This is section "h" of the Arctic chapter (chapter 5) in the BAMS State of the Climate 2022 report. 

People experience the consequences of a rapidly changing Arctic as the combined effects of physical conditions; responses of biological resources; impacts on infrastructure; decisions influencing adaptive capacities; and both environmental and international influences on economics and well-being. Living and innovating in Arctic environments over millennia, Indigenous Peoples have evolved holistic knowledge providing resilience and sustainability. Indigenous expertise is augmented by scientific abilities to reconstruct past environments and to model and predict future changes. Applying the combined understanding of Indigenous and scientific experts will be important if decision makers (from communities to governments) are to help mitigate and adapt to a rapidly changing Arctic. Considerable discussion among diverse collaborators suggests that addressing unprecedented Arctic environmental changes requires hearing one another, aligning values, and collaborating across knowledge systems, disciplines, and sectors of society. 

The Arctic sea ice has a story to tell. It is a story of change and transformation on daily, seasonal, and decadal scales. It is a story of complex interactions and feedbacks, of processes that link the ice in myriad ways with the Arctic and global systems. It is a story that has been difficult to represent with numerical models. To better understand this story has been one of the primary objectives of the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC). MOSAiC is a scientific odyssey centered on a yearlong expedition into the heart of the Arctic, to explore the story of the changing sea ice, to unravel the interdependent processes involved, and to reveal the implications of this change.
