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!

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

🌍 Earth System Insights: from our Horizon Projects Briefing 6 European Horizon projects gathered their insights together for an in-depth forum with the European Commission (DG RTD & DG CLIMA). Here’s what they had to say 👇 🔗 bit.ly/4pgvktX #ClimateAction #EarthSystem #HorizonEU

💬 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

Today, ESM2025 officially comes to an end! Since 2021, our European consortium has been building a new generation of Earth System Models to support mitigation & adaptation strategies aligned with the Paris Agreement. Watch these clips of our final video to see how far we've come! 🧵👇 #ESM2025isOver

In many ways, this work only begins to scratch the surface of what is needed to robustly evaluate land-based CDR.... ... and to end this #ESM2025research series of posts on our latest research highlight about land-based carbon dioxide removal, what's ahead? 🧵👇

Our analysis suggests that uncertainties in current carbon stocks are even larger than those related to how these stocks may respond to future climate change... Want to know more? 👀Check out our latest research highlight on land-based carbon dioxide removal: bit.ly/4qMYPEy #ESM2025research

The biggest wild card for land-based mitigation might not be future response of carbon stocks to climate change — but today’s carbon stock densities. Small shifts within their plausible range flip land-use emissions from slightly net-negative to +60 GtCO₂ by 2050. #ESM2025research

In the process of exploring ways to integrate carbon stock dynamics into the ESM-IAM modelling framework... 💡...a case of scientific serendipity emerged, giving rise to an entirely new line of research that had not been previously explored! 🧵👇(1/7) #ESM2025research

What our multimodel analysis has shown: 🌴In tropical regions, planting trees tends to cool the climate; ❄️In high-latitude areas, new forests can darken snowy surfaces & cause local warming, despite their CO₂ removal potential Tree planting isn’t a simple, one-size-fits-all fix overall! (1/4)🧵👇

Excellent summary of the work I contributed to in @esm2025.bsky.social, an EU-funded project that ends this year. Here are my key take-aways in a 🧵 , but I recommend reading this Research Highlight if you want to know more! Several papers are in preparation from this work, so stay tuned.

Can we really count on land to deliver climate mitigation? Our new highlight unpacks what AR/BECCS can do — and where uncertainties bite (carbon stocks, permanence, local climate effects). Full story → bit.ly/4qMYPEy #CDR #ESM2025research @euclimateaction.bsky.social

Stories abound these days showing that global warming exceeding 1.5C is now part of science's best estimate. What does that mean for the #ParisAgreement 1.5C goal? A good time to revive a thread about a piece we wrote earlier this year on this topic in @science.org 👇🌍🌡️
