Environmental Prediction (NCEP) global model as input to fine-scale regional models –many of the same participants as NARCCAP ISU has done some exploratory work using a similar approach. Project has been proposed to NOAA.

13. Examples of Studying Impacts of Climate Change Global climate models have demonstrated skill in simulation of future climates (1980s GCMs projected accelerated warming in the Arctic that now is being observed) Regional model output is being used for studying Impact on land-use and climate change on landscape change (C. Kling, CARD) Impact of climate change on streamflow in UMRB (C. Kling, P. Gassman, M. Jha, CARD) Impact of climate change on tile drainage flow (A. Kalieta, M. Helmers, A&BE) Changes in wind speed (wind power) under climate change (S. Pryor, Indiana U) Pavement performance under climate change (C. Williams, CCEE) http://www.rcmlab.agron.iastate.edu/

14. Examples of Studying Impacts of Climate Change Regional model output is being used for studying Seasonal climate forecasts (MRED: J Roads, R. Leung, C. Anderson, H. Juang) Impact of climate change on crop yields (Z. Pan, SLU) Impact of climate change on plant disease (X. B. Yang, Plant Pathology, and Z. Pan) Others?
