Short summary

We present a database of databases (DoD2k) and toolkit (DT2k) for Common Era (1–2000 A.D.) paleoclimate research. DoD2k contains 4781 unique records assembled from 5 curated databases using DT2k. We analyze for common features across moisture and temperature sensitive records, and we test cave carbonate data simulations against observations. DoD2k is expected to be useful for attributing climate change on decadal timescales and for improving data models and paleoclimate reconstructions.
