There are significant limits to adaptation in the polar regions related to the rate of warming and cascading changes that are occurring, which is equivalent to double and sometimes triple the global average depending on the region . The rapid pace of change, such as sea ice loss, can outpace ecological processes and induce substantial ecological shifts  . The speed of climate change in the Arctic limits options for adaptation in communities who rely on a narrow resource base, when adaptation involves loss of culture and livelihoods, and when the costs of adaptation make it infeasible  , such as for reindeer herding  . Adapting infrastructure in response to a rapidly changing cryosphere will be limited by available technologies and the relatively higher costs associated with updating infrastructure over vast polar regions .
