Conservation of Urban Biodiversity Under Climate Change: Climate-Informed Management for Chicago Green Spaces

• 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?
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%

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

Climate Impacts: People
Direct effectsTemperature: heat-related diseases
Indirect effectsIncreased 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

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

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
