North America Regional Climate Change Assessment Program Global models do not have sufficient spatial resolution to provide climate information at scales needed for decision-making on adapting to climate change Use results of global climate models of future scenario climates as boundary conditions for regional climate models Develop scenarios of contemporary and future climate at spatial scales of 50 km for use in assessing impacts of climate change

Proposed new Midwest Consortium for Climate Assessment (Mi. CCA)

Midwest Consortium for Climate Assessment (Mi. CCA) Mi. CCA’s mission is to translate and enhance the latest NOAA climate forecast products to maximize economic gains for agricultural producers and their agribusiness service providers in the U. S. Midwest through use of advanced regional models, interactive web-based decision-making tools, and high-volume customized delivery and feedback through the existing integrated regional, state, and county level extension service network throughout the 9 -state region (MN, IA, MO, WI, IL, MI, IN, OH, KY).

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. CLIMATE SCIENCE INITITATIVE, IOWA STATE UNIVERSITY

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. CLIMATE SCIENCE INITITATIVE, IOWA STATE UNIVERSITY

ISU Climate Science Initiative Launched by Vice President Brighton Colleges of Agric, Engr, LAS have taken leadership, but broad campus research participation will be emphasized Build on research strengths in regional climate modeling, agriculture, water, landscapes, engineering CLIMATE SCIENCE INITITATIVE, IOWA STATE UNIVERSITY

Climate Science Initiative Vision: That Iowa State will be the leading US university in forecasting climate at regional scales with lead times of two weeks to multi-decadal for use in decision-making. A major component of the nation’s food supply and renewable fuel supply is vulnerable to both natural cycles of climate and changes due to increases in atmospheric greenhouse gases. Failure to anticipate major floods and droughts of regional scale will create profound shocks to the nation’s economy. Recent advances in forecasting global climate out to nine years by use global climate models initialized with new measurements of “ocean heat content” as reported in Science raise prospects for increased predictability on seasonal and longer time scales

Climate Science Initiative: Progress So Far Held informational meeting Nov 26 – 75 attended (additional 20 sent regrets) – 59 faculty, 16 staff/admin – 22 departments, 5 colleges Reported back to VPRED advisory team – VP Brighton, Deans Wintersteen, Whiteford, Kushner – Approval to move forward – Hired web master, invite speakers Forming Climate Science Initiative Council Forging linkages with other programs
