7. Climate model A climate model is a numerical representation of the climate system and combines known laws of physics with factors such as climatic parameters and atmospheric factors to compute the evolving state of the climate in response to the changing composition of the atmosphere (Ebi 2004) A climate model is a numerical representation of the climate system and combines known laws of physics with factors such as climatic parameters and atmospheric factors to compute the evolving state of the climate in response to the changing composition of the atmosphere (Ebi 2004)

10. Impacts of climate change on health in Ireland Temperature related mortality Temperature related mortality Food-borne disease Food-borne disease Water-borne disease Water-borne disease Vector-borne diseases Vector-borne diseases Other indirect effects, e.g. allergies, skin cancer Other indirect effects, e.g. allergies, skin cancer

12. Reductions in mortality, particularly from cardiovascular and respiratory mortality, and principally in the over 75 age group Reductions in mortality, particularly from cardiovascular and respiratory mortality, and principally in the over 75 age group

13. Future changes in temperature related mortality 2010 - 392040 - 692070 - 99 % Change in mortality (-0.4 - 2.3) -2.1 (-1.2 - 3.5) -4.3 (-2.1 - 6.9)

15. Foodborne disease

18. For every 1 degree rise in mean temperature: Salmonella 8% rise Salmonella 8% rise Campylobacter 6% rise Campylobacter 6% rise VTEC 6% rise VTEC 6% rise

19. Water-borne disease “ ”Water quality is only of importance to you if you use a tap or a toilet” Boyden, 2006

20. Climate change and rainfall in Ireland Wide-spread reduction in rain in East and South- East Wide-spread reduction in rain in East and South- East Increase in winter rain in the West Increase in winter rain in the West Seasonal flooding may occur over a larger area and persist for longer periods of time. Seasonal flooding may occur over a larger area and persist for longer periods of time.

21. Water quality and health : a multi-factorial issue Warmer temperatures - growth of micro-organisms Increased run-off and flooding VTEC and cryptosporidiosis Water treatment plants need urgent attention

22. Flooding No warning Night time Cold Immediate Immediate Mortality, trauma, pollution Mortality, trauma, pollution Delayed Delayed Leptospirosis,earache, skin infections, Leptospirosis,earache, skin infections, dampness, asthma dampness, asthma Psychological Psychological

23. Reduced water supplies Increased demand for water Population increases in the East Population increases in the East Warmer temperatures Warmer temperatures Increased use of surface water Decreased efficiency of treatment plants

24. EU Water Framework Directive To achieve ‘good status’ for all water bodies by 2015 To achieve ‘good status’ for all water bodies by 2015 New Drinking Water Regulations – will result in improved drinking water quality New Drinking Water Regulations – will result in improved drinking water quality

25. ‘Safe water cannot be taken for granted’. (Wall 2001)

26. Other indirect effects Malaria and Lyme disease Skin cancer Allergies

27. Summary of findings Less temperature related mortality Less temperature related mortality Increase in food-borne disease Increase in food-borne disease Increase in water-borne disease Increase in water-borne disease Change in vector-borne diseases Change in vector-borne diseases Increase in skin cancer Increase in skin cancer Change in timing and location of allergic diseases Change in timing and location of allergic diseases
