Researchers found that most of the polar bears are losing weight, about 0.4 to 1.7 kilograms per day. ... Thanks to climate change, polar bears are not getting enough to eat.
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.
"The Arctic is one of the fastest warming regions in the planet," said Flavio Lehner, chief climate scientist for Polar Bears International and assistant professor at Cornell University, who ...
Fifteen years after polar bears were listed as threatened, a new study says researchers have overcome a roadblock in the Endangered Species Act that prevented the federal government from ...
As a result, the diet is less nutritional, which leads to reduced body size and reproduction, thus indicating population decline in polar bears. [92] The Arctic refuge is where polar bears main habitat is to den and the melting arctic sea ice is causing a loss of species. There are only about 900 bears in the Arctic refuge national conservation ...
Russia's World Wildlife Fund said "Today, polar bears are entering human areas more frequently than in the past and climate change is the reason. Global warming is reducing sea-ice and this phenomenon forces polar bears to come to land in order to find new sources of food". [3]
Polar bears are expected to decline along with sea ice as climate change proceeds, but it’s possible that glacial ice like this could provide some refuge for small groups of polar bears, Laidre ...
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."
