The extra cold weather is a symptom of global warming. What it means is the gulf stream is breaking down and is no longer providing warmth to Europe.
Here is a link and quote from :
"A special study was conducted through one of the Pentagon’s departments, the Office of Net Assessment, which is directed by Andrew W. Marshall,
83, who has the responsibility of identifying long-term threats to the United States."
"Mr. Marshall went to a US based think-tank called Global Business Network to compile the possibilities of Global Warming on US national security. A
study was completed in October of 2003 and released to the Pentagon, which was looking at this problem from the point of view of what is the worst
that could happen. It was named “An Abrupt Climate Change Scenario and Its Implications for United States National Security.” The summary went far
beyond what most Pentagon experts had expected."
"Realizing the incredible possibilities of this study, Mr. Marshall made a decision to publicly report this and other information to the American
people. And probably because of President Bush’s stance on Global Warming, which is beyond negative, he also decided to go around the president, and
he published his information and concern in Fortune magazine on February 9th 2004."
"In his article in Fortune, Mr. Marshall explains how the melting North and South poles and glaciers from around the world are composed of fresh
water and within this fact is the basis of the impending global weather disaster."
"The Gulf Stream or scientifically referred to as North Atlantic thermohaline conveyor is a stream of warm water that comes from south of the equator
and flows over the surface of the ocean toward the north where this warm water keeps Northern America and Northern and Western Europe from freezing.
It also holds most of the world’s weather patterns in the way we are used to."
"Then as this Gulf Stream cools down, it drops to the bottom of the ocean and returns as a river in the ocean to the south where it warms up again
and rises to the surface and then returns to the north one more time in a continuous convection current. It is a huge three dimensional figure
"The motor that keep this warm water flowing is found in the north where the Gulf Stream drops to the bottom of the ocean. It is the salt density of
the ocean that causes this river to drop and pulls the warm water up from the south."
"Now that the poles are melting and fresh water is flowing into the Atlantic Ocean and the salt density is decreasing, the Gulf Stream does not drop
quiet as far, which results in a slowing down of this Stream. The Gulf Stream has been dramatically slowing down now for at least ten years."
"As the Gulf Stream slows down, the warmth is not brought to the North Atlantic region, and the weather patterns begin to change for they are
dependent on this warmth to keep a balance."
Global warming appears to be happening. My personal belief is that although man has contributed to global warming, the real cause is just another part
of a natural occurring earth cycle. Possibly a cycle that goes beyond earth and is affecting the whole solar system. If the gulf stream is breaking
down we are in big trouble.
