Polar Bears And Climate Change Essay

Climate change is happening at a really fast pace. One of the affected areas is the Arctic and the Arctic life. Climate change is the change in weather patterns over a long period of time caused by global warming. Global warming is a gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants. Ever since the industrial revolution, the amount of carbon dioxide in the atmosphere has increased drastically. The large amount of carbon dioxide was produced by human activities such as burning gases, woods, and burning coal. Clearing forests also releases large amounts of carbon dioxide. Worldwide deforestation means that we don’t

Rivera, Ma. Ione Skye Niches and Adaptations Part I: Animal #1 BLACK BEARS American Black Bears are forest dwellers and are usually found in mixed forest areas and also places that can be as high as 10,000 feet in elevation. Their habitat is mainly in an understory surrounded with lots of fruits, nuts, and berries.

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.

The book “The Weather Makers: The History and Future Impact of Climate Change” written by Tim Flanner pertains to predicting the global warming consequence on earth and species. In chapter 9, the unraveling world, the author talks about global warming and how it can have a long-lasting and far-reaching impact on our lives. He points out the substantial and rapid change of the climate and its connection with the effects of El Nino and La Nina are also uncovered. Climate change can be a major contributor as to where species live and how they interact. The changes can also be observed by the changing migration patterns of these species.

Many, many animals are going endangered and even extinct because of human caused climate changing. One of those notable examples is the polar bears, which only have a population of 20,000-25,000. The reason polar bears are going extinct is because warmer temperatures in the north is causing the ice caps to melt more, and in the summer, polar bears use the ice caps to travel to get food after hibernating. But if the ice caps melt too much and break away, then polar bears

The Arctic ocean stops salt water from going to marine life when the ocean freezes, since the ocean won’t be freezing the ocean won’t be able to bring nutrients to plankton, many types of animals will die from hunger. Global Warming not only brings geological disaster but it can also cause new viruses or sickness. In the book “ Open for Debate Global Warming” by Kathiann M. Kowalski explains that the increase of heat will cause animals who like the heat such as mosquitos to become more active. “ Warmer weather could increase the geological range for insects like mosquitos. Higher temperature might increase the insect 's’ metabolism too.

Finally, changes in environmental conditions are also responsible for the collapse of the East Coast Fishery. Water temperatures have dropped and ocean salinity levels have changed, causing fish to change their migratory routes, and avoid areas that are changing. People have suggested that the increase in the seal population has reduced the amount of fish because greater quantities of seals eat greater quantities of fish. In conclusion, a number of theories such as, overfishing, destructive fishing practices, and changes in natural conditions explain why the East Coast Fishery has

Blubber If an animal habitat is located in a cold, frosty area, such as the Arctic Circle, bearing with the weather could be a challenge. Many warm-blooded animals, such as whales and seals, rely on blubber to keep their body temperatures up. Whales, for example, are constantly swimming. They could not survive in the frigid water without their blubber protecting and keeping them warm.

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).

Only later when summer is over permafrost 7: Problems and Threats:Due to global warming the tundra is starting to deplete and the biome known as tundra will be all water. Land animals cannot adapt to this so the artic fox and polar bear will be no more. Water level will be raised every where and floods could be critical to the entire

If we noticed it or not, our planet is warming up. All the way from North Pole to South Pole. Since 1906, the global average surface temperature has gone up from 1.1 to 1.6 degrees Fahrenheit, this is more noticeable in the polar regions. This effects of the rising temperatures isn’t to be taken lightly just because the average surface temperature has gone up by .5. The small change in heat is melting the glaciers, not just the north and south poles but mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.

Human bear conflict is a real problem in certain areas of the world and studies have been done to figure out why. Most people first thought of bears as being dangerous. They thought that the bears could really do some bad things to humans if they ever got their paws on us. Why was the research done over this topic? The research was done over Ursus Arctos (brown bears) because their diet and also their behavior was poorly misunderstood. Why was it an important field of study? It was an important field of study because people in the region was really concerned about the bear problem. The author’s hypothesis was that anthropogenic food would be a major component of the bear’s diet; the anthropogenic food would be lower in seasons with higher natural

Many animals, whether they live in the ocean or the arctic are affected by climate change. Climate Change affects everybody in the world, even though some choose to ignore it, which is why it would be in humanity’s best interest to come together and find a solution. Burning fossil fuels and the increase of greenhouse gases is causing the earth to warm. Although this gas is the source of the problem we still need it, without this gas the earth would be very cold. What the greenhouse effect is a layer of gas that surrounds the earth,

The Impacts of Climate Change on Species This paper seeks to research the study of climate change and its effects on biodiversity. This will be done by first understanding what climate change is and what the different effects are. Once this is understood, it will be easier to apply this knowledge to the study of biodiversity and how species are affected. Real life examples of different species that are affected will be mentioned and explained. Climate change is a reoccurring issue in our world that has been observed and studied extensively.
