"There's already a significant amount of heat beneath our feet," Rotta Loria said.
The research, published in July in the journal Nature, detailed how heat trapped under the surface is causing a phenomenon called "underground climate change" and could cause major cities including Chicago, New York and London to "sink."
This underground climate change is different from the climate change in the atmosphere, which comes from greenhouse gasses caused by burning fossil fuels.
As the heat spreads, the ground also deforms, which can cause city structures and infrastructure to crack.
While researchers have worried about the potential of cities to sink due to heavy building loads, spreading heat like this can cause similar displacements.
