Reproducible climate reconstructions of the Common Era (1 CE to present) are key to placing industrial-era
warming into the context of natural climatic variability. Here we present a community-sourced database of
temperature-sensitive proxy records from the PAGES2k initiative. The database gathers 692 records from
648 locations, including all continental regions and major ocean basins. The records are from trees, ice,
sediment, corals, speleothems, documentary evidence, and other archives. They range in length from 50 to
2000 years, with a median of 547 years, while temporal resolution ranges from biweekly to centennial.
