Compilation of Cenozoic temperature proxies for terrestrial and marine surface environments

We provide a globally distributed compilation of published surface temperature proxies for eight Cenozoic time periods that cover the range of paleoclimate states. The proxies have both a marine and terrestrial provenance and are compared to the annual temperature of the same location today. This data is then used to quantify long-term temperature changes on zonal and global levels. When coupled with recent estimates of atmospheric CO2 concentration, temperature data constrains the sensitivity of Earth's climate system to perturbation of the radiative balance, with possible implications for the future response to anthropogenic forcing. The dataset consists of an excel file with eight sheets for the eight selected timeslices, namely, • mid-Pliocene (3,0 - 3,3 Ma) • late Miocene (7,2 - 11,6 Ma) • mid-Miocene (14,7 - 17,0 Ma) • early Miocene (20,3 - 23,0 Ma) • early Oligocene (27,8 - 33,9 Ma) • late Eocene (33,9 - 37,8 Ma) • middle Eocene (42 - 46 Ma) • early Eocene (48 - 55 Ma)

本数据集提供一套全球分布的已发表地表温度代用指标（surface temperature proxies），涵盖新生代（Cenozoic）的8个地质时期，覆盖各类古气候（paleoclimate）状态的区间范围。这些代用指标兼具海洋与陆地两种来源，并与对应测点现今的年平均气温进行比对。随后利用该数据集可量化纬向及全球尺度下的长期温度变化。若将该温度数据与近期发布的大气CO₂浓度估算结果相结合，便可约束地球气候系统对辐射平衡扰动的敏感性，其研究结果或可为理解人为强迫（anthropogenic forcing）下的未来气候响应提供参考依据。本数据集包含一个Excel文件，内含对应8个选定时间切片的8个工作表，分别为：
• 上新世中期（mid-Pliocene，3.0–3.3 Ma）
• 晚中新世（late Miocene，7.2–11.6 Ma）
• 中中新世（mid-Miocene，14.7–17.0 Ma）
• 早中新世（early Miocene，20.3–23.0 Ma）
• 早渐新世（early Oligocene，27.8–33.9 Ma）
• 始新世晚期（late Eocene，33.9–37.8 Ma）
• 始新世中期（middle Eocene，42–46 Ma）
• 始新世早期（early Eocene，48–55 Ma）
