Which factor does NOT contribute to local extinction?

Global climate change can influence biodiversity and species habitats on a large scale, but it does not directly lead to local extinction in the same manner as the other factors listed. Habitat destruction, species migration, and overpredation are more immediate threats that can directly result in the decline of a specific population in a local area.

Habitat destruction removes the necessary resources and environments that species need to survive, effectively making it impossible for populations to thrive. Species migration can lead to local extinction when individuals leave an area in search of better conditions, potentially causing the population in the original location to dwindle if they do not return. Overpredation can decimate local populations by significantly decreasing their numbers when predator species overpower them.

In contrast, while global climate change can affect ecosystems and shift species distributions over time, it does not single-handedly create a local extinction event as the other factors do. Hence, global climate change stands out as a broader, less immediate factor that might influence extinction dynamics but does not directly contribute to local extinction on its own.
