The ice of Canadian arctic is melting, believed to have been caused by global warming. A researcher at the Colorado Center said that Canadian Arctic ice was melting at a far quicker rate than anticipated. The melting has caused coastal ice in parts of Canada to become quite brittle. That ice easily breaks away in large chunks and melts in the open ocean. It could affect shipping and overall sea levels as more icebergs calf into the sea. As ice has melted and floated into the open Ocean, The previous record sea level for Arctic sea was recorded on Aug. 15, 2005, though scientists said there was a high probability that the record would be breached in the near future. Also in the north provinces of Canada and other regions susceptible to spring flooding, changes in overall sea levels could result in increased frequency of ice flooding. Damages caused by these events have already cost Canadians an estimated $60 million annually.
Global Warming effect has serious consequences for all life-form, but it is of especially great concern for the polar bear. Polar bears around Canadian arctic may be among the first victims of global warming. As is melting the ice, the bears are losing their . Also the bears feeding season, for which they need ice flows to hunt and eat, has been shortened. Polar Bears will have a difficult time finding food. In fact, numerous polar bears are feeling the effects of a shortage of food and are facing starvation. The bears will be getting thinner, and fewer bears would be surviving. If the Canadian Arctic ice cap continues to melt sooner and form later, polar bears will become too thin to reproduce and they will become extinct by the end of this century.
To sum up the above issues, there are many things have been affected in the Canadian arctic cause by global warming. Which include the average temperature increase in the Canadian arctic, the ice glaciers melting, and the polar bears is hard to survive. Global warming is caused by human activity, and if we don’t have any solution to solve this issue, the impact from global warming would be worse and worse. Stopping global warming is very urgent, it is imperative to protect our earth now.

HOW GLOBAL WARMING IS AFFECTING THE CANADIAN ARCTIC
Recently, global warming has become a very hot issue, also the impact between global warming and Canada is fast becoming a popular topic. The Canadian Arctic has changed dramatically due to global warming, and this report will focus on the three major issues about how global warming is affecting the Canadian Arctic. The first issue in this report will discuss the average temperature increase in the Canadian Arctic. The second issue is about the melting of the ice glaciers and shelves. Finally, this report will discuss how global warming is affecting polar bears in the Canadian Arctic.
In recent years, global warming is actually affecting the temperature of Canadian Arctic. If there is one degree Celsius increased in the equator, there would be 12 degrees Celsius increased in the south and north poles. Canadian scientists discovered high average temperatures these years, with the Canadian Arctic being particularly hard hit by abnormal heat and declining ocean ice. Figure 1 shows the average temperature in Canadian Arctic has already up more than 1 degree Celsius throughout a span of 140 years, moreover, scientists expect the temperature in Canadian Arctic could potentially rise by as much as 5-10 degrees Celsius over the next century if we don’t have any methods to stop it. This warming could cause some serious problems for Canada. Increased temperatures, the panel says, will lead to sea-level rises and a likely increase in flooding. Therefore, that’s how global warming is affecting the average temperature increase in Canadian Arctic.
The ice of Canadian Arctic is melting, believed to have been caused by global warming. A researcher at the Colorado Center said that Canadian Arctic ice was melting at a far quicker rate than anticipated. The melting has caused coastal ice in parts of Canada to become quite brittle. That ice easily breaks away in large chunks and melts in the open ocean as shown in figure 2. It could affect shipping and overall sea levels as more icebergs calf into the sea. As ice has melted and floated into the open Ocean, the previous record of the highest sea level for Arctic sea was recorded on Aug. 15, 2005, though scientists said there was a high probability that the record would be broken in the near future. Also, the northern regions of Canada are susceptible to spring flooding; changes in overall sea levels could result in increased frequency of ice flooding. Damages caused by these events have already cost Canadians an estimated $60 million per annum.
Global warming effect has serious consequences for all life-form, but it is of especially great concern for polar bears. Polar bears around Canadian Arctic may be among the first victims of global warming. As leads to the melting of ice, polar bears are losing their . Also the bears feeding season, for which they need ice flows to hunt and eat, has been shortened. Polar Bears will have a difficult time finding food as shown figure 3. In fact, numerous polar bears are feeling the effects of a shortage of food and are facing starvation. Polar bears will become sick, and fewer polar bears would survive. If the Canadian Arctic ice cap continues to melt at as fast pace, polar bears will become too weak to reproduce and they will become endangered and possibly extinct by the end of this century.
To sum up the above issues, it has shown that global warming is affecting the Canadian Arctic in more than one way including the average temperature increase in the Canadian Arctic, the ice glaciers melting, and the polar bears having a hard time to survive. Global warming is caused by human activity, and if we don’t have any solution to solve this issue, the impact and consequences from global warming would be devastating. Stopping global warming is very urgent, it is imperative to protect our Earth now.
