当前的气候变化鼓励了跨学科合作，以更好地了解气候在过去地中海社会发展中可能发挥的作用。近二十年来，地中海的古环境研究取得了重大进展，主要基于海洋、湖泊、沼泽、泥炭沼泽和河流档案。这些记录显示了人类对地中海生态系统的长期影响，但也提供了显著的气候不稳定的证据，在全新世（9.2、8.2、6-5、4.2、3.2 ka cal. BP）期间，全球范围内出现了显著的快速气候变化（RCC）时期（公元前7.2、6.2、4-3、2.2、1.2 ka）。对上一千年气候的研究是特别有趣的，因为这一时期包括了最近的前工业化时期的暖期，即中世纪气候异常期，随后是小冰河期最冷的几个世纪，在1850年左右被工业时代打断。在产生替代信号方面取得重大进展的同时，耦合模式比对项目（CMIP）中使用最先进的海洋-大气耦合模式对上一千年气候进行模式模拟，允许对代理数据和模式数据进行交叉分析，以探索起作用的物理机制以及太阳活动、火山活动、土地利用和温室气体等外部因素在气候变率中的作用。IRD_SYN_HC_Q_COP22_Part_1。气候变化下的地中海地区
The current climate change has encouraged interdisciplinary collaboration to better understand the role that climate may have played in the development of past Mediterranean societies. Over the past twenty years, palaeoenvironmental research in the Mediterranean has progressed significantly, mainly based on marine, lake, marsh, peat bog and fluvial archives. These records demonstrate the long anthropogenic impact on the Mediterranean ecosystems but also provide evidence of significant climatic instability with notable periods of rapid climate change (RCC) at the global scale during the Holocene (9.2, 8.2, 6-5, 4.2, 3.2 ka cal. BP (c. 7.2, 6.2, 4-3, 2.2, 1.2 ka BC). The study of the climate in the last millennium is of particular interest because this period encompasses the most recent pre-industrial warm interval known as the Medieval Climate Anomaly followed by the coldest centuries of the Little Ice Age, which was interrupted around 1850 by the industrial era. In parallel with major progress in generating proxy signals, model simulations of the climate in last millennium using stateof-the-art coupled ocean-atmosphere models in the Coupled Model Intercomparison Project (CMIP) allow cross-analyses of proxy and model data to explore the physical mechanisms at play and the role of external factors like solar activity, volcanism, land use and greenhouse gases in climate variability.
