Space Scales: subtantional; national; regional; global
A. CLIMATE DYNAMICS All time scales: primarily global space scales currently (GCM's). Limited regional capacity (patchy). B. IMPACTS: BIOGEOCHEMICAL SYSTEMS (BGS) 1) Climate impacts on BGS. 2) BGS impacts on climate. 3) Feedback loops and natural variability (mediated via the Enso cycle). C. IMPACTS: SOCIOECONOMIC/POLITICAL SYSTEMS (SS) 1) Climate impacts on SS (focus on sensitivity and vulnerability). 2) Anthropogenic impacts on climate. 3) Feedback loops and time lags (mediated via the ENSO cycle). D. THRESHOLD EFFECTS: BGS/SS 1) Climate on BGS/SS. 2) BGS/SS on climate. 3) Rates of change. 4) Ecosystemic and distributional effects. 5) Sensitivities and vulnerabilities (mediated via the ENSO cycle). E. SOCIOECONOMIC/POLITICAL RESPONSE STRATEGIES 1) Type and value of forecast products. 2) Timing of forecasts (will vary by type of use). 3) Institutional contexts and constraints. 4) Planning, adaptation, & mitigation strategies. 5) Probable outcomes and effects for forecast scenarios.
