The majority of our infrequent embargo violations are accidental and typically the result of mislabeled copy that does not properly list the 3 p.m. EST Monday embargo expiration. We have a separate situation with the Sunday Times of London. With EurekAlert, we have prevented their editors and reporters from accessing the embargoed news section of EurekAlert, which is where pre-print copies of our articles are accessible. …
At this time, we have no plans to remove the restriction we have placed on the editors and reporters from the Sunday Times. …
With the exception of the Sunday Times, we have not had any three-time repeat offenders. In the case of the Times, we have removed all reporters and editors from accessing our media materials.
It seems that you can’t trust Leake about anything.
In his story, Leake writes:
It means polar bears have already survived a global warming that affected the northern hemisphere from 130,000 to 115,000 years ago, when the Greenland ice sheet and the Arctic ice cap were smaller than now.
But omits to mention this result from the PNAS paper (my emphasis)
Even more surprising, the age of the modern polar bear crown group (the
clade containing the last common ancestor of all extant members) is
estimated to be less than 45 ky, slightly older than the age of the
ABC bears (Fig. 3A), a date that is also found with the expanded
dataset of control-region sequence fragments (Fig. S5). These
estimates suggest a very recent and rapid expansion of modern
polar bear populations throughout the Arctic since the Late
Pleistocene, perhaps following a climate-related population bottleneck,
although data from more modern and Holocene polar bear
specimens will be required to establish this.
