Climate impact diagrams aim to build a shared understanding among all stakeholders on the opportunities and risks of climate change for the different sectors. It is a first step to start the conversation about climate change adaptation and work towards a joint approach for taking climate measures, identifying co-benefits and offering ideas for action. Impact diagrams present a simplified, visual summary of current scientific knowledge of climate effects and climate consequences. The diagrams help to gain more insight into opportunities and risks and can kickstart the search for additional knowledge or collaboration partners.
