The results of the sixth phase of the coupled model intercomparison project (CMIP) are currently being analyzed and will form the basis of the IPCC Sixth Assessment Report. Since its creation in the mid‐1990s, CMIP has had an increasing influence on climate research. While the principle behind it has always remained the same—comparing different climate models under similar conditions—its design and motivations have evolved significantly over the phases of the project. This evolution is closely linked to that of the IPCC since, historically as well as today, the results of CMIP have played a major role in the Panel's reports. This role increased the visibility of CMIP. Over time, more and more people started to be interested in CMIP and to analyze its results. Despite this success, the way CMIP is used today raises methodological issues. In fact, CMIP has promoted a particular way of doing climate research, centered on a single tool–Global Coupled Models (GCMs)–and creating a gap between model developers and model users. Due to the debates regarding the interpretation of multi‐model ensembles and the validation of GCMs, whether the emphasis on this particular way of studying climate is serving the progress of climate science is questionable.

耦合模型比对项目：气候研究的历史，用途和结构影响

耦合模型比较项目（CMIP）第六阶段的结果目前正在分析中，并将成为IPCC第六次评估报告的基础。自1990年代中期创建以来，CMIP对气候研究的影响越来越大。尽管其背后的原理始终保持不变（在相似的条件下比较不同的气候模型），但其设计和动机在项目的各个阶段都发生了重大变化。这种发展与IPCC的发展密切相关，因为从历史上到今天，CMIP的结果在小组的报告中都发挥了重要作用。该角色提高了CMIP的可见性。随着时间的流逝，越来越多的人开始对CMIP感兴趣并分析其结果。尽管取得了成功，但今天使用CMIP的方式仍引起方法论问题。实际上，CMIP促进了一种进行气候研究的特殊方法，该方法以单一工具-全球耦合模型（GCM）为中心-并在模型开发人员和模型用户之间造成了鸿沟。由于关于多模型集合的解释和GCMs验证的争论，对这种研究气候的特殊方式的重视是否对气候科学的发展是有益的。
