Annual meeting of international impact modelers discusses adaptation

From April 22-26 2024, PIK hosted the annual international workshop of the Intersectoral Impact Model Intercomparison Project (ISIMIP). This initiative brings together researchers from diverse fields of climate impacts, e.g. water, agriculture, fisheries, health and forestry, with the goal to provide harmonized information on climate impacts for joint assessment and for use in economic modeling. The workshop focused on three main topics. Firstly, a wealth of results was presented on attributing observed impacts to anthropogenic climate change. A second focus was on projecting impacts of climate change for different warming and socioeconomic futures, with a focus on key-risks for societies such as health impacts. Thirdly, in joint discussion with representatives from the climate and integrated assessment modeling communities plans and demands for the next assessment report of the Intergovernmental Panel on Climate Change (IPCC AR7), which will also coincide with the next round of the Global Stock Take to take place in 2028. Working Group 2 co-chair Bart van den Hurk pointed out that both adaptation research and stakeholder-oriented research on implementation will play a crucial role in this. Fittingly, the imminent release of input data for the next round of ISIMIP impact modeling (ISIMIP3b) was announced at the workshop. These results will distinguish impacts with and without adaptation and can inform ACCREU work directly, as several ACCREU team members are actively involved in the ISIMIP work, for example in the energy, land use and extreme events modeling. Therefore, ACCREU is in a great position to take up the challenge and provide influential research for the upcoming policy processes in the 7th Assessment Report and the 2nd Global Stock Take.
