Enclosed is the packet for the Tuesday, February 12, 2008, commission meeting at 4:00 p.tn.
January 2008 water and electric usage is well above last year of 7.68% and 11.92% respectively.
There are no graphs in the financials this month because the graphs will only show one point fur
2008 and would be difficult to interpret.
Three of the engines at the landfill are due for their five year major overhaul. In January these
engines were replaced with rebuilt engines. It took about a day to disconnect, remove, reinstall,
and connect each engine.
The construction of Well #9 is in the development stages and will hopefully be completed in the
next couple of weeks. The construction of the small water treatment building is scheduled to
start in late February.
Maintenance of Well #, 7 is complete and should be operational next week.
We received 59 applications for our part-time accountant position, with 9 very good candidates.
We are starting the interviewing process.
Enclosed are the following articles for your review:
1) Agreement from the City of Otsego concerning rebuilding our overhead electric line
along County Road #39.
2) 2007 population statistics for Sherburne County taken from Sherburne County's building
report. Elk River's population is projected to be 23,473.
3) Copy of the Connector from the January 23, 2008, edition of the Elk River Star News.
This article discusses our rate increases and CIP programs.
4) The January 4, 2008, issue of the- Kiplinger Letter addressing energy issues.
5) Article titled "Is Ethanol Tapping Too Much Water" from the January 28, 2008, issue of
the Star Tribune.
6) Article titled "Environmental Effects of Increased Atmospheric Carbon Dioxide" from
the Journal of American Physicians and Surgeons. The scientific community still has
differing opinions on climate change and carbon dioxide.

AGREEMENT BETWEEN THE CITY OF OTSEGO AND ELK RIVER
MUNICIPAL UTILITIES AS TO UNDERGROUNDING OF ELECTRICAL
UTILITIES ACROSS CSAH 39 IN THE CITY OF OTSEGO
THIS AGREEMENT entered into this _ day of January, 2008 between the City of
Otsego (hereinafter CITY) and Elk River Municipal Utilities (hereinafter UTILITY).
WHEREAS, the City of Otsego's Right of Way Ordinance requires underground
installation of utilities within the City; and
WHEREAS, the Ordinance also provides that the Director may waive or modify
requirements of the ordinance upon a showing of good cause; and
WHEREAS, the issue of a delay in under grounding electrical utilities was presented to
the Otsego City Council at their regularly scheduled meeting on January 14; and
WHEREAS, based upon the facts presented the Council determined that a reasonable
delay in under grounding was appropriate and motioned that the Director approve the
waiver subject to a written Agreement.
FINDINGS
The Council deemed that the delay in implementation of the ordinance requirements was
justified by the following;
1. Under grounding of the electrical utility would be more appropriate upon
widening of CSAH 39, if such work is undertaken within a reasonable time
period.
2. Under grounding the system as per ordinance requirements would not allow for
proper looping of the system at this time.
3. Under grounding would be more appropriately accomplished in the context of a
larger overall project.
ORDER AND AGREEMENT
Based upon the information provided and the Findings as set forth above the Council has
motioned that the Director delay implementation of the under grounding requirements of
the City Right of Way Ordinance, subject to the UTILITIES agreement to the following
conditions:
That the UTILITY'S facilities are under grounded in compliance with City
Ordinances and any other applicable rules and regulations in place at the time work is
actually commenced upon the earliest occurrence of either a substantial upgrade to
CSAH 39 or by January ly 2018.

Power supplier's growth
spurs electric rate increases
Our wholesale power sup-
plier-Great River Energy-
is the fastest growing util-
ity in the state, and building
facilities to serve that growth
is expensive.
Because of a 10.7 per-
cent increase in the cost of
power we buy from GRE, we
have to increase our retail
rates. We are passing along
only 7.2 percent increase
to our retail customers. The
new rates will show up on
February bills.
The reason for GRE's
wholesale rate increase is
the construction of new facil-
ities, especially power plants
to satisfy ever-increasing
electric needs. Recently-
built power plants fueled by
gas instead of coal are also
susceptible to the volatile
gas market.
Our monthly customer
charge, to .help cover our
fixed costs; remains at $7.50
for residential customers
and $16.00 for commercial-
industrial customers.

Water rates {
"~ Demand for water,' espe- w'
cialty heavy lawn .sprinkling
in the summer, is driving the
average 6.0 percent increase
in water rates. The aver-
age residential customer
uses 5,000 to 6,000 gallons
of water per month in the
winter. In the summer, the
average consumption has
increased to over 24,000 '
gallons per month.
The rate increase varies "
depending on customer
usage, with heavier users
paying higher percentage
increases.
The rate structure, charg-
ing ahigher rate for higher
usage, is part of our water
conservation ,.plan and is
strongly recommended by
the state of Minnesota.
Ground water„ `particularly
from the sole aquifer under-
lying EIk River, is a valuable
natural resource. This water
is neither free nor inexhaust-

® Who are the big winners in the recently adopted energy law?
:Suppliers of components for fuel-efficient cars. Automakers
will scramble to meet a 40% increase in average fuel efficiency by 2020.
They'll snap up diesel engines from BorgWarner, Denso and Delphi.
Turbochargers from BorgWarner, IHI Corp. and Honeywell's Garrett.
Batteries for hybrids from Johnson Controls and Panasonic. Hitachi, TRW
and others will see more orders for electronic and mechanical components.
Lighting manufacturers. New efficiency regulations for lighting
will effectively KO incandescent bulbs by the middle of the next decade.
Lighting firms such as Osram Sylvania and Philips can expect huge demand
for light emitting diodes, compact fluorescents and pinpoint halogens.
Among smaller firms likely to benefit: Element Labs, an LED expert.
Orion Energy Systems, a cutting-edge player in efficient fluorescents.
And in the longer term...R&D leaders in cellulosic ethanol
and other cutting-edge biofuels. The new federal alt-fuel mandate,
which will require blending some 21 billion gallons of cellulosic ethanol
in auto fuel by 2022, will be a boon to the likes of Abengoa Bioenergy
of St. Louis and Poet of Sioux Falls, S.D. Plus Novozymes and DuPont
will be busy selling the enzymes to break down cellulosic materials.
Ethanol industry suppliers will hurt in the short term, however.
Corn-based ethanol production is outstripping the pace at which blenders
can mix ethanol into fuel. Meanwhile, ethanol makers are being squeezed
by the sharp rise in corn prices. So times will be tough for a few years.
An expanded FMLA, Family and Medical Leave Act, is coming soon.
~ After the new rules are signed into law early this year,
employers will be required to provide up to 12 weeks' unpaid leave
to immediate family members of reservists or National Guard members
who are called to active duty. Workers caring for family members
wounded during military duty are entitled to 26 weeks' unpaid leave.
Workers' personal protective Qear will cost you as of Mav 15.
Occupational Safety and Health Admin. regs will force firms to pay for it
in manufacturing facilities, shipyards, marine terminals, longshoring
and construction. OSHA sees 21,000 fewer injuries per year as a result.
® Keep your eve on the independents in the New Hampshire primary.
They make up 44% of the state's eligible voters, and on Jan. 8,
they can participate in either the Republican or the Democratic contest.
They will help determine who wins the party nominations,
boosting either Democrat Barack Obama or Republican John McCain.
Independents will also provide clues to the Nov. elections.
If most of them vote in the. Democratic contest, as happened in Iowa,
it suggests they would also desert the GOP in the general election.
And that would mean an across-the-board Democratic win later this year.

Is ethanol
tapping too

~ As the industry expands, Minnesota's
groundwater supply is under greater pressure.
By TOM MEER5MAN • meersman~a startribune.com
With a flood of ethanol plants headed toward
Minnesota, there's growing concern about wheth-
er there will be enough groundwater to satisfy the
booming industry's thirst.
The issue was brought into focus last year in
Granite Falls, where an ethanol plant in its first year

The MPCA Citizens' Board wants more informa-
tion about total groundwater supplies in the state,
as well as whether current and future ethanol plants
could consume it faster than it can be replenished.
':The industry is consuming about 2 billion gal-

Ethanol's growth spurs water worries
~ ETHANOL FROM Al
1 That amount could quadru-
ple by 20ll if the state's ethanol
production more than doubles,
as expected.
"I would characterize it as
a concern about where we're
going to allocate groundwa-
ter over the next 10 years rel-
ative to what are the needs go-
ing to be in 20 or 30 years, and
whether we're doing a good job
in thinking ahead; 'said MPCA
Commissioner Brad Moore.
In many cases, there's con-
siderable uncertainty about
how much water is available
underground.
And even when ethanol
plant developers test aqui-
fers-the underlying layers of
porous rock and sand that store
water -the results can be mis-
leading. The Granite Falls plant
had been given a temporary
three-year groundwater per-
mit from the Minnesota De-
partment of Natural Resourc-
es, but had to switch to the riv-
er after little over a year.
The ethanol industry is de-
veloping new technology that
will reduce the amount of wa-
terneeded to produce ethanol,
said Matt Hartwig, spokesman
for the Renewable Fuels Asso-
ciation, anational trade group.
"Industry. is very aware of its
use of natural resources like
water and we're taking steps to
improve that;' he said.

ation permits from the Min-
nesota Department of Natu-

Environmental Effects of Increased Atmospheric Carbon Dioxide
ARTHUR B. ROBINSON, NOAH E. ROBINSON, AND WILLIE SOON
Oregon Institute of Science and Medicine, 2251 Dick George Road, Cave Junction, Oregon 97523 [arty@oism.org]
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 ef-
fects upon Earth's weather and climate. Increased carbon diox-
ide has, however, markedly increased plant growth. Predictions
of harmful climatic effects due to future increases in hydrocar-
bon use and minor greenhouse gases like C02 do not conform to
current experimental knowledge. The environmental effects of
rapid expansion of the nuclear and hydrocarbon energy indus-
tries 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 (COZ). They feared that COZ would
result in "human-caused global warming" -hypothetical severe in-
creases in Earth's temperatures, with disastrous environmental con-
sequences. 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 re-
cords were short and were centered on a period of changing interme-
diate temperature trends. Additional experimental data have now
been obtained, so better answers to the questions raised by the hy-
pothesis of "human-caused global warming" are now available.

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-yeaz period. The Little Ice Age and Medieval Cli-
mate Optimum were naturally occurring, extended intervals of climate de-
partures from the mean. A value of 0.25 °C, which is the change in Sazgasso
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 temper-
ature was only about 1 ° Centigrade below the 3,000-year average.

pal source of melt energy is solaz radiation. Variations in glacier mass and
length are primarily due to temperature and precipitation (5,6). This melting

lengthen and shorten in delayed correlation with cooling and warm-
ing trends. Shortening lags temperature by about 20 years, so the cur-
rent warming trend began in about 1800.
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 (H20); and by other phenomena
that are more poorly understood. While major greenhouse gas HZO
substantially warms the Earth, minor greenhouse gases such as COZ

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 atmo-
spheric 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 dur-
ing the Medieval Climate Optimum 1,000 years ago (11,12).
Surface temperatures in the United States during the past century
reflect this natural warming trend and its correlation with solar activ-
ity, asshown 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 recov-
ery 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.
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 esti-
mates that Earth's temperature would be reduced by 0.6 °C through
particulate blocking of the sun by 0.2% (18).
Solar activity and U.S. surface temperature are closely correlated,
as shown in Figure 5, but U.S. surface temperature and world hydro-
carbon use are not correlated, as shown in Figure 13.
The U.S. temperature trend is so slight that, were the temperature

During the current period of recovery from the Little Ice Age, the
U.S. climate has improved somewhat, with more rainfall, fewer tor-
nados, 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 shorten-
ing and sea level rise began a century before the 60-year 6-fold in-
crease in hydrocarbon use, and have not changed during that
increase. Hydrocarbon use could not have caused these trends.
During the past 50 years, atmospheric C02 has increased by
22%. Much of that C02 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 COZ fertilizes plants.
Higher C02 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.
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 theo-
retical evidence of such an amplification.
Predictions of catastrophic global warnvng are based on computer
climate modeling, a branch of science still in its infancy. The empiri-
cal evidence -actual measurements of Earth's temperature and cli-
mate -shows no man-made warnung trend. Indeed, during four of
the seven decades since 1940 when average COz levels steadily
increased, U.S. average temperatures were actually decreasing.

Figure 11: Global sea level measured by surface gauges between 1807 and
2002 (24) and by satellite between 1993 and 2006 (25). Satellite measure-
ments are shown in gray and agree with tide gauge measurements. The over-
all trend is an increase of 7 inches per century. Intermediate trends aze 9, 0,
12, 0, and 12 inches per century, respectively. This trend lags the tempera-
ture 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.
While C02 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 abun-
dant, low-cost energy. This civilization has already brought unprece-
dented prosperity to the people of the more developed nations.
Billions of people in the less developed nations are now lifting them-
selves from poverty by adopting this technology.
Hydrocazbons are essential sources of energy to sustain and ex-
tend prosperity. This is especially true of the developing nations,
where available capital and technology are insufficient to meet rap-
idly 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 ra-
tions 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 pros-
perity of those in the developed countries would be greatly reduced.
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 geo-
graphical distributions vary as they adapt to changing conditions.
The temperature of the Earth is continuing its process of
fluctuation in correlation with variations in natural phenomena. Man-
kind, meanwhile, is moving some of the carbon in coal, oil, and natu-
ral gas from below ground to the atmosphere and surface, where it is
available for conversion into living things. We are living in an in-
creasingly 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 de-
scended into this relatively cool period from a wane interval about
1,000 years ago known as the "Medieval Climate Optimum." This is
shown in Figure 1 for the Sazgasso Sea.
During the Medieval Climate Optimum, temperatures were warn
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 aver-
age 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 typi-
cal of most places. Temperature records vary widely with geograph-
ical 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 system-
atically different aspects of unique geographical regions and by in-
clusion of regions where temperature records are unreliable.
Three key features of the temperature record -the Medieval Cli-
mate Optimum, the Little Ice Age, and the Not-Unusual-Tempera-
ture 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.
Most geographical locations experienced both the Medieval Cli-
mate Optimum and the Little Ice Age -and most locations did not

Figure 13: Seven independent records - solaz activity (9); Northern Hemi-
sphere, (13), Arctic (28), global (10), and U.S. (10) annual surface air tem-
peratures; sea level (24,25); and glacier length (4) -all qualitatively confine
each other by exhibiting three intermediate trends -warmer, cooler, and
warner. Sea level and glacier length are shown minus 20 years, correcting
for their 20-yeaz lag of atmospheric temperature. Solaz 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 hydrocazbon use. Temperature rose between
1910 and 1940, while hydrocarbon use was almost unchanged. Temperature
then fell between 1940 and 1972, while hydrocazbon use rose by 330%.
Also, the 150 to 200-yeaz slopes of the sea level and glacier trends were un-
changed by the very lazge increase in hydrocarbon use after 1940.
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, ap-
proximately 1 °C or 2 °F cooler than in the Medieval Period (12).
World glacier length (4) and world sea level (24,25) measure-
ments provide records of the recent cycle of recovery. Warmer tem-
peratures 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 an-
nual 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 hydrocazbon use. A fiuther doubling of world hydrocar-
bon 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 °C per
century. Global and Northern Hemisphere surface temperature re-
cords shown in Figure 13 trend upward at 0.6 °C per century. These
records are, however, biased toward higher temperatures in several
ways. For example, they preferentially use data near populated azeas
(33), where heat island effects are prevalent, as illustrated in Figure
15. A trend of 0.5 °C per century is more representative (13-17).
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 interme-
diate temperature downtrend, which led in the 1970s to fears of an
impending new ice age. This decrease in temperature occurred dur-
ing aperiod in which hydrocarbon use increased 3-fold.
Seven independent records -solar irradiance; Arctic, Northern
Hemisphere, global, and U.S. annual average surface air tempera-
tures; sea level; and glacier length -all exhibit these three intermedi-
ate 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 similaz to that shown in Figure 14 for balloon
and satellite tropospheric measurements. This trend is more pro-
nounced in the Northern Hemisphere than in the Southern. Contrary
to the COZ warnung climate models, however, tropospheric tempera-
tures aze not rising faster than surface temperatures.
Figure 6 illustrates the magnitudes of these temperature changes
by comparing the 0.5 °C per century temperature change as the Earth
recovers from the Little Ice Age, the range of 50-year averaged At-
lantic ocean surface temperatures in the Sargasso Sea over the past
3,000 years, the range ofday-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 comprehen-
sive geographic coverage. Even the satellite measurements, however,
contain short and medium-teen fluctuations greater than the slight
warming trends calculated from them. The calculated trends vary sig-
nificantly 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
compazed 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 COZ do not correlate with the
observed temperatures. Solar activity correlates quite well. Correla-
tion does not prove causality, but non-correlation proves non-causal-
ity. 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 respon-
sible for substantial Earth temperature fluctuations, but they do show
that human hydrocarbon use is not among those phenomena.
The overall experimental record is self-consistent. The Earth has
been warning as it recovers from the Little Ice Age at an average
rate of about 0.5 °C per century. Fluctuations within this temperature
trend include periods of more rapid increase and also periods of tem-
perature decrease. These fluctuations correlate well with concomitant
fluctuations in the activity of the sun. Neither the trends nor the fluc-
tuations within the trends correlate with hydrocarbon use. Sea level
and glacier length reveal three intermediate uptrends and two down-
trends since 1800, as does solar activity. These trends are climatically
benign and result from natural processes.

ATMOSPHERIC CARBON DIOXIDE
The concentration of C02 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 car-
bon per year. Total human industrial COz production, primarily from
use of coal, oil, and natural gas and the production of cement, is cur-
rently 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 atmo-
spheric C02.Office air concentrations often exceed 1,000 ppm C02.
To put these figures in perspective, it is estimated that the atmo-
sphere contains 780 Gt C; the surface ocean contains 1,000 Gt C;
vegetation, soils, and detritus contain 2,000 Gt C; and the intermedi-
ate and deep oceans contain 38,000 Gt C, as C02 or C02 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 ex-
change between them, and the uncertainties of these estimated num-
bers that the sources of the recent rise in atmospheric C02 have not
been determined with certainty (58,59). Atmospheric concentrations
of C02 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 dur-
ing 650,000 years in which COz, methane (CHq), and temperature
increased and then decreased (63-65). Ice-core records contain sub-
stantial uncertainties (58), so these correlations are imprecise.
In all seven glacial and interglacial cycles, the reported changes in
C02 and CHq lagged the temperature changes and could not, there-
fore, have caused them (66). These fluctuations probably involved
temperature-caused changes in oceanic and terrestrial COZ and CH4
content. More recent C02 fluctuations also lag temperature (67,68).
In 1957, Revelle and Seuss (69) estimated that tempera-
ture-caused out-gassing of ocean C02 would increase atmospheric

interglacial periods (63-65); from calculations (69) and measurements (70)
of sea water out-gassing; and as measured during the 20th and 21st centuries

release of ocean CO2. The COZ rises did not cause the temperature rises.
In addition to the agreement between the out-gassing estimates and mea-
surements, this conclusion is also verified by the small temperature rise dur-
ing the 20th and 21st centuries. If the COZ versus temperature correlation
during the seven interglacials had been caused by COz greenhouse wamvn
then the temperature rise per COZ rise would have been as high during the
20th and 21st centuries as it was during the seven interglacial periods.

Figure 17: Atmospheric COZ wncenhations 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 COZ is produced annually by human respiration and often leads to con-
centrations exceeding 1,000 ppm in public buildings. Atmospheric COZ has
increased 22% since 1958 and about 30% since 1880.
C02 by about 7% per °C temperature rise. The reported change dur-
ing 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 COz increased 30% per 0.1 °C
temperature change (72), and world COz increased 30% per 0.5 °C.
In addition to ocean out-gassing, C02 from human use of hydrocar-
bons is a new source. Neither this new source nor the older natural
C02 sources are causing atmospheric temperature to change.
The hypothesis that the C02 rise during the interglacials caused
the temperature to rise requires an increase of about 6 °C per 30%
rise in COz as seen in the ice core record. If this hypothesis were cor-
rect, 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, pro-
vides empirical evidence that invalidates this hypothesis.
Carbon dioxide has a very short residence time in the atmosphere.
Beginning with the 7 to 10-year half-time of C02 in the atmosphere
estimated by Revelle and Seuss (69), there were 36 estimates of the
atmospheric COZ 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 evi-
dence to support computer model estimates (73) of a COz atmo-
spheric "lifetime" of 300 years or more.
Human production of 8 Gt C per year of COZ is negligible as
compared with the 40,000 Gt C residing in the oceans and biosphere.
At ultimate equilibrium, human-produced C02 will have an
insignificant effect on the amounts in the various reservoirs. The
rates of approach to equilibrium are, however, slow enough that hu-
man use creates a transient atmospheric increase.
In any case, the sources and amounts of C02 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. COZ is merely an intermediate in a hypothetical
mechanism by which this "human-caused global warming" is said to
take place. The amount of atmospheric C02 does have profound en-
vironmental effects on plant and animal populations (74) and diver-
sity, 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 dis-
cern, 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 temper-
ature 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 cur-
rent rate, they will reach those of the Medieval Climate Optimum
about 2 centuries from now. Historical reports of that period record
the growing of wane weather crops in localities too cold for that pur-
pose today, so it is to be expected that the area of more temperate cli-
mate will expand as it did then. This is aheady being observed, as
studies at higher altitudes have reported increases in amount and di-
versity 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 in-
crease 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 oc-
curred 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 CHq in the Earth's atmo-
sphere, through combined convective readjustments and the radiative
blanketing effect, essentially decrease the net escape of terrestrial
thermal infrared radiation. Increasing CO2, therefore, effectively in-
creases 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.
When an increase in COZ increases the radiative input to the at-
mosphere, 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 °C cooler (81). The radiative contribution of dou-
bling atmospheric COZ is minor, but this radiative greenhouse effect
is treated quite differently by different climate hypotheses. The hy-
potheses that the IPCC (82,83) has chosen to adopt predict that the
effect of C02 is amplified by the atmosphere, especially by water va-
por, to produce a large temperature increase. Other hypotheses,
shown as hypothesis 2, predict the opposite -that the atmospheric re-
sponse will counteract the COZ increase and result in insignificant
changes in global temperature (81,84,85,91,92). The experimental
evidence, as described above, favors hypothesis 2. While COZ has
increased substantially, its effect on temperature has been so slight
that it has not been experimentally detected.
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 COZ 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 contin-
ued their cycle of recovery from the Little Ice Age in close correla-
tion 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 COZ is not based
upon the radiative properties of COZ itself, which is a very weak
greenhouse gas. It is based upon a small initial increase in tempera-
ture caused by COZ and a large theoretical amplification of that tem-
perature increase, primarily through increased evaporation of H2O, a

strong greenhouse gas. Any comparable temperature increase from
another cause would produce the same calculated outcome.
Thus, the 3,000-year temperature record illustrated in Figure 1
also provides a test of the computer models. The historical tempera-
ture 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 catas-
trophes, 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 hu-
man-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 warnming" -often called the "global
warnvng" -hypothesis depends entirely upon computer model-gen-
erated scenazios 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-home diseases, extensive
species extinction, catastrophic flooding of Pacific islands, ocean
acidification, increased numbers and severities of hurricanes and tor-
nados, and increased human heat deaths from the 0.5 °C per century
temperature rise are not consistent with actual observations. The "hu-
man-caused global wamming" hypothesis and the computer calcula-
tions that support it are in error. They have no empirical support and
aze 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 warn for opti-
mum human life?
Fitst, it would be necessary to detemune what temperature hu-
mans 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 C02 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 com-
mercial 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 °C and 3 °C of cooling. Both methods use parti-
cles 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 nucleaz and hydro-
carbon energy production and technological advance. This would
help humanity adapt and might lead to new mitigation technology.
FERTILIZATION OF PLANTS BY COZ
How high will the CO2 concentration of the atmosphere ulti-
mately rise if mankind continues to increase the use of coal, oil, and
natural gas`? At ultimate equilibrium with the ocean and other reser-
voirs 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 im-
portant. Plant life provides a large sink for CO2. Using current
knowledge about the increased growth rates of plants and assuming
increased CO2 release as compazed to current emissions, it has been
estimated that atmospheric CO2 levels may rise to about 600 ppm be-
fore 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 al-
ready 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 de-
pends upon plant life for food, increases proportionally.
Figures 21 to 24 show examples of experimentally measured in-
creases in the growth of plants. These examples are representative of
a very large reseazch 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.
Since plant response to CO2 fertilization is nearly linear with re-
spect 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, espe-
cially 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

hancement (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 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 na-
ture -respond more to COz fertilization. The selections of species in
Figure 23 were biased toward plants that respond less to CO2 fertil-
ization than does the mixture actually covering the Earth, so Figure
23 underestimates the effects of global CO2 enhancement.
Clearly, the green revolution in agriculture has already benefitted
from CO2 fertilization, and benefits in the future will be even greater.

Atmospheric C02 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 fer-
tilized. Animals obtain their carbon from plants. Without atmo-
spheric COz, none of the life we see on Earth would exist.

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 im-
ported oil and gas - and an additional amount for military expenses
related to those imports.

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 ft 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 ob-
viously 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 po-
litical 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 en-
ergy, 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 disadvan-
tages 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 cre-
ated by U.S. government barriers to American fuel breeding and re-
processing. 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 re-
actor incident. By contrast, American dependence on automobiles re-
sults 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 re-
sources 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
~ is.sx coi
geographical location and underlying assumptions. Figure 26 shows
a recent British study, which is typical. At present, 43% of U.S. en-
ergy consumption is used for electricity production.
To be sure, future inventions in energy technology may alter the
relative economics of nucleaz, 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. Alter-
natively, "conservation," if practiced so extensively as to be an alter-
native to hydrocarbon and nuclear power, is merely a politically
correct word for "poverty."
The current untenable situation in which the United States is los-
ing $300 billion per year to pay for foreign oil and gas is not the re-
sult of failures of government energy production efforts. The U.S.
govemment does not produce energy. Energy is produced by private
industry. Why then has energy production thrived abroad while do-
mestic production has stagnated?
This stagnation has been caused by United States government tax-
ation, 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 infe-
rior 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 stimu-
late industrial development, wherein competition could then automat-
ically detemvne the best paths.
Nucleaz 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 hydrocaz-
bon fuels provide, however, many conveniences, and a national in-
frastructure to use them is already in place. Oil from shale or coal
liquefaction is less expensive than crude oil at cunent 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
nucleaz power plants are very low.
Figure 27 illustrates, as an example, one practical and environ-
mentally 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 (ggawatts) (125). If this were increased by
560 GWe, nuclear power could fill all current U.S. electricity re-
quirements and have 230 GWe left over for export as electricity or as
hydrocarbon fuels replaced or manufactured.
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. re-

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
yeaz, 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-nucleaz activists. These impedi-
ments should be legislatively repealed.
quirements. Moreover, if heat from additional nucleaz 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.
The Palo Verde nuclear power station near Phoenix, Arizona, was
originally intended to have 10 nucleaz reactors with a generating ca-
pacity of 1,243 megawatts each. As a result of public hysteria caused
by false information -very similar to the human-caused global
wamring hysteria being spread today, construction at Palo Verde was
stopped with only three operating reactors completed. This installa-
tion 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 azea of 4,000
acres is 6.25 square miles or 2.5 miles squaze. The power station it-
selfoccupies 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 con-
stmcted today would be even more reliable and efficient.
Assuming a construction cost of $2.3 billion per 1,200 MWe re-
actor (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. Con-
struction 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 facili-
ties, there would be vigorous competition for them.
In addition to these power plants, the U.S. should build fuel repro-
cessing capability, so that spent nuclear fuel can be reused. This
would lower fuel cost and eliminate the storage of high-level nucleaz
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 nucleaz 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 in-
stallation 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 hydrocazbons 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 infrastruc-
ture is, however, much higher for hydrogen than for oil and gas.
Technological advance reduces cost, but usually not abruptly. A pre-
scient 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 to-
day for an abrupt change from oil and gas to hydrogen. In distin-
guishing the practical from the futuristic, a free market in energy is
absolutely essential.
Surely these are better outcomes than are available through inter-
national rationing and taxation of energy as has been recently pro-
posed (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 en-
ergy 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 fiuther indus-
trial 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 lazgely
from the less technologically complicated hydrocarbon sources. It is
a moral imperative that this energy be available. Otherwise, the ef-
forts of these peoples will be in vain, and they will slip backwards
into lives of poverty, suffering, and eazly 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 COz 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 modem 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. In-
expensive 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 in-
creases in human hydrocarbon use or in atmospheric cazbon 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 COz, 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 ef-
fects. Warmer weather extends growing seasons and generally im-
proves 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 C02 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 en-
ergy, not less. The most practical, economical, and environmentally
sound methods available are hydrocazbon 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 C02 produced does, how-
ever, 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 C02 in the at-
mosphere. Mankind is moving the carbon in coal, oil, and natural gas
from below ground to the atmosphere, where it is available for con-
version into living things. We are living in an increasingly lush envi-
ronment of plants and animals as a result of this C02 increase. Our
children will therefore enjoy an Earth with far more plant and animal
life than that with which we now aze blessed.
