ESM2025 review process is near the end. Thank you to all who shaped this project & helped make climate science more open & relevant for Europe. The knowledge & networks created through ESM2025 will continue to support climate research, education & policy long after the project ends. #ESM2025isOver

ESM2025 leaves a strong scientific legacy: open data, open code, 131+ peer-reviewed papers, and advances to tools like OS-MAGICC, used to explore emissions pathways and carbon budgets. Its insights feed into CMIP, community MIPs and future IPCC work. #ESM2025isOver

This Social Media Strategy Wheel grew out of a CRC-net 2024 meeting on social media for EU research projects, held with the contribution of @maiaresilience.bsky.social communications experts. Collective lessons from EU climate project comms and management teams, distilled into practical strategies!

ESM2025 @esm2025.bsky.social · 13/02/2026

We also engaged directly with local stakeholders through World Café workshops, bringing together practitioners, NGOs, civil servants & scientists to discuss risks, uncertainties & climate information needs. A key lesson: Engagement works best when co-designed with the stakeholders. #ESM2025isOver

Policy briefings were then prepared as summaries/follow-ups to these discussions, clarifying where the science stands and supporting the UNFCCC Global Stocktake and future IPCC assessments. A key lesson: Clustering with other EU projects helps deliver clearer messages & avoid stakeholder fatigue.

ESM2025 @esm2025.bsky.social · 08/02/2026

ESM2025 co-organised three policy fora with the European Commission, bringing together the EU comission and researchers to discuss carbon budgets, overshoot risks, land-based mitigation and the role of Earth System Models in climate policy. #ESM2025isOver

141

ESM2025 @esm2025.bsky.social · 05/02/2026

ESM2025 also created new classroom-ready resources on climate modelling and curated material from EU climate projects — helping teachers bring up-to-date science into their lessons. Another way an EU research project can strengthen climate literacy across Europe. #ESM2025isOver

ESM2025 @esm2025.bsky.social · 02/02/2026

Many participants went on to implement climate awareness, mitigation or adaptation projects in their own schools and communities — extending the impact of CESU far beyond the events themselves. A clear example of EU-level added value for education.

100

ESM2025 @esm2025.bsky.social · 02/02/2026

A standout part of ESM2025 was its investment in climate education. Through the Climate Education Summer Universities (CESUs), teachers from across Europe met researchers, explored climate processes and uncertainties, and exchanged approaches to climate teaching. #ESM2025isOver

ESM2025 @esm2025.bsky.social · 01/02/2026

In strong net-negative scenarios, some models showed unexpected ocean circulation responses, influencing how much cooling occurs per tonne of CO₂ removed. A reminder that overshoot recovery depends on Earth-system feedbacks, not just emissions curves.

ESM2025 @esm2025.bsky.social · 01/02/2026

ESM2025 explored climate behaviour after net-zero CO₂. Cumulative emissions remain a strong predictor of warming, but small deviations can shift when temperatures peak — a critical insight for assessing overshoot pathways. #ESM2025isOver

ESM2025 @esm2025.bsky.social · 28/01/2026

To explore these budgets and pathways more realistically, ESM2025 supported the move toward emission-driven CO₂ experiments in the next CMIP cycle, helping connect socio-economic pathways directly to Earth-system responses when assessing future mitigation strategies.

111

ESM2025 @esm2025.bsky.social · 28/01/2026

ESM2025 reinforced the basis for carbon budgets, confirming how closely global warming tracks cumulative CO₂ emissions. It also showed how non-CO₂ gases, especially CH₄, can shift the timing and scale of Paris-compatible pathways — a key nuance for 1.5°C and 2°C planning. #ESM2025isOver

Modelling Ice sheets in Earth System Models: pushing the boundaries of our scientific and technical capabilities

Recent advances on the interactive modelling of ice sheet dynamics in Earth System Models.

ESM2025 @esm2025.bsky.social · 24/01/2026

ESM2025 also moved towards including land-to-ocean carbon fluxes directly in Earth System Models, by coupling inland-water processes into a land surface scheme and assessing how human activities since 1850 have altered riverine carbon exports. #ESM2025isover

121

ESM2025 @esm2025.bsky.social · 19/01/2026

This work shows that a large share of the carbon leached from land is transformed or returned to the atmosphere before reaching the open ocean, and helps close the global carbon budget by clarifying where and how those fluxes occur.

100

ESM2025 @esm2025.bsky.social · 19/01/2026

Carbon doesn’t flow straight from land to the open ocean. In ESM2025, we have used the land-to-ocean aquatic continuum (LOAC) framework to follow carbon through rivers, floodplains, lakes, estuaries and coastal waters – and to quantify what happens along the way. #ESM2025isOver

ESM2025 @esm2025.bsky.social · 16/01/2026

By improving how fires are represented in Earth System Models, ESM2025 helps reveal whether wildfire regimes amplify or dampen regional warming, and how smoke and particles affect pollution and atmospheric processes – key for assessing climate and environmental risks. #ESM2025isOver

120

ESM2025 @esm2025.bsky.social · 13/01/2026

The project strengthened links between fire, vegetation growth and carbon cycling, and explored how future fire patterns may change under different climate and land-use conditions.

100

ESM2025 @esm2025.bsky.social · 13/01/2026

Wildfires are increasing in many regions due to climate change, land use and vegetation dynamics. ESM2025 improved how fire dynamics are simulated in Earth System Models, including their effects on carbon emissions, air quality and ecosystems. #ESM2025isOver

ESM2025 @esm2025.bsky.social · 11/01/2026

These developments strengthen the basis for exploring future changes in ocean heat content, carbon storage, marine greenhouse gas emissions and their climate feedbacks.

020

ESM2025 @esm2025.bsky.social · 11/01/2026

ESM2025 also advanced marine biogeochemical modelling. Improvements to ocean carbon and nitrogen cycles, and to marine N₂O emissions, help capture how deoxygenation and nutrient dynamics feed back on climate. #ESM2025isOver

ESM2025 @esm2025.bsky.social · 07/01/2026

These refinements improve simulations of vertical heat and nutrient transport, stratification, and large-scale circulation features. In CNRM-ESM, better eddy-induced circulation even reduced biases in sea surface temperature and subsurface structure. 👉End-of-project news article: bit.ly/48hsZYg

ESM2025 comes to an end: a new generation of Earth system models for climate action

ESM2025 officially ends on 30 November 2025 after four and a half years developing a new generation of “mitigation-oriented” Earth system models to better link emissions, climate responses and policy-relevant pathways.

010

ESM2025 @esm2025.bsky.social · 07/01/2026

The ocean absorbs and redistributes vast amounts of heat and carbon. In ESM2025, ocean models used for climate projections gained more realistic convection and eddies, improving how vertical motions and circulation are represented. #ESM2025isOver

110

ESM2025 @esm2025.bsky.social · 29/12/2025

Ice-sheet changes unfold over centuries, which means sea level continues to rise long after temperatures stabilise. ESM2025 helped clarify these long-term feedbacks by improving how ESMs simulate ice–ocean–climate interactions and the processes behind committed sea-level change. #ESM2025isOver

121

ESM2025 @esm2025.bsky.social · 23/12/2025

Key processes such as surface mass balance, dynamic ice flow and ice–ocean melt are now represented. This creates a stronger basis for exploring ice–climate feedbacks and long-term sea-level risks, including under overshoot scenarios. #ESM2025isOver

110

ESM2025 @esm2025.bsky.social · 23/12/2025

Ice sheets are a major source of long-term sea-level rise. ESM2025 improved how Earth System Models represent them by enabling dynamical ice-sheet components in UKESM and IPSL-ESM. These models can now simulate ice-sheet evolution in response to climate forcing & its influence on global sea level.

102

ESM2025 @esm2025.bsky.social · 17/12/2025

By linking nitrogen flows across ecosystems, agriculture and the atmosphere, these advances help explore trade-offs between food production, mitigation strategies and environmental goals in future scenarios.

110

ESM2025 @esm2025.bsky.social · 17/12/2025

ESM2025 also developed a new model for agricultural ammonia emissions, covering all stages from animal housing to fertiliser use. Applied to future livestock scenarios, it projects strong NH₃ increases under some pathways, with consequences for air quality, nitrogen deposition and climate feedbacks.
