On the banks of the Fox River in the southwestern
corner of Lake County, Illinois, you can almost see back through time. Not so long ago, at least on the 4.5-billion-year arc of Earth’s history, a wall of ice between 700–2,000 feet tall covered everything in view today.
Today, 691 acres near the Fox River’s eastern shore make up Grassy Lake Forest Preserve in the town of Lake Barrington.
Subtle glimpses of the area’s glacial history are visible in the landscape there and elsewhere in the county. They’re remnants from the most recent Ice Age, which ended 10,000–12,000 years ago.
Average temperatures were only 7–13 degrees
colder then compared to today. Already, Illinois’ average daily temperature has risen 1–2 degrees Fahrenheit over the past 120 years. Depending on current and future levels of heat-trapping greenhouse gas emissions, “by the end of the 21st
century, unprecedented warming of 4–9 degrees or 8–14 degrees is likely in Illinois.”
We’re on the precipice of another major shift in
climate, both globally and locally in Lake County.
