Climate change could increasingly impact Milwaukee County residents and county operations by the end of the century, a
new report commissioned by the County. The ‘climate vulnerability’ report identifies three primary climate hazards in Milwaukee County: heat waves, flooding, and poor air quality. Under a global high-emissions scenario, average temperatures in the County could match those of St. Louis, Missouri by the year 2100, with wetter winters and drier summers.
As described in the report, climate change will have direct impacts on Milwaukee County residents and businesses. For example, heat waves could increase demand for air conditioning, leading to power outages and increased heat-related health concerns for residents. Unfortunately, these negative impacts could be compounded by the fact that vulnerable communities do not have the same access to adequate healthcare, transportation, or cooling centers.
Consultants Energetics found that some communities in Milwaukee County may be less resilient to climate change. For instance, neighborhoods with high concentrations of impermeable surfaces (buildings, paved roads, and parking lots), and a deficit of tree canopy and open space are more susceptible to heat waves and poor air quality. In general, local communities with less resilient infrastructure also tend to have higher social vulnerability.
The report identifies several park properties located in Milwaukee County that could potentially be affected by 100-year and 500-year floodplains (Hart Park, Kletszch Park, Lincoln Park, and Brown Deer Village Park). Flooding of these or other park properties could make them less accessible and enjoyable for area residents and visitors. This could result in decreased physical activity and social isolation, which can have negative impacts on health and well-being.
Findings from the report will inform Milwaukee County’s
Climate Action 2050 Plan. The plan will serve as a roadmap for Milwaukee County to:
