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.
You are thinking of Lake Bonneville, the ancestor of the Great Salt Lake, formed about 30,000 BC from glacial runoff, drained into the Columbia River through Idaho around 124,000, probably due to continued glacial melting.
It seems to me that distinctions are being blurred between the long deep cold climatic conditions that last from 60-120k years and cyclic dips in conditions during the intermediate warm periods that last from approx. 15-30k years. The former used to be called Ice Ages now every period of lower temps in the warm intermediate periods is also called and Ice Age. And then some say it's all an Ice Age as long as some ice remains on the polar caps. The term is being rendered meaningless.
My gosh, we're in an Ice Age right now.
No, they were found close to CR 318 in Citra when my sister was digging a pond. We took them to UF for identification. They said lots of bones are found in this area.
The way it's going if we get a thunderstorm that chills us off this afternoon I'm going to call it an Ice Age.
Such a sudden climatic shift to an ice age would be really super beneficial in limiting, or at least slowing down, the coming fire storms of global warming.
Just think it through for a sec. If we do get a sudden, full blown, ice age.... then we won’t need to run our refrigerators and ice makers so much. Think of all the wasted energy that would be saved by that?
Seque, anyone???
No one ever fell off a ladder without climbing it first.
Please tell me that someone has forced the goreghoul to read this.
We are still in an ice age...we’re just in one of the relatively short interglacial periods-—and, judging by the length of past interglacials, at the tail end of ours, at that.
No, he is thinking of Glacial Lake Missoula. That’s the one that drained rapidly (and sequentially), forming the channeled scablands of Washington State.
Lake Bonneville disappeared mostly due to evaporation (hence the salt deposits at Great Salt Lake).
It isn’t snowy winters that make an Ice Age, it’s cold summers.
That's cuz Texas is hogging the heat this year. We were cool and rainy last year, but now we're doing penance for the comfort we experienced then.
OK, interglacials is the term then. And when there’s a temporary re-cooling during an interglacial period that is an Ice Age also. Maybe, for clarity, we could call those inter-Ice Ages to distinguish them from glacial-Ice Ages which of course aren’t overall-Ice Ages.
The book “The Chilling Stars” explains how a mild reduction in the solar output leads to greatly increase low-level clouds (which have a cooling effect) and thus increases the impact of a quieter sun.
For example, there is NO miles-thick ice layer covering areas of North America that could melt. (Last time I was up there, North Dakota was very much NOT ice-covered. I understand small parts of Canada are ice free - for small parts of the year at least.
The article is stressing the “potential” for the massive climate changes (the “tipping points” that Hansen WANTS to be accepted as fact) that the AGW extremists are trying to palm off on a gullible public.
Global Warming is caused by Global Cooling. It is as plain as day. In medieval logical terms:
So please, members of the VRWC, do not argue against logic. Do I have to get Obama to 'splain this?

Global temperatures drop precipitously

Fastest temperature change ever recorded

Nearly wipes out 100 Years of Global Warming

26 Feb 08 - Excerpt: All four major global temperature tracking outlets (Hadley, NASA’s GISS, UAH, RSS) have released updated data. All show that over the past year, global temperatures have dropped precipitously.
.
World Temperatures according to the Hadley Center for Climate Prediction
Note the steep drop over the last year.
Meteorologist Anthony Watts compiled the results of all the sources. The total amount of cooling ranges from 0.65C up to 0.75C — a value large enough to erase nearly all the global warming recorded over the past 100 years.
All in one year’s time.
For all tracking outlets, it’s the single fastest temperature change every recorded, either up or down.
Well, take it back! It’s in the Mid 50’s right now. Stupid globull warming!
