5 Lurie Garden Changes in precipitation patterns (wetter winters and springs; drier summers) Increases in extreme storm events (e.g., rain, snow, wind) Increases in the number of extreme heat days in summer (In a high-emissions scenario, 32 days > 90° by mid-century) Winters becoming “less cold” (average nighttime lows increasing; less ice cover = increased beach erosion) Source: Hayhoe et al. Journal of Great Lakes Research, 2010. What Can We Expect?

6 Lake Michigan 1973-2010 Water warmed by 3.3°F Winter air temperatures over lake warmed by 2.7°F Ice cover reduced by 77% Jan 2012, National Weather Service Wang et al 2012

7 1990 map Based on 1974- 1986 2012 map Based on 1975- 2005  Within next several decades: 5b – 6a*  By end of century: 6b (L) – 7a (H) *Irrespective of future emissions scenarios (Hellmann et al. 2010) The 2012 map is generally ½ zone warmer than previous map throughout much of the US

8 Flooding Impacts- Midwest

9 Climate Impacts: Biodiversity  Direct effects  Temperature  Precipitation  Increased intensity of weather events  Indirect effects  Range shifts  Predators/disease/invasives  Timing of important annual cycle events ( Lymantria dispar ) ( Baptisia leucantha )

10 Climate Impacts: People  Direct effects  Temperature: heat-related diseases  Indirect effects  Increased intensity of weather events:  Flooding affecting residences, public transportation, bridges  Electricity shortages and changes in energy demands  Municipal costs such as landscaping, road maintenance, emergency response

15 More extreme rain events increased inputs of nutrients, pollutants, and sediments increased freq of channel-forming events scouring of aquatic habitats Increased flashiness surface water flow flooding headward erosion run off

16 Near-term * Mid-term * Long-term Adaptation Actions ImpactsStressorsGoal Stormwater Water Quality Habitat Monitoring Stormwater Water Quality Habitat Management Contractors Residential Municipalities Outreach

17 City Hall rooftop Lurie Garden Humboldt Park Northerly Island

18 Urban Climate Action  Convened based on need expressed by resource managers  27 people, 15 organizations, 9 City Departments (AKA “Climate Fellows”)  3 Climate Clinics

19 Urban Climate Action Identifying climate-sensitive decisions What planning and management actions could reduce a site’s vulnerability to specific climate-related impacts?  Drought and heat stress  Extreme storms (e.g., precipitation flashiness and flooding)  Loss of key functional system or species
