Age and alkenone-derived Holocene sea-surface temperature records of sediment core M40-4-SL78

This Special Issue of The Holocene contains 16 research papers based on a symposium at the 11th International Meeting of the European Union of Geosciences held in Strasbourg in April 2001. The aim of the symposium was a state-of-the-art assessment of empirical studies of postglacial marine and terrestrial climatic archives and their integration with numerical climate models. This editorial places the individual papers in the broader context of natural climate variability and anthropogenic impacts on the global climate system, regional differences in climate between maritime and continental areas, and the need for an improved theoretical basis for understanding the underlying causes of environmental change. The focus of the Special Issue is the dynamic and relatively well-understood climate of the North Atlantic and the European realm, where, in relation to the steepest offshore temperature gradient on Earth, observational data are abundant and many recent advances have been made in climate reconstruction from proxy archives. The editorial also contains a summary and overview of the papers included in the four main sections of the Special Issue, which emphasize: (1) numerical modelling experiments; (2) models of glacier buildup and equilibrium-line altitude; (3) marine and terrestrial proxy records of climatic change; and (4) multiproxy palaeoenvironmental reconstruction of a Portuguese lagoonal system.

《全新世》这一特刊收录了16篇研究论文，这些论文基于2001年4月在斯特拉斯堡召开的欧洲地球科学联盟第11届国际会议上的一场研讨会。该研讨会旨在对冰后期海洋与陆地气候档案的实证研究及其与数值气候模型的整合进行前沿评估。本社论将各篇论文置于更广阔的背景下，涵盖自然气候变率与人为因素对全球气候系统的影响、海洋性与大陆性区域间的气候差异，以及为理解环境变化根本原因而完善理论基础的必要性。该特刊聚焦于北大西洋与欧洲区域动态且相对已被充分理解的气候系统；在此区域，由于存在地球上最陡峭的近海温度梯度，观测数据十分丰富，且近年来利用代用档案（proxy archives）进行气候重建的研究取得了诸多进展。社论还包含对特刊四个主要部分所收录论文的总结与概述，这些部分重点关注：（1）数值模拟实验；（2）冰川累积与平衡线高度模型；（3）气候变化的海洋与陆地代用记录；（4）葡萄牙潟湖系统的多代用指标古环境重建。
