Mega-flood triggered cooling 13,000 years ago: scientists
Reuters on Yahoo ^ | 3/31/10 | David Fogarty

Posted on 03/31/2010 11:05:52 AM PDT by NormsRevenge

SINGAPORE (Reuters) – Scientists say they have found the trigger of a sharp cooling 13,000 years ago that plunged Europe into a mini ice age.

Mark Bateman from the University of Sheffield in England said a catastrophic flood unleashed from a giant North American lake dumped large amounts of freshwater into the Arctic Ocean.

This led to the shutting down of the Gulf Stream ocean circulation pattern that brings warmth to Europe.

"We're talking about a lake the size of the UK emptying very quickly," Bateman told Reuters by telephone. "We don't know the exact period of time but we're talking about a catastrophic flood."

The finding has confirmed past theories about the likely cause of a sudden cooling period called the Younger Dryas when temperatures in Europe, similar to today's, quickly returned to ice age conditions. The cooling lasted for about 1,400 years.

"Our research shows that if you put a large volume of fresh water into the North Atlantic in a very short space of time, this is what happens," Bateman said. His team's work is published in the latest issue of the journal Nature.

The Gulf Stream acts like a conveyer belt by bringing warm water from the tropics to Europe while cold salty water sinks to the depths in the far north. This "overturning" circulation draws in yet more warm water from the south.

Climate scientists fear rapid global warming could trigger a sharp increase in the amount of meltwater from Greenland. This surge in freshwater could trigger a tipping point that overwhelms the Gulf Stream, shutting it down and likely plunging Europe into another deep freeze.

I remember seeing a theory that the Great Basin in the cental U.S. was formed by a huge lake that was suddenly emptied, perhaps due to volcanic activity in the Yellowstone area. Don’t remember the time frame that was posited for it, though.

Where was the gigantic fresh water lake? Did they provide a location, some geology or fossil record to support their speculation. Or it this theoretical mumbling based on the exactitude of climate study models?

uummm didn't the last ice age end 10000 years ago, which means that at 13000 years ago it would have been still going strong. So how can you have a "mini ice age" on top of a real one??

The effect of the draining of Lake Agassiz on climate has been discussed for years. Why is this “finding” different from the other dozen or so “findings” (and why is a model result called a “finding”).

Second, I guess the good professor Bateman hasn’t been watching the Arctic ice trends lately. Greenland is in no danger of sudden melting.

Third, it has been demonstrated by buoy measurements (real data, not modelled “findings”) that the N. Atlantic conveyor has not been altered one iota.

First they say;
“”We’re talking about a lake the size of the UK emptying very quickly,”

Then they say;
“Climate scientists fear rapid global warming could trigger a sharp increase in the amount of meltwater from Greenland. This surge in freshwater could trigger a tipping point that overwhelms the Gulf Stream, shutting it down “

They ain’t goona get that kinda rapid melting in Greenland, unless the Sun goes nova! And the UK and Europe will melt, instead of going into a deep freeze!

There were several ice dam and other huge lakes after the last ice age. Lake Bonneville in Utah is another example. As you drive along the interstate going south, you can see the old shoreline up on the side of the mountains.

I'm pretty sure there was a large one in eastern Washington, too.

The theory I’ve understood is that there was massive global cooling causing serious hardship across the globe. The extreme cold caused the air to be very dry. While all this is going on a massive ice sheet is piling up on Antarctica. Due to the pressure between the land mass and the ice sheet heating occurs in between. This heat makes the ice slick against the continent and eventually it slides off into the sea. The resulting super tsunami covers the entire globe in water and Noah rides the wave.

The planet has been warmer than it is now numerous times in the last 14,000 years and that didn't happen. Their theory is not cohesive.

“Bateman found that the waters flowed down the Mackenzie River, Canada’s longest, rather than the Saint Lawrence Seaway that had previously seemed the most likely route.”

Bull. Loney.

Ancient Lake Agassiz flowed south to the Missippi River and the Gulf of Mexico (when blocked by the glaciers over Hudson Bay). It could not flow uphill to the Mackenzie Valley or through the Great Lakes to the St. Lawrence.

The climatologists get published in Nature and cannot even check an elevation map. Nature cannot even check an elevation map. The rush to support global warming is so strong that they just ignore facts which have been known for 150 years.

The continental divide is at Browns Valley Minnesota. North of Brown’s Valley, the water flows into Hudson Bay and the Arctic ocean. South of Browns Valley, the water flows south into the Gulf Mexico.

Brown’s Valley is only 200 feet higher than Lake Winnipeg and whenever the glaciers blocked access to Hudson Bay for melt water, it flowed south. The ancient river valley Warren is easily seen on topographic maps.

You can see the river channel and even the shoreline of Lake Agassiz at the top of this picture.

The problem with the sky-is-falling climate change alarmists is that there is no way that there could possibly be an
influx of fresh water of that magnitude from ice cap melt.

The ice caps just aren’t going to melt that fast.

The scenario that the article is describing would be more likely to happen in a situation like a dam bursting, not runoff from ice melt.

Satellite observations and computer models by scientists have shown that the Greenland ice sheet is melting at an accelerating rate, dumping large amounts of ice and meltwater into the North Atlantic.

No, its melting at a rate well within recent historic norms. On the other hand, the meltwater from the retreat of the North American continential glacial shield was a volume of water beyond all comprehension. The Great Lakes are the tiny puddles that were left over in the low spots. If this release was sudden, as occurred with the flooding of the Black Sea through the Bosphorus Strait, or the breach of the ice dam at Lake Missoula; then it was a truly significant event that may indeed have disrupted the Gulf Stream. The piddly little melting of today can do no such thing.

And they wonder why the public no longer takes them seriously.

It was Algore flying his plane around too much that caused the flood with global warming. Then he made the planet freeze because after it warms from human energy use sin, it always freezes. Everyone knows this! The science is settled and anyone who refuses to turn their cash and freedom over to Algore and his global Marxist pals is worse than the Nazis. ;)

Where do you find this stuff?

I have a bibliography on the last Ice Age that’s about 80 pages long with credible written research by the top people in the field. How did this get passed security and peer review?

There needs to be a MT Rushmore type image with hanson, gore, mann and that feller who heads up the IPCC. We will call it Mt Hockey Stick. Add this one to it.

I went looking around the web last night. I found a Spanish source talking about a cold snap 13K years ago. All my readings address a growing Ice Age that began 50K to 40K years ago and lasted until 10k years ago. They seem to be saying that we were leaving the ice age or left it and this pool of water took us back again.

It’s contrary to all I have read. This last ice age wiped out more than we know forcing the start or restart of civilization in Asia Minor 8,000 B.C.

I just don’t buy it.

From the Wiki:

****************************EXCERPT********************************

Lake Agassiz was an immense glacial lake located in the center of North America. Fed by glacial runoff at the end of the last glacial period, its area was larger than all of the modern Great Lakes combined, and it held more water than contained by all lakes in the world today.[1]

“I’m pretty sure there was a large one in eastern Washington, too.”

Yes. The Lake Missoula flood that ripped westward to the Pacific left huge channels, boulders, etc. the entire way. About once a month I have a nice view driving by a huge “ripple mark” - I imagine it is 100+ feet tall and several miles long!

And this flood he is talking about was not due to “rapid” melting. All of these glacial floods were the result of melting, but with an ice dam blocking the flow. The breakage of the dam was rapid, allowing a huge slug of freshwater to enter the ocean and screw up the equilibrium.

If for some reason that were to occur in Greenland, we could drill dam, allow water to flow at a regulated pace. And turn some turbines for hydroelectric at the same time!

FTA: "Climate scientists fear rapid global warming could trigger.."

Utterly predictable. I really wish the leftists would come up with a new scam, at least for the sake of variety.

There's evidence that the Canadian ice sheet, which apparently formed a giant ice damn to form a huge inland lake, failed catastrophically about 11,500 years ago, dumping an estimated one million cubic kilometers of fresh water into the ocean literally in the space of hours. This giant inundation would have also flooded the North Atlantic with fresh water. However, it didn't trigger a Younger Dryas III. The planet continued to warm and the glaciers continued to melt.

Just more nonsense from people who are paid explicitly to produce nonsense.
