• Prolonged periods of abnormally high temperatures often accompanied by lack of precipitation
• Cause severe water shortages, crop failures, and increased wildfire risks
• Disproportionately affect Indigenous communities reliant on traditional agriculture and water-dependent ecosystems
• Examples include the 2021 Pacific Northwest heat dome and the ongoing megadrought in the Southwestern United States

Severe storms and hurricanes

• Intense weather systems characterized by strong winds, heavy rainfall, and storm surges
• Cause widespread damage to infrastructure, disrupt power supplies, and lead to flooding
• Affect coastal Indigenous communities and those living along major waterways
• Examples include Hurricane Ida (2021) and the increasing frequency of atmospheric rivers in California

Floods and heavy precipitation

• Rapid accumulation of water in a specific area, often due to intense rainfall or snowmelt
• Result in property damage, soil erosion, and contamination of water sources
• Impact Indigenous communities living in flood-prone areas or near rivers and lakes
• Examples include the 2013 Colorado floods and the recurring Red River floods affecting tribes in North Dakota and Minnesota

Blizzards and extreme cold

• Severe winter storms with low temperatures, strong winds, and heavy snowfall
• Cause transportation disruptions, power outages, and increased risk of hypothermia
• Particularly challenging for Indigenous communities in remote areas with limited access to resources
• Examples include the 2021 Texas winter storm and the frequent polar vortex events affecting northern tribes

Causes of extreme events

• Understanding the causes of extreme weather events is essential for Indigenous communities to develop effective adaptation strategies
• This knowledge helps in predicting future trends and informs policy decisions that affect tribal lands and resources
• Recognizing the interplay between natural variability and human-induced changes is crucial for comprehensive climate action

Climate change factors

• Increased greenhouse gas emissions lead to global warming and altered atmospheric circulation patterns
• Rising global temperatures contribute to more frequent and intense extreme weather events
• Melting Arctic sea ice affects jet stream patterns, potentially causing more persistent weather conditions
• Examples include the amplification of heat waves due to higher baseline temperatures and increased atmospheric moisture leading to more intense precipitation events

Natural climate variability

• Cyclical patterns and oscillations in the Earth's climate system influence weather patterns
• El Niño Southern Oscillation (ENSO) affects temperature and precipitation patterns across North America
• Pacific Decadal Oscillation (PDO) influences long-term climate trends in the western United States
• Examples include the drought-inducing La Niña events and the wet El Niño phases affecting the Southwest

Human-induced environmental changes

• Deforestation and urbanization alter local and regional climate patterns
• Land use changes affect surface albedo, evapotranspiration, and local temperature regimes
• Air pollution and aerosols impact cloud formation and precipitation patterns
• Examples include urban heat island effects in rapidly growing Indigenous territories and altered rainfall patterns due to large-scale agricultural practices

Impacts on Indigenous communities

• Extreme weather events pose significant challenges to Indigenous peoples in the North American West, threatening their cultural heritage and livelihoods
• These impacts intersect with existing socioeconomic disparities, often exacerbating vulnerabilities within tribal communities
• Understanding these impacts is crucial for developing targeted adaptation strategies and advocating for Indigenous rights in climate policy

Disruption of traditional practices

• Altered seasonal patterns interfere with traditional hunting, fishing, and gathering activities
• Changes in plant and animal migration patterns affect traditional food sources and medicinal practices
• Extreme events damage culturally significant sites and landscapes
• Examples include disrupted salmon runs due to warming rivers and changes in wild rice harvesting seasons in the Great Lakes region

Food and water security

• Droughts and floods impact agricultural yields and traditional food systems
• Extreme weather events contaminate water sources and damage water infrastructure
• Changing climate patterns affect the availability and quality of traditional food sources
• Examples include reduced access to traditional foods like acorns in California due to drought and contaminated shellfish beds from increased coastal flooding

Health and safety risks

• Extreme heat increases the risk of heat-related illnesses, particularly among elders and children
• Increased wildfire smoke exposure leads to respiratory problems and other health issues
• Flooding and storms pose immediate physical dangers and long-term mental health impacts
• Examples include higher rates of asthma in Indigenous communities near areas prone to wildfires and increased cases of vector-borne diseases due to changing temperature and precipitation patterns

Economic consequences

• Damage to infrastructure and property from extreme events strains tribal resources
• Disruptions to traditional economic activities like agriculture and tourism impact tribal economies
• Increased costs for disaster preparedness and recovery divert funds from other community needs
• Examples include the economic impact of recurring floods on tribal casinos along rivers and the loss of income from climate-affected traditional crafts and artisanal products

Traditional knowledge vs scientific data

• Extreme weather events interpreted as messages or responses from the natural world
• Cosmological understanding of climate cycles and their relationship to human activities
• Examples include the Thunderbird in many Northwest Coast cultures associated with storms and the Hopi belief in Kachinas controlling weather patterns

Ceremonial responses to extremes

• Rituals and ceremonies performed to address or prevent extreme weather events
• Prayer and offerings made to maintain balance with natural forces
• Communal gatherings and traditional practices as a form of spiritual and psychological resilience
• Examples include the Sundance ceremony among Plains tribes to ensure rain and abundance, and the use of rain dances by Southwestern tribes during periods of drought

Intergenerational knowledge transfer

• Oral traditions and storytelling used to pass down weather-related knowledge and adaptive strategies
• Elders' roles in interpreting signs of extreme weather and guiding community responses
• Integration of traditional weather knowledge into formal and informal education systems
• Examples include the use of winter counts by Plains tribes to record significant weather events and the incorporation of traditional weather knowledge into tribal school curricula

Policy and governance

• Effective policy and governance structures are crucial for addressing the impacts of extreme weather events on Indigenous communities
• Tribal sovereignty plays a significant role in shaping disaster response and climate adaptation efforts
• Collaboration between tribal, federal, and state entities is essential for comprehensive climate action

Tribal sovereignty in disaster response
