Igloo

An igloo is a dome-shaped temporary shelter constructed from blocks of compacted snow by the Inuit people of the Arctic regions, including northern Canada, Alaska, and Greenland, serving primarily as a winter hunting or travel refuge rather than a permanent home.^[1]^[2]^[3] Traditional igloo construction involves selecting a site with firm, wind-packed snow, then cutting rectangular blocks using a snow knife made of bone, stone, or metal. These blocks are arranged in a spiral pattern, with each successive layer angled inward to form a stable catenoid dome, culminating in a keystone block at the top; the entire process can be completed by an experienced builder in about an hour.^[2]^[3] A low entrance tunnel, often lined with snow or sealed with animal skins, prevents wind entry while allowing cold air to sink and pool at the bottom, as warm air rises to the sleeping platform; a small ventilation hole at the apex releases built-up gases.^[1]^[2] The interior is typically lined with furs or skins for additional insulation, and a soapstone lamp fueled by seal oil provides light, heat, and cooking capability.^[1]^[3] The engineering of the igloo leverages snow's properties as an effective insulator—due to its 95% air content trapping heat—while the dome structure distributes weight evenly, allowing the walls to support significant loads, such as a person's weight on the roof.^[2]^[3] Inside temperatures can reach 0–10°C (32–50°F) even when external conditions drop to -40°C (-40°F), achieved through body heat retention, minimal air exchange, and the refreezing of interior meltwater into a stronger ice layer.^[2]^[3] Historically used for thousands of years by Inuit groups during seasonal migrations or hunts, igloos accommodated one to several families and were dismantled after use, with permanent villages relying on sod or skin tents in other seasons.^[1]^[3] In contemporary times, traditional igloo building has declined due to climate change reducing suitable snowpack and the adoption of modern housing, though as of 2025 it remains a cultural practice taught for heritage preservation in Inuit communities, such as through workshops in Nunavut, and for occasional emergency use.^[1]^[4] The igloo's design has also inspired modern engineering, demonstrating principles of sustainable, low-impact architecture in extreme environments.^[2]

Overview and Terminology

Definition and Purpose

An igloo is a dome-shaped structure constructed from blocks of compacted snow, traditionally serving as a temporary winter shelter for Inuit people in the Arctic.^[5]^[6] Its primary purposes include providing protection from fierce winds, extreme cold, and wildlife, while functioning as hunting camps, short-term family dwellings, or communal gathering spaces during travel or emergencies.^[5]^[6] This shelter is particularly associated with the Central Arctic Canadian Inuit, such as the Iglulingmuit, and the Inuit of Greenland's Qaanaaq region, who used it for short-term stays on hunting expeditions.^[5]^[7] Due to the insulating properties of snow and the retention of body heat from occupants, igloos can maintain internal temperatures between -7°C and 16°C even when external conditions reach -45°C.^[6]^[5]

Etymology and Naming

The term "igloo" originates from the Inuktitut word iglu (ᐃᒡᓗ), which broadly means "house" and applies to any form of dwelling, including those constructed from snow, sod, stone, or other materials.^[8] The plural form in Inuktitut is igluit (ᐃᒡᓗᐃᑦ), reflecting its use for multiple structures.^[9] Within Inuit languages, more specific terminology distinguishes types of houses; for instance, igluvijaq refers explicitly to a snow house, highlighting the adaptability of the root word to particular building methods. Regional variations in naming appear in place names and dialects, such as Igloolik in Nunavut, which derives from iglu and translates to "place of houses" or "there are houses," originally alluding to clusters of sod or other dwellings rather than snow structures alone.^[10] This illustrates how the term's linguistic roots extend beyond winter shelters to denote settled habitation sites in Inuit toponymy. The word entered English usage in the early 19th century, first recorded in 1824 through accounts by Arctic explorers who encountered Inuit dwellings, initially denoting dome-shaped snow huts but soon broadening in application.^[8] In contemporary English, "igloo" is often misused to describe any improvised snow shelter, diverging from its original comprehensive meaning as a general term for a home.^[11] Not all Inuit groups traditionally constructed snow houses, and terminology differs across related dialects; for example, in Alutiiq (a Yupik language), the equivalent for "house" is ungluq, though snow dome structures were not commonly used by Yupik peoples.^[12]

Historical and Cultural Context

Origins in Inuit Society

The igloo, known in Inuktitut as iglu meaning "house," was used occasionally by the Thule people, direct ancestors of modern Inuit, who developed sophisticated Arctic survival technologies around 1000 CE in the western Arctic near Alaska before migrating eastward around 1200 CE; igloo construction later became a key adaptation among their Inuit descendants.^[13] This nomadic lifestyle, centered on hunting marine mammals like seals and whales, necessitated portable winter shelters in regions with abundant snow, leading to the occasional use of snow houses by early Inuit between 1200 and 1500 CE.^[13] Archaeological evidence for these structures is minimal, as they melted with seasonal thaws, but ethnographic records confirm their role in enabling mobility across the harsh Central Arctic environment.^[5] Over centuries, igloo design evolved from rudimentary snow enclosures—likely simple pits or drifts augmented for wind protection—to refined dome-shaped forms optimized for thermal efficiency and structural integrity.^[5] This progression was shaped by Thule migration patterns, which spread innovations eastward into varying climates, and by the need for quick assembly during extended hunting trips in snow-dominated landscapes.^[13] Regional variations emerged, such as clustered igloos among Iglulingmuit groups or flat-topped entrances among Inuinnait, reflecting local environmental influences on construction techniques.^[5] Igloos were primarily employed by Inuit communities in Canada's Central Arctic (from the Mackenzie River delta to Hudson Bay) and the Qaanaaq region of Greenland, where frequent cold snaps produced dense, block-forming snow ideal for building.^[5] In contrast, Alaskan and Siberian Inuit groups rarely used them, favoring semi-subterranean sod houses or skin tents instead, due to the prevalence of dry, powdery snow unsuitable for stable blocks in those coastal areas.^[5]^[14] European contact in the mid-19th century documented and popularized igloos beyond Inuit society, notably through explorer John Rae's expeditions for the Hudson's Bay Company. During his 1846–1847 journey and subsequent 1850s travels in the Boothia Peninsula, Rae learned igloo construction from Inuit guides, preferring their superior insulation over European tents for winter survival.^[15] His detailed reports to the British Admiralty highlighted the igloo's practicality, contributing to broader Western recognition of Inuit ingenuity amid ongoing searches for the lost Franklin Expedition.^[15]

Traditional Lifestyle Integration

Igloos played a central role in the semi-nomadic hunter-gatherer lifestyle of traditional Inuit societies, serving as essential winter shelters constructed seasonally to support hunting expeditions, family living, and communal ceremonies. These dome-shaped structures enabled small family groups to pursue vital resources such as seals and caribou across the vast Arctic landscape, providing portable and efficient housing that aligned with the demands of a mobile existence. In contrast to the summer skin tents known as tupiq, igloos facilitated survival during the long, harsh winters, allowing Inuit communities to maintain year-round mobility without permanent fixed dwellings.^[16] Socially, igloo construction and use reinforced community bonds and gender-specific roles within Inuit families and groups. Men typically handled the communal building process, cutting and stacking snow blocks to create the shelter, which often involved cooperation among family members or neighboring hunters to complete the task efficiently during travels. Women, meanwhile, managed the interiors by lining platforms with furs for bedding and warmth, tending to oil lamps for light and cooking, and organizing daily domestic activities. This division symbolized broader Inuit values of ingenuity and collective resilience, as the igloo became a shared space for social interactions, such as visiting between families or hosting gatherings in larger structures.^[16]^[17] Culturally, igloos held profound significance in Inuit oral traditions, art, and spirituality, often representing the home as a metaphor for protection, adaptability, and endurance against environmental challenges. Stories and songs performed inside igloos, including song duels to resolve disputes, were passed down through generations, embedding the structure in narratives of survival and harmony with the land. In artistic expressions and spiritual practices, the igloo embodied communal ingenuity and the transmission of knowledge, with elders teaching construction techniques as part of holistic cultural education.^[16]^[17]^[18] The igloo's integration into traditional life declined significantly after the 1950s, as Canadian government policies relocated Inuit to permanent settlements for access to schools, healthcare, and wage economies, disrupting semi-nomadic patterns and reducing the need for seasonal snow dwellings.^[16]

Design and Construction

Materials and Preparation

The construction of a traditional igloo begins with careful site selection to ensure stability and accessibility of suitable snow. Inuit builders choose flat, stable areas sheltered from strong winds, where the snowpack is deep—typically at least one meter—and dry to avoid loose powder that crumbles during cutting.^[19]^[20] Such locations provide a solid foundation of firm, wind-packed snow, known as pukaangajuq in Inuktitut, which is essential for structural integrity.^[19]^[21] The primary material for igloo blocks is wind-packed snow, a form of compacted firn that has been hardened by wind but remains soft enough to carve without fracturing. This snow type is preferred for its density and minimal layering, which prevents blocks from breaking apart.^[19]^[20] Builders test the snow's firmness by probing with a long metal rod called a huvgut to confirm depth and solidity before proceeding.^[21] The snow's structure, filled with air pockets between ice crystals, provides excellent thermal insulation by trapping heat and reducing conduction.^[19]^[1] Preparation involves cutting the snow into uniform blocks using specialized tools. Traditionally, the pana—a snow knife made from ivory, bone, or whale bone—is used to slice the snow into rectangular or four- to six-sided bricks.^[19]^[21]^[1] In contemporary adaptations, metal saws or handsaws serve as alternatives for precision cutting.^[20] Blocks are typically sized 60 to 90 centimeters long, 30 to 50 centimeters high, and 15 to 25 centimeters thick, weighing approximately 10 to 30 kilograms each to allow easy handling while maintaining strength.^[20]^[22] Water may be sprinkled on edges to bond blocks as they freeze together.^[20]

Step-by-Step Building Techniques

The construction of a traditional Inuit igloo begins with selecting a suitable site on firm, wind-packed snow and marking a circular foundation approximately 2-4 meters in diameter. A trench is then cut around this perimeter to a depth of about 15-20 cm, from which the first layer of snow blocks is harvested using a specialized snow knife or saw; this trench also serves as the base for the structure, ensuring stability on the uneven tundra surface.^[23]^[1] Blocks, typically 60-90 centimeters long, 30-50 cm high, and 15-25 cm thick, are cut from the compacted snow within the marked area and stacked in a continuous spiral pattern, with each subsequent row leaning gradually inward at an initial angle of about 15 degrees. This spiral technique reduces the number of blocks per row as the structure rises, naturally forming a catenary arch that distributes weight evenly and culminates in a low dome 1.5-3 meters high; roughly 50-100 blocks are used in total, depending on the intended size.^[24]^[25]^[20] Once the dome is nearly complete, a small window is inserted near the top using a block of clear ice or translucent snow for natural light and ventilation, while the entrance is extended into a low tunnel 1-2 meters long, dug slightly below floor level to act as a cold trap that prevents warm air from escaping and cold winds from entering directly. The tunnel is often fitted with a skin curtain for added insulation.^[1]^[23] Finally, the interior is smoothed by applying gentle heat from body warmth or a qulliq (traditional seal-oil lamp), which causes a thin layer of surface snow to melt and refreeze into a hard, glossy ice lining for better insulation and durability; exterior surfaces are then reinforced by packing additional snow into crevices and mounding it over the dome to consolidate the structure. An experienced builder can complete this process in 1-3 hours working alone.^[23]^[24]

Variations and Types

Small and Temporary Igloos

Small and temporary igloos represent the most basic form of Inuit snow dwellings, tailored for rapid assembly and individual or duo occupancy during short excursions. These structures typically feature a diameter of 1 to 2 meters and a comparable height, forming a single-room dome that accommodates just 1 to 2 people in a confined space.^[1]^[26] Experienced builders can erect such an igloo in approximately 30 to 60 minutes by cutting and stacking blocks of compacted snow in a low spiral, starting with a circular base and gradually reducing the circle's diameter to create the arching walls.^[26] The primary function of these igloos is to provide essential overnight protection for hunters or travelers in the Arctic winter, shielding occupants from biting winds, blizzards, and subzero temperatures during seal hunts or migrations. Unlike more elaborate designs, they incorporate minimal features, such as a low tunnel entrance, to facilitate quick access while conserving heat.^[1]^[26] Internally, the space is austere, offering barely enough room for a sleeping platform of packed snow covered with furs, a body-length sleeping bag, and a small stone or oil lamp for minimal illumination and warmth.^[1]

Large and Communal Igloos

Large and communal igloos, known in Inuktitut as qaggiq or qalgiq, represent scaled-up adaptations of traditional snow dwellings designed to accommodate multiple families or community members during extended winter periods. These structures typically feature diameters ranging from 4 to 8 meters, with heights up to 4.6 meters, allowing them to house 5 to 20 people for days or even weeks. Construction often involves multiple interconnected domes, up to five rooms linked by low tunnels to minimize heat loss and facilitate movement, incorporating raised sleeping platforms lined with furs and dedicated storage areas for tools and provisions.^[27]^[28] The primary purposes of these igloos extended beyond basic shelter to serve as vital social and ceremonial hubs in Inuit society, functioning as family winter homes or expansive feast halls for gatherings. As family residences, they provided insulated spaces for daily living, including cooking via kudlik oil lamps and communal sleeping arrangements that promoted warmth through shared body heat. In communal contexts, qaggiq hosted significant events such as midwinter festivals like the Tivajuut, where communities engaged in feasting, drum dancing, storytelling, and shamanistic rituals to strengthen social bonds and mark seasonal transitions. These gatherings emphasized cultural transmission and conflict resolution, underscoring the igloo's role in fostering community cohesion.^[29]^[28] Variations in large igloos included semi-permanent designs with reinforced walls using additional snow layers or stone foundations for stability, particularly in areas with suitable snow conditions. These were often built collaboratively by teams of 4 to 12 individuals over several days, requiring 70 to over 100 snow blocks depending on size, to prepare for events like spring celebrations or seasonal hunts. Historical accounts describe multi-room configurations, such as those documented in early 20th-century ethnographic studies, where four kudlik lamps illuminated interconnected chambers for diverse activities. One notable example from 19th-century observations in the Central Arctic featured a 3.1-meter diameter igloo sheltering 17 travelers in an emergency situation, highlighting the adaptability of these structures for group mobility.^[27]

Scientific Principles

Thermal Insulation Mechanics

The thermal insulation of an igloo primarily relies on the physical properties of snow, which consists of ice crystals trapping approximately 90-95% air by volume in fresh, loosely packed forms. These air pockets significantly reduce heat conduction through the structure, as air is a poor conductor of heat compared to solid materials. The effective thermal conductivity of such snow ranges from 0.05 to 0.6 W/m·K, depending on density, which is substantially lower than that of ice (about 2.2 W/m·K) and limits the rate of heat loss from the interior to the exterior. This property imparts an R-value of roughly 1 to 2 per inch of snow thickness, providing effective insulation even in walls typically 1-2 feet thick.^[30]^[31]^[32] The hemispherical dome shape of the igloo further enhances insulation by minimizing the surface area-to-volume ratio, thereby reducing the pathways for heat escape relative to the enclosed space. This geometric efficiency ensures that internal heat is retained more effectively than in rectangular or other forms, concentrating warmth within a smaller exposed area while distributing any load evenly. In extreme Arctic conditions, where external temperatures can drop to -45°C or lower, this design allows the interior to stabilize at -7°C to 16°C when heated solely by human occupants.^[33] Primary heat sources inside an igloo include human body heat and traditional oil lamps fueled by animal fat, such as seal blubber. The metabolic heat output of 4-5 occupants, each generating approximately 100 W, can raise the internal temperature by 20-30°C above ambient conditions through convection and radiation, warming the air and surfaces without excessive melting due to the snow's insulating barrier. Oil lamps contribute additional radiant heat—typically 50-200 W per lamp—while their low flame temperature and the igloo's ventilation prevent widespread wall melting, as the generated warmth primarily circulates internally via natural convection currents.^[2]^[34]^[5] Heat dynamics within the igloo can be understood through basic principles of thermal energy balance, where the heat input Q required to achieve a temperature change \Delta T is given by

Q = m c \Delta T

Here, m is the mass of the air and snow interior, and c is the specific heat capacity (approximately 2.1 kJ/kg·K for snow and 1.0 kJ/kg·K for air). The snow's low thermal conductivity confines conductive losses, ensuring that body and lamp heat predominantly maintains the elevated \Delta T rather than dissipating rapidly. Steady-state modeling confirms that conduction through the walls accounts for most heat loss, but the low k value keeps this rate below 100-200 W for a typical igloo under -40°C external conditions.^[33]^[35] The entrance tunnel functions as an airlock, with its low elevation and right-angled bend trapping denser cold air below the warmer interior air, thereby preventing convective influx of external cold and minimizing drafts. Additionally, initial internal warming causes a thin layer of the inner snow wall to melt, which then refreezes into a smooth ice glaze upon cooling cycles; this process seals pores and cracks, enhancing both insulation and structural integrity without compromising thermal performance.^[36]^[34]

Structural Engineering Aspects

The igloo's dome geometry approximates a catenary curve, the natural shape formed by a hanging chain under its own weight, which efficiently distributes gravitational loads evenly throughout the structure by channeling forces into pure compression along the curve.^[37] This shape minimizes bending moments and tensile stresses, allowing the snow to bear the weight of the overlying blocks without requiring internal supports or tension-resistant materials. The compression process during construction further densifies the snow, enhancing its structural integrity, with compacted snow achieving compressive strengths typically ranging from 1 to 5 MPa depending on density and temperature.^[37]^[38] In engineering terms, the spiral stacking of snow blocks forms a self-supporting arch, where each layer leans gradually inward toward the center, creating interlocking keystones that lock the structure in place and prevent outward collapse under load.^[6] This progressive corbeling technique ensures that the dome's curvature tightens at the apex, distributing vertical forces horizontally into the foundation while the catenary profile resists sagging. The fundamental stress in the arch can be expressed as \sigma = \frac{F}{A}, where \sigma is the compressive stress, F is the applied force (primarily the weight of the snow), and A is the cross-sectional area of the wall; the snow's compressive strength of 1-5 MPa comfortably supports typical dome loads without failure or need for an internal frame.^[37]^[39] Over time, the igloo's walls can thicken through cycles of partial melting on the interior surface followed by refreezing, forming a denser ice layer that bolsters compressive capacity and overall durability.^[23] In stable Arctic conditions, a well-constructed igloo may endure 3-6 months before gradual sagging from creep or environmental shifts compromises its form, though regular maintenance extends usability.^[40] The dome's geometry also contributes to thermal insulation benefits by trapping air pockets, as explored in related analyses of heat retention mechanics.^[37]

Modern Applications

Contemporary Uses and Adaptations

Following the widespread adoption of permanent housing options in the mid-20th century, traditional igloo construction among Inuit communities experienced a significant decline, largely due to government-sponsored relocation programs and the introduction of prefabricated structures like Styrofoam igloos designed to address overcrowding and harsh weather challenges.^[41]^[42] By the 1950s, igloos were rarely used as primary dwellings, with many younger generations losing the knowledge passed down orally, as modern amenities reduced the practical need for temporary snow shelters.^[25]^[5] In the 21st century, igloo building has seen a revival driven by cultural preservation efforts and the growth of adventure tourism, where Inuit elders teach the skill to younger community members to maintain ancestral practices amid environmental changes.^[43] Programs in Arctic Canada emphasize igloo construction as a way to reconnect with heritage, while tourism operators offer guided experiences that blend education with experiential travel, such as building sessions near glaciers in Greenland.^[44] Modern adaptations of igloos have emerged in eco-tourism, particularly in Canada and Alaska, where fiberglass or glass-domed structures mimic traditional designs to provide insulated viewing platforms for the northern lights without relying on snow. For instance, Borealis Basecamp in Alaska features private fiberglass igloos elevated on stilts, allowing guests to observe auroras while minimizing environmental impact through reusable materials.^[45] Similar setups in Yukon's Northern Lights Resort use heated glass igloos integrated into wilderness settings, promoting low-footprint tourism that supports local conservation.^[46] Hybrid igloo designs incorporating canvas or plastic have gained popularity for festivals and events, offering portable, weather-resistant alternatives to pure snow builds. Inflatable dome tents made from durable PVC or Oxford cloth, often with LED lighting, serve as venues for outdoor gatherings, weddings, and exhibitions, providing quick-setup enclosures that echo the igloo's dome shape while enhancing visibility and comfort.^[47] Innovations in igloo construction include tools like the ICEBOX Igloo Building Kit, a lightweight, adjustable pole system that guides the formation of uniform snow blocks for precise dome assembly, making the process accessible for non-experts in varied snow conditions.^[48] This packable device, developed for backcountry use, allows for igloos up to 11 feet in diameter and has been praised for revolutionizing emergency shelter building by simplifying the spiral layering technique.^[49] Scientific expeditions continue to employ igloos or igloo-inspired shelters for polar research, particularly in the 2020s, where they provide mobile, low-impact bases for climate studies in remote Arctic areas. In Antarctica, modern fiberglass "igloos," such as the Australian-designed "Apples" huts, serve as laboratories and accommodations for teams studying ice dynamics and other research, as used by the Australian Antarctic Division since the 1980s.^[50]^[51] Practical applications of igloos extend to survival training programs, where participants learn construction as a core skill for wilderness emergencies. Courses offered by the Boreal Wilderness Institute in Canada teach Inuit and modern igloo techniques alongside snowcave building, emphasizing site selection, block cutting, and ventilation for safe overnight use in subzero temperatures.^[52] Similarly, Narwal Northern Adventures in Nunavut integrates igloo building into broader survival curricula, including fire-making and foraging, to prepare adventurers for Arctic travel.^[53] Igloos also inspire contemporary art installations, transforming the structure into a symbol of impermanence and human adaptation. Italian artist Mario Merz's series of over 30 igloos, exhibited at venues like Pirelli HangarBicocca in Milan, uses materials such as iron, clay, and neon to explore themes of nature and nomadism, with works like Igloo di Giap (1968) featuring inscribed poetry on hemispherical frames.^[54] These installations, often site-specific, highlight the igloo's geometric form as a metaphor for global interconnectedness.^[55] Commercial "igloo hotels" in Scandinavia, operational since the early 2000s, represent a fusion of tourism and architecture, with seasonal reconstructions attracting visitors for immersive winter stays. Norway's Sorrisniva Igloo Hotel, rebuilt annually since 2000, offers themed ice rooms along the Alta River, combining traditional snow-block techniques with artistic sculptures for an authentic yet luxurious experience.^[56] Sweden's ICEHOTEL in Jukkasjärvi, evolving from a 1989 prototype, now spans the size of a football field with 20 suites, emphasizing sustainability through melted-water recycling.^[57]

Cultural Legacy and Representation

The igloo stands as a powerful symbol of Inuit resilience, embodying the adaptability and ingenuity of Arctic peoples in the face of harsh environmental challenges and cultural disruptions. Inuit art, such as Pudlo Pudlat's 1975 print Shaman’s Dwelling, depicts the snow house alongside syncretic elements like Christian crosses, illustrating how traditional structures represent cultural endurance amid colonization and modernization.^[58] This legacy is preserved in museum exhibits, including Janet Kigusiuq's 1971 print Building An Igloo at the National Museum of the American Indian, which highlights Inuit architectural traditions from Baker Lake, Nunavut.^[59] In Nunavut, large-scale igloo constructions like the 2021 Qaggiq in Iqaluit serve as communal demonstrations of Inuit engineering and artistry, reinforcing cultural heritage.^[60] Discussions around UNESCO's intangible cultural heritage have included Inuit practices, as seen in the 2018 inscription of the Aasivissuit–Nipisat site, which encompasses traditional hunting grounds and knowledge systems tied to Arctic dwellings.^[61] In media, the igloo has become an iconic representation of Inuit life, most notably in Robert J. Flaherty's 1922 documentary Nanook of the North, where a staged igloo-building sequence centers family survival and shelter, profoundly influencing ethnographic filmmaking despite its orientalist portrayals of Inuit as "timeless primitives."^[62] The film features Nanook constructing an igloo to emphasize technical mastery, though interiors were enlarged for the camera, blending collaboration with fabrication.^[63] Children's literature often incorporates igloos to educate on Inuit culture, as in Jan Reynolds' 2003 book Living in an Igloo, which follows a young girl's family and explains temporary snow dwellings based on real experiences.^[64] Advertisements have further popularized the igloo motif, with the Igloo coolers brand launching campaigns like "The Cooler Brand" in 2025, evoking the structure's insulating qualities through playful, durable product designs tied to outdoor enjoyment.^[65] Educational programs leverage igloos to teach Arctic engineering principles, integrating them into school curricula on STEM and cultural studies. For instance, the WWF's Arctic Science series includes hands-on lessons on igloo construction, using diagrams to explore snow's insulating properties and Inuit innovation.^[66] In the 2020s, climate education initiatives highlight igloos as exemplars of traditional knowledge adapting to global warming, contrasting their efficiency with modern challenges like melting permafrost, as discussed in University of the Arctic reports on sustainable Arctic practices.^[67] Popular culture has perpetuated misconceptions about igloos as permanent Inuit homes, often ignoring their role as temporary winter shelters in favor of exotic stereotypes.^[68] Since the 2010s, Inuit artists have actively reclaimed these narratives through works that challenge media distortions, such as those addressing colonial representations in outlets like National Geographic.^[69] Efforts include art-driven initiatives for narrative sovereignty, like those promoted by the Inuit Art Foundation, which use contemporary pieces to correct stereotypes and affirm cultural agency.^[70]
