They have to admit it now: Gulf Stream slowing - Sunday Times, May 8, 2005- Britain faces big chill as ocean current slows

CLIMATE change researchers have detected the first signs of a slowdown in the Gulf Stream, the mighty ocean current that keeps Britain and Europe from freezing.

They have found that one of the engines driving the Gulf Stream the sinking of supercooled water in the Greenland Sea, has weakened to less than a quarter of its former strength.

The weakening, apparently caused by global warming, could herald big changes in the current over the next few years or decades. Paradoxically, it could lead to Britain and northwestern and Europe undergoing a sharp drop in temperatures.

London's winters have already shown some cooling. If you remember the winter of '03-'04 saw the first snowstorm in hundreds of years.

But that's not all that will happen if the Atlantic Conveyor shuts down.

You know, it might just be time to put the global warming issue right up there with the War in Iraq as the major issues of the day.

what if? 08.May.2005 13:24

could this be the result of some sort of manipulation by elctromagnetic currents?

George Bender

Alder Fuller is currently teaching a class on Climate Change in Eugene. He teaches university level classes outside the educational system. Sliding scale tuition, no tests, grades, papers, credit, or other academic bullshit. What education ought to be. An excellent teacher, good at explaining complicated concepts. He'll be moving to Portland this summer and will be continuing his classes there.

His classes all relate to complexity, the science of complex systems. The earth's climate is a complex system. One scientist said that our climate is like an angry animal in a cage, "and we are poking it with a sharp stick." One of the characteristics of complex systems is that they are subject to sudden jumps, when stressed, from one stable state to a new one. This gives them the ability to adapt to change, but also makes them risky to fool with. If the earth's climate makes such a sudden jump, due to global warming caused by the carbon dioxide we're pumping into the atmosphere by burning fossile fuels, the new state may be one we can't live with. Literally.

interesting link for you

Very interesting possibility. I'm sure that they've thought of it, and they are doing their covert best to attempt to finagle this from behind the scenes to keep the sheeple from getting excited, which keeps themselves in power.

Title: Climate Change,Pentagon's Weather Nightmare,& ANDREW MARSHALL as OZ WIZARD OF 9-11
Author: various
Date: 2004.02.22 04:48
Description: It seems that Andrew Marshall is the strategist, while front men like Rumsfeld, Wolfowitz, Cheney, Bush, and others are amanuenses and factotums. In other words, Andrew Marshall is one of the people, like in the Wizard of Oz, of whom you are supposed to "pay no attention to the man behind the curtain." However, he is pulling the strings and the one making the plans--particularly the plans for the Pentagon's "transformation/revolution" in military affairs, that is moving the US military into a 'quick-global strike in-and-out' organization--using unmanned air vehicles and global satellite surveillance of all kinds. Notice his other concern: global environmental change. The public construction of the 9-11 events as "international terror" link up with the same networks of Marshallites that are concerned with global environmental change. The 9-11 story has provided them with their ONLY justification for the policies they want to implant across the world. Without 9-11, this Marshallite future would be dead on arrival. This is an article about Marshall, from information freely available around the net, with some commentary about connections and appointment in the Bush Administration that were in place for by 9-11-01.

<i>"could this be the result of some sort of manipulation by elctromagnetic currents?"</i>

No.

Or at any rate, it's not within the realm of power outputs available to our current civilization. As the article notes, the heat transferred just to Britain by the Atlantic Conveyor is about 27,000 times the British national power generation capacity. To influence it would presumably take an amount of power within a couple orders of magnitude of the conveyor's total heat transfer, and we're not even close to that capability.

A vast amount of industrial output that enables us to tap solar energy, continued over a long period of time, might do the trick though. Like, say, injecting enough greenhouse gasses into the atmosphere over a couple centuries to retain enough solar heat to partially melt the polar ice caps and change the salinity of the North Atlantic.

Ooops.

the film, Day After Tomorrow gets honourable mention! Recall how on its release, its science was howled at by the know-it-alls.

I think the complaints about that film's science had more to do with the imagined results of the shutdown than with the possibility of the shutdown itself. When people talk about abrupt climate change, they mean abrupt in geologic timeframes, not human timeframes. Such changes seem to happen over a decade or so... not a few days or weeks.

"the film, Day After Tomorrow gets honourable mention! Recall how on its release, its science was howled at by the know-it-alls."

The science in it pertaining to a possible North Atlantic Drift slowdown is OK .. just the timescale's condensed by orders of magnitude. In the film hours/days. In reality it will be decades. Also the whole bit about giant storms combining into a global superstorm ( for anyone who knows Meteorology ) is rubbish. In simple terms what goes up must come down and so there is always a system of high/low/high around the earth. As for the supercooling due to "cold air aloft being forced down" that is simply laughable. Basic gas law .... air descending compresses, causing heating. If the air had arrived at the surface at the same temperature it was at, say, 30,000ft, then that would have meant that the surface pressure would be 300mb ( around 1/3 atmosphere ) and we would all asphyxiate.
Still I enjoyed it as there was some decent characterization and special FX.
