Wisconsin’s climate has always been changing—most notably as the last Ice Age ended, glaciers melted, and the plants and animals present today slowly made their way north. It will continue to change into the future, but now due in large part to human activity, and at a rate much faster than at any other point in history. To make predictions about the rate and magnitude of future climate changes in Wisconsin, climatologists at the University of Wisconsin-Madison analyzed past climate data and modeled future projections for Wisconsin.
