Polar Bears And Global Warming Effects

Recent studies since the year 2004 on polar bears and global warming have shown an alarming increase of polar bear drowning. Since polar bears are basically good swimmers, researchers were puzzled how and why they drowned.

Investigations soon showed that the combination of fewer and smaller ice floes and erratic climate changes have contributed to this situation.

The main cause of global warming is said to be emissions from burning fossil fuels. Although this is not the only cause for global warming, it is one of the main causes of temperature change.

The increase in the temperature of the air near the Earth’s surface (land and oceans) has effectively started melting the polar ice caps. In addition to eventually leading to a rise in sea level, this melting affects the ice shelves and ice floes – the habitat of polar bears.

Polar Bears Must Hunt for Food

The result of melting ice caps means that polar bears and global warming is a fatal combination – because many bears are now drowning due to lack of ice floes to hunt and den on.

Other devastating effects are that bears are being reduced to hunting less on ice floes and instead venturing closer to humans.

The creatures’ usual staple of seals may dwell further out in the ocean. This means a more strenuous hunting journey with ice floes being fewer and farther between. To avoid straying so far from home, polar bears are being forced to scavenge around carcasses of animals killed by humans.

“What do polar bears and global warming have to do with me?” you might ask. And I would answer, “Quite a lot.”

Maybe more than you could guess.

Polar bears live, hunt, and den on sea ice

Polar bears are among the first large species to have been directly affected by global warming. You don’t have to think real hard to conclude that we will soon follow in the polar bears footsteps if we don’t take action soon to slow down climate change.

The majority of the world’s climate scientists agree – we need to solve global warming. . . starting NOW! Scientists at the U.S.Geological Survey say two-thirds of polar bears could die off within the next 50 years. Arctic and Antarctic species such as walruses, seals and penguins could soon find themselves on the same precarious path to extinction.

Treasured species like the polar bear and the grizzly won’t survive unless we take the needed steps to solve global warming right now.

For the sake of the polar bear, and other species and wildlands affected by global warming, we can’t wait any longer – America needs an energy policy now that helps solve global warming by investing in clean energy solutions.
