Advancing Earth System Models to increase understanding of Earth system change
OpenedCode: 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).

Protecting individuals’ personal data and ensuring privacy while allowing for data processing and analysis is fundamental for our society. Privacy-preserving techniques allow to minimize the amount of personal data collected and processed, and to protect that data through advanced cryptographic methods. For instance, machine-learning methodologies are leveraged to dissect medical and behavioural data, aiming to unearth causations and insights into cyber attacks or threats. However, a substantial portion of this data comprises personal information, (such as sensitive health data), raising concerns over potential breaches or misuse, thus jeopardizing the privacy of individuals, societal well-being, and economic stability.
In addition, the challenges related to the exploitation of non-personal/industrial data assets, which could impede the full realization of the data-driven economy, are also subject to the work that can be proposed under this topic. Solutions that can provide security against quantum adversaries are also encouraged.
