Most countries in the EU develop ‘National Climate Scenario’ and related products that can be used for impact and risk assessments and the exploration of adaptation measures. Different nations have taken a range of approaches for the development of national climate scenarios, related products and the communication around the scenarios. Common challenges encountered by the providers are the communication of uncertainties, requests for very high spatial and temporal resolutions, advise on the use of climate scenarios, interactions with users, integration of climate scenarios with impact information, how to deal with new scientific insights, etc.

For this session we encourage submissions on constructing, delivering, using national climate scenarios, among others:

• Challenges in the provision of National climate information – including information gaps and the challenges in communication and providing information in ways that is relevant and accessible;
• Understanding user needs and the way users use climate scenarios, and the role of co-development of climate information and services;
• Comparisons of approaches in different countries;
• Future outlook and new opportunities in the science of scenario products drawing from novel types of information or techniques, e.g. Extreme event Attribution, decadal predictions, high resolution models, AI/ML, and new insights in the climate system and/or policy developments.
