All around the Pacific Basin, scientists have been collecting evidence that, between 12,000 and 5,000 years ago, El Nino was virtually nonexistent and that its reappearance coincided with great cultural changes. To illustrate, coral records from the western Pacific and sediments in the Great Lakes indicate that El Nino was going strong before 12,000 BP, but then there was an unexplained, 7,000-year lull. This lull is also seen clearly in sediments in Laguna Pallcacocha, a lake in the Andes of southern Ecuador, ... is El Nino's sudden resurgence around 5,000 BP. This resurgence and the associated worldwide climatic turmoil also marks the emergence of complex societies all over the planet. The Egyptians built pyramids, the Peruvians constructed temple mounds, civilizations rose and collapsed in the Middle East, and settled agrarian societies developed in many locations. Although not all cultures responded well to the climate changes, El Nino seems to have sparked the rise of modern civilizations. We are assuming that this was good!

It's the El Nino. El Nino is the name given the annual movement of warm water southward along the western coast of South America. Every few years (range 2-10 years, average about 3 years) this current penetrates much farther south, devastating the fishing industry. Usually the catastrophic El Ninos begin in the eastern Pacific and work westward. The current El Nino is out of phase somehow, beginning in the western Pacific and moving east. (The current extreme drought in Australia is part of this phenomenon.) The more powerful El Ninos are usually associated with severe ... in North America; the opposite is true this time. Obviously, something is amiss with the current El Nino. (Philander, S.G .H .; "El Nino Southern Oscillation Phenomena," Nature, 302:295, 1983.) Reference. Anomalous El Ninos are cataloged at GHT4 in Earthquakes, Tides. This book is described here . From Science Frontiers #27, MAY-JUN 1983 . 1983-2000 William R. Corliss ...

... Science Frontiers ONLINE No. 89: Sep-Oct 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects RHYTHMIC SUBMARINE VOLCANOS AND EL NINOS An El Nino commences when a giant high pressure system centered near Easter Island weakens slightly and causes a shift in the circulation of Pacific Ocean currents. Weather patterns from North America to Australia lurch ponderously in sympathy. El Ninos occur every 4-7 years, suggesting some periodic phenomenon is waving a geophysical baton. The real cause of El Ninos is still obscure. However, the recent discovery of over 1,000 previously unmapped submarine volcanos rising from the seafloor in the eastern Pacific may lead to El Nino's source. The synchronous eruption of, say, 100 of these volcanos might warm the ocean ... Easter Island a tad -- just enough to warm the atmosphere above a bit -- resulting in a shift of the high pressure area. The area of intense volcanic activity covers 55,000 square miles of sea floor where the Pacific and Nazca plates are separating. In addition to the active volcanos, many plumes of 800 F water gush from the sea floor in this area. The volcano-El Nino link is, therefore, not so far-fetched. (Nash, Nathaniel C.; "Volcano Group in Pacific May Cause El Nino," Pittsburgh Post Gazette, February 14, 1993. Cr. E. Fegert) Comment. If submarine volcanos do cause the El Ninos, and the El Ninos are periodic, the submarine volcanism would have to be periodic, too ...

... This information allowed them to better time the planting of potatoes -- their most important crop. The astronomical phenomenon they employed is far from obvious. The Pleiades are a cluster of bright stars in the constellation Taurus. The visibility of these stars varies slightly depending upon the amount of subvisual cirrus. If the Pleiades were dull in the month of June, the Andean farmers knew from experience that an El Nino was on the way. This betokened reduced rainfall and told them to postpone the planting of their potatoes by 4-6 weeks for best yields. The critical observations were made between June 13 and 24, when the Pleiades shine brightly just before dawn over the northeastern horizon. At this low angle, the presence of the subvisual cirrus has an obvious effect on the brightness of the stars ... the cluster, as indicated in the figure. Some of the lesser stars seem to disappear altogether. The visibility effect itself is rather subtle. It is remarkable enough that it was noticed at all by ancient peoples, much more so was their making the obscure connection to future weather. (Orlove, Benjamin S., et al; "Forecasting Andean Rainfall and Crop Yield from the Influence of El Nino on Pleiades Visibility," Nature, 403:68, 2000.) Comment. To the ancients, the Pleiades were known as the "seven sisters," be-cause their eyes registered seven resplendent stars. But today a naked-eye observer counts just six. What happened to the "Lost Pleiad?" Apparently it faded away in historical times. Details in AOF28 in ...

... "The observed "background" free oscillations represent some unknown dynamic process of Earth." Suda and his colleagues detected these oscillations using a superconducting gravimeter, which they installed in a seismically-quiet place: Antarctica. The favorite explanation for the background oscillations is turbulence in the earth's atmosphere. Ocean tides and currents are also on the list as potential "bell-ringers." [El Ninos were not mentioned!] (Suda, Naoki, et al; "Earth's Background Free Oscillations," Science, 279: 2089, 1998. Also: Kanamori, Hiroo; "Shaking without Quaking," Science, 279:2063, 1998.)
