Abstract:

The Intergovernmental Panel on Climate Change (IPCC) has accomplished all the assessment reports of the sixth assessment cycle (AR6). The synthesis report “Climate Change 2023” offers solid scientific support for the first Paris Agreement Global Stocktake, forming the “United Arab Emirates (UAE) Consensus” that guides global climate governance. Currently, both the IPCC and the Global Stocktake have embarked on a new cycle, and their work arrangements also basically coincide with the timeline of China’s “dual carbon” goals of “achieving carbon peak before 2030”. To better exert China’s leading role in global climate governance and gain the initiative in international climate governance from a scientific perspective, this paper commences from the major assessment achievements of the IPCC AR6 and the future planning of the AR7, combs through the cutting-edge scientific issues closely related to the Global Stocktake in the IPCC scientific assessment, and puts forward important insights such as scientifically promoting the transformation of the energy structure, paying attention to the security of energy and climate; highly valuing the assessment and reduction of non-CO₂ gases; strengthening adaptation actions, promoting the construction of adaptive cities; paying attention to climate tipping points, actively responding to new challenges of extreme climates, etc. It also presents development suggestions for the future in the fields of climate change mitigation, adaptation, and the natural science foundation. It is hoped to provide reference for our country to fully participate in the new round of IPCC climate change assessment and global climate governance.

Key words: Global Stocktake, Assessment of climate change, Global climate governance
