What Every Citizen Needs to Know About Global Warming |
Gosh, you mean Global Warming FACTS without any Knee-Jerk Alarmism?
http://downloads.heartland.org/19381.pdf
Alarm over the prospect of the Earth warming is not warranted by the agreed
science or economics of the issue. Global warming is happening and man is
responsible for at least some of it. Yet this does not mean that global
warming will cause enough damage to the Earth and humanity to require
drastic cuts in energy use, a policy that would have damaging consequences
of its own. Moreover, science cannot answer questions that are at heart
economic or political, such as whether the Kyoto Protocol is worthwhile.
The Science
Isn't there a scientific consensus that global warming is real and bad for
us?
1.. . There is no "scientific consensus" that global warming will cause
damaging climate change. Claims that there is such a consensus
mischaracterize the scientific research of bodies like the United Nations
Intergovernmental Panel on Climate Change (IPCC) and the U.S. National
Academy of Sciences (NAS).
What do scientists agree on?
1.. . Scientists do agree that: 1) global average temperature is about
0.6°Celsius-or just over 1° Fahrenheit-higher than it was a century ago; 2)
atmospheric levels of carbon dioxide (CO2) have risen by about 30 percent
over the past 200 years; and 3) carbon dioxide, like water vapor, is a
greenhouse gas whose increase is likely to warm the Earth's atmosphere.1
Doesn't this mean we should be worried?
1.. . As Richard Lindzen of MIT summarized it in The Wall Street Journal,2
"These claims are true. However, what the public fails to grasp is that the
claims neither constitute support for alarm nor establish man's
responsibility for the small amount of warming that has occurred. In fact,
those who make the most outlandish claims of alarm are actually
demonstrating skepticism of the very science they say supports them. It isn't
just that the alarmists are trumpeting model results that we know must be
wrong. It is that they are trumpeting catastrophes that couldn't happen even
if the models were right as justifying costly policies to try to prevent
global warming." [Emphasis in original]
2
What don't scientists know yet?
1.. . Scientists do not agree on whether: 1) we know enough to ascribe
past temperature changes to carbon dioxide levels; 2) we have enough data to
confidently predict future temperature levels; and 3) at what level
temperature change might be more damaging than beneficial to life on Earth.
Didn't the National Academy of Sciences say greenhouse gases cause global
warming?
1.. . The National Academy of Sciences reported in 2001 that, "Because of
the large and still uncertain level of natural variability inherent in the
climate record and the uncertainties in the time histories of the various
forcing agents.a causal linkage between the buildup of greenhouse gases in
the atmosphere and the observed climate changes during the 20th century
cannot be unequivocally established." It also noted that 20 years' worth of
data is not long enough to estimate long-term trends. 3
Hasn't the Earth warmed precipitously over the past 100 years?
1.. . The temperature rise of 0.6°C over the last century is at the bottom
end of what climate models suggest should have happened. This suggests that
either the climate is less sensitive to greenhouse gases than previously
thought or that some unknown factor is depressing the temperature.4
Don't climate models warn of alarming future warming?
1.. . Predictions of 6°C temperature rises over the next 100 years are at
the extreme end of the IPCC range, and are the result of faulty economic
modeling, not science (see economics section below).
What are the realistic current estimates of future warming?
1.. . Both James Hansen of NASA-the father of greenhouse theory-and
Richard Lindzen of MIT-the most renowned climatologist in the world-agree
that, even if nothing is done to restrict greenhouse gases, the world will
only see a global temperature increase of about 1°C in the next 50-100
years. Hansen and his colleagues "predict additional warming in the next 50
years of 0.5 ± 0.2°C, a warming rate of 0.1 ± 0.04°C per decade."5
What about satellite temperature measurements?
1.. . Evidence from satellite and weather balloon soundings suggests that
the atmosphere has warmed considerably less than greenhouse theory
suggests.6 These measurements, which cover the whole atmosphere and show
only a very slight warming, show a disparity with the surface temperature
measurements, which cover only a small fraction of the Earth but show
sustained warming.
Hasn't the disagreement between satellite and surface temperatures been
resolved?
1.. . No. There is still substantial disagreement between the mid-range of
the satellite measurements and the mid-range of the surface measurements.
This presents a problem for climate models.
Do other man-made factors besides greenhouse gases influence temperature?
1.. . New research suggests that the role of greenhouse gases in warming
has been overestimated, as factors like atmospheric soot,7 land use change,8
and solar variation9 all appear to have contributed significantly to recent
warming.
3
The Scare Stories
Is the world in danger of plunging into a new ice age, as in the 2004 movie
The Day After Tomorrow?
1.. . No. The scenario presented in The Day After Tomorrow is physically
impossible. While research does suggest that the Gulf Stream has switched on
and off in the past, causing temperature drops in Europe, oceanographers are
convinced that global warming does not present any such danger.10
Is the world in severe danger from sea level rise?
1.. . No. Research from Nils-Axel Mörner, professor of paleogeophysics and
geodynamics at Stockholm University, demonstrates that current sea levels
are within the range of sea level oscillation over the past 300 years, while
the satellite data show virtually no rise over the past decade.11 The IPCC
foresees sea-level rise of between 0.1 and 0.9 meters by 2100. The Earth
experienced a sea-level rise of 0.2 meters over the past century with no
noticeable ill effects.
Another study relevant to this controversy is Zwally et al. (2005),12 which
examined changes in ice mass "from elevation changes derived from 10.5 years
(Greenland) and 9 years (Antarctica) of satellite radar altimetry data from
the European Remote-sensing Satellites ERS-1 and -2." The researchers report
a net contribution of the three ice sheets to sea level of +0.05 ± 0.03
millimeters per year. CO2Science.Org puts this in perspective: "At the
current sea-level-equivalent ice-loss rate of 0.05 millimeters per year, it
would take a full millennium to raise global sea level by just 5 cm, and it
would take fully 20,000 years to raise it a single meter."
Weren't recent extreme weather events caused by global warming?
1.. . There is no provable link between weather events like Hurricane
Katrina and global warming. For example, research by German scientists has
demonstrated that the devastating floods in central Europe in 2002 were
perfectly normal events when compared against the historical record.13
Allegations that extreme weather has been more damaging recently do not take
into account the fact that mankind is now living and investing resources in
more dangerous areas. Moreover, the World Meteorological Organization has
acknowledged that increases in the recorded number of extreme weather events
may be due to better observation and reporting.14 A top expert from the IPCC
resigned in January 2005 in protest that IPCC science was being
misrepresented by claims that last year's hurricane season was exacerbated
by global warming. Most hurricane scientists agree that there is no way that
Hurricane Katrina can be blamed on global warming.
2.. . Recent published research casts extreme doubt on the influence of
warming on hurricanes. Philip Klotzbach15 of Colorado State University finds
that, "The data indicate a large increasing trend in tropical cyclone
intensity and longevity for the North Atlantic basin and a considerable
decreasing trend for the Northeast Pacific. All other basins showed small
trends, and there has been no significant change in global net tropical
cyclone activity. There has been a small increase in global Category 4-5
hurricanes from the period 1986-1995 to the period 1996-2005. Most of this
increase is likely due to improved observational technology. These findings
indicate that other important factors govern intensity and frequency of
tropical cyclones besides SSTs [sea surface temperatures]."
Aren't the snows of Kilimanjaro disappearing because of global warming?
4
1.. . That's not the verdict of scientists who study Mount Kilimanjaro
most closely. In "Modern Glacier Retreat on Kilimanjaro as Evidence of
Climate Change: Observations and Facts,"16 Kaser et al. "develop a new
concept for investigating the retreat of Kilimanjaro's glaciers, based on
the physical understanding of glacier-climate interactions." They say, "The
concept considers the peculiarities of the mountain and implies that
climatological processes other than air temperature control the ice
recession in a direct manner. A drastic drop in atmospheric moisture at the
end of the 19th century and the ensuing drier climatic conditions are likely
forcing glacier retreat on Kilimanjaro."
Won't global warming lead to the spread of malaria?
1.. . Climate is not a significant factor in the recent growth of
vector-borne diseases such as malaria. Most experts on this subject agree
that malaria is more closely correlated with other factors; deforestation,
migration of lowland people (higher immunities, yet they bring disease with
them), construction of roads and dams, and the proliferation of pools and
ditches are much more important in predicting future spread of these
diseases.17
Didn't the U.S. Department of Defense conclude global warming poses a
national security threat?
1.. . The Pentagon is not convinced that global warming represents a major
security threat to the United States. The "secret paper" that garnered much
publicity in Europe was a self-admitted speculative exercise that went
beyond the bounds of measured research and had been released to the press
long before the sensationalist stories surfaced in Europe. Nor did the paper
recommend "immediate action" beyond better climate modeling.18
Haven't recent climate models found that global warming will be much worse
than previously thought?
1.. . The news that Oxford University has found that temperatures may
increase by up to 11°C severely misrepresents the scientific findings.
According to the actual scientific paper,19 the frequency distribution of
the results suggests that the lower end of temperature rises, in the 2°C to
4°C range, is the most likely.
Haven't the National Academies of all the major industrial countries agreed
that global warming is a serious threat?
1.. . Claims have been made that the scientific consensus is represented
by a statement drafted by the Royal Society of London and signed by the
national scientific academies of the G8 countries plus those of India,
Brazil, and China. But such claims ignore the politicized nature of the
statement. The climate change committee of the Russian Academy of Sciences
later said that its president should not have signed the statement, while
the use to which it was put was condemned by the outgoing president of the
U.S. National Academy of Sciences, Bruce Alberts, who called the Royal
Society's presentation of the statement "quite misleading."20
Aren't polar bears drowning because of melting ice?
1.. . These claims are overblown. A leading Canadian polar bear biologist
wrote recently, "Climate change is having an effect on the west Hudson
population of polar bears, but really, there is no need to panic. Of the 13
populations of polar bears in Canada, 11 are stable or increasing in number.
They are not going extinct, or even appear to be affected at present."21
5
Isn't there a scientific consensus such that one researcher found no
disagreement about global warming in the literature?
1.. . The research by Naomi Orsekes published in the journal Science in
December 2004 was flawed. She studied about 1,000 scientific abstracts, but
admitted to a sympathetic journalist that she made a major mistake in her
search terms. In fact, she should have reviewed about 12,000 abstracts. Even
taking her sample, another researcher who tried to replicate her study came
to quite different conclusions.22 In addition, the most recent survey of
climate scientists by Dennis Bray and Hans von Storch, following the same
methodology as a published study from 1996, found that while there had been
a move towards acceptance of anthropogenic global warming, only 9.4 percent
of respondents "strongly agree" that climate change is mostly the result of
anthropogenic sources. A similar proportion "strongly disagree."
Furthermore, only 22.8 percent of respondents "strongly agree" that the IPCC
reports accurately reflect a consensus within climate science.23
There is scientific agreement that the world has warmed and that man is at
least partly responsible for the warming-though there is no consensus on the
precise extent of man's effect on the climate. There is ongoing scientific
debate over the parameters used by the computer models that project future
climatic conditions. We cannot be certain whether the world will warm
significantly and we do not know how damaging-if at all-even significant
warming will be.
The Economics
Why is economics important to the study of global warming?
1.. . Predictions of global warming catastrophe are based on models that
rely on economics as much as on science. If the science of greenhouse theory
is right, then we can only assess its consequences by estimating future
production of greenhouse gases from estimates of economic activity.
Is there anything wrong with the economics underlying warming projections?
1.. . The economic modeling by the U.N. Intergovernmental Panel on Climate
Change is seriously flawed (The Economist called it "dangerously
incompetent"), relying on economic forecasts that show much faster growth
rates for developing countries than is justified.24 The IPCC economic
scenarios show significantly greater economic growth globally than do other
recognized, comparable scenarios.
What will the Kyoto Protocol do to reduce warming?
1.. . The Kyoto Protocol, most observers agree, will have virtually no
effect on temperature increase, as it imposes no restrictions on greenhouse
gas emissions upon major developing nations like China and India. These
nations have publicly refused to accept any restrictions now or in the
future.25
Can't we reduce emissions without affecting the economy?
1.. . Greenhouse gas emissions derive from energy use which in turn
derives from economic growth. Therefore, nations that restrict emissions are
almost certain to reduce their rate of economic growth.
Isn't global warming all cost and no benefit?
6
1.. . No. Even substantial global warming is likely to be of benefit to
the United States. As eminent Yale Professor Robert Mendehlson testified
before the Senate in 2000,26 "Climate change is likely to result in small
net benefits for the United States over the next century. The primary sector
that will benefit is agriculture. The large gains in this sector will more
than compensate for damages expected in the coastal, energy, and water
sectors, unless warming is unexpectedly severe. Forestry is also expected to
enjoy small gains. Added together, the United States will likely enjoy small
benefits of between $14 and $23 billion a year and will only suffer damages
in the neighborhood of $13 billion if warming reaches 5°C over the next
century. Recent predictions of warming by 2100 suggest temperature increases
of between 1.5°C and 4°C, suggesting that impacts are likely to be
beneficial in the U.S."
Haven't economic models predicted no effect of reducing emissions on growth?
1.. . European models of the effect of greenhouse gas emission
restrictions (such as PRIMES) are sectoral models that look at the effects
on only one economic sector and therefore badly underestimate the negative
effects of emission restrictions throughout the economy. General equilibrium
models, which take into account the effects of emissions restrictions on
other economic sectors, show much greater negative economic effects than do
sectoral models.27
What do the better economic models say Kyoto will do?
1.. . Recent research from general equilibrium models suggests strongly
negative impacts on European economies from adopting Kyoto targets (or going
beyond the targets, as in the case of the United Kingdom). One model shows
the economic effects by 2010 of adopting Kyoto targets as follows (remember
that the Protocol achieves virtually nothing in reducing global
temperature):28
Germany -5.2% GDP -1,800,000 jobs
Spain -5.0% GDP -1,000,000 jobs
United Kingdom -4.5% GDP -1,000,000 jobs
Netherlands -3.8% GDP -240,000 jobs
Isn't Europe on track to meet its Kyoto targets?
1.. . Kyoto targets are unrealistic. Regardless of announced targets, 11
of the 15 pre-enlargement EU countries are on course to increase their
greenhouse gas emissions well beyond their individual Kyoto targets.29
Specific Economic Issues
Isn't President Bush to blame for holding up Kyoto?
1.. . It is not the case that President Bush has unilaterally held up
ratification of the Kyoto treaty. The United States Senate must ratify any
treaty signed by a President. In 1997, during Bill Clinton's presidency, the
Senate (including recent Democratic presidential candidate John Kerry) voted
95-0 not to accept any Kyoto-style treaty that would significantly harm the
U. S. economy and did not include participation by major developing
countries.30 The U.S. President has no power to impose Kyoto, or any other
treaty, on an unwilling Senate.31
Doesn't Russia's participation demonstrate the appeal of Kyoto?
7
1.. . Russia agreed to ratify the Kyoto Protocol only after being
pressured by the European Union, which held out the prospect of endorsing
Russia's entry into the World Trade Organization. Both the Russian Academy
of Sciences and several Duma committees reported that Kyoto has no
scientific substantiation and may harm Russia's economy.32
Isn't global warming a worse threat than terrorism?
1.. . The charge that global warming is worse than terrorism in terms of
damage to the world is hyperbole. The implausible and unsubstantiable claim
of many deaths each year-the figure is often put at 150,000-owing to global
warming ignores the fact that most of those alleged deaths are due to
diseases such as malaria, which have historically existed even in cold
climates and could easily be controlled if the environmental lobby dropped
its opposition to the use of DDT.33 Moreover, that number is itself dwarfed
by the number killed by poverty, which will be increased if the world
decides to suppress the use of energy.
Can't we replace fossil fuels cheaply and effectively with renewable energy?
1.. . Alternative sources of energy such as wind and solar are not yet
cost-effective and come with environmental costs of their own (the veteran
British environmentalist David Bellamy is leading opposition to wind
farms).34 The only currently cost-effective alternative to fossil fuel use
is nuclear power, which produces nearly no emissions, but which
environmental activists continue to oppose in direct contradiction to their
assertions that global warming is the gravest danger the planet faces.
Aren't market-based solutions the way to reduce emissions?
1.. . "Cap and Trade" schemes that allow firms and governments to trade
the right to emit greenhouse gases up to certain limits are not economically
efficient. By creating rent-seeking opportunities, they promote the
development of a carbon cartel seeking to exploit the system to make
profits. The recent collapse of the carbon market in Europe shows how
dependent such markets are on political considerations. A simple carbon tax
would be much more economically efficient, although likely to prove
unattractive to voters in democracies.35
Summary
The world faces severe economic consequences from currently proposed
strategies to deal with global warming. These approaches will produce job
losses and consume scarce resources that could be better spent on handling
other global problems such as AIDS or lack of access to clean drinking
water.36 The economic consequences of global warming mitigation strategies
currently proposed will probably be worse than the effects of global warming
itself. Therefore, adaptation and resiliency strategies should be considered
as a more cost-effective alternative. In addition, "no regrets" strategies
that will provide benefits from greater economic

past temperature changes to carbon dioxide levels; 2) we have enough data
to confidently predict future temperature levels; and 3) at what level
temperature change might be more damaging than beneficial to life on
Earth.
Didn't the National Academy of Sciences say greenhouse gases cause global

Is the world in danger of plunging into a new ice age, as in the 2004

1.. . No. The scenario presented in The Day After Tomorrow is physically
impossible. While research does suggest that the Gulf Stream has switched
on and off in the past, causing temperature drops in Europe,
oceanographers are convinced that global warming does not present any such
danger.10
Is the world in severe danger from sea level rise?
1.. . No. Research from Nils-Axel Mörner, professor of paleogeophysics
and geodynamics at Stockholm University, demonstrates that current sea
levels are within the range of sea level oscillation over the past 300
years, while the satellite data show virtually no rise over the past
decade.11 The IPCC foresees sea-level rise of between 0.1 and 0.9 meters
by 2100. The Earth experienced a sea-level rise of 0.2 meters over the
past century with no noticeable ill effects.
Another study relevant to this controversy is Zwally et al. (2005),12
which examined changes in ice mass "from elevation changes derived from
10.5 years (Greenland) and 9 years (Antarctica) of satellite radar
altimetry data from the European Remote-sensing Satellites ERS-1 and -2."
The researchers report a net contribution of the three ice sheets to sea
level of +0.05 ± 0.03 millimeters per year. CO2Science.Org puts this in
perspective: "At the current sea-level-equivalent ice-loss rate of 0.05
millimeters per year, it would take a full millennium to raise global sea
level by just 5 cm, and it would take fully 20,000 years to raise it a
single meter."
Weren't recent extreme weather events caused by global warming?
1.. . There is no provable link between weather events like Hurricane
Katrina and global warming. For example, research by German scientists has
demonstrated that the devastating floods in central Europe in 2002 were
perfectly normal events when compared against the historical record.13
Allegations that extreme weather has been more damaging recently do not
take into account the fact that mankind is now living and investing
resources in more dangerous areas. Moreover, the World Meteorological
Organization has acknowledged that increases in the recorded number of
extreme weather events may be due to better observation and reporting.14 A
top expert from the IPCC resigned in January 2005 in protest that IPCC
science was being misrepresented by claims that last year's hurricane
season was exacerbated by global warming. Most hurricane scientists agree
that there is no way that Hurricane Katrina can be blamed on global
warming.
2.. . Recent published research casts extreme doubt on the influence of
warming on hurricanes. Philip Klotzbach15 of Colorado State University
finds that, "The data indicate a large increasing trend in tropical
cyclone intensity and longevity for the North Atlantic basin and a
considerable decreasing trend for the Northeast Pacific. All other basins
showed small trends, and there has been no significant change in global
net tropical cyclone activity. There has been a small increase in global
Category 4-5 hurricanes from the period 1986-1995 to the period 1996-2005.
Most of this increase is likely due to improved observational technology.
These findings indicate that other important factors govern intensity and
frequency of tropical cyclones besides SSTs [sea surface temperatures]."
Aren't the snows of Kilimanjaro disappearing because of global warming?
4
1.. . That's not the verdict of scientists who study Mount Kilimanjaro
most closely. In "Modern Glacier Retreat on Kilimanjaro as Evidence of
Climate Change: Observations and Facts,"16 Kaser et al. "develop a new
concept for investigating the retreat of Kilimanjaro's glaciers, based on
the physical understanding of glacier-climate interactions." They say,
"The concept considers the peculiarities of the mountain and implies that
climatological processes other than air temperature control the ice
recession in a direct manner. A drastic drop in atmospheric moisture at
the end of the 19th century and the ensuing drier climatic conditions are
likely forcing glacier retreat on Kilimanjaro."
Won't global warming lead to the spread of malaria?
1.. . Climate is not a significant factor in the recent growth of
vector-borne diseases such as malaria. Most experts on this subject agree
that malaria is more closely correlated with other factors; deforestation,
migration of lowland people (higher immunities, yet they bring disease
with them), construction of roads and dams, and the proliferation of pools
and ditches are much more important in predicting future spread of these
diseases.17

that went beyond the bounds of measured research and had been released to
the press long before the sensationalist stories surfaced in Europe. Nor
did the paper recommend "immediate action" beyond better climate
modeling.18
Haven't recent climate models found that global warming will be much worse
than previously thought?
1.. . The news that Oxford University has found that temperatures may
increase by up to 11°C severely misrepresents the scientific findings.
According to the actual scientific paper,19 the frequency distribution of
the results suggests that the lower end of temperature rises, in the 2°C
to 4°C range, is the most likely.
Haven't the National Academies of all the major industrial countries
agreed that global warming is a serious threat?
1.. . Claims have been made that the scientific consensus is represented
by a statement drafted by the Royal Society of London and signed by the
national scientific academies of the G8 countries plus those of India,
Brazil, and China. But such claims ignore the politicized nature of the
statement. The climate change committee of the Russian Academy of Sciences

wrote recently, "Climate change is having an effect on the west Hudson
population of polar bears, but really, there is no need to panic. Of the
13 populations of polar bears in Canada, 11 are stable or increasing in

Storch, following the same methodology as a published study from 1996,
found that while there had been a move towards acceptance of anthropogenic
global warming, only 9.4 percent of respondents "strongly agree" that
climate change is mostly the result of anthropogenic sources. A similar
proportion "strongly disagree." Furthermore, only 22.8 percent of
respondents "strongly agree" that the IPCC reports accurately reflect a
consensus within climate science.23
There is scientific agreement that the world has warmed and that man is at
least partly responsible for the warming-though there is no consensus on
the precise extent of man's effect on the climate. There is ongoing
scientific debate over the parameters used by the computer models that
project future climatic conditions. We cannot be certain whether the world
will warm significantly and we do not know how damaging-if at all-even
significant warming will be.
The Economics
Why is economics important to the study of global warming?
1.. . Predictions of global warming catastrophe are based on models that
rely on economics as much as on science. If the science of greenhouse
theory is right, then we can only assess its consequences by estimating
future production of greenhouse gases from estimates of economic activity.
Is there anything wrong with the economics underlying warming projections?
1.. . The economic modeling by the U.N. Intergovernmental Panel on
Climate Change is seriously flawed (The Economist called it "dangerously
incompetent"), relying on economic forecasts that show much faster growth
rates for developing countries than is justified.24 The IPCC economic
scenarios show significantly greater economic growth globally than do
other recognized, comparable scenarios.
What will the Kyoto Protocol do to reduce warming?
1.. . The Kyoto Protocol, most observers agree, will have virtually no
effect on temperature increase, as it imposes no restrictions on
greenhouse gas emissions upon major developing nations like China and
India. These nations have publicly refused to accept any restrictions now
or in the future.25
Can't we reduce emissions without affecting the economy?
1.. . Greenhouse gas emissions derive from energy use which in turn
derives from economic growth. Therefore, nations that restrict emissions
are almost certain to reduce their rate of economic growth.
Isn't global warming all cost and no benefit?
6
1.. . No. Even substantial global warming is likely to be of benefit to
the United States. As eminent Yale Professor Robert Mendehlson testified
before the Senate in 2000,26 "Climate change is likely to result in small
net benefits for the United States over the next century. The primary
sector that will benefit is agriculture. The large gains in this sector
will more than compensate for damages expected in the coastal, energy, and
water sectors, unless warming is unexpectedly severe. Forestry is also
expected to enjoy small gains. Added together, the United States will
likely enjoy small benefits of between $14 and $23 billion a year and will
only suffer damages in the neighborhood of $13 billion if warming reaches
5°C over the next century. Recent predictions of warming by 2100 suggest
temperature increases of between 1.5°C and 4°C, suggesting that impacts
are likely to be beneficial in the U.S."
Haven't economic models predicted no effect of reducing emissions on
growth?
1.. . European models of the effect of greenhouse gas emission
restrictions (such as PRIMES) are sectoral models that look at the effects
on only one economic sector and therefore badly underestimate the negative
effects of emission restrictions throughout the economy. General
equilibrium models, which take into account the effects of emissions
restrictions on other economic sectors, show much greater negative
economic effects than do sectoral models.27
What do the better economic models say Kyoto will do?
1.. . Recent research from general equilibrium models suggests strongly
negative impacts on European economies from adopting Kyoto targets (or
going beyond the targets, as in the case of the United Kingdom). One model
shows the economic effects by 2010 of adopting Kyoto targets as follows
(remember that the Protocol achieves virtually nothing in reducing global
temperature):28
Germany -5.2% GDP -1,800,000 jobs
Spain -5.0% GDP -1,000,000 jobs
United Kingdom -4.5% GDP -1,000,000 jobs
Netherlands -3.8% GDP -240,000 jobs
Isn't Europe on track to meet its Kyoto targets?
1.. . Kyoto targets are unrealistic. Regardless of announced targets, 11
of the 15 pre-enlargement EU countries are on course to increase their
greenhouse gas emissions well beyond their individual Kyoto targets.29
Specific Economic Issues
Isn't President Bush to blame for holding up Kyoto?
1.. . It is not the case that President Bush has unilaterally held up
ratification of the Kyoto treaty. The United States Senate must ratify any
treaty signed by a President. In 1997, during Bill Clinton's presidency,
the Senate (including recent Democratic presidential candidate John Kerry)
voted 95-0 not to accept any Kyoto-style treaty that would significantly
harm the U. S. economy and did not include participation by major
developing countries.30 The U.S. President has no power to impose Kyoto,
or any other treaty, on an unwilling Senate.31
Doesn't Russia's participation demonstrate the appeal of Kyoto?
7
1.. . Russia agreed to ratify the Kyoto Protocol only after being
pressured by the European Union, which held out the prospect of endorsing
Russia's entry into the World Trade Organization. Both the Russian Academy
of Sciences and several Duma committees reported that Kyoto has no
scientific substantiation and may harm Russia's economy.32
Isn't global warming a worse threat than terrorism?
1.. . The charge that global warming is worse than terrorism in terms of
damage to the world is hyperbole. The implausible and unsubstantiable
claim of many deaths each year-the figure is often put at 150,000-owing to
global warming ignores the fact that most of those alleged deaths are due
to diseases such as malaria, which have historically existed even in cold
climates and could easily be controlled if the environmental lobby dropped
its opposition to the use of DDT.33 Moreover, that number is itself
dwarfed by the number killed by poverty, which will be increased if the
world decides to suppress the use of energy.
Can't we replace fossil fuels cheaply and effectively with renewable
energy?
1.. . Alternative sources of energy such as wind and solar are not yet
cost-effective and come with environmental costs of their own (the veteran
British environmentalist David Bellamy is leading opposition to wind
farms).34 The only currently cost-effective alternative to fossil fuel use
is nuclear power, which produces nearly no emissions, but which
environmental activists continue to oppose in direct contradiction to
their assertions that global warming is the gravest danger the planet
faces.
Aren't market-based solutions the way to reduce emissions?
1.. . "Cap and Trade" schemes that allow firms and governments to trade
the right to emit greenhouse gases up to certain limits are not
economically efficient. By creating rent-seeking opportunities, they
promote the development of a carbon cartel seeking to exploit the system
to make profits. The recent collapse of the carbon market in Europe shows
how dependent such markets are on political considerations. A simple
carbon tax would be much more economically efficient, although likely to
prove unattractive to voters in democracies.35
Summary
The world faces severe economic consequences from currently proposed
strategies to deal with global warming. These approaches will produce job
losses and consume scarce resources that could be better spent on handling
other global problems such as AIDS or lack of access to clean drinking
water.36 The economic consequences of global warming mitigation strategies
currently proposed will probably be worse than the effects of global
warming itself. Therefore, adaptation and resiliency strategies should be
considered as a more cost-effective alternative. In addition, "no regrets"
strategies that will provide benefits from greater economic
.

Gosh, you mean Global Warming FACTS without any Knee-Jerk Alarmism?
You mean industry funded lies instead of unbiased scientific conclusions?
http://www.sourcewatch.org/index.php?title=Competitive_Enterprise_Institute
Larry
So you're saying that IPCC is lying when they say:
1.. . There is no "scientific consensus" that global warming will cause
damaging climate change. Claims that there is such a consensus
mischaracterize the scientific research of bodies like the United Nations
Intergovernmental Panel on Climate Change (IPCC) and the U.S. National
Academy of Sciences (NAS).
http://downloads.heartland.org/19381.pdf
Alarm over the prospect of the Earth warming is not warranted by the
agreed science or economics of the issue. Global warming is happening and
man is responsible for at least some of it. Yet this does not mean that
global warming will cause enough damage to the Earth and humanity to
require drastic cuts in energy use, a policy that would have damaging
consequences of its own. Moreover, science cannot answer questions that
are at heart economic or political, such as whether the Kyoto Protocol is
worthwhile.
The Science
Isn't there a scientific consensus that global warming is real and bad
for us?
1.. . There is no "scientific consensus" that global warming will cause
damaging climate change. Claims that there is such a consensus
mischaracterize the scientific research of bodies like the United Nations
Intergovernmental Panel on Climate Change (IPCC) and the U.S. National
Academy of Sciences (NAS).
What do scientists agree on?
1.. . Scientists do agree that: 1) global average temperature is about
0.6°Celsius-or just over 1° Fahrenheit-higher than it was a century ago;
2) atmospheric levels of carbon dioxide (CO2) have risen by about 30
percent over the past 200 years; and 3) carbon dioxide, like water vapor,
is a greenhouse gas whose increase is likely to warm the Earth's
atmosphere.1
Doesn't this mean we should be worried?
1.. . As Richard Lindzen of MIT summarized it in The Wall Street
Journal,2 "These claims are true. However, what the public fails to grasp
is that the claims neither constitute support for alarm nor establish
man's responsibility for the small amount of warming that has occurred.
In fact, those who make the most outlandish claims of alarm are actually
demonstrating skepticism of the very science they say supports them. It
isn't just that the alarmists are trumpeting model results that we know
must be wrong. It is that they are trumpeting catastrophes that couldn't
happen even if the models were right as justifying costly policies to try
to prevent global warming." [Emphasis in original]
2
What don't scientists know yet?
1.. . Scientists do not agree on whether: 1) we know enough to ascribe
past temperature changes to carbon dioxide levels; 2) we have enough data
to confidently predict future temperature levels; and 3) at what level
temperature change might be more damaging than beneficial to life on
Earth.
Didn't the National Academy of Sciences say greenhouse gases cause global
warming?
1.. . The National Academy of Sciences reported in 2001 that, "Because
of the large and still uncertain level of natural variability inherent in
the climate record and the uncertainties in the time histories of the
various forcing agents.a causal linkage between the buildup of greenhouse
gases in the atmosphere and the observed climate changes during the 20th
century cannot be unequivocally established." It also noted that 20
years' worth of data is not long enough to estimate long-term trends. 3
Hasn't the Earth warmed precipitously over the past 100 years?
1.. . The temperature rise of 0.6°C over the last century is at the
bottom end of what climate models suggest should have happened. This
suggests that either the climate is less sensitive to greenhouse gases
than previously thought or that some unknown factor is depressing the
temperature.4
Don't climate models warn of alarming future warming?
1.. . Predictions of 6°C temperature rises over the next 100 years are
at the extreme end of the IPCC range, and are the result of faulty
economic modeling, not science (see economics section below).
What are the realistic current estimates of future warming?
1.. . Both James Hansen of NASA-the father of greenhouse theory-and
Richard Lindzen of MIT-the most renowned climatologist in the world-agree
that, even if nothing is done to restrict greenhouse gases, the world
will only see a global temperature increase of about 1°C in the next
50-100 years. Hansen and his colleagues "predict additional warming in
the next 50 years of 0.5 ± 0.2°C, a warming rate of 0.1 ± 0.04°C per
decade."5
What about satellite temperature measurements?
1.. . Evidence from satellite and weather balloon soundings suggests
that the atmosphere has warmed considerably less than greenhouse theory
suggests.6 These measurements, which cover the whole atmosphere and show
only a very slight warming, show a disparity with the surface temperature
measurements, which cover only a small fraction of the Earth but show
sustained warming.
Hasn't the disagreement between satellite and surface temperatures been
resolved?
1.. . No. There is still substantial disagreement between the mid-range
of the satellite measurements and the mid-range of the surface
measurements. This presents a problem for climate models.
Do other man-made factors besides greenhouse gases influence temperature?
1.. . New research suggests that the role of greenhouse gases in warming
has been overestimated, as factors like atmospheric soot,7 land use
change,8 and solar variation9 all appear to have contributed
significantly to recent warming.
3
The Scare Stories
Is the world in danger of plunging into a new ice age, as in the 2004
movie The Day After Tomorrow?
1.. . No. The scenario presented in The Day After Tomorrow is physically
impossible. While research does suggest that the Gulf Stream has switched
on and off in the past, causing temperature drops in Europe,
oceanographers are convinced that global warming does not present any
such danger.10
Is the world in severe danger from sea level rise?
1.. . No. Research from Nils-Axel Mörner, professor of paleogeophysics
and geodynamics at Stockholm University, demonstrates that current sea
levels are within the range of sea level oscillation over the past 300
years, while the satellite data show virtually no rise over the past
decade.11 The IPCC foresees sea-level rise of between 0.1 and 0.9 meters
by 2100. The Earth experienced a sea-level rise of 0.2 meters over the
past century with no noticeable ill effects.
Another study relevant to this controversy is Zwally et al. (2005),12
which examined changes in ice mass "from elevation changes derived from
10.5 years (Greenland) and 9 years (Antarctica) of satellite radar
altimetry data from the European Remote-sensing Satellites ERS-1 and -2."
The researchers report a net contribution of the three ice sheets to sea
level of +0.05 ± 0.03 millimeters per year. CO2Science.Org puts this in
perspective: "At the current sea-level-equivalent ice-loss rate of 0.05
millimeters per year, it would take a full millennium to raise global sea
level by just 5 cm, and it would take fully 20,000 years to raise it a
single meter."
Weren't recent extreme weather events caused by global warming?
1.. . There is no provable link between weather events like Hurricane
Katrina and global warming. For example, research by German scientists
has demonstrated that the devastating floods in central Europe in 2002
were perfectly normal events when compared against the historical
record.13 Allegations that extreme weather has been more damaging
recently do not take into account the fact that mankind is now living and
investing resources in more dangerous areas. Moreover, the World
Meteorological Organization has acknowledged that increases in the
recorded number of extreme weather events may be due to better
observation and reporting.14 A top expert from the IPCC resigned in
January 2005 in protest that IPCC science was being misrepresented by
claims that last year's hurricane season was exacerbated by global
warming. Most hurricane scientists agree that there is no way that
Hurricane Katrina can be blamed on global warming.
2.. . Recent published research casts extreme doubt on the influence of
warming on hurricanes. Philip Klotzbach15 of Colorado State University
finds that, "The data indicate a large increasing trend in tropical
cyclone intensity and longevity for the North Atlantic basin and a
considerable decreasing trend for the Northeast Pacific. All other basins
showed small trends, and there has been no significant change in global
net tropical cyclone activity. There has been a small increase in global
Category 4-5 hurricanes from the period 1986-1995 to the period
1996-2005. Most of this increase is likely due to improved observational
technology. These findings indicate that other important factors govern
intensity and frequency of tropical cyclones besides SSTs [sea surface
temperatures]."
Aren't the snows of Kilimanjaro disappearing because of global warming?
4
1.. . That's not the verdict of scientists who study Mount Kilimanjaro
most closely. In "Modern Glacier Retreat on Kilimanjaro as Evidence of
Climate Change: Observations and Facts,"16 Kaser et al. "develop a new
concept for investigating the retreat of Kilimanjaro's glaciers, based on
the physical understanding of glacier-climate interactions." They say,
"The concept considers the peculiarities of the mountain and implies that
climatological processes other than air temperature control the ice
recession in a direct manner. A drastic drop in atmospheric moisture at
the end of the 19th century and the ensuing drier climatic conditions are
likely forcing glacier retreat on Kilimanjaro."
Won't global warming lead to the spread of malaria?
1.. . Climate is not a significant factor in the recent growth of
vector-borne diseases such as malaria. Most experts on this subject agree
that malaria is more closely correlated with other factors;
deforestation, migration of lowland people (higher immunities, yet they
bring disease with them), construction of roads and dams, and the
proliferation of pools and ditches are much more important in predicting
future spread of these diseases.17
Didn't the U.S. Department of Defense conclude global warming poses a
national security threat?
1.. . The Pentagon is not convinced that global warming represents a
major security threat to the United States. The "secret paper" that
garnered much publicity in Europe was a self-admitted speculative
exercise that went beyond the bounds of measured research and had been
released to the press long before the sensationalist stories surfaced in
Europe. Nor did the paper recommend "immediate action" beyond better
climate modeling.18
Haven't recent climate models found that global warming will be much
worse than previously thought?
1.. . The news that Oxford University has found that temperatures may
increase by up to 11°C severely misrepresents the scientific findings.
According to the actual scientific paper,19 the frequency distribution of
the results suggests that the lower end of temperature rises, in the 2°C
to 4°C range, is the most likely.
Haven't the National Academies of all the major industrial countries
agreed that global warming is a serious threat?
1.. . Claims have been made that the scientific consensus is represented
by a statement drafted by the Royal Society of London and signed by the
national scientific academies of the G8 countries plus those of India,
Brazil, and China. But such claims ignore the politicized nature of the
statement. The climate change committee of the Russian Academy of
Sciences later said that its president should not have signed the
statement, while the use to which it was put was condemned by the
outgoing president of the U.S. National Academy of Sciences, Bruce
Alberts, who called the Royal Society's presentation of the statement
"quite misleading."20
Aren't polar bears drowning because of melting ice?
1.. . These claims are overblown. A leading Canadian polar bear
biologist wrote recently, "Climate change is having an effect on the west
Hudson population of polar bears, but really, there is no need to panic.
Of the 13 populations of polar bears in Canada, 11 are stable or
increasing in number. They are not going extinct, or even appear to be
affected at present."21
5
Isn't there a scientific consensus such that one researcher found no
disagreement about global warming in the literature?
1.. . The research by Naomi Orsekes published in the journal Science in
December 2004 was flawed. She studied about 1,000 scientific abstracts,
but admitted to a sympathetic journalist that she made a major mistake in
her search terms. In fact, she should have reviewed about 12,000
abstracts. Even taking her sample, another researcher who tried to
replicate her study came to quite different conclusions.22 In addition,
the most recent survey of climate scientists by Dennis Bray and Hans von
Storch, following the same methodology as a published study from 1996,
found that while there had been a move towards acceptance of
anthropogenic global warming, only 9.4 percent of respondents "strongly
agree" that climate change is mostly the result of anthropogenic sources.
A similar proportion "strongly disagree." Furthermore, only 22.8 percent
of respondents "strongly agree" that the IPCC reports accurately reflect
a consensus within climate science.23
There is scientific agreement that the world has warmed and that man is
at least partly responsible for the warming-though there is no consensus

scientific debate over the parameters used by the computer models that
project future climatic conditions. We cannot be certain whether the

Yep.
This statement was, in fact, part of a petitition circulated by the NAS, not
the IPCC. This is one claim of the petition.
However, tis petition has been discredited for , amongst other reasons, the
unscientific method used --- a petition merely signed by dues payers, not
researchers or even experts in the field, and the fact that it is NOT an
official statement of the NAS or the IPCC.
The allegations of IPCC support for this lie really come from two
mongraphs --- that is, discussions, not research papers, supported by no
more than 17 members of the IIPCC.
SO, as usual, you are lying, inflating, misrepresenting, fabricating.

justifying costly policies to try to prevent global warming." [Emphasis
in original]
2
What don't scientists know yet?
1.. . Scientists do not agree on whether: 1) we know enough to ascribe
past temperature changes to carbon dioxide levels; 2) we have enough
data to confidently predict future temperature levels; and 3) at what
level temperature change might be more damaging than beneficial to life
on Earth.
Didn't the National Academy of Sciences say greenhouse gases cause
global warming?
1.. . The National Academy of Sciences reported in 2001 that, "Because
of the large and still uncertain level of natural variability inherent
in the climate record and the uncertainties in the time histories of the
various forcing agents.a causal linkage between the buildup of
greenhouse gases in the atmosphere and the observed climate changes
during the 20th century cannot be unequivocally established." It also
noted that 20 years' worth of data is not long enough to estimate
long-term trends. 3
Hasn't the Earth warmed precipitously over the past 100 years?
1.. . The temperature rise of 0.6°C over the last century is at the
bottom end of what climate models suggest should have happened. This
suggests that either the climate is less sensitive to greenhouse gases
than previously thought or that some unknown factor is depressing the
temperature.4
Don't climate models warn of alarming future warming?
1.. . Predictions of 6°C temperature rises over the next 100 years are
at the extreme end of the IPCC range, and are the result of faulty
economic modeling, not science (see economics section below).
What are the realistic current estimates of future warming?
1.. . Both James Hansen of NASA-the father of greenhouse theory-and
Richard Lindzen of MIT-the most renowned climatologist in the
world-agree that, even if nothing is done to restrict greenhouse gases,
the world will only see a global temperature increase of about 1°C in
the next 50-100 years. Hansen and his colleagues "predict additional
warming in the next 50 years of 0.5 ± 0.2°C, a warming rate of 0.1 ±
0.04°C per decade."5
What about satellite temperature measurements?
1.. . Evidence from satellite and weather balloon soundings suggests
that the atmosphere has warmed considerably less than greenhouse theory
suggests.6 These measurements, which cover the whole atmosphere and show
only a very slight warming, show a disparity with the surface
temperature measurements, which cover only a small fraction of the Earth
but show sustained warming.
Hasn't the disagreement between satellite and surface temperatures been
resolved?
1.. . No. There is still substantial disagreement between the mid-range
of the satellite measurements and the mid-range of the surface
measurements. This presents a problem for climate models.
Do other man-made factors besides greenhouse gases influence
temperature?
1.. . New research suggests that the role of greenhouse gases in
warming has been overestimated, as factors like atmospheric soot,7 land
use change,8 and solar variation9 all appear to have contributed
significantly to recent warming.

The Scare Stories
Is the world in danger of plunging into a new ice age, as in the 2004
movie The Day After Tomorrow?
1.. . No. The scenario presented in The Day After Tomorrow is
physically impossible. While research does suggest that the Gulf Stream
has switched on and off in the past, causing temperature drops in
Europe, oceanographers are convinced that global warming does not
present any such danger.10
Is the world in severe danger from sea level rise?
1.. . No. Research from Nils-Axel Mörner, professor of paleogeophysics
and geodynamics at Stockholm University, demonstrates that current sea
levels are within the range of sea level oscillation over the past 300
years, while the satellite data show virtually no rise over the past
decade.11 The IPCC foresees sea-level rise of between 0.1 and 0.9 meters
by 2100. The Earth experienced a sea-level rise of 0.2 meters over the
past century with no noticeable ill effects.
Another study relevant to this controversy is Zwally et al. (2005),12
which examined changes in ice mass "from elevation changes derived from
10.5 years (Greenland) and 9 years (Antarctica) of satellite radar
altimetry data from the European Remote-sensing Satellites ERS-1
and -2." The researchers report a net contribution of the three ice
sheets to sea level of +0.05 ± 0.03 millimeters per year. CO2Science.Org
puts this in perspective: "At the current sea-level-equivalent ice-loss
rate of 0.05 millimeters per year, it would take a full millennium to
raise global sea level by just 5 cm, and it would take fully 20,000
years to raise it a single meter."
Weren't recent extreme weather events caused by global warming?
1.. . There is no provable link between weather events like Hurricane
Katrina and global warming. For example, research by German scientists
has demonstrated that the devastating floods in central Europe in 2002
were perfectly normal events when compared against the historical
record.13 Allegations that extreme weather has been more damaging
recently do not take into account the fact that mankind is now living
and investing resources in more dangerous areas. Moreover, the World
Meteorological Organization has acknowledged that increases in the
recorded number of extreme weather events may be due to better
observation and reporting.14 A top expert from the IPCC resigned in
January 2005 in protest that IPCC science was being misrepresented by
claims that last year's hurricane season was exacerbated by global
warming. Most hurricane scientists agree that there is no way that
Hurricane Katrina can be blamed on global warming.
2.. . Recent published research casts extreme doubt on the influence of
warming on hurricanes. Philip Klotzbach15 of Colorado State University
finds that, "The data indicate a large increasing trend in tropical
cyclone intensity and longevity for the North Atlantic basin and a
considerable decreasing trend for the Northeast Pacific. All other
basins showed small trends, and there has been no significant change in
global net tropical cyclone activity. There has been a small increase in
global Category 4-5 hurricanes from the period 1986-1995 to the period
1996-2005. Most of this increase is likely due to improved observational
technology. These findings indicate that other important factors govern
intensity and frequency of tropical cyclones besides SSTs [sea surface
temperatures]."
Aren't the snows of Kilimanjaro disappearing because of global warming?
4
1.. . That's not the verdict of scientists who study Mount Kilimanjaro
most closely. In "Modern Glacier Retreat on Kilimanjaro as Evidence of
Climate Change: Observations and Facts,"16 Kaser et al. "develop a new
concept for investigating the retreat of Kilimanjaro's glaciers, based
on the physical understanding of glacier-climate interactions." They
say, "The concept considers the peculiarities of the mountain and
implies that climatological processes other than air temperature control
the ice recession in a direct manner. A drastic drop in atmospheric
moisture at the end of the 19th century and the ensuing drier climatic
conditions are likely forcing glacier retreat on Kilimanjaro."
Won't global warming lead to the spread of malaria?
1.. . Climate is not a significant factor in the recent growth of
vector-borne diseases such as malaria. Most experts on this subject
agree that malaria is more closely correlated with other factors;
deforestation, migration of lowland people (higher immunities, yet they
bring disease with them), construction of roads and dams, and the
proliferation of pools and ditches are much more important in predicting
future spread of these diseases.17
Didn't the U.S. Department of Defense conclude global warming poses a
national security threat?
1.. . The Pentagon is not convinced that global warming represents a
major security threat to the United States. The "secret paper" that
garnered much publicity in Europe was a self-admitted speculative
exercise that went beyond the bounds of measured research and had been
released to the press long before the sensationalist stories surfaced in
Europe. Nor did the paper recommend "immediate action" beyond better
climate modeling.18
Haven't recent climate models found that global warming will be much
worse than previously thought?
1.. . The news that Oxford University has found that temperatures may
increase by up to 11°C severely misrepresents the scientific findings.
According to the actual scientific paper,19 the frequency distribution
of the results suggests that the lower end of temperature rises, in the
2°C to 4°C range, is the most likely.
Haven't the National Academies of all the major industrial countries
agreed that global warming is a serious threat?
1.. . Claims have been made that the scientific consensus is
represented by a statement drafted by the Royal Society of London and
signed by the national scientific academies of the G8 countries plus
those of India, Brazil, and China. But such claims ignore the
politicized nature of the statement. The climate change committee of the
Russian Academy of Sciences later said that its president should not
have signed the statement, while the use to which it was put was
condemned by the outgoing president of the U.S. National Academy of
Sciences, Bruce Alberts, who called the Royal Society's presentation of
the statement "quite misleading."20
Aren't polar bears drowning because of melting ice?
1.. . These claims are overblown. A leading Canadian polar bear
biologist wrote recently, "Climate change is having an effect on the
west Hudson population of polar bears, but really, there is no need to
panic. Of the 13 populations of polar bears in Canada, 11 are stable or
increasing in number. They are not going extinct, or even appear to be
affected at present."21
5
Isn't there a scientific consensus such that one researcher found no
disagreement about global warming in the literature?
1.. . The research by Naomi Orsekes published in the journal Science in
December 2004 was flawed. She studied about 1,000 scientific abstracts,
but admitted to a sympathetic journalist that she made a major mistake
in her search terms. In fact, she should have reviewed about 12,000
abstracts. Even taking her sample, another researcher who tried to
replicate her study came to quite different conclusions.22 In addition,
the most recent survey of climate scientists by Dennis Bray and Hans von
Storch, following the same methodology as a published study from 1996,
found that while there had been a move towards acceptance of
anthropogenic global warming, only 9.4 percent of respondents "strongly
agree" that climate change is mostly the result of anthropogenic
sources. A similar proportion "strongly disagree." Furthermore, only
22.8 percent of respondents "strongly agree" that the IPCC reports
accurately reflect a consensus within climate science.23
There is scientific agreement that the world has warmed and that man is
at least partly responsible for the warming-though there is no consensus
on the precise extent of man's effect on the climate. There is ongoing
scientific debate over the parameters used by the computer models that
project future climatic conditions. We cannot be certain whether the
world will warm significantly and we do not know how damaging-if at
all-even significant warming will be.
The Economics
Why is economics important to the study of global warming?
1.. . Predictions of global warming catastrophe are based on models
that rely on economics as much as on science. If the science of
greenhouse theory is right, then we can only assess its consequences by
estimating future production of greenhouse gases from estimates of
economic activity.
Is there anything wrong with the economics underlying warming
projections?
1.. . The economic modeling by the U.N. Intergovernmental Panel on
Climate Change is seriously flawed (The Economist called it "dangerously
incompetent"), relying on economic forecasts that show much faster
growth rates for developing countries than is justified.24 The IPCC
economic scenarios show significantly greater economic growth globally
than do other recognized, comparable scenarios.
What will the Kyoto Protocol do to reduce warming?
1.. . The Kyoto Protocol, most observers agree, will have virtually no
effect on temperature increase, as it imposes no restrictions on
greenhouse gas emissions upon major developing nations like China and
India. These nations have publicly refused to accept any restrictions
now or in the future.25
Can't we reduce emissions without affecting the economy?
1.. . Greenhouse gas emissions derive from energy use which in turn
derives from economic growth. Therefore, nations that restrict emissions
are almost certain to reduce their rate of economic growth.
Isn't global warming all cost and no benefit?
6
1.. . No. Even substantial global warming is likely to be of benefit to
the United States. As eminent Yale Professor Robert Mendehlson testified
before the Senate in 2000,26 "Climate change is likely to result in
small net benefits for the United States over the next century. The
primary sector that will benefit is agriculture. The large gains in this
sector will more than compensate for damages expected in the coastal,
energy, and water sectors, unless warming is unexpectedly severe.
Forestry is also expected to enjoy small gains. Added together, the
United States will likely enjoy small benefits of between $14 and $23
billion a year and will only suffer damages in the neighborhood of $13
billion if warming reaches 5°C over the next century. Recent predictions
of warming by 2100 suggest temperature increases of between 1.5°C and
4°C, suggesting that impacts are likely to be beneficial in the U.S."
Haven't economic models predicted no effect of reducing emissions on
growth?
1.. . European models of the effect of greenhouse gas emission
restrictions (such as PRIMES) are sectoral models that look at the
effects on only one economic sector and therefore badly underestimate
the negative effects of emission restrictions throughout the economy.
General equilibrium models, which take into account the effects of
emissions restrictions on other economic sectors, show much greater
negative economic effects than do sectoral models.27
What do the better economic models say Kyoto will do?
1.. . Recent research from general equilibrium models suggests strongly
negative impacts on European economies from adopting Kyoto targets (or
going beyond the targets, as in the case of the United Kingdom). One
model shows the economic effects by 2010 of adopting Kyoto targets as
follows (remember that the Protocol achieves virtually nothing in
reducing global temperature):28
Germany -5.2% GDP -1,800,000 jobs
Spain -5.0% GDP -1,000,000 jobs
United Kingdom -4.5% GDP -1,000,000 jobs
Netherlands -3.8% GDP -240,000 jobs
Isn't Europe on track to meet its Kyoto targets?
1.. . Kyoto targets are unrealistic. Regardless of announced targets,
11 of the 15 pre-enlargement EU countries are on course to increase
their greenhouse gas emissions well beyond their individual Kyoto
targets.29
Specific Economic Issues
Isn't President Bush to blame for holding up Kyoto?
1.. . It is not the case that President Bush has unilaterally held up
ratification of the Kyoto treaty. The United States Senate must ratify
any treaty signed by a President. In 1997, during Bill Clinton's
presidency, the Senate (including recent Democratic presidential
candidate John Kerry) voted 95-0 not to accept any Kyoto-style treaty
that would significantly harm the U. S. economy and did not include
participation by major developing countries.30 The U.S. President has no
power to impose Kyoto, or any other treaty, on an unwilling Senate.31
Doesn't Russia's participation demonstrate the appeal of Kyoto?
7
1.. . Russia agreed to ratify the Kyoto Protocol only after being
pressured by the European Union, which held out the prospect of
endorsing Russia's entry into the World Trade Organization. Both the
Russian Academy of Sciences and several Duma committees reported that
Kyoto has no scientific substantiation and may harm Russia's economy.32
Isn't global warming a worse threat than terrorism?
1.. . The charge that global warming is worse than terrorism in terms
of damage to the world is hyperbole. The implausible and unsubstantiable
claim of many deaths each year-the figure is often put at 150,000-owing
to global warming ignores the fact that most of those alleged deaths are
due to diseases such as malaria, which have historically existed even in
cold climates and could easily be controlled if the environmental lobby
dropped its opposition to the use of DDT.33 Moreover, that number is
itself dwarfed by the number killed by poverty, which will be increased
if the world decides to suppress the use of energy.
Can't we replace fossil fuels cheaply and effectively with renewable
energy?
1.. . Alternative sources of energy such as wind and solar are not yet
cost-effective and come with environmental costs of their own (the
veteran British environmentalist David Bellamy is leading opposition to
wind farms).34 The only currently cost-effective alternative to fossil
fuel use is nuclear power, which produces nearly no emissions, but which
environmental activists continue to oppose in direct contradiction to
their assertions that global warming is the gravest danger the planet
faces.
Aren't market-based solutions the way to reduce emissions?
1.. . "Cap and Trade" schemes that allow firms and governments to trade
the right to emit greenhouse gases up to certain limits are not
economically efficient. By creating rent-seeking opportunities, they
promote the development of a carbon cartel seeking to exploit the system
to make profits. The recent collapse of the carbon market in Europe
shows how dependent such markets are on political considerations. A
simple carbon tax would be much more economically efficient, although
likely to prove unattractive to voters in democracies.35
Summary
The world faces severe economic consequences from currently proposed
strategies to deal with global warming. These approaches will produce
job losses and consume scarce resources that could be better spent on
handling other global problems such as AIDS or lack of access to clean
drinking water.36 The economic consequences of global warming mitigation
strategies currently proposed will probably be worse than the effects of
global warming itself. Therefore, adaptation and resiliency strategies
should be considered as a more cost-effective alternative. In addition,
"no regrets" strategies that will provide benefits from greater economic
.

Gosh, you mean Global Warming FACTS without any Knee-Jerk Alarmism?
You mean industry funded lies instead of unbiased scientific
conclusions?
http://www.sourcewatch.org/index.php?title=Competitive_Enterprise_Institute
Larry
So you're saying that IPCC is lying when they say:
1.. . There is no "scientific consensus" that global warming will cause
damaging climate change. Claims that there is such a consensus
mischaracterize the scientific research of bodies like the United Nations
Intergovernmental Panel on Climate Change (IPCC) and the U.S. National
Academy of Sciences (NAS).
Yep.
This statement was, in fact, part of a petitition circulated by the NAS,
not the IPCC. This is one claim of the petition.
However, tis petition has been discredited for , amongst other reasons,
the unscientific method used --- a petition merely signed by dues payers,
not researchers or even experts in the field, and the fact that it is NOT
an official statement of the NAS or the IPCC.
The allegations of IPCC support for this lie really come from two
mongraphs --- that is, discussions, not research papers, supported by no
more than 17 members of the IIPCC.
SO, as usual, you are lying, inflating, misrepresenting, fabricating.
Larry
I merely posted information by a credible source, so you're really calling
them liars. But that's ok cause liberals are so filled with hate that you
just can't help yourself!
http://downloads.heartland.org/19381.pdf
Alarm over the prospect of the Earth warming is not warranted by the
agreed science or economics of the issue. Global warming is happening
and man is responsible for at least some of it. Yet this does not mean
that global warming will cause enough damage to the Earth and humanity
to require drastic cuts in energy use, a policy that would have
damaging consequences of its own. Moreover, science cannot answer
questions that are at heart economic or political, such as whether the
Kyoto Protocol is worthwhile.
The Science
Isn't there a scientific consensus that global warming is real and bad
for us?
1.. . There is no "scientific consensus" that global warming will
cause damaging climate change. Claims that there is such a consensus
mischaracterize the scientific research of bodies like the United
Nations Intergovernmental Panel on Climate Change (IPCC) and the U.S.
National Academy of Sciences (NAS).
What do scientists agree on?
1.. . Scientists do agree that: 1) global average temperature is about
0.6°Celsius-or just over 1° Fahrenheit-higher than it was a century
ago; 2) atmospheric levels of carbon dioxide (CO2) have risen by about
30 percent over the past 200 years; and 3) carbon dioxide, like water
vapor, is a greenhouse gas whose increase is likely to warm the Earth's
atmosphere.1
Doesn't this mean we should be worried?
1.. . As Richard Lindzen of MIT summarized it in The Wall Street
Journal,2 "These claims are true. However, what the public fails to
grasp is that the claims neither constitute support for alarm nor
establish man's responsibility for the small amount of warming that has
occurred. In fact, those who make the most outlandish claims of alarm
are actually demonstrating skepticism of the very science they say
supports them. It isn't just that the alarmists are trumpeting model
results that we know must be wrong. It is that they are trumpeting
catastrophes that couldn't happen even if the models were right as
justifying costly policies to try to prevent global warming." [Emphasis
in original]
2
What don't scientists know yet?
1.. . Scientists do not agree on whether: 1) we know enough to ascribe
past temperature changes to carbon dioxide levels; 2) we have enough
data to confidently predict future temperature levels; and 3) at what
level temperature change might be more damaging than beneficial to life
on Earth.
