N orthern Alaska is warming at a rate more than twice that of the contiguous US (Chapin et al. 2014), resulting in transformative change to the tundra and boreal ecosystems that characterize this region. A distinguishing feature of these high-latitude systems is the general absence of a uniform disturbance regime (Walker and Walker 1991). In recent years, however, this region has been marked by more frequent climatically driven disturbances. For example, the 2007 Anaktuvuk River Fire burned 1039 km 2 of tussock tundra during an abnormally warm late summer in an area with no modern record of large wildfires (Mack et al. 2011). As the climate warms, the permafrost thaws and the soil active layer (which lies above the permafrost and which freezes and thaws seasonally) deepens, thereby facilitating the decomposition and eventual release of large amounts of organic carbon (C) stored within the soil (Grosse et al. 2011). Furthermore, changes in the distribution and abundance of tundra vegetation under a warming climate may result in shifts in wildlife habitat (Callaghan et al. 2004; Martin et al. 2009), as well as changes in timing, abundance, and accessibility of resources harvested by local subsistence communities. The residents of rural communities in northern Alaska live at the forefront of this change. Consequently, both residents and land managers have highlighted the need to better understand climate impacts in the terrestrial Arctic (Figure 1), which requires scaling up from the fine resolution of most previous scientific studies to landscape-and regional-level assessments that can guide or inform resource management decisions (Martin et al. 2009). Many existing institutions are not well suited to responding to the expected effects of climate change on ecosystem services or to the uncertainties associated with these effects (Knapp and Trainor 2013; Armsworth et al. 2015), particularly in the rapidly changing Arctic. The creation of climate impacts science for decision making requires sustained communication and collab
