Q1: so then, whats killing all the polar bears and causing the loss of polar bear habitats?
Q2: why don't you google "global warming threatens polar bears" and see the thousands of articles that pop up instead of staking your claim on one single paragraph in one single article?
There has been a huge increase in the polar bear population. 12,000 to 25,000 since 1960's. So that means the there's a problem? This is nothing more than a left leaning moron trying to find one more reason why we shouldn't be drilling for oil up there. Global warming and all of the Al Gore experts are scrambling because the "proof" of global change has been proven wrong. We're not seeing an increase in temperatures, we're seeing a drop. Even here, the temps are lower this year than last. Granted, it was still 118 F but it's cooler this year.
um, Bush's sec of the interior is hardly a "left leaning moron" as you'd like to think. he's the one who pushed for the re-classification of the polar bear.
In areas where long-term studies are available, populations are showing signs of stress due to shrinking sea ice. Canada's Hudson Bay polar bear population has dropped 22% since the early 80s.
global warming has been more than proven. we're now trying to determine humanity's role in the whole thing. you're way behind on that one obviuosly.
we're not seeing a drop in temps. you're just wrong. ocean temps have levelled after rising for many years. and they are expected to rise again.
and the fact remains that spring is beginning earlier worldwide and fall is beginning later. already proven.
and the arctic just had its hottest winter ever:

and I don't know where "here" is for you, but it sure ain't the west coast.
its HOT!
Ice shrinking? I was up in that region and there's tons of ice. Hudson Bay is seeing a decrease? Could it be that there are more homes and people there?
As to you load of bull on the warming, tell you what skippy, I still have a mountain of snow in my plants parking lot. Okay, it really doesn't look much like snow anymore but it's frozen stuff of some sort. Last year we had over 100" of the stuff. Over the last several years we've seen more snow, less heat and the like. Even your Sky is Falling preacher, Al Gore isn't calling it Global Warming, it's now being called Global Climate Change. In the Navy our weather people called them cycles. With over 100 years of weather patterns to compare, we're not seeing the terrible changes your team is claiming. I think it's a political move. New ice age when Ford was in. Acid Rain when Reagan was in. Now Warming when Bush was in. Funny how you didn't notice the problems when Dems were in. Too drunk or high?

so were the scientists. they have been this entire time. and by every measure, the ice is shrinking numbskull.
I stopped reading right there.
I've had a few hours of total boredom so I found a book on the polar bear and their habitats. Now this is an older book from the 70's but it was pretty clear they need lots of space. Other than during mating season, they have many miles between each other, they don't like crowds. That being said, with the 25K now out there, they're actually over populated.
On the warming, I've asked this before. The planet is around 4 billion years old. Your "expert" models are based upon a little more than 100 years of knowledge. That's less than even your most liberal margins of error. You don't have enough evidence to form a idea, theory or hypothesis much less than drawing a conclusion.
the experts' knowledge is based on 700,000 years of ice core samples, not simply 100 years of weather pattern knowledge.
do some more research and get back to me.
