The effects of greenhouse warming are expected to be much greater in the arctic regions of both hemispheres than at low latitudes. In order to fully understand and predict the effects of such a warming at high latitudes, it is necessary to reconstruct the history of climate on the continents and over the oceans in the Arctic. The goal of this project is to reconstruct the glacial-interglacial history of climate in a region where, at present, there is a significant sparsity of paleoclimate information: the regions of Alaska and Siberia known as Beringia. Through a series of cooperative field programs, researchers from the US and USSR will collaborate on paleoecological, paleoclimatological and paleolimnological analyses which will determine both the history of climate change in this region and its effects on the local ecology. This project is important because it will help to identify and quantify the natural range and rates of change in climate in regions where significant changes are predicted for the future.

预计温室气体变暖对两个半球的北极地区的影响要比低纬度地区大得多。为了充分了解和预测这种气候变暖对高纬度地区的影响，有必要重建北极大陆和海洋的气候历史。这个项目的目标是重建一个目前古气候信息非常稀少的地区的冰川-间冰期气候历史：阿拉斯加和西伯利亚地区被称为Beringia。通过一系列合作实地项目，美国和苏联的研究人员将在古生态、古气候学和古湖泊分析方面进行合作，这些分析将确定该地区气候变化的历史及其对当地生态的影响。这个项目很重要，因为它将有助于确定和量化预测未来发生重大变化的地区气候变化的自然范围和速度。
