Final answer:
Anthropologists treat global climate change in a local culture by studying its sociocultural effects, documenting challenges faced by the community, analyzing strategies to mitigate climate change, and using holistic analysis and cultural relativism.
Step-by-step explanation:
Anthropologists treat global climate change when dealing with a local culture by practicing climate ethnography and studying the sociocultural effects of climate change in specific regions. They examine how previous modes of subsistence have become impossible in climate-sensitive areas and document the challenges faced by local communities, such as droughts, floods, and crop failures. Anthropologists also analyze the strategies employed by these communities to mitigate climate change, such as switching crop species or adapting traditional practices. They use holistic analysis techniques, cultural relativism, and collaborative approaches to understand and represent the local culture's experiences with global climate change.
