Mini ice age took hold of Europe in months
New Scientist ^ | Nov 11, 2009 | Kate Ravilious

JUST months - that's how long it took for Europe to be engulfed by an ice age. The scenario, which comes straight out of Hollywood blockbuster The Day After Tomorrow, was revealed by the most precise record of the climate from palaeohistory ever generated.

Around 12,800 years ago the northern hemisphere was hit by the Younger Dryas mini ice age, or "Big Freeze". It was triggered by the slowdown of the Gulf Stream, led to the decline of the Clovis culture in North America, and lasted around 1300 years.

Until now, it was thought that the mini ice age took a decade or so to take hold, on the evidence provided by Greenland ice cores. Not so, say William Patterson of the University of Saskatchewan in Saskatoon, Canada, and his colleagues.

No!

Wasn't it millions of years?

How can it only be MONTHS?

Sarcasm off. I suppose it depends on Who you see as being in charge. God or man? God can do whatever He wants as quickly or as long as He wants it to be.

There are a number of scientists who speculate some sort of impact event--either from a big meteor or comet--some 12,800 years ago that essentially wiped out just about all mammal life forms, including a fairly sizable early homo sapiens population--in North America itself. That's why human culture in North America was so distinctly different before and after that supposed impact.

Lake Agassiz would do that.

Thanks decimon! The medieval "Little Ice Age" also took hold quickly.

Years ago there was a show on PBS about climate.

Some egghead types had gone into Canada somewhere to take core sediment samples from a lake, I forget which one.

By studying the size of the sediment particles, the pollen in the samples, etc. They were able to map out timewise exactly how long it had taken from this particular area to go from a moderately warm, temperate climate to full-scale, deep freeze ice age.

We’re talking glaciers and ice caps hundreds of feet thick.

Ninety years.

Patterson's team have now set their sights on even more precise records of historical climate. They have built a robot able to shave 0.05 micrometre slivers along the growth lines of fossilised clam shells, giving a resolution of less than a day. "We can get you mid-July temperatures from 400 million years ago," he says.

Impressive, if they can pull this off.

Git-r-done.

Didn’t it seem like just a month or two ago it was warm and now when I go outside I freeze to death. How can that happen. Weird.

Being a bit geezerly I recall some speculations from decades ago. One was that ice ages do or can occur quickly.

Someone claimed there were fossils showing animals frozen while still eating. The reason for that was speculated to be the Earth shifting suddenly on its axis. That would of course mean a shifting of the frozen poles and not a general cooling of the planet.

I wonder what made the old shorelines so straight and right-angled?

So now we have three sizes of ice ages?

There are Little Ice Ages, like those of the Dark Age and the late Medieval period, which bring great illnesses and crop failures. There are mini Ice Ages, like the Later Dryas, which cause cataclysmic regional population collapses. Lastly full scale Ice Ages, which bring cataclysmic climate change on a global level.

Has much been done to quantify these distinctions?
