This project addresses some broad issues in climate change uncertainties using a 2D Integrated Science Assessment Model (ISAM). In particular, the main objectives are to (1) strengthen parametric representation in the current ISAM framework, and (2) use the strengthened ISAM framework to evaluate the impact of key feedback processes within the climate system involving atmospheric CO2, global warming, the hydrological cycle, ocean circulation, the marine carbon cycle, and their contribution to spatial and temporal changes in ocean carbon uptake. A focus will be on the investigation of possible changes in the Thermohaline Circulation (THC) and its impact on ocean biology, on the distribution of temperature and tracers in the ocean, the evolution of the atmospheric CO2 concentration, and atmospheric temperature change.ISAM results will be compared with other 2-D and 3-D atmosphere-ocean general circulation models This research has the potential to increase knowledge and understanding of physical processes that influence the concentration levels of carbon dioxide in the atmosphere. This is turn is important for assessing the role of human-induced forcing on climate change, an important societal issue.

该项目使用二维综合科学评估模型 (ISAM) 解决气候变化不确定性中的一些广泛问题。 具体而言，主要目标是（1）加强当前 ISAM 框架中的参数表示，以及（2）使用强化的 ISAM 框架来评估气候系统内关键反馈过程的影响，包括大气二氧化碳、全球变暖、水文循环、海洋环流、海洋碳循环及其对海洋碳吸收时空变化的贡献。 重点将是研究温盐环流（THC）可能发生的变化及其对海洋生物学、海洋中温度和示踪剂的分布、大气二氧化碳浓度的演变以及大气温度变化的影响。ISAM 结果将与其他 2-D 和 3-D 大气-海洋大气环流模型进行比较 这项研究有可能增加对影响大气中二氧化碳浓度水平的物理过程的认识和理解。这对于评估人为强迫对气候变化这一重要社会问题的作用也很重要。
