On Thin Ice: Polar Bears

There are about 100 different species of animals there, all of which are affected by climate change, but polar bears the worst. Polar bears are the most sensitive to the rapid change in climate because most of their life is spent on sea ice. With the temperatures rising in the Beringia Upland Tundra, the sea ice they thrive on is melting at a very high rate (Powell). Without this ice, the polar bears will not be able to easily move around to mate with other polar bears. They will also not be able to successful hunts on seals because the seals will see them swimming and swim away before anything bad can happen to them. If there was not a shortage of ice, the seals would not see the polar bears on the ice and they would swim closer to the surface. Another challenge the polar bears will face is that they will be eventually forced to go on to the seashore. This would be catastrophic because there would be and increase of competition for food. This could start massive stampedes that could kill polar bear cubs due to adult polar bears trampling them. As of now, there are only 26,000 wild polar bears alive. By 2050, it is predicted that two thirds of all wild polar bears will be gone. By 2100, it is predicted that polar bears will become extinct if nothing is done about global warming and climate change (Kliskey). Another animal in the Beringia Upland Tundra that is affected by climate change in

There are so many consequences because of global warming and humans polluting. As a result of global warming, the polar bear habitat is getting demolished. The warmer temperatures are melting the ice in the Arctic and North Pole. Polar bears are travelling miles and miles to find ice. Polar bears live, eat, and raise their cubs on Arctic ice, which is breaking up and melting at an alarming rate. Year by year, this problem will get worse and worse. Humans and factories throw away their waste in the ocean and it goes in the water the fish and animals drink. Polar bears eat fish and they are affected by this polluted water as well. Hunters kill many animals including the polar bears and it’s decreasing their population. When polar bear population decreases, other animal populations will rise and the animal chain will change. We should not let global warming take over our species and destroy the animal chain. Polar bears are one of the many animals affected and if there are too many animals affected, the whole animal chain will fall apart. Research shows that, even if steps are taken to reduce emissions now, gases already in the atmosphere will continue to heat up the earth for another 40 to 50 years. Scientific statistics indicate they may suffer extinction by year 2100. We still have many years to make a

With the ever rising global temperatures, melting ice caps, and constant warnings about global warming, it is no wonder that the animals inhabiting the artic regions around the world are now suffering a decline in their habitat as well as their livelihood. Such is the case with the Polar Bears who may soon be gone in a scant few years.

The Polar Bear are found on the icy coasts that surrounds the North Poles and as far south as Hudson Bay. Around 60%of Polar Bears can be found in Canada with the remainings throughout Greenland, Alaska, Svalbard, and Russia where tend to be close to the ocean across the icy fields. The habitats are affected by human encroachment by hunting , and releasing chemical pollutants into the water.The Polar Bear eats Seals, Walrus, and Seabirds. Polar Bears can live up to 20-30 year. Polar Bears have a lot of fur and their fur is clear, white, or yellow. The Polar Bear is 6.5 ft-8.3ft. they can weigh up to 330lbs -1,322lbs and they can swim up to 25mph.

Land Survey that found that polar bears could be gone in 40 years if measures weren't taken. Siegel additionally made the point that an oil slick would be calamitous for the polar bear populace and that given the late inconvenience in the Gulf, Alaskans shouldn't take the danger.

Regardless of the studies continuously being done on the polar bear and brown grizzly bear lineage, the polar bear is listed as “vulnerable” which is one level below “endangered” on the International Union for Conservation of Nature List. This is due to the warming climate, loss of sea ice, threats of hunting, shipping, and pollution (Hailer, Verena, and Bjorn, 2012).

This week, a viral picture of a sickly polar bear is causing debate all over the world about climate change. Although the issue is not strongly affecting humans just yet, it is influencing wildlife all over the globe. Polar bears, in particular, have been the focus of concern for various organizations that are making it their mission to protect the endangered species. Now more than ever, it seems the polar bear really needs humans to reconsider the choices being made about the environment.

The polar bears are losing sea ice for their habitation. Polar bears live in countries around the Arctic Circle, these areas included Canada, Alaska, Greenway, and Norway. There are 19 identified populations of polar bears living in four different sea ice regions across the Arctic. The Artic surrounds the North Pole however, the ice is melting and darkening of the artic. There is supporting evidence about air pollutions and how the greenhouse effect is affecting the polar bears environment. Polar bears will eventually only have one last stronghold left for them and even then, researchers do not know how long that one will even last. The last stronghold for them are small islands in the middle of Canada called the Artic Archipelago. This is

The polar bear (Ursus maritimus) is the biggest terrestrial mammal in the Arctic. He is also considered as an animal with a circumpolar or broad distribution in polar regions. The conservation status of bear remains problematic, according to the global warming that is happening now. If further managements are not implanted, polar bear population`s will disappear in the future. The polar bears live in the Arctic, an ocean surrounded by land. The Arctic has a very low species diversity and polar bears the first animal into the food chain. Also, the Arctic has cold winters which are not suitable for some aquatic species. With global warming and interglacial period, the ice and snow began to recede about 20.000 years ago. The rate of ice loss has

Polar bears are one of so many animals that are going extinct . The polar bear is a bear who is a carnivorous whose native range lives in the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. The polar bear is going extinct for many reasons but the main reasons is that there is ongoing and potential loss of their sea ice habitat because of climate change.According to WWF “Polar bears were listed as a threatened species in the US under the Endangered Species act in May 2008. The survival and the protection of the polar bear habitat are urgent issues.”

The polar bears are dying rapidly, and if we don’t start thinking about the environment then they will blow out to extinction. Polar bears, known as the bears of antarctica, are magnificent animals. They are the top consumer for most prey. Without them, the secondary consumer would overpopulate and eventually lose control and take over.

Overall, male and female polar bears have their own ways of hunting and foraging. Although the females have their physical limitations due to size or their cubs, they still find a way to survive like the males do by feeding off carcasses and hunting. Climate change is the other limiting factor that is changing the way polar bears forage, but is also providing new ways as well through nesting grounds. As the world keeps changing, the polar bears are changing as well to adapt and survive the best way

emigration) in order to adapt to the changing climate. As observed specifically in the Alaskan Beaufort Sea region, there is an increase in polar bears sighted on land, namely in the coast and open water area. Since the polar bears need to be on ice to feed, of which much is thin and lost, the polar bear population has essentially been forced to emigrate to land in order to survive (Kovacs, 2010). Although these polar bears have been able to adapt to the changing climate with changes in their migration, the changes can result in damage. Polar bears are not always able to adapt to their land setting, and need to receive adequate nutrition, which is lacking on land due to the inabilities of acquiring marine mammals, their traditional diet. Along with likely drops of populace, many scientists estimate that polar bears will be forced to make, “long migrations from traditional winter ranges to remnant high- latitude summer sea ice… may ultimately preclude bears from seasonally returning to their traditional ranges (Kovacs, 2010).” There is a chance for polar bears to need to be adaptive to the point of changing their region of migration radically. For polar bears to tread to such locations, there is a chance that there will be a drastic change in an extreme specie and geographical way; both the geographical makeup of the polar bears’ habitat can change along with the specie itself (i.e. survival of the fittest and further adaptations in the possible scope of diet

Polar bears can smell prey on ice up to 20 miles away.polar bears live in countries that are around the Arctic Circle. Polar bears do not live in Antarctica.Polar bears habitat is in a place where the ice is continually melting and refreezing and has Open Spaces in the ice to catch their prey.

The main cause of global warming is “greenhouse effect.” Greenhouse effect is gases that are released into the atmosphere that do not escape into space, the gases that contribute are: water vapor, nitrous oxide, carbon dioxide, and methane. “The most important greenhouse gas is carbon dioxide, emitted by the burning of fossil fuels, and the clearing of forests” (Climate Change). The stronger greenhouse effects are it will warm up the Earth, and ocean’s causing glaciers, and other ice to melt increasing sea level (“A Blanket”). When ice melts, and glaciers start to disappear it is hard for polar bears to live because the remaining ice that is left gets farther from shore. It makes it harder for polar bears to hunt, and can be brutal to them as they try to swim back because of such big waves the glaciers cause. ). “In 2004, biologists discovered four drowned polar bears in the Beaufort Sea, and suspect the actual number of drowned bears may have been considerably greater” (“Global Warming”). When those four polar bears were out in the sea, they were probably looking for food, and since the ice is melting is it makes it extremely harder for them to hunt. Polar bears eat walruses, narwhals, beluga, whales, and many types of seals. Polar bears “still-hunt” which is to sit silently, and watch for prey to go to a breathing hole, when they come up for air that’s then the polar bear strikes (Sionger). Polar bears do everything on the ice, they rely on it to hunt, sleep, and live
