When people talk about global environmental problems, they commonly to regard Global Warming as the greatest problem confronting the future survival of humanity. There are countless scientific evidences showing the dangers, especially to the environment, and one of the most notable consequences of Global Warming is the impact on polar bears. Since polar bears are terribly affected and they are losing their icy habitat, they have become an iconic animal of Global Warming and have drawn a lot of attentions from publics, experts and medias. Though polar bears are good swimmers, pictures of polar bears on an isolated ice sheet at the peril of drowning when the ice sheet melts are often used to represent the tragic consequences of Global Warming on the frozen ecosystems. This formed a suspicion that is climate change really threatening polar bears. Therefore, this paper will show that Global Warming has obvious and multiple impacts on the polar bears; in spite of many facts showing them being endangered, there are some people claiming of them being fine.
Global Warming, a significant change in climate and temperature, is caused by accumulation of carbon in the

In reality, the polar bears are facing real risk of extinction since the Global Warming has ruined their way of life; for instance, it mismanaged their foraging behavior, creating more difficulty for the bears to capture their preys. Couple with unpleasant climate that they must adapt to live with. Regrettably, their icy home is melting resulted by the climate and there is no sign of this incident being stopped. Although, it can be stopped only if every individuals aware of this unfortunate incident and greatly lessen Greenhouse gases
Introduction The Ochotona princeps, better known as the American Pika or Pika, is a small, little creature that is becoming one of the upcoming symbols of global warming ("American Pika"). The O. princeps are beginning to suffer from global climate changes to their habitat in the Western mountains of the United States ("American Pika"). In an experiment by Anna D. Chalfoun, Daniel F. Doak, and Leah H. Yandow, the effects of habitat and climate change on the Pika abundance in two mountain ranges is tested to see how global warming is impacting the species (Chalfoun. Doak, and Yandow).
Polar bears are considered one of the cutest animals in the world and are adored by thousands of people. Not only are they adorable, but they are also going extinct because of the warming temperatures in the Arctic. But what mankind does not know is that warmer climate isn’t the only thing killing off these animals; it’s truly cannibalism. This surprising truth is revealed in a similar way in Rod Sterling's short story, “Monsters Are Due On Maple Street.” The story takes place in an ordinary neighborhood that is supposedly being attacked by aliens.
Have you ever wondered why particularly in Alaska, bears need to stock up on food before winter comes? all the bears particularly in Alaska, need to stock up on food before winter comes because when winter hits food goes away. In the text it states " When the cold Alaskan winter hits, the bears’ food supply disappears. Temperatures drop, freezing the streams where tasty salmon swim. The berries that the bears snack on vanishes".
As a consequence, these animals are now forced to spend more time on shore scavenging for food, often going without while awaiting new ice to form in the fall. There is also growing concern for polar bear cubs that are thought to be incapable of swimming the increasingly greater distances in open water between shrinking ice floes. As evidence, they offer the growing number of very young polar bear carcasses that they notice being washed up on shore. Many mother bears also appear to be dangerously thin and less able to fend for themselves and their young. This situation is quite noticeable among polar bears along the western shore of Hudson Bay, especially around the town of Churchill Manitoba, a location where polar bears traditionally spend the late months of fall foraging on shore awaiting the freeze-up, a freeze-up that now comes later each year.
The amount of arctic sea ice is declining more than ever. Polar bears are being greatly affected by the decreases in sea ice. (Doc A) This is affecting their diet because without enough sea ice it has been very difficult for them to catch seals to eat. Also, their population is decreasing due to the longer periods between hunts.
Almost anyone who will read this essay has undoubtedly heard of the climate phenomenon Global warming. Global warming is a topic that gets discussed very often nowadays, most notably during political debate and discussion. Politicians use certain stances on global warming to appeal to voter’s emotions and logic in order to gain votes and support for their campaign, however climate change is nothing new, during the past several hundred thousand years the Earth has heated up and cooled down and even experienced so called “ice ages”, which is a period where glacial deposits located at the northern and southern hemispheres have grown due to dramatic global cool downs. Don’t be confused by climate terminology though, the global warming so widely
Document A states, "Climate change is warming the Arctic along with the rest of the planet — and in the Arctic, that means sea ice is melting," (DA) This is important for many reasons. Document A claims, "Sea ice is crucial for polar bears survival," and that "Most scientists agree that these trends spell likely trouble for polar bears. " This shows that the Arctic melting impacts polar bears and other Arctic animals, but that is not the only reason the artic melting is bad. The Arctic ice melts into water and Document H shows that millions of people all around the world would be flooded out of their homes.
Apart from the sea ice, the polar bears have very few alternatives left when the ice melts and when their access to the ringed seal prey disappears with their habitat. The charismatic arctic hunters cannot adjust and sustain themselves on another food source. If the devastating process of climate change continues, there wouldn’t be a thin sheet of ice left for these extraordinary animals to survive
Sea level is now rising by 3.1mm per year. At this pace, more than 2.5 m sea level rise by 2040. How does climate change affect Arctic animals? Climate change affects Arctic animals drastically by destroying their living habitat and food sources. Polar bears are having a hard time finding food because the ice caps are melting.
As the world we live in today continues to warm up, the problems surrounding the survival of the world’s beloved polar bear continues to grow. Over the past twenty years, we’ve seen a change in the number of polar bears in the Arctic and have witnessed a decrease of the amount of Arctic ice in the sea. Many scientist have come up with ideas to tackle the problem, but there hasn’t been a solution that has greatly influenced the predicament at hand. Ultimately, when discussing what to do about the endangered animals, it is valuable to consider what the species needs in order to remain; a healthy population and genetic diversity. Andrew Derocher, biologist at the University of Alberta, and the rest of his team have come up with a few ways to combat these needs.
Global warming is a big problem that we have to face nowadays. If you search Google for the word “global warming’, you will get over 70 million pages of results. The subject has certainly drawn a lot of attention. And now I will talk more about “what is global warming” , the cause and the effects it has on the earth and also some possible solutions for this problem.
Climate change, specifically warmer temperatures, has extensively altered these habitats by reducing sea ice extent, thus affecting polar bears since they use it as a platform to travel, hunt, and rest. Changes in the timing of sea ice formation and break up limits the amount of time bears can feed off of seals during late and early summer, hence limiting the amount of fat they are able to store for later seasons. Lower rates of food intake and storage correlates to low reproductive rates, and since females do not have sufficient fat and mass required for successful parturition, they abstain from
What is global warming? Global Warming is the increase of Earth 's normal surface temperature due to impact of greenhouse gases such as carbon dioxide radiations from lighting fossil fuels or from the removal of trees which lure heat that would otherwise get away from Earth. This is a kind of greenhouse impact. Global warming is the determined and relieved increases in the mean temperature of Earth atmosphere and oceans.
Global Warming causes and solutions The majority of scientists around the world have a fear of global warming and its effects on nature and humans around the world. Global warming is considered as one of the most threatened in our world today. This essay presents and explains the impact of global warming on earth and suggests to finding the best solutions can be done in order to minimizing those reason that affected on raising the temperatures to avoid this problem.
Global climate change constitutes arguably the single most important threat to mankind. From the onset of the industrial revolution, greenhouse gas emissions (GHGs), including carbon dioxide (CO2) have increasingly built up in the atmosphere, causing the climate to warm up slowly but steadily (IPCC, 2014). NASA predicts that 2016 will mark the hottest year on record. The effects of global warming are ubiquitous: Greenland’s glacier and the Arctic ice cap are melting, ocean levels are rising, occurrences of extreme weather are increasing, including hurricanes and areas of either intense drought or flooding. Collectively, these changes and their direct consequences are an imminent danger and they directly affect other urgent issues humanity is
