Abstract: The widespread, intentional and increasingly frequent chemical emplacement in
the troposphere has gone unidentified and unremarked in the scientific literature for years.
The author presents evidence that toxic coal combustion fly ash is the most likely
aerosolized particulate sprayed by tanker-jets for geoengineering, weather-modification
and climate-modification purposes and describes some of the multifold consequences on
public health. Two methods are employed: (1) Comparison of 8 elements analyzed in
rainwater, leached from aerosolized particulates, with corresponding elements leached into
water from coal fly ash in published laboratory experiments, and (2) Comparison of 14
elements analyzed in dust collected outdoors on a high-efficiency particulate air (HEPA)
filter with corresponding elements analyzed in un-leached coal fly ash material. The results
show: (1) the assemblage of elements in rainwater and in the corresponding experimental
leachate are essentially identical. At a 99% confidence interval, they have identical means
(T-test) and identical variances (F-test); and (2) the assemblage of elements in the HEPA
dust and in the corresponding average un-leached coal fly ash are likewise essentially
identical. The consequences on public health are profound, including exposure to a variety of
toxic heavy metals, radioactive elements, and neurologically-implicated chemically mobile
aluminum released by body moisture in situ after inhalation or through transdermal induction.

1. Introduction
   The interplay of political, military, and commercial interests during World War II led to the
   development and grand-scale deployment of a host of herbicides and pesticides such as
   dichlorodiphenyltrichloroethane (DDT). In her 1962 book Silent Spring [1] Rachel Carson called
   attention to the unintended consequences of herbicide and pesticide use, and launched the modern
   environmental movement. Half a century later there is growing evidence of a grave new and persistent
   global environmental health threat, again fomented by the interplay of political, military, and
   commercial interests. To date this new threat, posed by widespread, intentional tropospheric aerosolparticulate emplacement, has gone unremarked in the scientific literature for more than one decade.
   Here, based upon original research, the author discloses substantial evidence as to the identification
   and nature of the specific particulate substance involved and begins to describe the extent of this global
   public health and environmental threat.
   Recently there have been calls in both the popular and scientific press to begin discussions about the
   possibility of engaging in future stratospheric geoengineering experiments to counter global warming [2,3].
   Geoengineering, also called weather-modification, has been carried out for decades at much lower
   altitudes in the troposphere. The recent calls for open discussion of climate control or geoengineering
   tend to obscure the fact that the world's military and civilian sectors have modified atmospheric
   conditions for many decades as has been described by science historian, James R. Fleming [4].
   Some of the early weather-modification research resulted in programs like Project Skywater (1961–1988),
   the U.S. Bureau of Reclamation's effort to engineer “the rivers of the sky”; the U.S. Army's Operation
   Ranch Hand (1961–1971), in which the herbicide Agent Orange was an infamous part; and its Project
   Popeye (1967–1971), used to “make mud, not war” over the Ho Chi Minh Trail. These few examples
   of weather-modification, all of them secret at the time they were engaged, show that the weather is in
   the words of the military, “a force multiplier” [5].
   In the spring of 2014, the author began to notice tanker-jets quite often producing white trails across
   the cloudless blue sky over San Diego, California. The aerosol spraying that was happening with
   increasing frequency was a relatively new phenomenon there. The dry warm air above San Diego is
   not conducive to the formation of jet contrails, which are ice condensate. By November 2014 the
   tanker-jets were busy every day crisscrossing the sky spraying their aerial graffiti. In a matter of
   minutes, the aerosol trails exiting the tanker-jets would start to diffuse, eventually forming cirrus-like
   clouds that further diffuse to form a white haze that scattered sunlight, often occluding or dimming the
   sun. Aerosol spraying was occasionally so intense as to make the otherwise cloudless blue sky overcast,
   some areas of sky turning brownish (Figure 1). Sometimes the navigation lights of the tanker-jets were
   visible as they worked at night, their trails obscuring the stars overhead; by dawn the normally clear-blue
   morning sky already had a milky white haze. Regardless, aerosol spraying often continued throughout
   Int. J. Environ. Res. Public Health 2015, 12 9377
   the day. The necessity for daily aerosol emplacement stems from the relatively low spraying-altitudes
   in the troposphere where mixing with air readily occurs bringing down the aerosolized particulates and
   exposing humanity and Earth's biota to the fine-grained substance. The author's concern about the
   daily exposure to ultra-fine airborne particulate matter of undisclosed composition and its concomitant
   effect on the health of his family and public health in general prompted the research reported here.
   Figure 1. Composite of four images of the blue sky over San Diego taken on cloudless days
   showing various instances of the on-going daily tanker-jet spraying of ultrafine-particulates
   into the troposphere. Upper Left: Spraying just started. Note that one tanker-jet turned off
   the spray in mid-flight. The “clouds” are dispersed particulates; Lower Right: Overcast
   “clouds” produced by intense tanker-jet emplacement of particulates.
   Since the beginning of the 21st century there have been numerous observations of tanker-jet aerosol
   particulate spraying. Sometimes samples of rainwater, soil, and other residue were collected by
   concerned citizens and sent to commercial certified laboratories to be analyzed, although without an
   understanding of what tests should be made. The composition of the aerosolized particulate matter has
   been a tightly held secret. In the face of this unknown, there has been much sincere speculation in
   books and on the Internet, but also disinformation, attempts to convince the public that the particulate
   trails are nothing more than ice crystals formed from jet exhaust, and to pin on concerned citizens the
   pejorative moniker “conspiracy theorists”.
   From the variety of observations reported in books and on the Internet, one might reasonably
   conclude that, at least during the early years, various weather-modification experiments were
   undertaken. But as indicated by photographic data and chemical analyses of post-spraying rainwater,
   one particular methodology was developed that ultimately was observed by the author to be
   operational on a daily basis in the skies over San Diego, and reportedly is now operational over much
   of the United States and in a number of foreign countries as well [6]. Beside the observational
   commonality, post-spraying rainwater was frequently found to contain aluminum and barium,
   Int. J. Environ. Res. Public Health 2015, 12 9378
   two elements usually not present in naturally-occurring rainwater; sometimes strontium, a third
   element, was included in the tests and determined to be present [7]. The presence of strontium together
   with barium suggests that the undisclosed particulate matter is derived from a natural product, because
   alkaline earth elements, Group II on the Periodic Table, behave similarly and are often found together
   in nature. For example, cement contains calcium and often contains some strontium as well. That bit of
   insight evoked further considerations related to the potential costs and logistics of annually producing
   millions of tons of the undisclosed particulate matter and doing so out of public view.
   Industrial coal burning produces four types of coal combustion residuals (CCRs): fly ash, bottom ash,
   boiler slag, and flue gas desulfurization product (FGDP), i.e., gypsum. Bottom ash is heavy and settles
   out; coal fly ash, on the other hand, is comprised of micron and sub-micron particles that would go up the
   smokestack unless captured and stored. Because of its well-known adverse environmental health effects,
   Western nations now mandate that coal combustion fly ash is to be captured and stored [8,9].
   Representatives of coal burning utilities and their trade organizations actively promote commercial
   applications for coal fly ash, which, to name a few, include uses as additives to Portland cement,
   agricultural soil amendments, replacement for compacted backfills, mine reclamation, melting river
   ice, and as subsurface for roads. Some applications pose potential environmental health risks in the
   short term and/or in the long term as coal fly ash is a concentrated repository for many of the trace
   elements that were trapped in coal during its formation, including, but not limited to, arsenic, barium,
   beryllium, boron, cadmium, chromium, cobalt, lead, manganese, mercury, molybdenum, selenium,
   thallium, thorium, vanadium and uranium.
   Although seemingly unacknowledged in publicly accessible reports and in scientific literature as a
   potential material for geoengineering, coal fly ash is one major global waste product stream with the
   appropriate grain-size distribution for aerosolized tropospheric spraying that is readily available at
   extremely low cost and with existent processing and transport infrastructure. The author submits the
   following hypothesis: Coal fly ash is most likely the aerosolized particulate sprayed in the troposphere
   by tanker-jets for geoengineering, weather-modification and climate-modification purposes.
   The objectives of the research are to provide substantial scientific evidence as to the correctness of
   the hypothesis, namely, that coal fly ash is the aerosolized particulate sprayed in the troposphere by
   tanker-jets for geoengineering, weather-modification and climate-modification purposes and to reveal
   some of the adverse human public health consequences and the antagonistic consequences on Earth's
   environment and biota.
2. Experimental Section
   The methodology is two-fold: (1) Compare element ratios analyzed in rainwater, which were
   leached in the atmosphere from aerosolized particulates, with the corresponding element ratios that
   were extracted from coal fly ash into water in laboratory leaching experiments; and, (2) Compare the
   element ratios analyzed in dust collected outdoors on a HEPA filter with corresponding element ratios
   analyzed in coal fly ash material.
   One of the reasons coal fly ash is sequestered, usually in lined ponds, is that a variety of toxic
   chemical elements are readily extracted by water, including but not limited to aluminum, arsenic,
   cadmium, chromium, thallium, lead, mercury and uranium. Scientists have conducted leaching
   Int. J. Environ. Res. Public Health 2015, 12 9379
   experiments on coal fly ash samples, but none of the various investigations appear to be as thorough as
   that of Moreno et al. [10]. They obtained coal fly ash samples from 23 different European sources
   (from Spain, The Netherlands, Italy and Greece) which they analyzed for 33 chemical elements.
   They leached 100 grams of each coal fly ash sample with one liter of distilled water for twenty four
   hours, and then determined the concentrations of 38 elements in the leachate, the water-extract, from
   each experiment. Although there were some variations observed in the pre-leach coal fly ash chemical
   compositions and in the relative proportion of extracted elements in the leachate and variations in the
   resulting pH, the overall pattern of leachate elements was remarkably consistent among the different
   fly ash sources. Table 1 summarizes the average values for European coal fly ash pre-leach
   compositions and the average values of leachate chemical compositions that include those used in the
   present investigation.

With its normally limited natural cloud cover San Diego is ideal for observing tanker-jet dispersal
of ultra-fine particulates. Because the city lacks heavy industries and their particulate pollution, it is an
ideal environment to ascertain by rainwater measurement the nature of the specific particulates being
sprayed which are leached by rainwater. The author personally collected rainwater samples for
chemical analysis and compared those data to corresponding average values of experimental leachate
Int. J. Environ. Res. Public Health 2015, 12 9380
chemical analyses [10], which as shown below provides a firm basis for identifying the particulate
substance being emplaced as an aerosol in the troposphere as coal fly ash. Because of persistent
spraying, rainwater devoid of spray contamination was not available.
For three months during a period of intense aerial spraying in 2011, an individual in Los Angeles,
California captured and had analyzed outdoor air-borne particulates.The results were posted on the
Internet [11]; subsequently the author obtained the analytical laboratory report. The requested analyses
returned results for aluminum, barium and twelve trace elements. But the meaning of the data was not
clear at the time. Comparison of those data with corresponding pre-leach average coal fly ash chemical
analyses (Table 1), as shown below, further reinforces the correctness of identifying the particulate
substance as coal fly ash that is being sprayed into the troposphere by tanker-jets for geoengineering.

3. Results and Discussion
   The average elemental composition of each of the 38 elements from the 23 different sources of
   European coal fly ash leach studied by Moreno et al. [10], presented as ratios relative to aluminum,
   is shown in Figure 2 as a function of Atomic Number. Normalization to one common element, in this
   case aluminum, makes comparisons possible when total mass or total volume is not available. In this
   plot, the less abundant leachate element ratios are not shown. Note that aluminum (Atomic Number 13),
   strontium (38), and barium (56), elements which are sometimes determined in post-spraying rainwater,
   are relatively abundant.
   Figure 2. The average leachate chemical concentration of each of the 38 elements from the
   23 different sources of European coal fly ash (Table 1) studied by [10], normalized to
   aluminum so as to facilitate comparison with analyzed post-aerosol-spraying rainwater.
   Elements of lower concentration are not shown. Red leachate elements correspond to those
   measured in San Diego rainwater (Figure 3), from left to right, Boron, Magnesium,
   Aluminum, Sulfur, Calcium, Iron, Strontium and Barium.
   Int. J. Environ. Res. Public Health 2015, 12 9381
   Two commercial state-of-California certified laboratories, Babcock Laboratories, Inc. and Basic
   Laboratory, were engaged for the San Diego rainwater analyses by inductively coupled plasma mass
   spectrometry. Their analytical results were consistent to within 2%–10%. Figure 3 shows concentrations
   of 8 chemical elements, normalized to aluminum, measured in post-aerosol-spraying San Diego
   rainwater for comparison with corresponding element ratios in the [10] water-extract of coal fly ash
   leaching experiments (Table 1).
   Figure 3. The chemical concentrations of 8 elements, normalized to aluminum, measured
   in post-aerosol-spraying San Diego rainwater for comparison with similar average element
   ratios in the leachate of coal fly ash from Figure 1. This figure shows that post-spraying
   rainwater leached the same elements, in similar proportions, to the elements leached from
   coal fly ash in laboratory investigations [10]. This is strong evidence that the substance
   emplaced into the troposphere is coal fly ash. At a 99% confidence interval, the two sets of
   data have the same mean (T-test) and the same variance (F-test).
   Like a fingerprint, the 8-element ratios of the San Diego rainwater extract of the tropospheric-emplaced
   particulate matter match element-by-element the laboratory water extract of coal fly ash within the range of
   observations. Said another way, the tropospheric-emplaced matter has the same water-leach characteristics
   as coal fly ash for at least eight elements, which is indeed strong evidence of the identification of the
   aerosolized substance as coal fly ash. For any indicated element the difference between the rainwater
   extract and average experimental coal fly ash element extract is less than the differences observed between
   the element extracted experimentally from the various coal fly ash sources [10].
   Without mass or volume totals, statistical treatment was somewhat limited. Nevertheless, at a 99%
   confidence interval, the assemblage of elements in the rainwater and in the corresponding experimental
   leachate have identical means (T-test) and identical variances (F-test). Furthermore, the 8-element
   “fingerprint” shown in Figure 3 is comprised of elements with different chemical properties and thus
   Int. J. Environ. Res. Public Health 2015, 12 9382
   provides extremely strong validation of the hypothesis: Coal fly ash is most likely the aerosolized
   particulate sprayed in the troposphere by tanker-jets for geoengineering, weather-modification and
   climate-modification purposes.
   One limitation in the use of commercial laboratories is in their limits of detection for some
   elements. Note from Figure 2 that the experimental coal fly ash leachate element ratios span six orders
   of magnitude. When academic research laboratories, with their high sensitivity capabilities, hopefully
   repeat the post-spray rainwater measurements, additional “matched pairs” for other elements will
   doubtlessly be added to the coal fly ash “fingerprint” presented in Figure 3.
   For about fifteen years concerned individuals have sampled water, soil, and other materials in attempt
   to learn what is being sprayed into the atmosphere. From 15 May 2011 through 15 August 2011,
   a period intense tanker-jet spraying, an individual in Los Angeles, California operated a Honeywell
   model HHT081 HEPA Filter in her backyard in the vicinity of Olympic and La Cienega Boulevard, Los
   Angeles, California, 90035. Samples were collected and then transferred via chain-of-custody to
   American Scientific Laboratory, a state-of-California certified laboratory for analysis of aluminum,
   barium, and twelve trace elements by inductively coupled plasma mass spectrometry.
   Figure 4 shows concentrations of 14 chemical elements, normalized to aluminum, measured in the
   Los Angeles HEPA air filter dust for comparison with corresponding average element ratios for
   un-leached coal fly ash data (Table 1) from [10].
   Figure 4. The chemical concentrations of 14 chemical elements, normalized to aluminum,
   measured in the Los Angeles HEPA air filter dust for comparison with corresponding
   average element ratios for un-leached coal fly ash (Table 1) data from [10]. This figure
   shows the 14 elements measured in the collected filter dust occur in the same relative
   proportions as similar elements in un-leached coal fly ash from published laboratory
   investigations [10]. This is strong evidence that the substance emplaced into the
   troposphere is coal fly ash. At a 99% confidence interval, the two sets of data have the
   same mean (T-test) and the same variance (F-test).
   Int. J. Environ. Res. Public Health 2015, 12 9383
   Like a fingerprint, the 14-element ratios of the HEPA dust match well the corresponding average
   chemical element ratios of un-leached coal fly ash. As with Figure 3 data, without mass or volume
   totals, statistical treatment was somewhat limited. Nevertheless, at a 99% confidence interval, the
   assemblage of elements in the HEPA dust and in the corresponding average coal fly ash have identical
   means (T-test) and identical variances (F-test).
   Coal fly ash from difference sources vary somewhat in their relative proportions of chemical
   elements. Figure 5, a plot of the normalized high and low value for each of the 14 respective elements
   from un-leached coal fly ash [10], provides an indication of the range of variation in the coal fly ash
   material from different sources. Significantly, for any indicated element ratio in Figure 4,
   the difference between HEPA dust material and average coal fly ash composition is generally less than
   the extremes observed between high and low values of the various coal fly ash sources shown in Figure 5.
   Furthermore, the 14-element “fingerprint” shown in Figure 4 is comprised of elements with different
   chemical properties, implying a unique process, and thus further provides extremely strong validation of
   the hypothesis: Coal fly ash is most likely the aerosolized particulate sprayed in the troposphere by
   tanker-jets for geoengineering, weather-modification and climate-modification purposes.
   Figure 5. This figure is a plot of the normalized high and low value for each of the
   14 respective elements from un-leached coal fly ash [10]. It provides an indication of the
   range of variation in un-leached coal fly ash material from different sources. This natural
   variation in coal fly ash elemental compositions may help to explain the variations
   observed in Figures 3 and 4.
   Reliable observers have reported tropospheric aerosol emplacement since the late 1990s. In the
   early phases of the program one might suspect that a variety of substances were tried. At what point
   was coal fly ash chosen as the preferred substance? In the past, one of the great uncertainties about
   analyzing post-aerosol rainwater has been which elements to measure. Aluminum was commonly
   Int. J. Environ. Res. Public Health 2015, 12 9384
   measured, while barium and strontium were sometimes measured; other chemical elements were rarely
   measured. As aluminum, barium and strontium are prominent water-extracts of coal fly ash, their
   presence in post-aerosol rainwater might be taken as a 3-element fingerprint of aerosolized coal fly
   ash, albeit with much less certainty than the 8-element fingerprint shown in Figure 3. Based upon the
   3-element fingerprint, with its limited certainty, the year 2002 is the earliest data found to date
   showing simultaneous measurement of these three elements in post-aerosol rainwater [12]. Within that
   certainty-limitation, the 3-element fingerprint in post-spraying rainwater measurements indicates the
   global extent of tropospheric aerosol coal fly ash dispersing: such measurements have been made in
   the United States, Canada, France, Portugal, Germany, Australia, and New Zealand. Further, this list is
   unlikely to be exhaustive. The global extent of tropospheric coal fly ash emplacement is inferred from
   rainwater analyses reporting the three elements (aluminum, barium and strontium) that are prominent
   in the leachate of laboratory coal fly ash water-leach experiments.
   The research reported here provides strong evidence that coal fly ash is the aerosolized particulate
   sprayed in the troposphere by tanker-jets for geoengineering, weather-modification and
   climate-modification purposes. The evidence presented warrants discussion as to (1) what additional
   investigations should be undertaken to confirm further the identity of coal fly ash as the aerosolized
   particulates, (2) the consequences of troposphere-emplaced coal fly ash on public health and on Earth's
   biota, and (3) the resultant geophysical implications.
   The rainwater and dust sample collection, in San Diego and Los Angeles, respectively, took place in
   areas far removed from aerosol-polluting heavy industries under circumstances of intense and persistent
   aerial spraying of fine grain particulates that left a white haze in the sky. The tropospheric lifetime of the
   particulates was sufficiently short as to necessitate near-daily spraying, which is an argument against the
   collected samples originating far away, such as from China due to the global movement of weather.
   Whereas the “fingerprint” evidence is compelling, strongly suggesting identical processes/materials,
   additional investigations should be undertaken and, indeed, are being planned.
   Off the coast of Southern California individuals have observed tanker jets “dumping” massive
   quantities of particulate matter in relatively short bursts, colloquially called “bombs”, which disperse
   significantly before prevailing winds bring the matter to the coast line. One plan under consideration is
   to use aircraft to capture in flight some of the concentrated material, which would then be analyzed
   physically and chemically, and as well be subjected to leaching experiments.
   In the 1970s acid rain [13] liberated aluminum in a chemically mobile form from otherwise inert
   sources, such as mine tailings, that posed an environmental health threat to a host of organisms [14,15].
   Forest die-offs, reduced survival or impaired reproduction of aquatic invertebrates, fish, and
   amphibians were directly connected to aluminum toxicity, while indirect effects on birds and mammals
   were also identified [16]. Tropospheric aerosolized coal fly ash poses a similar environmental health
   threat without necessarily requiring an acid environment. In the experiments by Moreno et al. [10],
   distilled water led to aluminum extraction while other chemical reactions yielded leachate pH values in
   the range 6.2–12.5. The pH of post-spraying rainwater is a function of the composition of the coal fly
   ash and the degree of its equilibration with atmospheric water. Natural rainwater has an acidic pH of
   about 5.7 due to interaction with atmospheric CO2 [17]. The pH of the analyzed post-spraying San
   Diego rainwater was 5.2 whereas in instances elsewhere it has been observed as high as 6.8.
   Int. J. Environ. Res. Public Health 2015, 12 9385
   Long exposure to air pollution particulates, not necessarily coal fly ash, in sizes ≤ 2.5µm (PM2.5) is
   associated with morbidity and premature mortality [18,19]. One may therefore reasonably conclude
   that aerosolized coal fly ash, at least the PM2.5 component, is detrimental to human health.
   The ultra-fine particles of aerosolized coal fly ash do not remain at tanker-jet operational altitudes:
   they mix with and pollute the air people breathe. Tropospheric aerosol coal fly ash can potentially
   endanger humans through two primary routes: (1) ingestion of rainwater-extract of coal fly ash toxins,
   directly or after concentration by evaporation and (2) particulate intake through inhalation or through
   contact with the eyes or skin [20]. In the latter instance, harm to humans can arise from in situ
   body-fluid extraction of coal fly ash toxins [21] as well as from the consequences of tissue contact [22].
   Coal fly ash that is PM2.5 is readily entrained in terminal airways and alveoli and retained in the lungs
   for long periods of time; the small grain size enables it to penetrate and reach deep within the airways
   where it can cause inflammation and pulmonary injury [23].
   Coal fly ash contains a host of potentially leachable toxins, including aluminum, arsenic, barium,
   beryllium, boron, cadmium, chromium (III), chromium (IV), cobalt, lead, manganese, mercury,
   selenium, strontium, thallium, thorium, and uranium. Coal fly ash has been described as being more
   radioactive than nuclear waste [24]. Moreover, many of the most toxic elements are enriched in the
   PM2.5 component of coal fly ash [25]. Whether or not the coal fly ash used for geoengineering is
   selectively enriched in PM2.5 is not known, but enrichment in the small particle size fraction would be
   advantageous in yielding greater surface area for sunlight reflection.
   The extent of adverse health consequences from aerosolized coal fly ash depends on a variety of
   factors including age, physical condition, individual susceptibility, concentration and exposure
   duration. Moreover, some toxic elements from tropospheric spraying of coal fly ash, in addition to
   direct bodily input by inhalation or transdermal infusion, may be concentrated by processes in nature.
   Arsenic, for example, one of the coal fly ash toxins, poses the greatest health threat in its inorganic
   form. Arsenic can be taken up by a variety of organisms and, like mercury, can be passed up the food
   chain [26]. Arsenic can be involved with hypertension-related cardiovascular disease [27], cancer [28],
   stroke [29], chronic lower respiratory diseases [30] and diabetes [31]. Arsenic leached from coal fly
   ash taken in by pregnant women can crossover the placenta to the fetus [32]. Concentration and
   exposure duration increase likelihood of this happening.
   The evidence presented here of deliberate, widespread and pervasive spraying of coal fly ash into
   the troposphere, which mixes with the air people breathe, opens new research possibilities into the
   physiological effects of long-term exposure to a substance that potentially releases multifarious toxins
   upon exposure to internal body fluids. Those subjects are beyond the scope of the present article.
   Nevertheless, mention should be made of perhaps the least appreciated coal fly ash potentially
   water-extracted toxin, chemically mobile aluminum.
   Although aluminum is abundant in the Earth's crust, it is highly immobile. Consequently,
   our planet's biota, including humans, have not developed natural defense mechanisms for exposure to
   chemically mobile aluminum. It is a matter of grave concern that aluminum in a chemically mobile
   form can be readily extracted from coal fly ash with rainwater or in situ with body fluids. Aluminum is
   implicated in such neurological diseases as autism spectrum disorder (ASD), Alzheimer's disease,
   Parkinson's disease, and attention deficit hyperactivity disorder (ADHD) [33–37] all of which have
   Int. J. Environ. Res. Public Health 2015, 12 9386
   markedly increased in recent years. Aluminum is thought to impair fertility in men [38] and is also
   implicated in neurological disorders of bees and other creatures [39–41].
   If in fact some instances of neurological diseases are related to weather-modification activities
   during the last two decades involving the tropospheric coal fly ash aerosols, then the recent ramp-up in
   tanker-jet spraying, as witnessed by this author in San Diego, will likely cause a sharp spike in their
   occurrence. Epidemiological investigations of wide-ranging scope, including for example childhood
   and elderly disorders and birth defects, may begin to shed light on the human toll extracted by spraying
   coal fly ash into the troposphere. Those investigations should especially consider airline flight crews
   and frequent airline travelers who breathe the air at nearly the same altitude as the spraying.
   The near-daily intense aerial spraying over San Diego witnessed by the author is part of a
   multinational Western, if not global, program that has been observed for a number of years in United
   States, Canada, Europe, Australia and New Zealand, but never acknowledged publically by officials.
   Without public candor it is difficult to know the underlying motivations and the range of specific
   activities involved. One thing seems certain: the potential damage to public health and the environment
   is likely to be unprecedented in its planetary scope.
   The process of burning coal concentrates the impurities in coal fly ash, an unnatural anhydrous chemical
   complex whose environmental health hazards are well-known. For decades individuals and organizations
   have fought long and hard for regulations requiring sequestration of this hazardous industrial waste
   product. So what, one might ask, is the reason for the current, widespread, pervasive spraying of coal fly
   ash into the troposphere with its potential harm to public health and the environment?
   Since the United Nations Intergovernmental Panel on Climate Change (IPCC) was established in
   1988 there has been much interest in global warming, which is perceived as a security threat.
   Geoengineering offers two basic approaches to the problem of global warming: Remove and trap
   carbon dioxide, or block sunlight from reaching the Earth. Trapping carbon dioxide is a difficult,
   prohibitively expensive, undeveloped technology. Blocking sunlight is almost universally recognized
   by geoengineers as being relatively inexpensive, easy to implement, and moreover has a precedent in
   nature: major volcanic eruptions inject ash into the upper atmosphere (stratosphere) which may remain
   suspended for a year or more, dimming sunlight and momentarily cooling Earth.
   While academicians debate geoengineering as an activity that might potentially be needed in the
   future [2,3], evidence suggests that Western governments/militaries moved ahead with a full scale
   operational geoengineering program. But instead of mining and milling rock to produce artificial
   volcanic ash in sufficient volumes to cool the planet, they adopted a low-cost, pragmatic alternative,
   but one with consequences far more dire to life on Earth than global warming might ever be, and used
   coal combustion fly ash. To make matters worse, instead of placing the material high into the
   stratosphere, where there is minimal mixing and the substance might remain suspended for a year or
   more, they opted to spray coal fly ash into the lower atmosphere, the troposphere, which mixes with
   the air people breathe and gets rained down to ground.
   Aside from the serious potential toxicity ramifications on public health and Earth's biota that derive
   directly from aerosolized emplacement of coal fly ash into the troposphere, such pervasive,
   widespread, tanker-jet spraying affects weather and Earth's heat balance in ways that act in opposition
   to cooling the Earth. Those who reside in locations where natural cloud cover is rare, like San Diego,
   notice the rapid cooling after the sun goes down, except on cloudy days when heat is retained. During
   Int. J. Environ. Res. Public Health 2015, 12 9387
   the daytime coal fly ash clouds may block sunlight, but at night may retard heat loss from the Earth,
   act to prevent rainfall, and contribute to global warming. Nighttime tanker-jet spraying, presumably to
   the hide the activity from public view, further retards heat loss.
   There is yet another consequence of tropospheric coal ash spraying that is contrary to cooling the
   Earth and has potentially far-reaching adverse ecological and public health implications: weather
   modification and concomitant disruption of habitats and food sources. As reported by NASA, “Normal
   rainfall droplet creation involves water vapor condensing on particles in clouds. The droplets
   eventually coalesce together to form drops large enough to fall to Earth. However, as more and more
   pollution particles (aerosols) enter a rain cloud, the same amount of water becomes spread out. These
   smaller water droplets float with the air and are prevented from coalescing and growing large enough
   for a raindrop. Thus, the cloud yields less rainfall over the course of its lifetime compared to a clean
   (non-polluted) cloud of the same size” [42]. In addition to preventing water droplets from coalescing
   and growing large enough to fall to Earth, coal fly ash, which formed under anhydrous conditions, will
   hydrate, trapping additional moisture thus further acting to prevent rainfall. That may cause drought in
   some areas, floods in others, crop failure, forest die-offs, and adverse ecological impacts, especially in
   conjunction with the chemically-mobile-aluminum contamination from coal fly ash. The consequences
   ultimately may have devastating effects on habitats and reduce human food production.
4. Conclusions
   The original research reported here provides strong evidence for the correctness of the hypothesis:
   Coal fly ash is most likely the aerosolized particulate sprayed in the troposphere by tanker-jets for
   geoengineering, weather-modification and climate-modification purposes. That evidence is based upon
   the discovery that: (1) the assemblage of 8 elements in rainwater and in the corresponding
   experimental leachate are essentially identical. At a 99% confidence interval, they have identical
   means (T-test) and identical variances (F-test); and, (2) the assemblage of 14 elements in the HEPA
   dust and in the corresponding average un-leached coal fly ash are likewise essentially identical.
   Evidence indicates that tropospheric spraying of coal fly ash (1) has been taking place throughout
   the 21st century, (2) on an international scale, and (3) with significant ramping-up since about 2013.
   Throughout that period of time there has been a program of well-orchestrated disinformation, but no
   public disclosure, no informed consent, and no public health warnings.
   The profound implications on environmental health include exposing humans and Earth's other
   biota to: (1) chemically mobile aluminum, implicated in neurological disorders and botanic demise;
   (2) exposure to toxic heavy metals and radioactive elements; (3) preventing rainfall with concomitant
   loss of food production and habitats; and, (4) possibly contributing to global warming with
   concomitant arctic melting.
   More than a half century ago Rachel Carson called the world's attention to the unintended
   consequences of herbicides and pesticides widely employed by agriculture. Instead of turning a blind
   eye, people everywhere became motivated to stop the worst of this environmental onslaught. Today we
   are fully aware of the vast interconnected web of dependencies and symbioses that comprise life on
   our planet. Earth exists in a state of dynamic biological, chemical, and physical equilibrium whose
   complexity far exceeds the understanding of contemporary science. The pervasive tropospheric
   Int. J. Environ. Res. Public Health 2015, 12 9388
   spraying of coal fly ash threatens this equilibrium, whose delicacy or whose resilience we cannot
   quantify. Human health is at risk as is Earth's biota. Are we to remain silent? Or will we exercise our
   primal right to speak in our own defense as a species and question the sanity of emplacing coal fly ash
   in Earth's perpetually moving atmosphere?
