Climate Change

With the summers getting increasingly warmer and warmer, one of the main concerns in the world right is climate change. And more specifically, Global Warming, a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. Not only influencing us humans, it is problematic to animals.

According to Scientific America, Federal wildlife officials called climate change the biggest threat to the survival of the polar bear and warned that without decisive action to combat global warming, the bears would almost certainly disappear from much of the Arctic.

“It cannot be overstated that the single most important action for the recovery of polar bears is to significantly reduce the present levels of global greenhouse gas emissions,” the officials wrote in a report released by the Fish and Wildlife Service.The report, called a conservation management plan, is required under the Endangered Species Act and outlines what must be done for a species to recover and avoid extinction. The polar bear was listed as threatened under the act in 2008.

“The sooner global warming and sea-ice loss are stopped, the better the long-term prognosis for the species,” they added.

Scott Bergen is a landscape ecologist with the New York-based Wildlife Conservation Society and a contributing author to U.S. Geological Survey studies released in 2007 that found two-thirds of the world’s polar bears could go extinct by 2050. He and other WCS staff are “almost elated” with the decision, he said.

Todd Atwood, a research wildlife biologist at the United States Geological Survey’s Alaska Science Center who was involved in crafting the plan, said: “We wanted a document that really clearly stated that climate change was, in fact, the primary threat to polar bears in the long term. At the same time, we also wanted folks on the ground and around the country to know that we still need to do what we can in the near and mid-term.”

In its report, which defines what recovery means and sets goals toward achieving it, the wildlife agency says the threat to polar bears will vary depending on the steps that are taken to reduce greenhouse-gas emissions and slow sea-ice loss. If prompt and very aggressive action is taken to keep the rise in global mean temperature below 2 degrees Celsius, the chance that polar bears recover will be greatly enhanced.

This chart shows the decline of Polar Bears, Ever since 1993 the number of Polar Bears have started to decrease and as stated in the paragraph above, Polar Bears are expected to be extinct by 2050.

The Topic: Global Warming is a gradual increase in temperature in the Earth’s Atmosphere. Affecting Humans and endangering animals

Who Global Warming Affects: the biggest threat to the survival of the polar bear

Actions to Solve this Problem: Important action for the recovery of polar bears is to significantly reduce the present levels of global greenhouse gas emissions. The Endangered Species Act and outlines what must be done for a species to recover and avoid extinction.

Benefits of Solving this Problem: The Polar Bears will still have a place to live and the ability to reproduce to carry on the existence of Polar Bears

Outlook of Polar Bears: U.S. Geological Survey studies released in 2007 that found two-thirds of the world’s polar bears could go extinct by 2050.

Make the Problem Known: People today do not know how bad the problem of Global Warmings are, so they should create a document that is able to be accessed by the public to address this problem

Revised Outline:

The Topic : Global Warming. Not only affecting humans, but animals too.

Who Global Warming Affects: Wildlife is most affected. Polar Bears is one of them

Actions to Solve this Problem: reduce the present levels of global greenhouse gas emissions. Endangered Species Act.

Benefits of Solving this Problem: Prolong the life of Polar Bears

Outlook of Polar Bears: They are expected to be two-thirds extinct by 2050.

Make the Problem Known: Create a document and present it to the public how Global Warming is affect the world today.
