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 d="M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z"/> Subscribe on YouTube

  • 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.
