Sea ice silly season: Wadhams spouts fake facts about polar bears of northern Greenland

As the seasonal minimum for Arctic sea ice approaches, the media get carried away by hyperbole. Tha’t been true since 2007. This year, other outlets will need to work hard to beat yesterday’s bit of nonsense from The Independent trying to out-do The Guardian: it not only includes false polar bear facts (from sea ice researcher Peter Wadhams) but leads with last year’s controversial SeaLegacy video of an emaciated polar bear. Sea ice silly season has truly begun.

Wadhams (described as “one of the UK’s leading sea ice scientists” although not a particularly respected one) was interviewed about the small area of open water that opened up over the last few days in northern Greenland (see NSIDC photo below), driven by offshore winds (not melt). This region is the eastern-most part of the area that is considered the “last holdout” for Arctic sea ice: an immense band of very thick (4-20m) multiyear ice that stretches across the Arctic Ocean shores of the Canadian Arctic Archipelago.

The open water is expected to last a few days at most but Wadhams was absolutely breathless with dire warnings of what this might mean for the future of polar bear in the region (about which he knows nothing), rhetoric ramped up even further by the news outlet with quotes from co-director of the Grantham Institute (London), Martin Siegert, and predictions on how low the sea ice minimum might be.

I think this is a truly spectacular example of the ignorance of scientists speaking outside their area of expertise used to mislead the public but decide for yourself.

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.
