From regional to global impacts of climate change in the Arctic: an interdisciplinary perspective. The Arctic is commonly referred to as a bellwether of global climate change, as no region on the planet is experiencing more dramatic climate change. The impacts of Arctic changes are not just local, and changes can potentially trigger shifts in the global ocean and atmospheric circulations, and thus impact global climate. There is a general agreement among climate models that the changes currently observed in the Arctic will intensify in the future. Models do not agree, however, on how and at what rate the physical and biological conditions in the different Arctic regions will evolve, hampering our capacity to examine the local and global impacts of these changes. To overcome these limitations, the overarching goal of CLIMArcTIC is to understand and predict (1) regionalized responses of Arctic physical and biogeochemical conditions to future intensified climate change over the 21st century, (2) the associated impacts on the socio-economic activities in the region as well as on the global climate system. To that end, our interdisciplinary project will adopt a fully integrative approach, bringing together polar scientists specialized in physical oceanography, sea ice, climate dynamics, biogeochemistry, biology, political science, geography, law, anthropology, regional development, and geopolitics.
