Glowbull Warming Update

 

1. I bet polar bears could hunt reindeer and elk just fine if they had to. Or catch slamon in streams. Like every other creature that has ever lived, they’ll have to adapt or die out. Or interbreed: polar bears can cross breed with brown and grizzly bears. The breeding seasons are very similar and the territories overlap here and there.

   About the only thing anyone could do to preserve the species as they now are is to ban the hunting of them. Which would be the responsibility of Alaska, Canada, Greenland, Russia, Iceland, and maybe the Scandanavian countries; most of the bears don’t live in US territory.

2. Interesting ... that same site says that polar bears are only a little older than modern man; the species has only been around about 200-250,000 years.
   

   All DNA evidence, regardless of some areas of uncertainty, corroborate conclusions from the fossil record that the polar bear is a recently derived species and is undergoing rapid evolution.

   So are they only a temporary niche species? Does that give them more, or less, credence in the Save The Species lottery?

3. Another one of those inconvenient truths: at least in Canada the polar bear population is growing.

4. 1000 years ago it was much warmer than now. Warm enough for the Vikings to colonize Greenland. What did the polar bears do then? Hibernate until it got colder during the 16th century? Or maybe they just hadn’t ‘evolved’ yet as Drew suggests.

   Let’s move some polar bears to Antarctica. It’s getting colder there and there are plenty of penguins for them to eat.

5. So.  Let me get this straight.

   Polar Bears have been around for 200,000 - 250,000 years.  And in all that time, not once has humankind been required to make sure they survive, until now?

   I would hate to see all the Polar Bears (or Grizzlies, or Browns or Blacks or Gummis) die off.  But absent some very extreme occurances, I don’t think man is going to affect the outcome much one way or another.

6. I’m wondering why the GEOLOGICAL Service is even looking at polar bears - except to be certain the bears aren’t creeping up on the geo-members with an idea about having them for lunch.  And why are they making recommendations about the bears to anyone - except the Inuit who have the guns and the right to shoot the bears if necessary.

7. What these environazis just don’t understand is that life is tenacious and needs no help from us whatsoever. Also they never consider that 99.99% of the species that have ever lived were already extinct before humans were here and therefore species extinction its a NATURAL function of the earth. If species where no longer going extinct now THAT would be unnatural.

8. during which the health of three polar bear groups and their dependency on Arctic sea ice were examined using “new and traditional models.[Those same models that can’t predict weather next week, right? -FC]”

   Actually, those are the same models that can’t depict LAST WEEK’s weather.
