This document discusses five obstacles to effective climate change decision making: 1) data used is often not meaningful or helpful, 2) stakeholder objectives and concerns are not sufficiently addressed, 3) attributes and measures used to characterize impacts are inadequate, 4) research is loosely tied to decisions that need to be made, and 5) there is little learning from past successes and mistakes. The document examines these obstacles in more detail and provides examples to illustrate challenges with using complex data, addressing stakeholder objectives, developing appropriate attributes and measures, and incorporating learning over time into the decision process.

Five Obstacles to Effective
Climate Decisions:
A Decision Science Perspective

3. Introduction
• The following
discussion stems
from decision aiding
work carried out in
two contexts;
adaptation to
climate change in:
– Coastal British
Columbia
– Nunavut Territory
4. Introduction
• Though quite different
in terms of the levels of
development and
infrastructure, both
study sites shared a
common complaint:
– Despite years of
research (and millions of
dollars spent) people
were seeing very little in
the way of adaptation
action.
– “You can’t study our
problems away…”
5. Introduction
• Five common concerns:
1. The data used to describe the problems associated with
climate change are frequently not meaningful or helpful.
2. The objectives and concerns of affected stakeholders
are not receiving sufficient attention.
3. The attributes and measures used to characterize
climate change impacts, and the anticipated
consequences of alternative management plans, are
often inadequate.
4. Ongoing research is often only loosely tied to the
decisions that need to be made.
5. There seems to be very little learning from past success
stories as well as mistakes.
8. Dual Processing
• SYSTEM 1 is fast,
intuitive, highly
inductive, and based
heavily on our
instinctive emotional
(affective) responses to
stimuli.
• SYSTEM 2, is slower,
based on rules of logic
and rationality, highly
deductive, and based
heavily on effortful
calculation.
9. Numeracy Issues

12. Psychophysical Numbing
“I am deeply moved if I see one man
suffering and would risk my life for him.
Then I talk impersonally about the possible
pulverization of our big cities, with a
hundred million dead. I am unable multiply
Value of Life Saving
one man’s suffering by a hundred million.”

14. Objectives
• The objectives of stakeholders and decision
makers are the basis for considering any
decision.
• Therefore, the first step in any decision process
is for those involved to carefully consider their
objectives by clearly defining what it is they want
to achieve in a given decision context.
• This objectivesfocus is in contrast to an
alternativesfocus, which involves analyzing the
available alternatives and selecting the ‘best’ one
from a set of implied, and often poorly defined,
criteria.
15. Objectives
• Despite their importance during decision making,
a thoughtful and thorough exploration of
objectives that will guide a decision is only
seldom undertaken.
• Decision makers and stakeholders seldom
differentiate between means and ends
objectives.
– This is important because decisions about climate
change are also linked to other areas of concern.

17. Attributes & Measures
• World Summit on Sustainable Development,
Johannesburg 2002
• Indicators in Integrated Coastal Management,
Ottawa 2002
• Much of the focus has been on the
identification of natural processes that require
further scientific study and/or should be
closely monitored in response to climate
drivers.
• Inventories with an emphasis on establishing
changes relative to some baseline.
18. Attributes & Measures
• Inventory data frequently does not provide
the kinds of insights that decision makers
desire (but they end up “using” it anyway):
– …because they often remove focus from what
matters to stakeholders and decision makers (i.e.,
their objectives).
– …because they are not presented at the
appropriate temporal or geographic scale.
– …because they fail to expose key tradeoffs that
will need to be addressed.

24. Research & Monitoring Needs
• AnalyticDeliberative Process.
– Several successive rounds of deliberation by
stakeholders and analysis by technical experts
as part of a deliberate march towards a risk
management decision.
• Each successive round of analysis and
deliberation is meant to yield an improved
understanding on the part of both the
stakeholders and experts regarding the
various attributes that are “at risk” in an
ecological system.
• The analyticdeliberative process is not
simply a means for synthesizing the
information obtained through a set of
unrelated and predominantly expertdriven
risk assessments; it is an important shaper of
a longrange risk assessment and decision
making process.
25. Learning Over Time
• Climate decisions are questions
masquerading as answers.
• If we view decisions as
questions, then the outcomes of
these decisions become
treatments, in an experimental
sense.
• Adaptive management has two
key parts:
1. Implementing varied climate
“treatments” (e.g., across space and
time).
2. Monitoring, learning, and adjusting.
26. Learning Over Time
RESILIENCE
• Many would argue that,
globally speaking, we’ve
already done serious
damage to the climate.
• Decisions aimed at
reducing and responding
to the effects of climate
change should help (vs.
hurt).
27. Learning Over Time
SCALE
• There is often a need to
focus narrowly, in terms
of time and space, during
decision making.
• Spatially varied climate
management
“treatments” are already
in place.
– e.g., forestry projects in
India; energy projects in
Europe, fuel taxes in
Canada, Daylight Saving
Time in Australia (2000).
28. Learning Over Time
ETHICAL CONCERNS
• Sadly, the global
economy in concert with
regional variability in
climate already
inequitably distributes
costs and vulnerability
across communities and
places.
29. Learning Over Time
COMPLEXITY
• Overall, the basic
framework for carrying
out adaptive climate
management is already
in place.
• What’s missing is a
system for monitoring
and learning.
