Arctic shrinkage

The polar bear is an animal that you can find in the bitter Arctic region. The Arctic is located at the northernmost part of the Earth. The Arctic is basically covered in water and most is frozen. Some features that can be found in the water are icebergs and glaciers that are made of frozen freshwater. A fact about glaciers and icebergs is that they make up 20% of Earth’s supply of freshwater. Most of all the Arctic ocean is made of sea ice which is frozen seawater that often is covered with a…

Canada has the right to assert arctic sovereignty for the surrounding areas and has the right to claim the Arctic, however not only does Canada benefit it the most it's what makes sense through enforced jurastristion Canada understands the needs for the Arctic as well as having a stable government. The northwest passage, however, interferes with who actually has access to the Arctic making it almost a war. Most commonly power is divided and shared amongst the territories surrounding as long as…

kingdom of narwhals is animalia. The phylum for dolphins is chordata the class of narwhal is mammalia. The geographic location for narwhal is in Greenland, Canada, Russia, and the Arctic Ocean. The biome where you can find narwhals is on the surface of the Arctic Ocean. Narwhals live in the icy waters of the the Arctic seas. In the winter, the narwhals go deep in water beneath the ice pack in groups of 5 to 10. In the summer, they migrate to shallow, ice free summer grounds where they gather…

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…

Many people think polar bears and black bears are the same but that is not true. Polar bears and black bears have many differences and some similarities. A polar bears weight is about 330 to 1500 pounds and a black bear can weigh 90 to 600 pounds. Their height is also different, a polar bear can be from 7 to 8.4 feet and a black bear can be 5 to 6 feet. Polar bears are found in circumpolar north in areas where they hunt their prey and black bears live in North America in the forest. Polar bears…

Ever since I was four years old, I have read books watched movies, and have heard out the breathtaking experiences in Alaska. Though I haven't been there, I know everything there is to know about this astonishing state. Polar bears and penguins, are some of the many animals I would dies to study and see up close. Their behavior and adaptations are unlike anything ever seen in this common state we know as home. The climate is like no other, except maybe Antarctica, the snow and ice surrounding…

Sea Levels Rising Hurting Our Animals Polar bears are on the threatened species list because of global warming and sea levels rising. Millions of species aquatic and land animals are dying. Most under the sea ecosystems are severely affected by global warming which causes sea levels rising. For example, mangrove ecosystems require constant sea levels to survive. Sea levels are rising and affecting polar bears, sea turtles, and coral reefs. Polar bears are in jeopardy, becoming extinct…

live on is melting due to global warming. The population will continue to drop so long as we don’t do anything about it, and soon, no one will get to see the snow white bear. In 2012, about 1.32 million square miles, which is right around 24%, of the Arctic Ocean was froze over. That is low considering that it dropped about 3% since 2007. The heat will continue to increase causing the ice to melt completely. What would happen if all the ice would melt? First, as the ice melted, the sea levels…

mainly ringed and bearded seals located on the border of the Canadian arctic. Those seals are killed by polar bears during breathing holes depending on the availability of seals in the ecological niche (Stirling and Archibald 1977). However, arctic foxes and polar bears compete for the adults’ seals and the competition for food increase between them. It is not clear whether the polar bears feed with seals or are hunt by arctic foxes. If seals are not available, polar bears feed…

According to the 2014 Arctic Report Card, there have been significant changes in sea ice extent. Specifically, the report addresses the slow but significant seasonal decline in sea ice cover. Arctic sea ice is of utmost importance for ecosystems to thrive. Post et al. (2013) discuss this further, stating “the sea-ice biome influences the abundance, distribution, seasonality, and interactions of marine and terrestrial species.” This is especially true for polar bear populations in the Arctic, as…
