Perish in the act: Those who will not act. Meaning of three sheets to the wind. When there has been a lot of evaporation, surface waters are saltier than usual. We are near the end of a warm period in any event; ice ages return even without human influences on climate. 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. But sometimes a glacial surge will act like an avalanche that blocks a road, as happened when Alaska's Hubbard glacier surged into the Russell fjord in May of 1986.
That increased quantities of greenhouse gases will lead to global warming is as solid a scientific prediction as can be found, but other things influence climate too, and some people try to escape confronting the consequences of our pumping more and more greenhouse gases into the atmosphere by supposing that something will come along miraculously to counteract them. The Mediterranean waters flowing out of the bottom of the Strait of Gibraltar into the Atlantic Ocean are about 10 percent saltier than the ocean's average, and so they sink into the depths of the Atlantic. And it sometimes changes its route dramatically, much as a bus route can be truncated into a shorter loop. 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. Just as an El Niño produces a hotter Equator in the Pacific Ocean and generates more atmospheric convection, so there might be a subnormal mode that decreases heat, convection, and evaporation. 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. Increasing amounts of sea ice and clouds could reflect more sunlight back into space, but the geochemist Wallace Broecker suggests that a major greenhouse gas is disturbed by the failure of the salt conveyor, and that this affects the amount of heat retained. The sheet in 3 sheets to the wind crossword clue. There is another part of the world with the same good soil, within the same latitudinal band, which we can use for a quick comparison.
N. London and Paris are close to the 49°N line that, west of the Great Lakes, separates the United States from Canada. To the long list of predicted consequences of global warming—stronger storms, methane release, habitat changes, ice-sheet melting, rising seas, stronger El Niños, killer heat waves—we must now add an abrupt, catastrophic cooling. Then not only Europe but also, to everyone's surprise, the rest of the world gets chilled. 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. The saying three sheets to the wind. When this happens, something big, with worldwide connections, must be switching into a new mode of operation.
The fjords of Greenland offer some dramatic examples of the possibilities for freshwater floods. The better-organized countries would attempt to use their armies, before they fell apart entirely, to take over countries with significant remaining resources, driving out or starving their inhabitants if not using modern weapons to accomplish the same end: eliminating competitors for the remaining food. Light switches abruptly change mode when nudged hard enough. Present-day Europe has more than 650 million people. 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. 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. Of this much we're sure: global climate flip-flops have frequently happened in the past, and they're likely to happen again. Medieval cathedral builders learned from their design mistakes over the centuries, and their undertakings were a far larger drain on the economic resources and people power of their day than anything yet discussed for stabilizing the climate in the twenty-first century. We need more well-trained people, bigger computers, more coring of the ocean floor and silted-up lakes, more ships to drag instrument packages through the depths, more instrumented buoys to study critical sites in detail, more satellites measuring regional variations in the sea surface, and perhaps some small-scale trial runs of interventions. But to address how all these nonlinear mechanisms fit together—and what we might do to stabilize the climate—will require some speculation.
Nothing like this happens in the Pacific Ocean, but the Pacific is nonetheless affected, because the sink in the Nordic Seas is part of a vast worldwide salt-conveyor belt. 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. 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. Keeping the present climate from falling back into the low state will in any case be a lot easier than trying to reverse such a change after it has occurred. It could no longer do so if it lost the extra warming from the North Atlantic. Unlike most ocean currents, the North Atlantic Current has a return loop that runs deep beneath the ocean surface.
The high state of climate seems to involve ocean currents that deliver an extraordinary amount of heat to the vicinity of Iceland and Norway. Such a conveyor is needed because the Atlantic is saltier than the Pacific (the Pacific has twice as much water with which to dilute the salt carried in from rivers). But we may not have centuries for acquiring wisdom, and it would be wise to compress our learning into the years immediately ahead. Further investigation might lead to revisions in such mechanistic explanations, but the result of adding fresh water to the ocean surface is pretty standard physics. 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. Europe's climate could become more like Siberia's. Any meltwater coming in behind the dam stayed there. Those who will not reason. In 1970 it arrived in the Labrador Sea, where it prevented the usual salt sinking. For Europe to be as agriculturally productive as it is (it supports more than twice the population of the United States and Canada), all those cold, dry winds that blow eastward across the North Atlantic from Canada must somehow be warmed up.
To keep a bistable system firmly in one state or the other, it should be kept away from the transition threshold. Plummeting crop yields would cause some powerful countries to try to take over their neighbors or distant lands—if only because their armies, unpaid and lacking food, would go marauding, both at home and across the borders. In places this frozen fresh water descends from the highlands in a wavy staircase. A remarkable amount of specious reasoning is often encountered when we contemplate reducing carbon-dioxide emissions. Like a half-beaten cake mix, with strands of egg still visible, the ocean has a lot of blobs and streams within it. Yet another precursor, as Henry Stommel suggested in 1961, would be the addition of fresh water to the ocean surface, diluting the salt-heavy surface waters before they became unstable enough to start sinking. One of the most shocking scientific realizations of all time has slowly been dawning on us: the earth's climate does great flip-flops every few thousand years, and with breathtaking speed.
It has been called the Nordic Seas heat pump. This cold period, known as the Younger Dryas, is named for the pollen of a tundra flower that turned up in a lake bed in Denmark when it shouldn't have. A brief, large flood of fresh water might nudge us toward an abrupt cooling even if the dilution were insignificant when averaged over time. We can design for that in computer models of climate, just as architects design earthquake-resistant skyscrapers. Eventually such ice dams break, with spectacular results. In the Greenland Sea over the 1980s salt sinking declined by 80 percent. They might not be the end of Homo sapiens—written knowledge and elementary education might well endure—but the world after such a population crash would certainly be full of despotic governments that hated their neighbors because of recent atrocities.
Perish for that reason. But the ice ages aren't what they used to be. In 1984, when I first heard about the startling news from the ice cores, the implications were unclear—there seemed to be other ways of interpreting the data from Greenland. Fortunately, big parallel computers have proved useful for both global climate modeling and detailed modeling of ocean circulation. History is full of withdrawals from knowledge-seeking, whether for reasons of fundamentalism, fatalism, or "government lite" economics. It keeps northern Europe about nine to eighteen degrees warmer in the winter than comparable latitudes elsewhere—except when it fails. Things had been warming up, and half the ice sheets covering Europe and Canada had already melted. Salt circulates, because evaporation up north causes it to sink and be carried south by deep currents. Door latches suddenly give way. 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. In Broecker's view, failures of salt flushing cause a worldwide rearrangement of ocean currents, resulting in—and this is the speculative part—less evaporation from the tropics. Greenland's east coast has a profusion of fjords between 70°N and 80°N, including one that is the world's biggest. Temperature records suggest that there is some grand mechanism underlying all of this, and that it has two major states.
Its snout ran into the opposite side, blocking the fjord with an ice dam.
