Although I don't consider this scenario to be the most likely one, it is possible that solutions could turn out to be cheap and easy, and that another abrupt cooling isn't inevitable. The modern world is full of objects and systems that exhibit "bistable" modes, with thresholds for flipping. I call the colder one the "low state. " More rain falling in the northern oceans—exactly what is predicted as a result of global warming—could stop salt flushing. Judging from the duration of the last warm period, we are probably near the end of the current one. Twice a year they sink, carrying their load of atmospheric gases downward. Because such a cooling would occur too quickly for us to make readjustments in agricultural productivity and supply, it would be a potentially civilization-shattering affair, likely to cause an unprecedented population crash. When the warm currents penetrate farther than usual into the northern seas, they help to melt the sea ice that is reflecting a lot of sunlight back into space, and so the earth becomes warmer. We could go back to ice-age temperatures within a decade—and judging from recent discoveries, an abrupt cooling could be triggered by our current global-warming trend. Fjords are long, narrow canyons, little arms of the sea reaching many miles inland; they were carved by great glaciers when the sea level was lower. Our civilizations began to emerge right after the continental ice sheets melted about 10, 000 years ago. Or divert eastern-Greenland meltwater to the less sensitive north and west coasts. The sheet in 3 sheets to the wind crossword clue. Flying above the clouds often presents an interesting picture when there are mountains below. For a quarter century global-warming theorists have predicted that climate creep is going to occur and that we need to prevent greenhouse gases from warming things up, thereby raising the sea level, destroying habitats, intensifying storms, and forcing agricultural rearrangements.
It could no longer do so if it lost the extra warming from the North Atlantic. Although the sun's energy output does flicker slightly, the likeliest reason for these abrupt flips is an intermittent problem in the North Atlantic Ocean, one that seems to trigger a major rearrangement of atmospheric circulation. Recovery would be very slow. The sheet in 3 sheets to the wind crossword puzzles. We cannot avoid trouble by merely cutting down on our present warming trend, though that's an excellent place to start. Any abrupt switch in climate would also disrupt food-supply routes. Light switches abruptly change mode when nudged hard enough. Berlin is up at about 52°, Copenhagen and Moscow at about 56°.
Computer models might not yet be able to predict what will happen if we tamper with downwelling sites, but this problem doesn't seem insoluble. A cheap-fix scenario, such as building or bombing a dam, presumes that we know enough to prevent trouble, or to nip a developing problem in the bud. Salt sinking on such a grand scale in the Nordic Seas causes warm water to flow much farther north than it might otherwise do. Its effects are clearly global too, inasmuch as it is part of a long "salt conveyor" current that extends through the southern oceans into the Pacific. It was initially hoped that the abrupt warmings and coolings were just an oddity of Greenland's weather—but they have now been detected on a worldwide scale, and at about the same time. Because water vapor is the most powerful greenhouse gas, this decrease in average humidity would cool things globally. A lake formed, rising higher and higher—up to the height of an eight-story building. What is three sheets to the wind. Natural disasters such as hurricanes and earthquakes are less troubling than abrupt coolings for two reasons: they're short (the recovery period starts the next day) and they're local or regional (unaffected citizens can help the overwhelmed). Fatalism, in other words, might well be foolish. Abortive responses and rapid chattering between modes are common problems in nonlinear systems with not quite enough oomph—the reason that old fluorescent lights flicker. We must look at arriving sunlight and departing light and heat, not merely regional shifts on earth, to account for changes in the temperature balance.
This warm water then flows up the Norwegian coast, with a westward branch warming Greenland's tip, at 60°N. A quick fix, such as bombing an ice dam, might then be possible. Now only Greenland's ice remains, but the abrupt cooling in the last warm period shows that a flip can occur in situations much like the present one. Sudden onset, sudden recovery—this is why I use the word "flip-flop" to describe these climate changes. Once the dam is breached, the rushing waters erode an ever wider and deeper path. There is also a great deal of unsalted water in Greenland's glaciers, just uphill from the major salt sinks. They are utterly unlike the changes that one would expect from accumulating carbon dioxide or the setting adrift of ice shelves from Antarctica. Though combating global warming is obviously on the agenda for preventing a cold flip, we could easily be blindsided by stability problems if we allow global warming per se to remain the main focus of our climate-change efforts. Of this much we're sure: global climate flip-flops have frequently happened in the past, and they're likely to happen again. Door latches suddenly give way.
The system allows for large urban populations in the best of times, but not in the case of widespread disruptions. All we would need to do is open a channel through the ice dam with explosives before dangerous levels of water built up. A nice little Amazon-sized waterfall flows over the ridge that connects Spain with Morocco, 800 feet below the surface of the strait. I hope never to see a failure of the northernmost loop of the North Atlantic Current, because the result would be a population crash that would take much of civilization with it, all within a decade. The back and forth of the ice started 2. What could possibly halt the salt-conveyor belt that brings tropical heat so much farther north and limits the formation of ice sheets? Whereas the familiar consequences of global warming will force expensive but gradual adjustments, the abrupt cooling promoted by man-made warming looks like a particularly efficient means of committing mass suicide. But the ice ages aren't what they used to be.
By 1961 the oceanographer Henry Stommel, of the Woods Hole Oceanographic Institution, in Massachusetts, was beginning to worry that these warming currents might stop flowing if too much fresh water was added to the surface of the northern seas. One is diminished wind chill, when winds aren't as strong as usual, or as cold, or as dry—as is the case in the Labrador Sea during the North Atlantic Oscillation. The discovery of abrupt climate changes has been spread out over the past fifteen years, and is well known to readers of major scientific journals such as Scienceand abruptness data are convincing. Volcanos spew sulfates, as do our own smokestacks, and these reflect some sunlight back into space, particularly over the North Atlantic and Europe. Timing could be everything, given the delayed effects from inch-per-second circulation patterns, but that, too, potentially has a low-tech solution: build dams across the major fjord systems and hold back the meltwater at critical times. Perish in the act: Those who will not act. But the regional record is poorly understood, and I know at least one reason why. The Atlantic would be even saltier if it didn't mix with the Pacific, in long, loopy currents. In 1970 it arrived in the Labrador Sea, where it prevented the usual salt sinking. There is, increasingly, international cooperation in response to catastrophe—but no country is going to be able to rely on a stored agricultural surplus for even a year, and any country will be reluctant to give away part of its surplus. Paleoclimatic records reveal that any notion we may once have had that the climate will remain the same unless pollution changes it is wishful thinking. Within the ice sheets of Greenland are annual layers that provide a record of the gases present in the atmosphere and indicate the changes in air temperature over the past 250, 000 years—the period of the last two major ice ages. A meteor strike that killed most of the population in a month would not be as serious as an abrupt cooling that eventually killed just as many. There used to be a tropical shortcut, an express route from Atlantic to Pacific, but continental drift connected North America to South America about three million years ago, damming up the easy route for disposing of excess salt.
We must be careful not to think of an abrupt cooling in response to global warming as just another self-regulatory device, a control system for cooling things down when it gets too hot. We can design for that in computer models of climate, just as architects design earthquake-resistant skyscrapers. The last abrupt cooling, the Younger Dryas, drastically altered Europe's climate as far east as Ukraine. It's the high state that's good, and we may need to help prevent any sudden transition to the cold low state. Those who will not reason. Thermostats tend to activate heating or cooling mechanisms abruptly—also an example of a system that pushes back.
For example, I can imagine that ocean currents carrying more warm surface waters north or south from the equatorial regions might, in consequence, cool the Equator somewhat. At the same time that the Labrador Sea gets a lessening of the strong winds that aid salt sinking, Europe gets particularly cold winters. A lake surface cooling down in the autumn will eventually sink into the less-dense-because-warmer waters below, mixing things up. Though some abrupt coolings are likely to have been associated with events in the Canadian ice sheet, the abrupt cooling in the previous warm period, 122, 000 years ago, which has now been detected even in the tropics, shows that flips are not restricted to icy periods; they can also interrupt warm periods like the present one. By 125, 000 years ago Homo sapienshad evolved from our ancestor species—so the whiplash climate changes of the last ice age affected people much like us. By 250, 000 years ago Homo erectushad died out, after a run of almost two million years. The effects of an abrupt cold last for centuries. With the population crash spread out over a decade, there would be ample opportunity for civilization's institutions to be torn apart and for hatreds to build, as armies tried to grab remaining resources simply to feed the people in their own countries. Rather than a vigorous program of studying regional climatic change, we see the shortsighted preaching of cheaper government at any cost. It, too, has a salty waterfall, which pours the hypersaline bottom waters of the Nordic Seas (the Greenland Sea and the Norwegian Sea) south into the lower levels of the North Atlantic Ocean. Glaciers pushing out into the ocean usually break off in chunks. The U. S. Geological Survey took old lake-bed cores out of storage and re-examined them. Oslo is nearly at 60°N, as are Stockholm, Helsinki, and St. Petersburg; continue due east and you'll encounter Anchorage. We are near the end of a warm period in any event; ice ages return even without human influences on climate.
These northern ice sheets were as high as Greenland's mountains, obstacles sufficient to force the jet stream to make a detour. There seems to be no way of escaping the conclusion that global climate flips occur frequently and abruptly. Instead we would try one thing after another, creating a patchwork of solutions that might hold for another few decades, allowing the search for a better stabilizing mechanism to continue. Broecker has written, "If you wanted to cool the planet by 5°C [9°F] and could magically alter the water-vapor content of the atmosphere, a 30 percent decrease would do the job. Things had been warming up, and half the ice sheets covering Europe and Canada had already melted. We might, for example, anchor bargeloads of evaporation-enhancing surfactants (used in the southwest corner of the Dead Sea to speed potash production) upwind from critical downwelling sites, letting winds spread them over the ocean surface all winter, just to ensure later flushing.
Surface waters are flushed regularly, even in lakes. Greenland looks like that, even on a cloudless day—but the great white mass between the occasional punctuations is an ice sheet.
