Editorial statement
This study presents a novel global database, Wikimpacts 1.0, that leverages natural language processing and automated information extraction to systematically capture multi-scale socio-economic impacts of climate extremes over nearly a millennium. By demonstrating strong accuracy and complementary coverage to established datasets, it highlights the transformative potential of AI-driven approaches to expand, refine and democratize climate impact data for research and decision-making.

Short summary

Climate extremes threaten society and ecosystems, making impact understanding critical. Wikimpacts 1.0 provides an automated pipeline processing Wikipedia texts with underexploited information on climate impacts, yielding comprehensive socio-economic impact data for 2726 climate events from 1034–2024. It offers broader storm-related impacts and finer spatial resolution than established databases, showcasing natural language processing's potential to advance climate impact data.
