Polar Bears Ringed Seals Analysis

Global Warming is an ongoing problem in the world which causes the average global temperature to increase near the earth surface. This has affected many animals, especially the polar

It implies that polar bears are transitioning to become marine mammals, which is incorrect. They are already well adapted for their lifestyle, but if global warming continues perhaps something new will happen.

One of the more debated and controversial topics in modern time is whether climate change really has an effect on animal life and the environments they live in. There are numerous sources of evidence on both sides supporting many theories and trying to determine whether climate change actually has an effect on animal life can be hard. In the following paper, we will discuss how it has a negative effect on animals like polar bears and how their population sizes are decreasing due to environmental changes like the the ozone layer and the melting ice caps.

My name is Zachary Rowe, I am going to talk about the global warming weather effects in Alaska and how it has affected the population of various living animal species. The number of large predators living in the southern Beaufort Sea of Alaska has decreased from 1,500 animals in 2001, to just under 900 in 2010. As the species are decreasing in numbers, they are now listed as vulnerable by the International Union for the Conservation of Nature. Another problem in 2013, a report by the National Oceanic and Atmospheric Administration have seen a decline in reindeer inside Alaskan boundaries. These aren't the only species whose populations has

Polar bears are one of the countless species who are endangered. They were one of the first animals affected by global warming and their population is heavily decreasing. Around 1980, the Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the Arctic? Scientist predict by 2040, only a fringe of ice will remain in Northeast Canada and Northern Greenland. This is known as the Last Ice Area. This matter is mostly taking part in Canada, since; Canada holds more than half the world’s polar bear population. Other affected countries include the U.S. (Alaska), Greenland,

Glacier retreat will greatly affect polar and aquatic ecosystems and animals. Most arctic life revolves around the sea and presence of sea ice. Without the presence of ice, most ecosystems will be recreated. Polar bears are one species in great danger. Polar bears use sea ice as a birthing and hunting ground, and also use it to travel from one place to another. As glaciers start to disappear, the mother polar bear has less access to food; therefore, the chance of survival for her and her young is very slim. The polar bears chance of reproduction becomes less as the glaciers retreat. As the top of the food chain, their decline will cause negative effects for each level below them (Review Diagram G). The only way for polar bears to survive, is by

The Arctic region has been experiencing increasing warming throughout the last thirty years, which has led to the changes to lake and river systems, and the melting of permafrost. These changes and the continuing changes, caused by global warming have raised concerns about its effects on wildlife populations that rely on the northern lake ecosystems, such as loons. Loons rely on freshwater lakes for nesting their young, and the invertebrate and fish that live in the lakes use the habitat for food. This effect on Loons can be compared to other animals around the Arctic region, and how the warming is affecting them.

In the scientific article, “Love in the Time of Climate Change: Grizzlies and Polar Bears Now Mating,” by Adam Popescu, believes that climate change is helping to cause grizzlies and polar bears to mate. He points out that glacier sheets are retreating, this forces the polar bears to move into grizzly’s territory. Moreover, that the permafrost is also starting to melt, which is causing grizzlies to wander into the polar bears territory. Consequently, he goes on to put that because of this mating, the grizzlies are eating up the polar bears genetically. He concludes that if this trend keeps up, in a few decades any kind of the bear population in this area will be no more. Lastly, the author’s purpose is to make readers aware of the hidden effects

The polar bear lives up in the Arctic region where global warming and climate change are melting the ice caps that the bears thrive on. They use the ice as a platform from hunting and rest. The random pocket holes in the ice, where the seals pop up at, is where the polar bear catches its prey. With this reduction of ice, “the abundance of seals, and increases the amount of energy and time needed for hunting, leaving less energy for reproduction” (Endangered Species and Habitats).

Using the film and their theories, Bears shows the possible outcomes of Climate Change in Alaska and on the bears, and how they affect the other. Michael Carey emphasizes the idea that people once thought of Alaska as an “unchanging, eternal face,” but now consider it the “center of national and international climate change discussion.” Monika P. Calef treated Alaska’s Climate Change and what Bears portrays from a vegetation perspective, claiming that with the decrease of tundra areas due to Climate Change, forested areas were growing due to Alaska’s warmer temperatures, as well as causing other habitats to change and give other resources. Lowell H. Suring with his ideas of human impact related that other environmental factors influenced the “availability of important foods” for bears. Each of these articles relates to how Bears change what Alaska means to us as an unchangeable wilderness to a wilderness that is changing due to Climate Change. In addition, Bears means to us that Climate Change will not only change the life of the Alaskan bears, but it will change the lives of those who are also in our environment and any others in the future that come after

The most well-known climate change must is the global warming due to the inclination of greenhouse gas in atmosphere, which is a common issue for all human beings and ling creatures. For examples, the melting of arctic glaciers, one of the most critical consequences of global warming, has caused severe damage to the species diversity of the living creatures of entire Arctic Circle. Polar bears and seals are two of most influenced living creatures in Arctic Circle since their habitats have been highly eliminated and invasive creatures have severely negative influences on their life. Now, although many countries have acted to rescue polar bears and seals, but scientists predicted that their situation would continuously worsen in the future.

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

Sea Ice is frozen sea water floating on the surface of the ocean. This figure shows the Arctic Sea Ice extent which has decreases significantly throughout the year. The graph shows in 1979-2000 the lowest the sea ice extent reached was 7 million square kilometres. In 2007 the lowest the sea ice extent reached was 4 million square kilometres in September. This would have a major impact on the polar bears hunting. The Arctic sea ice has decreased 14% since 1970s. n 2012, the Arctic sea ice extent hit the lowest ever recorded. By 2040, summer sea ice would be limited to the northern coast of Greenland and Canada. This is the Last Ice Area. This decrease in Sea Ice throughout the year has impacted on the lives of polar bears in this region. The polar bear species are rapidly reducing due to the melting of their habitats. The Sea Ice is thawing which is resulting in an increase in drownings because polar bears have to travel further distances to hunt for prey but get too tired before they reach another ice sheet. Polar bears rely on sea ice to rest and breed. A study published in Ecological Applications analysed data on polar bears in northwest Alaska and Northwest Territories which shows there was a 40% decrease in population between 2001and 2010 from 1500 to 900 polar

Polar bears are the most known animals for the impacts of climate change on species. Global warming has been most prominent in the Arctic, and this trend is expected to continue. Their dependence on sea ice makes them highly vulnerable to a changing climate. Polar bears greatly rely on the sea ice environment for traveling, hunting, mating, resting, and in some areas, maternal dens (WWF). Specifically, they depend heavily on sea ice-dependent prey such as seals. Additionally, their long generation time and low reproductive rate may limit their ability to adapt to changes in the environment. Every time people breathe or burn something, oxygen in the air is converted to carbon dioxide. The carbon dioxide is used by plants to breathe and is converted back to oxygen, creating a cycle. If there is an increase in oxygen burning, for example, burning a lot of coal or oil to generate electricity or run cars, and cut down trees, the amount of carbon dioxide in the air is increased. This makes the air thicker and warms up the earth. The amount of warming is only a few degrees but it is enough to disturb the fragile balance of nature, which in turn will melt the polar ice, raise sea levels, cause violent hurricanes and endanger species such as polar bears. The polar bears are just one example of endangered animals because of the high demand of human need for energy which is acquired by burning fossil fuels.
