Compared to the risks associated with climate warming and extremes, the risks of climate-induced drying to animal species remain understudied. This is particularly true for water-sensitive groups, such as anurans, whose long-term survival must be considered in the context of both environmental changes and species sensitivity. Here, we mapped global areas where anurans will face increasing water limitations, analysed ecotype sensitivity to water loss, and modelled behavioural activity impacts under future climate change scenarios. Predictions indicate 6.6% to 33.6% of anuran habitats will become arid-like by 2080–2100, with 15.4% to 36.1% exposed to worsening drought, under an intermediate to high emission scenario, respectively. Arid conditions are expected to double water loss rates, and combined drought and warming will double reductions in anuran activity compared to warming impacts alone by 2080–2100. These findings underscore the pervasive synergistic threat of warming and environmental drying to anurans.
