2021~2023年全球气候变化科学评估进展

Abstract:From 2021 to 2023，the Intergovernmental Panel on Climate Change（IPCC）issued three working group reports and a synthesis report of the Sixth Assessment Report on Climate Change（AR6），which had an important impact on the global climate governance process. The World Meteorological Organization（WMO）also publishes annual global climate reports and regional climate reports every year，providing authoritative scientific information on the climate system and its changes for the international community. The Future Earth（FE）has set up The Earth Commission（EC）to evaluate the Earth life support systems（such as water resources，land，ocean，biodiversity，etc.）to ensure that the Earth system is in a stable and resilient state. This paper summarizes the progress of global climate change scientific assessment of IPCC，WMO and FE，summarizes the current global climate change status，trends and mitigation pathways，and give reviews and prospects of the scientific assessments of climate change.
