She had given birth to her cubs, and was waiting for them to grow strong enough to follow her out to the ice pack.
Effects[ edit ] Marine mammals have evolved to live in oceans, but climate change is affecting their natural habitat. Ocean warming will therefore lead to increased species migration, as endangered species look for a more suitable habitat.
If a species cannot successfully migrate to a suitable environment, unless it learns to adapt to rising ocean temperatures, it will face extinction.
Sea level rise is also important when assessing the impacts of global warming on marine mammals, since it affects coastal environments that marine mammals species rely.
Primary producerssuch 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. Water temperature changes also affect ocean turbulence, which has a major impact on the dispersion of plankton and other primary producers.
Thermohaline circulation is responsible for bringing up cold, nutrient-rich water from the depths of the ocean, a process known as upwelling. The biggest issue for polar bears related to climate change is the melting of ice as a result of increasing temperatures.
When the ice melts, polar bears lose their habitat and food sources. Although polar bears have been known to eat more than 80 species of animals, most of their diet consists of sealswhich are also endangered by global warming.
