本文综述了末次冰盛期地表温度场的模型和基于代理的重建方法的研究进展。这两种方法都已汇聚到比现在冷得多的气候状态，温度距平场显示出强烈的极地放大和陆海对比。大范围变化的幅度越来越受到很好的限制，最近的一次模式数据综合产生了4摄氏度的值，这表明中等平衡的气候敏感度约为2.5摄氏度。然而，仍然存在重大的不确定性领域，特别是在热带海洋表面温度变化方面。在更精细的次大陆空间尺度上，模型和数据之间关于变化模式的一致性有限。
We review progress in model and proxy-based reconstruction of the surface temperature field of the Last Glacial Maximum. Both approaches have converged towards a climate state substantially colder than the present day, with the temperature anomaly field showing strong polar amplification and land-sea contrast. The magnitudes of the large-scale changes are increasingly well-constrained, with a recent model-data synthesis generating a value of 4 °C, which suggests a moderate equilibrium climate sensitivity of about 2.5 °C. However, significant areas of uncertainty remain, particularly in the tropical sea surface temperature change. At finer sub-continental spatial scales, there is limited agreement between models and data regarding the patterns of change.
