The Arctic's climate is changing, with a noticeable warming trend that is affecting polar bears. The region is experiencing the warmest air temperatures in four centuries.The introduction into the atmosphere of increasing quantities of carbon dioxide and other greenhouse gases.permafrost has declined, leaving polar-bear denning areas susceptible to destruction by forest fires in the summer. A warm spring might also lead to increased rainfall, which can cause dens to collapse.
I think that the quantities of carbon dioxide should be decreased so that polar bears wont be extinct so fast.Polar bears depend on a frozen platform from which to hunt seals, the mainstay of their diet. Without ice, the bears are unable to reach their prey. A shorter hunting season has already adversely affected the polar bears
My opinion for hunters is to hunt on snakes as they shed skins and its useful too
Because polar bears are a top predator in the Arctic, changes in their distribution or numbers could affect the entire Arctic ecosystem. There is little doubt that ice-dependent animals such as polar bears will be adversely affected by continued warming in the Arctic. It is therefore crucial that all factors which may affect the well-being of polar bears be carefully analyzed. Scientists believe that we have about 10 years before we reach the tipping point with global climate change—although it would take many years for changes reversing the warming trend to show.
