Based on downscaled models for this region, which is a strategy that connects global scale predictions and regional dynamics to generate regionally specific forecasts, the following impacts are expected to occur: (Reference 18)
- “Migrating seasons” for regional climates: By century’s end, winter is forecasted to feel similar to (edit) and summers similar to (Edit) or, under high emissions, (Edit).
- Temperature increase: Under high emissions, the Midwest may experience 45-85 days over 95° F by century’s end.
- Heat-related morbidity: By 2085, there may be (Edit) heat-related Minneapolis Saint Paul metro-area deaths per year.
- Changed precipitation patterns: As compared to the 1961-1990 average, spring and winter in 2070 could have 20-35% more.
- Plant Hardiness Zone shift: The Midwest’s zones have shifted and could continue to shift ½ to 1 zone every 30 years..
- Great Lake impacts: Modeling future lake level projections is extremely complex. The most recent research shows a range of possible conditions, ranging from a slight decrease to a slight increase in Lake Superior during this century (Reference 19). Additionally, the Great Lakes could experience an increased likelihood of extreme storms.
