How Does Global Warming Affect Polar Bears

The article “Melting Ice Threatens Polar Bears ' Survival” by Katie Madan is about the melting icebergs and how it is threatening the polar bears survival. The department of interiors are making a decision on putting the polar bears on the endangered species list, a study shows the Polar bears in beau fort sea region in Alaska and Canada are going to go extinct soon. The bears need there ice as a platform to hunt for their food such as seals or fish, if they cant hunt for food then they will die of starvation thus making them extinct. The population of the polar bears having been decreasing by 25 percent per year. Katie’s purpose for this article was to show people what is happening to these polar bears because of global

Climate change is a huge issue around the world. It is melting the polar ice caps, which is rising the sea level wiping out cities along the coastline. Also because of the ice caps melting many animals that live on it are going extinct. The animals that don’t live on the ice caps are also going extinct because they can’t adapt at the alarming rate that the climate is changing. Some animals are starting their migration earlier and other animals are going to higher elevations (higher than they should) to get cooler weather. There are some creatures that are thriving because of the heat, one of them is the bark beetle. The bark beetle is killing off trees by eating at the inner bark cutting off its circulatory system, leaving the trees with little to none nutrients to live on. Another thing that is killing off trees is wildfires. The amount of

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

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.

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

The earth is heating up 500 billion tons of ice will collapse. Then one and a half feet of sea level will rise and then the water would move 150 feet inland in Florida. If this keeps up the world will slowly but surely heat up. Without humans trying to help the environment the world could flood. Some of the problem is Human responsibility and how it is ruining the earth and how the environment and nature will fall because of Global Warming.

Firstly, the deers search for food in areas warm enough to sustain plants, but cold enough for ice to cover the sea, for their migration. The climatic changes because of global warming may have affected the plants and other vegetation in the Canadian Arctic. The plants which were food for the deers may have been destroyed by the unfavorable conditions, resulting from the global warming. Along with it, due to decreasing

Life for grizzly bears will get worse threw out time with more conflicts that will end up with dead bears.

According to The National Park Service, most of the glaciers in Alaska are experiencing thinning and retreating. (National Park Service, 2015) Meaning that the ice is melting and becoming

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

In early July and late June native and local hunters, Ross Schaeffer and his niece Karmen Schaeffer Monigold have motored through the broken sea ice in north-western Alaska, on the hunt for seals lounging on frosty rafts to find temperatures were close to 70 degrees, there was no ice in sight, and the seals had surprisingly already migrated north. This seal-hunting season was the shortest in reminiscence, lasting less than a week, compared with the traditional three weeks. Carbon dioxide in our atmosphere now sits at 400.7 parts per million. Artic ice has dissipated by more than 13% since 1880. Land Ice is disappearing at a frightening rate of 287 billion metric tons per year.

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. They use the ice to rest on while hunting for seals, but since there is less ice it’s causing the polar bears to drown from exhaustion. Walruses can eat up to 200 pounds of clams each day. Clams are usually found near the continental shelf but with ice caps melting it is getting harder for walruses to find

Oil explorations and oil spills are posing serious threats to polar species, resulting in severe risks to both marine and terrestrial ecosystems and wildlife. Polar bears, the chief predators in the Arctic marine ecosystem, are affected by exposure to oil followed by oil spills. Even though oil pollution and the ratio of spills in the Arctic are on a low level at present, during 1993 to 2007, many oil spill incidents were reported, most of which were the consequences of extreme collisions, groundings, and sinking accidents, leading to long-term consequences to polar species, and even a chance of extinction for polar bears. While there are no tested and operative

Global warming is causing the glaciers to melt specially in rise in sea level would destroy the plants and other species as the area would get over-flooded. The animals would die from hunger due to the deterioration of forests and plants. Ultimately the people who have survived the flood and heat would suffer at the hands of hunger as the only two sources of food we have would get destroyed due to global warming.

Climate change has major effects to our world that a lot of people don’t realize. Global warming is a major threat for the habitat in the Arctic. The Arctic is warming twice as fast as the rest of the world because the shiny snow and ice is reflecting more of the sun’s energy but as the ice and snow disappears, the water and rock are absorbing the heat and this is known as the albedo effect. As the glaciers, snow and ice melt, sea levels will rise which can cause erosion and destroy habitats. Also, the Arctic habitat hosts many species itself, such as polar bears, arctic foxes, and walruses. Without these land masses, hunting, mating and resting are harder to do which results in the species dying out. There are also many droughts that are occurring which affects many species including humans. Many ponds that contain wildlife are drying up and many freshwater bodies are being depleted. Not only are animals being affected by this but
