Researchers have admitted that their estimates for populations of polar bears are " simply a qualified guess given to satisfy public demand."
There is only "rudimentary knowledge" at best to support the figures of the animals that have become a symbol for climate change alarmists.
Blogger Susan Crockford reports on Polar Bear Science
that she received an email on May 22 from Dag Vongraven, chairman of the IUCN Polar Bear Specialist Group [PBSG], that an upcoming report on worldwide polar bear population would contain a footnote that some polar bear populations are simply best-guess estimates.
"As part of past status reports, the PBSG has traditionally estimated a range for the total number of polar bears in the circumpolar Arctic. Since 2005, this range has been 20-25,000," the footnote reads.
"It is important to realize that this range never has been an estimate of total abundance in a scientific sense, but simply a qualified guess given to satisfy public demand. It is also important to note that even though we have scientifically valid estimates for a majority of the subpopulations, some are dated."
The note goes on to say here are no "abundance estimates" for bears in the Arctic Basin, East Greenland, and Russia.
"Consequently, there is either no, or only rudimentary, knowledge to support guesses about the possible abundance of polar bears in approximately half the areas they occupy. Thus, the range given for total global population should be viewed with great caution as it cannot be used to assess population trend over the long term."
Crockford was critical of the fact that the total global estimates were presented as being based on facts rather than guesses. She also criticized the group for hiding the estimates in a footnote, and sending a note for her to reveal the truth rather than being upfront in the main report.
"None of these 'global population estimates' (from 2001 onward) came anywhere close to being estimates of the actual world population size of polar bears [regardless of how scientifically inaccurate they might have been]," she wrote.
"Rather, they were estimates of only the subpopulations that Arctic biologists have tried to count."
The PBSG official's email does not specify why the public demanded a count of polar bear populations, but The Daily Caller notes
that polar bears were the first animal listed on the Endangered Species List because of the threat of global warming.
