Trends and Projections

WICCI climate scientists have “down-scaled” global climate models to project how Wisconsin’s climate has been changing and how it might change in the years to come. View the maps to see historical trends and future projections for temperatures and precipitation.

The studies of historical trends and future projections reveal an emerging consensus on the range of possible climate changes that Wisconsin will experience. In particular, these studies find that Wisconsin is likely to become a much warmer state over the next few decades, with average temperatures more like those currently experiences in states hundreds of miles to our south.

Our state is also likely to become somewhat wetter, with a modest increase in total precipitation and in the number of intense rainfall events. The amount of climate change varies by season, with winter experiencing the greatest warming and most likely increase in precipitation.
