  • Advancing Earth System Models to increase understanding of Earth system change

    Opened

    Code: 37247 | Identifier Code: HORIZON-CL5-2025-06-D1-02 | Programme name: 2939 | Sub-program: Climate, Energy and Mobility (Cluster 5)(2021-2027) | Start submission calls: 06/05/2025 | End submission calls: 24/09/2025

    ESMs are the main tools used to assess future changes in the climate system.

    Their resolution and realism have increased over the last two decades. Despite these advances, there are still several poorly understood and simulated processes, interactions and feedbacks that limit their ability to provide accurate predictions and forecasts of global and regional Earth system change, and to help understand and quantify future climate variability.

    A particular challenge is how variability interacts with extreme events (including complex ones), particularly in relation to rainfall and water availability (both excess and scarcity).

  • Climate simulations data and knowledge for optimal support of IPCC Assessments and International Policy

    Opened

    Code: 37244 | Identifier Code: HORIZON-CL5-2025-06-D1-01 | Programme name: 2939 | Sub-program: Climate, Energy and Mobility (Cluster 5)(2021-2027) | Start submission calls: 06/05/2025 | End submission calls: 24/09/2025

    Given the rapidly evolving climate crisis, there is an increasing need for accurate, reliable and usable information at global and local scales, as well as in the short and long term.

    This information supports a range of requirements, including those related to policies. In particular, the simulations and knowledge provided to the IPCC, including the Seventh Assessment Report (AR7) and subsequent reports, need to be internally consistent and well coordinated.

    The modelling, setting, set and design of simulations should be appropriate to meet societal and policy requirements in order to support the most timely developments in European and international climate policy.

    For these levels, it is important to ensure the right level of driver alertness in relation to the environment and the level of automation in order to avoid dangerous situations due to cognitive distraction.

  • Integration of Post-Quantum Cryptography (PQC) algorithms into high-level protocols

    Opened

    Code: 37224 | Identifier Code: HORIZON-CL3-2025-02-CS-ECCC-06 | Programme name: 2939 | Sub-program: Civil security for society (Cluster 3) (2021-2027) | Start submission calls: 12/06/2025 | End submission calls: 12/11/2025

    The transition to post-quantum cryptography requires changing the uses of most currently deployed public-key cryptography (RSA and ECC). Research and development efforts are providing signature systems and key-exchange mechanisms that are generally accepted to withstand attacks using classical and quantum computers. Efforts are on the way to include these in core Internet protocols such as Transport Layer Security (TLS). While this is an important development, many more protocols need to be modified to be quantum-ready and to ensure backward compatibility with legacy systems.
