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.
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]
According to the World Wildlife Fund, polar bears are currently classified as vulnerable, meaning they are facing a high risk of extinction. There are roughly 22,000 to 31,000 of the mammals in ...

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 ...
In the Arctic, rising temperatures are causing a greater area of sea ice to melt and threatening the polar bear with extinction as early as 2030. Global warming is also disrupting the planet's weather systems and making seasonal rainfall patterns less predictable. This poses a threat to creatures like elephants, which must travel greater ...
International Polar Bear Day is organized by Polar Bears International to raise awareness about the impact of global warming and reduced sea ice on polar bear populations. [3] The day encourages people to find ways to reduce their carbon output, such as by turning down their thermostat or driving less. [4]
Susan Janet Crockford is a Canadian zoologist known for her research and publications on polar bears. From 2004 to 2019 she was an adjunct professor in Anthropology at the University of Victoria. [1] Crockford has gained attention for her blog posts on polar bear biology, in which she argues that polar bears are not threatened by climate change ...
