Adapting to the impacts of climate change on food security among Inuit in the Western Canadian Arctic
S.D. Wesche, H.M. Chan. EcoHealth (2010) 7(3):361-373. This study examined critical impacts of climate change on Inuit diet and nutritional health in four Inuit communities in the Inuvialuit Settlement Region, Western Arctic, Canada. The vulnerability of each community to changing food security is differentially influenced by a range of factors, including current harvesting trends, levels of reliance on individual species, opportunities for access to other traditional food species, and exposure to climate change hazards.
D. Garza. International Journal of Circumpolar Health (2001) 60(4):479-486. The changes in Alaska's ecosystems caused by pollution, contaminants and global climate change are negatively impacting Alaska Natives and rural residents who rely on natural resources for food, culture and community identity.
B. Sherwonit. National Parks (2004) 78(3):24-29. Spread across 32 ecoregions, Alaska's 54 million acres of national parklands are being affected by global warming in many ways, some of them obvious, others subtle. As wild landscapes change, plant communities, wildlife populations, and humans dependent on park resources must adapt or lose their niche in the ecosystem.
S.M. McNeeley, M.D. Shulski. Global Environmental Change (2011) 21(2):464-473. The well-being of rural Native communities is still highly dependent on access and ability to harvest wild foods such as salmon and moose, among many others. Over the past decade, communities in the Koyukuk–Middle Yukon (KMY) region of Interior Alaska report an inability to satisfy their needs for harvesting moose before the hunting season closes, citing warmer falls, changing precipitation and water levels, and the regulatory framework as primary causes.
Answers from the ice edge: The consequences of climate change on life in the Bering and Chukchi seas

B. Weinhold. Environmental Health Perspectives (2010) 118(2):A64-A65. There is ample evidence that the raw drive for survival—the ultimate environmental health perspective—is a common thread that often compels people to change their behavior. That is the case today for some Native Americans who are feeling the effects of dislocation and food shortages they attribute to climate change. (965 KB)
E. Engelhaupt. Environmental Health Perspectives (2009) 117(7):A292. Researchers in Canada now report the first evidence that changes in the timing of the annual sea ice breakup have contributed to a dietary shift for polar bears from western Hudson Bay in the Canadian sub-Arctic. This shift may be accelerating the bears' bioaccumulation of some classes of persistent contaminants, and people who consume these animals as part of a traditional subsistence diet could face greater exposure to contaminants that are passed up the food chain.
Center for Climate and Health Bulletin No. 4, 2010. This paper reports on a special health concern identified during surveys performed in November of 2009 and January 2010: the thawing of traditional, underground food storage cellars. Thawing permafrost is reducing the quality and quantity of food resources for some families, and resulting in cellars that have the potential to collapse and cause injury. (PDF 510.12 KB)
Center for Climate and Health Bulletin No. 1, 2009. Thawing of traditional food storage cellars due to warming soil temperature is reducing the quality and quantity of food available to residents of Point Hope.

J.D. Reist et al. Ambio (2006) 35(7):402-410. Fisheries for arctic freshwater and diadromous fish species contribute significantly to northern economies. Climate change, and to a lesser extent increased ultraviolet radiation, effects in freshwaters will have profound effects on fisheries from three perspectives: quantity of fish available, quality of fish available, and success of the fishers.
Environmental change and local foodways in the Faroe Islands, a North Atlantic artisanal whaling society
R. Fielding. Proceedings of the Fifth Northern Research Forum (2008). In the short term, the direct effects of global warming upon artisanal whaling in the Faroe Islands may be negligible. However, other environmental changes now underway, some of which share causal elements with global warming, show signs of having immediate and possibly terminal effects on this traditional cultural practice. These same environmental changes are likely to have similar effects on other artisanal and aboriginal whaling activities throughout the circumpolar North. (PDF, 347.63 KB)
PLoS Biology (2004) 2(4):doi:10.1371/journal.pbio.0020119. With recent studies suggesting that disease rates throughout the food chain have increased over the past 30 years—and are expected to increase even more, thanks to global climate change—prospects for protecting marine ecosystems depend on understanding the causes and nature of these disease outbreaks.
M. Furberg et al. Global Health Action (2011):4:DOI: 10.3402/gha.v4i0.8417. Swedish reindeer-herding Sami perceive climate change as yet another stressor in their daily struggle.

A. Stien et al. Ecology (2010)91(3):915-920. Svalbard reindeer (Rangifer tarandus plathyrynchus) have small home ranges and may therefore be vulnerable to local "locked pasture" events (ice layers limit access to plant forage) due to ground-ice formation. When pastures are "locked," Svalbard reindeer are faced with the decision of staying and live off a diminishing fat store, or trying to escape beyond the unknown spatial borders of the ice.
S. Sharma et al. Global Change Biology (2009) 15(10):2549-2562. Arctic ecosystems are especially vulnerable to global climate change as temperature and precipitation regimes are altered. An ecologically and socially highly important northern terrestrial species that may be impacted by climate change is the caribou, Rangifer tarandus.

Influences of large-scale climatic variability on reindeer population dynamics: Implications for reindeer husbandry in Norway
R.B. Weladji, Ø. Holand. The authors discuss predicted patterns of global climatic change in Norway and assess potential consequences for reindeer husbandry. They argue that, although it is clearly shown that local and global climate affect reindeer directly (e.g., increased energetic costs of moving through deep snow and in accessing forage through snow) and indirectly (e.g., effect on forage plant biomass and quality, level of insect harassment and associated parasitism), it is difficult to predict a general pattern of how future climate change will influence this species.

Mapping land cover change in a reindeer herding area of the Russian Arctic using Landsat TM and ETM+ imagery and indigenous knowledge
W.G. Rees et al. Remote Sensing of Environment (2003) 85(4):441-452. Traditionally, the tundra and the northern fringes of the boreal forest of northern Europe have been occupied by indigenous peoples whose main economic activity is reindeer herding. Groups of herders accompany their animals as they follow the annual changes in vegetation. As well as climate change, the ecology has been substantially affected by social changes that have had a marked effect on the relationship between reindeer, herder, and pasture.

J.D. Blum. Nature Geoscience (2011) 4(3):139-140. The neurotoxin methylmercury accumulates in marine biota and their predators. An analysis of seabird egg shells suggests that sea-ice cover reduces the breakdown of this highly toxic compound in sea water.
D. Carrington, guardian.co.uk, July 24, 2011. The warming of the Arctic is releasing a new wave of banned toxic chemicals that had been trapped in the ice and cold water, scientists have discovered.
ScienceDaily, January 12, 2010. The increase in temperature in the Arctic has already caused the sea-ice there to melt. According to research conducted by the University of Gothenburg, if the Arctic tundra also melts, vast amounts of organic material will be carried by the rivers straight into the Arctic Ocean, resulting in additional emissions of carbon dioxide.
Science Daily, April 27, 2011. Conversion of inorganic mercury to monomethylmercury accounts for approximately 50 per cent of this neurotoxin present in polar marine waters and could account for a significant amount of the mercury found in Arctic marine organisms.
S. Booth, D. Zeller. Environmental Health Perspectives (2005) 113(5):521-526. Under present conditions and climate change scenarios, methyl mercury has increased in the ecosystem, translating into increased human exposure over time. High and harmful levels of methyl mercury in the diet of Faroe Islanders are driven by whale meat consumption, and the increasing impact of climate change is likely to exacerbate this situation.
N. Mackin, session abstract from the 34th annual meeting of the Society for Ethnobiology, May 4, 2011. Northern Indigenous peoples worry that nutritious foods are becoming less available in their communities during these times of accelerated climate, landscape, and social change. Elders express worry about the rapidly melting glaciers and the loss of knowledge about, and access to, traditional foods that were an important part of remaining healthy.

Persistent organic pollutants in large concentrations in Arctic areas: Fires spread environmental toxins over the Arctic
ScienceDaily, June 1, 2010. Forest fires and straw and stubble burning in North America and Eastern Europe are leading to record-high concentrations of the environmental toxin PCB over Svalbard. As a result of climate change, airborne pollution is thus becoming an increasing problem in the Arctic.
Reindeer management during the colonization of Sami lands: A long-term perspective of vulnerability and adaptation strategies
I. Brännlund, P. Axelsson. Global Environmental Change (2011). Reindeer husbandry's strong connection to the land, together with the ongoing climate-change debate, has generated growing interest in its socio-ecological resilience and vulnerability. Here, using historical sources, the authors analyze the vulnerability of reindeer husbandry (and the Sami societies that depended on it) in Sweden during the 19th century, demonstrating that, although reindeer management was a much more diverse enterprise at that time than it is now, the major adaptation strategy and constraining forces were similar to those of today.
G. Kofinas et al. Polar Research (2000) 19(1):3-21. In February 1999, eighty scientists, reindeer/caribou users, and resource managers gathered in Rovaniemi, Finland, for an interdisciplinary workshop to develop a circumpolar research plan that addressed the sustainability of human/reindeer/caribou systems.
Resonance strategies of SÃ¡mi reindeer herders in northernmost Finland during climatically extreme years
T. Vuojala-Magga et al. Arctic (2011) 64(2):227-241. This study focuses on the resonance strategies of Sámi2007. "Resonance" is an instinctive and indwelling reaction of a herder to a specific change (in contrast to coping, which is a more general response). The study is based on interviews with herders, field experiences, reindeer population statistics, and weather data. (PDF, 1.37 MB)
J. Ma et al. Nature Climate Change (2011) 1:255-260. Persistent organic pollutants (POPs) are organic compounds produced by human activities that are resistant to environmental degradation. The concentrations of many POPs have decreased in Arctic air over the past few decades owing to restrictions on their production and use. As the climate warms, however, POPs deposited in sinks such as water and ice are expected to revolatilize into the atmosphere.
ESA News, April 1, 2009. Arctic reindeer herders are facing the challenges of adapting to climate change as a warmer Arctic climate makes it harder for herds to find food and navigate. To help them adapt, the ESA-backed Polar View initiative is providing the herders with satellite-based snow maps.
Sea ice and migration of the Dolphin and Union caribou herd in the Canadian Arctic: An uncertain future
K.G. Poole et al. Arctic (2010) 63(4):414-428. Caribou of the Dolphin and Union herd migrate across the sea ice between Victoria Island and the adjacent Canadian Arctic mainland twice each year, southward in fall-early winter and northward in late winter-spring. As a result of warmer temperatures, sea ice between Victoria Island and the mainland now forms 8-10 days later than it did in 1982, raising questions about the impact of delayed ice formation on the ecology of the herd.

The prevalence of <em>Toxoplasma gondii</em> in polar bears and their marine mammal prey: Evidence for a marine transmission pathway?
S.K. Jensen et al. Polar Biology (2009) 33(5):599-606. Little is known about the prevalence of the parasite Toxoplasma gondii in the arctic marine food chain of Svalbard, Norway. In this study, plasma samples were analyzed for T. gondii antibodies using a direct agglutination test. A high recent prevalence in polar bears, ringed seals, and bearded seals could be caused by an increase in the number or survivorship of oocysts being transported via the North Atlantic Current to Svalbard from southern latitudes.

When noise becomes the signal: Chemical contamination of aquatic ecosystems under a changing climate
F. Wang. Marine Pollution Bulletin (2010) 60(10):1633-1635. Evidence is now emerging that climate change alters storage, transformation, transport pathways, eco-dynamics, and bio-uptake of contaminants. Here, the authors propose a new paradigm that, during a rapidly changing climate, emission control of some contaminants may be followed by long delays, on the order of decades or longer, before ensuing reduction is seen in food-web contaminant levels.
