Highly resolved projections of climate and vegetation indicate major changes in northern Scandinavia
Through Arctic amplification, global climate change is projected to disproportionally affect high-latitude environments. Additionally, the geographical heterogeneity and complex terrain of mountains promote climate-driven ecological change on fine spatial scales. We used a high-resolution convection-permitting regional climate model (HCLIM) and a state-of-the-art dynamic vegetation model (LPJ-GUESS) to explore mid-twentieth century implications o…
Resource Extraction and Arctic Communities
For decades, a post-Cold War narrative heralded a 'new Arctic', with melting ice and snow and accessible resources that would build sustainable communities. Today, large parts of the Arctic are still trapped in the path dependencies of past resource extraction. At the same time, the impetus for green transitions and a 'new industrialism' spell opportunities to shift the development model and build new futures for Arctic residents and Indigenous p…
Impacts of climate warming on reindeer herding require new land-use strategies
Climate in the Arctic has warmed at a more rapid pace than the global average over the past few decades leading to weather, snow, and ice situations previously unencountered. Reindeer herding is one of the primary livelihoods for Indigenous peoples throughout the Arctic. To understand how the new climate state forces societal adaptation, including new management strategies and needs for preserved, interconnected, undisturbed grazing areas, we cou…
Reindeer husbandry in peril?—How extractive industries exert multiple pressures on an Arctic pastoral ecosystem
Environmental changes and their consequences on biodiversity are known to have far‐reaching effects on the resilience of animal populations and associated livelihoods around the world. To counteract negative demographic and economic effects on pastoralism, knowledge about the historical and current status of the environment is essential. In this study, we show how extractive industries, especially large‐scale mining, induced a cascade of land con…
Social-ecological-technological systems consequences of mining
Understanding the impacts of extractive industries on sustainable development requires analyzing them as part of dynamic social-ecological-technological systems. Building on insights from studies of social-ecological systems and socio-technical systems, as well as fieldwork on the impacts of mining in the Nordic Arctic, this article presents an analytical framework for co-production of knowledge about the role of industrial or infrastructure proj…
Deglaciation of Fennoscandia
To provide a new reconstruction of the deglaciation of the Fennoscandian Ice Sheet, in the form of calendar-year time-slices, which are particularly useful for ice sheet modelling, we have compiled and synthesized published geomorphological data for eskers, ice-marginal formations, lineations, marginal meltwater channels, striae, ice-dammed lakes, and geochronological data from radiocarbon, varve, optically-stimulated luminescence, and cosmogenic…
Changing Arctic snow cover
Snow is a critically important and rapidly changing feature of the Arctic. However, snow-cover and snowpack conditions change through time pose challenges for measuring and prediction of snow. Plausible scenarios of how Arctic snow cover will respond to changing Arctic climate are important for impact assessments and adaptation strategies. Although much progress has been made in understanding and predicting snow-cover changes and their multiple c…
Late-Holocene temperature and precipitation changes in Vindelfjällen, mid-western Swedish Lapland, inferred from chironomid and geochemical data
In this article, we present results from a palaeolimnological study from Lake Vuoksjávrátje in the mountain tundra region in the Vindelfjällen Mountains, northwest Sweden. We suggest that the influence of precipitation may be one of the factors causing discrepancies between chironomid-based late-Holocene July temperature (JulyT) reconstructions from Fennoscandia. We combine quantitative temperature reconstruction using chironomids for the last 51…
Climate Change, Moose and Humans in Northern Sweden 4000 cal. yr BP
Major cultural and environmental changes took place in the interior of Northern Sweden, beginning about c. 4200 cal. yr BP (or 2200 cal. BC). We present a causal, plausible, relationship linking climate change, a key resource and human culture. Moose (Alces alces) disappeared relatively fast from the human culture evidenced by a rapid decrease in usage and symbolism. Given the climatic data reconstructed at hand, a drastic change towards colder a…
Influence of geomorphological setting, fluvial-, glaciofluvial- and mass-movement processes on sedimentation in alpine lakes
Lacustrine sediments are often used for paleoclimate reconstructions as continuous archives of several physical and biological proxies. The relation between autochthonous and allochthonous sedimentation in alpine lakes is a complex system that may cause difficulties when interpreting biological and physical parameters. Results from previous studies of alpine lakes in northern Sweden have demonstrated that non-glacial processes produce minerogenic…
North Atlantic region atmospheric circulation dynamics inferred from a late-Holocene lacustrine carbonate isotope record, northern Swedish Lapland
The first high-resolution record of climate variation based on the oxygen and carbon isotope composition of authigenic carbonate for northern Scandinavia is presented. Modern lake-water isotope data indicate that controls on its oxygen and hydrogen (δ 18 O w and δD w ) composition are unlikely to be evaporation or temperature, and its variations must therefore reflect changes in, or at the source of, precipitation. Substantial and persistent chan…
Holocene climate variability
Although the dramatic climate disruptions of the last glacial period have received considerable attention, relatively little has been directed toward climate variability in the Holocene (11,500 cal yr B.P. to the present). Examination of ?50 globally distributed paleoclimate records reveals as many as six periods of significant rapid climate change during the time periods 9000"8000, 6000"5000, 4200"3800, 3500"2500, 1200"1000, and 600"150 cal yr B…
Radiocarbon Reservoir Ages from Freshwater Lakes, South Georgia, Sub-Antarctic
Lake sediments have the potential to preserve proxy records of past climate change. Organic material suitable for radiocarbon dating often provides age control of such proxy records. Six shallow freshwater lakes on the sub-Antarctic island of South Georgia were investigated for carbon reservoir effects that may influence age-depth profiles from lake sediment records in this important region. Paired samples of particulate organic matter (POM) from…
Millennial-scale climate changes on South Georgia, Southern Ocean
The location of South Georgia (54°S, 36°W) makes it a suitable site for the study of the climatic connections between temperate and polar environments in the Southern Hemisphere. Because the mass balance of the small cirque glaciers on South Georgia primarily responds to changes in summer temperature they can provide records of changes in the South Atlantic Ocean and atmospheric circulation. We use grey scale density, weight-loss-on-ignition, and…
Holocene climatic change in Swedish Lapland inferred from an oxygen-isotope record of lacustrine biogenic silica
Holocene climatic variability was studied in a 9500-year lake-sediment sequence from the Abisko region in Swedish Lapland, using the oxygen-isotope ratio in diatom biogenic silica (d 18 O si ). Oxygen-and hydrogen-isotope ratios of waters from the Abisko area suggest that in this region the evaporative flux is small and the isotopic composition of most lakes reflects that of the local precipitation. The hydrological setting of the region and sens…
Late-Holocene glacier variations in the Cordillera Darwin, Tierra del Fuego, Chile
Radiocarbon dates obtained on peat and macrofossils, sampled both proximally and distally, of a terminal moraine in the Bahia Pia area, Cordillera Darwin, Tierra del Fuego, Chile, indicate that the glacier system reached maxima sometime before 3060 BP, prior to 940 BP and between 940 BP and 675 BP. The glacier retreated 4 km to a pinning-point position where it dammed a lake before 2605 ± 80 BP, between 1950 ± 75 and 1790 ± 75 BP and some time sh…
Proglacial lacustrine sediments from El Altar, Ecuador
Late-Holocene glacier variations on El Altar, Ecuador, have been reconstructed from proglacial lacustrine sediments. Variations in bulk density and organic content in sediment cores from Laguna Verde, are interpreted as representing a record of the Neoglacial activity of the Obsipo Glacier. Two sedimentological units of laminated silt and clay represent two late-Holocene episodes of glacier expansion, which probably occurred during the last mille…
