Polar Bears

Anthropogenic Global Warming - Failed Predictions


The polar bear population has been the subject of many AGW predictions that the polar bears were doomed to extinction because of “Climate Change”, with emotional ploys by publishing photos of bears “stranded” on vanishing ice floes.






The following link gives an incredible list of quotes and comments on polar bear populations that are all over the map.

There does not seem to be any really carefully documented numbers.   It seems like there is fair agreement, among non-AGW sources that the polar bear population was around 5,000 during the 50’s, and 25,000 around 2008.  Numbers in excess of 30,000 seem to be the estimate in 2017.  A “typical” quote:


“Krauss, now a Houston-based correspondent for The Times, told me he couldn't recall the source of the 5,000 number, but said that he understood the number to be "widely accepted." Lomborg also emailed me a reference for another, different figure he said he'd discovered after the book's publication: A report from the Soviet Ministry of Agriculture's S.M. Uspensky, who surveyed nesting sites on a portion of Russian turf and extrapolated an Arctic-wide population of 5,000 to 8,000 in 1965.” http://pbsg. npolar.no/docs/Proc01_1965.pdf.

“Interior Secretary Dirk Kempthorne said at the department’s press conference that the polar bear population increased from ‘a low of about 12,000 in the late 1960s to approximately 25,000 today.’ But the size of the world’s polar bear population is subject to much debate.”


Reinforcing these numbers, from the IB Times:  IBTimes artivlcle Link


"The U.S. Fish and Wildlife Service estimates that the polar bear population is currently at 20,000 to 25,000 bears, up from as low as 5,000-10,000 bears in the 1950s and 1960s. A 2002 U.S. Geological Survey of wildlife in the Arctic Refuge Coastal Plain noted that the polar bear populations 'may now be near historic highs,'" it read.

We should revisit occasionally what the proper role of government is.   As the constitution was a good sense of direction, we need a core set of principles to add in order to deal with the future.


So many want to engineer society, remove risk, assist certain groups, rather than let individuals thrive and raise communities.  Why?


Is Democracy where we all "get it good and hard" or is it the best means to a free society?


Should we roll with the special interests, or make the government achieve its proper role, what is that role, and how to do this?


When do deficits and governments become too large?


Government is becoming more elitist while trying to sell corrections to problems it created, what makes this possible?

Currently as a society, we are having a most difficult time discussing political issues.  What is driving this?   And why a rebirth in political culture would be a good thing.


Market Economy

Are "markets" dead as some would conjecture? Or is free enterprise what got us here?


Economic Theories

At the heart of economics there are several possible economic schools of thought, the essence of these schools of thought and how they relate to our lives.
