Archaeological sites threatened by climate change:a regional perspective from Greenland
Archaeological sites in the Arctic are often extraordinary well-preserved due to favorable environmental conditions including cold temperatures, moist conditions and sparse vegetation, that minimize decay of the remains. However, climate change is leading to an extensive alteration of the Arctic env...

Archaeological sites in the Arctic are often extraordinary well-preserved due to favorable environmental conditions including cold temperatures, moist conditions and sparse vegetation, that minimize decay of the remains. However, climate change is leading to an extensive alteration of the Arctic environment with critical impacts on the archaeological remains: increasing air temperatures lead to permafrost thaw and increased microbial degradation in organic deposits; increased vegetation limit visibility and accessibility of sites due to plant overgrowth and plant roots disturb buried cultural layers and artefacts; finally, sea level rise and increased wave action increase coastal erosion of near-shore sites. Although the Arctic has ∼180,000 registered archaeological sites, very few have been investigated and little is known about their current state of preservation. Furthermore, a better understanding is needed of the impacts of climate change on the remains. This thesis contributes to the understanding of the spatiotemporal dynamics of environmental threats to archaeological remains in the Arctic and the influence of climate change through five interlinked studies. The first study (Paper I) is a review of the impacts of climate change on archaeological sites in the Arctic. Paper II investigates current and future microbial degradation at five contrasting archaeological sites across a climate gradient through numerical modelling of soil temperatures, water content and loss of organic carbon (OC). Paper III and IV investigate the vegetation cover at the archaeological sites and the impacts of vegetation on archaeological remains.
