Human insecurity almost never has single causes, but instead emerges from the interaction of multiple factors. {12.1.2, 12.2} Climate change is an important factor threatening human security through (1) undermining livelihoods {12.2}; (2) compromising culture and identity {12.3}; (3) increasing migration that people would rather have avoided {12.4}; and (4) challenging the ability of states to provide the conditions necessary for human security. {12.6} Climate change will compromise the cultural values that are important for community and individual well-being ( medium evidence , high agreement ). The effect of climate change on culture will vary across societies and over time, depending on cultural resilience and the mechanisms for maintaining and transferring knowledge. Changing weather and climatic conditions threaten cultural practices embedded in livelihoods and expressed in narratives, world views, identity, community cohesion, and sense of place. Loss of land and displacement, for example on small islands and coastal communities, has well documented negative cultural and well-being impacts. {12.3.1, 12.3.3, 12.4.2} Indigenous, local, and traditional forms of knowledge are a major resource for adapting to climate change ( robust evidence , high agreement ). Natural resource dependent communities, including indigenous peoples, have a long history of adapting to highly variable and changing social and ecological conditions. But the salience of indigenous, local, and traditional knowledge will be challenged by climate change impacts. Such forms of knowledge are often neglected in policy and research, and their mutual recognition and integration with scientific knowledge will increase the effectiveness of adaptation. {12.3.3-4} Climate change will have significant impacts on forms of migration that compromise human security ( medium evidence , high agreement ). Some migration flows are sensitive to changes in resource availability and ecosystem services. Major extreme weather events have in the
