Hello. I think we are a little more grown up than use an unsubstentiated
statement with another unsubstentiated statement. The list of "facts" and
"myths" sounds like:
Myth: The earth is round.
Fact: The earth is flat. All the houses are measured in sq ft.
Time to Grow up.

Subject: [Reader-list] 10 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,
> is well within the natural variations recorded in the last millennium. The
> ground station network suffers from an uneven distribution across the
> 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
> global temperature" has been rising at the low steady rate mentioned
> although from 1940 1970 temperatures actually dropped, leading to a
> 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
> 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
> naturally and cyclically through solar radiation, orbital and galactic
> influences, the warming surface layers of the earth's oceans expel more
> 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
> remainder being gases like CO2, CH4, Ozone and N2O, of which carbon
> is the largest amount. Hence, CO2 constitutes about 0.037% of the
> atmosphere. While the minor gases are more effective as "greenhouse
> 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
> of the "Greenhouse effect".
> Those attributing climate change to CO2 rarely mention this important
> 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.
> 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
> Medieval Warm Period. Varying intensity of solar heat radiation affects
> 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 manmade 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 manmade 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.
> 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
> 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
> 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. Its normal. Besides, glacier's health is dependent as
> on precipitation as on temperature.
> MYTH 10: The earths 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
> Arctic and Greenland are getting colder. The small Palmer Peninsula of
> Antarctica is getting warmer, while the main Antarctic continent is
> 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.
