I have to admit I’ve been thinking about polar bears and what confounding factors might be problematic in any research re population increase, decrease, or stability. The first thing I would need would be an operational definition of “increase.” This means a significant positive change from an accepted baseline number of polar bears in years past. Has this baseline number been established? How? Who did it? Has the research been repeated? Have the results been replicated? Have polar bear populations been running steady during the last century or so? What about the human population? Has it increased significantly?
I’ve read a few articles now and what I have read throws the polar bear problem straight into the middle of the AGW controversy. I honestly don’t know if the polar bear population is increasing. I’m not in polar bear country seeing and counting all the polar bears and comparing them to the polar bears I counted last year and the year before that and on back fifty or so years.
If AGW exists, I believe polar bears are in for the fight of their lives.
IF AGW exists. Or maybe even if it doesn’t exist. Maybe the number of polar bears will significantly decrease for a reason other than AGW.
To start with I found this article:
grist.org/article/will-polar-bears-go-extinct-by-2030-part-i/
“The point is that you cannot simply summarize the status of polar bears-the information lies in the individual populations. You cannot put the various time periods together into a simplistic overview. Sea ice is declining but again, it is not declining the same everywhere. Some small areas of multi-year ice may improve habitat for polar bears. This latter point, however, does not mean that the habitat in all areas will improve and the predictions are very clear that the primary habitat of polar bears is at risk.”
I don’t know the source. I don’t know if this can be trusted. One thing that struck me is that a government agency is conducting research and that throws up a red flag. I would need to see the research itself. I can probably make some sense of it if I can see it. Other than that, this article sounds good to me. But then an opposing article might sound good to me, too. I can see some potential problems with studies but I haven’t found the studies yet. If people are seeing more polar bears, well, that’s not a very good way to determine if the polar bear population is increasing. It could be because humans are encroaching on their territory (it’s for that reason that where I live we are seeing more black bears, along with deer, raccoons, and bobcats). It could be because the habitat that the polar bears live in is being destroyed due to AGW or due to something else.
I don’t know at this point but it’s making me think. What if AGW does exist? I probably am not going to be around counting polar bears fifty years from now. What if there is a problem? What if our children and grandchildren and great great grandchildren are the ones that have to deal with it?
I’m just sayin’ here. Nothing upsetting me, nothing confusing me at this point. This is a starting point for me. I hope you all respect that.
I like that photo that is shown with the article; it shows off that blue tongue very well.
BTW, if I didn’t mention it before, the Sierra Club is pro-abortion IMHO (and a representative refused to be pinned down on the club’s position when I challenged him/her several days ago in a thread on facebook). He/she blew me off completely. I’ve cut off my tiny bit of financial support and I’m returning their current request for more money from me, along with a note explaining why I will never send them one cent again, in their nice SASE which they kindly provided (thank you, Sierra Club

). The problems I run into re the environment sometimes overlap with the pro-life position and in cases like that I NEVER support any organization that is pro-abortion. Sierra Club is out. And if you know of any other environmental/political organizations that are pro-abortion (such as Amnesty International), please let me know. It sickens me to think that I helped to support an organization that supports the murder of our unborn. That is anti-environmentalism, anti-Catholic, and anti-God.
