Antarctic Penisula Climate Variability: A Historical and Paleoenvironmental Perspective

该奖项由国家科学基金会（NSF）极地项目办公室（Office of Polar Programs）提供，沿着汉密尔顿学院环境研究项目的配套资金，为将于2001年9月在汉密尔顿学院举行的研讨会提供支持。除美国外，来自其他几个国家的科学家也将参加该讲习班，他们积极参与该区域的环境研究。此外，讲习班还将采取跨学科的办法，了解南极半岛地区正在发生的环境变化。在过去的几十年里，南极半岛的生态系统和物理环境发生了严重而迅速的变化，在最近的IPCC（政府间气候变化专门委员会）报告中，该地区是气温上升趋势最强烈的区域“热点”。包含温室气体和硫酸盐气溶胶的全球气候模型显示出与观测到的温度趋势惊人的一致性。研讨会将讨论这一对应关系，并将把历史数据纳入过去12 000年来气候变化的地质和冰川记录的背景中。将在十年至千年的时间尺度上讨论和审查海洋学和大气的联系。在编辑委员会核准之前，研究结果将在《南极研究丛刊》合订本中发表。

This award, provided by the Office of Polar Programs (OPP) of the National Science Foundation (NSF), provides support, along with matching funds from the Environmental Studies Program at Hamilton College, for a workshop to be held at Hamilton College in September of 2001. The workshop will involve scientists from several other countries, in addition to the United States, who are actively involved in environmental research in the region. In addition, the workshop will take an interdisciplinary approach to understanding the environmental changes taking place in the region of the Antarctic Peninsula. The past several decades have demonstrated severe and rapid changes in the ecosystems and physical environment of the Antarctic Peninsula and the region stands out in the most recent IPCC (Intergovernmental Panel on Climate Change) report as the strongest regional "hot spot" for increased temperature trends. Global climate models that incorporate greenhouse gases and sulfate aerosols demonstrate a striking correspondence to the observed temperature trends. The workshop will address this correspondence and will place historical data into the context of geological and glaciological records of climate change over the last 12,000 years. Oceanographic and atmospheric linkages will be discussed and examined for decadal to millennial time scales. The results will be published in a bound volume of the Antarctic Research Series, pending approval by the editorial committee.
