Polar Bears: No Natural Threats

Improved Essays
To survive, polar bears require the cold and snow of the arctic, hence the name “polar bears”. Polar bears have little to no natural threats in their habitat, and are in fact at the very top of the food chain. Polar bears aren’t threatened due to poaching or predation, they are threatened by us. Humans treating the earth as if its something that we can take for granted indefinitely. It isn’t indestructible, in fact it’s the exact opposite, a very delicate balance, and humans have greatly increased the amount of carbon in the atmosphere. Using core samples in the arctic, scientists can gather useful data about the weather atmosphere and even the temperature, they can gather data from up to 420,000 years. The core samples can also be used to

    The ice core sample is harder to retrieve than a tree ring. Ice cores show all seasons, where tree rings show the growing time of the tree. There are many things that make the two methods very different. Both of these methods are very effective to conduct climate change research. Scientists are still working to improve the research methods.…

    The Evolution of Polar Bears Laysa De La Torre Polar bears have a very interesting history as they are evolved from brown bears. It is very weird how they don’t hibernate but interesting to hear what happens when they don’t hibernate. Polar bears are actually very interesting even if you may not like them, you will soon be interested after reading this. Polar bears hair is white because, the air spaces in each hair scatter light of all colors. The color white becomes visible to us when it reflects back all visible wavelengths of light, rather than absorbing some of the wavelengths.…

    Polar bear’s population in the Arctic Circle are being severely limited by climate change, food scarcity, and oil exploration. Polar bears are one of the largest land carnivores in the world, but their populations are increasing dropping due to changes in their habitat. Polar bears live on the edges of packs of ice surrounded by seas. “IUCN Polar Bear Specialist Group show that three subpopulations are in decline and that there is a high estimated risk of future decline due to climate change.” Climate change is one of the greatest threat to polar bears.…

    Throughout the past thirty years the average area covered by sea ice has decreased by about 8%, an area larger than Denmark, Norway and Sweden combined. [6] The average thickness of the sea ice have suffered some loss as well to the tune of 10-15% over the same time period. The Sea ice is a key climate indicator and an agent of climate change [7] affecting surface reflectivity, cloudiness, humidity, heat exchanges and moisture at the ocean surface and ocean…

    To get a better picture of what the weather and climate were like on a yearly basis, scientists can look to ice cores and dendrochronology, dating using tree rings. By looking at greenhouse gas concentrations in layers of ice cores, scientists can compare the concentrations to different temperatures to get an idea of the climate in the past. This can also show climate stability, cycles, and snow accumulation over the years. Dendrochronology is also used to learn about weather in the past by looking at how fast a tree grows in different conditions. This can also be helpful when dating wood found near settlements by comparing it to known tree-ring patterns from different time…

    How Is Global Warming Affecting the Polar Bears? As changes in climatic temperatures melt sea ice, the US Geological Survey predicted that two-thirds of the polar bear population will die out by the year 2050. A dramatic decline in polar bears is already occurring in our lifetime, which, according to historical data, is but a very small fraction of the time these animals have roamed the vast seas of the Arctic. The main threat to the polar bears is the loss of their sea-ice habitat that is caused by global warming.…

    1 Dec. 2015. The scholarly article, “Polar Bears in a Warming Climate,” uses the scenarios predicted by climate change models to explore the progressing sea ice changes in the Artic and assess the changes that will lead to dramatic shifts in trophic interactions between polar bears and their main pray: seals. The article argues that all polar bears show behavioral plasticity but given the rapid pace of ecological change in the Arctic, the long generation time, and the highly specialized nature of polar bears, it is unlikely that polar bears will survive…

    Global Warming If you ever wanted to see polar bears in the wild, your time is running out. Global warming is causing polar bears, and many other species to go extinct. Global warming, also known as climate change, is the rising of the Earth’s temperature due to greenhouse gases, like carbon dioxide and nitrous oxide, getting trapped in the atmosphere. When the gases can not leave the atmosphere, they absorb radiation and sunlight from the sun and make the atmosphere warmer.…

    They have a thick layer of fat under their skin, which is surprisingly black. They have a dense undercoat helping insulate heat. “Each hair shaft is pigment-free and transparent with a hollow core that scatters and reflects visible light, much like what happens with ice and snow”(1). Although their fur appears to be white, it is actually transparent. Insulating heat is key to surviving the artic temperatures.…
