The Hidden Threat: Trapped Heat Endangers Buildings Underground
Heat trapped under the surface, known as "underground climate change," is causing cities like Chicago, New York, and London to sink and threatening buildings and infrastructure. This phenomenon is different from atmospheric climate change caused by greenhouse gases and is a result of heat emitted by subways and buildings directly into the ground. The spreading heat causes the ground to deform, leading to cracks in city structures. The Biden administration is focusing on addressing this issue and promoting resilience in underground infrastructure. Mitigation measures such as thermal insulation and capturing excess heat for geothermal energy can help combat this problem.
