摘要：

Europe has been experiencing a severe drought for years. Across the continent, groundwater levels have been consistently low since 2018, even if extreme weather events with flooding temporarily give a different picture. The beginning of this tense situation is documented in a publication by Eva Boergens in Geophysical Research Letters from the year 2020. In it, she noted that there was a striking water shortage in Central Europe during the summer months of 2018 and 2019. Since then, there has been no significant rise in groundwater levels; the levels have remained constantly low. This is shown by data analyses by Torsten Mayer-Gürr and Andreas Kvas from the Institute of Geodesy at Graz University of Technology (TU Graz). As part of the EU's Global Gravity-based Groundwater Product (G3P) project, they used satellite gravimetry to observe the world's groundwater resources and documented their changes in recent years.
