7. Regional Climate changes: Storm track variability and changes (E. Chang) Why are winter storms important? -- weather and regional climate -- transport heat and moisture poleward Impact of storm track changes: -- e.g. El Nino: Pacific storm track shifts southward: significant impacts on west coast climate Global warming model prediction: -- Storm tracks move poleward and intensify -- significant impacts on regional climate and hydrology

8. Issues: -- Reasons for such changes? -- How reliable are these predictions? Current model deficiencies: -- current climate models just resolving these storms -- physics: too strong coupling between moisture and dynamics? (Deficiencies in seasonal cycle) Fundamental science questions: -- what controls the location and intensity of storm tracks? -- Land sea distribution? Mountains? Heating? Methodology: -- Suite of high (1°) and lower resolution GCM simulations -- Novelty: -- diagnosed using a suite of diagnostic (statistical and mechanistic) models developed by the PI -- validation of analyses and GCMs using observations

16. MARKAL analyzes mitigation options for the entire energy system & can address adaptation Impacts, vulnerability & adaptation (IVA) approaches are difficult to analyze IVA effects are not yet comprehensively captured, including integrated assessment models (IAMs) Impacts, Adaptation & Mitigation: Missing Links (Reisman, Bhatt) *According to the IPCC AR4 WGII “technologies & strategies (for mitigation & adaptation) are known and developed”, but the “assessed literature does not indicate how effective various options are to fully reduce risks, particularly at higher levels of warming and related impacts, and for vulnerable groups.” Back to the Basics: Climate Change 101 Adaptation Systems Characteristics, Capacity to adapt Mitigation* Energy technologies, resources, Strategies Climate Change Science, Processes & Modeling Impacts & Vulnerability Magnitude & timing, Regional variations Avoided, Reduced or Delayed Diminish the Risks

17. MARKAL for Mitigation Analysis (Reisman, Bhatt) MARKAL Reference Energy System Integrated energy systems analysis model – bottom-up technology rich Analyzes environmental, technological and policy restrictions Facilitates devising optimal strategies for technology deployment based on life-cycle costs Signifies a flexible, transparent & well documented methodology Epitomizes scalability: Global, National, Regional, State & Urban variants On-going energy-climate related MARKAL applications include: President’s State of the Union address 2006 & Pre-Kyoto decision in 1997 U.S. DOE & U.S. EPA for GHG mitigation & impacts of DOE energy technology R&D on carbon and energy futures: GNEP, Renewable & Hydrogen, Energy-Water Nexus IPCC Scenario Analysis & G8 initiative – Gleneagles Summit 2005 MARKAL Overview
