William Patterson, from the University of Saskatchewan in Canada, and his colleagues have shown that switching off the North Atlantic circulation can force the Northern hemisphere into a mini 'ice age' in a matter of months. Previous work has indicated that this process would take tens of years.
Around 12,800 years ago the northern hemisphere was hit by a mini ice-age, known by scientists as the Younger Dryas, and nicknamed the 'Big Freeze', which lasted around 1300 years. Geological evidence shows that the Big Freeze was brought about by a sudden influx of freshwater, when the glacial Lake Agassiz in North America burst its banks and poured into the North Atlantic and Arctic Oceans. This vast pulse, a greater volume than all of North America's Great Lakes combined, diluted the North Atlantic conveyor belt and brought it to a halt.
Without the warming influence of this ocean circulation temperatures across the Northern hemisphere plummeted, ice sheets grew and human civilisation fell apart.

So then we really should do something about Global Warming.
Specifically, we should tape Al Gore’s mouth shut before the bile flowing from it reaches the Atlantic and dilutes the North Atlantic conveyor belt causing a mini ice age.
There is nothing like Lake Agassiz today so I’m not too worried. No chance Greenland will melt in one day.

Well there is only one thing to do...we must all buy SUVs and warm the planet.
Like all climate change, this was probably man made. No doubt someone pulled his finger out of the dike.
At George Bush’s order.
I have a fear of the climate, and that fear is that in the move to reverse “globul warming” scientists will purposely upset the balance by injecting substances into the atmosphere, placing “blankets” on ice, and unknown other things triggering extreme cooling. If they can trigger a couple of volcanos, it would probably be enough to destroy crops for several years, causing massive starvation. MAN, in his ultimate wisdom, is a babbling idiot, God save us from ourselves.
God save us from ourselves.
...please happen during the Copenhagen climate change summmit!
Um, not to be picky, but exactly how much "civilization" could we be talking about here? This happened almost 13,000 years ago.
I mean, this is hardly the ransacking of the Alexandria Library.
You ain't alone in that one. I figured that all it would take is some rich idiot that "Means Well" and "Needs to do SOMETHING" to really screw things up.
I think that the worst of that danger is past, enough people are getting a clue....for now. We'll see what comes down the pike next generation.
I’ve heard if the gulf stream slows down or stops, Europe with look alot more like Siberia!
Unearthing a Cold SnapNow a team of scientists, writing in the journal Nature, estimate that more than 100 trillion cubic meters of cold, fresh water -- more than the current volume of the five Great Lakes -- was released into the Labrador Sea when the ice dams, remnants of the Laurentide Ice Sheet that covered much of northeastern North America during the last Ice Age, melted about 8,200 years ago. Average temperatures in Western Europe fell by about 6 degrees Fahrenheit, while Greenland suffered a 15-degree drop. And this wasn't just a brief climatic event: it persisted for two to four centuries. They say that flooding caused by the melting of ice dams in two huge glacial lakes in the Hudson Bay region disrupted ocean currents that contribute to atmospheric warming in Europe. Evidence for the flooding includes sediments that once underlaid the glacial lakes that were found 800 miles away, carried by the water (which probably flowed for a year as the lakes drained).

"Sensational" Archaeological FindThe Polar ice cap during the last Ice Age might not have been as extensive as previously thought, according to archaeologists looking at the remains of human settlements in the north of Sweden.

People may have lived in the northern region of Tornedalen as far back as 11,000 years ago, according to Olof Ostlund, speaking to the Norrlandska Socialdemokraten newspaper.
The 2 settlements were found in the area around Kaunisvaara, where a new mine is about to be built. Carbon dating of the finds show that they are much older than previously thought, and mean that previous theories that the area would be covered by the huge polar ice cap are wrong.
"We will now have to re-think our theories on how people migrated to northern Sweden and northern Norway. They didn't get here from the south via the coasts, the finds in Kaunisvaara make this very clear", Ostlund told the newspaper.Swedish archaeologists celebrate ancient findPeople lived in the Torne River Valley on the border with Sweden and Finland some 11,000 years ago... The settlement, found near Pajala in the far north of Sweden, are the oldest known find in the county of Norrbotten, according to the archaeologist Olof Ostlund. The find was uncovered when archaeologists were searching for ancient remains in the area around Kaunisvaar near Pajala where a new mine is set to open, according to a report in local newspaper Norrländska Socialdemokraten.

"Now the pages in the National Encyclopaedia regarding inland ice can be torn out and burned," Ostlund told the newspaper...
"I had been expecting old dates. But when I saw that the first numbers were very high I felt immediately that this was bingo. When the second number was five figures - I felt faint," Ostlund explained to news agency TT.
He was surprised that the find was so old and compared it to another settlement located nearby in Kangofors five years ago. That settlement had been used 10,000 years ago...
Ostlund compared the new discovery to the find in Voullerim in the middle of the 1980s of 6,000 year-old stone age shelters. Then the assumptions regarding the history of the pre-history of Norrland were revalued to take into account that people had actually lived there.

“exactly how much “civilization” could we be talking about here?
We don’t exactly know. A lot of it was on the coasts, which are now under under water.
There may have been a lot going on in the areas not covered by ice.
“Five kilometres off the south-east coast of India, submerged at a depth of 23 metres beneath the murky, shark-infested Waters of the Bay of Bengal, an ancient man-made structure sits on the bottom of the sea.
The structure is U-shaped, like a huge horseshoe; its periphery measures 85 metres and its walls are about 1 metre thick and 2 metres high.”
The draining of big, ancient fresh water lakes created a lot of different features on this planet.
