I'm also unaware of any polynyas that were as large as the area apparently covered by the ship in the 1921 article. not that it isn't possible. And I don't think we read the same 1921 article, it was rather on the gloom and doomey side to me.. I see the whole AGW mess as a bunch of people yammering with a shocking lack of confirmed data with real science having been applied honestly and consistently, and the "politically" based alarmists having created amd creating much more fear mongering about the future to get attention, funding or both (and some to keep their well paying jobs, and others to pretend that they're saving the world from eeeeeeeeeeevil) than the so-called deniers. It's not news if there is no horrific warming in the future, not unlike some of Trump's more outrageous assertions or frequently wrong facts... and yes, that was an intentional comparison. -g- Of course the Greenland farms were alive and well during the Medieval Warming Period, but Greenland is the closest area to the Arctic that's historically provable. I think it's damn near impossible not to posit a large severely melting Arctic under those conditions, and that blows Koan's assertion that it has never happened before into the weeds. I won't tell you my debating history or experience... -g- And thanks for the other kind words, I only infrequently play an a'hole on the internet these days and usually only with the arrogant or "I'm always right" pretenders.
