Fig. 1: Processes and impacts related to groundwater temperature changes.

a–e, Increases in surface air and ground surface temperatures (a) drive increases in groundwater temperatures (b) that, in turn, impact the geothermal potential for shallow geothermal energy systems (c), groundwater chemistry and microbiology, which in turn impacts water quality (d) and groundwater-dependent ecosystems (e).
