In the article “With Climate Change, Grizzly Bears May Hibernate Less”, the author, Sarah Zielinski, explains the potential effects of climate change on grizzly bears. Zielinski states that climate change could potential cause bears to hibernate less. She also says that this worries scientists because hibernation is a very important time for grizzly bears, it allows them to survive on small amounts of food, because they reduce the amount of energy they use by around 85 percent. In addition, this is the time when females give birth to their offspring. This combined with the hunting of these bears could have a huge effect on the population of them. Research was done by The Karine Pigeon of Laval University in Quebec to see when grizzly bears

In the editorial by Ron Judd titled “Why returning grizzlies to the North Cascades is the right thing to do” found on the Seattle Times’ website, Mr. Rudd states his case for the reintroduction of Grizzly bears into the North Cascade Mountains of Washington State. He makes the argument that fatal interactions between hikers and bears are not a valid argument against reintroduction because the rarity of these encounters and the rarity of aggressive bears. He also cites some of his personal experiences encountering these animals and both his own and their reaction. Mr. Rudd uses this information to paint a picture that the bears are not as dangerous as commonly believed, using as an example the presence of grizzly bears in Yellowstone National Park which sees many more visitors than the North Cascades. Another point that Rudd discusses is his belief that bears are an important part of the wilderness experience, he shares his feelings after one of those encounters: “With senses heightened off the charts, it was as if I had stopped observing the natural world, and for the first time, stepped all the way into it.

This essay will be discussing how bears prepare themselves for the hard times of their life and why. Once the winter months start to roll around food gets scarce and it is hard for them to eat so instead of staying awake and starve themselves, they hibernate. In order to prepare themselves for this difficult time of year, the bears must create a safe shelter, gain a few extra pounds, and drink almost three times the amount of water as usual. Black bears are located all throughout the United States and they all have different ways of preparation depending on their environment. (Reference.com)

As a consequence, these animals are now forced to spend more time on shore scavenging for food, often going without while awaiting new ice to form in the fall. There is also growing concern for polar bear cubs that are thought to be incapable of swimming the increasingly greater distances in open water between shrinking ice floes. As evidence, they offer the growing number of very young polar bear carcasses that they notice being washed up on shore. Many mother bears also appear to be dangerously thin and less able to fend for themselves and their young. This situation is quite noticeable among polar bears along the western shore of Hudson Bay, especially around the town of Churchill Manitoba, a location where polar bears traditionally spend the late months of fall foraging on shore awaiting the freeze-up, a freeze-up that now comes later each year.

Apart from the sea ice, the polar bears have very few alternatives left when the ice melts and when their access to the ringed seal prey disappears with their habitat. The charismatic arctic hunters cannot adjust and sustain themselves on another food source. If the devastating process of climate change continues, there wouldn’t be a thin sheet of ice left for these extraordinary animals to survive

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 bold idea to establish grizzly surrogate mothers is one of the strategies proposed to counteract this problem and ensure a long lasting population. Grizzly bears are genetically similar to polar bears but are different because they have adapted to survive in warmer conditions. This is one of the main reasons they are still seen more often today. If the population of polar bears were to drop drastically, then we would be forced to look at the grizzly mothers as one of our only options. The transplant of polar bear embryos into grizzlies is all it would take to keep the declining population at a steady and safe
