How Does Global Warming Affect Polar Bears

Global warming -- and climate change -- have long-term and short-term impacts on our environment. Caused by air pollutants such as carbon dioxide and methane, global warming is the gradual increase of air temperature across the globe. The rise in air temperatures can lead to higher extinction rates, increased risk of disease and political repercussions, such as wars over available resources. Understanding the possible short-term and long-term effects can help humans better prepare for the consequences of global warming.

This first study helps me answer my question regarding climate changes affect on polar bear reproductive success because it directly addresses the reduction of body size and cub recruitments as a result of sea ice decline, due to climate change. This information provides a correlation between climate change and sea ice decline. By completing the study, a direct correlation between decline in optimal ice habitats and reduction in maternal condition was found based on body weight and size. In addition, they found that maternal condition directly impacts the number and survival of offspring. By combining all the results it is adequate to conclude, according to this study, that climate change is lowering the reproductive success of polar bears by decreasing sea ice; therefore, decreasing maternal condition and leading to reduced reproductive output and juvenile success.

Global warming is the recent and ongoing rise of temperature on a global scale. Over the past century, the Earth's average temperature has risen 1.4°F (Carlowicz, 2010). Global warming is the effect of an excessive amount of greenhouse gases in the atmosphere. Greenhouse gasses trap heat from escaping back into space to keep the Earth from freezing, this is called the Greenhouse Effect. An excessive amount of greenhouse gases in the atmosphere trap too much heat, thus, causing Earth's temperature to rise.

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.

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,

Global warming is the rise of average temperature in the earth’s atmosphere since the late 19th century. Since the beginning of the early 20th century, the earths mean surface temperature had increased by around 0.8 degrees. Warming of the climate system had become more obvious and scientists are 90% sure that the main cause of the increase in temperature in due to the increasing concentrations of greenhouse gases due to human activities such as deforestation and burning of fossil fuels.

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

Global warming affects polar bears in antarctica by making the icebergs melt. It make them have to swim for a long time in the ocean to get to a iceberg to rest. It also causes less polar bears to survive. There is also not enough food for the polar bears and its family. we can stop global warming by using cars less to get around so that the pollution does not go into the air. You can use less electricity and use the energy from the sun. you can use less water from the sink or the shower. You can use less heat. To stop that we can use hydroelectric power, solar power, and wind

The U.S Fish Wildlife Service says that Polar Bears are declining, and are becoming endangered. 22,000 to 31,000 Polar Bears are now roming the world. Studies have shown that these bears are going to be extinct because of the ice that are melting. The Atlantic bear usually make their dens in the ice and snow. However, because of Global Warming the icebergs are melting, causing the dens harder to live in for the bears. I believe we should do more to help these bears from becoming extinct by stopping Global Warming, and clean the environment, and starting a club.

Polar bears are affected by global warming in a bad way because they need sea ice to stay alive. Sea ice helps polar bears catch food by finding openings in the ice to find fish or seals.Polar bears can't live in hot climates. Polar bears are endangered because of global warming and if it does not stop they will go extinct. The ice is also the polar bears habitat, they need this ice to sleep on too. Humans can stop global warming by planting trees and plants, buying solar panels, donating money to stop global warming, and more. Do you want this beautiful animal to be

The polar bear is the largest known land animal that eats meat. With black skin, and light reflecting fur, it is capable of a lot of things with its adaptations. Adult polar bears can weigh over 1,400 lbs and can grow up to 10 feet tall. With this, they can use their unbelievable strength to catch prey like sea lions, walruses, etc. Polar bears have adapted to swim up to 100 miles (6 miles an hour). Though, you may think they are cold most of the time; they’re not. Polar bears tend to overheat more than getting too

Global warming is an increase in the temperature of the earth's weather. Global warming is also known as the green house effect. Global warming is a very serious world issue. Most humans are trying to do as much as they can to help stop global warming. Global warming has caused many problems to the earth in addition to the humans that live here on the earth. A problem caused by global warming is very hot summers. Some summers have had days that the temperature had reached 30*C. Another Problem that global warming has caused is the melting of polar ice caps. Global warming caused the polar ice caps to melt which will cause the ice to break free as well as melt in the sea, sea levels all over the world will rise. Lastly,

The first thing I want to start off with is telling you what global warming is and give you an idea of what it can do to our planet. Global warming increases temperature all around the world. It also put a lot more carbon dioxide in the air by us humans. Pollution of Carbon dioxide is one is the most common one and is mostly caused by running vehicles exhaust, burning of fossil fuels such as coal,and factory smoke.when we let carbon dioxide in the air it has nowhere to go except in our atmosphere. therefore is causes rising temperature to build up in our atmosphere over time slowly.

Global warming has become a world wide issue and an issue that is causing great controversy. It is an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution (Dictionary). Global warming is a natural process, but because of increase in certain activities this process is taking a faster and more dangerous route creating global problems. Global warming was first theorized in 1894 by Jean Baptiste Joseph Fourier a French mathematician, who noticed the earth was gradually increasing in temperature. He came to the conclusion that the earth’s atmosphere was trapping solar radiation caused by the sun and reflecting this radiation back to

Global warming is the constant increase of temperature in the earth’s atmosphere that is caused by the increase of carbon dioxide, chlorofluorocarbons, greenhouse gases and many other pollutants. Chlorofluorocarbons are any type of compounds of carbon, hydrogen, chlorine, and fluorine which are harmful to the ozone layer. Global warming can affect many things, one example is the rising of temperature which can result in different types of disasters like storms, heat waves, floods, and droughts. Global warming also causes Higher death rates, Dirtier air, Higher wildlife extinction rates, the increase of Acidic Oceans, and Higher seas levels. In this essay, I will provide information that will show how harmful global warming can be to not only the earth but to humans and animals, and what we can do to prevent it from increasing.
