When Bill Clinton took office in 1993, global warming was a slow-moving environmental problem that was easy to ignore.

Watch Live: Polar Bears Wait for Ice to Form at Hudson Bay

Amstrup, who has studied polar bears in Alaska for the past 30 years, said the bears have been forced to stay on land about one day longer each year. Because of annual variation in the climate, however, scientists don't know exactly how long the Hudson Bay bears will have to wait for ice to form this year. For the next few weeks, Amstrup and his team are at Hudson Bay, observing the bears from all-terrain vehicles called Tundra Buggies.

Most of the time, the bears are just loafing around and resting. Because they're not hunting, they must conserve energy. However, some of the young male bears will play-fight with each other. The sparring behavior allows bears to assess each other's physical strength at a time when they aren't competing for food or prospective mates, Amstrup told LiveScience.

But as earlier ice melts drive the bears ashore earlier, when they've had less time to hunt and bulk up, "we will probably see less and less sparring behavior," Amstrup said. "Here in Hudson Bay, we've seen declines in the weight of the bears," he said, adding that leaner females produce fewer, smaller cubs, which don't survive as well.

Viewers might catch a glimpse of mothers with their cubs. But what they won't see are pregnant mothers, which have all moved inland to den, said wildlife biologist Tom Smith of Brigham Young University in Provo, Utah. The mother bears have their cubs in January, and emerge from their dens in March.

Though not at aggressive as grizzly bears, polar bears do kill each other from time to time. "The single most consistent threat to cubs is other bears," Smith told LiveScience. Bigger bears might kill the cubs because getting rid of them will bring a mother bear back into heat, making her fertile again, Smith said. Or they might simply kill the cubs for food.

"Cannibalism in bears is documented many times and many places," Smith said, adding, "It's definitely not the Disney version of things."

Still, the risk of a reprisal from a bear fighting back does deter them from attacking. And in general, they are fairly social animals, Smith said.

The webcams were initially developed to attract public interest in the bears. Users can also take snapshots from the video and share them using social media. Now, scientists are discussing the potential for citizen science. For instance, snapshots could be used to track the bears' weight over time, Amstrup said.

Ultimately, the webcam's most important value is "to get people's attention focused on the plight of the polar bears," Amstrup said. "They're emblematic of the future we all face, if we don't take action against climate change."

Team Green is always warning and threatening; they induce fear to achieve their political schemes.
Who won the election?

You are always warning and threatening of dire consequences of reducing GHG output; pretty much baseless claims. You fear the new and the progressive, a scaredy-cat comfortable with what's old and known.

In addition, you're an idiot. This is where we differ.

Just look at the asian nations. they are pumping out Co2 emissions like crazy and they dont give a shit..yea your black hope is really helping the world on this one..your just another fucktard lib...”
From Clay Center, KY:
“you liberal pieces of shit can take your crap somewhere else....
another fun fact for you is that Obama "your savior" has spent more than bush did in 8 years already....oh gosh facts sure hurt dont they.....again prove me wrong with a link to a credible news source that reports otherwise...in detail please....
its obamas admin now and its time to quit blaming Bush for things Obama has done....wake up and smell the coffee....
please tell me how we are better off now than when Bush was in office....how does the fed printing 80 billion a month helping the AMERICAN DOLLAR?? yea that FAKE money has the market so inflated its funny....please tell me how Obamacare is cutting costs of medical expenses and why corporations are now making people part time to keep from paying the ADDED ins costs??......in detail please....”
From Belfry, KY:
“China is burning more than any other country without evironmental protection agency laws. So what's the difference? There economy is thriving while americas going under!”
I see, you, like a teenager use the argument that because like others are doing it, like it is ok for you to do it.

If the economy hadn't crashed, we could have spent all that money on things that would have helped our infrastructure, our environment and our health care system.

BTW, companies already had cut hours for workers because of the high cost of health care. If the private insurance is so good, why is the cost so high? Why is our health care system the most costly one in the industrial world? We need a single payer insurance system. That will never happen as long as the insurance corporations are able to buy politicians!

The Earth is warming. CO2 is a greenhouse gas that traps discrete IR radiation in the atmosphere. Burning fossil fuels increases the CO2 in the atmosphere. Those are facts.

But, toxic topix AGW deniers have to plagiarize educated people now. With the election showing tea partiers fading into political history, toxic topix tots have no one to copy on their own side of issues.
I wish I where educated, but seeing as mom dropped me on my head when I was a child and I rode the short bus, I make it a habit of pretending Im smart.

It's just about money. both sides. we have thorium. reactars built 50 yrs ago. safe clean & enough power to last longer than the earth will be habitable. but TOO cheap. I don't know how many of you stand to gain from this drivel or how many are being led around by the nose, but both sides are full of shit. btw, the greatest greenhouse gas is water vapor, so all this debate about CO2 is full of shit too. Damnit when are you people going to get your heads out of your asses?

Seeing as how your ISP address is California, and not Snohomish, WA, we can tell that you are not really litesong, so that what you say is most likely true, even though your usual behavior is lying.

You wish you were litesong. Imitation is the sincerest form of flattery.

Recent research shows that Arctic sea ice is melting faster than expected. As the Earth continues to warm and Arctic sea ice melts, the influx of freshwater from the melting ice is making seawater at high latitudes less dense. In fact, data shows that the North Atlantic has become fresher over the past several decades. The less dense water will not be able to sink and circulate through the deep ocean as it does currently. This will disrupt or stop the Global Ocean Conveyor. Scientists estimate that, given the current rate of change, the Global Ocean Conveyor may slow or stop within the next few decades.

What is causing the melting? Global warming, of course. If this turns out to be the scenaero, then the warming is still not a good thing.

"This would not be the first time that the Global Ocean Conveyor was halted. There is evidence from sedimentary rocks and ice cores that it has shut down several times in the past and those shut downs have caused changes in climate. One of the most well-known, the Younger Dryas Event, happened about 12,700 years ago and caused temperatures to cool about 5 C in the region."

Hmmm... "not the first time". Another self-contradicting post.

But maybe it was those stone ages SUV's?

Ok then what do we do. China gets 85% of its energy from burning coal, try to use nuclear now look at the pacific ocean its so polluted we will be seeing the efects from that for decades to come, and the gulf of mexico same scenario polluted the earth will win weather we like it or not but we wanted technology and cars and jets and ships and semis to deliver all the garbage us humans "need" to have a happy life. Seems like a downward spiral and we are out of control
