The Beginning of the End

EXTREME WARNING
Key warming ocean current slowing down

By Jeremy Lovell

The Atlantic Conveyor, a life-giving ocean current that keeps northern Europe warm, is slowing down, scientists said on Wednesday.

If the 30 percent slowdown seen over the past 12 years is not just a blip, temperatures in northern Europe could drop significantly, despite global warming, they added.

Scientists have long forecast that the Atlantic Conveyor that carries warm surface water north and cold deep water back to the equator could break down because of global warming.

According to the theory, rising air temperatures cause ice caps to melt, making the water less salty and therefore less dense so it can't sink and flow back south.

The scientists on Wednesday said this was the first time that observations had put flesh on the bones of the theory.

"This is the first time we have observed a change in the current on a human timescale," oceanographer Harry Bryden said, noting that it had completely shut down during the ice ages.

But he said the latest figures were far from proving a trend and that constant and long-term monitoring was needed.

"It is like a radiator heating the atmosphere and is too important to leave to periodic observations," Bryden told a news conference to flesh out a paper he co-authored in Nature science journal.

FROM MOROCCO TO MIAMI

The Hadley Center for Climate Prediction and Research has calculated that if the current stopped, temperatures in northern Europe could drop by up to six degrees centigrade in 20 years.

The latest figures, collated last year, are from a string of monitoring devices at various depths in the Atlantic from Morocco to Miami.

It was the fifth snapshot since 1957 taken in the same area of the temperatures and currents in shallow, mid and deep ocean.

While measurements in 1981 and 1992 had shown little change, those in 1998 and 2004 had shown a major shift, with less of the warming Gulf Stream getting up to Greenland and less of the cold, deep returning current coming back.

The so-called Atlantic Meridional Overturning Current is known as the Atlantic Conveyor, of which the Gulf Stream is the surface component.

"This is tantalizing evidence that there may be a large change in ocean circulation under way that paradoxically could cause regional cooling," said Phil Newton of Britain's independent Natural Environment Research Council (NERC).

However, the scientists stressed that they could not be completely sure what was driving the change or how it might alter or be compensated for by winds that pick up the radiated heat and circulate it.

the Long Emergency

Most of all, the Long Emergency will require us to make other arrangements for the way we live in the United States. America is in a special predicament due to a set of unfortunate choices we made as a society in the twentieth century. Perhaps the worst was to let our towns and cities rot away and to replace them with suburbia, which had the additional side effect of trashing a lot of the best farmland in America.

Suburbia will come to be regarded as the greatest misallocation of resources in the history of the world. It has a tragic destiny. The psychology of previous investment suggests that we will defend our drive-in utopia long after it has become a terrible liability.

Before long, the suburbs will fail us in practical terms. We made the ongoing development of housing subdivisions, highway strips, fried-food shacks and shopping malls the basis of our economy, and when we have to stop making more of those things, the bottom will fall out.

The circumstances of the Long Emergency will require us to downscale and re-scale virtually everything we do and how we do it, from the kind of communities we physically inhabit to the way we grow our food to the way we work and trade the products of our work.

Our lives will become profoundly and intensely local. Daily life will be far less about mobility and much more about staying where you are. Anything organized on the large scale, whether it is government or a corporate business enterprise such as Wal-Mart, will wither as the cheap energy props that support bigness fall away. The turbulence of the Long Emergency will produce a lot of economic losers, and many of these will be members of an angry and aggrieved former middle class.

Food production is going to be an enormous problem in the Long Emergency. As industrial agriculture fails due to a scarcity of oil- and gas-based inputs, we will certainly have to grow more of our food closer to where we live, and do it on a smaller scale.

The American economy of the mid-twenty-first century may actually center on agriculture, not information, not high tech, not "services" like real estate sales or hawking cheeseburgers to tourists. Farming. This is no doubt a startling, radical idea, and it raises extremely difficult questions about the reallocation of land and the nature of work.

The relentless subdividing of land in the late twentieth century has destroyed the contiguity and integrity of the rural landscape in most places. The process of readjustment is apt to be disorderly and improvisational. Food production will necessarily be much more labor-intensive than it has been for decades. We can anticipate the re-formation of a native-born American farm-laboring class. It will be composed largely of the aforementioned economic losers who had to relinquish their grip on the American dream.

These masses of disentitled people may enter into quasi-feudal social relations with those who own land in exchange for food and physical security. But their sense of grievance will remain fresh, and if mistreated they may simply seize that land.

The way that commerce is currently organized in America will not survive far into the Long Emergency. Wal-Mart's "warehouse on wheels" won't be such a bargain in a non-cheap-oil economy.

The national chain stores' 12,000-mile manufacturing supply lines could easily be interrupted by military contests over oil and by internal conflict in the nations that have been supplying us with ultra-cheap manufactured goods, because they, too, will be struggling with similar issues of energy famine and all the disorders that go with it.

As these things occur, America will have to make other arrangements for the manufacture, distribution and sale of ordinary goods. They will probably be made on a "cottage industry" basis rather than the factory system we once had, since the scale of available energy will be much lower -- and we are not going to replay the twentieth century.

Tens of thousands of the common products we enjoy today, from paints to pharmaceuticals, are made out of oil. They will become increasingly scarce or unavailable. The selling of things will have to be reorganized at the local scale. It will have to be based on moving merchandise shorter distances. It is almost certain to result in higher costs for the things we buy and far fewer choices.

The automobile will be a diminished presence in our lives, to say the least. With gasoline in short supply, not to mention tax revenue, our roads will surely suffer. The interstate highway system is more delicate than the public realizes. If the "level of service" (as traffic engineers call it) is not maintained to the highest degree, problems multiply and escalate quickly. The system does not tolerate partial failure. The interstates are either in excellent condition, or they quickly fall apart.

America today has a railroad system that the Bulgarians would be ashamed of. Neither of the two major presidential candidates in 2004 mentioned railroads, but if we don't refurbish our rail system, then there may be no long-range travel or transport of goods at all a few decades from now.

The commercial aviation industry, already on its knees financially, is likely to vanish. The sheer cost of maintaining gigantic airports may not justify the operation of a much-reduced air-travel fleet. Railroads are far more energy efficient than cars, trucks or airplanes, and they can be run on anything from wood to electricity. The rail-bed infrastructure is also far more economical to maintain than our highway network.

The successful regions in the twenty-first century will be the ones surrounded by viable farming hinterlands that can reconstitute locally sustainable economies on an armature of civic cohesion. Small towns and smaller cities have better prospects than the big cities, which will probably have to contract substantially. The process will be painful and tumultuous.

In many American cities, such as Cleveland, Detroit and St. Louis, that process is already well advanced. Others have further to fall. New York and Chicago face extraordinary difficulties, being oversupplied with gigantic buildings out of scale with the reality of declining energy supplies. Their former agricultural hinterlands have long been paved over. They will be encysted in a surrounding fabric of necrotic suburbia that will only amplify and reinforce the cities' problems. Still, our cities occupy important sites. Some kind of urban entities will exist where they are in the future, but probably not the colossi of twentieth-century industrialism.

Some regions of the country will do better than others in the Long Emergency. The Southwest will suffer in proportion to the degree that it prospered during the cheap-oil blowout of the late twentieth century. I predict that Sunbelt states like Arizona and Nevada will become significantly depopulated, since the region will be short of water as well as gasoline and natural gas. Imagine Phoenix without cheap air conditioning.

I'm not optimistic about the Southeast, either, for different reasons. I think it will be subject to substantial levels of violence as the grievances of the formerly middle class boil over and collide with the delusions of Pentecostal Christian extremism. The latent encoded behavior of Southern culture includes an outsized notion of individualism and the belief that firearms ought to be used in the defense of it. This is a poor recipe for civic cohesion.

The Mountain States and Great Plains will face an array of problems, from poor farming potential to water shortages to population loss.

The Pacific Northwest, New England and the Upper Midwest have somewhat better prospects. I regard them as less likely to fall into lawlessness, anarchy or despotism and more likely to salvage the bits and pieces of our best social traditions and keep them in operation at some level.

These are daunting and even dreadful prospects. The Long Emergency is going to be a tremendous trauma for the human race. We will not believe that this is happening to us, that 200 years of modernity can be brought to its knees by a world-wide power shortage.

The survivors will have to cultivate a religion of hope -- that is, a deep and comprehensive belief that humanity is worth carrying on. If there is any positive side to stark changes coming our way, it may be in the benefits of close communal relations, of having to really work intimately (and physically) with our neighbors, to be part of an enterprise that really matters and to be fully engaged in meaningful social enactments instead of being merely entertained to avoid boredom.

Years from now, when we hear singing at all, we will hear ourselves, and we will sing with our whole hearts.

UPDATE:

Climate Has ‘Exceeded Crucial Threshold’
Earth's climate is undergoing an abrupt change, with the warming around Earth's tropical belt suggesting that the "climate system has exceeded a critical threshold", according to Lonnie Thompson, a scientist who has been taking core samples from the ice of glaciers for 23 years. As a result, Thompson says, the world may have to adapt more quickly than expected to rising temperatures, higher sea levels, and severe storms.
