2. Intergovernmental Panel on Climate Change

3. Climate Change Worldwide IPCC 2007

4. The story so far:

6. Carbon Dioxide is the most important greenhouse gas from a 280 parts per million before the industrial revolution to 379 ppm in 2005 the range over last 650,000 years has been 180 to 300 ppm growth rate (1995–2005) averaged 1.9 ppm per year

7. Climate Change in Australia IPCC 2007

8. Major Findings Regional climate change has occurred since 1950 There has been 0.4 to 0.7°C of warming There has been an increase in the intensity of Australian droughts Sea level has risen by about 70 mm

9. Less rain less rain in southern and eastern Australia more heatwaves, fewer frosts, more rain in north-west Australia

10. Water supplies

11. Graph copyright Melbourne Water 615 GL – 385 GL = 130 GL or 34% decrease (Into Thomson, Upper Yarra, O’Shannassy and Maroondah dams)

12. Future predictions

13. Rising sea levels

14. Significant loss of biodiversity is projected to occur by 2020 in some ecologically rich sites

15. IPCC 2007 diagram of key issues

16. Risks to Buildings, Roads, etc. Increased storm damage Increased damage by bush fires Extreme weather events will cause more damage to things like roads More blackouts

17. Risks to Agriculture & Forestry Production from agriculture and forestry is projected to decline by 2030 over much of southern and eastern Australia due to increased drought and fire.

18. Risks to Health Increased heat related deaths Warmer temperatures increase food and water-borne diseases Mental health (drought causing stress) Increased fire smoke affecting asthma suffers

19. More Risks to Health It is predicted that there will be changes to mosquito-borne diseases like Dengue Fever & Malaria in northern Australia. The impacts of smog on health are still uncertain.
