History of Forcing Significance of GISP2 Record

Mayewski, Paul A.和Meeker， Loren D.新罕布什尔大学GISP2记录的强迫意义越来越多的人认识到冰芯提供的特殊的“过去窗口”。特别是，在Summit Greenland完成的深度钻探为古气候学家提供了年代准确、分辨率高、多参数的记录，为研究末次冰期/间冰期旋回的气候变化提供了前所未有的视角。该奖项支持的项目侧重于：(1)利用多变量（如同位素、颗粒、化学）GISP2记录开发更可靠的古气候描述；(2)利用GISP2作为与其他古气候记录比较的框架；(3)建立大气环流系统的替代记录，以研究季节-年际和十年-百年尺度的变化；(4)调查和解释GISP2记录的化学物质来源和生产速率的变化，以促进我们对生物地球化学循环的认识；(5)通过对全新世气候变化（如大气环流、干旱、生物活动的变化）和强迫的详细描述，加深对全新世气候复杂行为的认识；(6)研究近全新世气候的类似物，包括间冰期、间冰期和间冰期的过渡，以进一步阐明全新世气候的响应和强迫；(7)研究气候变化事件的全球分阶段；(8)研究气候的自然强迫和人为强迫，以加强对未来气候的预测；(9)根据人类对气候变化的影响来解释上述内容。

Abstract ATMP-9706921 Mayewski, Paul A., and Meeker, Loren D. University of New Hampshire History of forcing Significance of GISP2 Record There is growing recognition of the special "window on the past" provided by ice cores. In particular, completion of deep drilling at Summit Greenland has presented paleoclimatologists with a well-dated, high resolution, multi-parameter record which is providing an unprecedented view of climate change over the last glacial/interglacial cycle. This award supports a project focused on: (1) developing even more robust descriptions of paleoclimate utilizing the multivariate (e.g., isotopes, particles, chemistry) GISP2 record; (2) utilizing the GISP2 as a framework for comparison with other paleoclimate records; (3) developing proxy records for atmospheric circulation systems in order to investigate seasonal-to-interannual and decadal-to centennial scale variability; (4) investigating and interpreting changes in the sources and production rates of the chemical species recorded in the GISP2 record in order to contribute to our understanding of biogeochemical cycling; (5) enhancing our understanding of the complex behavior of Holocene climate through the detailing of Holocene climate change (e.g., changes in atmospheric circulation, aridity, biological activity) and forcing; (6) investigating analogs for near-Holocene climate including interstadials, Eem and transitions into and out of stadials to further elucidate Holocene climate response and forcing; (7) investigating global phasing of climate change events; (8) investigating natural versus anthropogenic forcing of climate to enhance prediction of future climate and; (9) interpreting the preceding in light of the human dimensions of climatic change.
