Temperature Goes Up Underground
①As climate change brings dangers to people, we are now facing another problem—underground climate change.
②With the development of cities, the rising underground temperature is causing the ground to heat up and deform(变形), reported by a study team from Northwestern University. In the last three years, the team had put more than 150 temperature sensors(感应器)under Chicago. The temperatures they recorded were surprising. For example, the team created computer models to see how temperatures will influence the ground until 2051.
③The models showed, when heated, the ground may go up by as much as 1.2 centimeters, or go down by as much as 0.8 centimeters. This may even cause the ground to break up, leaving people who live and work above in dangerous situations.
④However, Rotta Loria, who led the study, said in a report, “It takes a long time to see the bad effects.” As scientists have already known a lot about underground climate change, future plans for cities should be considered. Materials that take in heat can be used to keep the heat from entering the ground.
⑤The team also pointed out that the rising temperature could be seen as an opportunity. City planners can try to collect heat underground and send it above for heating.
