TEN MYTHS of Global Warming

MYTH 1: Global temperatures are rising at a rapid, unprecedented
rate.

FACT: Accurate satellite, balloon and mountain top observations made
over the last three decades have not shown any significant change in
the long term rate of increase in global temperatures. Average ground
station readings do show a mild warming of 0.6 to 0.8Cover the last
100 years, which is well within the natural variations recorded in the
last millennium. The ground station network suffers from an uneven
distribution across the globe; the stations are preferentially located
in growing urban and industrial areas ("heat islands"), which show
substantially higher readings than adjacent rural areas ("land use
effects").

There has been no catastrophic warming recorded.

MYTH 2: The "hockey stick" graph proves that the earth has
experienced a steady, very gradual temperature increase for 1000
years, then recently began a sudden increase.

FACT: Significant changes in climate have continually occurred
throughout geologic time. For instance, the Medieval Warm Period, from
around 1000 to1200 AD (when the Vikings farmed on Greenland) was
followed by a period known as the Little Ice Age. Since the end of the
17th Century the "average global temperature" has been rising at the
low steady rate mentioned above; although from 1940 - 1970
temperatures actually dropped, leading to a Global Cooling scare.

The "hockey stick", a poster boy of both the UN's IPCC and Canada's
Environment Department, ignores historical recorded climatic swings,
and has now also been proven to be flawed and statistically unreliable
as well. It is a computer construct and a faulty one at that.

MYTH 3: Human produced carbon dioxide has increased over the last 100
years, adding to the Greenhouse effect, thus warming the earth.

FACT: Carbon dioxide levels have indeed changed for various reasons,
human and otherwise, just as they have throughout geologic time. Since
the beginning of the industrial revolution, the CO2 content of the
atmosphere has increased. The RATE of growth during this period has
also increased from about 0.2%% per year to the present rate of about
0.4%% per year,which growth rate has now been constant for the past 25
years. However, there is no proof that CO2 is the main driver of
global warming. As measured in ice cores dated over many thousands of
years, CO2 levels move up and down AFTER the temperature has done so,
and thus are the RESULT OF, NOT THE CAUSE of warming. Geological field
work in recent sediments confirms this causal relationship. There is
solid evidence that, as temperatures move up and down naturally and
cyclically through solar radiation, orbital and galactic influences,
the warming surface layers of the earth's oceans expel more CO2 as a
result.

MYTH 4: CO2 is the most common greenhouse gas.

FACT: Greenhouse gases form about 3 %% of the atmosphere by volume.
They consist of varying amounts, (about 97%%) of water vapour and
clouds, with the remainder being gases like CO2, CH4, Ozone and N2O,
of which carbon dioxide is the largest amount. Hence, CO2 constitutes
about 0.037%% of the atmosphere. While the minor gases are more
effective as "greenhouse agents" than water vapour and clouds, the
latter are overwhelming the effect by their sheer volume and - in the
end - are thought to be responsible for 60%% of the "Greenhouse
effect".
Those attributing climate change to CO2 rarely mention this important
fact.

MYTH 5: Computer models verify that CO2 increases will cause
significant global warming.

FACT: Computer models can be made to "verify" anything by changing
some of the 5 million input parameters or any of a multitude of
negative and positive feedbacks in the program used.. They do not
"prove" anything. Also, computer models predicting global warming are
incapable of properly including the effects of the sun, cosmic rays
and the clouds. The sun is a major cause of temperature variation on
the earth surface as its received radiation changes all the time, This
happens largely in cyclical fashion. The number and the lengths in
time of sunspots can be correlated very closely with average
temperatures on earth, e.g. the Little Ice Age and the Medieval Warm
Period. Varying intensity of solar heat radiation affects the surface
temperature of the oceans and the currents. Warmer ocean water expels
gases, some of which are CO2. Solar radiation interferes with the
cosmic ray flux, thus influencing the amount ionized nuclei which
control cloud cover.

MYTH 6: The UN proved that man-made CO2 causes global warming.
FACT: In a 1996 report by the UN on global warming, two statements
were deleted from the final draft. Here they are:
1) "None of the studies cited above has shown clear evidence that
we can attribute the observed climate changes to increases in
greenhouse gases."
2) "No study to date has positively attributed all or part of the
climate change to man-made causes"

To the present day there is still no scientific proof that man-made
CO2 causes significant global warming.

MYTH 7: CO2 is a pollutant.

FACT: This is absolutely not true. Nitrogen forms 80%% of our
atmosphere. We could not live in 100%% nitrogen either. Carbon dioxide
is no more a pollutant than nitrogen is. CO2 is essential to life on
earth. It is necessary for plant growth since increased CO2 intake as
a result of increased atmospheric concentration causes many trees and
other plants to grow more vigorously. Unfortunately, the Canadian
Government has included CO2 with a number of truly toxic and noxious
substances listed by the Environmental Protection Act, only as their
means to politically control it.

MYTH 8: Global warming will cause more storms and other weather
extremes.

FACT: There is no scientific or statistical evidence whatsoever that
supports such claims on a global scale. Regional variations may
occur. Growing insurance and infrastructure repair costs, particularly
in coastal areas, are sometimes claimed to be the result of increasing
frequency and severity of storms, whereas in reality they are a
function of increasing population density, escalating development
value, and ever more media reporting.

MYTH 9: Receding glaciers and the calving of ice shelves are proof of
global warming.

FACT: Glaciers have been receding and growing cyclically for
hundreds of years. Recent glacier melting is a consequence of coming
out of the very cool period of the Little Ice Age. Ice shelves have
been breaking off for centuries. Scientists know of at least 33
periods of glaciers growing and then retreating. It's normal. Besides,
glacier's health is dependent as much on precipitation as on
temperature.

MYTH 10: The earth's poles are warming; polar ice caps are breaking
up and melting and the sea level rising.

FACT: The earth is variable. The western Arctic may be getting
somewhat warmer, due to unrelated cyclic events in the Pacific Ocean,
but the Eastern Arctic and Greenland are getting colder. The small
Palmer Peninsula of Antarctica is getting warmer, while the main
Antarctic continent is actually cooling. Ice thicknesses are
increasing both on Greenland and in Antarctica.

Sea level monitoring in the Pacific (Tuvalu) and Indian Oceans
(Maldives) has shown no sign of any sea level rise.

Live Earth's Inconvenient Truths
by Patrick Basham

Patrick Basham directs the Democracy Institute, teaches research
methods at Johns Hopkins University and is a Cato Institute adjunct
scholar.

The theme of Saturday's worldwide Live Earth concerts was a call for
action against climate change. The Intergovernmental Panel on Climate
Change's recent reports, heralded as the final word on global warming,
inspired both organizers and performers, from Al Gore to Madonna.

Opening the Washington concert leg, Mr. Gore denounced climate change
skeptics "who don't understand what is now at stake." Strong words
from a public figure flaunting an Oscar comprised of junk science.

Sadly, the IPCC encouraged deeply disturbing departures from sound
scientific research that significantly undermine Live Earth's alarmist
message. Yet, the problems with the IPCC report go much further than
politicized science. They extend to the core of the climate change
debate, namely the degree of scientific certainty about the causes and
consequences of global warming.

Scientific uncertainty: What level of scientific certainty do IPCC's
global warming claims really have?

The gold standard level of scientific certainty is the 95 percent
confidence level. This allows a researcher to attest that he or she is
95 percent confident his or her findings are genuine and not due to
chance. Claims that fail to meet this standard carry little scientific
weight.

Applying this scientific concept to the IPCC report reveals how
uncertain are the alarmists' claims. For example, not a single IPCC
conclusion about the human sources of global warming meets a 95
percent confidence level standard.

There are, however, 26 claims termed "likely," meaning their chance of
being true is greater than 66 percent. To put this into context, you
might ask yourself how comfortable you would feel driving a car whose
brakes worked only 14 times out of 20.

This has importance for understanding how much genuine scientific
knowledge, as opposed to mere political posturing, the IPCC report
offers. For example, the key claim - that there has been significant
human-caused warming over the last 50 years - is merely "likely,"
according to the IPCC.

Not one of the IPCC's seven projected man-made weather trends reaches
a 95 percent confidence level. This fact makes implausible the claim
that human activity is the driver of climate change.

Politicized science: The IPCC's Rules of Procedure mandate not the
normal scholarly peer review process but "review by governments."
Furthermore, the IPCC states that, "In taking decisions and approving,
adopting and accepting reports, the Panel, its Working Groups and any
Task Force shall use all best endeavors to reach consensus."

Both rules suggest something other than a process committed to sound
science. Science does not proceed by consensus or government review
but by reliably replicable, public results always open to doubt and
falsification.

Injecting government review into the scientific process corrupts the
process by switching from one in which science drives policy to one in
which policy drives science. In truth, these rules reveal the IPCC
process for what it really is: politicized science in the service of
government, rather than science in the service of the truth.

Some commentators say casting doubt on the science of climate change
is the equivalent of Holocaust denial. Such thinking can only come
from those who either fail to understand or choose to disown the
scientific enterprise.

At the heart of the scientific enterprise is a curious and always
difficult tension between certainty and the possibility that certainty
can suddenly dissolve. Respectful of that tension, the climate change
skeptic asks for two things: first, to bring the normal standards of
scientific evidence to the climate debate; and, second, to make
certain there is not some politically driven and premature closure of
what is a scientific controversy.

Live Earth's inconvenient truth is that Al Gore and his friends are
wrong about the strength of the climate change evidence. Using normal
scientific standards, there is no proof we are causing the Earth to
warm, let alone that such warming will cause an environmental
catastrophe. To claim otherwise is to be untrue to the skepticism at
the heart of science.
