地球温暖化および関連する人為起源の環境変化により、極端な気象現象の激甚化や海面上昇、海洋酸性化・貧酸素化、そして大規模な生態系変化が生じることが懸念されている。こうした変化を予測するための気候変動予測国際プロジェクト(CMIP6)は、大きな社会的反響を呼んだIPCC第6次報告書（AR6）に大きく貢献した． CMIP6の他にも、イベントアトリビューションや、環境変化と社会経済の相互作用を取り入れたモデル開発、「地球デジタルツイン」を標榜した超高解像度モデル開発など、様々なタイプの予測研究が盛んになっている。本セッションでは、地球規模環境変化予測に関する専門的な議論に加え、モデル予測と観測、社会科学との分野横断的な連携も視野に、最新の研究成果報告と討議を行う。想定される次期の予測プロジェクトCMIP7に向けたモデル開発の方向性や、さらにその先を見据えた高解像度モデル開発についての発表も歓迎する．

Anthropogenic forcings on the global environment are expected to cause intensification of extreme events, such as sea-level rise, hurricanes and typhoons, ocean acidification, and deoxygenation, as well as regional-scale ecosystem changes. Under the international project CMIP6, Earth System modeling groups across the world performed simulations and published projection data, which made invaluable contributions to the 6th IPCC assessment report (AR6) published in August 2021, which attracted much attention from the general public and policymakers. Other than CMIP6, new types of studies, such as event attribution, coupling of socio-economic processes and Earth system dynamics, and realistic high resolution modeling advocating "Digital Twin Earth" are emerging in the field of global change predictions and projections. In addition, analysis of observational data is becoming increasingly important for assessing the credibility of model projections of the global environment. Interactions and collaborations beyond the boundaries of conventional scientific disciplines are desired for dealing with the issue of global changes and their societal impacts. This session hosts the latest research findings with a view to modeling global-to-regional projections and interdisciplinary collaborations including those with social sciences. Presentations on the direction of model development for the upcoming CMIP7, and ultra-high-resolution modeling that extends the frontiers further, are also welcome.
