Answer: Warming temperatures are causing animals to move toward the poles and higher altitudes in search of cooler climate. Some species will be able to adapt. Others such as polar bears will not.
How do warming temperatures affect animals that live in cold climates?

Allen's rule predicts that endothermic animals with the same body volume should have different surface areas that will either aid or impede their heat dissipation. Because animals living in cold climates need to conserve as much heat as possible Allen's rule predicts that they should have evolved comparativ …

Changes in temperatures will impact the location of areas with high primary productivity. Primary producers such as plankton are the main food source for marine mammals such as some whales. Species migration will therefore be directly affected by locations of high primary productivity.

Thu Jan 22 2004 13:30:00 GMT-0500 (Eastern Standard Time) · The earliest explanation given by Bergmann when originally formulating the rule is that larger animals have a lower surface area to volume ratio than smaller animals so they radiate less body heat per unit of mass and therefore stay warmer in cold climates. Warmer climates impose the opposite problem: b...
