Introduction
Illinois is known for its hot and humid summers, its gentle landscape, and its rich soils, all of which contribute to enormous agricultural productivity. The state is home to 12.6 million people and one of the country’s largest and most vibrant cities, Chicago. Numerous rivers, streams, wetlands, and lakes dot the landscape of Illinois, drawing anglers, boaters, birders, bathers, and crowds of visitors each year.

Many of the activities Illinoisans engage in—such as agriculture, urban living, outdoor recreation, and others—are at risk from climate change. This change is largely driven by human activities, primarily the burning of fossil fuels to produce electricity and drive our cars, which in turn emits gases—principally carbon dioxide—that blanket the planet and trap heat. The resulting fundamental change in the Earth's atmosphere and climate is affecting people and the environment in the Great Lakes region.

In the Illinois section of this web feature, we explore what a changing climate could mean for the state. Specifically, we examine how climate is projected to change in Illinois; how these changes may impact human health, agriculture, water supplies, property and infrastructure, aquatic ecosystems, and tourism and recreation; and how Illinoisans can help reduce these potential impacts by pursuing several solutions strategies.

After you’ve learned about the threats that a changing climate pose to Illinois, please take a couple of minutes to tell policymakers to begin tackling the problem. This is easy to do on our action pages.
