A comprehensive database of paleoclimate records is needed to place recent warming into the longer-term context of natural climate variability. We present a global compilation of quality-controlled, published, temperature-sensitive proxy records extending back 12,000 years through the Holocene. Data were compiled from 679 sites where time series cover at least 4000 years, are resolved at sub-millennial scale (median spacing of 400 years or finer) and have at least one age control point every 3000 years, with cut-off values slackened in data-sparse regions. The data derive from lake sediment (51%), marine sediment (31%), peat (11%), glacier ice (3%), and other natural archives. The database contains 1319 records, including 157 from the Southern Hemisphere. The multi-proxy database comprises paleotemperature time series based on ecological assemblages, as well as biophysical and geochemical indicators that reflect mean annual or seasonal temperatures, as encoded in the database. This database can be used to reconstruct the spatiotemporal evolution of Holocene temperature at global to regional scales, and is publicly available in Linked Paleo Data (LiPD) format.
需要一个全面的古气候记录数据库，以便将近期的变暖纳入自然气候变化的更长期背景。我们呈现了一个经过质量控制的全球出版的温度敏感代理记录的综合汇编，这些记录可以追溯到 12000 年前的全新世。数据是从至少有 4000 年时间序列的 679 个地点汇编而来，其分辨率为亚千年尺度（中位数间隔为 400 年或更细），并且每隔 3000 年至少有一个年龄控制点，在数据稀疏的地区放宽了截止值。这些数据来自湖泊沉积物（51%）、海洋沉积物（31%）、泥炭（11%）、冰川冰（3%）和其他自然档案。该数据库包含 1319 条记录，其中包括 157 条来自南半球的记录。多代理数据库包括基于生态组合的古温度时间序列，以及反映年均或季节温度的生物物理和地球化学指标，这些指标都已在数据库中进行了编码。该数据库可用于在全球到区域尺度上重建全新世温度的时空演变，并且以链接古数据（LiPD）格式公开提供。
