The role of climate modelling groups in the development of international agreements that aim to assess future climatic risks and limit greenhouse gas concentrations is not well recognised. It is arguable that no such agreements would have been possible without carefully designed and managed research programs that provided the data upon which these risks and thus, decisions were made. Many groups contributed data that underpinned the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report published in 2014 that led to the ground-breaking Paris Agreement. Australia’s contribution included the results of a CSIRO climate model which had its genesis in a relatively simple weather forecast model two decades previously. Two people were mainly responsible for the modelling program which led to this accomplishment—Barrie Hunt and Hal Gordon. A brief history of the program is described here and. Examining some basic metrics reveals some surprising impacts.

气候建模小组在制定旨在评估未来气候风险和限制温室气体浓度的国际协议中的作用尚未得到充分认识。可以说，如果没有精心设计和管理的研究计划，这些计划提供了这些风险和决策所依据的数据，就不可能达成这样的协议。许多团体提供了数据，为 2014 年发布的政府间气候变化专门委员会 （IPCC） 第五次评估报告提供了数据，该报告促成了开创性的《巴黎协定》。澳大利亚的贡献包括 CSIRO 气候模型的结果，该模型起源于二十年前一个相对简单的天气预报模型。两个人主要负责建模程序，从而取得了这一成就，他们是 Barrie Hunt 和 Hal Gordon。此处介绍了该计划的简要历史。检查一些基本指标会发现一些令人惊讶的影响。
