How does the climate change affect the global distribution of fauna?

Climate change is a result of rapid global warming. The increase of average temperature of earth is termed as Global warming. Global warming is a natural process which has been accelerated by anthropogenic activities. Because of this earth is not getting time to adjust to this change. This is causing climate change.

Effect on fauna:

  • Migratory roots are changing for the birds. For example The arrival of Siberian cranes in India is delayed and they are returning to Russia a bit early.
  • The breeding pattern of birds and aquatic animals is also changing. Tropical fish species are shifting to more temperate waters.
  • Vector borne diseases which were found in tropical areas are also shifting to temperate regions.
  • There is a large scale habitat loss. This is the single biggest reason of pushing species to the brink of extinction. Many endemic species which are confined to a small area likeislands have become critically endangered. Right now, 6th mass extinction is going on.
  • Many polar species are finding it uncomfortable to survive in the polar waters because temperature is increasing.
