The main tools that are used for making projections of climate change in the coming century resulting from greenhouse-gas and other emissions are detailed coupled three-dimensional models of the atmosphere and ocean. However, such models give widely different results for some important aspects of climate change, thus limiting our ability to make practically useful projections. One such aspect is changes that may happen in the Atlantic Ocean thermohaline circulation, often referred to as the Gulf Stream. This circulation transports a great deal of heat northwards. If it weakened, future warming in Europe in particular could be reduced or possibly reversed. The spread of model results basically reflects limitations in current understanding of how the large-scale climate system operates. The aim of this project is to identify which are the most important aspects of that uncertainty by making comparisons of the responses simulated by a range of climate models. The results are intended to help improve the models by focusing attention on the aspects which require further theoretical or observational study.

用于使气候变化预测的主要工具是由温室气和其他排放造成的，这是详细的大气和海洋的三维模型。但是，这种模型在气候变化的某些重要方面给出了很大不同的结果，从而限制了我们对实际有用的预测的能力。这样的方面是大西洋热盐循环中可能发生的变化，通常称为海湾流。该循环向北运送大量热量。如果它削弱了，尤其是欧洲的未来变暖可能会减少或可能逆转。模型结果的传播基本上反映了当前对大规模气候系统运作方式的局限性。该项目的目的是通过比较通过一系列气候模型模拟的响应来确定哪些是该不确定性的最重要方面。结果旨在通过将注意力集中在需要进一步的理论或观察性研究的各个方面来帮助改善模型。
