What Is Happening To Polar Bears

Polar bears have long been the poster child of the consequences of climate change. The crux of the matter is that different claims are made based on scores of assumptions.

Will Polar Bears Die Out Because Of Climate Change

Polar bears rely on sea ice to hunt seals rest breed and store energy for the summer and autumn when food can be scarce.

What is happening to polar bears. While rapid loss of sea ice is the primary threat to the polar bears long-term survival other challenges include pollution increased commercial use of the Arctic overharvest disease and inadequate habitat protection denning and seasonal resting areas. Polar bears rely on sea ice to hunt and store energy for the summer and autumn when food can be scarce. As the bears spend longer periods without food their health declines.

The climate change has devastating effects on the existence of polar bears. At night they are invisible. Polar bears help us gain an understanding of what is happening throughout the Arctic.

So what does this mean. Polar bears are black with clear fur so in daylight they appear white. Polar bears may revert back to being subspecies of the brown bearThis plausability never happens in nature.

The bottom line is that polar bears for the above reasons should be listed as Endangered in the US. Polar bears and narwhals are particularly vulnerable to the threats from climate change. Regardless of how many bears may have been around at times past however as long as temperatures warm and sea ice habitat continues to decline polar bears ultimately can only decline.

July 20 2020. Young Polar bears stay with their mothers for 12 years and they become mature when they are 56 years old. To minimize their energy consumption the bears still-hunt waiting for hours by seals cone-shaped breathing holes in the sea.

I believe the polar bear will go extinct this century because of Global Warming. As the bears spend longer periods without food their health declines. Polar bears live alone.

Polar bear population was believed to be endangered especially due to global warming and melting of sea ice. Wild polar bears will become extinct unless we take action to reduce greenhouse gas emissions. Scientists say some populations have.

Over the past few decades the rise in temperature threatens the very existence of natural Arctic habitat. All recent indicators show that sea ice in the Arctic is melting at an alarming rate a problem that needs to be addressed immediately if polar bears and other species unique to the region are to survive. The majority of a polar bears diet is made up of seals that live on and around the edge of the sea ice like ringed seals and bearded seals.

Sea ice now melts earlier in the spring and forms later in the autumn in the bears southern range like Hudson Bay and James Bay in Canada. True the extent of summer ice has diminished. As Arctic sea ice melts their hunting and eating patterns have had to shift threatening their survival.

Sea ice now melts earlier in the spring and forms later in the autumn in the bears southern range like Hudson Bay and James Bay in Canada. However recent study shows polar bear numbers have risen. Polar bears will be wiped out by the end of the century unless more is done to tackle climate change a study predicts.

Polar bears have long captured our attention but probably at no time in the past have they been more in the forefront of the publics attention than today. Polar bears hunt on the ice stalking seals as they lounge on icebergs or surface for air at a breathing hole. The international organization Polar Bears International predicts that if current warming trends continue in the Arctic two-thirds of the worlds polar bears could disappear by 2050.

A new study now suggests the Arctic species is at risk of being starved into extinction by the end of the century. They have been saying for decades the Arctic ice may be gone soon making it impossible for polar bears to hunt seals in the winter and spring. Polar bears rely almost exclusively on a calorie-loaded diet of seals.

Are polar bears endangered or not. Polar bears should really be called ice bears because ice is key to their survival. All these studies are approximations and further detailed studies are yet to be.

Sea ice disappears in warmer months and in winter the ice could not refreeze in a. Polar bears could become nearly extinct by the end of the century as a result of shrinking sea ice in the Arctic if global warming continues unabated scientists said Monday.
