Arctic Science Summit Week (ASSW) 2025 will be a hybrid event at the University of Colorado Boulder. The ASSW 2025 theme is “Arctic Research Planning for the Next Decade” because the week will include the Fourth International Conference on Arctic Research Planning (ICARP IV) Summit, taking place from March 25 to 28. The ICARP IV Summit will serve as a crucial milestone for shaping the Fifth International Polar Year in 2032–33.
