Abstract

Ongoing global warming due to anthropogenic climate change has long been recognized, yet uncertainties regarding how seasonal extremes will change in the future persist. Paleoseasonal proxy data from intervals when global climate differed from today can help constrain how and why the annual temperature cycle has varied through space and time. Records of past seasonal variation in marine temperatures are available in the oxygen isotope values of serially sampled accretionary organisms. The most useful data sets come from carefully designed and computationally robust studies that enable characterization of paleoseasonal parameters and seamless integration with mean annual temperature data sets and climate models. Seasonal data sharpen interpretations of—and quantify overlooked or unconstrained seasonal biases in—the more voluminous mean temperature data and aid in the evaluation of climate model performance. Methodologies to rigorously analyze seasonal data are now available, and the promise of paleoseasonal proxy data for the next generation of paleoclimate research is significant. Expected final online publication date for the Annual Review of Earth and Planetary Sciences, Volume 50 is May 2022.

解读地球古代海洋的温度季节性

由于人为气候变化导致的持续全球变暖早已被认识到，但关于未来季节性极端天气将如何变化的不确定性仍然存在。来自全球气候与今天不同时期的古季节代用数据可以帮助限制年温度周期如何以及为什么随时间和空间而变化。在连续取样的增生生物的氧同位素值中可以得到过去海洋温度季节变化的记录。最有用的数据集来自精心设计和计算稳健的研究，这些研究能够表征古季节参数，并与年平均温度数据集和气候模式无缝整合。季节数据在更大量的平均温度数据中加强了对被忽视或不受约束的季节偏差的解释和量化，并有助于评估气候模式的性能。现在有了严格分析季节数据的方法，古季节代用数据对下一代古气候研究具有重要意义。《地球与行星科学年度评论》第50卷的最终在线出版日期预计为2022年5月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。
