Since there is so much worry about the Arctic Sea Ice extent this time of year, it is always good to get some historical perspective. According to this study, our current low Arctic ice extents are not unprecedented.
From a press release of the Geological Survey of Norway:
Recent mapping of a number of raised beach ridges on the north coast of Greenland suggests that the ice cover in the Arctic Ocean was greatly reduced some 6000-7000 years ago. The Arctic Ocean may have been periodically ice free.
BEACH RIDGE: The scientists believe that this beach ridge in North Greenland formed by wave activity about 6000-7000 years ago. This implies that there was more open sea in this region than there is today. (Click the picture for a larger image) Photo: Astrid Lyså, NGU
The complete story follows.
PACK-ICE RIDGE: Pack-ice ridges form when drift ice is pressed onto the seashore piling up shore sediments that lie in its path. (Click for a larger image) Photo: Eiliv Larsen, NGU
”The climate in the northern regions has never been milder since the last Ice Age than it was about 6000-7000 years ago. We still don’t know whether the Arctic Ocean was completely ice free, but there was more open water in the area north of Greenland than there is today,” says Astrid Lyså, a geologist and researcher at the Geological Survey of Norway (NGU).

fyi
And so the grant money must continue...
And 500 years from now, we'll still be saying "Maybe"...still don't know"...
Manbearpig frowns upon your shenanigans.

The first immigrants to these inhospitable regions succumbed to the elements nearly 4000 years ago, when the climate became colder again. (Click for a larger image) Photo: Eiliv Larsen, NGU

And 125000 years ago a sea passage once divided Antarctica.

The Guardian sees this as a global warming warning sign but misses the obvious, that the previous interglacial was NATURALLY much warmer than this one.
The various tribes/nations in Siberia and Central Asia are known to have moved North and South with the changes in the climates. Sometimes it was perfect for grass, and sometimes less so.
Nearer the coasts ~ e.g. the Scandinavian Peninsula or Kamchatka and Korea, the changes were moderated by the ocean, but they still happened.
We can dig up their stuff and see when they lived there ~ and sometimes we can actually tell who they were.
The Turkish speaking tribes of Central Asia regularly went as far South as India and as far North as the Arctic ocean. The spans of time for these moves are enormous, but they kept the memories alive so when conditions were right they could go where they needed to go. Sometimes they took over India. Other times they didn't.
In Eastern Asia just North of India's Ganges watershed only one Turkish speaking tribe is known to have gone North to Siberia, then South to India, then back North, and so forth.
Other groups would move East or West to take advantage of better grazing lands. Yet more groups would move up and down the coastlines to hunt seal, or to fish.
Based on what people were doing in Asia it looks like the major cycles last a thousand years or so, with the smaller cycles lasting a few hundred years.
The anthropogenic global warming crowd seem to want the rest of us to believe that these cycles have stopped!
A climate warning from the deep ( a sea passage once divided Antarctica 125,000 years ago. )
See the updates.
Well you might think there is a HIDDEN AGENDA....
Oh and the crowd is up to their old censorship tricks....see this comment :

I just posted to Climate Progress more contrary, peer reviewed papers concerning historic Arctic ice melt and don’t even see the words “your comment is awaiting moderation” whereas previously I did. Now I’m getting:
“Error 503 Service Unavailable

This is how you know you are over the target. :o)
Ya might want to put some ice on that, Al. /Bubba accent

No one saw the explosion, because it’s stuck up his ass.
Al Gore, a portrait.
That would be because 6000 years ago was before the flood and there wasn't as much water on the planet in the form of ice or in any other form for that matter. There are better arguments against the climate-change idiots.
