The Subterranean Threat: Climate Change's Silent Impact on Urban Stability

A new study from Northwestern University reveals that the ground beneath downtown Chicago has warmed by an average of 5.6 degrees Fahrenheit since the mid-20th century, primarily due to heat leaking from basements and other underground structures. This increase in temperature has caused the layers of sand, clay, and rock beneath buildings to subside or swell, leading to cracks and defects in walls and foundations. The phenomenon, known as "underground climate change," is not unique to Chicago and is occurring in cities worldwide. The study suggests that improving insulation and utilizing heat-absorbing technologies can help mitigate the issue.
