# Will geothermal cooling be greatly affected by global warming?

Geothermal cooling has been an attractive option in the U.S. Northeast since it emits very little carbon into the atmosphere compared with compressed refrigerant systems which use lots of electricity. Geothermal cooling is based on the fact that the ground basically stays around 50-55 degrees farenheit all year round unless the ground is near a hot spring or volcanic fault line. I would think that the temperature of the earth will warm a little bit which would affect the temperature of the cooling fluid.

• Do you perhaps mean a GROUND SOURCE heat pump? These are often fraudulently called "geothermal" by salespeople, but a true geothermal system is something quite different. Ground source heat pumps increase the efficiency of heating & cooling by using the constant temperature underground as one side of a heat pump, rather than the air. – jamesqf Oct 7 '19 at 3:54
