Optimal High Resolution Earth System Models for Exploring Future Climate Changes

Description du projet

De nouveaux modèles du système terrestre pour améliorer l’élaboration des politiques

La surveillance et l’étude des changements climatiques à l’échelle mondiale sont essentielles pour comprendre les points de basculement du changement climatique et œuvrer à les éviter à renfort d’innovations, ou de nouvelles technologies, qui améliorent nos outils actuels. Le projet OptimESM, financé par l’UE, concevra un tel outil: une nouvelle génération innovante de modèles du système terrestre. Il combinera des processus physiques et biogéochimiques fondamentaux avec une haute résolution, générant ainsi des connaissances inédites sur le changement climatique et des outils cruciaux pour les simulations et l’élaboration de politiques concernant le climat. Cette technologie sera également utilisée pour fournir de nouvelles méthodologies sur les émissions et l’utilisation des terres, pertinentes sur le plan politique, afin d’atteindre les objectifs de l’accord de Paris.

Objectif

OptimESM will develop a novel generation of Earth system models (ESMs), combining high-resolution with an unprecedented representation of key physical and biogeochemical processes. These models will be used to deliver cutting-edge and policy-relevant knowledge around the consequences of reaching or exceeding different levels of global warming, including the risk of rapid change in key Earth system phenomena and the regional impacts arising both from the level of global warming and the occurrence of abrupt changes. OptimESM will realise these goals by bringing together four ESM groups with Integrated Assessment Modelling teams, as well as experts in model evaluation, Earth system processes, machine learning, climate impacts and science communication.

OptimESM will further develop new policy-relevant emission and land use scenarios, including ones that realise the Paris Agreement, and others that temporarily or permanently overshoot the Paris Agreement targets. Using these scenarios, OptimESM will deliver long-term projections that will increase our understanding of the risk for triggering potential tipping points in phenomena such as, ice sheets, sea ice, ocean circulation, marine ecosystems, permafrost, and terrestrial ecosystems. OptimESM will further our understanding of the processes controlling such tipping points, attribute the risk of exceeding various tipping points to the level of global warming, and develop a range of techniques to forewarn the occurrence of tipping points in the real world.

Artificial Intelligence (AI-) methods for statistical downscaling will be developed and applied to improve our understanding of the effect of long-term global change and tipping points on regional climate, particularly extreme events.
New knowledge and data from OptimESM will be actively communicated to other disciplines, such as the impacts and policy research communities, as well as the general public. This knowledge will provide a solid foundation for actionable science-based policies.
