Last Ice Age happened in less than year say scientists
The Scotsman ^ | 8-02-08 | angus howarth

Posted on 08/02/2008 2:28:28 PM PDT by Renfield

THE last ice age 13,000 years ago took hold in just one year, more than ten times quicker than previously believed, scientists have warned. Rather than a gradual cooling over a decade, the ice age plunged Europe into the deep freeze, German Research Centre for Geosciences at Potsdam said.

Cold, stormy conditions caused by an abrupt shift in atmospheric circulation froze the continent almost instantly during the Younger Dryas less than 13,000 years ago – a very recent period on a geological scale.

The new findings will add to fears of a serious risk of this happening again in the UK and western Europe – and soon.

Dr Achim Brauer, of the GFZ (GeoForschungs Zentrum) German Research Centre for Geosciences at Potsdam, and colleagues analysed annual layers of sediments, called "varves", from a German crater lake.

Each varve records a single year, allowing annual climate records from the region to be reconstructed.

Thanks Renfield.
The last ice age 13,000 years ago took hold in just one year, more than ten times quicker than previously believed, scientists have warned. Rather than a gradual cooling over a decade, the ice age plunged Europe into the deep freeze, German Research Centre for Geosciences at Potsdam said. Cold, stormy conditions caused by an abrupt shift in atmospheric circulation froze the continent almost instantly during the Younger Dryas less than 13,000 years ago -- a very recent period on a geological scale.
Funny thing, no one seems to have noticed that "more than ten times quicker" suggests that previously, the onset was held to be a short period, say, twenty years. At least one study which found that a large volume of chilly water flowed all at once into the Atlantic came out around ten years ago.
Did A Significant Climate Change Event,
Known As Younger Dryas,
Impact Climate Around The Globe?

ScienceDaily
July 22, 2008
The Younger Dryas event refers to an unexpected rapid cooling of the earth that is known to have lasted about 1,300 years. It coincided with widespread extinctions of species, but, although the event itself is well-documented, scientists are still unclear of whether its impact was felt equally all across the globe.
And prior to perhaps twenty years ago, the "ice ages" were held to have taken centuries, even millennia, to arise.

The conclusion was reached from studying sediments but there was no proximate cause proposed for the observed condition.

Okay. I must have my Ice Age lakes mixed up. I thought lake Agassiz flooded the Columbia River basin into the Pacific.

Which one was that?

By placing the kid on the spaceship for other places, the kid at least stood a chance! With Albore for a father, the kid was destined to fail back here on planet earth!

Albert Einstein is oft quoted that "God doesn't play dice with the universe". Perhaps the socialist/communist envirowhacko's should start taking notes, on who is in charge - and then pay attention - Albore notwithstanding.

One idea is, as the edge of the icecap receded north, instead of running off into the Mississippi River, it ran into the newly uncovered St Lawrence.

The theory sort of makes sense when you consider how long it takes to melt snow in heavy snowfall winters.

For example, there is an area in my neighborhood where the snowplows push a lot of the snow, it's an empty lot on the corner of a residential intersection that is surrounded by tall trees so that spot is always in the shade. It is always where the last of the snow melts in the spring.

Well usually the snow is completely gone from that spot by mid-April but this year, but due to some heavier than normal snowfall this winter there was still snow there at the beginning of May! And this was after we had a two-week period where daytime temps were mostly in 60s and 70s.

Now I checked the weather conditions for my area and we received 73 inches of snow against an average of 52 inches. So the snowfall was only about 30% higher than normal.

SO what if we received double the normal amount of snow? Likely we would have had snow hanging around in that spot until the middle of June. This is not unprecedented in my lifetime. During the winter of 1977-78, this area received about 115 inches of snow and there were indeed snow piles around these parts into June that year.

So let's say we get a very heavy amount of snow across the upper third of the U.S. The snowpack will keep temperatures cooler in the spring and with that much snow combined with cooler than normal spring and summer temperatures, it's quite possible we would hang on to much of that snowpack through the summer.

Then when the snows start up again that winter, it will be on top of snow from the year before and the tipping point will be reached. By spring, the snowpack will be so entrenched that it will never get warm enough in summer to melt it all and suddenly a good part of the United States is now officially in an ice age.

During the winter of 1977-78, this area received about 115 inches of snow and there were indeed snow piles around these parts into June that year.

The last place to melt that year at my house was a snow drift about 2 times the distance from the house as the height of the house to the southwest. Basically a big drift created by the house in the Blizzard of 78. When I was hiking in the White Mountains that year, there were some big drifts left in June. I think it would take a much more extreme winter for the snow to last through the July and August sun and thunderstorms, but it could happen, or I should say, will happen, with the right conditions.

The risk of falling through ice lakes on the highway to the diamond mines goes down . . .

You a fan of "Ice Road Truckers?" Love that show. I'll miss Alex though but according to the forum on the History Channel's website, he is doing fine. BTW, I also like Hugh but Rick is getting on my nerves. In season one, Rick did have a legitimate gripe about no heat in Hugh's truck but now he is a whiner. He complains about hauling garbage, yet Hugh hauls sewage and takes it in stride.

It should be pointed out that this applies strictly to Europe. Something pretty similar could happen today if the Gulf Stream was diverted for some reason. London is north of the US-Canadian border.

I think there were changes in the Gulf Stream in the early 1960's and Britain did have a nasty winter in 1961/62 or was it 1962/63? You can find videos on it on YouTube. IIRC, when the Beatles toured England at that time, their van hit an ice patch and all their equipment shifted and landed on George Harrison, he was beat up for weeks.

They were found in Silver Springs, I think, along with Giant Sloth bones.
