Environmental changes are creating new hazards in the Arctic, and shifting how we understand and plan for challenges from disasters to military strategies. Traditional methods for assessing risks will often underestimate impacts, particularly when geophysical and ecological changes undermine resilience and adaptability, and when external shocks like COVID-19 stress existing systems. This webinar with co-PI Dr. Chad Briggs explores tools for developing risk scenarios in the Arctic, and illustrates initial results of security simulations of disaster response in Alaska during the current pandemic.
