需要建立一个全面的古气候记录数据库，以便将最近的变暖置于自然气候变化的长期背景下。我们提出了一个全球性的汇编质量控制，出版，温度敏感的代理记录延伸到12,000年，通过全新世。数据汇编从679个网站的时间序列覆盖至少4000年，解决在亚千年尺度（中位间隔400年或更细），并至少有一个年龄控制点，每3000年，与截止值松弛在数据稀疏的地区。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157条来自南半球。多代用数据库包括以生态组合为基础的古温度时间序列，以及反映数据库中编码的年或季节平均温度的生物物理和地球化学指标。该数据库可用于重建全球到区域尺度的全新世温度时空演变，并以链接古数据（LiPD）格式公开提供。测量气候技术类型数字策展因子类型时间间隔中心点地理位置中心点代理类型样本特征-环境气候系统样本特征-位置地球（行星）机器-描述报告数据的可访问元数据文件：
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.Measurement(s)climateTechnology Type(s)digital curationFactor Type(s)temporal interval center dot geographic location center dot proxy typeSample Characteristic - Environmentclimate systemSample Characteristic - LocationEarth (planet) Machine-accessible metadata file describing the reported data:
