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》（The Holocene）本期特刊收录16篇研究论文，均基于2001年4月在斯特拉斯堡举办的欧洲地球科学联盟（European Union of Geosciences）第11届国际会议期间的研讨会成果。本次研讨会的核心目标是对冰期后海洋与陆地气候代用档案的实证研究开展前沿水平的综合评估，并探讨其与数值气候模型（numerical climate models）的整合路径。本编辑部导言将各篇论文置于更广阔的研究语境中：涵盖自然气候变率、人为活动对全球气候系统的影响、海洋性与大陆性区域间的气候区域差异，以及为理解环境变化深层成因而亟需完善的理论基础等维度。本期特刊的研究聚焦于北大西洋及欧洲区域的动态且认知相对充分的气候系统——该区域拥有全球最陡峭的近海温度梯度，观测数据极为丰富，且基于代用气候档案（proxy archives）开展气候重建的研究已取得多项新近进展。本导言还对本期特刊四大主题板块收录的论文进行了总结与概览，四大板块的研究重点分别为：(1) 数值模拟实验；(2) 冰川发育与平衡线高度（equilibrium-line altitude）模型；(3) 气候变化的海洋与陆地代用记录；(4) 葡萄牙泻湖系统的多代用指标古环境重建。
