North America's climate is changing, affecting Indigenous peoples' traditional ways of life. Temperature increases, shifting precipitation patterns, and regional variations are altering ecosystems and resource availability across the continent.
These changes impact Indigenous communities differently based on location. From Arctic warming to Southwestern droughts, climate trends are reshaping landscapes, wildlife habitats, and water resources that Indigenous cultures have relied on for generations.
