I don’t think this is a new idea. I recall learning about 50 years ago that Greenland cooled and the Norse culture became more ‘primitive’ (a relatively rare occurence) because the cooling and isolation left fewer resources available.

Wasn’t this already well established? I mean, I didn’t really know about the Saqqaq or the Dorset, but I thought it was already known that the Norse were essentially frozen off the island. There was archeological evidence that some perished amid miserable circumstances (cold and hunger).

As farmers the Norse Vikings were more vulnerable to lower temperatures. The Inuit survived the cold interval, though not on Greenland.

I read that fresh water influx caused by melting glaciers and icebergs caused a temperature increase in the oceans which ultimately shifted the global jet stream and weather patterns during this period. This phenomena along with increasing greenhouse gas is driving our current climate. Combine air pollution and particulate, ash from volcanic activity, reflecting and cooling affect from jet exhaust and its know wonder our climatologist have difficulty predicting weather forecast. its a crazy feedback loop

Certainly Climate changes naturally but almost as certainly humans influence that change. And even if we didn’t, we’d want to, wouldn’t we? We’ve tried to change everything else! But whatever, it looks like its time to invest in Greenland real estate!

AGW is just a new twist on an old religious scam.

Hey Goody,
FYI Greenland is the largest island in the world. It is 836,109 square miles in area.

And Yup, why not work on your vocabulary instead of asking others to dumb down.

“Climate change took away many good things in the past, and it is more rapid than ever before” but it will keep on happening – as it has happened many times before!

It may be within normal variability; BUT CO2 addition corresponds to changing the set point and that corresponds to an infinite gain of the system. And higher gain means more rapid and just plain more oscillation. Eventually the system will settle down to a new set point after about a dozen cycles which in this case would be about 100 years if nothing else changes.
CO2 climate change is FACT by VIRTUE of BEING PREDICTED LoooNG BEFORE any effects were noticed–in 1900 by the first Nobel Laureate in Chemistry. The ONLY question left is: IS THERE ENOUGH GLOBAL COOLING (compensatory and man-made) TO counteract the worst of the forecasted outcomes?

Um, the more climate science learns, the less credible claims like that become. As time goes on, the world will realize that climate is unstable, it has always been unstable. What we see today is within normal variability. Cheers.

Climate change has adversely effected everyone not only the vikings of GreenLand but whole world. It has a complex nature.. and calls for better understanding and knowledge to handle this issue.. Not only rising and falling of groups but several other factors are going to be dependent upon climatic changes in near future
