Climate change exposes animals to a variety of stressors, influencing metabolic and endocrine functions, with potential consequences for the survival of species. With climate change, more animal species are going extinct every year. Approximately 700 mammals and birds are impacted. The degree of vulnerability varies by the type of animal and different species will be affected in different ways. Species with low tolerance for rising temperature are vulnerable to extinction. The vulnerable/endangered animals include polar bears, koalas, elephants, sea turtles, cheetahs, panda bears, and penguins (non-exhaustive list). Climate change can cause habitat degradation or loss for several species (e.g., polar bears, koalas, and birds). 
Survival of species can be affected by water/food availability/quality beyond those that species can tolerate. Unpredictability/shortage of water and food caused by climate change may lead to greater prevalence of torpor and hibernation in small mammals and hypometabolism in large mammals.
Also, warmer springs have promoted advanced timing of migration and breeding in most avian species in the last decades.
