Is this a skeptic board or a cheer-leading squad for anything that can be brought up against Sarah Palin? From the OP:
Okay, so let's see if
the cited article tells us who is right?
Gee, sounds like someone is grossly misinformed or intentionally misleading alright, and it's not Governor Palin.
Great skepticism here occasionally. Confirmation bias is also common. Strive to overcome it more often.
Thanks for the lesson dad... oh wait....
Maybe this time The Exquisite Admonisher would admit HE is in fact is wrong on a given subject? Alas, somehow I doubt it.
(speaking of cheer-leading, sis, boom, ba.... GoooooooooOOOO Republicans!).
Too funny.
Anyway, in fact the article is misleading on this point, in that they didn't present the whole story. The general consensus is that most poplar bear numbers are diminishing but the real story is not a simple point A to point B journey which is why people often get confused on the subject (you sir are forgiven, Palin is not because she is using bad information as a basis for public policy).
The numbers are hard to judge because, see..... polar bears.....
live on ice... that.....
is disappearing.. unless you happen to live on a fantasy planet where all satellite data are fabricated as a grand plot by the vast Left Wing Environmental Conspiracy.
Because the ice is disappearing more and more bears are showing up in new areas on land or miles out to sea, places not part of their normal habitat. That is causing some issues with reporting and calculating actual present day numbers.
Also there is a whole chunk of missing data, bear census from the 50's and 60's appears to be nothing but guess work.
The 70's bear hunting limitations DID have an effect, but remember that there was very little data from the 50's and 60's to go on so even the extent of this rebound contains a little guess work of it's own.
As numbers increase it seems safe for the layperson to assume that the population is fine but, here is the tricky part. What are
normal population levels?
Of course, if we limit hunting they will rebound but are they actually rebounding to natural population numbers or are they rebounding to a number that reflects new environmental conditions?
Tricky to judge so scientists have to look at the bear's past and present habitat, low and behold as stated above, the ice that is the key factor in bear hunting patterns and seal birthing is dwindling.
It doesn't take a rocket scientist to put two and two together here. Bear populations are effected by limited hunting opportunities as would any other creature on Earth while under decreased food supply. This is backed up by scientific evidence that the condition (weight, size, physical appearance, number of cubs born) of bears in multiple locations is diminishing which is a precursor to a larger die off of individuals.
In summation, actual numbers before the decline in sea ice are unknown. Bear population did recover after hunting restrictions but scientific findings point to the conclusion that the high water mark of the rebound population is not as high as the (admittedly unknown) high water mark before the loss of the polar bear's natural hunting environment.
Because the original population numbers are unclear we have to weigh other data, such as current bear condition, bear migrations, and natural habitat to make a best guess at this former high water mark. Calculating this data leads scientists to the strong belief that, factoring in the statistical blip from over hunting earlier in the last century, bear population is in fact diminishing from it's natural population levels.
As Dr. Andrew Derocher from Polar Bears International put it.....
Comparing declines caused by harvest followed by recovery from harvest controls to declines from loss of habitat and climate warming are apples and oranges. Ignorant people write ignorant things.

Again, I submit that Palin is either grossly misinformed or intentionally misleading.
