The Triumph of Rush Limbaugh and Me
As a conservative, and back in 1988, while working as a college professor at a college where conservatives were ignorant slime who should hide under rocks, I heard Rush Limbaugh for the first time, and realized I was not alone. Over the years, his has been the one voice that has always sustained me, and, once in a while, has moved me to tears as he eloquently championed the hope and spirit of America and of her true heroes. As his leftist, hate-America, critics tried to shut him up, first by demonizing him, then by subsidizing his radio competitors and trying to boycott his advertisers, and, most recently, by siccing an unscrupulous Democrat prosecutor to hound him unmercifully about his addiction arising out of his serious and painful health problems, I have cheered him and prayed for him.
Today, as I read the following article, I breathed a sigh of relief and raised my glass. Rush’s ordeal appears to be over.
Persecution of Rush Limbaugh suffers a blow
The American Thinker (Source: Roy Black)
When the political history of this era is written by observers detached from current passions, there is no doubt that Rush Limbaugh will accorded a prominent place in explaining the rise of conservatism. He is without question the single most influential media figure in the entire history of American broadcasting.
When the history of Rush Limbaugh is examined by objective historians of the future, the shameful persecution he has endured will no doubt the subject of many a doctoral dissertation. Many of them will focus on the shameful persecution he has endured at the hands of a partisan prosecutor.
How was it possible that such an important figure could be the only person ever prosecuted in Florida for the specific behavior alleged? And how was it possible the he alone was subjected to an attempted violation of doctor-patient confidentiality?
At last, a sensible ruling has been issued which recognizes that Rush Limbaugh, no less than any other American, is entitled to have his doctor-patient relationship unmolested by the questions of prosecutors directed at his physician, in search of an offense on which to indict him. Judge David Crow prohibited prosecutors from asking Rush’s doctors about his medical treatment and condition or information he shared with his doctors during his care and treatment.
The fact is that we know that Rush Limbaugh developed a dependency on prescription painkillers, and that he eventually obtained some without benefit of prescription. This is neither healthy nor legal, and I do not endorse such behavior. But in the wake of excruciating pain from a medical condition, and under pressure to continue to captivate a huge radio audience while losing his hearing, it is a rather understandable transgression.
When other well-known people have developed presciption drug dependencies, they have been smothered in support. Betty Ford has a clinic named after her. But Rush Limbaugh, and Rush Limbaugh alone, has been pursued by an obsessed political enemy using his office as prosecutor to take out the most important conservative in the mass media.
Congratulations are due to Rush and to his lawyer Roy Black. It is time for the persecution of Rush to end. Now that the prosecutorial fishing expedition has been ruled out of bounds, the DA should pursue real criminals who harm the public.

I think your dislike of Rush clouds your judgment. Show me one person in similar circumstances who has been so doggedly pursued by Florida authorities including multiple attempts and appeals to get at his medical records.
Thank God for Rush! He cuts through the elite media propaganda,which is run by Liberal lapdogs, to tell it like it is. He's like a shinning light. They won't go after the Jesse Jacksons though. It's okay for Jesse Jackass to cheat on his income tax, or shake down big industry while the so-called powers in this country look the other way and go after Rush or Karl Rove and Scooter Libby.
Rush Limbaugh's views simply are not factual. For systematic lie vs. truth comparison on just one topic - the environment, see:

Introduction:
Rush Limbaugh's best-selling books The Way Things Ought to Be
and See, I Told You So are full of statements on the environment
that are misleading, distorted, and factually incorrect. Indeed,
Limbaugh's claims often fly in the face of carefully considered
scientific evidence, and put him in opposition to the views of the
most eminent scientific experts, as reflected in the conclusions of
such esteemed bodies as the National Academy of Sciences and
the World Meteorological Organization. Though Limbaugh likes to
frame the debate as a contest between him and the "environmental
wackos", it is really Limbaugh's word against the overwhelming tide
of scientific knowledge.
Unfortunately, his fallacies have created a great deal of confusion
and have perpetuated the misunderstanding of a number of critical
issues. It is important that Limbaugh's disinformation campaign be
confronted directly and that the resulting misconceptions be cleared
up.
Here we present several examples of erroneous statements from
Limbaugh's books, followed by the actual scientific facts. In each
instance, we have included sources in the scientific and
professional literature, unlike Limbaugh, who offers little or no
evidence to back up his claims.
Chlorofluorocarbons and Ozone Depletion:
RUSH FICTION:
Limbaugh proposes that environmental "alarmists and prophets of
doom" have exaggerated the problem of ozone depletion,
suggesting that it has been limited to "occasional reduced levels of
ozone over Antarctica." 1/
SCIENTIFIC FACT:
Substantially reduced levels of ozone have been measured over
most of the globe, including North America, Europe, and elsewhere.
In fact, scientists have observed a thinning of the ozone layer at all
latitudes outside the tropics. By 1991, the depletion over North
America averaged nearly 5 percent. 2/ Since 1991, ozone depletion
has further intensified. 3/
RUSH FICTION:
"Mount Pinatubo in the Philippines spewed forth more than a
thousand times the amount of ozone-depleting chemicals in one
eruption than all the fluorocarbons manufactured by wicked,
diabolical, and insensitive corporations in history. . . . Conclusion:
mankind can't possibly equal the output of even one eruption from
Pinatubo, much less billion years' worth, so how can we destroy
ozone?" 4/
SCIENTIFIC FACT:
Limbaugh's numbers are completely off-base. Volcanoes emit two
sorts of ozone-depleting compounds. One is hydrochloric acid, but
the amount of this chemical in the stratosphere, measured before
and after Pinatubo's eruption in 1991, was found to be largely
unchanged. 5/
The other ozone-depleting chemical emitted by Pinatubo, sulfur
dioxide, is converted in the stratosphere into tiny particles which,
acting in combination with man-made chlorofluorocarbons (CFC's),
temporarily increased the rate of ozone depletion by several
percentage points during 1992 and 1993. 6/ Nevertheless, nearly
all the particles resulting from the Mt. Pinatubo eruption have
already washed out of the atmosphere, unlike CFC's, which remain
in the stratosphere for as long as a century. 7/
Cumulatively speaking, Pinatubo's destructive effect on the ozone
layer has been about fifty times less than that of CFC's, rather than
a thousand times greater, as Limbaugh claims. Thus, his estimate
is off by a factor of fifty thousand.
RUSH FICTION:
What "environmental wackos . . . really want to do is attack our way
of life" in the effort to limit CFC's. "Their primary enemy:
capitalism." 8/
SCIENTIFIC FACT:
Limbaugh ignores the fact that the conservative Reagan
administration signed onto the Montreal Protocol, the international
agreement to restrict CFC's, and that crucial support for the
measure came from some of the largest manufacturers of these
chemicals, who, like Ronald Reagan, are hardly enemies of
capitalism. Although many of these corporations initially resisted
action when the ozone problem was discovered, Dupont, Allied
Signal, and other domestic producers of CFC's have long favored
strong restrictions concerning their production and use. Indeed,
Dupont proposed a global ban of CFC's before European or United
States governments did. 9/
RUSH FICTION:
"In just one day in January [1992], NASA measured the amount of
chlorine and another gas in the atmosphere of the Northern
Hemisphere and found an unusually high level compared to normal.
. . . There were headlines for days about an ozone hole in the
atmosphere above North America. Senator Al Gore . . . predicted
that President Bush would soon come around on all this because of
the 'ozone hole over Kennebunkport,' despite the fact there was no
such thing. . . . Within a few weeks, it was learned that most of the
unusual measurements could be attributed to Mount Pinatubo's
eruption, a fact the agenda-oriented scientific community attempted
to ignore." 10/
SCIENTIFIC FACT:
Limbaugh's last statement is absolutely false. The measurements to
which he refers, of extremely high levels of chlorine monoxide, were
made by NASA only six months after Pinatubo's eruption and in a
particular region of the Arctic stratosphere that was at the time
unaffected by the volcanic emissions. Furthermore, large amounts
of these chemicals were measured throughout the month of
January, not just on one day, as Limbaugh asserts. 11/
As for the rest, the condition of the ozone layer in January of 1992
was a great deal more complex than Limbaugh's account would
suggest. Indeed, many scientists were disturbed by the high
chlorine monoxide levels. For a very large depletion to occur,
however, the Arctic stratosphere would have had to remain cold for
several more weeks, as it often does that time of year. Instead, a
sudden warming occurred the following month, so the damage to
the ozone layer never became as severe as originally feared. If it
had, the depletion might well have reached 20 to 30 percent in the
lower stratosphere, rather than the 10 to 15 percent that was
recorded. Indeed, such large depletions could occur over parts of
Northern Europe and Canada during any winter, and may do so in
the future. 12/
In his most recent book, See, I Told You So, Limbaugh returns to
the subject of ozone depletion. This time, he discusses the
implications of a possible prehistoric supernova that may have
damaged the atmosphere:
RUSH FICTION:
"Scientists say a supernova 340,000 years ago disrupted 10
percent to 20 percent of the ozone layer, causing sunburn in
prehistoric man. Wait a minute - I thought only man could destroy
the ozone. . . . And if prehistoric man merely got a sunburn, how is
it that we are going to destroy the ozone layer with our air
conditioners and underarm deodorants and cause everybody to get
cancer? Obviously we're not...and we can't ...and it's a hoax." 13/
SCIENTIFIC FACT:
The report of a prehistoric supernova exploding close enough to the
Earth to have possibly affected its ozone layer, thousands of years
ago, though of doubtful relevance to Limbaugh's argument, was
published in the British journal Nature and followed up by the New
York Times in 1993. As quoted in the Times, Dr. Neil Gehrels, one
of the authors of the report, clearly did not mean to minimize the
possibility that the ozone loss that may have resulted would have
damaged whatever forms of life were roaming the planet. Indeed,
he was reported as saying that the effects of such an ozone
depletion may well "have impaired the health of human beings and
other creatures..." 14/
RUSH FICTION:
"Even The Washington Post - that haven of liberal mythology -
published a front-page story on April 15, 1993, that dismissed most
of the fears about the so-called ozone hole... had this to say: 'In
fact, researchers say the problem appears to be heading toward
solution before they can find any solid evidence that serious harm
was or is being done.'" 15/
SCIENTIFIC FACT:
Limbaugh neglects to mention that the problem of ozone depletion
appears to be heading towards solution only as a result of
international agreements to restrict the production and use of
CFC's. Thanks to these agreements, the ozone layer should return
to near-normal levels around the year 2045. Before 1998,
however, stratospheric ozone is expected to become thinner every
year, and the amount of ultraviolet radiation reaching the Earth to
increase, assuming other influences remain constant. 16/
Although the consequences of increased ultraviolet exposure for
plants and marine life are just beginning to be explored, the
damage to humans from long-term exposure is well known. In
many parts of the globe, ozone depletion is likely to cause a rise in
rates of skin cancer, particularly non-melanoma cancers, which, due
to lifestyle factors, are already at record levels. 17/
RUSH FICTION:
"A few days later, the authoritative journal Science published a
story headlined 'Ozone Takes Nose Dive After the Eruption of Mt.
Pinatubo.' It pointed out that the ozone layer should show
significant signs of recovery by 1994. But have you heard Algore
(sic) or any other ozone alarmist step up and admit that he or she
perpetuated (sic) a fraud on the American people?" 18/
SCIENTIFIC FACT:
Indeed, the ozone layer did not thin as much in 1994 as it did in
1993, due to the washing out of emissions from Mount Pinatubo
(see above). Nevertheless, as Science magazine pointed out in a
recent issue, this improvement is only temporary, since levels of
"atmospheric chlorine will continue to increase until controls on
CFC emissions take hold late in this decade. Pinatubo or no,
things will get worse." 19/
Global Warming and the Greenhouse Effect
Global warming is another topic about which Limbaugh attempts to
mislead his readers, despite the international scientific consensus
on many aspects of this issue. This consensus is reflected in the
findings of the top researchers in the field, as published in the peer-
reviewed scientific literature, and the conclusions of the
Intergovernmental Panel on Climate Change (IPCC), the
international scientific panel assessing climate change, which
consists of a network of 2,500 experts worldwide. The IPCC has
issued two reports clearly stating and then reaffirming that the
Earth's climate will warm due to the buildup of man-made
greenhouse gases. 20/ In 1992, the National Academy of Sciences
published its own report, concluding that "greenhouse warming
poses a potential threat sufficient to merit prompt responses." 21/
Instead of taking on the international scientific community directly,
however, Limbaugh chooses to attack Vice-President Al Gore, and
his book Earth in the Balance.
RUSH FICTION:
"Algore's (sic) book is full of calculated disinformation. For
instance, he claims that 98 percent of scientists believe global
warming is taking place. However a Gallup poll of scientists
involved in global climate research shows that 53 percent do not
believe that global warming has occurred, 30 percent say they don't
know, and only 17 percent are devotees of this dubious theory." 22/
SCIENTIFIC FACT:
These numbers, apparently lifted from a George Will syndicated
column of September 3, 1992, 23/ are supposed to reflect the
findings of a Gallup poll taken in late 1991 to ascertain the opinions
of research scientists concerning global warming. Even though
polling is of doubtful relevance for determining the scientific truth of
any proposition, it should be pointed out that nowhere in the actual
poll results are there figures that resemble those cited by Will or
Limbaugh.
Instead, the Gallup poll found that a substantial majority of the
scientists polled, 66 percent, believed that human-induced global
warming was already occurring. Only 10 percent disagreed, and
the remainder were undecided.
Moreover, the 98 percent figure appears in the context of Al Gore's
book to refer to the percentage of scientists who believe that
human-induced global warming is a legitimate threat, not, as
Limbaugh frames it, to the number of those who argue that it is
already in effect. In fact, the Gallup poll seems to bear out Gore's
estimate as well, finding that only 2 percent of the scientists polled
believed that there was no chance that substantial, human-caused
warming will occur over the next fifty to one hundred years. 24/
RUSH FICTION:
"Algore told the Washington Times on May 19, 1993: 'That
increased accumulations of greenhouse gases, particularly CO2,
cause global warming, there is no longer any serious debate.
There are a few naysayers far outside the consensus who try to
dispute that. They are not really taken seriously by the mainstream
scientific community.' Yet we saw in the last chapter that there is
nothing resembling a consensus on this issue among scientists who
have some expertise in this area. In fact, a majority clearly does
not believe global warming has occurred." 25/
SCIENTIFIC FACT:
See the preceding item. Furthermore, even the most publicized
and vehement of scientific naysayers, such as Pat Michaels of the
University of Virginia, agree that increased accumulation of carbon
dioxide will eventually cause global warming. What they disagree
about is how much warming will occur over what period of time. 26/
RUSH FICTION:
"...back at the time of the first Earth Day, the big concern wasn't
global warming, it was global cooling. . . . the view of
most environmentalists for years after." 27/
SCIENTIFIC FACT:
Although the Earth has warmed by about one degree Fahrenheit
over the past hundred years, this warming has not occurred
uniformly. In particular, during the period from 1940 to 1970, the
Northern Hemisphere stopped warming and may have even cooled
slightly. 28/ This hiatus in the long-term trend contributed to
concerns that the Earth was about to cool significantly, possibly due
to the increased amount of soot and other particulates in the
atmosphere.
However, warming resumed again in the 1970's and the nine
warmest years on record have all occurred since 1980. 29/ Recent
calculations indicate that the greenhouse effect will outrun the
effects of particulate cooling in the future, although the
accumulation of particulates in the atmosphere may slow the overall
rate of warming. 30/
RUSH FICTION:
"A fact you never hear the environmentalist wacko crowd
acknowledge is that 96 percent of the so-called 'greenhouse' gases
are not created by man, but by nature." 31/
SCIENTIFIC FACT:
This is an obvious straw man set up by Limbaugh. It is true that the
greenhouse effect is, by and large, a natural phenomenon,
produced by gases in the atmosphere such as carbon dioxide and
water vapor that have warmed the Earth for eons, making its
climate moderate enough to support life as we know it. Without
these gases, Earth would be forty to sixty degrees colder,
essentially a frigid desert. 32/
However, in nature these gases usually remain in balance, leading
to a stable climate, while the greenhouse gases added by humans
over the last two hundred years have accumulated to the point that
the amount of carbon dioxide in the atmosphere, for example, is
now more than 25 percent above what it had been for the previous
10,000 years. (Scientists have direct evidence of this data, from
measurements of air bubbles trapped in polar ice cores.) 33/ The
scientific consensus is that the accumulation of carbon dioxide and
other gases due to human activity will alter the climate substantially,
warming the globe by three to eight degrees Fahrenheit over the
next century. 34/
In 1997 during the Clinton administration, the US Senate voted 95 to 0 to reject the Kyoto Treaty. Rarely in our nation's history has there been a unanimous vote on anything. Perhaps studies such as this one had something to do with it: (this analysis is extensively supported with data and charts which would not reproduce here. to see the charts go to http://www.oism.org/pproject/s33p36.htm
Environmental Effects of Increased Atmospheric Carbon Dioxide

ABSTRACT
A review of the research literature concerning the environmental consequences of increased levels of atmospheric carbon dioxide leads to the conclusion that increases during the 20th Century have produced no deleterious effects upon global weather, climate, or temperature. Increased carbon dioxide has, however, markedly increased plant growth rates. Predictions of harmful climatic effects due to future increases in minor greenhouse gases like CO2 are in error and do not conform to current experimental knowledge.
Summary
World leaders gathered in Kyoto, Japan, in December 1997 to consider a world treaty restricting emissions of ''greenhouse gases,'' chiefly carbon dioxide (CO2), that are thought to cause ''global warming'' severe increases in Earth's atmospheric and surface temperatures, with disastrous environmental consequences. Predictions of global warming are based on computer climate modeling, a branch of science still in its infancy. The empirical evidence actual measurements of Earth's temperature shows no man-made warming trend. Indeed, over the past two decades, when CO2 levels have been at their highest, global average temperatures have actually cooled slightly.
To be sure, CO2 levels have increased substantially since the Industrial Revolution, and are expected to continue doing so. It is reasonable to believe that humans have been responsible for much of this increase. But the effect on the environment is likely to be benign. Greenhouse gases cause plant life, and the animal life that depends upon it, to thrive. What mankind is doing is liberating carbon from beneath the Earth's surface and putting it into the atmosphere, where it is available for conversion into living organisms.
Rise In Atmospheric Carbon Dioxide
The concentration of CO2 in Earth's atmosphere has increased during the past century, as shown in figure 1 (1).
•
Figure 1: Atmospheric CO2 concentrations in parts per million by volume, ppm, at Mauna Loa, Hawaii. These measurements agree well with those at other locations (1). Periodic cycle is caused by seasonal variations in CO2 absorption by plants. Approximate global level of atmospheric CO2 in 1900 and 1940 is also displayed (2).
The annual cycles in figure 1 are the result of seasonal variations in plant use of carbon dioxide. Solid horizontal lines show the levels that prevailed in 1900 and 1940 (2). The magnitude of this atmospheric increase during the 1980s was about 3 gigatons of carbon (Gt C) per year (3). Total human CO2 emissions primarily from use of coal, oil, and natural gas and the production of cement are currently about 5.5 GT C per year.
To put these figures in perspective, it is estimated that the atmosphere contains 750 Gt C; the surface ocean contains 1,000 Gt C; vegetation, soils, and detritus contain 2,200 Gt C; and the intermediate and deep oceans contain 38,000 Gt C (3). Each year, the surface ocean and atmosphere exchange an estimated 90 Gt C; vegetation and the atmosphere, 60 Gt C; marine biota and the surface ocean, 50 Gt C; and the surface ocean and the intermediate and deep oceans, 100 Gt C (3).
•
Figure 2: Surface temperatures in the Sargasso Sea (with time resolution of about 50 years) ending in 1975 as determined by isotope ratios of marine organism remains in sediment at the bottom of the sea (7). The horizontal line is the average temperature for this 3,000 year period. The Little Ice Age and Medieval Climate Optimum were naturally occurring, extended intervals of climate departures from the mean.
So great are the magnitudes of these reservoirs, the rates of exchange between them, and the uncertainties with which these numbers are estimated that the source of the recent rise in atmospheric carbon dioxide has not been determined with certainty (4). Atmospheric concentrations of CO2 are reported to have varied widely over geological time, with peaks, according to some estimates, some 20-fold higher than at present and lows at approximately 18th-Century levels (5).
The current increase in carbon dioxide follows a 300-year warming trend: Surface and atmospheric temperatures have been recovering from an unusually cold period known as the Little Ice Age. The observed increases are of a magnitude that can, for example, be explained by oceans giving off gases naturally as temperatures rise. Indeed, recent carbon dioxide rises have shown a tendency to follow rather than lead global temperature increases (6).
There is, however, a widely believed hypothesis that the 3 Gt C per year rise in atmospheric carbon dioxide is the result of the 5.5 Gt C per year release of carbon dioxide from human activities. This hypothesis is reasonable, since the magnitudes of human release and atmospheric rise are comparable, and the atmospheric rise has occurred contemporaneously with the increase in production of CO2 from human activities since the Industrial Revolution.

Solar magnetic cycle lengths right axis and lighter line (10). The shorter the magnetic cycle length, the more active, and hence brighter, the sun.
Atmospheric And Surface Temperatures
In any case, what effect is the rise in CO2 having upon the global environment? The temperature of the Earth varies naturally over a wide range. Figure 2 summarizes, for example, surface temperatures in the Sargasso Sea (a region of the Atlantic Ocean) during the past 3,000 years (7). Sea surface temperatures at this location have varied over a range of about 3.6 degrees Celsius (ºC) during the past 3,000 years. Trends in these data correspond to similar features that are known from the historical record.
•
Figure 4: Annual mean surface temperatures in the contiguous United States between 1895 and 1997, as compiled by the National Climate Data Center (12). Horizontal line is the 103-year mean. The trend line for this 103-year period has a slope of 0.022 ºC per decade or 0.22 ºC per century. The trend line for 1940 to 1997 has a slope of 0.008 ºC per decade or 0.08 ºC per century.
For example, about 300 years ago, the Earth was experiencing the ''Little Ice Age.'' It had descended into this relatively cool period from a warm interval about 1,000 years ago known as the ''Medieval Climate Optimum.'' During the Medieval Climate Optimum, temperatures were warm enough to allow the colonization of Greenland. These colonies were abandoned after the onset of colder temperatures. For the past 300 years, global temperatures have been gradually recovering (11). As shown in figure 2, they are still a little below the average for the past 3,000 years. The human historical record does not report ''global warming'' catastrophes, even though temperatures have been far higher during much of the last three millennia.
What causes such variations in Earth's temperature? The answer may be fluctuations in solar activity. Figure 3 shows the period of warming from the Little Ice Age in greater detail by means of an 11-year moving average of surface temperatures in the Northern Hemisphere (10). Also shown are solar magnetic cycle lengths for the same period. It is clear that even relatively short, half-century-long fluctuations in temperature correlate well with variations in solar activity. When the cycles are short, the sun is more active, hence brighter; and the Earth is warmer. These variations in the activity of the sun are typical of stars close in mass and age to the sun (13).
Figure 4 shows the annual average temperatures of the United States as compiled by the National Climate Data Center (12). The most recent upward temperature fluctuation from the Little Ice Age (between 1900 and 1940), as shown in the Northern Hemisphere record of figure 3, is also evident in this record of U.S. temperatures. These temperatures are now near average for the past 103 years, with 1996 and 1997 having been the 42nd and 60th coolest years.
•
Figure 5: Radiosonde balloon station measurements of global lower tropospheric temperatures at 63 stations between latitudes 90 N and 90 S from 1958 to 1996 (15). Temperatures are three-month averages and are graphed as deviations from the mean temperature for 1979 to 1996. Linear trend line for 1979 to 1996 is shown. The slope is minus 0.060 ºC per decade.
Especially important in considering the effect of changes in atmospheric composition upon Earth temperatures are temperatures in the lower troposphere at an altitude of roughly 4 km. In the troposphere, greenhouse-gas-induced temperature changes are expected to be at least as large as at the surface (14). Figure 5 shows global tropospheric temperatures measured by weather balloons between 1958 and 1996. They are currently near their 40-year mean (15), and have been trending slightly downward since 1979.
•
Figure 6: Satellite Microwave Sounding Unit, MSU, measurements of global lower tropospheric temperatures between latitudes 83 N and 83 S from 1979 to 1997 (17,18). Temperatures are monthly averages and are graphed as deviations from the mean temperature for 1979 to 1996. Linear trend line for 1979 to 1997 is shown. The slope of this line is minus 0.047 ºC per decade. This record of measurements began in 1979.
•
Figure 7: Global radiosonde balloon temperature (light line) (15) and global satellite MSU temperature (dark line) (17,18) from figures 5 and 6 plotted with 6-month smoothing. Both sets of data are graphed as deviations from their respective means for 1979 to 1996. The 1979 to 1996 slopes of the trend lines are minus 0.060 ºC per decade for balloon and minus 0.045 for satellite.
Since 1979, lower-tropospheric temperature measurements have also been made by means of microwave sounding units (MSUs) on orbiting satellites (16). Figure 6 shows the average global tropospheric satellite measurements (17,18) the most reliable measurements, and the most relevant to the question of climate change.
Figure 7 shows the satellite data from figure 6 superimposed upon the weather balloon data from figure 5. The agreement of the two sets of data, collected with completely independent methods of measurement, verifies their precision. This agreement has been shown rigorously by extensive analysis (19, 20).
While tropospheric temperatures have trended downward during the past 19 years by about 0.05 ºC per decade, it has been reported that global surface temperatures trended upward by about 0.1 ºC per decade (21, 22). In contrast to tropospheric temperatures, however, surface temperatures are subject to large uncertainties for several reasons, including the urban heat island effect (illustrated below).
During the past 10 years, U.S. surface temperatures have trended downward by minus 0.08 ºC per decade (12) while global surface temperatures are reported increased by plus 0.03 ºC per decade (23). The corresponding weather-balloon and satellite tropospheric 10-year trends are minus 0.4 ºC and minus 0.3 ºC per decade, respectively.
•
Figure 8: Tropospheric temperature measurements by satellite MSU for North America between 30º to 70º N and 75º to 125º W (dark line) (17, 18) compared with the surface record for this same region (light line) (24), both plotted with 12-month smoothing and graphed as deviations from their means for 1979 to 1996. The slope of the satellite MSU trend line is minus 0.01 ºC per decade, while that for the surface trend line is plus 0.07 ºC per decade. The correlation coefficient for the unsmoothed monthly data in the two sets is 0.92.
Disregarding uncertainties in surface measurements and giving equal weight to reported atmospheric and surface data and to 10 and 19 year averages, the mean global trend is minus 0.07 ºC per decade.
In North America, the atmospheric and surface records partly agree (20 and figure 8). Even there, however, the atmospheric trend is minus 0.01 per decade, while the surface trend is plus 0.07 ºC per decade. The satellite record, with uniform and better sampling, ismuch more reliable.
The computer models on which forecasts of global warming are based predict that tropospheric temperatures will rise at least as much as surface temperatures (14). Because of this, and because these temperatures can be accurately measured without confusion by complicated effects in the surface record, these are the temperatures of greatest interest. The global trend shown in figures 5, 6 and 7 provides a definitive means of testing the validity of the global warming hypothesis.

The Global Warming Hypothesis
There is such a thing as the greenhouse effect. Greenhouse gases such as H2O and CO2 in the Earth's atmosphere decrease the escape of terrestrial thermal infrared radiation. Increasing CO2, therefore, effectively increases radiative energy input to the Earth. But what happens to this radiative input is complex: It is redistributed, both vertically and horizontally, by various physical processes, including advection, convection, and diffusion in the atmosphere and ocean.
When an increase in CO2 increases the radiative input to the atmosphere, how and in which direction does the atmosphere respond? Hypotheses about this response differ and are schematically shown in figure 9. Without the greenhouse effect, the Earth would be about 14 ºC cooler (25). The radiative contribution of doubling atmospheric CO2 is minor, but this radiative greenhouse effect is treated quite differently by different climate hypotheses. The hypotheses that the IPCC has chosen to adopt predict that the effect of CO2 is amplified by the atmosphere (especially water vapor) to produce a large temperature increase (14). Other hypotheses, shown as hypothesis 2, predict the opposite that the atmospheric response will counteract the CO2 increase and result in insignificant changes in global temperature (25-27). The empirical evidence of figures 5-7 favors hypothesis 2. While CO2 has increased substantially, the large temperature increase predicted by the IPCC models has not occurred (see figure 11).
The hypothesis of a large atmospheric temperature increase from greenhouse gases (GHGs), and further hypotheses that temperature increases will lead to flooding, increases in storm activity, and catastrophic world-wide climatological changes have come to be known as ''global warming'' a phenomenon claimed to be so dangerous that it makes necessary a dramatic reduction in world energy use and a severe program of international rationing of technology (29).
•
Figure 10: The radiative greenhouse effect of doubling the concentration of atmospheric CO2 (right bar) as compared with four of the uncertainties in the computer climate models (14, 28).
The computer climate models upon which ''global warming'' is based have substantial uncertainties. This is not surprising, since the climate is a coupled, non-linear dynamical system in layman's terms, a very complex one. Figure 10 summarizes some of the difficulties by comparing the radiative CO2 greenhouse effect with correction factors and uncertainties in some of the parameters in the computer climate calculations. Other factors, too, such as the effects of volcanoes, cannot now be reliably computer modeled.
Figure 11 compares the trend in atmospheric temperatures predicted by computer models adopted by the IPCC with that actually observed during the past 19 years those years in which the highest atmospheric concentrations of CO2 and other GHGs have occurred.
In effect, an experiment has been performed on the Earth during the past half-century an experiment that includes all of the complex factors and feedback effects that determine the Earth's temperature and climate. Since 1940, atmospheric GHGs have risen substantially. Yet atmospheric temperatures have not risen. In fact, during the 19 years with the highest atmospheric levels of CO2 and other GHGs, temperatures have fallen.
•
Figure 11:
Global annual lower tropospheric temperatures as measured by satellite MSU between latitudes 83 N and 83 S (17, 18) plotted as deviations from the 1979 value. The trend line of these experimental measurements is compared with the corresponding trend line predicted by International Panel on Climate Change (IPCC) computer climate models (14).
Not only has the global warming hypothesis failed the experimental test; it is theoretically flawed as well. It can reasonably be argued that cooling from negative physical and biological feedbacks to GHGs will nullify the initial temperature rise (26, 30).
The reasons for this failure of the computer climate models are subjects of scientific debate. For example, water vapor is the largest contributor to the overall greenhouse effect (31). It has been suggested that the computer climate models treat feedbacks related to water vapor incorrectly (27, 32).
The global warming hypothesis is not based upon the radiative properties of the GHGs themselves. It is based entirely upon a small initial increase in temperature caused by GHGs and a large theoretical amplification of that temperature change. Any comparable temperature increase from another cause would produce the same outcome from the calculations.
At present, science does not have comprehensive quantitative knowledge about the Earth's atmosphere. Very few of the relevant parameters are known with enough rigor to permit reliable theoretical calculations. Each hypothesis must be judged by empirical results. The global warming hypothesis has been thoroughly evaluated. It does not agree with the data and is, therefore, not validated.
•
Figure 12: Eleven-year moving average of global surface temperature, as estimated by NASA GISS (23, 33, and 34), plotted as deviation from 1890 (left axis and light line), as compared with atmospheric CO2 (right axis and dark line) (2). Approximately 82% of the increase in CO2 occurred after the temperature maximum in 1940, as is shown in figure 1.
The new high in temperature estimated by NASA GISS after 1940 is not present in the radiosonde balloon measurements or the satellite MSU measurements. It is also not present in surface measurements for regions with comprehensive, high-quality temperature records (35). The United States surface temperature record (see figure 4) gives 1996 and 1997 as the 38th and 56th coolest years in the 20th century. Biases and uncertainties, such as that shown in figure 13, account for this difference.
Global Warming Evidence
Aside from computer calculations, two sorts of evidence have been advanced in support of the ''global warming'' hypothesis: temperature compilations and statements about global flooding and weather disruptions. Figure 12 shows the global temperature graph that has been compiled by National Aeronautic and Space Administration's Goddard Institute of Space Studies (NASA GISS) (23, 33, and 34). This compilation, which is shown widely in the press, does not agree with the atmospheric record because surface records have substantial uncertainties (36). Figure 13 illustrates part of the reason.
The urban heat island effect is only one of several surface effects that can confound compiled records of surface temperature. Figure 13 shows the size of this effect in, for example, the surface stations of California and the problems associated with objective sampling. The East Park station, considered the best situated rural station in the state (37), has a trend since 1940 of minus 0.055 ºC per decade.
•
Figure 13: Surface temperature trends for the period of 1940 to 1996 from 107 measuring stations in 49 California counties (39, 40). After averaging the means of the trends in each county, counties of similar population were bined and plotted as closed circles along with the standard errors of their means. The six measuring stations in Los Angeles County were used to calculate the standard error of that county, which is plotted alone at the county population of 8.9 million. The ''urban heat island effect'' on surface ments is evident. The straight line is a least-squares fit to the closed circles. The points marked ''X'' are the six unadjusted station records selected by NASA GISS (23, 33, and 34) for use in their estimate of global temperatures as shown in figure 12.
The overall rise of about plus 0.5 ºC during the 20th century is often cited in support of ''global warming'' (38). Since, however, 82% of the CO2 rise during the 20th century occurred after the rise in temperature (see figures 1 and 12), the CO2 increase cannot have caused the temperature increase. The 19th century rise was only 13 ppm (2).
In addition, incomplete regional temperature records have been used to support ''global warming.'' Figure 14 shows an example of this, in which a partial record was used in an attempt to confirm computer climate model predictions of temperature increases from green-house gases (41). A more complete record refuted this attempt (42).
Not one of the temperature graphs shown in figures 4 to 7, which include the most accurate and reliable surface and atmospheric temperature measurements available, both global and regional, shows any warming whatever that can be attributed to increases in green-house gases. Moreover, these data show that present day temperatures are not at all unusual compared with natural variability, nor are they changing in any unusual way.
•
Figure 14: The solid circles in the oval are tropospheric temperatures for the Southern Hemisphere between latitudes 30 S and 60 S, published in 1996 (41) in support of computer-model-projected warming. Later in 1996, the study was refuted by a longer set of data, as shown by the open circles (42).
Sea Levels And Storms
The computer climate models do not make any reliable predictions whatever concerning global flooding, storm variability, and other catastrophes that have come to be a part of the popular definition of ''global warming.'' (See Chapter 6, section 6-5 of reference 14.) Yet several scenarios of impending global catastrophe have arisen separately. One of these hypothesizes that rising sea levels will flood large areas of coastal land. Figure 15 shows satellite measurements of global sea level between 1993 and 1997 (43). The reported current global rate of rise amounts to only about plus 2 mm per year, or plus 8 inches per century, and even this estimate is probably high (43). The trends in rise and fall of sea level in various regions have a wide range of about 100 mm per year with most of the globe showing downward trends (43).
•
Figure 15: Global sea level measurements from the Topex/Poseidon satellite altimeter for 1993 to 1997 (43). The instrument record gives a rate of change of minus 0.2 mm per year (43). However, it has been reported that 50-year tide gauge measurements give plus 1.8 mm per year. A correction of plus 2.3 mm per year was added to the satellite data based on comparison to selected tide gauges to get a value of plus 2.1 mm per year or 8 inches per century (43).
Historical records show no acceleration in sea level rise in the 20th century (44). Moreover, claims that global warming will cause the Antarctic ice cap to melt and sharply increase this rate are not consistent with experiment or with theory (45).
Similarly, claims that hurricane frequencies and intensities have been increasing are also inconsistent with the data. Figure 16 shows the number of severe Atlantic hurricanes per year and also the maximum wind intensities of those hurricanes. Both of these values have been decreasing with time.
•
Figure 16: Annual numbers of violent hurricanes and maximum attained wind speeds during those hurricanes in the Atlantic Ocean (46). Slopes of the trend lines are minus 0.25 hurricanes per decade and minus 0.33 meters per second maximum attained wind speed per decade.
As temperatures recover from the Little Ice Age, the more extreme weather patterns that characterized that period may be trending slowly toward the milder conditions that prevailed during the Middle Ages, which enjoyed average temperatures about 1 ºC higher than those of today. Concomitant changes are also taking place, such as the receding of glaciers in Montana's Glacier National Park.
Fertilization Of Plants
How high will the carbon dioxide concentration of the atmosphere ultimately rise if mankind continues to use coal, oil, and natural gas? Since total current estimates of hydrocarbon reserves are approximately 2,000 times annual use (47), doubled human release could, over a thousand years, ultimately be 10,000 GT C or 25% of the amount now sequestered in the oceans. If 90% of this 10,000 GT C were absorbed by oceans and other reservoirs, atmospheric levels would approximately double, rising to about 600 parts per million. (This assumes that new technologies will not supplant the use of hydrocarbons during the next 1,000 years, a pessimistic estimate of technological advance.)
One reservoir that would moderate the increase is especially important. Plant life provides a large sink for CO2. Using current knowledge about the increased growth rates of plants and assuming a doubling of CO2 release as compared to current emissions, it has been estimated that atmospheric CO2 levels will rise by only about 300 ppm before leveling off (2). At that level, CO2 absorption by increased Earth biomass is able to absorb about 10 GT C per year.
•
Figure 17: Standard normal deviates of tree ring widths for (a) bristlecone pine, limber pine, and fox tail pine in the Great Basin of California, Nevada, and Arizona and (b) bristlecone pine in Colorado (48). The tree ring widths have been normalized so that their means are zero and deviations from the means are displayed in units of standard deviation.
As atmospheric CO2 increases, plant growth rates increase. Also, leaves lose less water as CO2 increases, so that plants are able to grow under drier conditions. Animal life, which depends upon plant life for food, increases proportionally.
Figures 17 to 22 show examples of experimentally measured increases in the growth of plants. These examples are representative of a very large research literature on this subject (49-55). Since plant response to CO2 fertilization is nearly linear with respect to CO2 concentration over a range of a few hundred ppm, as seen for example in figures 18 and 22, it is easy to normalize experimental measurements at different levels of CO2 enrichment. This has been done in figure 23 in order to illustrate some CO2 growth enhancements calculated for the atmospheric increase of about 80 ppm that has already taken place, and that expected from a projected total increase of 320 ppm.
As figure 17 shows, long-lived (1,000- to 2000-year-old) pine trees have shown a sharp increase in growth rate during the past half-century.
•
Figure 18: Young Eldarica pine trees were grown for 23 months under four CO2 concentrations and then cut down and weighed. Each point represents an individual tree (56). Weights of tree parts are as indicated.
Figure 18 summarizes the increased growth rates of young pine seedlings at four CO2 levels. Again, the response is remarkable, with an increase of 300 ppm more than tripling the rate of growth.
•
Figure 19: Inventories of standing hardwood and softwood timber in the United States compiled from Forest Statistics of the United States (58).
Figure 19 shows the 30% increase in the forests of the United States that has taken place since 1950. Much of this increase is likely due to the increase in atmospheric CO2 that has already occurred. In addition, it has been reported that Amazonian rain forests are increasing their vegetation by about 34,000 moles (900 pounds) of carbon per acre per year (57), or about two tons of biomass per acre per year.
•
Figure 20: Fig. 20. Relative trunk and limb volumes and fine root biomass of young sour orange trees; and trunk and limb volumes and numbers of oranges produced per mature sour orange tree per year at 400 ppm CO2 (light bars) and 700 ppm CO2 (dark bars) (59, 60). The 400 ppm values were normalized to 100. The trees were planted in 1987 as one-year-old seedlings. Young trunk and limb volumes and fine root biomass were measured in 1990. Mature trunk and limb volumes are averages for 1991 to 1996. Orange numbers are averages for 1993 to 1997.
Figure 20 shows the effect of CO2 fertilization on sour orange trees. During the early years of growth, the bark, limbs, and fine roots of sour orange trees growing in an atmosphere with 700 ppm of CO2 exhibited rates of growth more than 170% greater than those at 400 ppm. As the trees matured, this slowed to about 100%. Meanwhile, orange production was 127% higher for the 700 ppm trees.
•
Figure 21: Grain yields from wheat grown under well watered and poorly watered conditions in open field experiments (61, 62). Average CO2-induced increases for the two years were 10% for wet and 23% for dry conditions.
Trees respond to CO2 fertilization more strongly than do most other plants, but all plants respond to some extent. Figure 21 shows the response of wheat grown under wet conditions and when the wheat was stressed by lack of water. These were open-field experiments. Wheat was grown in the usual way, but the atmospheric CO2 concentrations of circular sections of the fields were increased by means of arrays of computer-controlled equipment that released CO2 into the air to hold the levels as specified.
While the results illustrated in figures 17-21 are remarkable, they are typical of those reported in a very large number of studies of the effect of CO2 concentration upon the growth rates of plants (49-55).
Figure 22 summarizes 279 similar experiments in which plants of various types were raised under CO2-enhanced conditions. Plants under stress from less-than-ideal conditions – a common occurrence in nature – respond more to CO2 fertilization. The selections of species shown in figure 22 were biased toward plants that respond less to CO2 fertilization than does the mixture actually covering the Earth, so figure 22 underestimates the effects of global CO2 enhancement.
Figure 23 summarizes the wheat, orange tree, and young pine tree enhancements shown in figures 21, 20, and 18 with two atmospheric CO2 increases – that which has occurred since 1800 and is believed to be the result of the Industrial Revolution and that which is projected for the next two centuries. The relative growth enhancement of trees by CO2 diminishes with age. Figure 23 shows young trees.
Clearly, the green revolution in agriculture has already benefited from CO2 fertilization; and benefits in the future will likely be spectacular. Animal life will increase proportionally as shown by studies of 51 terrestrial (63) and 22 aquatic ecosystems (64). Moreover, as shown by a study of 94 terrestrial ecosystems on all continents except Antarctica (65), species richness (biodiversity) is more positively correlated with productivity – the total quantity of plant life per acre – than with anything else.
Discussion
There are no experimental data to support the hypothesis that increases in carbon dioxide and other greenhouse gases are causing or can be expected to cause catastrophic changes in global temperatures or weather. To the contrary, during the 20 years with the highest carbon dioxide levels, atmospheric temperatures have decreased.
We also need not worry about environmental calamities, even if the current long-term natural warming trend continues. The Earth has been much warmer during the past 3,000 years without catastrophic effects. Warmer weather extends growing seasons and generally improves the habitability of colder regions. ''Global warming,'' an invalidated hypothesis, provides no reason to limit human production of CO2, CH4, N2O, HFCs, PFCs, and SF6 as has been proposed (29).
•
Figure 22: Summary data from 279 published experiments in which plants of all types were grown under paired stressed (open circles) and unstressed (closed circles) conditions (66). There were 208, 50, and 21 sets at 300, 600, and an average of about 1350 ppm CO2, respectively. The plant mixture in the 279 studies was slightly biased toward plant types that respond less to CO2 fertilization than does the actual global mixture and therefore underestimates the expected global response. CO2 enrichment also allows plants to grow in drier regions, further increasing the expected global response.
Human use of coal, oil, and natural gas has not measurably warmed the atmosphere, and the extrapolation of current trends shows that it will not significantly do so in the foreseeable future. It does, however, release CO2, which accelerates the growth rates of plants and also permits plants to grow in drier regions. Animal life, which depends upon plants, also flourishes.
As coal, oil, and natural gas are used to feed and lift from poverty vast numbers of people across the globe, more CO2 will be released into the atmosphere. This will help to maintain and improve the health, longevity, prosperity, and productivity of all people.
Human activities are believed to be responsible for the rise in CO2 level of the atmosphere. Mankind is moving the carbon in coal, oil, and natural gas from below ground to the atmosphere and surface, where it is available for conversion into living things. We are living in an increasingly lush environment of plants and animals as a result of the CO2 increase. Our children will enjoy an Earth with far more plant and animal life as that with which we now are blessed. This is a wonderful and unexpected gift from the Industrial Revolution.

Figure 23(b): Calculated growth rate enhancement of wheat, young orange and very young pine trees already taking place as a result of atmospheric enrichment by CO2 during the past two centuries (a) and expected to take place as a result of atmospheric enrichment by CO2 to a level of 600 ppm (b).
In this case, these values apply to pine trees during their first two years of growth and orange trees during their 4th through 10th years of growth. As is shown in figure 20, the effect of increased CO2 gradually diminishes with tree age, so these values should not be interpreted as applicable over the entire tree lifespans. There are no longer-running controlled CO2 tree experiments. Yet, even 2,000 year old trees still respond significantly as is shown in figure 17.
