CNN —A phenomenon that scientists have called “underground climate change” is deforming the ground beneath cities, a study conducted in Chicago has found. Technically known as “subsurface heat islands,” underground climate change is the warming of the ground under our feet, caused by heat released by buildings and subterranean transportation such as subway systems. “Deformations caused by underground climate change are relatively small in magnitude, but they continuously develop,” he said. “Calling it climate change seems like a bit of a coattail thing,” Archer, who was not involved with the study, said. The term “underground climate change,” however, was not coined for this study — it has been in use, and the phenomenon a subject of research, for some time.
