This award will support the creative integration of paleoclimate research and educational outreach to better understand the interplay of low- and high-latitude climate processes in Earth's natural climate evolution and to describe this interplay in a manner useful to social scientists engaged in the economic and policy aspects of global climate change. In general, the researcher will use a series of numerical experiments to examine how orbital forcing of low latitude tropical climates might impact high latitude ice sheet growth during the Quaternary Ice Ages and the occurrence of climatic events such as the El Nino-Southern Oscillation (ENSO). Specifically, the researcher will pursue a scientific strategy to investigate the physical processes involved in the response of the tropical climate to orbital forcing, compare purely orbital signatures with glacial stage signatures in tropical climate, investigate the relative effects of orbital and glacial forcing on variability within tropical climates, and investigate how the telconnection between low and high latitudes might be altered as the mean climate state changes (i.e., when ice cover and atmospheric levels of CO2 change).The researcher's long-term scientific goals are complemented by a near-term educational goal of contributing a quantitative paleoclimatic perspective to the development of a university-wide undergraduate course covering the scientific, economic, and social aspects of climate change.

该奖项将支持将古气候研究和教育宣传创造性地结合起来，以更好地了解低纬和高纬度气候过程在地球自然气候演变中的相互作用，并以对从事全球气候变化的经济和政策方面的社会科学家有用的方式描述这种相互作用。总的来说，研究人员将利用一系列数值实验来研究低纬热带气候的轨道强迫如何影响第四纪冰期高纬度冰盖的增长，以及厄尔尼诺-南方涛动(ENSO)等气候事件的发生。具体地说，研究人员将实施一项科学战略，调查热带气候对轨道强迫的反应所涉及的物理过程，将热带气候的纯轨道特征与冰川阶段特征进行比较，调查轨道和冰川强迫对热带气候内可变性的相对影响，并调查低纬度和高纬度之间的远程联系如何随着平均气候状态的变化而改变(即当冰盖和大气二氧化碳水平变化时)。研究人员的长期科学目标与近期教育目标相辅相成，即为大学范围内涵盖科学、经济、以及气候变化的社会方面。
