Storylines of Arctic Climate Change: High-resolution climate projections for the Arctic

The Polar Regions in the Earth System (PolarRES) project financed by the European Union’s Horizon 2020 research and innovation programme involved more than 80 researchers from 21 organisations across Europe, Asia, and North America. The project, which began in September 2020 produced an ensemble of high-resolution regional climate simulations for the Arctic and Antarctic in support of impact assessments in the polar regions. These simulations from the PolarRES project used a novel storylines approach and a multi-disciplinary framework to develop century-long climate projections at spatial scales of approximately 12km which is unprecedentedly high resolution for any multi-model ensemble covering the Arctic for such a long period of time. The PolarRES ensemble followed the CORDEX protocol and are publicly available for the wider scientific community. In this talk, I will present an overview of the PolarRES simulations, their performance, and show some recent applications of these climate simulations for studying the impacts of future climate change in the Arctic.
