Mudcat quit last night while I was assembling my reply about bears...so:

"fact: the world's polar bear population has gone up dramatically since the Endangered Species Act was signed in 1972." ---from PDQ


PDQ... what you are doing is the age-old routine of repeating one mantra, and 'suggesting' that it covers all that needs to be said about the issue. You do not seem interested in any OTHER facts that may cast doubt on what you wish to believe.

read this: "http://dotearth.blogs.nytimes.com/2009/03/24/more-on-the-polar-bears-fate/

Here: I'll quote a small bit for you:
"Just because polar bear numbers might have increased in the previous three or four decades, we must not discount the evidence that they are now declining in some areas and are expected to soon decline in others."
...also
..."Dykstra (http://www.sej.org/pub/SEJournal_Excerpts_Su08.htm) thoroughly examined media accounts that supposedly provided evidence of growing populations, and did a nice job verifying that they have no scientifically established basis. You might wish to refer to that document."

also

"Regardless, population recoveries, where they have occurred, are irrelevant in light of the recent changes in the availability of sea ice for polar bears. Because polar bears are entirely dependent upon the sea ice for their survival, any observed and projected reductions in preferred sea ice habitats can only result in declines."

There's a LOT more about the details of the studies of bear populations and how they have changed for 200,000 years and why they DO change. Some of the 'studies' were very cursory, and due to the difficulty of following any large % of the bears, simply declaring that "bear populations are fine" is a prima facie example of the 'wishful thinking' I was referring to.

The real importance of ANY of the facts is their bearing (no pun intended) on the overall issue of climate change and what such change portends for the environment in general, as WE are the only life form on Earth which can study it, reflect on it and do anything about it. We need to get it right as best we can.
