Beluga

Belugas make such a variety of sounds—clicks, twitters, whistles, and mimics of other sounds—they have been nicknamed "sea canaries." As much as 40% of their body mass is blubber, which stores energy and keeps them warm in temperatures as low as 0 °C. The smallest whale on the planet, a baby Beluga gains up to 200 pounds a day.

Belugas live in Arctic and Sub-Arctic waters. Impacts from climate change include: an increase in ship traffic as sea ice declines, oil exploration and extraction, fisheries by-catch, and disruption of the food web. As Arctic waters warm and currents change, the Humpback (a competitor) and the Orca (a predator) may move north and stay longer. Some Beluga populations are also threatened by hunting, pollution and habitat loss.

Other animals effected by climate change

Adelie Penguin
In winter, the sun doesn't rise south of the Antarctic Circle. If Antarctic sea ice decreases and does not extend far enough to the north, Adélie Penguins, during their winter migration, may not be able to reach the sunlight needed to navigate, hunt and avoid predators—they won't dive in the dark. Other threats are oil pollution, fishing and disturbance of colonies from research stations and aircraft.

Rusty Patched Bumble Bee
The Rusty Patched is the first bee to be listed as endangered in the US. Populations have declined as much as 87% from habitat loss, disease and pesticides. Climate threats include: warming and precipitation, early snow, late frost and drought. Bees and butterflies are important agricultural pollinators. In 2016, 40% of invertebrate pollinators (bees and butterflies) were listed as threatened with extinction.

Sockeye Salmon
For decades wild salmon populations have been in decline from human causes: over fishing; habitat degradation—logging, mining, agriculture and dams; pollution; and interaction with hatchery or farmed salmon. These conditions and threats may hinder their ability to adapt to the effects of climate change. Salmon thrive at specific freshwater temperatures—warming air raises water temperature. Early snow melt and increased rains cause physical changes to spawning streams.

Emperor Penguin
In 50 years, the mean temperature of western Antarctica has risen nearly 3 °C—more than any other region—reducing the extent and thickness of winter ice. The Emperor Penguin is dependent on the ice for breeding, raising chicks and moulting. Less sea ice decreases zooplankton (krill) which feed on algae that grow on the underside of the ice. Krill are an important part of the food web for the Emperor and other Antarctic marine species.
