Before revision: Scientific Evaluation and Discussion The assumption of a megadrought in the year 1540 is primarily supported by more than 300 contemporary chronicles from across Europe, which consistently describe the effects of prolonged drought and heat, such as a significant precipitation deficit, extremely low levels of major rivers, widespread wildfires, the lowering of groundwater levels (resulting in the drying up of wells), as well as severe consequences for agriculture and livestock farming.
