Los Angeles.
His researches have embraced a remarkable diversity of
natural phenomena and his professional interests are further
extended by his participation in national science policy-making.

Among future means of obtaining national objectives by force, one
possibility hinges on man's ability to control and manipulate the
environment of his planet. When achieved, this power over his
environment will provide man with a new force capable of doing great
and indiscriminate damage.
Our present primitive understanding of deliberate environmental
change makes it difficult to imagine a world in which geophysical
warfare is practiced. Such a world might be one in which nuclear
weapons were effectively banned and the weapons of mass destruction
were those of environmental catastrophe.
Alternatively, I can envisage a world of nuclear stability resulting
from parity in such weapons, rendered unstable by the development by
one nation of an advanced technology capable of modifying the
Earth's environment. Or geophysical weapons may be part of each
nation's armory. As I will argue, these weapons are peculiarly
suited for covert or secret wars.
Science fiction literature contains many suggestions of how wars
would progress if man indeed possessed the ability to change
weather, climate, or ocean currents. Many of these fictional
suggestions, and other more serious discussions, fail to take into
account the limitations of nature.
Jules Verne gave a detailed discussion of displacing the Earth's
polar caps, thus making the world's climatic zones more equitable
(Les Voyages Extraordinaires, 1889).
Verne's proposal was to eliminate the 23º tilt in the Earth's axis,
putting it at right angles to the Sun-Earth plane.
However, as Verne
correctly pointed out in a subsequent discussion, the Earth's
equatorial bulge stabilizes our planet and even the launching of a
180,000-ton projectile would produce a displacement of only 1/10
micron.
Senator Estes Kefauver, Vice-Presidential candidate in the 1956
American election, rediscovered Verne's original proposal and was
seriously concerned with the tipping of the Earth's axis. He
reported that the Earth's axis could, as the result of an H-bomb
explosion, be displaced by 10º.
Either Senator Kefauver or his
scientific advisers neglected the stabilizing influence of the Earth's
bulge.
The maximum displacement that can be expected from the explosion of
a 100-megaton H-weapon is less than one micron, as Walter Munk and I
pointed out in our book,
Rotation of the Earth (Cambridge, 1960).
Substantial progress within the environmental sciences is slowly
overcoming the gap between fact and fiction regarding manipulations
of the Earth's physical environment. As these manipulations become
possible, history shows that attempts may be made to use them in
support of national ambitions.
To consider the consequences of environmental modification in
struggles among nations, we need to consider the present state of
the subject and how postulated developments in the field could lead,
ten to fifty years from now, to weapons systems that would use nature
in new and perhaps unexpected ways.
The key to geophysical warfare is the identification of the
environmental instabilities to which the addition of a small amount
of energy would release vastly greater amounts of energy.
Environmental instability is a situation in which nature has stored
energy in some part of the Earth or its surroundings far in excess
of that which is usual.
To trigger this instability, the required
energy might be introduced violently by explosions or gently by
small bits of material able to induce rapid changes by acting as
catalysts or nucleating agents.
The mechanism for energy storage
might be the accumulation of strain over hundreds of millions of
years in the solid Earth, or the super-cooling of water vapor in
the atmosphere by updraughts taking place over a few tens of
minutes.
Effects of releasing this energy could be world-wide, as in the case
of altering climate, or regional, as in the case of locally excited
earth quakes or enhanced precipitation.
WEATHER
MODIFICATION
The Earth's atmosphere is an envelope of air which rotates, for the
most part, at the same speed as the underlying continents and
oceans.
The relative motion between the atmosphere and the Earth
arises from sources and sinks of energy which vary in location and
strength but which have, as their ultimate source, the Sun's
radiation.
The quantities of energy involved in weather systems exceed by a
substantial margin the quantity of energy under man's direct
control.
For instance,
-
the typical amount of energy expended in a
single tornado funnel is equivalent to about fifty kilotons of
explosives
-
a single thunderstorm tower exchanges about ten times
this much energy during its lifetime
-
an Atlantic hurricane of
moderate size may draw from the sea more than 1,000 megatons of
energy.
These vast quantities of energy make it unlikely that
brute-force techniques will lead to sensible weather modification.
Results could be achieved, however, by working on the instabilities
in the atmosphere.
We are now beginning to understand several kinds
of instabilities in the atmosphere. Super cooled water droplets in
cold clouds are unstable, but they remain liquid for substantial
periods of time unless supplied with nuclei on which they can
freeze.
Conversion of water droplets to ice through the introduction of artificial
nuclei can provide a local source of energy. This released heat can
cause rising air currents which in turn lead to further formation of
super cooled water. This process may lead to rainfall at the ground
greater than that which would have been produced without the artificial
nucleation.
A second instability may arise, in which water vapor condenses into
water, again affecting the distribution of sensible energy. On a
larger scale, there is the so-called baroclinicin stability of
atmospheric waves that girdle the planet.
Through the imbalance of
heat between equator and pole, energy in this instability is stored,
to be released in the creation of large cyclonic storms in the
temperate zones. There are other, less well understood instabilities
capable of affecting climate; I shall return to them later.
What is the present situation with respect to weather modification
and what might be reasonably expected in the future?
Experiments
over the past eighteen years have demonstrated unequivocally that
clouds composed of super cooled water droplets can be transformed
into ice-crystal clouds by seeding them with silver iodide, ‘dry
ice' (frozen carbon dioxide) and other suitable chemical agents.
This discovery has been applied operationally in the clearance of
airports covered by super cooled ground fog. No analogous technique
has yet evolved for clearing warm fog, although several promising
leads are now being investigated. In the case of warm fog, the
atmospheric instability is that water vapor distributed in small
drops contains more surface energy than the same water distributed
in large drops.
The trick for clearance of this warm fog will be to
discover some way of getting the small drops to organize themselves
into larger ones and then fall to the ground.
There is increasing, though inconclusive, evidence that rainfall
from some types of clouds and storm systems in temperate regions can
be increased by ten to fifteen per cent by seeding.
Somewhat more
controversial evidence indicates that precipitation can be increased
from tropical cumulus by techniques similar to those employed in
temperate regions. Preliminary experiments on hurricanes have the
aim of dissipating the clouds surrounding the eye of the storm in
order to spread the energy of the hurricane and reduce its force.
The results are controversial but indicate that seeding can, in
certain circumstances, lead to a marked growth in the seeded cloud.
This possibility may have merit in hurricane modification, but
experimentation has not yet resulted in a definitive statement.
Regarding the suppression of lightning, there is mixed but largely
promising evidence that the frequency of cloud-to-ground strokes can
be reduced by the introduction of ‘chaff', strips of metallic foil
of the kind used for creating spurious echoes in enemy radars.
In looking to the future, it is quite clear that substantial
advances will be made in all of these areas of weather modification.
Today, both military and civilian air transport benefit from progress
in the clearance of ground fog. Further progress in the technology
of introducing the seeding agent into the fog makes it likely that
this type of fog dispersal will become routine. In a sense, fog
clearing is the first military application of deliberate manipulation
of weather, but it is, of course, very limited.
Large field programs are being undertaken in the United States to
explore further the possibility of enhancing precipitation,
particularly in the western and north-eastern states.
On the high ground of the western states, snow from winter storms
provides much of the country's moisture.
Investigations are under
way to see if seeding can lead to an increased snowpack and thus
enhance the water resources. Intense interest in this form of
weather modification, coupled with an increased investigation of the
physics of clouds, is likely to lead to effective cloud modification
within the next five to fifteen years.
At present, the effects are
measured only statistically and too little has been done in cloud
observation before and after seeding in the way of precisely
pinpointing which clouds are most likely to be affected.
As far as military applications are concerned, I conjecture that
precipitation enhancement would have a limited value in classical
tactical situations, and then only in the future when controls are
more thoroughly understood.
One could, for example, imagine field
commanders calling for local enhancement of precipitation to cover
or impede various ground operations.
An alternative use of cloud seeding might be applied strategically.
We are presently uncertain about the effect of seeding on
precipitation downwind from the seeded clouds. Preliminary analysis
suggests that there is no effect 200-300 miles downwind, but that
continued seeding over a long stretch of dry land clearly could
remove sufficient moisture to prevent rain 1,000 miles downwind.
This
extended effect leads to the possibility of covertly removing
moisture from the atmosphere so that a nation dependent on water
vapor crossing a competitor country could be subjected to years of
drought.
The operation could be concealed by the statistical
irregularity of the atmosphere. A nation possessing superior
technology in environmental manipulation could damage an adversary
without revealing its intent.
Modification of storms, too, could have major strategic implications.
As I have mentioned, preliminary experiments have been carried out
on the seeding of hurricanes. The dynamics of hurricanes and the
mechanism by which energy is transferred from the ocean into the
atmosphere supporting the hurricane are poorly understood. Yet
various schemes for both dissipation and steering can be imagined.
Although hurricanes originate in tropical regions, they can travel
into temperate latitudes, as the residents of New England know only
too well.
A controlled hurricane could be used as a weapon to terrorize
opponents over substantial parts of the populated world. It is
generally supposed that a hurricane draws most of its energy from
the sea over which it passes.
The necessary process of heat transfer
depends on wave action which permits the air to come in contact with
a volume of water.
This interaction between the air and water also
stirs the upper layers of the atmosphere and permits the hurricane
to draw on a substantially larger reservoir of heat than just the
warm surface water.
There may be ways, using monomolecular films of
materials like those developed for covering reservoirs to reduce
evaporation, for decreasing the local interaction between sea and
air and thus preventing the ocean from providing energy to the
hurricane in an accelerated fashion. Such a procedure, coupled with
selective seeding, might provide hurricane guidance mechanisms.
At present we are a long way from having the basic data and
understanding necessary to carry out such experiments; nevertheless,
the long-term possibility of developing and applying such techniques
under the cover of nature's irregularities presents a disquieting
prospect.
CLIMATE
MODIFICATION
These manipulations become possible, history shows that attempts may
be made to use them
in support of national ambitions.
To consider
the consequences of environmental modification in struggles among
nations, we need to consider the present state of the subject and
how postulated developments in the field could lead, ten to fifty
years from now, to weapons systems that would use nature in new and
perhaps unexpected ways.
The key to geophysical warfare is the identification of the
environmental instabilities to which the addition of a small amount
of energy would release vastly greater amounts of energy.
Environmental instability is a situation in which nature has stored
energy in some part of the Earth or its surroundings far in excess
of that which is usual. To trigger this instability, the required
energy might be introduced violently by explosions or gently by
small bits of material able to induce rapid changes by acting as
catalysts or nucleating agents.
The mechanism for energy storage
might be the accumulation of strain over hundreds of millions of
years in the solid Earth, or the super-cooling of water vapor in
the atmosphere by updraughts taking place over a few tens of
minutes.
Effects of releasing this energy could be world-wide, as in the case
of altering climate, or regional, as in the case of
locally excited
earthquakes or enhanced precipitation.
In considering whether or not climate modification is possible, it is
useful to examine climate variations under natural conditions.
Firm geological evidence exists of a long sequence of
Ice Ages, in
the relatively recent past, which shows that the world's climate has
been in a state of slow evolution. There is also good geological,
archaeological and historical evidence for a pattern of smaller,
more rapid fluctuations superimposed on the slow evolutionary change.
For example, in Europe the climate of the early period following the
last Ice Age was continental, with hot summers and cold winters.
In
the sixth millennium B.C., there was a change to a warm humid
climate with a mean temperature of 5ºF higher than at present and a
heavy rainfall that caused considerable growth of peat.
This period,
known as a climatic optimum, was accentuated in Scandinavia by a
land subsidence which permitted a greater influx of warm Atlantic
water into the large Baltic Sea. The climatic optimum was peculiar.
While on the whole there was a very gradual decrease of rainfall,
the decrease was interrupted by long droughts during which the
surface peat dried. This fluctuation occurred several times, the main
dry periods being from 2000 to 1900, 1200 to 1000 and 700 to 500 B.C.
The last, a dry heat wave lasting approximately 200 years, was the
best developed. The drought, though not sufficiently intense to
interrupt the steady development of forests, did cause extensive
migrations of peoples from drier to wetter regions.
A change to colder and wetter conditions occurred in Europe about
500 B.C. and was by far the greatest and most abrupt alteration in
climate since the end of the last Ice Age.
It had a catastrophic
effect on the early civilization of Europe: large areas of forest
were killed by the rapid growth of peat and the levels of the Alpine
lakes rose suddenly, flooding many of the lake settlements.
This
climatic change did not last long; by the beginning of the Christian
era, conditions did not differ greatly from current ones. Since then
climatic variations have continued to occur and although none has
been as dramatics that of 500 B.C. a perturbation known as the
little ice age of the seventeenth century is a recent noteworthy
example.
The cause of these historical changes in climate remains shrouded in
mystery. The rapid changes of climate in the past suggest to many
that there exist instabilities affecting the balance of solar
radiation. Indeed, climate is primarily determined by the balance
between the incoming short-waveform the Sun (principally light) and
the loss of outgoing long-wave radiation (principally heat).
Three factors dominate the balance:
-
the energy of the Sun
-
the
surface character of terrestrial regions (water, ice, vegetation,
desert, etc.)
-
the transparency of the Earth's atmosphere to
different forms of radiated energy
In the last connection, the
effect of clouds in making cool days and relatively warm nights is a
matter of familiar experience.
But clouds are a manifestation rather
than an original determinant of weather and climate; of more
fundamental significance is the effect of gases in the atmosphere,
which absorb much of the radiation in transit from the Sun to the
Earth or from the Earth into space.
Intense X-rays and ultra-violet from the Sun, together with
high-energy atomic particles, are arrested in the upper atmosphere.
Only the narrow band of visible light and some short radio waves
traverse the atmosphere without serious interruption.
There has been much controversy in recent years about conjectured
overall effects on the world's climate of emissions of carbon
dioxide to the atmosphere from furnaces and engines burning fossil
fuels, and some about possible influences of the exhaust from large
rockets on the transparency of the upper atmosphere.
Carbon dioxide
placed in the atmosphere since the start of the industrial
revolution has produced an increase in the average temperature of
the lower atmosphere of a few tenths of a degree Fahrenheit.
The water vapor that may be introduced into the stratosphere by the
supersonic transport may also result in a similar temperature rise.
In principle it would be feasible to introduce material into the
upper atmosphere that would absorb either incoming light (thereby
cooling the surface) or outgoing heat (thereby warming the surface).
In practice, in the rarefied and windswept upper atmosphere, the
material would disperse rather quickly, so that military use of such
a technique would probably rely upon global rather than local
effects. Moreover, molecular material will tend to decompose, and
even elemental materials will eventually be lost by diffusion into
space or precipitation to the surface.
At intermediate levels, in the stratosphere, materials may tend to
accumulate though the mixing time for this part of the atmosphere is
certainly less than ten years and may be a few months.
If a nation's meteorologists calculated that a general warming or
cooling of the Earth was in their national interest, improving their
climate while worsening others, the temptation to release materials
from high-altitude rockets might exist.
At present we know too little about the paradoxical effects of
warming and cooling, however, to tell what the outcome might be.
More sudden, perhaps much briefer but nevertheless disastrous
effects, are predictable if chemical or physical means were
developed for attacking one of the natural constituents of the
atmosphere ozone.
A low concentration of ozone (O3, a rare molecular form of oxygen)
in a layer between fifteen and fifty kilometers altitude has the
utmost significance for life on land. It is responsible for absorbing
the greater part of the ultra-violet from the Sun. In mild doses,
this radiation causes sunburn; if the full force of it were
experienced at the surface, it would be fatal to all life - including farm crops and herds
- that could not take shelter.
The ozone is replenished daily, but a temporary ‘hole' in the ozone
layer over a target area might be created by physical or chemical
action.
For example, ultra-violet at 250 millimicrons wavelength
decomposes ozone molecules, and ozone reacts readily with a wide
range of materials. At present, we can only tentatively speculate
about modifying the short-wave radiation at its source. We
have discovered major instabilities on the Sun's surface which might
be manipulated many years hence.
In a solar flare, for example, 10 megatons of energy are stored in
distorted magnetic fields. With advanced techniques of launching
rockets and setting off large explosions, we may sometime in the
future learn to trigger these instabilities.
For the near future, however, modification will not be in the
short-wave in- coming radiation but in the long-wave outgoing
radiation.
The usual schemes for modifying climate involve the
manipulation of large ice fields. The persistence of these large ice
fields is due to the cooling effects of the ice itself, both in reflecting
(rather than absorbing) incoming short-wave radiation and in
radiating heat at higher rate than the usual ground cover.
A commonly suggested means of climate modification involves thin
layers of colored material spread on an icy surface, thus
inhibiting both the reaction and radiation processes, melting the
ice, and thereby altering the climate. Such a procedure presents
obvious technical and logistic difficulties.
For example, if one wished to create a surface coating of as little
as one micron thickness to cover a square 1,000 kilometers in size,
the total material for this extremely thin coating would weigh a
million tons or more, depending upon its density. So the proposals
to dust from the air some of the globe's extended ice sheets, are
unrealistic and reflect a brute-force technique, taking no advantage
of instabilities within the environment.
While it may be technologically difficult to change an ice cap's
surface character, and thus its thermal properties, it may be
possible to move the ice, taking into account the gravitational
instability of ice caps.
The gravitational potential energy of water as a thick, high ice cap
is much greater than it would be at sea level. This fact makes it
possible, at least in principle, to devise schemes for bringing
about redistribution in the ice. Indeed, A. T. Wilson has proposed a
cyclical theory for the Ice Ages based on this instability.
The main points of Wilson's theory are as follows: Antarctica is
covered by an ice sheet several kilometers thick.
Pressure at the
bottom of the ice is great enough to keep the ice at or near its
melting point; water is an unusual material in that a pressure
increase lowers rather than raises its melting point. An increase in
thickness of the ice sheet could result in melting at the bottom.
The resulting ice-water mixture along the sole of the glacier would
permit flow by a process of freezing and melting - a flow process much
more effective than ordinary plastic fiow.
If such an instability occurs, the ice
sheet will flow out on to the surrounding sea and a large ice shelf
will be formed between Antarctica and the ocean around it. As a
consequence, short-wave solar radiation will be reflected and there
will be enhanced loss of heat by radiation at the long wave-lengths,
causing cooling and the inducement of world-wide glaciation.
Once the ice shelf is in the ocean, it will begin to melt and
eventually will be removed.
The ice remaining on land will be much
thinner than before. As the reflectivity of the southern hemisphere
decreases with the melting of the Antarctic ice cap, the global
climate will grow warmer again, corresponding to the start of an
interglacial period. The ice cap
will slowly form again.
Commenting on Wilson's theory, J.T. Hollin has noted the
possibility of a catastrophic surge or advance of the ice sheet,
such as has been recorded from small glaciers on numerous occasions.
The largest surge yet reported is probably that of the ice cap in
Spitsbergen which advanced up to twenty-one kilometers on a front of
thirty kilometers sometime between 1935 and 1938. There are also
reports of glacial advances at speeds up to 100 meters per day.
Hollin speculates that, once the bottom-melting phase of a
gravitationally unstable ice cap is reached, it will move quickly.
In addition to trapped geothermal heat melting the ice at the
bottom, there are additional contributions from frictional heat
generated as the glacier scrapes along the solid ground. If the
speculative theory of Wilson is correct (and there are many
attractive features to it) then a mechanism does exist for
catastrophically altering the Earth's climate.
The release of
thermal energy, perhaps through nuclear explosions along the base of
an ice sheet, could initiate outward sliding of the ice sheet which
would then be sustained by gravitational energy. One megaton of
energy is sufficient to melt about 100 million tons of ice.
One
hundred megatons of energy would convert 0.1 cm of ice into a thin
layer of water covering the entire Antarctic ice cap. Lesser amounts
of energy suitably placed could undoubtedly initiate the outward flow
of the ice.
What would be the consequences of such an operation?
The immediate
effect of this vast quantity of ice surging into the water, if
velocities of 100 meters per day are appropriate, would be to create
massive tsunamis (tidal waves) which would completely wreck coastal
regions even in the northern hemisphere.
There would then follow
marked changes in climate brought about by the suddenly changed reflectivity
of the Earth. At a rate of 100metres per day, the centre of the ice
sheet would reach the land's edge in forty years.
Who would stand to benefit from such application?
The logical
candidate would be a landlocked equatorial country. An extended
glacial period would ensure near-Arctic conditions over much of the
temperate zone, but temperate climate with abundant rainfall would
be the rule in the present tropical regions.
FUTURE OF
WEATHER AND CLIMATE MODIFICATION
The foregoing perhaps represents a more positive view of weather and
climate modification than that held by many Earth scientists.
I
believe this view is justified as it is based on three scientific and
technological advances.
-
First, understanding of basic meteorology has advanced to such an
extent that mathematical models of the atmosphere here have been
developed incorporating the most important elements. Physical
processes in clouds, in turbulent exchanges at the surface, and in
transmission of radiation through the atmosphere are no longer as
mysterious as they once were. The volumes simulated by the models
range from the size of a single cloud to the entire atmosphere;
these models are no longer primitive representations.
-
Secondly, the
advent of high-speed computers enables atmospheric models to be
studied in greater detail. These computers have a peculiar
importance to weather modification, since they will enable scientists
to carry out extended experiments to test whether or not various
schemes for manipulating the atmosphere are indeed possible and what
the outcome should be.
-
The third advance lending support to expectations for weather and
climate modification is the new array of instruments developed to
observe and detect changes in the atmosphere.
The most dramatic and
perhaps the most powerful is the meteorological satellite which
provides a platform whence the atmosphere can be observed, not only
in geographically inaccessible regions, but also with entirely new
physical measurements.
For example, meteorological satellites of the
future will permit the determination of humidity, temperature and
pressure as averaged over substantial volumes of the atmosphere,
providing quantities which are needed to develop the mathematical
models.
Sophisticated surface instrumentation, for observing
detailed processes within smaller parts of the atmosphere, provides
us with far more powerful tools with which to look at clouds and at
the interaction of the atmosphere with its boundaries than those
which were available ten or twenty years ago.
EARTHQUAKE
MODIFICATION
What causes earthquakes?
Over geological time, the irregular
distribution of heat-producing radioactive elements in the rock
layers gives rise to sub-surface temperature differences between
various parts of the Earth.
In the continents, granites and similar
rocks have concentrated radioactive elements near the surface; no
similar concentration has taken place in the sub-oceanic regions,
which may as a result be more than 100ºC cooler than the
corresponding sub-continental regions.
Such variations in
temperature along a horizontal line, due to the differences in the
vertical distribution of heat-producing elements, give rise to large
thermal stresses, causing strain analogous to that which cracks a
glass tumbler filled with hot water.
The strain tends to be greatest
in regions of abrupt temperature change along a horizontal line
through the Earth's crust. The strain may be partially relieved by
the slow convective flow of material in the deep Earth which is
thought by some geophysicists to push continents about.
But the strain can also be relieved by sharp fractures or by
movements along previous faults in rocks near the surface.
Movement
along a fault radiates energy outward, which results in an
earthquake. Each year approximately 200 megatons of strain energy is
released in this fashion, the largest earthquakes corresponding to
energy of the order of 100 megatons. The energy released depends on
the volume of material affected.
The largest earthquakes take place along faults having a linear
dimension of 1,000 kilometers, whereas smaller ones take place along
faults of one kilometer or less.
Major earthquakes tend to be
located along two main belts.
-
One belt, along which about eighty-five
per cent of the total energy is released, passes around the Pacific
and affects countries whose coastlines border this ocean, for
example Japan and the west coast of North America.
-
The second belt passes through the Mediterranean regions eastwards
through Asia and joins the first belt in Indonesia. Along these two
belts, large earthquakes occur with varying frequencies.
In California, a large earthquake might be expected once every 50 to
100 years, while Chile might expect such a disturbance once every
ten to twenty years.
Sometimes major earthquakes have occurred in
regions ordinarily thought of as being free from risk. For example,
the
New Madrid earthquake of 1811-12 devastated a large area of
central North America but had only slight cultural effects because
of the area's sparse population.
Today (1968), our detailed understanding of the mechanism that
causes an earthquake and of how the related instabilities can be
triggered is limited. Only within the last few years have serious
discussions of earthquake prediction begun, whereas moderately
reliable weather forecasts have been available for about the last
thirty to fifty years.
Currently, substantial effort is being made, primarily by Japan and
the United States, to develop techniques for forecasting
earthquakes.
These techniques are based to a large extent on the
determination of changing strain conditions of materials in the
rocks surrounding recognized fault zones. Of possible value is the
observation that, before an earthquake, the accumulating strain
accelerates.
Control of earthquakes is a prospect even more distant than that of
forecasting although two techniques have been suggested through
recent experience.
-
In the course of the underground testing of
nuclear weapons at the Nevada test site, it was observed that an
explosion apparently released local strain in the Earth. The
hypothesis is that the swift build-up of strain due to the
sudden release of energy in explosion discharges strain
energy over a large volume of material.
-
Another method of releasing strain energy has appeared from pumping
of underground water in the vicinity of Denver, Colorado, which has
led to a series of small earthquakes. The hypothesis here is that
underground water has provided local lubrication permitting adjacent
blocks to slip by one another. The use as a weapon system of the
strain energy instability within the solid Earth requires an
effective triggering mechanism.
A scheme for pumping water seems clumsy and easily detectable. (fracking?)
On the other hand, if the strain pattern in the crust can be
accurately determined, the phased or timed release of energy from
smaller faults, designed to trigger a large fault at some distance,
could be contemplated. This timed release could be activated through
small explosions and thus it might be possible to use this release
of energy stored in small faults at some distance from a major fault
to trigger that major fault.
For example, the
San Andreas Fault zone, passing near Los Angeles
and San Francisco, is part of the great earthquake belt surrounding
the Pacific. Good knowledge of the strain within this belt might
permit the setting off of the San Andreas zone by timed explosions
in the China Sea and Philippine Sea.
In contrast with certain
meteorological operations, it would seem rather unlikely that such
an attack could be carried out covertly under the guise of natural
earthquakes.
(Note: In 2012 these assumption are no longer valid
with numerous scalar technologies and ionospheric heater arrays)
MODIFICATION OF OCEANS
We are still in the very early stages of developing the theory and
techniques for predicting the state of the oceans.
In the past two
decades, methods have been devised for the prediction of surface
waves and surface wind distribution. A warning system for the
tsunamis (tidal waves) produced by earthquakes has also been
developed.
Certain currents within the oceans have been identified, but we do
not yet know what the variable components are; that is, what the
weather within the ocean is. Thus we have not been able to identify
any instabilities within the oceanic circulation that might be
easily manipulated. As in the case of the solid Earth, we can only
speculate tentatively about how oceanic processes might be
controlled.
One instability offering potential as a future weapon system is that
associated with tsunamis.
These frequently originate from the
slumping into the deep ocean of loosely consolidated sediments and
rocks perched on the continental shelf. Movement of these sediments
can trigger the release of vast quantities of gravitational energy,
part of which is converted in the motion of the tsunami.
For example if, along a 1,000-kilometre edge of a continental shelf,
a block 100 meters deep and 10 kilometers wide were dropped a
distance of 100 meters, about 100 megatons of energy would be
released. This release would be catastrophic to any coastal nation.
How could it be achieved? A series of phased explosions, perhaps
setting off natural earthquakes, would be a most effective way.
I
could even speculate on planning a guided tidal wave, where guidance
is achieved by correctly shaping the source which releases energy.
(Fukushima?)
BRAIN WAVES ROUND THE WORLD?
At heights of forty to fifty kilometers above the Earth's surface,
substantial numbers of charged particles are found which make this
part of the atmosphere, the ionosphere, a good conductor of
electricity.
The rocks and oceans are also more conducting than the lower
atmosphere. Thus, we live in an insulating atmosphere between two
spherical conducting shells or, as the radio engineer would put it,
in an
Earth-ionosphere cavity, or waveguide.
Radio waves striking either conducting shell tend to be reflected
back into the cavity, and this phenomenon is what makes conventional
long-distance radio communication possible. Only recently, however,
has there been any interest in natural electrical resonances within
the Earth-ionosphere waveguide.
Like any such cavity, the
Earth-ionosphere waveguide will tend to sustain radio oscillation at
certain frequencies in preference to others. These resonant
frequencies are primarily determined by the size of the Earth and
the speed of light, but the properties of the ionosphere modify them
to a certain extent.
The lowest resonances begin at about eight cycles per second, far
below the frequencies ordinarily used for radio communication.
Because of their long wavelength and small field strength, they are
difficult to detect. Moreover, they die down quickly, within 1/16
second or so; in engineering terms, the cavity has a short time
constant.
The natural resonant oscillations are excited by lightning strokes,
cloud-to-ground strokes being a much more efficient source than
horizontal cloud-to-cloud discharges. On the average, about 100
lightning strokes occur each second (primarily concentrated in the
equatorial regions) so that normally about six lightning flashes are
available to introduce energy before a particular oscillation dies
down.
A typical oscillation's field strength is of the order of 0.3 millivolts per
meter.
The power of the oscillations varies geographically.
For example,
for a source located on the equator in Brazil the maximum intensity
of the oscillation is near the source and at the opposite side of
the Earth (around Indonesia). The intensity is lower in intermediate
regions and towards the poles.
One can imagine several ways in which to increase the intensity of
such electrical oscillations. The number of lightning strokes per
second could be enhanced by artificially increasing their original
number. Substantial progress has been made in the understanding of
the physics of lightning and of how it might be controlled.
The natural oscillations are excited by randomly occurring strokes.
The excitation of timed strokes would enhance the efficiency with
which energy is injected into an oscillation.
Furthermore, the time
constant of the oscillation would be doubled by a four-fold increase
in the electrical conductivity of the ionosphere, so that any scheme
for enhancing that conductivity (for example, by injecting readily
ionized vapor) lowers the energy losses and lengthens the time
constant, which would permit a greater number of phased lightening
strokes before the decay of an oscillation.
The enhanced low-frequency electrical oscillations in the
Earth-ionosphere cavity relate to possible weapons systems through a
little understood aspect of brain physiology.
Electrical
activity in the brain is concentrated at certain
frequencies, some of it extremely slow, a little around five cycles
per second and very conspicuous activity (the so-called alpha
rhythm) around ten cycles per second. Some experiments have been
done in the use of a flickering light to pull the brain's alpha
rhythm into unnatural synchrony with it; the visual stimulation
leads to electrical stimulation.
There has also been work on direct electrical driving of the brain.
In experiments discussed by Norbert Wiener, a sheet of tin is
suspended from the ceiling and connected to a generator working at
ten cycles per second.
With large field strengths of one or two volts per centimeter
oscillating at the alpha-rhythm frequency, decidedly unpleasant
sensations are noted by human subjects.
The Brain Research Institute of the University of California is
investigating the effect of weak oscillating fields on human
behavior.
The field strengths in these experiments are of the order of a few
hundredths of a volt per centimeter. Subjects show small but
measurable degradation in performance when exposed to oscillating fields
for periods of up to fifteen minutes. The field strengths in these
experiments are still much stronger, by a factor of about 1,000,
than the observed natural oscillations in the Earth-ionosphere
cavity.
However, as previously noted, the intensity of the natural fluctuations
could be increased substantially and in principle could be
maintained for a long time, as tropical thunder storms are always
available for manipulation.
The proper geographical location of the source of lightning, coupled
with accurately-timed, artificially-excited strokes, could lead to a
pattern of oscillations that produced relatively high power levels
over certain regions of the Earth and substantially lower levels
over other regions. In this way, one could develop a system that
would seriously impair brain performance in very large populations
in selected regions over an extended period.
The scheme I have suggested is admittedly far-fetched, but I have
used it to indicate the rather subtle connections between variations
in man's environmental conditions and his behavior.
Perturbation of the environment can produce changes in behavior
patterns.
Since our understanding of both behavioral and environmental
manipulation is rudimentary, schemes of behavioral alteration on
the surface seem unrealistic.
No matter how deeply disturbing the
thought of using the environment to manipulate behavior for
national advantage is to some, the technology permitting such use
will very probably develop within the next few decades.
SECRET WAR AND CHANGING RELATIONSHIPS
Deficiencies both in the basic understanding of the physical
processes in the environment and in the technology of environmental
change make it highly unlikely that environmental modification will
be an attractive weapon system in any direct military confrontation
in the near future. (under deployment in 2012)
Man already possesses
highly effective tools for destruction.
Eventually, however, means other than open warfare may be used to
secure national advantage. As economic competition among many
advanced nations heightens, it may be to a country's advantage to
ensure a peaceful natural environment for itself and a disturbed
environment for its competitors.
Operations producing such conditions might be carried out covertly,
since nature's great irregularity permits storms, floods, droughts,
earthquakes and tidal waves to be viewed as unusual but not
unexpected.
Such a ‘secret war'
need never be declared or even known
by the affected populations. It could go on for years with only the
security forces involved being aware of it. The years of drought and
storm would be attributed to unkindly nature and only after a nation
were thoroughly drained would an armed take-over be attempted.
In addition to their covert nature, a feature common to several modification
schemes is their ability to affect the Earth as a whole.
The environment knows no political boundaries; it is independent of
the institutions based on geography and the effects of modification
can be projected from any one point to any other on the Earth.
Because environmental modification may be a dominant feature of
future world decades, there is concern that this incipient
technology is in total conflict with many of the traditional
geographical and political units and concepts.
Political, legal, economic and sociological consequences of
deliberate environmental modification, even for peaceful purposes,
will be of such complexity that perhaps all our present involvements
in nuclear affairs will seem simple.
Our understanding of basic environmental science and technology is
primitive, but still more primitive are our notions of the proper
political forms and procedures to deal with the consequences of modification.
All experience shows that less significant technological changes than
environmental control finally transform political and social
relationships. Experience also shows that these transformations are
not necessarily predictable, and that guesses we might make now,
based on precedent, are likely to be quite wrong.
It would seem,
however, that these non-scientific, non-technological problems are of
such magnitude that they deserve consideration by serious students
throughout the world if society is to live comfortably in a
controlled environment.
Author's note:
In the section on weather modification I have drawn
heavily on Weather and Climate Modification (National Academy of
Sciences, National Research Council, Washington, zg66). A. T.
Wilson's paper on ‘Origin of Ice Ages' appeared in Nature, vol. aox,
pp. z4y-g (xg64), and J. T. Hollin's comments in vol. ao8, pp. ra-16
(r 965).
Release of tectonic strain by underground nuclear explosion
was reported by F. Press and C. Archambeau in Journal of Geophysical
Research , vol. 67,pp. 337-43 (1962), and man-made earthquakes in
Denver by D. Evans in Geotimes , vol. to, pp. rr-rp.
