How Does Global Warming Affect Polar Bears

The melting sea ice is also affecting the polar bear's main prey, seals, forcing the bears to turn to alternate, less nutritious food sources. Once sea ice forms in the winter, seals use the ice to create dens to give birth to their pups. In these months, polar bears use sea ice as their hunting grounds to find seal dens. Now that Seasonal Ice is forming later and melting earlier (IPCC, 2013), seals have less time to build dens and give birth. Consequently, polar bears have less time to hunt their preferred prey of seal pups. They must spend more time on land hunting other animals of less nutritional value. Organizations like Sea World Parks have reported male polar bears occasionally eating newly-born polar bear cubs because they cannot find other food to eat. Lack of nutritional food leads to a reduced body size. Polar bears are becoming thinner and weaker from not eating enough (Rode, Amstrup, & Regehr 2010). They have to swim longer distances to find ice to hunt upon, causing many cubs to die because they are not yet strong enough. In the Hudson Bay, the average polar bear weight has decreased by 15% and the population has decreased by 20% (National Wildlife Federation). In the summer when there is no ice, polar bears in the Hudson Bay go onto land to fast until the ice reforms. Now that ice is

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 about 100 different species of animals there, all of which are affected by climate change, but polar bears the worst. Polar bears are the most sensitive to the rapid change in climate because most of their life is spent on sea ice. With the temperatures rising in the Beringia Upland Tundra, the sea ice they thrive on is melting at a very high rate (Powell). Without this ice, the polar bears will not be able to easily move around to mate with other polar bears. They will also not be able to successful hunts on seals because the seals will see them swimming and swim away before anything bad can happen to them. If there was not a shortage of ice, the seals would not see the polar bears on the ice and they would swim closer to the surface. Another challenge the polar bears will face is that they will be eventually forced to go on to the seashore. This would be catastrophic because there would be and increase of competition for food. This could start massive stampedes that could kill polar bear cubs due to adult polar bears trampling them. As of now, there are only 26,000 wild polar bears alive. By 2050, it is predicted that two thirds of all wild polar bears will be gone. By 2100, it is predicted that polar bears will become extinct if nothing is done about global warming and climate change (Kliskey). Another animal in the Beringia Upland Tundra that is affected by climate change in

Another point he makes is that Polar bears are getting scrawnier because the seal habitat has declined because global warming causes the ice to melt. This is false. A common fact global warming supporters forget to mention is that arctic and Antarctic snowfall replenish the ice each year. Polar bears and seals are more in danger of poaching than losing their habitat to global warming. Both species are on the endangered list. However, weighing anywhere between 775 to 1,200 pounds. Polar bears are still the largest species of bear living on the planet.

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

With the ever rising global temperatures, melting ice caps, and constant warnings about global warming, it is no wonder that the animals inhabiting the artic regions around the world are now suffering a decline in their habitat as well as their livelihood. Such is the case with the Polar Bears who may soon be gone in a scant few years.

Polar bears diets mainly rely on seals so the current changes in ice will affect the life cycle of the seals as well as it will play a big role in the life cycle of an adult polar bear. A large decrease in adult polar bears has been noticed and is believed to have been noticed and is believed to have been caused by the ice changes over the last few years as the decline in the seal population results in the polar bears being hungry during the winter which means they are not storing enough fat to produce energy to keep them alive all winter resulting in the polar bears unable to survive the cold winter months without their natural food source (Prowse et al,

Global warming is the steady heating of Earth’s land, oceans, and atmosphere caused primarily by human activity. Climate change is one of the world’s biggest challenges right now, from people actively arguing that it doesn’t exist- to other’s who don’t care enough to do anything about it. There’s evidence showing that climate change is happening and affecting our world now and from what it seems, if action isn’t taken, major consequences will soon arise. Most of the world’s land mass has experienced a 0.2-1.0 degree Celsius average temperature increase since the 1970s, the temperatures of the Artic has increased at almost twice the mean global rate. Climate change is caused by human factors such as greenhouse gases and ozone depletion and because humans are so dependent on fossil fuels in their day to day lives, the issue at hand is only going to get worse.

Scientists say that the melting of Arctic ice and ice caps are harmful to essential life of arctic animals like polar bears because they live on Arctic ice and ice caps (Rinkesh). Research has proven both of these theories wrong. The Arctic ice and ice caps have increased and are still increasing. Since 2012, the Arctic ice and ice caps have increased in volume by fifty percent (Foley). There are over twenty thousand polar bears in the world and over sixty percent of these polar bears live in Canada (Matishov). The population of polar bears is increasing and staying at a stable rate, depending on their location (Global Warming and Polar Bears). Since, both of these theories have been proven wrong, we do not believe that “global warming” is affecting the Arctic ice or Arctic

There are a lot of things that are impacted such as farming, it is affected by global warming because GW (short for Global Warming)will shrink the amount of water in lakes and then a flash flood will happen and kill the crops that we need to eat to survive. Another thing is acidic rain, it also can be dangerous to the crops by using the pollution that is picked up in the clouds when the rain is coming down. It also impacts industry’s because the industry’s resources will soon be gone and we will all become poor and hungry. Also The glaciers are going to melt and cause flash floods.

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 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).

The concerns about the ever rising sea levels, melting ice caps, and constant warnings about global warming making their way into everyday news and our lives, it is no surprise that bears inhabiting the arctic regions are now suffering as a result. The extent of the damage done to the Polar Bears may mean they'll soon be gone in a scant few years.

There is a serious situation is occurring on planet Earth that is causing a significant and harmful effect on communities, health, and the climate. It is Global Warming which can be defined as the constant heating of Earth 's surface, oceans and atmosphere. In order to understand global warming, the most important basic is to figure out how the of greenhouse effect plays an important part in its development. The greenhouse effect is caused by increased levels of carbon dioxide (CO2) that trap heat in the atmosphere that keeps the Earth warm. The information this text will discuss is the meaning of global warming, the causes, and most importantly how citizens can help to rectify the situation. Humanity must tickle this problem immediately before the consequences increase and affect the entire planet.
