13 Increased water demand Warmer temperatures, more periods of extreme heat Increase water demand (households, businesses, municipalities) (trending) Demands on services Increased costs (abstraction, water treatment, supply)

14 Decline in winter recreation opportunities Less precipitation falling as snow; warmer winter temperatures; reduced winter snowpack Decline in winter recreation opportunities (trending) Stress and anxiety, decline in quality of life Public health loss of exercise opportunities Decline in economic output, selected businesses Job losses, selected sectors Potential reduction in property values (out migration) Impact on reputation loss of tourism visits

15 Heavy snowfall / blizzard Increased in extreme precipitation events in winter Heavy snowfall / blizzard (recurring) Public health (snow loading and accidents) Disruption to economic activities / transport disruption Environment Stress on wildlife Interruption to lifelines (power, water) Costs to town (clearing, clean up) Property damage (snow loading and collapse) Demand on emergency services

16 Freeze-thaw cycles Increased variability of temperatures Freeze thaw cycles (recurring) Public health (injuries) Reduced recreational opportunities Disruption to economic activities (transportation disruption) Increased road maintenance costs (sanding)

17 Human contact with wildlife Shifting ecosystems, upland, reduced alpine tundra Human contact with wildlife (recurring) Public health (potential for fatalities, injuries) Viewing opportunities Environment Destroy and remove wildlife from town Economy Impact on reputation loss of tourism visits Costs to town

18 Increase in vector-borne diseases Less periods of extreme cold spells, warmer temperatures Increase in vector-borne diseases (trending) Public health, illnesses and diseases Loss of economic activity, tourists staying away Forgone productivity Environment Loss, stress, wildlife

19 Infestation of pests / invasive species Less periods of extreme cold spells, warmer temperatures Infestation of pests / invasive species (recurring) Visual quality impact on forests Injuries or fatalities from new dangerous animals (e.g. killer bees) Loss of tourism Impact on forestry sector Crop destruction Environment Forest loss, habitat loss Native species displacement

20 Freezing rain / ice storm Warmer winter temperatures and increased proportion of winter precipitation falling as rain Freezing rain / ice storm (recurring) Injuries (slips and falls) Dangerous roads (accidents and fatalities) Disruption to economic activities / transport disruption Repair and restoration costs Stress on emergency service personnel Interruption to lifelines (power, water) Property damage (ice loading and collapse)
