7. 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 more Clarence River by Scott Lenton

25. 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…

26. Likely impacts? • What would you expect from higher temperatures and reduced annual average rainfall…?

27. 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) Fire fighting in the Mount Burrell Forest in Northern NSW by Mike Rushby.

28. 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 Erosion of Access Road at Minnie Bay by Phil Rogers, Envite

29. 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 Sheep at Cabonne, courtesy WBC Strategic Alliance

30. Implications Assets and infrastructure - Damage to and maintenance of: • Buildings (cooling costs) • Coastal infrastructure • Open space, recreational facilities • Stormwater drainage / levees • Wastewater • Water supply Sewer surcharge during Hunter storms 2008 by Hunter Councils Inc.

31. Implications NRM and biodiversity • Loss of biodiversity • Coastal management • Weeds and pests Community • Increased demand for health care & emergency services Land use planning • Loss of property and assets • ESD design into developments Windmill by @dino 2006www.flickr.com

32. Implications Economic impacts • Impact on tourism • Insurance and liability issues • Electricity supply Waste • Large emission source that council can influence • National Greenhouse & Energy Reporting System (NGERS) • CPRS Upper Colo River, NSW by island homewww.flickr.com

33. Climate change is everybody’s business • Community Health & Social Planning • Planning, Assets & Infrastructure • Open Space & Biodiversity • Rangers & Traffic Services • Mangers & Directors • Legal Advice • Finance Photo provided by Scott Lenton

34. 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

35. Why? • Why should Council take action on climate change?

36. Why act? Avoid: • Disruption to council services • Unbudgeted financial impacts • Litigation Fulfill: • 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

37. LGSA support • Needs Analysis Survey • Climate Change Summit • Regional Workshops • Workshop Package

38. Any questions?

39. 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

40. Conclusion • Thank you • Evaluation forms
