Please note the other disciplines which have contributed considerably to
this. And without whose contributions this alternative view would not be
possible. Meaning if climatologists are indeed not looking at the reords
provided to determine past CO2 and temprature levels I'd like to know where
the thier data comes from. Simply taking daily tempratures for 10 years and
attempting to discern trends that may vary enormously over ten or hundreds of
thousands of years is on the face of it absurd.

It is clear and established that CO2 levels and temprature can be determined
by studying living and dead plant and animal remains. These studies have been
done for some time and not originally as a contributing data item for MMGW
but as a standard line of research. To exclude there results as being
irrelevant when such results contradict the MMGW theory is intellectual
dishonesty.

Since a climatologist cannot by Trevor's standard know anything about biology
he is dependent on the biolgist to provide such data.

I would therefore suggest that Trevor's entire hypothesis, like MMGW is
demonstrably false.

Having looked through the material and pro MMGW material I would say this
more conforms with the body of scientific knowledge that I was reading pre
1975. The notion of temprature variations, effects of the sun etc seemed to
be fairly well understood.

The one major flaw in MMGW not addressed but which has come to light is that
the locations of many of the temprature sensors is highly suspect and in
areas where artificially high tempratures have been recorded, notably near
cities which are notorious heat sinks with thier metal, concrete, asphalt and
tremendous output of thermal energy as a consequence of daily life.

Remember - MMGW is the new religion of the Godless seeking meaning. Having
rejected any objective sense of morality they now to seek to fill the gaping
whole with whatever nonsense is large and complex enough to emulate a
religion.

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 and early 21st centuries have produced no
deleterious effects upon Earth's weather and climate. Increased carbon
dioxide has, however, markedly increased plant growth. Predictions of harmful
climatic effects due to future increases in hydrocarbon use and minor
greenhouse gases like CO2 do not conform to current experimental knowledge.
The environmental effects of rapid expansion of the nuclear and hydrocarbon
energy industries are discussed.

SUMMARY
Political leaders gathered in Kyoto, Japan, in December 1997 to consider a
world treaty restricting human production of "greenhouse gases," chiefly
carbon dioxide (CO2). They feared that CO2 would result in "human-caused
global warming" ? hypothetical severe increases in Earth's temperatures, with
disastrous environmental consequences. During the past 10 years, many
political efforts have been made to force worldwide agreement to the Kyoto
treaty.

When we reviewed this subject in 1998 (1,2), existing satellite records were
short and were centered on a period of changing intermediate temperature
trends. Additional experimental data have now been obtained, so better
answers to the questions raised by the hypothesis of "human-caused global
warming" are now available.



Figure 1: Surface temperatures in the Sargasso Sea, a 2 million square mile
region of the Atlantic Ocean, with time resolution of 50 to 100 years and
ending in 1975, as determined by isotope ratios of marine organism remains in
sediment at the bottom of the sea (3). 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. A value of 0.25 °C, which is the change in Sargasso
Sea temperature between 1975 and 2006, has been added to the 1975 data in
order to provide a 2006 temperature value.
The average temperature of the Earth has varied within a range of about 3°C
during the past 3,000 years. It is currently increasing as the Earth recovers
from a period that is known as the Little Ice Age, as shown in Figure 1.
George Washington and his army were at Valley Forge during the coldest era in
1,500 years, but even then the temperature was only about 1° Centigrade below
the 3,000-year average.



Figure 2: Average length of 169 glaciers from 1700 to 2000 (4). The principal
source of melt energy is solar radiation. Variations in glacier mass and
length are primarily due to temperature and precipitation (5,6). This melting
trend lags the temperature increase by about 20 years, so it predates the 6-
fold increase in hydrocarbon use (7) even more than shown in the figure.
Hydrocarbon use could not have caused this shortening trend.
The most recent part of this warming period is reflected by shortening of
world glaciers, as shown in Figure 2. Glaciers regularly lengthen and shorten
in delayed correlation with cooling and warming trends. Shortening lags
temperature by about 20 years, so the current warming trend began in about
1800.



Figure 3: Arctic surface air temperature compared with total solar irradiance
as measured by sunspot cycle amplitude, sunspot cycle length, solar
equatorial rotation rate, fraction of penumbral spots, and decay rate of the
11-year sunspot cycle (8,9). Solar irradiance correlates well with Arctic
temperature, while hydrocarbon use (7) does not correlate.
Atmospheric temperature is regulated by the sun, which fluctuates in activity
as shown in Figure 3; by the greenhouse effect, largely caused by atmospheric
water vapor (H2O); and by other phenomena that are more poorly understood.
While major greenhouse gas H2O substantially warms the Earth, minor
greenhouse gases such as CO2 have little effect, as shown in Figures 2 and 3.
The 6-fold increase in hydrocarbon use since 1940 has had no noticeable
effect on atmospheric temperature or on the trend in glacier length.

While Figure 1 is illustrative of most geographical locations, there is great
variability of temperature records with location and regional climate.
Comprehensive surveys of published temperature records confirm the principal
features of Figure 1, including the fact that the current Earth temperature
is approximately 1 °C lower than that during the Medieval Climate Optimum
1,000 years ago (11,12).



Figure 4: Annual mean surface temperatures in the contiguous United States
between 1880 and 2006 (10). The slope of the least-squares trend line for
this 127-year record is 0.5 ºC per century.
Surface temperatures in the United States during the past century reflect
this natural warming trend and its correlation with solar activity, as shown
in Figures 4 and 5. Compiled U.S. surface temperatures have increased about
0.5 °C per century, which is consistent with other historical values of 0.4
to 0.5 °C per century during the recovery from the Little Ice Age (13-17).
This temperature change is slight as compared with other natural variations,
as shown in Figure 6. Three intermediate trends are evident, including the
decreasing trend used to justify fears of "global cooling" in the 1970s.



Figure 5: U.S. surface temperature from Figure 4 as compared with total solar
irradiance (19) from Figure 3.
Between 1900 and 2000, on absolute scales of solar irradiance and degrees
Kelvin, solar activity increased 0.19%, while a 0.5 °C temperature change is
0.21%. This is in good agreement with estimates that Earth's temperature
would be reduced by 0.6 °C through particulate blocking of the sun by 0.2%
(18).



Figure 6: Comparison between the current U.S. temperature change per century,
the 3,000-year temperature range in Figure 1, seasonal and diurnal range in
Oregon, and seasonal and diurnal range throughout the Earth.
Solar activity and U.S. surface temperature are closely correlated, as shown
in Figure 5, but U.S. surface temperature and world hydrocarbon use are not
correlated, as shown in Figure 13.

The U.S. temperature trend is so slight that, were the temperature change
which has taken place during the 20th and 21st centuries to occur in an
ordinary room, most of the people in the room would be unaware of it.



Figure 7: Annual precipitation in the contiguous 48 United States between
1895 and 2006. U.S. National Climatic Data Center, U.S. Department of
Commerce 2006 Climate Review (20). The trend shows an increase in rainfall of
1.8 inches per century ? approximately 6% per century.
During the current period of recovery from the Little Ice Age, the U.S.
climate has improved somewhat, with more rainfall, fewer tornados, and no
increase in hurricane activity, as illustrated in Figures 7 to 10. Sea level
has trended upward for the past 150 years at a rate of 7 inches per century,
with 3 intermediate uptrends and 2 periods of no increase as shown in Figure
11. These features are confirmed by the glacier record as shown in Figure 12.
If this trend continues as did that prior to the Medieval Climate Optimum,
sea level would be expected to rise about 1 foot during the next 200 years.

As shown in Figures 2, 11, and 12, the trends in glacier shortening and sea
level rise began a century before the 60-year 6-fold increase in hydrocarbon
use, and have not changed during that increase. Hydrocarbon use could not
have caused these trends.



Figure 8: Annual number of strong-to-violent category F3 to F5 tornados
during the March-to-August tornado season in the U.S. between 1950 and 2006.
U.S. National Climatic Data Center, U.S. Department of Commerce 2006 Climate
Review (20). During this period, world hydrocarbon use increased 6-fold,
while violent tornado frequency decreased by 43%.
During the past 50 years, atmospheric CO2 has increased by 22%. Much of that
CO2 increase is attributable to the 6-fold increase in human use of
hydrocarbon energy. Figures 2, 3, 11, 12, and 13 show, however, that human
use of hydrocarbons has not caused the observed increases in temperature.

The increase in atmospheric carbon dioxide has, however, had a substantial
environmental effect. Atmospheric CO2 fertilizes plants. Higher CO2 enables
plants to grow faster and larger and to live in drier climates. Plants
provide food for animals, which are thereby also enhanced. The extent and
diversity of plant and animal life have both increased substantially during
the past half-century. Increased temperature has also mildly stimulated plant
growth.



Figure 9: Annual number of Atlantic hurricanes that made landfall between
1900 and 2006 (21). Line is drawn at mean value.
Does a catastrophic amplification of these trends with damaging
climatological consequences lie ahead? There are no experimental data that
suggest this. There is also no experimentally validated theoretical evidence
of such an amplification.

Predictions of catastrophic 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 and climate ? shows no man-made
warming trend. Indeed, during four of the seven decades since 1940 when
average CO2 levels steadily increased, U.S. average temperatures were
actually decreasing. While CO2 levels have increased substantially and are
expected to continue doing so and humans have been responsible for part of
this increase, the effect on the environment has been benign.

There is, however, one very dangerous possibility.

Our industrial and technological civilization depends upon abundant, low-cost
energy. This civilization has already brought unprecedented prosperity to the
people of the more developed nations. Billions of people in the less
developed nations are now lifting themselves from poverty by adopting this
technology.



Figure 10: Annual number of violent hurricanes and maximum attained wind
speed during those hurricanes in the Atlantic Ocean between 1944 and 2006
(22,23). There is no upward trend in either of these records. During this
period, world hydrocarbon use increased 6-fold. Lines are mean values.
Hydrocarbons are essential sources of energy to sustain and extend
prosperity. This is especially true of the developing nations, where
available capital and technology are insufficient to meet rapidly increasing
energy needs without extensive use of hydrocarbon fuels. If, through
misunderstanding of the underlying science and through misguided public fear
and hysteria, mankind significantly rations and restricts the use of
hydrocarbons, the worldwide increase in prosperity will stop. The result
would be vast human suffering and the loss of hundreds of millions of human
lives. Moreover, the prosperity of those in the developed countries would be
greatly reduced.



Figure 11: Global sea level measured by surface gauges between 1807 and 2002
(24) and by satellite between 1993 and 2006 (25). Satellite measurements are
shown in gray and agree with tide gauge measurements. The overall trend is an
increase of 7 inches per century. Intermediate trends are 9, 0, 12, 0, and 12
inches per century, respectively. This trend lags the temperature increase,
so it predates the increase in hydrocarbon use even more than is shown. It is
unaffected by the very large increase in hydrocarbon use.
Mild ordinary natural increases in the Earth's temperature have occurred
during the past two to three centuries. These have resulted in some
improvements in overall climate and also some changes in the landscape, such
as a reduction in glacier lengths and increased vegetation in colder areas.
Far greater changes have occurred during the time that all current species of
animals and plants have been on the Earth. The relative population sizes of
the species and their geographical distributions vary as they adapt to
changing conditions.



Figure 12: Glacier shortening (4) and sea level rise (24,25). Gray area
designates estimated range of error in the sea level record. These
measurements lag air temperature increases by about 20 years. So, the trends
began more than a century before increases in hydrocarbon use.
The temperature of the Earth is continuing its process of fluctuation in
correlation with variations in natural phenomena. Mankind, meanwhile, is
moving some of 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. This is an unexpected and wonderful gift from the
Industrial Revolution.

ATMOSPHERIC AND SURFACE TEMPERATURES
Atmospheric and surface temperatures have been recovering from an unusually
cold period. During the time between 200 and 500 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." This is shown in Figure 1 for the Sargasso Sea.

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 200 to 300 years, Earth temperatures
have been gradually recovering (26). Sargasso Sea temperatures are now
approximately equal to the average for the previous 3,000 years.

The historical record does not contain any report of "global warming"
catastrophes, even though temperatures have been higher than they are now
during much of the last three millennia.

The 3,000-year range of temperatures in the Sargasso Sea is typical of most
places. Temperature records vary widely with geographical location as a
result of climatological characteristics unique to those specific regions, so
an "average" Earth temperature is less meaningful than individual records
(27). So called "global" or "hemispheric" averages contain errors created by
averaging systematically different aspects of unique geographical regions and
by inclusion of regions where temperature records are unreliable.

Three key features of the temperature record ? the Medieval Climate Optimum,
the Little Ice Age, and the Not-Unusual-Temperature of the 20th century ?
have been verified by a review of local temperature and temperature-
correlated records throughout the world (11), as summarized in Table 1. Each
record was scored with respect to those queries to which it applied. The
experimental and historical literature definitively confirms the primary
features of Figure 1.



Table 1: Comprehensive review of all instances in which temperature or
temperature-correlated records from localities throughout the world permit
answers to queries concerning the existence of the Medieval Climate Optimum,
the Little Ice Age, and an unusually warm anomaly in the 20th century (11).
The compiled and tabulated answers confirm the three principal features of
the Sargasso Sea record shown in Figure 1. The probability that the answer to
the query in column 1 is "yes" is given in column 5.
Most geographical locations experienced both the Medieval Climate Optimum and
the Little Ice Age ? and most locations did not experience temperatures that
were unusually warm during the 20th century. A review of 23 quantitative
records has demonstrated that mean and median world temperatures in 2006
were, on average, approximately 1 °C or 2 °F cooler than in the Medieval
Period (12).



Figure 13: Seven independent records ? solar activity (9); Northern
Hemisphere, (13), Arctic (28), global (10), and U.S. (10) annual surface air
temperatures; sea level (24,25); and glacier length (4) ? all qualitatively
confirm each other by exhibiting three intermediate trends ? warmer, cooler,
and warmer. Sea level and glacier length are shown minus 20 years, correcting
for their 20-year lag of atmospheric temperature. Solar activity, Northern
Hemisphere temperature, and glacier lengths show a low in about 1800.
Hydrocarbon use (7) is uncorrelated with temperature. Temperature rose for a
century before significant hydrocarbon use. Temperature rose between 1910 and
1940, while hydrocarbon use was almost unchanged. Temperature then fell
between 1940 and 1972, while hydrocarbon use rose by 330%. Also, the 150 to
200-year slopes of the sea level and glacier trends were unchanged by the
very large increase in hydrocarbon use after 1940.

World glacier length (4) and world sea level (24,25) measurements provide
records of the recent cycle of recovery. Warmer temperatures diminish
glaciers and cause sea level to rise because of decreased ocean water density
and other factors.

These measurements show that the trend of 7 inches per century increase in
sea level and the shortening trend in average glacier length both began a
century before 1940, yet 84% of total human annual hydrocarbon use occurred
only after 1940. Moreover, neither of these trends has accelerated during the
period between 1940 and 2007, while hydrocarbon use increased 6-fold. Sea
level and glacier records are offset by about 20 years because of the delay
between temperature rise and glacier and sea level change.

If the natural trend in sea level increase continues for another two
centuries as did the temperature rise in the Sargasso Sea as the Earth
entered the Medieval Warm Period, sea level would be expected to rise about 1
foot between the years 2000 and 2200. Both the sea level and glacier trends ?
and the temperature trend that they reflect ? are unrelated to hydrocarbon
use. A further doubling of world hydrocarbon use would not change these
trends.

Figure 12 shows the close correlation between the sea level and glacier
records, which further validates both records and the duration and character
of the temperature change that gave rise to them.

Figure 4 shows the annual temperature in the United States during the past
127 years. This record has an upward trend of 0.5 ºC per century. Global and
Northern Hemisphere surface temperature records shown in Figure 13 trend
upward at 0.6 ºC per century. These records are, however, biased toward
higher temperatures in several ways. For example, they preferentially use
data near populated areas (33), where heat island effects are prevalent, as
illustrated in Figure 15. A trend of 0.5 ºC per century is more
representative (13-17).



Figure 14: Satellite microwave sounding unit (blue) measurements of
tropospheric temperatures in the Northern Hemisphere between 0 and 82.5 N,
Southern Hemisphere between 0 and 82.5 S, tropics between 20S and 20N, and
the globe between 82.5N and 82.5S between 1979 and 2007 (29), and radiosonde
balloon (red) measurements in the tropics (29). The balloon measurements
confirm the satellite technique (29-31). The warming anomaly in 1997-1998
(gray) was caused by El Niño, which, like the overall trends, is unrelated to
CO2 (32).
The U.S. temperature record has two intermediate uptrends of comparable
magnitude, one occurring before the 6-fold increase in hydrocarbon use and
one during it. Between these two is an intermediate temperature downtrend,
which led in the 1970s to fears of an impending new ice age. This decrease in
temperature occurred during a period in which hydrocarbon use increased 3-
fold.

Seven independent records ? solar irradiance; Arctic, Northern Hemisphere,
global, and U.S. annual average surface air temperatures; sea level; and
glacier length ? all exhibit these three intermediate trends, as shown in
Figure 13. These trends confirm one another. Solar irradiance correlates with
them. Hydrocarbon use does not.

The intermediate uptrend in temperature between 1980 and 2006 shown in Figure
13 is similar to that shown in Figure 14 for balloon and satellite
tropospheric measurements. This trend is more pronounced in the Northern
Hemisphere than in the Southern. Contrary to the CO2 warming climate models,
however, tropospheric temperatures are not rising faster than surface
temperatures.

Figure 6 illustrates the magnitudes of these temperature changes by comparing
the 0.5 ºC per century temperature change as the Earth recovers from the
Little Ice Age, the range of 50-year averaged Atlantic ocean surface
temperatures in the Sargasso Sea over the past 3,000 years, the range of day-
night and seasonal variation on average in Oregon, and the range of day-night
and seasonal variation over the whole Earth. The two-century-long temperature
change is small.

Tropospheric temperatures measured by satellite give comprehensive geographic
coverage. Even the satellite measurements, however, contain short and medium-
term fluctuations greater than the slight warming trends calculated from
them. The calculated trends vary significantly as a function of the most
recent fluctuations and the lengths of the data sets, which are short.

Figure 3 shows the latter part of the period of warming from the Little Ice
Age in greater detail by means of Arctic air temperature as compared with
solar irradiance, as does Figure 5 for U.S. surface temperature. There is a
close correlation between solar activity and temperature and none between
hydrocarbon use and temperature. Several other studies over a wide variety of
time intervals have found similar correlations between climate and solar
activity (15, 34-39). Figure 3 also illustrates the uncertainties introduced
by limited time records. If the Arctic air temperature data before 1920 were
not available, essentially no uptrend would be observed.

This observed variation in solar activity is typical of stars close in size
and age to the sun (40). The current warming trends on Mars (41), Jupiter
(42), Neptune (43,44), Neptune's moon Triton (45), and Pluto (46-48) may
result, in part, from similar relations to the sun and its activity ? like
those that are warming the Earth.

Hydrocarbon use and atmospheric CO2 do not correlate with the observed
temperatures. Solar activity correlates quite well. Correlation does not
prove causality, but non-correlation proves non-causality. Human hydrocarbon
use is not measurably warming the earth. Moreover, there is a robust
theoretical and empirical model for solar warming and cooling of the Earth
(8,19,49,50). The experimental data do not prove that solar activity is the
only phenomenon responsible for substantial Earth temperature fluctuations,
but they do show that human hydrocarbon use is not among those phenomena.



Figure 15: Surface temperature trends for 1940 to 1996 from 107 measuring
stations in 49 California counties (51,52). The trends were combined for
counties of similar population and plotted 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 at a population
of 8.9 million. The "urban heat island effect" on surface measurements 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 (53-55) for use in their estimate of global surface temperatures. Such
selections make NASA GISS temperatures too high.
The overall experimental record is self-consistent. The Earth has been
warming as it recovers from the Little Ice Age at an average rate of about
0.5 ºC per century. Fluctuations within this temperature trend include
periods of more rapid increase and also periods of temperature decrease.
These fluctuations correlate well with concomitant fluctuations in the
activity of the sun. Neither the trends nor the fluctuations within the
trends correlate with hydrocarbon use. Sea level and glacier length reveal
three intermediate uptrends and two downtrends since 1800, as does solar
activity. These trends are climatically benign and result from natural
processes.


-----------------------------------------------------------------------------

ATMOSPHERIC CARBON DIOXIDE
The concentration of CO2 in Earth's atmosphere has increased during the past
century, as shown in Figure 17. The magnitude of this atmospheric increase is
currently about 4 gigatons (Gt C) of carbon per year. Total human industrial
CO2 production, primarily from use of coal, oil, and natural gas and the
production of cement, is currently about 8 Gt C per year (7,56,57). Humans
also exhale about 0.6 Gt C per year, which has been sequestered by plants
from atmospheric CO2. Office air concentrations often exceed 1,000 ppm CO2.

To put these figures in perspective, it is estimated that the atmosphere
contains 780 Gt C; the surface ocean contains 1,000 Gt C; vegetation, soils,
and detritus contain 2,000 Gt C; and the intermediate and deep oceans contain
38,000 Gt C, as CO2 or CO2 hydration products. Each year, the surface ocean
and atmosphere exchange an estimated 90 Gt C; vegetation and the atmosphere,
100 Gt C; marine biota and the surface ocean, 50 Gt C; and the surface ocean
and the intermediate and deep oceans, 40 Gt C (56,57).

So great are the magnitudes of these reservoirs, the rates of exchange
between them, and the uncertainties of these estimated numbers that the
sources of the recent rise in atmospheric CO2 have not been determined with
certainty (58,59). 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 200 ppm (60-
62).

Ice-core records are reported to show seven extended periods during 650,000
years in which CO2, methane (CH4), and temperature increased and then
decreased (63-65). Ice-core records contain substantial uncertainties (58),
so these correlations are imprecise.

In all seven glacial and interglacial cycles, the reported changes in CO2 and
CH4 lagged the temperature changes and could not, therefore, have caused them
(66). These fluctuations probably involved temperature-caused changes in
oceanic and terrestrial CO2 and CH4 content. More recent CO2 fluctuations
also lag temperature (67,68).



Figure 16: Temperature rise versus CO2 rise from seven ice-core measured
interglacial periods (63-65); from calculations (69) and measurements (70) of
sea water out-gassing; and as measured during the 20th and 21st centuries
(10,72). The interglacial temperature increases caused the CO2 rises through
release of ocean CO2. The CO2 rises did not cause the temperature rises.
In addition to the agreement between the out-gassing estimates and
measurements, this conclusion is also verified by the small temperature rise
during the 20th and 21st centuries. If the CO2 versus temperature correlation
during the seven interglacials had been caused by CO2 greenhouse warming,
then the temperature rise per CO2 rise would have been as high during the
20th and 21st centuries as it was during the seven interglacial periods.

In 1957, Revelle and Seuss (69) estimated that temperature-caused out-gassing
of ocean CO2 would increase atmospheric CO2 by about 7% per °C temperature
rise. The reported change during the seven interglacials of the 650,000-year
ice core record is about 5% per °C (63), which agrees with the out-gassing
calculation.

Between 1900 and 2006, Antarctic CO2 increased 30% per 0.1 °C temperature
change (72), and world CO2 increased 30% per 0.5 °C. In addition to ocean
out-gassing, CO2 from human use of hydrocarbons is a new source. Neither this
new source nor the older natural CO2 sources are causing atmospheric
temperature to change.

The hypothesis that the CO2 rise during the interglacials caused the
temperature to rise requires an increase of about 6 °C per 30% rise in CO2 as
seen in the ice core record. If this hypothesis were correct, Earth
temperatures would have risen about 6 °C between 1900 and 2006, rather than
the rise of between 0.1 °C and 0.5 °C, which actually occurred. This
difference is illustrated in Figure 16.

The 650,000-year ice-core record does not, therefore, agree with the
hypothesis of "human-caused global warming," and, in fact, provides empirical
evidence that invalidates this hypothesis.



Figure 17: Atmospheric CO2 concentrations in parts per million by volume,
ppm, measured spectrophotometrically at Mauna Loa, Hawaii, between 1958 and
2007. These measurements agree well with those at other locations (71). Data
before 1958 are from ice cores and chemical analyses, which have substantial
experimental uncertainties. We have used 295 ppm for the period 1880 to 1890,
which is an average of the available estimates. About 0.6 Gt C of CO2 is
produced annually by human respiration and often leads to concentrations
exceeding 1,000 ppm in public buildings. Atmospheric CO2 has increased 22%
since 1958 and about 30% since 1880.
Carbon dioxide has a very short residence time in the atmosphere. Beginning
with the 7 to 10-year half-time of CO2 in the atmosphere estimated by Revelle
and Seuss (69), there were 36 estimates of the atmospheric CO2 half-time
based upon experimental measurements published between 1957 and 1992 (59).
These range between 2 and 25 years, with a mean of 7.5, a median of 7.6, and
an upper range average of about 10. Of the 36 values, 33 are 10 years or
less.

Many of these estimates are from the decrease in atmospheric carbon 14 after
cessation of atmospheric nuclear weapons testing, which provides a reliable
half-time. There is no experimental evidence to support computer model
estimates (73) of a CO2 atmospheric "lifetime" of 300 years or more.

Human production of 8 Gt C per year of CO2 is negligible as compared with the
40,000 Gt C residing in the oceans and biosphere. At ultimate equilibrium,
human-produced CO2 will have an insignificant effect on the amounts in the
various reservoirs. The rates of approach to equilibrium are, however, slow
enough that human use creates a transient atmospheric increase.

In any case, the sources and amounts of CO2 in the atmosphere are of
secondary importance to the hypothesis of "human-caused global warming." It
is human burning of coal, oil, and natural gas that is at issue. CO2 is
merely an intermediate in a hypothetical mechanism by which this "human-
caused global warming" is said to take place. The amount of atmospheric CO2
does have profound environmental effects on plant and animal populations (74)
and diversity, as is discussed below.

CLIMATE CHANGE
While the average temperature change taking place as the Earth recovers from
the Little Ice Age is so slight that it is difficult to discern, its
environmental effects are measurable. Glacier shortening and the 7 inches per
century rise in sea level are examples. There are additional climate changes
that are correlated with this rise in temperature and may be caused by it.

Greenland, for example, is beginning to turn green again, as it was 1,000
years ago during the Medieval Climate Optimum (11). Arctic sea ice is
decreasing somewhat (75), but Antarctic ice is not decreasing and may be
increasing, due to increased snow (76-79).

In the United States, rainfall is increasing at about 1.8 inches per century,
and the number of severe tornados is decreasing, as shown in Figures 7 and 8.
If world temperatures continue to rise at the current rate, they will reach
those of the Medieval Climate Optimum about 2 centuries from now. Historical
reports of that period record the growing of warm weather crops in localities
too cold for that purpose today, so it is to be expected that the area of
more temperate climate will expand as it did then. This is already being
observed, as studies at higher altitudes have reported increases in amount
and diversity of plant and animal life by more than 50% (12,80).

Atmospheric temperature is increasing more in the Northern Hemisphere than in
the Southern, with intermediate periods of increase and decrease in the
overall trends.

There has been no increase in frequency or severity of Atlantic hurricanes
during the period of 6-fold increase in hydrocarbon use, as is illustrated in
Figures 9 and 10. Numbers of violent hurricanes vary greatly from year to
year and are no greater now than they were 50 years ago. Similarly, maximum
wind speeds have not increased.

All of the observed climate changes are gradual, moderate, and entirely
within the bounds of ordinary natural changes that have occurred during the
benign period of the past few thousand years.

There is no indication whatever in the experimental data that an abrupt or
remarkable change in any of the ordinary natural climate variables is
beginning or will begin to take place.

GLOBAL WARMING HYPOTHESIS
The greenhouse effect amplifies solar warming of the earth. Greenhouse gases
such as H2O, CO2, and CH4 in the Earth's atmosphere, through combined
convective readjustments and the radiative blanketing effect, essentially
decrease the net escape of terrestrial thermal infrared radiation. Increasing
CO2, therefore, effectively increases radiative energy input to the Earth's
atmosphere. The path of 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.



Figure 18: Qualitative illustration of greenhouse warming. "Present GHE" is
the current greenhouse effect from all atmospheric phenomena. "Radiative
effect of CO2" is the added greenhouse radiative effect from doubling CO2
without consideration of other atmospheric components. "Hypothesis 1 IPCC" is
the hypothetical amplification effect assumed by IPCC. "Hypothesis 2" is the
hypothetical moderation effect.
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 18. Without the water-
vapor greenhouse effect, the Earth would be about 14 ºC cooler (81). 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 (82,83) has chosen to adopt predict
that the effect of CO2 is amplified by the atmosphere, especially by water
vapor, to produce a large temperature increase. 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 (81,84,85,91,92). The experimental evidence, as described above,
favors hypothesis 2. While CO2 has increased substantially, its effect on
temperature has been so slight that it has not been experimentally detected.



Figure 19: 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 (87,93).
The computer climate models upon which "human-caused global warming" is based
have substantial uncertainties and are markedly unreliable. This is not
surprising, since the climate is a coupled, non-linear dynamical system. It
is very complex. Figure 19 illustrates 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 chemical and climatic influence of volcanoes, cannot now be
reliably computer modeled.

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, hydrocarbon use has risen 6-fold. Yet, this rise has had no effect on
the temperature trends, which have continued their cycle of recovery from the
Little Ice Age in close correlation with increasing solar activity.

Not only has the global warming hypothesis failed experimental tests, it is
theoretically flawed as well. It can reasonably be argued that cooling from
negative physical and biological feedbacks to greenhouse gases nullifies the
slight initial temperature rise (84,86).

The reasons for this failure of the computer climate models are subjects of
scientific debate (87). For example, water vapor is the largest contributor
to the overall greenhouse effect (88). It has been suggested that the climate
models treat feedbacks from clouds, water vapor, and related hydrology
incorrectly (85,89-92).

The global warming hypothesis with respect to CO2 is not based upon the
radiative properties of CO2 itself, which is a very weak greenhouse gas. It
is based upon a small initial increase in temperature caused by CO2 and a
large theoretical amplification of that temperature increase, primarily
through increased evaporation of H2O, a strong greenhouse gas. Any comparable
temperature increase from another cause would produce the same calculated
outcome.



Figure 20: Global atmospheric methane concentration in parts per million
between 1982 and 2004 (94).
Thus, the 3,000-year temperature record illustrated in Figure 1 also provides
a test of the computer models. The historical temperature record shows that
the Earth has previously warmed far more than could be caused by CO2 itself.
Since these past warming cycles have not initiated water-vapor-mediated
atmospheric warming catastrophes, it is evident that weaker effects from CO2
cannot do so.

Methane is also a minor greenhouse gas. World CH4 levels are, as shown in
Figure 20, leveling off. In the U.S. in 2005, 42% of human-produced methane
was from hydrocarbon energy production, 28% from waste management, and 30%
from agriculture (95). The total amount of CH4 produced from these U.S.
sources decreased 7% between 1980 and 2005. Moreover, the record shows that,
even while methane was increasing, temperature trends were benign.

The "human-caused global warming" ? often called the "global warming" ?
hypothesis depends entirely upon computer model-generated scenarios of the
future. There are no empirical records that verify either these models or
their flawed predictions (96).

Claims (97) of an epidemic of insect-borne diseases, extensive species
extinction, catastrophic flooding of Pacific islands, ocean acidification,
increased numbers and severities of hurricanes and tornados, and increased
human heat deaths from the 0.5 °C per century temperature rise are not
consistent with actual observations. The "human-caused global warming"
hypothesis and the computer calculations that support it are in error. They
have no empirical support and are invalidated by numerous observations.



WORLD TEMPERATURE CONTROL
World temperature is controlled by natural phenomena. What steps could
mankind take if solar activity or other effects began to shift the Earth
toward temperatures too cold or too warm for optimum human life?

First, it would be necessary to determine what temperature humans feel is
optimum. It is unlikely that the chosen temperature would be exactly that
which we have today. Second, we would be fortunate if natural forces were to
make the Earth too warm rather than too cold because we can cool the Earth
with relative ease. We have no means by which to warm it. Attempting to warm
the Earth with addition of CO2 or to cool the Earth by restrictions of CO2
and hydrocarbon use would, however, be futile. Neither would work.

Inexpensively blocking the sun by means of particles in the upper atmosphere
would be effective. S.S. Penner, A.M. Schneider, and E. M. Kennedy have
proposed (98) that the exhaust systems of commercial airliners could be tuned
in such a way as to eject particulate sun-blocking material into the upper
atmosphere. Later, Edward Teller similarly suggested (18) that particles
could be injected into the atmosphere in order to reduce solar heating and
cool the Earth. Teller estimated a cost of between $500 million and $1
billion per year for between 1 ºC and 3 ºC of cooling. Both methods use
particles so small that they would be invisible from the Earth.

These methods would be effective and economical in blocking solar radiation
and reducing atmospheric and surface temperatures. There are other similar
proposals (99). World energy rationing, on the other hand, would not work.

The climate of the Earth is now benign. If temperatures become too warm, this
can easily be corrected. If they become too cold, we have no means of
response ? except to maximize nuclear and hydrocarbon energy production and
technological advance. This would help humanity adapt and might lead to new
mitigation technology.


-----------------------------------------------------------------------------

FERTILIZATION OF PLANTS BY CO2
How high will the CO2 concentration of the atmosphere ultimately rise if
mankind continues to increase the use of coal, oil, and natural gas? At
ultimate equilibrium with the ocean and other reservoirs there will probably
be very little increase. The current rise is a non-equilibrium result of the
rate of approach to equilibrium.

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 increased CO2 release as
compared to current emissions, it has been estimated that atmospheric CO2
levels may rise to about 600 ppm before leveling off. At that level, CO2
absorption by increased Earth biomass is able to absorb about 10 Gt C per
year (100). At present, this absorption is estimated to be about 3 Gt C per
year (57).

About 30% of this projected rise from 295 to 600 ppm has already taken place,
without causing unfavorable climate changes. Moreover, the radiative effects
of CO2 are logarithmic (101,102), so more than 40% of any climatic influences
have already occurred.

As atmospheric CO2 increases, plant growth rates increase. Also, leaves
transpire less and 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.



Figure 21: Standard deviation from the mean 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 (110).
Tree ring widths were averaged in 20-year segments and then normalized so
that the means of prior tree growth were zero. The deviations from the means
are shown in units of standard deviations of those means.
Figures 21 to 24 show examples of experimentally measured increases in the
growth of plants. These examples are representative of a very large research
literature on this subject (103-109). As Figure 21 shows, long-lived 1,000-
to 2,000-year-old pine trees have shown a sharp increase in growth during the
past half-century. Figure 22 shows the 40% increase in the forests of the
United States that has taken place since 1950. Much of this increase is 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 900 pounds of carbon per acre per year (113), or approximately 2
tons of biomass per acre per year. Trees respond to CO2 fertilization more
strongly than do most other plants, but all plants respond to some extent.



Figure 22: Inventories of standing hardwood and softwood timber in the United
States compiled in Forest Resources of the United States, 2002, U.S.
Department of Agriculture Forest Service (111,112). The linear trend cited in
1998 (1) with an increase of 30% has continued. The increase is now 40%. The
amount of U.S. timber is rising almost 1% per year.
Since plant response to CO2 fertilization is nearly linear with respect to
CO2 concentration over the range from 300 to 600 ppm, as seen in Figure 23,
experimental measurements at different levels of CO2 enrichment can be
extrapolated. This has been done in Figure 24 in order to illustrate CO2
growth enhancements calculated for the atmospheric increase of about 88 ppm
that has already taken place and those expected from a projected total
increase of 305 ppm.

Wheat growth is accelerated by increased atmospheric CO2, especially under
dry conditions. Figure 24 shows the response of wheat grown under wet
conditions versus that of wheat stressed by lack of water. The underlying
data is from open-field experiments. Wheat was grown in the usual way, but
the atmospheric CO2 concentrations of circular sections of the fields were
increased by arrays of computer-controlled equipment that released CO2 into
the air to hold the levels as specified (115,116). Orange and young pine tree
growth enhancement (117-119) with two atmospheric CO2 increases ? that which
has already occurred since 1885 and that projected for the next two centuries
? is also shown. The relative growth enhancement of trees by CO2 diminishes
with age. Figure 24 shows young trees.



Figure 23: Summary data from 279 published experiments in which plants of all
types were grown under paired stressed (open red circles) and unstressed
(closed blue circles) conditions (114). 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.
Therefore, the figure underestimates the expected global response. CO2
enrichment also allows plants to grow in drier regions, further increasing
the response.
Figure 23 summarizes 279 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 in Figure 23 were biased toward
plants that respond less to CO2 fertilization than does the mixture actually
covering the Earth, so Figure 23 underestimates the effects of global CO2
enhancement.



Figure 24: Calculated (1,2) growth rate enhancement of wheat, young orange
trees, and very young pine trees already taking place as a result of
atmospheric enrichment by CO2 from 1885 to 2007 (a), and expected as a result
of atmospheric enrichment by CO2 to a level of 600 ppm (b).
Clearly, the green revolution in agriculture has already benefitted from CO2
fertilization, and benefits in the future will be even greater. Animal life
is increasing proportionally, as shown by studies of 51 terrestrial (120) and
22 aquatic ecosystems (121). Moreover, as shown by a study of 94 terrestrial
ecosystems on all continents except Antarctica (122), species richness ?
biodiversity ? is more positively correlated with productivity ? the total
quantity of plant life per acre ? than with anything else.

Atmospheric CO2 is required for life by both plants and animals. It is the
sole source of carbon in all of the protein, carbohydrate, fat, and other
organic molecules of which living things are constructed.

Plants extract carbon from atmospheric CO2 and are thereby fertilized.
Animals obtain their carbon from plants. Without atmospheric CO2, none of the
life we see on Earth would exist.

Water, oxygen, and carbon dioxide are the three most important substances
that make life possible.

They are surely not environmental pollutants.


-----------------------------------------------------------------------------
---



ENVIRONMENT AND ENERGY
The single most important human component in the preservation of the Earth's
environment is energy. Industrial conversion of energy into forms that are
useful for human activities is the most important aspect of technology.
Abundant inexpensive energy is required for the prosperous maintenance of
human life and the continued advance of life-enriching technology. People who
are prosperous have the wealth required to protect and enhance their natural
environment.

Currently, the United States is a net importer of energy as shown in Figure
25. Americans spend about $300 billion per year for imported oil and gas ?
and an additional amount for military expenses related to those imports.



Figure 25: In 2006, the United States obtained 84.9% of its energy from
hydrocarbons, 8.2% from nuclear fuels, 2.9% from hydroelectric dams, 2.1%
from wood, 0.8% from biofuels, 0.4% from waste, 0.3% from geothermal, and
0.3% from wind and solar radiation. The U.S. uses 21 million barrels of oil
per day ? 27% from OPEC, 17% from Canada and Mexico, 16% from others, and 40%
produced in the U.S. (95). The cost of imported oil and gas at $60 per barrel
and $7 per 1,000 ft3 in 2007 is about $300 billion per year.
Political calls for a reduction of U.S. hydrocarbon use by 90% (123), thereby
eliminating 75% of America's energy supply, are obviously impractical. Nor
can this 75% of U.S. energy be replaced by alternative "green" sources.
Despite enormous tax subsidies over the past 30 years, green sources still
provide only 0.3% of U.S. energy.

Yet, the U.S. clearly cannot continue to be a large net importer of energy
without losing its economic and industrial strength and its political
independence. It should, instead, be a net exporter of energy.

There are three realistic technological paths to American energy independence
? increased use of hydrocarbon energy, nuclear energy, or both. There are no
climatological impediments to increased use of hydrocarbons, although local
environmental effects can and must be accommodated. Nuclear energy is, in
fact, less expensive and more environmentally benign than hydrocarbon energy,
but it too has been the victim of the politics of fear and claimed
disadvantages and dangers that are actually negligible.

For example, the "problem" of high-level "nuclear waste" has been given much
attention, but this problem has been politically created by U.S. government
barriers to American fuel breeding and reprocessing. Spent nuclear fuel can
be recycled into new nuclear fuel. It need not be stored in expensive
repositories.

Reactor accidents are also much publicized, but there has never been even one
human death associated with an American nuclear reactor incident. By
contrast, American dependence on automobiles results in more than 40,000
human deaths per year.

All forms of energy generation, including "green" methods, entail industrial
deaths in the mining, manufacture, and transport of resources they require.
Nuclear energy requires the smallest amount of such resources (124) and
therefore has the lowest risk of deaths.

Estimated relative costs of electrical energy production vary with
geographical location and underlying assumptions. Figure 26 shows a recent
British study, which is typical. At present, 43% of U.S. energy consumption
is used for electricity production.

To be sure, future inventions in energy technology may alter the relative
economics of nuclear, hydrocarbon, solar, wind, and other methods of energy
generation. These inventions cannot, however, be forced by political fiat,
nor can they be wished into existence. Alternatively, "conservation," if
practiced so extensively as to be an alternative to hydrocarbon and nuclear
power, is merely a politically correct word for "poverty."

The current untenable situation in which the United States is losing $300
billion per year to pay for foreign oil and gas is not the result of failures
of government energy production efforts. The U.S. government does not produce
energy. Energy is produced by private industry. Why then has energy
production thrived abroad while domestic production has stagnated?

This stagnation has been caused by United States government taxation,
regulation, and sponsorship of litigation, which has made the U.S. a very
unfavorable place to produce energy. In addition, the U.S. government has
spent vast sums of tax money subsidizing inferior energy technologies for
political purposes.

It is not necessary to discern in advance the best course to follow.
Legislative repeal of taxation, regulation, incentives to litigation, and
repeal of all subsidies of energy generation industries would stimulate
industrial development, wherein competition could then automatically
determine the best paths.

Nuclear power is safer, less expensive, and more environmentally benign than
hydrocarbon power, so it is probably the better choice for increased energy
production. Solid, liquid and gaseous hydrocarbon fuels provide, however,
many conveniences, and a national infrastructure to use them is already in
place. Oil from shale or coal liquefaction is less expensive than crude oil
at current prices, but its ongoing production costs are higher than those for
already developed oil fields. There is, therefore, an investment risk that
crude oil prices could drop so low that liquefaction plants could not
compete. Nuclear energy does not have this disadvantage, since the operating
costs of nuclear power plants are very low.

Figure 27 illustrates, as an example, one practical and environmentally sound
path to U.S. energy independence. At present 19% of U.S. electricity is
produced by 104 nuclear power reactors with an average generating output in
2006 of 870 megawatts per reactor, for a total of about 90 GWe (gigawatts)
(125). If this were increased by 560 GWe, nuclear power could fill all
current U.S. electricity requirements and have 230 GWe left over for export
as electricity or as hydrocarbon fuels replaced or manufactured.



Figure 26: Delivered cost per kilowatt hour of electrical energy in Great
Britain in 2006, without CO2 controls (126). These estimates include all
capital and operational expenses for a period of 50 years. Micro wind or
solar are units installed for individual homes.
Thus, rather than a $300 billion trade loss, the U.S. would have a $200
billion trade surplus ? and installed capacity for future U.S. requirements.
Moreover, if heat from additional nuclear reactors were used for coal
liquefaction and gasification, the U.S. would not even need to use its oil
resources. The U.S. has about 25% of the world's coal reserves. This heat
could also liquify biomass, trash, or other sources of hydrocarbons that
might eventually prove practical.



Figure 27: Construction of one Palo Verde installation with 10 reactors in
each of the 50 states. Energy trade deficit is reversed by $500 billion per
year, resulting in a $200 billion annual surplus. Currently, this solution is
not possible owing to misguided government policies, regulations, and
taxation and to legal maneuvers available to anti-nuclear activists. These
impediments should be legislatively repealed.
The Palo Verde nuclear power station near Phoenix, Arizona, was originally
intended to have 10 nuclear reactors with a generating capacity of 1,243
megawatts each. As a result of public hysteria caused by false information ?
very similar to the human-caused global warming hysteria being spread today,
construction at Palo Verde was stopped with only three operating reactors
completed. This installation is sited on 4,000 acres of land and is cooled by
waste water from the city of Phoenix, which is a few miles away. An area of
4,000 acres is 6.25 square miles or 2.5 miles square. The power station
itself occupies only a small part of this total area.

If just one station like Palo Verde were built in each of the 50 states and
each installation included 10 reactors as originally planned for Palo Verde,
these plants, operating at the current 90% of design capacity, would produce
560 GWe of electricity. Nuclear technology has advanced substantially since
Palo Verde was built, so plants constructed today would be even more reliable
and efficient.

Assuming a construction cost of $2.3 billion per 1,200 MWe reactor (127) and
15% economies of scale, the total cost of this entire project would be $1
trillion, or 4 months of the current U.S. federal budget. This is 8% of the
annual U.S. gross domestic product. Construction costs could be repaid in
just a few years by the capital now spent by the people of the United States
for foreign oil and by the change from U.S. import to export of energy.

The 50 nuclear installations might be sited on a population basis. If so,
California would have six, while Oregon and Idaho together would have one. In
view of the great economic value of these facilities, there would be vigorous
competition for them.

In addition to these power plants, the U.S. should build fuel reprocessing
capability, so that spent nuclear fuel can be reused. This would lower fuel
cost and eliminate the storage of high-level nuclear waste. Fuel for the
reactors can be assured for 1,000 years (128) by using both ordinary reactors
with high breeding ratios and specific breeder reactors, so that more fuel is
produced than consumed.

About 33% of the thermal energy in an ordinary nuclear reactor is converted
to electricity. Some new designs are as high as 48%. The heat from a 1,243
MWe reactor can produce 38,000 barrels of coal-derived oil per day (129).
With one additional Palo Verde installation in each state for oil production,
the yearly output would be at least 7 billion barrels per year with a value,
at $60 per barrel, of more than $400 billion per year. This is twice the oil
production of Saudi Arabia. Current proven coal reserves of the United States
are sufficient to sustain this production for 200 years (128). This liquified
coal exceeds the proven oil reserves of the entire world. The reactors could
produce gaseous hydrocarbons from coal, too.

The remaining heat from nuclear power plants could warm air or water for use
in indoor climate control and other purposes.

Nuclear reactors can also be used to produce hydrogen, instead of oil and gas
(130,131). The current cost of production and infrastructure is, however,
much higher for hydrogen than for oil and gas. Technological advance reduces
cost, but usually not abruptly. A prescient call in 1800 for the world to
change from wood to methane would have been impracticably ahead of its time,
as may be a call today for an abrupt change from oil and gas to hydrogen. In
distinguishing the practical from the futuristic, a free market in energy is
absolutely essential.

Surely these are better outcomes than are available through international
rationing and taxation of energy as has been recently proposed
(82,83,97,123). This nuclear energy example demonstrates that current
technology can produce abundant inexpensive energy if it is not politically
suppressed.

There need be no vast government program to achieve this goal. It could be
reached simply by legislatively removing all taxation, most regulation and
litigation, and all subsidies from all forms of energy production in the
U.S., thereby allowing the free market to build the most practical mixture of
methods of energy generation.

With abundant and inexpensive energy, American industry could be revitalized,
and the capital and energy required for further industrial and technological
advance could be assured. Also assured would be the continued and increased
prosperity of all Americans.

The people of the United States need more low-cost energy, not less. If this
energy is produced in the United States, it can not only become a very
valuable export, but it can also ensure that American industry remains
competitive in world markets and that hoped-for American prosperity continues
and grows.

In this hope, Americans are not alone. Across the globe, billions of people
in poorer nations are struggling to improve their lives. These people need
abundant low-cost energy, which is the currency of technological progress.

In newly developing countries, that energy must come largely from the less
technologically complicated hydrocarbon sources. It is a moral imperative
that this energy be available. Otherwise, the efforts of these peoples will
be in vain, and they will slip backwards into lives of poverty, suffering,
and early death.

Energy is the foundation of wealth. Inexpensive energy allows people to do
wonderful things. For example, there is concern that it may become difficult
to grow sufficient food on the available land. Crops grow more abundantly in
a warmer, higher CO2 environment, so this can mitigate future problems that
may arise (12).

Energy provides, however, an even better food insurance plan. Energy-
intensive hydroponic greenhouses are 2,000 times more productive per unit
land area than are modern American farming methods (132). Therefore, if
energy is abundant and inexpensive, there is no practical limit to world food
production.

Fresh water is also believed to be in short supply. With plentiful
inexpensive energy, sea water desalination can provide essentially unlimited
supplies of fresh water.

During the past 200 years, human ingenuity in the use of energy has produced
many technological miracles. These advances have markedly increased the
quality, quantity, and length of human life. Technologists of the 21st
century need abundant, inexpensive energy with which to continue this
advance.

Were this bright future to be prevented by world energy rationing, the result
would be tragic indeed. In addition to human loss, the Earth's environment
would be a major victim of such a mistake. Inexpensive energy is essential to
environmental health. Prosperous people have the wealth to spare for
environmental preservation and enhancement. Poor, impoverished people do not.

CONCLUSIONS
There are no experimental data to support the hypothesis that increases in
human hydrocarbon use or in atmospheric carbon dioxide and other greenhouse
gases are causing or can be expected to cause unfavorable changes in global
temperatures, weather, or landscape. There is no reason to limit human
production of CO2, CH4, and other minor greenhouse gases as has been proposed
(82,83,97,123).

We also need not worry about environmental calamities even if the current
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.

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.

The United States and other countries need to produce more energy, not less.
The most practical, economical, and environmentally sound methods available
are hydrocarbon and nuclear technologies.

Human use of coal, oil, and natural gas has not harmfully warmed the Earth,
and the extrapolation of current trends shows that it will not do so in the
foreseeable future. The CO2 produced does, however, accelerate the growth
rates of plants and also permits plants to grow in drier regions. Animal
life, which depends upon plants, also flourishes, and the diversity of plant
and animal life is increased.

Human activities are producing part of the rise in CO2 in the atmosphere.
Mankind is moving the carbon in coal, oil, and natural gas from below ground
to the atmosphere, 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 this CO2 increase. Our children will therefore enjoy an Earth with
far more plant and animal life than that with which we now are blessed.
