Polar bears are born into the Arctic winter blind, hairless, and no bigger than a guinea pig. For three months while storms rage and temperatures fall below -40 F, the cubs stay snug and warm in their mothers’ dens. But if current trends continue, newborn cubs along Alaska’s northern coast may instead perish out in the cold.
A new study suggests that before the end of the century, mother polar bears in this region may no longer be able to find the deep snowbanks they need to dig dens. Megan Liu, a high school student.
"They need that habitat to give birth," said Liu. Their analysis indicates that "if we don't restrict our emissions, very soon, within the century, there's going to be an extended amount of time when there's no available denning habitat for the polar bears."
Scientists have long known that climate change is hurting polar bears, but most research has focused on the loss of their sea ice hunting grounds, said Steven Amstrup, who oversaw polar bear research in Alaska for the U.S. Geological Survey for 30 years and now serves as chief scientist for Polar Bears International. Polar bears catch seals at breathing holes in the ice, so when there’s not enough sea ice, they are at risk of starvation. More than a decade ago, Amstrup and his colleagues predicted that unmitigated climate change could reduce the world’s polar bear numbers by two-thirds by the middle of the century. More recently, images of gaunt, staggering polar bears thought to be starving due to sea ice declines have stirred pity among scientists and the public.
Now, it seems climate change may rob polar bears in Northern Alaska of their nurseries as well as their hunting grounds.

There is copious reason to debate the statements in this article. To dismiss it (or other similar) solely because you'll be dead when the effects manifest is just selfish.

Well that settles it, they’re all going to die.
Why n=bother with higher education. Straws have been banned due to a 9 year old kid’s science fair project and now this from a high school kid.
liberals are mindless idiots
Gheeze, who dreams up this $hit?
I remember when the misinformtion about the Alaskan pipeline and the caribou was spread about birthing calves. Polar bears den to keep warm. If the temperatures are higher, why do they need to den to keep warm? Same misconception. Another lie about “climate change.”

Climate change could make giving birth riskier for polar bears in northern Alaska
I bet there are some people who want to see a lower polar bear population as they are becoming a menace in places.
Put in five rows of sweet corn...
Is there anything that doesn’t kill polar bears? Big giant pussies.
The watermelons are much more red than they are green. They don’t want to save the planet. They want commie power. Power over us. Power to blow our brains out.
That was demonstrated when it was illegal to destroy a bald eagle egg but commendable to destroy a human one.
What polar bears and what ice?
It's a balance. There's currently 3.5% human caused cull rate. That's pretty high for a slow reproducing species. In the 1970's they were becoming locally extinct due to hunting.

Maybe this is your first time reading an article on climate hysteria or something. NOBODY here takes these endless fake but accurate stories seriously.
The climate has been changing for billions of years. I can’t do anything about it and I don’t care.
Climate change can also bring freezing rain instead of snow which according to the article could lead to the dens becoming unstable Death Traps when they collapse. Nothing like a little over the top climate hysteria in the name of science.
“...vile, disgusting, evil libtard scum are all for killing a human baby up to the time of birth...”
“up to the time of birth” is just for now. It will eventually evolve to killing anyone inconvenient. They already say as much.
Yeah, maybe Sue Aikens from Life Below Zero can lease me a couple of acres by Kavik camp.
Note to ask: Can I shoot any caribou that tries to eat the corn?
Who was alive in the 1970s to remember that? Who knows what actually happened?
With a two fer, I would take my position and go home quietly with full validation if I were a progessive.

First Greta Thunberg, and now her.
But wait. There is a silver lining in all this. Evidently we don’t need college science departments anymore. So shut them down, and save a ton of money. We can get all the scientific facts we need just by asking random high school students.
