This article gives an overview of the links between Earth System Models and Integrated Assessment Models (including the role of Simple Climate Models) that shape one of the main frameworks used for producing the data that feed IPCC assessments.
ESM2025
The project goal of ESM2025 is to advance the understanding of the Earth system and its response to human activities.
The project aims to develop the next generation of European Earth System Models including a more comprehensive representation of the Earth's response to anthropogenic emissions and human land-use change.
The improved models will help to enhance the consistency of climate and mitigation-relevant processes across Earth System and Integrated Assessment models and provide valuable scientific insights to support successful implementation of the
Paris Agreement.
Results from coordinated simulations with the new models will also provide more robust guidance on future global environmental risks, supporting policies targeting adaptation to global change.

The first fully-coupled methane emission driven Earth system model capable of simulating the impact of anthropgenic forcing on natural environments, as well as the impact of methane emissions and mitigation strategies on air quality.
This article gives an overview of the recent advances on the interactive modelling of ice sheet dynamics in Earth System Models, and the implications for reducing the uncertainty of sea-level rise projections, especially when considering multi-centennial timescales of changes or low-likelihood high-impact scenarios.
In this article, we provide an overview of current understanding of the land-to-ocean carbon fluxes. We describe the new conceptual model of the land-to-ocean aquatic continuum (proposed by Regnier et al, 2022, Nature), as well as ongoing work to include this new knowledge in Earth System Models.
This briefing explores the questions raised during the first ESM2025 policy forum and details the contribution of ESM2025 to various policy-relevant topics.
New study on the impacts of wildfire emissions on fine particle air pollution in the western US until the end of the 21st century, under different climate change scenarios.
This work highlights the fact that when committing to a particular level of future warming, we are also committing to a particular level of fine particle air pollution. This has to be taken into account when considering mitigation and adaptation strategies.
The Global Stocktake assesses the world’s collective progress towards achieving the purpose of the Paris Agreement and its long-term goals.
