Terminology
• Climate: Average weather conditions over a long period (30 years)
• Climate change: Long term shift in average weather conditions
• Extreme events:
Severe storms (rain,
hail, wind) cyclones,
fire and moreClarence River by Scott Lenton

Historical evidence
Rate of temperature change (°C/10 years) over the last 39 years
Historical evidence
Rate of rainfall change (mm/10 years) over the last 39 years

Projections
• In the next Module we will examine the projections for NSW in more detail & also the projections for this region
• In this Module we will briefly look at some potential impacts and implications…
• What would you expect from higher temperatures and reduced annual average rainfall…?
Likely impacts?
Likely impacts
• Changed distributions of pests, weeds and disease (i.e. loss and gain) & extend drought
• Heat waves - risk for vulnerable communities (elderly, frail and infants)
• Increased frequency & intensity of bushfires and extended fire season (temperature, evaporation)

Likely impacts
• Lower rainfall less water availability, reliability• Increased storm intensity increased flooding• Increased storm surge and sea level rise
erosion, inundation of
coastal lowlands &
modification of estuaries

Risks to communities
• Endangering life – e.g. bushfire, storms• Heatwaves – e.g. dehydration at sporting and
outdoor events• Disruptions to supply chains• Primary industries• Property – e.g. flooding,
storm damage, erosion

Implications
Assets and infrastructure - Damage to and maintenance of:
• Buildings (cooling costs)• Coastal infrastructure• Open space, recreational facilities• Stormwater drainage / levees• Wastewater• Water supply

Implications
NRM and biodiversity• Loss of biodiversity• Coastal management• Weeds and pestsCommunity• Increased demand for health care & emergency services Land use planning• Loss of property and assets• ESD design into developments

Implications
Economic impacts• Impact on tourism• Insurance and liability issues• Electricity supplyWaste• Large emission source that council can influence• National Greenhouse & Energy Reporting
System (NGERS)• CPRS

Council’s response
• Council has a dual role– Mitigate, or reduce, greenhouse gas
emissions to reduce climate change– Adapt, or prepare for, unavoidable climate
change e.g. council operations, staff, infrastructure
By armisteadbooker
Why?
• Why should Council take action on climate change?
Why act?
Avoid:• Disruption to council services• Unbudgeted financial impacts• LitigationFulfill:• Duty of care to the community• Meet KPIs in strategic plans• Liveability and economic viability of a region• Need to incorporate ESD into activities & decision
making - requirement of the Local Government Act 1993
LGSA support
• Needs Analysis Survey • Climate Change Summit • Regional Workshops • Workshop Package
Any questions?
Achievements from the workshop
During the workshop we have explored:• Historical evidence for climate change• The Greenhouse Effect• Projections for NSW• Likely impacts• Implications for council • Council’s role
