Keynotes

We are really happy to announce the first two keynote speakers of this year's workshop:

Wednesday:

  • Jeroen Aerts will give some insights around adaptation in water-related sectors and beyond

Thursday:

  • Paula Harrison will present nexus inter-linkages among biodiversity, water, food and health
  • Damaris Zurell will talk about Biodiversity as a cross-cutting topic integrating e.g. coastal ecosystems, water quality, land use.

Scope

The workshop, while serving as the main annual ISIMIP workshop, will be an activity as part of the Horizon Europe project OptimESM, and an excellent opportunity to connect the climate and climate impact modelling activities with regard to potential inputs to the IPCC Seventh Assessment Report (AR7). In line with that, there will be dedicated discussion sessions integrating the ESM, IAM and ISIMIP communities:

  • to identify options to define an “ISIMIP4 Fast Track” simulation round dedicated to provide climate impact model simulations based on the latest generation of ESM simulations in time for IPCC AR7,
  • to discuss data needs with regard to variables, bias-adjustment, and downscaling ,
  • to identify challenges in representing overshoot dynamics as a prominent characteristic of the OptimESM and CMIP7-ScenarioMIP scenarios both from the climate as well as the climate impact modellers perspective,
  • to discuss and prepare decisions on specific scenarios to focus on for the AR7.

Additionally, ISIMIP3 simulation results will be presented both in context of impact model evaluation and impact attribution (ISIMIP3a), as well as future projections of risks (ISIMIP3b) with a focus on what we still have to learn regarding the preparation and application of the newly provided direct human forcings. 

There will be slots for presentations, break-out groups, discussion rounds, etc. within the various sessions, and you are welcome to submit contributions to the topics mentioned above in the registration mask. Moreover, there will be dedicated sectoral meetings, a poster session, and networking activities, as well. 

Stay tuned for announcements on exciting keynotes and please stay updated for a tentative agenda and updates to come.
