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2D综合科学评估模型（ISAM）解决了气候变化不确定性的一些广泛问题。 特别是，主要目标是（1）加强当前ISAM框架中的参数表示，并且（2）使用加强的ISAM框架来评估涉及大气CO2，全球变暖，海水循环，海洋碳周期，海洋碳周期及其对海洋和临时上升的贡献的气候系统中关键反馈过程的影响。 将重点放在研究热呼气循环（THC）及其对海洋生物学的影响，对海洋温度和示踪剂的分布，大气CO2浓度的演变以及大气温度变化的影响。将与其他2-D和3-D大气环境循环模型进行比较，这可能会增加型号的养育水平。这对于评估人类引起的强迫对气候变化的作用是重要的，这是一个重要的社会问题。
