A changing climate has strong implications for biodiversity. Studies of fossil and pollen distribution show that species are very sensitive to climate changes. When the climate changes, species often die out in their present areas and colonize new areas. Therefore, as the climate changes in the future, there will be disruption of natural communities and extinction of populations and species.

Based on the information above, which of these would most likely be affected by a global warming?
A) Rattlesnakes in the desert.
B) Polar bears living on the sea ice.
C) Earthworms burrowing in the ground.
D) Spider monkeys in the tropical rain forests.

Answer: B) Polar bears living on the sea ice.

Global warming is a natural phenomena which involves the increase in the global atmospheric temperatures because of the human activities such as deforestation, burning of the fossil fuels and others. Terrestrial as well as aquatic animals and other life forms are directly or indirectly are affected by global warming. Global warming is related with the melting of the global glaciers.

The polar bear is a species of bear which is a native of Arctic glacier region. These animals are adapted to survive in the harsh winter conditions of the Arctic region. The change in the climatic conditions in the Arctic region due to global warming will directly influence the population of these animals in a negative sense. These organisms have thick coat and consists of heavy body fat, they cannot survive in hot summer conditions.
