WCIAS Strategy
• Filling critical gaps in weather and climate
impact assessment science
• Developing integrating methodology
• Moving toward decision-making as a
centerpiece
• Promoting integration of assessment science
activities at NCAR, nationally and
internationally
Overview
• Decision-making in the WCAI
– An Evolutionary Perspective
• Moving Toward Decision-Making as
the Central Focus
• DUST
• Future Directions
Evolutionary Perspective
• Intentions:
– Produce science of high societal value
– Make uncertainties in weather/climate
assessments more transparent to decisionmakers (quantify, characterize, communicate)
– Assess the feasibility of an end-to-end
characterization of uncertainty (i.e., from
global climate model to decision-making)
• From providing decision support to also
examining the decision process…

(Assessment of needs,
decision entry points,
institutional constraints,
politics etc.)
For WCIAS projects where decision-making matters….
Adaptation
DUST – The Decision Uncertainty
Screening Tool
• Purpose
– Integrative link between physical sciences,
uncertainty analyses, and decision- and
policy-making
– Procedure to identify where and how science
can most effectively support decision-making
– Systematic approach to determining where
and when uncertainty matters
DUST – A stepwise, iterative attempt at improving the
science/decision-maker interaction
• Premises
– Decision-maker and decision-making are central
– Scientific information can be an important input into decisionmaking
– No assumption about best way to make decisions under
conditions of uncertainty
– No preference for a “top-down” or “bottom-up” approach to
assessments
• Objectives
– For all kinds of decisions
– For a variety of decision-making contexts
– For a range of decision-makers
– Applicable at a variety of scales
Step 1: Identify the stage in the decision
process where climate science can enter
Step 2: Ensure that scientific input is
useful, credible, and legitimate

Usefulness
- Relevance
- Compatibility
- Accessibility
- Receptivity
Decision-making
Step 3: Identify the type of decision
problem decision-makers face
OPTIMIZATION – EVALUATION – ROBUST ADAPTIVE PLANNING
Step 4: Identify the specific decision
challenge
A three-dimensional typology of climate-sensitive decisions
- Optimization/Evaluation
- Near-/Long-term
- One-time/Sequential
Step 5: Identify necessary uncertainty
analyses
Step 6: Conduct identified uncertainty
analyses
Step 7: Communicate uncertainties back
to the decision-maker
• Familiarity
• Format
Coordination
• Link back to decision
problem
Accuracy
• Explanation of
Wrong information
may be worse
uncertainties
than none at all
Keep others informed of what
they need to know, without
overburdening them with
unnecessary information
Good
Communication
Information
Who needs
to know what
Timeliness
Confirmation
Avoid confusion by
delivering message/
data on time
Make sure they right
people have the
information they need
Expected Outcomes
• Streamlining and prioritization of
uncertainty assessment
• Greater transparency and awareness
• Educational for scientists (and beginning
scholars, students of applied science)
• Educational for decision-makers
• Boundary object

Relevance
Legitimacy
Using DUST to Move Forward…
• DUST: educational, screening tool, a
heuristic
• Informs the interpretation of, and learning
from, past projects
• Informs the development of future
research projects
Future Directions
• NCAR-RISA Collaboration
– Workshop to establish linkages in FY05
• Communication of Uncertainty to DecisionMakers
– Collaboration with DMUU at RAND Corp.
• Feasibility Limits of Adaptation Strategies
to Sea-Level rise
– Project development during early FY05
– Comparative case study approach
– Multi-disciplinary collaboration
• Decision-making at the Climate–Health
Interface
– Heat waves
– Air quality management
• Scales of decision-making
- Carbon flux
- Water resource management
• Societal use of weather information
