Extreme Weather Wisconsin has experienced an increase in both annual precipitation and heavy rain events, trends which are projected to continue. Projected increases in winter and spring precipitation will pose a continuing risk of spring planting delays, as well as an increased risk of flooding. Snowfall is projected to decline due to warmer temperatures.

Severe drought, a natural part of the Wisconsin climate, is a risk to this agriculture-dependent state. Increased rate of soil moisture depletion during dry spells due to higher temperatures, along with earlier snowmelt and a greater frequency of dry days, may increase the intensity of future naturally-occurring droughts.


Extreme Weather


Climate Change Average annual temperature has warmed about 2°F since the beginning of the 20th century. Under a higher emissions pathway, historically unprecedented warming is projected by the end of the 21st century. Extreme heat is of particular concern for densely populated urban areas like Milwaukee, where high temperatures and high humidity can cause dangerous conditions.

CASE STUDY: Metro Health Hospital



• The oldest health system in Cleveland, and one of the largest and most comprehensive health systems in Northeast Ohio

• MetroHealth is a center for research and education, an important community anchor, and a provider of world-class care.

• Serves approximately 1.4M patients per year.

• Currently undergoing $950M campus transformation.

• Transformation project includes a new 650,000 SF, 300-bed main hospital to replace two existing towers, a new central utility plant, and loading dock and logistics building

• Target State: 21st Century Process Neutral medical building.

Option Pro Con

2.1 Code Minimum Meets Code – (Worst Building you can legally build)

Building cannot continue to be occupied for extended duration.

2.2 Standard of Care Meets Code and allows for minimal function of facility.

Building function and protocol would need to be revised during an outage.

2.3 Best Practices Addresses patient care needs and select building functions.

Could occupy facility but some systems would not function.

2.4 Island Power All building loads would function*.
