Europe's deep freeze and global warming..

Much of Europe is in the throes of a killer deep freeze.  Hundreds of homeless and poor people have died already and to make matters worse, the gas supplies can not meet the increased demand.  Europe winter claims 250 lives, sends ferry aground

Hundreds of people were plucked to safety on Saturday after a ferry caught in a snow storm ran aground off Italy, as a vicious cold snap that has claimed over 250 lives across Europe refused to ease its clench.
Ukraine has suffered the heaviest toll of 122 deaths, including many people who froze to death in the streets, as temperatures plunged to as low as minus 38.1 degrees Celsius (minus 36.5 Fahrenheit) in parts of the continent.
But as Europe huddled indoors for warmth, Russian gas giant Gazprom said it could not satisfy western Europe's demand for more energy.
And I am sure there are the climate deniers who have heard about this story and said  "Har de Har Har, Where is all the global warming we keep hearing about??"

Well it turns out that scientists have predicted that a deep freeze in Europe would be the result of a steady rise in ocean temperatures.  This story came from NASA in 2004.

A Chilling Possibility:  By disturbing a massive ocean current, melting Arctic sea ice might trigger colder weather in Europe and North America.

March 5, 2004: Global warming could plunge North America and Western Europe into a deep freeze, possibly within only a few decades.
That's the paradoxical scenario gaining credibility among many climate scientists. The thawing of sea ice covering the Arctic could disturb or even halt large currents in the Atlantic Ocean. Without the vast heat that these ocean currents deliver--comparable to the power generation of a million nuclear power plants--Europe's average temperature would likely drop 5 to 10°C (9 to 18°F)... 
Some scientists worry that melting Arctic sea ice will dump enough freshwater into the North Atlantic to interfere with sea currents. Some freshwater would come from the ice-melt itself, but the main contributor would be increased rain and snow in the region. Retreating ice cover exposes more of the ocean surface, allowing more moisture to evaporate into the atmosphere and leading to more precipitation.

Because saltwater is denser and heavier than freshwater, this "freshening" of the North Atlantic would make the surface layers more buoyant. That's a problem because the surface water needs to sink to drive a primary ocean circulation pattern known as the "Great Ocean Conveyor." Sunken water flows south along the ocean floor toward the equator, while warm surface waters from tropical latitudes flow north to replace the water that sank, thus keeping the Conveyor slowly chugging along. An increase in freshwater could prevent this sinking of North Atlantic surface waters, slowing or stopping this circulation.

There is a 100% chance that sub-intelligent climate deniers (and stand-up comics) around the world will use the images and news from the European deep freeze as proof that global warming is hooey.  After all, why should mankind be concerned about the ice caps melting and the oceans warming when there are people are freezing to death.  The 2004 article from NASA points out the reason for concern.

A map of the world will show how most of Europe caught in the deep freeze is above the 45 deg. latitude line.  In the USA, you have to go just about to Michigan's UP to get that far North.  The weather that is crippling Europe is typical for a UP winter.  In other words, get used to it.

The long term outlook for Europe isn't very rosy.   These fierce deep freezes will become more common over the years, and this will result in arguments and political turmoil between Nations over the limited natural gas supply that comes from Russia.   Talk about a new cold war.

update:  There have been news stories blaming the historic cold spell on air currents and high pressure systems instead of on disruptions in the ocean current.  This is silly.  The mass of water in the oceans is some 250 times the mass of air in the atmosphere (1.3 E+21 kg versus 5 E+18 kg).  And because a pound of water can hold four times more heat than a pound of air can hold, the total heat capacity of the oceans is 1,000 times greater than the heat capacity of the atmosphere.  Weather patterns originate in the oceans, the atmosphere is just the messenger.    Saying that the atmosphere is driving the weather is like saying the little bird is driving the rhino.



  1. never stop pouring million Tm/year contamination to the foul air, they are almost suffocating in cities...and blame to the Anticyclone

  2. warming ("good" no longer spend cold)... pouring pollutants greenhouse effect into the air is melting the poles. Besides on melting permafrost will free into the Atmosphere million Tm of methane with big greenhouse effect. This large amount of freshwater to the ocean could stop (ThermoHaline Circulation) vertical deep sea currents which depend on starting in poles from surface ↓↓ downwards on a delicate balance between fresh and salty water and temperatures, and continuing go away slow and cold for the bottom loading nutrients and carrying large heat quantities. Deep sea currents move 90 % of all the oceans water. Heat from the Sun reaches the equator and currents distribute it throughout the Planet, then...goodbye to our warm climate. The horizontal oceanic currents on surface (move 10 % of all the oceans water) produced by winds, rotating (Gyres) all by the Coriolis effect, and some others in all levels by the rotation of the Earth from West → East, like the Antarctic circumpolar current, will continue...but the vertical currents produced by the sinking of horizontal currents of dense salty water that reaches the poles where the water is sweeter, less salty, and form cold bottom currents going heat transvasing between different latitudes would stop (why are the Grand Banks fishing in cold latitudes?...because over there is the POLAR ICE, freshwater, different sweet/salty density, salty dense water arriving and sinks in a little salty water environment...nutrients that are removed from the bottom cold water and rise to the surface, phytoplankton that feed on nutrients, zooplankton that feed on phytoplankton, fish that feed on zooplankton)... No polar ice over there will be no vertical currents...could reduce the rise of nutrients to the surface and therefore PHYTOPLANKTON SHORTAGE MAY DECREASING ITS VITAL CONTRIBUTION WITH OXYGEN TO THE ATMOSPHERE (90 %) in some places of more warm latitudes cary far the surface´s hot water permitting the outcropping ↑↑ to surface of water and plankton (the upwelling) from the bottom cold current coming from the pole, forming other Banks fishing, and returning on surface again like warm water towards the poles completing the THC circuit... Without polar ice the sea it could almost stratified into horizontal layers with little energetic movement of water masses in vertical which is what removes fertilizer nutrients from the bottom cold water, and also produces the THC... Besides lowering salinity of the sea, for that great contribution with freshwater to melt the poles, will increase evaporation (ebullioscopy: the less salt has, more evaporates) producing gigantic storm clouds as have never seen, that together with altering of the ocean currents, could cool areas of the Planet causing a new ice age... Warming...invasion of tropical diseases carried by their transmitter agents, already without the "general winter" stopping them would fall upon the World like a plague...can produce a cooling, a new ice age, like living at the North Pole...and less oxygen in the Atmosphere... Is not known to be worse... Go choosing.

  3. Meanwhile the World looks to elsewhere... Giant HORNETS...are threatening to all is necessary that the human beings, instead of destroy among them, destroy to those dangerous insects of huge exponential growing...seriously beginning already, at present.

  4. ...3D Bioprinting-Immortality (biological timers)... Forever young with modified Biological Timers...which are the biological timers?, where are them? (genes, hypothalamus...), how functioning them?, how can modify them (telomerase...) for maintenance the hormones production, enzymes, cellular regeneration...all Eternity at same level of the 18 years old?... Have to accelerate research about Memory and the Space´s Colonization... Immortality comes...

    1. Nobel Prize physiology 2017...about biological timers...
