Record Cold ‘Blob’ in North Atlantic: Sign of Future Climate Woes? Some scientists are saying new data from the National Oceanic and Atmospheric Administration could point to weakening of a North Atlantic ocean current
Last week, I grabbed the above screen shot of the Weather Satellite image, because the initial GOES image I saw of the N. Atlantic low pressure area looked ominous and seemed to directly reinforce the article I posted 0n 8 April from Common Dreams titled “Climate Change to Bring ‘Superstorm Sandys’ to Europe” which can be found below. Three days ago the WASHINGTON POST published the following story by AP>>>
Published: October 27
LONDON — A savage coastal storm powered by hurricane-force gusts slashed its way through Britain and western Europe on Monday, felling trees, flooding lowlands and snarling traffic in the air, at sea and on land. At least 13 people were reported killed.
It was one of the worst storms to hit the region in years. The deadly tempest had no formal name — and wasn’t officially classified as a hurricane due to a meteorological standard — but it was dubbed the St. Jude storm (after the patron saint of lost causes) and stormageddon on social networks.

In the new study, researchers were able to assemble a record of rainfall for the eastern Mediterranean dating back about 3,500 years.
Researchers first drilled a core about 27 feet long from the bed of the Larnaca Salt Lake on the island of Cyprus — a major center of ancient eastern Mediterranean trade — and used radiocarbon dating to determine the age of each sediment layer.
Then they examined the 84 pollen grains preserved within the core. They identified the tree species each grain came from, producing a time line of the vegetation cover in the region.
They found that lush woodlands gave way to arid grasslands about 3,200 years ago, marking one of “the driest [periods] of the last 5,000 years in the eastern Mediterranean region,” said Joel Guiot, a paleoclimatologist at Aix-Marseille University in France and a study coauthor.
Analysis of marine fossils in the core revealed that the site was once a bustling harbor that eventually dried into a landlocked salt lake, probably disrupting trade and farming. Researchers also recovered less charcoal in more recent sediments, indicating less fire building and, it would stand to reason, fewer people.
Their findings closely match archaeological evidence of the collapse of civilizations in the region. The last trace of Late Bronze Age artifacts dates to the same time as the climate shift, while hieroglyphs and cuneiform texts describe famines and waves of mysterious “sea people” raiding Egypt, Turkey, Syria and Palestine’s shores about the same time. Archaeologists can now conclude they were probably eastern Mediterraneans fleeing their inhospitable homelands, seeking new areas to settle.
By combining environmental and archaeological data, the study marks “the first time we have anything resembling a crime scene investigation in archeology,” Drake said. “Climate has been caught red-handed.”
He added, “We tend to focus on political, human-driven problems, but there isn’t a human driver for the destruction that matches what happened 3,000 years ago.”
Update 04/09/2013 ——————————————————
The article below adds to the possible scenario postulated in THE COMING GLOBAL SUPERSTORM and THE DAY AFTER TOMORROW by introducing an abundance of extremely moist air from the eastern Atlantic into a much colder northern Europe and much of Great Britain.
Hurricanes and extratropical storms will bring ‘far reaching consequences’
Hurricane Sandy may have been a harbinger of storms to come to Europe, new research shows, as more details about the destructive climate impact greenhouse gases are bringing the planet come to light.
Extratropical cyclone named Xynthia brought hurricane-force winds and high waves to Western Europe at the end of February 2010. (MODIS Rapid Response Team at NASA Goddard Space Flight Center) Global warming brings a warmer Atlantic Ocean, and will create “more frequent and intense hurricanes following pathways directed towards Europe,” according to a new paper in the journal Geophysical Research Letters.
The following tweet caught my eye this morning
Our terrible spring: the winners and the losers http://gu.com/p/3fxvm/tf
so I clicked on the link which lead me to the below investigation about the effects of climate change on the Gulf Stream and the implications of its slowing down.
The cold has been good for energy firms and blokes selling dodgy scarves on the market. For the rest of us, not so much
It’s cold. You may have noticed. We have just emerged from the coldest March since 1962 into an April showing few signs of improvement. The long winter has blighted our wildlife and livestock, harmed our health and sparked fears of a triple-dip recession. But a few people – woolly-hat sellers, for example – have had a frozen field day. Here are the long winter’s top winners and losers.
The Gulf Stream that circulates from south of Florida to the North Atlantic carries enough thermal energy to usually pump into the British Isles average weather an extra 5 to 10 degrees F. One of the possible causes of the recently experienced bad weather would be a slowdown in the Gulf Stream, so I searched for evidence and found a marked change in reporting on the subject just in the past three years of articles about the Gulf Stream slow down.
The Mail Online reported in 2010
New climate change myth: Gulf Stream is NOT slowing down
By David Derbyshire
UPDATED: 04:59 EST, 30 March 2010
Fears that global warming will shut down the Gulf Stream and plunge Britain into a mini-ice age are unfounded, a study shows.
There is no evidence the phenomenon – which brings a constant flow of warm water and mild weather to northern Europe – has slowed down over the past 20 years, climate scientists say.
‘The changes we’re seeing in overturning strength are probably part of a natural cycle,’ said researcher Josh Willis, from Nasa.

To contrast that is the following article from this past February on The Weather Channel
East Coast Faces Rising Seas from Slowing Gulf Stream
Michael D. Lemonick, Climate Central Published: Feb 18, 2013, 11:41 AM EST
Experts on the sea level rise triggered by climate change have long known that it will proceed faster in some places than others. The mid-Atlantic coast of the U.S. is one of them, and the reason — in theory, anyway — is that global warming should slow the flow of the Gulf Stream as it moves north and then east toward northern Europe.
Now there’s a smoking gun that appears to validate the theory. A study in the February Journal of Geophysical Research: Oceans ties the measured acceleration of sea level rise in this area to a simultaneous slowdown in the flow of the Gulf Stream . . .
While scientists expect sea level to rise by about 3 feet over the next 90 years or so, in places like New York City and Norfolk, Va., it could be significantly more. New York, where sea level is already a foot higher than it was in 1900, was just reminded of what happens when higher seas are pushed ashore by a major event like Superstorm Sandy.
The article incorporates the term “SUPERSTORM” which was popularized in the 2004 movie THE DAY AFTER TOMORROW which was based on the highly criticized book THE COMING GLOBAL SUPERSTORM but the following Forbes article vindicates the science Whitley Strieber and Art Bell wrote of in their book 15 years ago.

Covering Brazil, Russia, India & China. Update 11/07/2012
In 1999, before Al Gore taught the world about climate change, an ex-horror fiction writer named Whitley Streiber and a supernatural radio show host named Art Bell joined forces to write The Coming Global Superstorm. It was a climate catastrophe story, but it wasn’t a novel. It was non-fiction …
In 2000, a year after Superstorm was published and six years before Gore’s much more popular “Inconvenient Truth”, Streiber wrote on his website Unknown Country that ”the situation is so bad right now that it takes my breath away. It’s much, much worse than I ever dreamed possible. Essentially, the reason is that crucial currents, especially in the northern oceans, are under attack from very rapid climate change. As Superstorm points out, when these currents change course, the world’s climate is drastically altered. Whether a gigantic storm or series of storms is involved or not, there is going to be a cascade of climatic change accompanied by extraordinary weather violence over the next few years. I feel that the process has already started, and much earlier than we imagined possible just twelve months ago.”
What I see these articles pointing to is more extreme weather ahead which is amplified by the following on THE WEATHER CHANNEL today
More Dangerous Pattern Ahead
Why our turbulent weather is getting even harder to predict
- The Observer, Saturday 6 April 2013
The cold snap, fingers crossed, is about to end. But extreme weather – snow, floods and drought – is the new norm.
Britain’s weather excelled itself last week. It produced an Easter Sunday that was the coldest on record in the UK. Temperatures stuck below zero in many regions; freezing conditions continued to disrupt transport; and experts warned of increasing threats to animals and birds already struggling to survive loss of habitat and climate change. The start of British Summer Time last Sunday night was marked in Braemar by temperatures that fell to -11C. For good measure, an unappetising April looks likely to follow this misery.
but,what is most concerning of all the news about the Gulf Stream lately though is the potential of a major methane gas release as explained in this article on MSNBC
In this visualization, the Gulf Stream is seen as the dark red current coming into the Atlantic from the Gulf of Mexico.
A changing Gulf Stream off the East Coast has destabilized frozen methane deposits trapped under nearly 4,000 square miles of seafloor, scientists reported Wednesday. And since methane is even more potent than carbon dioxide as a global warming gas, the researchers said, any large-scale release could have significant climate impacts.
Temperature changes in the Gulf Stream are “rapidly destabilizing methane hydrate along a broad swathe of the North American margin,” the experts said in a study published Wednesday in the peer-reviewed journal Nature.
