State of the WA Environment Climate Change
Vulnerabilities ImpactsThe unavoidable need
for managing change
  • Dr Wally Cox
  • Chairman
  • Environmental Protection Authority

SoE Overview
WA State of the Environment 2006
  • Report to community and decision makers (every 5
    years)
  • Major environmental issues and trends
  • Raise awareness
  • ID responses required
  • Report out in late 2006

WA State of the Environment 2006
Aspects of climate change
5
WAs position
WA State of the Environment 2006
  • Primary focus greenhouse gas emissions mitigation
  • Global emissions reduction beyond our control
  • Change is inevitable
  • WA must prepare to live with and adapt to climate
    change

6
Vulnerabilities
WA State of the Environment 2006
  • Key drivers temperature and rainfall
  • Every living organism has a T R range
  • Implications for natural and economic systems in
    WA

7
Key vulnerabilities - natural systems
8
Key vulnerabilities - economic systems

Consequences
Yanchep Caves Stygofauna and root matt communities
Banksia prionotes
Banksia littoralis
Regelia ciliata

  • Median monthly flows for the Harris River, near
    Collie before and after 1976

12
Adaptation - Principles
WA State of the Environment 2006
  • Prevent and/or modify threats
  • Change uses / activities
  • Change location of activities
  • Expand research into impacts, technologies and
    methods of adaptation
  • Educate, inform and encourage behavioural change

13
Adaptation - capacity
WA State of the Environment 2006
  • Some areas will be able to adapt
  • Water sector
  • Coastal planning
  • Agriculture
  • Some wont
  • Vulnerable SW ecosystems
  • Wheatbelt spp.
  • Southern rangelands?
  • Coral reefs Ningaloo, Dampier Archipelago

14
Intervention?
WA State of the Environment 2006
  • Extreme / deliberate intervention -
  • Last line of defence
  • Millenium Seed Bank Project, cryogenic chamber
  • Yanchep stygofauna

Cost of intervention Technology
requirements Timeframe Knowledge
Intervention adaptive management
Natural adaptation

Conclusion
WA State of the Environment 2006
  • The Greenhouse Bulldozer is coming
  • We have a moral obligation to reduce our GHG
    emissions
  • We need to
  • Enhance our understanding of the impacts for WA
    environment and sectors
  • Plan to adapt AND
  • Adapt
