Hudson Bay could be ice-free in winter within 5-10 years, says seal researcher

Ringed seal biologist Steven Ferguson, in a statement to a reporter from the Winnipeg Free Press, made one of the boldest predictions I’ve ever heard:

“Hudson Bay could experience its first free winter within 5-10 years.”

You heard it here, folks. It appears Ferguson thinks Hudson Bay was never ice-free in winter even during the Eemian Interglacial, when the Bering Sea was ice-free in winter – something that has not come close happening in recent years (Polyak et al. 2010:1769).

Sounds like a bit of ill-advised grandstanding to me.

Polar bears that didn’t die from recent sea ice loss will die in 35 yrs, say ‘sperts

Yesterday, the DailyMail (among others) was suckered into running virtually the same story The Guardian (among others) hyped last year about this time.

Using a science journal version of the 2015 IUCN Red List assessment report, polar bear data collectors and their fortune-teller colleagues have managed to get polar bears back in the news.

I wrote about this last year – it’s actually good news, although you wouldn’t know it from the headlines.

Let me paraphrase the ‘sperts:

“After 10 years of ice conditions we didn’t expect would happen until mid-century (a worst-case scenario we said would cause more than 30% of the world’s polar bears to die – except they didn’t), we have now determined (using a new model and a brand new definition of sea ice specific to polar bears) that by mid-century, there is only a 70% chance that 30% of polar bears will die.”

This is how they explain away all the bears that didn’t die as they should have when summer sea ice declined to about 5 mkm2 and below after 2006.
