S2S2D Conference 2026: Advancing climate predictions from weeks to decades to benefit society

The science and practice of subseasonal to decadal prediction are at a crossroads. In recent years subseasonal and decadal prediction have matured from exploratory research areas into multi-system operational services, while multi-annual and multi-decadal timescales have emerged as further temporal realms for initialized prediction. However, inherent sources of predictability remain to be fully understood and exploited as predictions aim to address a widening array of Earth system components and to support early warnings of extreme events. Meanwhile, artificial intelligence/machine learning are propelling rapid and revolutionary developments, the outcomes of which are not yet clear.

This event will provide a forum for the current state of Earth system prediction science to be shared and discussed. It will consist of two parallel sub-conferences, respectively focusing on the subseasonal-to-seasonal and seasonal-to-decadal prediction horizons, together with plenary sessions addressing cross-cutting themes. Overall objectives include 

• Facilitating coordination and integration of global research on subseasonal to decadal Earth system prediction and its applications

• Highlighting scientific advances and emerging methodologies in subseasonal to decadal prediction 

• Sharing approaches for development of products and services from subseasonal to decadal predictions 

• Providing opportunities for Global South and early career professionals to share their work and network with the international research community.

• Informing the development of operational systems to provide Early Warnings for All (EW4A)

This meeting is open to all scientists, producers, and users involved in subseasonal to decadal climate predictions and related topics, at all stages of their careers.
