The development of large-scale artificial intelligence（AI）models has been in full swing since 2023. GraphCast，Pangu-Weather，“Fuxi”，“Fengwu” and other major global AI weather models are ushering in a new era of intelligent weather and climate forecasting. Responding to climate change is now a common challenge facing humanity，and artificial intelligence offers great opportunities to solve the global climate change issues. This paper reviews the current state of AI applications in the field of climate and summarizes the current mainstream AI weather models worldwide. Then we introduce the development of sub-seasonal-seasonal climate models，in particular the “Fengshun” big model released by the China Meteorological Administration in June 2024，which far outperforms traditional numerical models in predicting global climate anomalies. Moreover，the application and development potential of AI in the field of climate change is generally substantial，covering data assimilation and climate model improvement，climate prediction and forecasting，smart climate governance，mitigation and adaptation，energy management optimization，carbon emission monitoring，early warning of extreme disasters，disaster prevention and mitigation decision making，etc. In the context of global climate change and the intelligent era，we should establish the “1+N” AI new technology research and development in advance，and explore new intelligent governance mode of AI climate change mitigation and adaptation，so as to strategically support China’s new-generation AI development and promote global climate governance.
