how are the polar bears doing (no question less ice is an issue)

He's selling a book for crying out loud.
Maybe he can get Drumpf to tweet about it like Drumpf did about LL Bean. Alex "There is a cult of ignorance in the United States, and there has always been.

so the numbers of polar bears is wrong? not from the figures I have seen elsewhere

It would mean something if he wrote in a peer reviewed journal.
He just has an agenda and wants to make a buck. Alex "There is a cult of ignorance in the United States, and there has always been.

peer reveiwed journals have issues if you disagree with dogma when it comes to some subjects

Dogma comes from people who *believe*. That's not science.

http://www.iucnredlist.org/details/22823/0 Our analyses highlight the potential for large reductions in the global Polar Bear population if sea-ice loss continues, which is forecast by climate models and other studies (IPCC 2013). Our analyses also highlight the large amount of uncertainty in statistical projections of Polar Bear abundance and the sensitivity of projections to plausible alternative assumptions. Across six scenarios that projected polar bear abundance three generations forward in time using the median and 95th percentile of estimated GL, the median probability of a reduction in the mean global population size greater than 30% was approximately 0.71 (range 0.20-0.95; see Table 4 in the attached Supporting Material). The median probability of a reduction greater than 50% was approximately 0.07 (range 0-0.35), and the probability of a reduction greater than 80% was negligible. The International Union for the Conservation of Nature Red List Guidelines suggests that assessors consider nearly the full range of uncertainty in potential outcomes, and adopt a precautionary but realistic attitude toward risk tolerance (Section 3.2.3, IUCN 2014). In light of the significant probability, across scenarios, of a reduction in mean global population size greater than 30%, and the relatively low probability of a reduction greater than 50%, we conclude that Polar Bears currently warrant listing as Vulnerable under criterion A3c (IUCN 2014). (Emphasis added.) It looks like the average life expectancy of a polar bear in the wild is 15-18 years, some have been tagged that lived into their early 30s. 3 generations into the future is decades away, just as the ice melting continues... HTH. Cheers, Scott. |
