Twelve polar bear researchers, including Professor Andrew Derocher of the University of Alberta, are contacting governments around the world about the fact that one unexpected jump in Arctic warming could bring about a large decline of the world's polar bear population. "Earlier studies by Derocher and his colleagues show that one very bad ice year could leave hundreds of Hudson Bay polar bears stranded on land for an extended period. Derocher noted 'Such an event could erase half of a population in a single year.'" This quote highlights the extreme danger that polar bears are in.
NOS Themes
Science is based on evidence: In the article it states, "The effects of climate change on polar bears are clear from both observational and modeling studies in many parts of the distribution." This quote illustrates that there have been many observational and modeling studies to collect evidence.
Role of motivation and curiosity: This writer is not only writing; they are trying to convey the importance and urgency of polar bear safety. They are motivated, and are trying to motivate others to become involved in the conservation of polar bears.

According to an article from Polar Bears International, the polar bear population appears to be shrinking as it is listed on endangered species lists around the world. But there is also good news. Polar bears are being observed more and more on land, especially in Canada. Researchers still do not know if this is because they are being forced south due to loss of habitat, or if the population is actually growing. However, Polar Bears International still believes it is in the bears best interest to reduce our carbon footprint and save as much of the polar bears' current habitat as possible.
