The power and pace of climate research are being greatly increased by maximizing the volume and quality of openly accessible data. Vital sources of climate data are paleoclimate archives such as speleothems. Robust infrastructures are crucial for global analysis across time scales. Community-curated data resources have proven to be the most successful solution, establishing science-driven data standards and wide community support. The SpeleoFAIR project integrates SISAL with Neotoma and LiPD, strengthening data accessibility and governance. This aligns with broader goals of enhancing data sustainability and accelerating multi-proxy climate research analysis.
