What is one natural consequence of changes in global climate?

One natural consequence of changes in global climate is that animals could migrate north, but the habitats they move into will likely be different from those they originally occupied. As temperatures rise due to climate change, many species are forced to move towards the poles or to higher altitudes in search of suitable conditions. However, this migration does not guarantee that the new habitats will provide the same resources, climate, or ecological relationships that the animals have adapted to in their original locations.

For example, as glaciers melt and temperatures increase, forests may replace tundra, altering the types of food and shelter available to species that depend on the tundra ecosystem. This shift can lead to competition with other species and may affect survival rates if the migrated species cannot adapt quickly enough to the new environment. Thus, while mobility is a critical response to climate change, the altered nature of the new habitats presents significant challenges for the animals involved.
