Climate change beneath our feet: Exploring the thermal evolution of shallow groundwater
Shallow aquifers are sluggish systems in comparison to the connected atmospheric environment. They act like batteries that memorize thermal variations induced from above. We observe delayed thermal responses to global climate change in measured long-term time series of groundwater temperatures. Strongest thermal anomalies are found beneath cities, where the combined effect of multiple factors induces evolving subsurface urban heat islands. This presentation reveals spatial and temporal trends observed in rural and urban environments in central Europe. Utilizing measurements from groundwater, land-surface and air temperature, thermal coupling is studied through correlation analysis and analytical simulation.
