Have you ever wondered how to better engage Early Career Researchers in a research project?

We're glad we had so many ECRs across Europe answering our survey. We hope our recommendations will help future EU projects better support ECRs. says Mariana Rocha, about the White Paper on how EU climate research projects better can support ECRs. optimesm-he.eu/2026/06/15/b... #OptimESM #ECR

Ever wished you could give your younger self some advice? 🤔 At one of our Climate Research Communication Network meetings, communication officers, project managers & engagement leads from EU climate research projects shared useful insights. Here’s what they shared 👇 #ClimateResearchNet

❓When tipping causes tipping Ocean currents, monsoons, rainforests, ice sheets – all talk to each other Next week Anna von der Heydt @utrechtuniversity.bsky.social explains how such #climatetippingelements interact using paleoclimate clues🧩 Join us 3 Mar 2–3pm CET bit.ly/climtip-webi... #ClimTip

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!

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

Check out this great community-built resource on how to make social media work for your research project!

🛞CRC-net Social Media Strategy Wheel: “Make social media work for your EU project” is an open resource built from the collective experience of EU climate project communication and management teams. #ClimateResearchNet Thanks @climtip.bsky.social @esm2025.bsky.social for the infographics!

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

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

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 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 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

🥵 2024 El Niño pushed us over 1.5°C, making it the hottest year on record: heatwaves floods hunger for +110 mln people $3.4 trn in costs Could such extremes trigger tipping points too? @aromanou.bsky.social #NASA explains in next #ClimTipWebinar Join 👉 3 Feb 2–3pm CET bit.ly/climtip-webi...

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

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

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

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 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

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

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

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.

Nitrogen was another key part of ESM2025. The project improved how terrestrial nitrogen cycles are coupled with land models, so we can better simulate how N availability affects plant growth, carbon uptake and N₂O emissions – including nitrogen released from thawing permafrost. #ESM2025isOver

ESM2025 strengthened how Earth System Models represent methane — from wetland emissions to the atmospheric chemistry that sets CH₄ lifetime. Models now respond more realistically to temperature, moisture and chemical changes. #ESM2025isOver

Land-based mitigation isn’t just about carbon. ESM2025 helped underline how biogeophysical effects shape the climate impact of forests. 👇🧵 #ESM2025isOver

🌱 Land-based mitigation (afforestation, reforestation, BECCS) features prominently in many climate pathways. ESM2025 looked at how current Earth System Models respond to large-scale land-based CDR, and what that means for climate. #ESM2025isOver

Warming is accelerating. Tipping risks increasing. Net zero may not stop temperature rise. ‼️ Our joint policy brief outlines what new Earth System modelling means for EU climate policy. 👏 with @esm2025.bsky.social @optimesm-eu.bsky.social @tipesm.bsky.social #nextgems @rescueclimate.bsky.social

Another of ESM2025 strengths was the way research connected with education and policy. Not the only distinctive aspect of the project — but an important one for how results were shared and used. #ESM2025isOver

💬 One of ESM2025’s strengths was strengthening the dialogue between Earth System Models and Integrated Assessment Models — not from scratch, but in a more structured and practical way than before. What changed in practice?👇🧵 #ESM2025isOver
