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. Meaning of three sheets to the wind. Stabilizing our flip-flopping climate is not a simple matter. Although we can't do much about everyday weather, we may nonetheless be able to stabilize the climate enough to prevent an abrupt cooling. It has been called the Nordic Seas heat pump.
Its snout ran into the opposite side, blocking the fjord with an ice dam. But we may be able to do something to delay an abrupt cooling. Perhaps computer simulations will tell us that the only robust solutions are those that re-create the ocean currents of three million years ago, before the Isthmus of Panama closed off the express route for excess-salt disposal. Any meltwater coming in behind the dam stayed there. So freshwater blobs drift, sometimes causing major trouble, and Greenland floods thus have the potential to stop the enormous heat transfer that keeps the North Atlantic Current going strong. There seems to be no way of escaping the conclusion that global climate flips occur frequently and abruptly. The sheet in 3 sheets to the wind crossword puzzle. A lake surface cooling down in the autumn will eventually sink into the less-dense-because-warmer waters below, mixing things up. It's the high state that's good, and we may need to help prevent any sudden transition to the cold low state. And it sometimes changes its route dramatically, much as a bus route can be truncated into a shorter loop. This scenario does not require that the shortsighted be in charge, only that they have enough influence to put the relevant science agencies on starvation budgets and to send recommendations back for yet another commission report due five years hence. The same thing happens in the Labrador Sea between Canada and the southern tip of Greenland. Even the tropics cool down by about nine degrees during an abrupt cooling, and it is hard to imagine what in the past could have disturbed the whole earth's climate on this scale.
But our current warm-up, which started about 15, 000 years ago, began abruptly, with the temperature rising sharply while most of the ice was still present. The sheet in 3 sheets to the wind crossword clue. Unlike most ocean currents, the North Atlantic Current has a return loop that runs deep beneath the ocean surface. Oceanographers are busy studying present-day failures of annual flushing, which give some perspective on the catastrophic failures of the past. Obviously, local failures can occur without catastrophe—it's a question of how often and how widespread the failures are—but the present state of decline is not very reassuring. 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.
Or divert eastern-Greenland meltwater to the less sensitive north and west coasts. These northern ice sheets were as high as Greenland's mountains, obstacles sufficient to force the jet stream to make a detour. Oceans are not well mixed at any time. A brief, large flood of fresh water might nudge us toward an abrupt cooling even if the dilution were insignificant when averaged over time. 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. Fortunately, big parallel computers have proved useful for both global climate modeling and detailed modeling of ocean circulation. That's how our warm period might end too. The North Atlantic Current is certainly something big, with the flow of about a hundred Amazon Rivers. To stabilize our flip-flopping climate we'll need to identify all the important feedbacks that control climate and ocean currents—evaporation, the reflection of sunlight back into space, and so on—and then estimate their relative strengths and interactions in computer models. When there has been a lot of evaporation, surface waters are saltier than usual. N. London and Paris are close to the 49°N line that, west of the Great Lakes, separates the United States from Canada. By 1987 the geochemist Wallace Broecker, of Columbia University, was piecing together the paleoclimatic flip-flops with the salt-circulation story and warning that small nudges to our climate might produce "unpleasant surprises in the greenhouse. It would be especially nice to see another dozen major groups of scientists doing climate simulations, discovering the intervention mistakes as quickly as possible and learning from them.
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. This was posited in 1797 by the Anglo-American physicist Sir Benjamin Thompson (later known, after he moved to Bavaria, as Count Rumford of the Holy Roman Empire), who also posited that, if merely to compensate, there would have to be a warmer northbound current as well. When the ice cores demonstrated the abrupt onset of the Younger Dryas, researchers wanted to know how widespread this event was. History is full of withdrawals from knowledge-seeking, whether for reasons of fundamentalism, fatalism, or "government lite" economics. Ancient lakes near the Pacific coast of the United States, it turned out, show a shift to cold-weather plant species at roughly the time when the Younger Dryas was changing German pine forests into scrublands like those of modern Siberia. If blocked by ice dams, fjords make perfect reservoirs for meltwater.
Then not only Europe but also, to everyone's surprise, the rest of the world gets chilled. 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. 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. We need to make sure that no business-as-usual climate variation, such as an El Niño or the North Atlantic Oscillation, can push our climate onto the slippery slope and into an abrupt cooling. In the Greenland Sea over the 1980s salt sinking declined by 80 percent. 5 million years ago, which is also when the ape-sized hominid brain began to develop into a fully human one, four times as large and reorganized for language, music, and chains of inference. The fact that excess salt is flushed from surface waters has global implications, some of them recognized two centuries ago. There are a few obvious precursors to flushing failure. Up to this point in the story none of the broad conclusions is particularly speculative. 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.
And in the absence of a flushing mechanism to sink cooled surface waters and send them southward in the Atlantic, additional warm waters do not flow as far north to replenish the supply. Pollen cores are still a primary means of seeing what regional climates were doing, even though they suffer from poorer resolution than ice cores (worms churn the sediment, obscuring records of all but the longest-lasting temperature changes). "Southerly" Rome lies near the same latitude, 42°N, as "northerly" Chicago—and the most northerly major city in Asia is Beijing, near 40°. It's also clear that sufficient global warming could trigger an abrupt cooling in at least two ways—by increasing high-latitude rainfall or by melting Greenland's ice, both of which could put enough fresh water into the ocean surface to suppress flushing. This salty waterfall is more like thirty Amazon Rivers combined. In Greenland a given year's snowfall is compacted into ice during the ensuing years, trapping air bubbles, and so paleoclimate researchers have been able to glimpse ancient climates in some detail. We puzzle over oddities, such as the climate of Europe.
