Good times:

Polar bears are starving and could face extinction faster than previously thought, according to a new study.

Published Thursday in the journal Science, the study was conducted by researchers who fixed collars on nine bears and recorded their activity levels for up to 11 days. They found that the Arctic creatures were suffering an extreme shortage of food.

As a result of climate change, the sea ice in the Arctic is melting and forcing the bears to travel further and use more energy to catch their prey.

The three-year study conducted by the US Geological Survey and University of California, Santa Cruz, found that the Arctic predators are moving 1.6 times more than previous studies have reported. That increased movement in the search for food leaves them shorter on the calories they need.

“The purpose was to get a better understanding of what the changes in sea levels are and how they are impacting the polar bears,” Anthony Pagano, a lead researcher in the study, told CNN.

Polar bears have been listed as endangered species by the US Fish and Wildlife Service, and the protection program repeatedly emphasizes the importance of climate change.

“Without decisive action to address Arctic warming, the long-term fate of this species is uncertain,” Greg Siekaniec, Alaska regional director of the wildlife agency, told CNN last year.
Arctic sea ice in December was at its second-lowest level since 1979, according to the National Snow & Ice Data Center.

USGS researchers’ most recent estimate of the polar bear population indicates their numbers have declined by 40% over the past decade, but a common problem for researchers is that it has been difficult to study polar bear behavior in these harsh environments, Pagano said in a statement.

“We now have the technology to learn how they are moving on the ice, their activity patterns and their energy needs, so we can better understand the implications of these changes we are seeing in the sea ice,” he said.

Of course, we don’t have technology to stop all of our other technology causing global warming. Well, at least they might have idiots to eat for awhile.
