3. Climate change: the great contemporary dilemma
RMIT University©2010 CCAP, Global Cities Institute
5. Clarifying climate change agendas
Climate science / impacts
Global warming / mitigation
Climate change / adaptation / disaster risk reduction
Mitigation: ‘avoiding the unmanageable’
Adaptation: ‘managing the unavoidable’

6. What should we be adapting to?
Low emissions scenario High emissions scenario
2070 2070
Temperature + 0.9 ºC to + 2.0 ºC + 1.8 ºC to + 3.8 ºC
Number of days over 14 20
35 ºC: Melbourne
(current 9)
Number of days over 45 59
35 ºC: Mildura
(current 32)
Rainfall + 2% to - 14% + 3% to - 25%
Drought Likely increase between 10% and 80%
Extreme events
Sea level rise Likely rise between 0.18m to 0.59m by 2095, with a
possible much greater rise
Extremes Likely to be more extreme rain events, and more extreme
bushfire events

7. Research activity: RMIT
• Impact of the 2009 heatwave on critical urban infrastructure
• Framing climate change adaptation – guidance for local
authorities / capacity building (navigator, economics, social
narratives)
• Emergency management (bushfires) and use of IT simulation
to improve decision-making
• Climate resilient seaports
• Climate change and sustainable urban development in the
Asia-Pacific region

9. ‘Think tank’ activity: VCCCAR
• Adapting aspirations and
expectations on the coastal
suburban and regional fringe
• Gippsland climate change and
adaptation study
• Regional Business Development in a
Variable and Changing Climate:
Strategies for Central Victoria

10. Challenges
• Means and variability in
climate will be different in the
future, and spatially /
regionally differentiated
• How to cope, and make
decisions, under conditions of
uncertainty
• Future climate change is only
one source of uncertainty
• Multiple hazards and joint
probability events
• Cascading effects
Flooding in Victoria 2011: Herald Sun
• Importance of socio-economic
drivers (climate adaptation /
climate sensitive / non climate)

11. Opportunities
• Tools for helping to cope with
uncertainty: use of scenarios,
risk assessment, flexible
management approaches
• Australia long experience of
dealing with variable climate
• A chance to capitalise on past
success and encourage
further innovation
• Emerging markets: new
technologies and behaviour
change (water tanks etc)
• Adaptation as an iterative
learning process, which
requires new relationships and
ways of working
