This paper introduces a proof-of-concept system that combines a curated knowledge graph with AI agents to overcome persistent barriers in climate data science, such as fragmented datasets and high technical skill requirements. By enabling natural-language interaction, automated data access, and cloud-native workflows, the system lowers entry barriers, improves reproducibility, and demonstrates how a knowledge-graph-driven approach can democratize climate data science and support scalable human–AI collaboration.
