Another impact of global climate change on the Arctic ecosystem has been changes in animal migration patterns. As temperatures rise, some species are moving farther north in search of cooler temperatures, while others are being forced southward. These shifts in migration patterns can have profound effects on the entire food chain, as predators and prey are forced to adjust to new living arrangements.
