A Workshop on Deep-Time Paleoclimatology, to be held May 16-17, 2003, Arlington, VA

关于深层古气候学的研讨会(EAR-0323841)Gerilyn Soreghan，Christopher Maples，Judith Parrish-Jones地球的“深层”岩石记录保存了多次大规模环境变化实验的结果，并延续到其40亿年的历史。尽管对最近气候状态的研究可以捕捉到深度研究中通常缺乏的分辨率，但它们无法捕捉到气候系统行为的广度。相比之下，深度时间研究展示了地球现代或最近(200万年)记录中未知的环境扰动，以及发生在更长时间尺度上的反馈，以及对不同扰动的反应，而不是最近观察到的扰动。此外，适用于深度气候研究的分析技术的重大进步使研究人员能够在我们对气候系统行为的理解方面取得长足进步。需要资金来举办一次讲习班，讨论深部古气候学的科学问题，以便确定那些可以深入研究和理解的基本气候系统问题。尽管一些可以深入研究的过程可能会超过人类的时间尺度，但通过反馈和阈值，它们可以影响那些确实在人类时间尺度上运行的气候过程。在我们能够理解这些过程之前，我们在较短时间尺度上理解气候的能力仍将存在差距，从而导致气候预测的不确定性。这次讲习班将有助于我们对地球气候系统动态的最终了解和描述，为今后深入研究古气候学开展对话和提出建议。

A Workshop on Deep-Time Paleoclimatology (EAR-0323841)Gerilyn Soreghan, Christopher Maples, Judith Parrish-JonesABSTRACTEarth's "deep-time" rock record preserves the results of multiple large-scale experiments in environmental change, and extends well into its 4 billion-year history. Although studies of recent climate states can capture a resolution commonly lacking in deep-time studies, they fail to capture the breadth of climate-system behavior. In contrast, deep-time studies showcase environmental disturbances unknown from Earth's modern or recent (2,000,000 yr) record, as well as feedbacks that occur on longer time scales, and in response to different perturbations, than those observable from the recent. Furthermore, significant advances in analytical techniques applicable to deep-time climate studies are enabling researchers to make great strides in our understanding of climate-system behavior. Funds are requested to convene a workshop to discuss the science of deep-time paleoclimatology in order to define those fundamental climate-system problems that can be uniquely studied and understood in deep time. Although some of the processes that can be studied in deep time may exceed human time scales, through feedbacks and thresholds, they can affect those climate processes that do operate on human time scales. Until we can understand these processes, gaps in our ability to understand climate on shorter time scales will remain, contributing to climate-prediction uncertainty. This workshop will contribute to our ultimate understanding and characterization of climate-system dynamics on Earth by initiating a dialogue and recommendations for the future pursuit of deep-time paleoclimatology.
