The Effects Of Global Warming On The World

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.

Polar Bears rely upon sea ice for survival. They hunt on seals that are found on sea ice. Climate change and the atmospheric warming have caused the Arctic ice to melt, resulting in loss of habitats for polar bears. This essay will focus on how has climate change and increase in temperature affected the polar bears and what can we do about it.

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

The latest survey conducted by the US Forest Service shows that as many as 97% of the animals of the Arctic could be affected as a result of the observed warming. The climate change may occur faster in the Arctic region. Scientists have developed computer models to predict changes in the environment and their impact on the 162 species of birds and 39 species of mammals in the Arctic.

Melting of the ice caps --- loss of habitat near the poles. Polar bears are now thought to be greatly endangered by the shortening of their feeding season due to dwindling ice packs.

polar ice caps are melting, resulting in habitat loss for animals such as polar bears.

Climate change is one of the most crucial issues in the twentieth century. There is much evidence to show fluctuations in weather occurring on the earth. Scientists found that the period of global warming is occurring more frequently than the previous time and rapidly increasing temperature globally. The statistic records on the nineteenth century, calculated that the surface of earth throughout the 100 years ago that had average increase of approximately 0.8C. However, during the period thirteen years ago, the average temperature increase around 0.6C and continually warming with an upward trend in the shortest period. These events cause drastic changes which affect human life such as extreme weather (hotter and colder), food and fresh water shortages and higher levels of the ocean. It is important for people to being concern what happens now. This essay will focus on the main cause of anthropogenic changing climate, in order to evaluate and link the outcome of activity.

Summary Polar bears are an important arctic species that are in danger of extinction because of climate change. Polar bears are known as a keystone species, meaning they have significant effect on the environment in which they live. As such, keeping polar bears alive is essential for a balanced ecosystem in the Arctic Circle. One of the major threats to polar bears is melting sea ice. As the overall temperature of the earth increases due to global warming and the greenhouse effect, the sea ice that polar bears live on for most of their lives is melting.

Global Warming has been questioned by many people on whether it is actually real or fake. It is very obvious that it is real because a lot of the Arctic sea ice has been melting over the last few years. Another very obvious sign that global warming is happening is many animals are struggling to deal with it, therefore the size of their population is decreasing every year. One example of an animal that’s population is starting to contract with global warming in effect are polar bears. According to the WWF polar bear population is decreasing around the area with the melting Arctic sea ice. The sea ice is melting because of global warming, which directly gives the polar bears a disadvantage because they utilize the ice to live as well as hunt

How Does Climate Change Impact the Lives of Arctic Animals? Growing up, I had always heard people talk about global warming and climate change. I never really understood what that meant, and I felt like it didn’t concern me. Over the summer I visited the San Diego zoo and I was very fascinated by the polar bears. I vas also intrigued by the the zoo’s habitats for the animals that were used to living in a colder climate. The zoo had managed to make those animals feel comfortable even in sunny San Diego. I was recently asked to do a research project of my choice. I wanted to do something that interested me, but I just couldn’t think of anything. Then, I thought back to my trip last summer and remembered how interested I was in the polar bears. This led me to the question, “How does climate change impact the lives of Arctic animals?”

Polar bear is the largest land carnivore in the world, it is an animal native to the Arctic. They live without definite residence but migrate across the ice and through the seas from Russia to Alaska, Canada to Greenland and onto the Svalbard archipelago. Adequate food and energy are the key for polar bear to survival in the harsh arctic environment. In recent years, however, the polar bears have faced enormous challenges in arctic, where they have no natural enemy. It is well known that the normal temperature of human body is around 36.5 degree centigrade, sometimes, sudden illness causes a rise in body temperature. Every sudden increase in temperature of human body is a threat to human health. The same is happening with the global climate system. On the surface, the temperature is just a fraction of degree centigrade but the air temperature can be changed very severe during a certain period and it also causes a chain reaction of weather and climate. The Intergovernmental panel on Climate Change (IPCC) reports that since the industrial revolution, the average temperatures of Earth surface has risen by 0.6 degree centigrade (Lisa V. Alexander). Moreover, the rise in temperature is concentrated in recent decades, there has been an upward trend of about 0.2 degrees Celsius per decade. Global warming has already affecting the Earth’s ecosystems. The polar bear was the first species be listed as a threatened species in the US under the Endangered Species because of the threats

Throughout many years, our Earth’s climate has changed and fluctuated many times. As of today, our climate has been increasing dramatically. This has to do with burning too many fossil fuels and creating more greenhouse gases, which make the Earth absorb more sunlight from the sun’s rays. Although this is hurting humans, no one has really thought about how it is affecting the arctic animals. It has affected polar bears and their way of life. Climate change is also affecting lemmings, and the way they use the snow to survive. The Arctic Fox has a new competitor, the Red Fox. Climate Change is affecting the biodiversity of animals and could cause a major extinction.

Polar bears also use the sea ice as a resting place or a place to give birth. As global warming is increasing, the sea ice is melting from being in a hot and rainy climate. Therefore, polar bears are having trouble locating food to eat. One of the main reasons why polar bears do not have the food necessary to satisfy could be because of the over population of polar bears during the hot climate. (Stirling & Parkinson, 2006) Granted that there is not much food for the bears, when there is food, most of them must fight over it because of its limited amounts. When polar bears cannot find any food near the sea ice, they are forced to look further in order to survive. If global warming worsens, it is possible that polar bears will go extinct. “Scientists predict that the polar bear population, currently 20,000 to 25,000, could disappear by the end of the century.” (Diane Cole, 2009) Although there are some lack of national and international policy agreements, global warming may affect not only wildlife but us humans as well. “The expert responses suggest polar bear population and range will undergo significant declines by 2050 under SRES A1B.” (O’Neill, Osborn, Hulme, Lorenzoni & Watkinson, 2008) A study was done to show empirical evidence about polar bear body mass and weight to see how long polar bears can survive without food. The study concluded that the earlier in the year that the climate gets hotter, the longer the polar bears suffer. (McCarthy, 2015)

Geoengineering is the on purpose mass manipulation of the environment, in an attempt to stop or slow down the effects of global warming. It is being used as we speak to help save the atmosphere and slow global warming. Although it’s known that global warming is changing the planet for the worse, is Geo-Engineering the best way to fight it? Global Warming is melting our ice caps and sea levels are constantly rising at an alarming rate. If it is not combatted many major cities will be wiped off of the planet. The world has been combating geoengineering for a while with emitting chemtrails one among many of ideas. Although many ways are quick and relatively cheap, they all have their downsides.

Climate change doesn’t just mean that certain species will suffer from the loss of habitat. There will be a cascade effect up and down the food chain, affecting the most basic species of prey and apex predators alike. Dominant predators with a strong preference for a carnivorous diet are arguably more vulnerable to destruction of their environments. If the prey population suffers, it directly affects the survival of the predators that depend on them. Polar bears have an especially focused diet, and seals are their prefered prey. Interestingly, the milk produced by polar bear mothers “is more similar to that of pinnipeds (seals) than it is to milk of most terrestrial mammals” (Amstrup, 599). Like polar bears, several species of seal depend on a reliable presence of sea ice in order to breed (Derocher 2004, p. 168). A dwindling seal population will almost certainly affect polar bears.
