Last Ice Age took just SIX months to arrive

It took just six months for a warm and sunny Europe to be engulfed in ice, according to new research.

Previous studies have suggested the arrival of the last Ice Age nearly 13,000 years ago took about a decade - but now scientists believe the process was up to 20 times as fast.

In scenes reminiscent of the Hollywood blockbuster The day After Tomorrow, the Northern Hemisphere was frozen by a sudden slowdown of the Gulf Stream, which allowed ice to spread hundreds of miles southwards from the Arctic.

Geological sciences professor William Patterson, who led the research, said: 'It would have been very sudden for those alive at the time. It would be the equivalent of taking Britain and moving it to the Arctic over the space of a few months.'

The subsequent mini Ice Age lasted for 1,300 years and was probably caused by the sudden emptying of Lake Agassiz in Canada, which burst its banks and poured freezing freshwater into the North Atlantic and Arctic Oceans.

That would have disrupted the Gulf Stream - the flows of which depend on variations in saline levels and temperature - and allowed the ice to take hold.

Some scientists believe that if the Greenland ice cap melts it could disrupt the world's ocean currents and have a similarly dramatic effect.

Professor Patterson's findings emerged from one of the most painstaking studies of climate changes ever attempted and reinforce the theory that the earth's climate is unstable and can switch between warm and cold incredibly quickly.

His conclusions, published in New Scientist, are based on a study of mud deposits extracted from a lake in Western Ireland, Lough Monreagh - a region he describes as having the 'best mud in the world in scientific terms'.

Professor Patterson used a precision robotic scalpel to scrape off layers of mud just 0.5mm thick. Each layer represented three months of sediment deposition, so variations between them could be used to measure changes in temperature over very short periods.

excellent find, kinda blows those other theories out of the water now doesn't it of course it won't stop the gov't from trying to tax us into oblivion before the freeze hits.

The problem with this is that there is no Lake Agassiz equivalent existing today.

Greenland was so warm about 1000 year ago that the Vikings grew grapes there. This means that the ice cap must have have been vastly reduced, with no stoppage of the gulf stream and ice age.

Perhaps the combination of underwater volcanoes melting the arctic ice AND the Greenland ice sheet melting substantially (cause?) would be enough to alter the salinity of the North Atlantic enough to alter the Gulf stream.

Actually they didn't grow grapes in Greenland. They did, however, grow wheat and rye in Greenland. It was northern England and Scotland they were growing grapes and I do believe olive trees, the climate there is not temperant enough now to do so.

K-

okee, dokee.

But, nonetheless, the amount of fresh water needed to precipitate an ice age in 6 months is simply not there. An ice age over a few short years is more likely.

I think I read somewhere recently that Greenland glaciers are actually thickening. If true, then fresh water runoff is much slower now. It's hard to know what to believe anymore.

There is a HUGE lake under the Antarctic icecap that we hear very little about. They are drilling into it and many are very worried about that.

I think there's a thread on it in here is Earth Changes.

It's Lake Vostok

They have look at them mud samples over hundreds of times and back in the 70s came to the conclusion that the last ice age came about quite quickly. Now other research has shown the this planet froze over a number of times and it did not have some kind of lake spilled over each time, so there has to be something more to what brings on an ice age.

We may be witnessing the start of an ice age with the sun in a Grand Solar Minima and the solar system passing threw the galactic plan and who knows just what combination of events it takes to really bring on an ice age.

I am of a strong belief it is solar. Something cometh (again) to make life uncomfortable for most. At least those that survive it.

Having read Robert Felix's Ice Age Now and other items supporting of his theory of sudden onset of ice ages, none of this surprises me. Some of his dots are a bit ephemeral, but the overall patterns are clear and frightening. Got Gardens?

Volcano that gave rise to Atlantis legend re-awakens
by ROBERT on MAY 13, 2012

Cataclysmic eruptions at the Greek isle of Santorini about 3,600 years ago spewed out 9.5 to 14.3 cubic miles (40 to 60 cu km) of lava that devastated the ancient Minoan culture, and may have inspired the legend of the lost city of Atlantis.

Since that huge eruption, which affected the environment as far away as China and perhaps even North America and Antarctica, Santorini has experienced a series of smaller eruptions that ended in 1950. After a 60-year lull, the volcano re-awakened in January 2011.

Fortuitously, scientists had installed a GPS monitoring system in the area in 2006. In June 2011, they noticed that their GPS stations had moved 0.2 to 1.3 inches (5 to 32 mm) farther from the caldera (which is mostly underwater) than just six months earlier. By January 2012, the movement had accelerated, reaching 7 inches (180 mm) of growth per year.

Computer models suggest that the swelling is due to an influx of nearly 500 million cubic feet (14.1 million cubic meters) of magma into a chamber 2.5 to 3.1 miles (4 to 5 km) below the surface.

This influx of magma does not necessarily signal an impending explosion, the scientists assure us. “However, we cannot say for certain that this will not erupt either.”

Even if it should erupt, 9.5 cubic miles of lava “represents only about 0.03 percent of the estimated eruptive volume from the monstrous 1650 B.C. eruption—not nearly enough for a repeat performance,” says Discovery.com. “Should Santorini erupt, it will most likely be a relatively tame event.”

My concern of course, is the cumulative effect of so many volcanoes going off around the world. And how many underwater volcanoes are now erupting that we aren’t even aware of?

Warmer oceans and cooler skies – a deadly combination.

==========================
fair use ... that last line is telling as the warmer oceans increase precipitation that the cooler skies (due to sun, cometary dusting,dark star, realm border etc) then make the most of... like in the film Day After Tomorrow... the channeled data says it happens much, much, much faster than we think... like that flower blossum in that mastodon's stomach... flash frozen.... that's fast. Given the way the science has gone on this issue, the time frame of the evidence keeps contracting so that that film might indeed be rather accurate. The signs are already all around us, just the trigger event that pushes the game into 'tilt'.

I'm still going through another 'channeled' source that started mentioning this 'twin star' back in the late 50s, the data isn't as specific as Laura's Cassiopaeans, but it is there nevertheless, and stating about the same things mostly about the binary star coming in and causing a repositioning of our solar system as the center of gravity is readjusted. Interesting. The thing about the Moon I've yet to see mentioned anywhere else, so I don't know about that possibility as all choices affect events especially in the temporal mode. What's gonna happen is gonna happen, but when exactly is harder to delineate.

Here's another one from Iceagenow:

Massive volcanic eruptions triggered Little Ice Age
by ROBERT on MAY 14, 2012

This is why I fear all the volcanic eruptions we’re seeing today.

“The Little Ice Age began in the 1300s due to the cooling effect of massive volcanic eruptions,” says this article on BBC news (30 Jan 2012).

A study led by Dr Gifford Miller at the University of Colorado in Boulder found four explosive volcanic eruptions between about 1250 and 1300 that would have blasted huge clouds of sulphate particles into the upper atmosphere, cooled the Earth for centuries, and triggered glacial expansion.

Although the temperature declined less than 1C globally, parts of Europe cooled more than that, particularly in the winter, which explains the thick layer of ice that formed on the River Thames during so many winters at the time.

Studying ancient plants and glacial sediments at several sites in Canada and Iceland, the scientists determined that the cooling began fairly abruptly between 1250 and 1300, then fell another notch between 1430 and 1455.

Analysis of the later phase of the Little Ice Age also suggests that changes in the Sun’s output, particularly in the ultraviolet part of the spectrum, would also have contributed cooling.

Underwater volcano bigger than Mt Vesuvius erupts – Video
by ROBERT on MAY 15, 2012

And we didn’t even know it!

Researchers studying the Monowai volcano near Tonga recorded huge changes in height in just two weeks. This latest analysis compared images gathered on May 14 and then June 1-2 last year and even in that short period the volcano had undergone a transformation.

The team found that one volcano, named Monowai, changed dramatically over just a two week time span, collapsing in one part and adding almost 80 meters of height in another. The team has described their findings in a paper published in the journal Nature Geoscience.

“The researchers believe the changes are larger than at most other volcanoes. Only Vesuvius and Mount St Helens have recorded larger growth rates.”

Bigger than Mount Vesuvius! That’s the huge volcano that buried Pompeii, and no one
even knew that it had erupted! And we wonder what has been heating the seas?

“A wake-up call that the sea-floor may be more dynamic than we previously thought,” says lead author Tony Watts of Oxford University. “I’ve spent my career studying the seabed and have generally thought it pretty stable so it’s stunning to see so much change in such a short space of time.”

As many as 32,000 underwater mountains have been identified around the world and the majority are believed to be volcanic in origin,” says this article by David Shukman. ” Several thousand of these may be active but a combination of ocean depth and remoteness means that very few have been studied.”

They keep sending that lil robot thingy down under water and it continiously reveals vents, volcanoes, etc. and yet they are still suprised. Truth be known the entire pacific rim is one large super volcano! Just like that area in the gulf, supposedly hit by a meteorite, is also a super volcano.

Yeah, looking more like the moon all the time, only we all that water and wars over the land, little of this knowledge is known, especially after all the book burnings.

Last Ice Age arrived in just six MONTHS
by ROBERT on MAY 20, 2012

‘It would be the equivalent of taking Britain and moving it to the Arctic over the space of a few months.’

It took just six months for a warm and sunny Europe to be engulfed in ice, according to this study

According to geological sciences professor William Patterson, who led the research, ‘It would be the equivalent of taking Britain and moving it to the Arctic over the space of a few months.’

Professor Patterson’s findings reinforce the theory that the earth’s climate can switch between warm and cold incredibly quickly.

Professor Patterson scraped off layers of mud just 0.5mm thick from a lake in Western Ireland. Each layer represented three months of sediment deposition, so he could measure changes in temperature over very short periods.

He found that temperatures had plummeted, with the lake’s plants and animals rapidly dying over just a few months

The subsequent mini Ice Age lasted for 1,300 years.

It may have been a ‘mini’ ice age geologically speaking, but for anyone living at the time, 1,300 years would have spanned how many generations?

Let’s see. If you take 1,300 years and divide it by 21, you get 61 generations.

=================

Of course, people on average didn't live as long, but reproduced earlier on average thus the 21 year generational cycle instead of what today might be considered 30, IMO anyway. Nevertheless, the next question is when exactly and whether it's a 'little' one or the real deal.

We know too little about the Sun, despite all our efforts since the XVII century, but one thing is strikingly evident from all these studies, i.e., the cyclic nature of the solar radiation and its obvious, direct influence on Earth’s climate, with scales from few years to many thousands of years.

It seems that these very cycles are telling us that the new Ice Age is coming.
