The key danger for polar bears posed by the effects of climate change is malnutrition or starvation due to habitat loss.Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall.
Majestic, increasingly hungry and at risk of disappearing, the polar bear is dependent on something melting away on our warming planet: sea ice. In the harsh and unforgiving Arctic, where frigid ...
Researchers found that most of the polar bears are losing weight, about 0.4 to 1.7 kilograms per day. Climate change is starving polar bears, cameras strapped to them show Skip to main content
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).
As climate change diminishes sea ice from coastal communities in the Arctic and the subarctic, researchers expect polar bears to range farther into the towns
Seals are another marine mammal that are susceptible to climate change. [114] Much like polar bears, some seal species have evolved to rely on sea ice. They use the ice platforms for breeding and raising young seal pups.
One of the negative effects of climate change is the decline of polar bear populations. Taylor believes that "Polar bears, as a species, do not appear to be threatened or in decline based on the data that I’ve seen at the present time, although some populations do seem to be experiencing deleterious effects from climate change."
Glacier melt is forcing polar bears into the water where they must swim for days at a time to find solid ground. Climate change is forcing polar bears to swim for days on end to solid ground Skip ...
