Statement of polar bear population size estimates by polar bear scientists in 1965

Polar bear scientists in 1965 published a consensus statement on population size, with no caveats that these were ‘wild guesses’ or not to be taken seriously. They quoted some of the same authorities that I did when I suggested a plausible baseline figure. Andrew Derocher, Steven Amstrup and others who say there has never been population estimates for the 1960 or 1970s are not defending science, they are lying to protect their ‘polar bears are all gonna die because of climate change’ narrative. No other biologists do this, even those who insist the species they study are at risk from human-caused global warming. You should ask why.

This controversy is why archives like the one I created yesterday are so important: they make it impossible to re-write history as some insist on doing:

The slaughter of polar bears that rarely gets mentioned (ca. 1890-1930)

Chock this post up as another example of mind-blowing information you sometimes find while looking for something else.

In their dendrochronology paper on trees associated with polar bear dens in western Hudson Bay, Scott and Stirling (2002:157) reference an MA thesis in Geography by James Honderich (1991), in regards to a discussion of denning frequency during the period 1850-1899, “when polar bear hides were more or less traded consistently.”

It turns out the James Honderich’s thesis is actually a summary of polar bear harvests in Canada from about 4,000 years ago to 1935. The number of polar bears taken by Arctic explorers (1594 to mid-1900s), Hudson’s Bay Company fur traders (from 1670 to 1935) and Arctic whalers (1820s-1935) were calculated from a variety of historical sources. This post is a summary of the results for the period 1800-1935. It is likely you have never seen this astonishing information before and the implications for polar bear biology are substantial.
