Climate breakdown can be seen in the data, the scientists say. “When we compare the total terrestrial water storage data with climate datasets, the trends broadly correlate,” said Mohammad Shamsudduha, professor of water crisis and risk reduction at UCL. It is a critical resource: across member states, groundwater accounted for 62% of the total public water supply and 33% of agricultural water demands during 2022. A spokesperson for the European Commission said its water resilience strategy “aims to help member states adapt their water resource management to climate change and to address man-made pressures”. In Iran, Tehran is closing in on “day zero” when no tap water is available, and water rationing is being planned.
