How does the climate affect the polar bear?

Answer 1

Global Warming(Heating)---> Ice melting---> Less Place for Polar Bears to hunt and live---> Polar bears dying and drowning

Should ice start to melt in any real quantity in the Arctic, polar bears would migrate further north. The little ice that we have seen melt in the area appears to have been good for them do far as there numbers have gone up exponentially. From a low of 800 many decades ago, we see they have reached between 25,000 and 27,000 now. This means they are not on the endangered species list presently.

They ARE listed as a threatened species. Should the Arctic begin to melt to any degree, some groups believe this could then threaten their survival.

Answer 2

no because they are not black bears and not brown bears polar bears are white and will stay white only until they go to zoos they get grayist at zoos because they are not in their own habitat and it changes the color of them that why polar bears do not change colors but in zoos they DO!!!!!!!!!!!!!!!!!!!

Answer 3

• Global warming is melting the sea ice in the Arctic.
• Polar bears rely on long winters of frozen ice to hunt seals (in dens under the ice).
• They need good reserves of food (blubber) to last them through summer when they can't hunt seals.
• Winters are getting shorter and the ice is melting earlier.
• Bears are weaker and summers are longer, so some move to land and scavenge in rubbish bins.
• Weaker female bears can not bear and raise cubs successfully.
• We are burning the oil and coal that is causing global warming. We have to change to renewable energy!

The ice that the polar bears need to hunt for food is melting. So that means they can't eat. If they can,t eat, the population of the polars bears will become extinct. A:The polar bear population is still growing and no science group claims they are not. They number over 25,000 from a low of 800. Some groups claim that global warming could someday affect these bears.

The population has risen, from approximately 10,000 in 1960, to over 22,000 today.

A:There are no ice caps for them to live on, and where are they meant to go which isn't thousands of miles away to swim? They would all probably drown. See the related question below.
It could someday affect them greatly, scientists predict that as the Arctic temperature continues to rise due to climate change (global warming), two thirds of the world's polar bears could disappear by mid-century.

The polar sea ice is shrinking each year. Each year the winter sea ice melts faster. Polar bears need to bulk up in winter by eating seals. Now they have a shorter time for feeding. The Hudson Bay bears are forced onto the land during summer where they compete for food and living space with humans and other animals. Food shortages mean that bears are weaker, fewer cubs are born and those that do are more likely to die.
Global Warming effect has serious consequences for all living organisms, but it is of especially great concern for the polar bear. According to the US Geological Survey Office, reduction in sea ice in the Arctic can see a loss of 2/3rds of the entire word's Polar Bear population over the next 50 years.
what has happened?

scientist have seen an an alarming increase of polar bear drowning (from 2004). Since polar bears are basically good swimmers, researchers were puzzled how and why they drowned.

Investigations soon showed that the combination of fewer and smaller ice floes and erratic climate changes have contributed to this situation.

The main cause of global warming is said to be emissions from burning fossil fuels. Although this is not the only cause for global warming, it is one of the main causes of temperature change.

Answer 4

It threatens the bears and then they become an endangered species.

Answer 5

Many bears will be nearly prone to extinction, so if the whole race of polar bears temperature rose up then it would be a risk of mass extinction.

Answer 6

Global warming has very negative effect on polar bears. It reduces the size of the ice sheets they live on and thus many drown looking for food and solid ice to live on.
