From 7 to 10 April 2025, climate scientists, Earth system modellers, impact researchers, and science communicators will gather in Paris for a week dedicated to advancing our understanding of climate tipping points. The programme includes the TipESM & ClimTip Joint Conference, the TipESM Annual Meeting, and a dedicated Joint Project Meeting.

7–8 April 2025 | TipESM & ClimTip Joint Conference

On April 7 and 8, the TipESM & ClimTip Joint Conference will take place at the Henri Poincaré Institute at Sorbonne University. Organised by the two Horizon Europe projects, the event will bring together experts working at the forefront of tipping point research and serve as a platform for clustering Horizon Europe initiatives.

Throughout the two-day event, the conference will:

• Share knowledge across the clustered projects to strengthen impact and research in tipping point initiatives
• Present the latest progress and findings across five critical themes: Cryosphere, Biosphere, AMOC & SPG, Tipping point prediction methodologies, and Impacts and communication
• Empower and initiate interdisciplinary collaboration, connecting researchers across different expertise and projects
• Improve communication by translating complex science into impactful insights for the public, media, and policymakers

9–10 April 2025 | TipESM Annual Meeting

From April 9 to 10, TipESM will hold its Annual Project Meeting. This internal meeting will explore the progress made across the project’s six scientific themes and set the course for upcoming research from the project.

The six themes are:

1. Simulating tipping points in the Earth system with an ensemble of ESMs and dedicated experiments
2. Delivering new knowledge on climate tipping points and their driving processes
3. Developing early warning indicators and assessing the risk for cascades of tipping points across the Earth system
4. Identifying climate-driven tipping points in ecosystems and society
5. Assessing the impacts of tipping points on ecosystems and society
6. Constraining future tipping point risks and providing safe mitigation emission pathways

Key breakout group discussions will focus on:

• Detection methods for tipping points across social-ecological systems
• Experimental design: forced, ensemble, and domain-specific approaches
• Early warning indicators register
• TipESM risk register

10 April 2025 (Afternoon) | TipESM & ClimTip Joint Project Meeting

On the afternoon of April 10, the TipESM and ClimTip teams will reconvene for a Joint Project Meeting to build on the outcomes of the Joint Conference earlier in the week. The joint meeting will sum up the insights and discussions from the conference themes and take these insights further through breakout groups. As a common thread throughout both projects, the joint project meeting will include a dedicated session on storylines, focusing on how to integrate scientific findings into compelling, policy-relevant narratives that can connect science, risk, and communication.
