ClimXtreme is a research programme funded by the German Federal Ministry of Research, Technology and Space (BMFTR) that comprises 25 individual projects and aims to improve understanding of European extreme weather events and associated uncertainties under anthropogenic climate change.
As part of the cross‑project collaboration, a coordinated approach is being established to initiate and sustain targeted stakeholder communication and support it throughout the project period. The aim is to develop information, data and tools targeted to stakeholder needs. To this end, Hazard‑specific Stakeholder Interaction (HaSSi) groups coordinate collaborative work on windstorms, heavy precipitation, and heat/drought. This contribution summarizes activities within the HaSSi Heat/Drought group and provides an overview of the activities and outcomes within the project.
Our group brings together diverse projects that study heatwaves and droughts from multiple perspectives. These include their underlying large‑scale dynamics, their impacts (for example on crops and fire weather), and event‑based attribution methods. The combination of expertise from various fields gives us a multifaceted perspective on heat and drought events, which we use in two ways:
Communication with stakeholders is maintained through monthly online seminars, in which scientific findings and their relevance to stakeholders are discussed, thereby gathering valuable input from the stakeholders' perspectives. As valuable, cross-project output tailored to stakeholders, we also analyse current extreme events from the multifaceted view gained from the respective individual projects. We illustrate this approach using findings from the ClimXtreme report on the European Summer 2025.
