As the climate crisis intensifies, Earth system models have become increasingly significant as critical numerical simulation tools for evaluating and addressing future climate change. The Coupled Model Intercomparison Project (CMIP), aimed at promoting model development and deepening the scientific understanding of the Earth's climate system, has become a central platform for international model exchange and application. This paper provides an overview of China’s participation in the Sixth Phase of CMIP (CMIP6), including a statistical analysis of citations, research trends, and key characteristics of the Chinese Earth system models in CMIP6-related studies. In addition, the Seventh Coupled Model Intercomparison Project (CMIP7), which is currently under preparation, is briefly introduced, and the opportunities and challenges faced by China in model development are summarized. Through continuous technological innovation, international cooperation, and exchanges, Chinese scientists are expected to make greater breakthroughs in the field of Earth and Climate System Models and contribute to Chinese wisdom and solutions for global climate change response and governance.
