About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.

Their trace impurities are believed to accurately record the earth's climate over the last several hundred thousand years. The temporal accuracy of this record is based upon the assumption that these impurities have not migrated vertically from where they were deposited. This assumption is now under severe stress with the discovery of anomalous diffusion within ice plus a phase phenomenon called "premelting," both of which result in the transport of the climate-marking impurities far from their original layer of deposition. A.W . Rempel et al write below (in the jargon of climatologists): .. .under conditions that resemble those encountered in the Eemian interglacial ice of central Greenland (from about 125,000 to 115,000 years ago---impurity fluctuations may be separated from ice of the same age by as much as 50 cm. This distance is comparable to the ice thickness of the contested sudden cooling events in the Eemian ice from the GRIP core. Translation: The accepted picture of the earth's climate history over the last few hundred thousand years may be seriously distorted.

"The researchers detected chemical signs of bacteria and algae in known and suspected dinosaur droppings. That indicates that plant-eating dinosaurs digested their food by fermenting it, a process that gives off methane." We all know that methane is a "greenhouse gas," so it seems that the dinosaurs may have self-destructed. (Anonymous; "How Dinosaurs May Have Helped Make Earth Warmer," San Francisco Chronicle, October 23, 1991. Cr. D.H . Palmer) Comment. We are not being facetious here, for it is seriously proposed that much of the greenhouse gas produced today comes from cattle, sheep, and other animals that ferment their food.

"Past values for the geomagnetic intensity may be obtained by laboratory analysis of the thermoremanent magnetization carried by clay baked in ancient times. From global averages of such determinations it is commonly accepted that the intensity in any given region went through a broad maximum about 2000 years ago, reaching a level about 50% higher than at present. Here we present results obtained from a wide range of Chinese pottery, spanning the interval from 4000 BC to the present, indicating that the field behaviour was more complex. The intensity was high between 1500 and 1000 BC and again in the first half of the first millennium AD. Comparison with results reported for Western Asia, Egypt and Crete suggests that these high values are due to non-dipole disturbances in the geomagnetic field, consistent with long-term records of the cosmogenic radioisotopes 14C and 10Be." (Quing-Yun, Wei, et al; "Geomagnetic Intensity as Evaluated from Ancient Chinese Pottery," Nature, 328:330, 1987.) Comment. This article stimulates three questions: What caused the geomagnetic changes; could some be of internal origin? Are periods of reduced magnetic fields associated with cultural changes? The graph, for example, reveals a dip during the flowering of Greek civilization. Could such ambient magnetic changes have an effect on human imagination, as reported in laboratory test?. See SF# ...

(SF#110) The media have said little about the staggering quantities of methane and higher hydrocarbons locked up in frozen hydrates around the edges of the continents. Actually, the small methane burps are minor problems compared to the catastrophic climate changes that could be forced if just a small portion of the gases frozen under the sea floor were released into the atmosphere. Gas-hydrates are unimpressive when brought to the surface -- just dirty, fizzy ice. However, taken together, they contain more carbon than all the world's oil fields, perhaps much more. Most estimates fall between 1,700 and 11,000 billion tons, but there is one scientist who pegs these cold-storage carbon deposits at 4,100,000 billion tons. In comparison, human releases of carbon to the atmosphere via the burning of wood, gas, coal, and even the collective flatulence of all the planet's animals are trivial. Geological evidence confirms that past climate swings were associated with large injections of carbon into the atmosphere and oceans. A major contributor to these "carbon burps" may be decomposing methane hydrate. Until recently, climatologists have questioned the sizes of gas-hydrate deposits, but cores extracted from the Blake Ridge off the Carolina coast confirm ...

The search has revealed that at six times during the last glaciation, huge armadas of icebergs launched from Canada spread across the northern Atlantic Ocean, each triggering a climate response of global extent." The foregoing abstract does not mention the interesting Heinrich layers that fostered the above scenario. In 1988, H. Heinrich published a paper describing a curious set of sedimentary layers found in cores drilled in the tops of the Dreizack seamounts in the eastern North Atlantic. Heinrich concluded that each of the six layers he found represented the melting of "six great armadas of icebergs." These icebergs carried debris picked up in Canada and, as they melted, deposited it on the seamounts and ocean floor. Each layer could be correlated with the major climate boundaries revealed by the Greenland ice cores. Very fittingly, these iceberg incursions are now termed "Heinrich Events."

Numerous leaves of the seed fern Glossopteris are present in the shale in which the trunks are rooted. The trunks are perminealized and tree rings reveal that the forest was a rapidly growing and young forest, persisting in an equable, strongly seasonal climate -- a scenario that does not fit with some climate reconstructions for this time period." Some models of the Permian climate, based on astronomical and meteorological parameters, have winter temperatures at the site averaging -30 to -40 C, with the average summer temperature at merely 0 C. This fossil forest is clearly at odds with these models. (Taylor, Edith L., et al; "The Present Is Not the Key to the Past: A Polar Forest from the Permian of Antarctica," Science, 257:1675, 1992.)

The sunspot cycle can be seen in variations of varves; i.e ., annual layers of sediment; and the growth rings of shells have been used to estimate the number of days in the lunar month when the solar system was younger. Cyclothems may also be useful. Cyclothems are groups or bundles of strata that repeat themselves in stratigraphic columns. A generalized cyclothem from Illinois is shown in the illustration. In the U.S . western interior, rhythmic sedimentation appears in the Fort Hays Limestone Member of the Niobrara Formation. These cyclothems can be correlated over distances exceeding 800 kilometers and are believed to be the consequence of climatic changes associated with the earth's precession and orbital eccentriciy. These rhythms have been captured in bundles of shale-limestone couplets. A bundle of five coup lets, for example, is thought to express 21,000- and 100,000-year Milankovitchtype climatic cycles, as impressed by variations in the earth's orbital precession and eccentricity. Analysis of the Fort Hays Limestone Member, however, reveals that while bundles of five couplets do occur, the number may vary from 1 to 12. Clearly, things are not clear-cut.

Science Frontiers ONLINE No. 130: JUL-AUG 2000 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Bog Breath Yes, bogs do breathe albeit rather erratically. The slow heaving of their surfaces is a poorly understood phenomenon as the following abstract demonstrates. The surfaces of bogs and fens in northeastern Minnesota may rise and fall by as much as 36 cm in a single day. This phenomenon, known as Mooratmung, or bog breathing, has been traditionally attributed to changes in water storage. However, the surface deformations recorded by static GPS [Global Positioning System] stations on bog and fen sites within the Red Lake peatland are more frequent and out of phase with precipitation events. These vertical fluctuations instead appear to be related to a complex interplay among climate, hydrology, and microbial gas-production. Climate-driven re-charge on bogs, for example, stimulates the production of biogenic gases by advecting root exudates deep into the peat profiles. Seasonal droughts, however, favor the formation of transient confining layers that trap biogenic gases into discrete pockets... Bog breathing may therefore be a surface manifestation of the accumulation and release of greenhouse gases in peat deposits. (Glaser, Paul H. et al; "Bog Breathing: the Curious Interplay of Climate, Ground-water, and Greenhouse Gases in Boreal Peatlands," Eos, 80:F47, 1999.) Spontaneously igniting, biogenic gases are found in many marshy places. These eruptions were observed on an English mud flat in 1902. Comment. When bogs breathe they ...

... Subjects Of Dust Clouds And Ice Ages Ice cores from the polar ice at Camp Century, in Greenland, have been analyzed for the presence of cosmic dust. "It is concluded that on five occasions during the interval 20,000-14,000 years BP, cosmic dust mass concentrations in the solar system rose by one and two orders of magnitude above present day levels. Moreover if the particles found in these ice core samples are indicative of the particle size distribution which prevailed in the interplanetary medium at that time, then it may be concluded that the space number density of submicron sized particles must have uncreased by a factor of 105 or more. During these times the light transmission properties of the solar system would have been significantly altered resulting in major adverse effects to the earth's climate. Thus it is quite possible that these dust congestion episodes were responsible for the abrupt climatic variations which occurred toward the end of the last Ice Age." Whence these interplanetary dust clouds? The author of this article ruled out terrestrial volcanism (an insufficient source of iridium) and encounters with asteroids and cometary tails (too infrequent to account for the long periods of high dust levels). Rather, the dust source may have been the same event that created the recently discovered dust ring between Mars and Jupiter, which is believed to be only a few tens of thousands of years old. The nature of the "event" is not specified. (LaViolette, Paul A.; "Evidence of High Cosmic Dust Concentrations in Late Pleistocene Polar Ice (20,000-14, ...

Hapgood in 1958. He also wrote The Path of the Pole (1970). Several other authors have also proposed that sudden slippages of the earth's crust caused wild climate fluctuations in the past with devastating biological consequences -- in particular, all those quickfrozen mammoths in Siberia. These poleshift scenarios coming from thinkers swimming far out of the scientific mainstream have been studiously ignored in a "new" and well-publicized pole-shift theory recently appearing in Science. The "new" theory relates to an old (534-millionyears-ago) crustal slippage, whereas Hapgood was talking about a cataclysm within the last 10,000 years or so. Nevertheless, it would have been nice to see Hapgood's earlier work acknowledged. Four features of this "new" proposal make it more palatable than Hapgood's to today's geologists and geophysicists: Two of the "new" authors, J. Kirschvink and D.A . Evans, are at the prestigious California Institute of Technology, while Hapgood was a PhD-less history professor at Keene State College. Status is important when theorizing.

They visualize a huge chunk of the seafloor suddenly foundering and thereby changing the planet's mass distribution. This imbalance caused ...

Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Recent Pulsations Of Life At a recent meeting of scientists at the Lamont-Doherty Geological Observatory, E. Vrba, of the Transvaal Museum, in Pretoria, stated: "If we eventually are able to establish a good time resolution with the continental record, I expect to be able to discern synchronous pulses of evolution that involve many groups of fauna and flora. Many different lineages in the biota will respond by synchronous waves of speciation and extinction to global temperature extremes and attendant environmental changes. This is my starting hypothesis." Vrba was speaking mainly about the last 25 million years, a mere flash in geological time. For this brief period, the Deep Sea Drilling Program has provided geologists with a detailed and continuous record of climate changes as they were recorded in deep-sea sediments. By contrast, the faunal history of the continents is rather fragmentary, making it rather difficult to match up pulsations of climate with pulsations of life. Even so, scientists have found rather strong correlations between climatary change and biological speciation and extinction at 15, 5, and 2.4 million years ago. (Lewin, Roger; "The Paleoclimatic Magic Numbers Game," Science, 226:154, 1984.) Comment. Note that this is just the period our ancestors seemed to be evolving rapidly. Also interesting is the general agreement between Vrba's statement about the driving forces behind evolution and McClintock's conclusion quoted earlier under BIOLOGY.

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, so 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!

... Sourcebook Subjects The Night Of The Polar Dinosaur Somewhere west of Deadhorse, a small town on Prudhoe Bay in northern Alaska, paleontologists have found the bones of at least three species of dinosaurs. But wait, the latitude there is 70 north today and according to magnetic measurements of the rocks, it was about the same when the dinosaurs met their demise. At these high latitudes the dinosaurs either had to contend with two months of darkness each year or they had to migrate many hundreds of miles over the rough Alaskan landscape. The visions of dinosaurs groping for tons of vegetable food in the polar night is about as incongruous as imagining them trekking down to the Lower 481 Scientists are now maintaining that these dinosaurs did prosper on the shore of the Arctic Ocean, even in the dark, because the climate then was semitropical or temperate. This was because the earth's climate was more equable or uniform. They are, however, surprised by the lack of mineral deposition in the dinosaur bones, which look rather "mode m".

... is indeed striking: a collection of chipped and flaked rocks that are clearly artifacts fashioned by humanlike hands and that he contends are 2.5 million years old -- plus or minus a half-million years. "Remarkably, that same era marked the time when early human ancestors known as Homo habilis lived and left their remains in the tropical Olduvai Gorge of what is now Tanzania. Mochanov's collection of tools closely resembles the ones that anthropologists have long collected from digs in Africa." All this contrasts strongly with the dominant view of hominid evolution, which cites warm, verdant African forests and savannas as our most likely place of origin. Siberia, with its -50 winters and fleeting summers, hardly seems conducive to hominid speciation. Mochanov's rationale is that this severe climate actually stimulated ancient hominids to create tools, fashion warm clothing, and build winter shelters -- these Siberian hominids had to evolve or perish! In addition to the climate factor are two other problems: (1 ) The Siberian sites have yielded no hominid bones nor have animal bones of any kind been found; and (2 ) The dating of the tools is shaky. They cannot be radiometrically dated. Instead, Mochanov has had to rely on the tools' similarity to African tools of 2 million years ago, magnetostratigraphy, the decayed luminescence of the soil, and the ages of the strata in the 450-foot gorge of the Lena River. It goes without saying that other anthropologists are reserving judgment. Nevertheless, Mochanov's Siberian discoveries have produced a magnitude-8 tremor ...

Science Frontiers ONLINE No. 34: Jul-Aug 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Behind magnetic flip-flops The earth's magnetic field frequently reverses its polarity. Such flips can of-ten be correlated with climate changes, global ice volumes, sea-floor spreading rates, and deposition of black shales, tektite falls, biological extinctions, etc. The frustrating thing is the lack of clear-cut cause and effect; that is, how these phenomena are linked physically to the geomagnetic field. Part of the problem is that we can only guess at how the geomagnetic field is generated. Let us assume that the earth's magnetic field is created by dynamo action in the planet's fluid core. P. Olson finds analytically that the core dynamo may reverse sign due to fluctuations in core turbulence caused by two competing energy sources: heat loss at the mantle-core boundary and progressive growth of the inner core. In concept, the heat lost at the core-mantle boundary might be linked to climate changes and sea-floor spreading. Taking a different tack, D. Gubbins has investigated the possibility that field reversals are triggered by ice ages and meteorite impacts (tektite falls). The physical mechanism here would be the increase in pressure upon the core, which affects the rate of freezing in the outer core, and thus the power available to the core dynamo. Gubbins found that these externally caused pressure changes were too small to explain the polarity changes. However, the parameters involved ...

... tell us that the volcanic sources are grossly inadequate. So are all other possible terrestrial sources. Therefore, some scientists, such as D. Deming, University of Oklahoma, have been looking spaceward. Deming ventures that extraterrestrial sources of water and carbon may be four or five orders of magnitude greater than suspected. Obviously, a steady bombardment of icy comets might fulfill Deming's requirements. Down the long eons of geological time, they could have filled the oceans and showered all that excess carbon onto the planet's surface. Deming ups the stakes in the icy-comet controversy when he links these fluffy snowballs to the well-known vagaries of life on earth. "The extraterrestrial influx rate may also act as the pacemaker of terrestrial evolution, at times leading to mass extinctions through climatic shifts induced by changes in accretion rates with concommitant disruptions of the carbon and nitrogen cycles. Life on earth may be balanced precariously between cosmic processes which deliver an intermittent stream of life-sustaining volatiles from the outer solar system or beyond, and biological and tectonic processes which remove these same volatiles from the atmosphere by sequestering water and carbon in the crust and mantle."

Muller and D.E . Morris review the evidence tying geomagnetic reversals to the impacts of large bodies with the earth: the tektites and microtektites; the climate changes; the biological extinctions, etc. Then they propose a physical mechanism for geomagnetic reversals: "The impact of a large extraterrestrial object on the Earth can produce a geomagnetic reversal through the following mechanism: dust from the impact crater and soot from fires trigger a climate change and the beginning of a little ice age. The redistribution of water near the equator to ice at high latitudes alters the rotation rate of the crust and mantle of the Earth. If the sea-level change is sufficiently large ( 10 meters) and rapid (in a few hundred years), then the velocity shear in the liquid core disrupts the convective cells that drive the dynamo. The new convective cells that subsequently form distort and tangle the previous field, reducing the dipole component near to zero while increasing the energy in multipole components. Eventually a dipole is rebuilt by dynamo action, and the event is seen either as a geomagnetic reversal or as an excursion."

But now, Russian scientist A. Sher and two colleagues claim that a dwarf version of the wooly mammoth survived on Wrangel Island, 120 miles off the Siberian coast until about 3,700 years ago. The Wrangel Island dwarf mammoths stood only about 2 meters high and weighed 2 tons. The British mammoth expert, A. Lister, said he was not really surprised at this discovery, because many islands supported dwarf versions of mainland animals during the Ice Ages.

Our climate, atmospheric oxygen level, ocean composition, and similar vital conditions are kept livable by life's waste products, such as the oxygen emissions of plants. That something like Gaia is required is seen in the extreme disequilibrium of the earth's atmosphere compared to the near-equilibrium of the atmospheres of apparently lifeless Venus and Mars. For example, our atmosphere's 21% oxygen, a highly reactive gas, is many orders of magnitude higher than one would expect on a lifeless planet. Furthermore, life-friendly conditions have been maintained for billions of years despite large changes in the sun's output and the traumas of asteroid impacts. T.M . Lenton, writing in Nature, asks a salient question: How has planetary self-regulation (Gaia) been established and maintained by evolution and natural selection which operate on the level of individuals? In other words, evolution tells us that organisms should evolve so as to leave the most progeny not so as to regulate the atmosphere. Lenton answers that there must be feedback loops from the planetary environment that steer the evolution of individuals in the "proper" direction. Lenton goes on to explore some of these many feedback mechanisms; one obscure loop involves the production of dimethyl sulfide by marine phytoplankton. Truly, it ...

This was the time of the well-publicized, but still hypothetical, asteroid impact. It is said to have wreaked havoc on our wounded planet and, especially, the dinosaurs. Volcanos spewed out vast lava fields and filled the air with greenhouse gases and dust. It was a bad time for many life forms. Actually, It may have been far worse than generally advertised. In addition to the volcanic activity and climate change, the shock of the asteroid impact could have been sufficient to destabilize the immense amounts of methane hydrate that have long been locked up, frozen and dormant, in oceanic sediments all over the world. According to this scenario, once the shock of the asteroid impact released the methane from its icy prison, it rose to the surface of the oceans in a world-wide burp. Methane, unfortunately for the dinosaurs and many other life forms, is highly flammable. Lightning could have ignited it almost immediately if it was concentrated enough. A colossal firestorm might have then enveloped the entire planet. The whole atmosphere could have been afire. This, according to B. Hurdle and colleagues at the Naval Research Laboratory, who speculate that the dinosaur hegemony may ended suddenly in flames rather than ...

The sudden change in the abundance of forest plants suggests that the winters became much more severe while the summers remained about the same. At about the same time, the radiolaria were devastated by some sort of disaster. This was also the time when the North American tektite strewn field was deposited -- a field that stretches halfway around the world. John O'Keefe hypothesizes that some of the tektites and microtektites that rained down during this period missed the earth and went into orbit around it, forming an opaque Saturn-like ring. This ring might have lasted a million years or more; and its shadow could have caused the extrasevere winters postulated from botanical data.

CO2 is a green-house gas, and its reduction should slow global warming. At least, this is how the Kyoto logic went. More trees may be good for the environment in the tropics, but the reverse is true in lands that are covered with snow most of the year. This is be-cause snow reflects much of the impinging solar energy back into space. If these northern lands were heavily forested, much of the solar energy would be absorbed and converted into heat.

He defines Gaia in an early paragraph: "In the early 1970s, Lynn Margulis and I introduced the Gaia hypothesis. It postulated the earth to be a self-regulating system comprising the biota and their environment, with the capacity to maintain the climate and the chemical composition at a steady state favorable for life." L. Margulis is an author of Micro-Cosmos and a champion of evolution-via-endosymbiosis; that is, diverse organisms uniting to create new species. Going back to Lovelock's review, there is little that is anomalous on a small scale. Of course, on a large-scale, the data supporting the concept of life-as-a -whole manipulating the atmosphere, oceans, etc., to perpetuate and perhaps improve itself are highly anomalous, because the Gaia hypothesis is far out of the scientific mainstream.

And, believe it or not, the rains of tektites discussed below may have been the forerunners of climatic catastrophes similar to the postulated nuclear winters. We shall call them "meteor-impact winters. First, a tad of background: Great meteor impacts and tektite events seem to have occurred nearly simultaneously with deep-cutting biological extinctions and reversals of the earth's magnetic field. Ever since this apparent synchrony was recognized a few decades ago, theorists have been vying in generating scientific scenarios, especially some mechanism that would reverse the earth's magnetic field. New entrants in the lists are R. Muller and D. Morris, two Berkeley physicists. Here is how they see it: "A sufficiently large asteroid or cometary nucleus hitting the Earth lofts enough dust to set off something like a 'nuclear winter.' The cold persists long after the dust settles because of the increased reflectivity of the snow-covered continents. In the course of a few centuries, enough equatorial ocean water is transported to the polar ice caps to drop the sea level about 10 meters and thus reduce the moment of inertia of the solid outer reaches of the Earth (crust and mantle) by a part in a million.

"A large number of anomalous landforms on Mars can be attributed to glaciation, including the action of ice and meltwater. Glacial landscapes are concentrated south of lat -33 and in the Northern Plains suggesting vast Austral and Boreal ice sheets. Crater densities on the glaciated terrains indicate that the final glacial epoch occurred late in Martian history. Thus, Mars may have had a relatively warm, moist climate and dense atmosphere much later than previously believed."

Old Kingdom craftsmen laboriously cut this hard, black, glassy rock into royal sarcophagi and pavements for the mortuary temples at Giza just outside Cairo. To transport the heavy blocks of basalt from the quarry to Giza, the Egyptians built a quay on Lake Moeris, which then had an elevation of 66 feet above sea level and was located 7 ½ miles southeast of the quarry. (The Lake is now much smaller and 148 feet below sea level, indicating a large climate change.) Then, when the Nile flooded and its waters reached a gap in the hills separating the Lake and the Nile, the Egyptians were able to float the blocks of basalt over to the Nile and down to Cairo. Good thinking! But how did they transport the heavy blocks 7 ½ miles from quarry to quay? The answer: What was apparently the first paved road on the planet. This 4,600-year-old engineering feat averaged 6 ½ feet wide and was paved with thousands of slabs of sandstone and limestone, with some logs of petrified wood thrown in. Since the slabs show no grooves, it is thought that the stone-laden sleds moved on rollers.

Spices contain chemical compounds that inhibit or kill the bacteria and fungi that are more likely to poison foods where ambient temperatures are higher. Eaters of spicier foods are more likely to survive in these areas. This is not just a surmise. A study of 4578 recipes from 93 cookbooks from all over the world have been analyzed for spice content. Sure enough, the hotter the climate, the more recipes using spices and the hotter the spices used.

However, the appearance of Terra Australis Re on Orontius Finaeus' map of 1531 and the depiction of a nearly identical continent on Mercator's 1538 map reveal sufficient, accurate knowledge of Antarctic features for us to conclude that someone discovered and mapped Antarctica well before 1500. The question is: Who? An interesting feature of Fineaeus' map is the reduced ice cover compared with what we find today. The Ross Ice Shelf, for example, was almost nonexistent. Such changes in ice cover are consistent with the modern theory of Antarctic climate changes. Apparently, the seas surrounding Antarctica were a bit warmer before 1500, and some unidentified early mariners brought knowledge of this continent back to Europe.

Kerr reviews several recent studies of fossil bryozoans and snails. Some of these painstaking dissections of the fossil record were carried out by scientists initially committed to Darwinian gradualism. Even these researchers have been forced to acknowledge that much biological evolution proceeds not in minute steps but by large jumps or saltations. Such abrupt speciation is tough enough to explain, but even more daunting are those species untouched by change over millions, even hundreds of millions of years. Indeed, the major characteristic of the fossil record and, therefore, earth life as a whole, has been stasis rather than speciation, despite all manner of asteroid impacts and climatic traumas. Nevertheless, many biologists think that species are somehow frozen in time by environmental forces that keep them from straying from their little niches. This being so, paleontologist D.

Some falls as tektites; the rest forms a temporary ring around the earth. The ring shadows parts of the earth, causing radical climate changes and, as a consequence, biological extinctions.

My assembly of published work indicates a remote connection between quiet periods and anoxic events and suggests its form: Magnetic quiet periods coincide with fast seafloor spreading. During these periods, buoyant spreading ridges displace seawater into broad shelves, thus decreasing earth's albedo and causing global warming. Temperature gradients, and thus density gradients, from pole to equator decrease in surface waters, and the deep ocean currents of oxygenated polar waters wane. Oxygen minimum zones intensify and widen; anoxic conditions throughout entire basins are indicated by black shales deposited in the deep sea.

The effects on the earth's climate could be large. If even greater fluxes of icy meteors were intercepted in the past, one might account for "pluvial episodes" on the planets. And further, comets now seem to transport "primordial organic sludge" around the solar system, as mentioned earlier under ASTRONOMY. We will leave further speculation to the reader.

... sea levels. The records from the Seven Stone Light Vessel are corroborated by an analysis of more then 20,000 wave charts of the North Atlantic drawn between 1960 and 1988. It therefore seems clear that something unusual is going on in the North Atlantic. One would suspect increased winds, but velocities measured at Seven Stone have remained constant while wave heights rose. It is concluded that the bigger waves are not generated by local winds; rather, they are swells that have been created thousands of miles away. The cause of these larger swells now affecting the entire North Atlantic is not known. The authors of this paper are forced to conclude with: "It should be noted that so far it has not been possible to attribute the observed change to either an anthropogenic cause or to natural climate variability on decadal time scales."

The Eltanin asteroid hits. About 2.2 million years ago, a chunk of space debris about a kilometer in diameter splashed down in the Bellingshausen Sea between Antarctica and South America. It was some splash! The splash zone was about 20 kilometers across, waves 4 kilometers high raced away from Ground Zero, and a column of salt water ascended miles high into the upper atmosphere. The TNT equivalent is estimated at 12 billion tons. Ice clouds formed and shaded the planet, causing severe climate changes. On the floor of the Bellingshausen Sea, 5 kilometers deep, lies the Eltanin Impact Structure. Today, we can still see the geological consequences thousands of kilometers from the impact point. The puzzling remains of marine diatoms in Antarctica's dry valleys may well be fallout from the cubic kilometers of seawater blasted out of the Bellingshausen Sea. More formidable were the giant tsunamis that fanned out at jet speeds toward South America and Australia. On the deep ocean these tsunamis were only 20-40 meters high, but as they approached land, they slowed and piled up into walls of water that approached a kilometer in height. Even after 2.2 . million years, geologists think they can see traces of these tsunamis in Australia and New Zealand. The mysterious bone beds near ...

The thylacine (or Tasmanian wolf or tiger) has been reported repeatedly in recently years. The last captive specimen of the marsupial tiger or thylacine died in a Tasmanian zoo in 1936. No living specimen has been verified since, but sporadic reports persist in Tasmania, Victoria, and Western Australia. H. Nix, of the Australian National University's Centre for Resource and Environmental Studies, has a computer program based upon detailed descriptions of climatic, topographic, and environmental factors that identifies areas where a particular animal or plant could flourish. Nix gathered the environmen tal requirements of the thylacine from records of where they had been shot and trapped in the past. This plus the computer program allowed Nix to identify prime thylacine territory. Compar-ing this information with the best sightings over the past 60 years, Nix found perfect agreement. In other words, post-extinction reports of thylacines come from just those areas where one would expect them to! (Anonymous; "Computers Help to Hunt the Tasmanian Tiger," New Scientist, p. 24, March 10, 1990.) Comment. This all sounds a bit tauto logical; that is, like "circular reasoning"! Reference. The possible late survival of the thylacine is covered in BMD12 in our ...

... the edge of a vast inland sea. In ancient China, conditions were much harsher. A modern-day equivalent would be the Great Salt Lake Basin of Utah. Water did exist in vast shallow lakes, but it was often alkaline and high in soda. The vegetation was scrubland with coniferous forests on the higher ground." (Anderson, Ian; "Chinese Unearth a Dinosaurs' Graveyard," New Scientist, p. 26, November 12, 1987.) Comment. To these Gobi observations should be added those above from northern Alaska, all of 70 north latitude, which suggest that dinosaurs also survived in a land where darkness reigned almost six months of the year. It seems that these great beasts could live almost anywhere. Why, then, do most scientists maintain that climatic changes wiped them out?

... s mass distribution, some sort of subterranean indigestion, like a subducted ocean plate suddenly plunging through into the lower mantle. (Kerr, Richard A.; "Did the Dinosaurs Live on a Topsy-Turvy Earth?" Science, 287:406, 2000.) The biological consequences of such a sudden tilting could have been severe. The event -- known as rapid true polar wander -- may have been accompanied by worldwide volcanic upheavals and reorganization of tectonic plates that would have played havoc with anything living in the Late Cretaceous period, 65 million to 99 million years ago. Although the notion that an asteroid was the immediate cause of dinosaur extinction about 65 million years ago has won wide acceptance, many paleontologists have argued that volcanic activity may have played a role in changing the climate and sending populations of the giant creatures into decline.

... doubly lucky! Computer runs demonstrate that the presence of our large moon has stabilized the earth's spin axis down the eons. Presently, the earth's spin axis makes an angle of 23.5 with the plane of the earth's orbit (its "obliquity"). The well-known result is our yearly procession of seasons. Without the steadying effect of the moon, however, the earth's obliquity would probably have swung chaotically over much larger values. Such extreme changes would have been inimical to the development of life, particularly advanced life. As a case in point, the polar axis of Mars, with only two tiny moons to dampen its spin excursions, seems to have gone through many wild swings, as indicated in the figure. What deadly climatic changes must have wracked our sister planet! (Touma, Jihad, and Wisdom, Jack; "The Chaotic Obliquity of Mars," Science, 259: 1294, 1993. Also: Laskar, J., and Robutel, P.; "The Chaotic Obliquity of the Planets," Nature, 361:608, 1993.) Comment. The successful evolution of higher life on earth (a presumption!) therefore seems to have depended upon the gravitational shields of Jupiter and Saturn as well as the presence of our unusually large satellite. How likely is this combination of planets and satellites in the rest of the universe? Of course, life-as-we-know-it also requires just the right kind of central star and a planet with good air and water ...

... , the aerosols spread around the globe and can remain suspended in the stratosphere for years. Because solar radiation is easily absorbed and backscattered by the volcanic particles, a haziness in the sky and a dimming of the Sun and Moon are produced. Very dense and widespread dry fogs occur, on the average, once every few centuries. The sizes and intensities of some of the largest of them before the modern scientific era have been estimated by several indirect methods. The densest and most persistent dry fog on record was observed in Europe and the Middle East during AD 536 and 537. Despite the earliness of the date, there is sufficient detailed information to estimate the optical depth and mass of this remarkable stratospheric dust cloud. The importance of this cloud resides in the fact that its mass and its climatic consequences appear to exceed those of any other volcanic cloud observed during the past three millenia. Although the volcano responsible remains a mystery, a tropical location (perhaps the volcano Rabaul on the island of New Britain, Papua, New Guinea) can be tentatively inferred." (Stothers, R.B .; "Mystery Cloud of AD 536," Nature, 307:344, 1984.) Comment. Some of the "dry fogs" were accompanied by luminous nights, as in 1821 and 1831.
