However, adverse impacts are expected to occur both sooner and more intensely in high latitudes than in other locations (ACIA, 2005; AMAP, 2011; IPCC, 2013). Particular concerns for tundra and Arctic coastal regions include rising surface temperatures that cause near-urface (upper 3.5 metres) melting of permafrost, more frequent s r ainfall events that raise flood risks, potentially higher rates of coastal erosion, and changes to the spatial extent, thickness, and seasonality of sea ice (Engen- kaugen et al., 2008; Flannigan et al., 1998; Hanssen- auer, S B 2009; IPCC, 2012, 2013). Below the treeline, warming temperatures are expected to stimulate widespread pest outbreaks in boreal forests and to trigger further ecosystem changes in plant and animal species distributions, some of which may be non-inear in nature (Sambaraju et al., 2012; l Scheffer et al., 2012; Stralberg et al., 2015). While some of these changes may be beneficial to northern communities and settlements (for example, more rain may reduce the occurrence of forest fires), most impacts will present significant challenges to their adaptive capacity. To illustrate some of the various ways in which climate change will challenge the adaptability of northern communities, this chapter...
