‘Global warming is reflected directly in the groundwater, albeit damped and with a certain time lag,’ said Peter Bayer, senior assistant at ETH Zurich’s Geological Institute in Switzerland.
The data reveals that the groundwater close to the surface, down to a depth of around 60 metres has warmed up significantly in the course of global warming over the last 40 years.
This water heating follows the warming pattern of the local and regional climate which, in turn, mirrors the pattern of global warming. The groundwater reveals how the atmosphere has made several temperature leaps at irregular intervals.
‘We were quite surprised at how quickly the groundwater responded to climate change,’ Peter Bayer added.
