The US Geological Survey just released a report this week “warning a third of the world’s polar bears could be in imminent danger from greenhouse gas emissions as soon as 2025…Greenhouse gases are blamed for the climate warming that’s reducing the polar bear’s summer sea ice habitat”. This revised model then added the issue of harmful greenhouse gas emission where one of the scenarios predicted that global warming will stabilize by mid-century whereas the other shows that there will be prolonged emission affection the population of polar bear, resulting in a substantial decline by the year 2050.
Rebecca Noblin, from the Center for Biological Diversity, said that while there are other steps that could slow down the decline of polar bears, the only means of saving these animals in the Arctic is to reduce the emission of greenhouse gas. Studies have indicated towards survival threats being faced by polar bears due to fast melting of their natural habitat. Because of the change in climate, continuous rise in temperature and melting of the ice, they are forced to return on land in order to find food.
In response to polar bears being on land, a study earlier this year found the land-based food would not help a polar bear adapt to the loss of sea ice.
Researchers have discovered that polar bears are highly threatened by global warming after closely analyzing the situation.
The U. S. Fish & Wildlife Service (FWS) stressed in a draft recovery plan that a decisive action to address Arctic warming is necessary for polar-bear conservation. Close to half of the polar bear population lives in Canada. The scientists could not estimate an exact number of how many polar bear will be affected, but believe it while be a large part of the population. “Until that happens, we’re going to do everything within our power to give the polar bear a chance to survive”.
In addition, Secretary of State John Kerry pointed out that right now nations need to dramatically cut down Carbon dioxide emissions-particularly of black carbon and methane – since short-lived greenhouse gases could be an especially potent cause of Arctic warming. The plan will also include a better management of the bears’ food stocks, and better ways of preventing conflicts with humans and keeping bears safe from unsafe oil spills. He goes on to say, “These pollutants are a threat to everybody”. Polar bears are dependent on the ice for feeding, mating and producing offspring.
But the federal agency explained that saving bears can not be done by one state alone. Team members have expertise in polar bear biology, climate science, policy, communications, and traditional and contemporary indigenous ecological knowledge.
