Big Freeze Plunged Europe Into Ice Age in Months

In the film, The Day After Tomorrow, the world enters the icy grip of a new glacial period within the space of just a few weeks. Now new research shows that this scenario may not be so far from the truth after all.

William Patterson, from the University of Saskatchewan in Canada, and his colleagues have shown that switching off the North Atlantic circulation can force the Northern hemisphere into a mini 'ice age' in a matter of months. Previous work has indicated that this process would take tens of years.

Around 12,800 years ago the northern hemisphere was hit by a mini ice-age, known by scientists as the Younger Dryas, and nicknamed the 'Big Freeze', which lasted around 1300 years. Geological evidence shows that the Big Freeze was brought about by a sudden influx of freshwater, when the glacial Lake Agassiz in North America burst its banks and poured into the North Atlantic and Arctic Oceans. This vast pulse, a greater volume than all of North America's Great Lakes combined, diluted the North Atlantic conveyor belt and brought it to a halt.

Without the warming influence of this ocean circulation temperatures across the Northern hemisphere plummeted, ice sheets grew and human civilisation fell apart.

Tourist beachgoers wrap up as Arctic blast hits so-called Sunshine State

Across the so-called Sunshine State, oranges and strawberries are freezing, icicles are hanging off palm fronds, and iguanas paralyzed by the cold are falling out of trees.

Temperatures have plunged as low as the 20s in recent days, forcing people used to wearing flip-flops year-round to put on earmuffs.

"I am a warm-weather boy. There's no way I'm going out there," laughed Archie Adkins of Pensacola Beach as he pointed at bundled-up beachgoers.

The bitter winter afflicting much of the Northern Hemisphere is only the start of a global trend towards cooler weather that is likely to last for 20 or 30 years, say some of the world's most eminent climate scientists.

Their predictions - based on an analysis of natural cycles in water temperatures in the Pacific and Atlantic oceans - challenge some of the global warming orthodoxy's most deeply cherished beliefs, such as the claim that the North Pole will be free of ice in summer by 2013.

According to the US National Snow and Ice Data Centre in Colorado, Arctic summer sea ice has increased by 409,000 square miles, or 26 per cent, since 2007 - and even the most committed global warming activists do not dispute this.

Bering Strait influenced ice age climate patterns worldwide

Boulder -- In a vivid example of how a small geographic feature can have far-reaching impacts on climate, new research shows that water levels in the Bering Strait helped drive global climate patterns during ice age episodes dating back more than 100,000 years.

The international study, led by scientists at the National Center for Atmospheric Research (NCAR), found that the repeated opening and closing of the narrow strait due to fluctuating sea levels affected currents that transported heat and salinity in the Atlantic and Pacific oceans. As a result, summer temperatures in parts of North America and Greenland oscillated between warmer and colder phases, causing ice sheets to alternate between expansion and retreat and affecting sea levels worldwide.

While the findings do not directly bear on current global warming, they highlight the complexity of Earth's climate system and the fact that seemingly insignificant changes can lead to dramatic tipping points for climate patterns, especially in and around the Arctic.

The death toll from Britain's biggest freeze for decades reached 22 today as the country prepared for its coldest night so far, bringing the promise of even more treacherous conditions.

Thousands of homes have been left without power, schools have closed and travellers have faced chaos as the weather hit roads, rail services and airports over the last two days. The disruption is estimated to have cost businesses around £700 million.

Councils continued to struggle with a growing salt emergency as police warned drivers in many areas not to travel unless their journey was essential.

The AA expect to have attended 20,000 breakdowns today - compared with about 9,000 for a normal Thursday - and warned that conditions were expected to remain "treacherous".

Meanwhile, the shutdown of an offshore Norwegian gasfield pushed Britain's gas infrastructure into emergency mode, forcing the closure of industrial companies in the north of England in order to preserve supplies to homes, shops and offices.

Although major airports stayed open, some air passengers had long waits for their flights, particularly at Gatwick, on the outskirts of south London, where more than 130 flights were cancelled. EasyJet had to axe more than 100 flights and British Airways was among other carriers that had to cancel some services.

The body of Philip Hughes, 45, from Slough, was recovered from beneath ice at the Lakeside Country Club in Surrey where he was watching the world darts championship. A spokesman said it appeared to have been a "tragic accident".

Vehicles travel in white out conditions caused by blowing snow on Interstate 80 west of Omaha, Neb., Wednesday, Jan. 6, 2010. A storm system with sub-freezing temperatures and high winds is traveling through the Midwest.
Des Moines - Snow was piled so high in Iowa that drivers couldn't see across intersections and a North Dakota snowblower repair shop was overwhelmed with business as residents braced Thursday for heavy snow and wind chills as low as 50 below zero.

Frigid weather also was gripping the South, where a rare cold snap was expected to bring snow and ice Thursday to states from South Carolina to Louisiana. Forecasters said wind chills could drop to near zero at night in some areas.

Dangerously cold wind chills were anticipated in the Midwest overnight, including as low as 35 below in eastern Nebraska, minus 45 in parts of South Dakota and negative 50 in North Dakota, according to National Weather Service warnings.

Another 10 inches of snow was expected in Iowa, buried in December by more than 2 feet of snow, while up to 9 inches could fall in southeast North Dakota that forecasters warned would create hazardous zero-visibility driving conditions. Wind gusts of 30 miles per hour were expected in Illinois - along with a foot of snow - while large drifts were anticipated in Nebraska and Iowa.

The Coming Ice Age

Short of a catastrophic asteroid impact, the greatest threat to the human race is the onset of another ice age.... Global warming predictions by meteorologists are based on speculative, untested, and poorly constrained computer models.... our knowledge of ice ages is based on a wide variety of reliable data, including cores from the Greenland and Antarctic ice sheets. ... By reducing our production of carbon dioxide, we risk hastening the advent of the next ice age. Even more foolhardy and dangerous is the Obama administration's announcement that they may try to cool the planet through geoengineering. Such a move in the middle of a cooling trend could provoke the irreversible onset of an ice age. It is not hyperbole to state that such a climatic change would mean the end of human civilization as we know it.


Comment: The above remarks from this thoughtful article provoke the unavoidable speculation that the PTB are TRYING to induce another ice age with their global warming nonsense. Who needs WMDs when you can kill billions by starvation and freezing cold?

Our near future?
Those who ignore the geologic perspective do so at great risk. In fall of 1985, geologists warned that a Columbian volcano, Nevado del Ruiz, was getting ready to erupt. But the volcano had been dormant for 150 years. So government officials and inhabitants of nearby towns did not take the warnings seriously.

On the evening of November 13, Nevado del Ruiz erupted, triggering catastrophic mudslides. In the town of Armero, 23,000 people were buried alive in a matter of seconds.

For ninety percent of the last million years, the normal state of the Earth's climate has been an ice age. Ice ages last about 100,000 years, and are punctuated by short periods of warm climate, or interglacials. The last ice age started about 114,000 years ago. It began instantaneously.

Science: Another Ice Age?

Cover of Time magazine from December 1979
Comment: This article was originally published in Time Magazine on June 24, 1974. Now, considering the revelations about "Climategate", perhaps we need to return to what was known before greed and manipulation took over science?

In Africa, drought continues for the sixth consecutive year, adding terribly to the toll of famine victims. During 1972 record rains in parts of the U.S., Pakistan and Japan caused some of the worst flooding in centuries. In Canada's wheat belt, a particularly chilly and rainy spring has delayed planting and may well bring a disappointingly small harvest. Rainy Britain, on the other hand, has suffered from uncharacteristic dry spells the past few springs. A series of unusually cold winters has gripped the American Far West, while New England and northern Europe have recently experienced the mildest winters within anyone's recollection.

As they review the bizarre and unpredictable weather pattern of the past several years, a growing number of scientists are beginning to suspect that many seemingly contradictory meteorological fluctuations are actually part of a global climatic upheaval. However widely the weather varies from place to place and time to time, when meteorologists take an average of temperatures around the globe they find that the atmosphere has been growing gradually cooler for the past three decades. The trend shows no indication of reversing. Climatological Cassandras are becoming increasingly apprehensive, for the weather aberrations they are studying may be the harbinger of another ice age.

Is Nature Warning Us of a New Ice Age?

Global warming fears aside, all students of climate science know that the Earth is presently in an Ice Age and has been for approximately the past 2 to 2.5 million years. This Ice Age has been characterized by successive advances and retreats of a glacial ice sheet, originating in Greenland and extending across the northern portions of the North American and Eurasian continents. Just 12,000 years ago, the undisputed geological evidence shows that New York, Chicago, and all of North America up to the Arctic regions were under a sheet of ice, estimated to have been from 1 to 2 miles thick. Mountain glaciers also extended downward from the Rocky Mountains and the Appalachians in regions further to the south than the main glacial mass. A similar situation prevailed over most of Germany, northern France, the British Isles, Scandinavia, Poland and other parts of eastern Europe, and Russia.

Such had been the state of things on Earth for probably at least 100,000 years. Before that, a short period known as an interglacial had allowed for a warm climate somewhat like the present, and before it another extended period of glacial advance. The thaw which produced our present geography--the Great Lakes, the southward flowing Ohio River, and much else we take for granted--was not completed until about 8,000 to 9,000 years ago, according to the best estimates of geologists and climatologists. Not only were there changes in the internal geography, but the continental boundaries were also greatly changed during the glacial period. Calculations of the volume of water that must have been contained frozen in the continental glaciers, indicate that the global sea level, was lower by as much as 300 to 400 feet at times of glacial advance. A glaciation does not mean sea level rise, but a sharp fall in sea level exposing the continental shelf for miles out to sea. Much of the coastal-dwelling civilization of the past 100,000 or more years, thus lies buried offshore beneath hundreds of feet of ocean.

Can this happen again? The most plausible theory of the causes of the ice ages, the theory of astronomical determination, suggests that the time is ripe for it to happen sometime soon. A Jan. 11 article in the online edition of the Russian daily Pravda was titled "Earth on the Brink of an Ice Age."
