Ron Bailey reflexively jumps to the defence of Bjorn Lomborg:
Begley cites three examples from Friel about Lomborg’s errors, e.g., polar bear population trends and climate change, human deaths from heat versus cold, and the implications of Antarctic ice shelf disintegration. You can read Begley’s reporting and judge for yourself. (With regard to polar bears, let’s assume that Begley’s reporting of Friel’s analysis is accurate and that Lomborg’s sourcing is, how should one put it, thin and misleading. However, I do note in passing that a 2009 review article in the journal Environmental Reviews cited literature that found that only four of 13 Canadian polar bear subpopulations were declining, four were stable, three were increasing, and two were unknown. Canada is home to about 60 percent of the world’s polar bears. Since Cool It was published in 2007, Lomborg couldn’t cite this literature, but Begley could have.)
Since Friel checked Lomborg’s references, it is only appropriate to check Bailey’s. The literature Bailey refers to is the report from the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). Here is what the review article says about the conclusions of that report:
Based on the best available information, COSEWIC concluded
that polar bear was a species at risk in Canada, formally
advising the federal government of its assessment of
special concern in August 2008. COSEWIC identified the
primary threats facing polar bear to be: (1) reduction in sea
ice, caused by climate change, particularly for subpopulations
in the southern part of the species’ range; (2) overhunting
for subpopulations shared by Canada and Greenland;
and (3) habitat threats from industrial development. Inuit
have also observed deteriorated ice conditions in some
areas (e.g., reduction in multi-year ice, fewer icebergs, thinner
ice, earlier ice break-up) and have expressed concerns
about the consequences that changes in sea ice may have on
polar bears (Atatahak and Banci 2001; Dowsley 2005; Keith
et al. 2005; NTI 2005). While assessing polar bear as a single
unit throughout its range, COSEWIC made it clear that
some subpopulations of polar bear, such as those in the
Southern Beaufort Sea, Western Hudson Bay and Baffin
Bay, faced very high probabilities of decline.
Yes, that’s right, Bailey has done a Lomborg — his reference says the opposite of what he implies. Of course Bailey was Lomborging references even before Lomborg started doing it. Here he is doing it in 1993.
