Global assessment of drought characteristics in the Anthropocene

Contemporary understanding of the impacts climate change on global drought characteristics (e.g., intensities, extents) is still limited and not well understood. This knowledge critical because projected changes in are expected to impact future water availability as influence decisions how resources allocated. The main aim this study improve (extents duration) Anthropocene where rapid environment caused by composite human activities change. Multi-scale earth observation data (1980?2020) Coupled Model Intercomparison Project Phase 6 models, which incorporate Shared Socioeconomic Pathways (2040?2070 2070?2100) used assess these identify climatic hotspots could drive groundwater hydrology. Results show that towards end 21st century, land areas under will significantly decrease but their durations not. Generally, there evidence significant decline proportion experience various intensities (moderate, severe extreme drought) for each category, affected reach 30% average. Moreover, some regions potential climate-groundwater interactions events directly groundwater. varying degree strong correlations (positive negative) between Australia, Europe, Southern Africa, Asia). relatively negative indicative presence considerable lags, be aridity footprints.
