  • Or is it just hot air?

  • According to the U.N., some environmental
    activists, and even some governments, the
    greatest threat facing mankind is global warming.
    The earth is warming at an unprecedented rate
    and will soon become unlivable, sea levels will
    rise, crops will fail, weather will become wild
    and unpredictable.

  • There are ominous signs that the Earths
    weather patterns have begun to change
    dramaticallywith serious political implications
    for just about every nation on earth.- Newsweek
    April 28, 1975
  • Present climate is highly abnormalThere is a
    finite possibility that a serious worldwide
    cooling could befall the earth within the next
    hundred years.
  • - National Academy of Sciences, 1975
  • If present trends continue, the world will be
    about four degrees colder for the global mean
    temperature in 1990, but eleven degrees colder by
    the year 2000.This is about twice what it would
    take to put us in an ice age.
  • - Kenneth E. F. Watt on air pollution and global
    cooling, Earth Day 1970

  • The earth has had stable temperatures for a long
    time, and the 20th century has seen a dramatic
    rise in temperature, in the shape of a hockey

  • The math behind the hockey stick shaped graph
    has been proven wrong by Canadian statisticians
    Stephen McIntyre and Ross McKitrick. Here are 4
    graphs. One is the global warming hockey stick
    used by the UN and governments around the world
    to justify Kyoto, the other ones use the same
    computer program, with COMPLETELY RANDOM data.
  • Which one is which?

  • The 1990s were the hottest years ever recorded
    on earth, and this was caused by human greenhouse
    gas emissions.

Global Warming Fact 2
  • Why then, did the global temperature of the
    earth decline from 1940 to the late 1970s
    (causing the global cooling scare)? During which
    time the human emissions of CO2 were increasing
    like crazy (due to increased industrialization
    after WWII).
  • The Earth is actually coming out of a cold
    period, known as the Little Ice Age. Global
    climate has been colder than present. It has
    also been warmer and that warmth had nothing to
    do with man-made CO2.

Global Warming Myth 3
  • The consensus of world scientists is that
    humanity is causing significant climate change.
  • The overwhelming majority of scientific
    experts, whilst recognizing that scientific
    uncertainties exist, nonetheless believe that
    human-induced climate change is already occurring
    and that future change is inevitable.
  • - Robert T. Watson, Chairman of the
    Intergovernmental Panel on Climate Change (IPCC)
    in November, 2000
  • The consensus is that global warming is real,
    that it's happening and that we humans -- with
    our cars, and especially our power plants,
    burning coal, oil and gas, and releasing carbon
    dioxide into the atmosphere -- are partly or
    mostly or entirely responsible.

Global Warming Fact 3
  • There is no consensus!
  • Oregon Global Warming Petition - Signed by more
    than 17,100 basic and applied American
    scientists, two-thirds with advanced degrees
  • - Urges the United States government to reject
    the global warming agreement that was written in
    Kyoto, Japan in December, 1997, and any other
    similar proposals
  • http//
  • Heidelberg Appeal States there is no
    scientific evidence for man-made global warming
  • - Started in 1992, it has now been signed by
    more than 4000 scientists from around the world

Global Warming Myth 4
  • Global Warming will be disastrous for the
    environment and human society
  • Warming is bringing unpredictable changes.
    Melting glaciers and precipitation are causing
    some rivers to overflow Diseases are spreading.
    Some crops grow faster while others see yields
    slashed by disease and drought. Clashes over
    dwindling water resources may cause conflicts
  • Thermal expansion of the oceans, combined with
    melting ice on land, is also raising sea levels.
    In this century, human activity could trigger an
    irreversible melting of the Greenland ice sheet.
    This would condemn the world to a rise in sea
    level of six meters - enough to flood land
    occupied by billions of people.

Global Warming Fact 4
  • Dr. Tim Patterson, Professor of earth sciences
    (Paleoclimatology) at Carleton University, and
    climate historian Hubert H. Lamb demonstrate that
    during warm periods civilization flourished and
    weather was more moderate. In cold periods, there
    was more drought, famine, wars and disease.
  • Between 900 and 1300 A.D., the Earth warmed 1
    to 2Capproximately what climate models now
    predict for the 21st century. This warming
    resulted in one of the most favorable periods in
    history. Food production surged due to mild
    winters and longer growing seasons. Primary
    agricultural regions had fewer droughts and
    floods When Erik the Red was exiled from Iceland
    for murder in 980 AD, he was fortunate that his
    banishment coincided with this unusually warm
    climatic period. Open sea-lanes allowed him to
    make his way to a wholly new and, at the time,
    reasonably hospitable land - calling it

Global Warming Myth 5
  • Extreme weather events will become more and more
    common as the world warms. This can already be
    seen with the increase of drought, floods, forest
    fires, hurricanes, tornadoes, and tsunamis.
  • Extreme weather threatens Canadian ecosystems,
    security and health, and imposes severe costs on
    key sectors of our economyThe cost of
    weather-related disasters in Canada increased
    significantly during the 1990s. A number of
    sectors in the Canadian economy including
    forestry, agriculture and fisheries can be
    easily devastated by climate change-induced
    weather disasters. Government of Canada,
    Project Green Moving Forward on Climate Change,

Global Warming Fact 5
  • Could the increased costs be due to people
    building structures in extreme weather prone
    areas such as floodplains and tornado alleys, and
    not due to increased extreme weather events?
  • Dr. Madhav Khandekar, a meteorologist with 25
    years experience at Environment Canada, has
    showed that extreme weather events (heat waves,
    floods, winter blizzards, thunderstorms, hail,
    tornadoes) are not currently increasing anywhere
    in Canada. "Extreme weather events are definitely
    on the decline over the last 40 years," concludes
    Dr. Khandekar.
  • According to Dr. John Christy, Professor and
    Director, Earth System Science Center at the
    University of Alabama, the frequency of
    hurricanes, thunderstorms, hail and tornadoes
    have not increased in recent years either.
    Weather just seems unusual and dangerous these
    days because of media focus. If the planet warms,
    the temperature differential between the Earth's
    poles and equatorial regions will drop, resulting
    in weather that is even more tranquil.

Global Warming Myth 6
  • Alternative energy sources such as solar, wind,
    tidal, and hydrogen cells can soon be significant
    contributors to the energy needs of the human

Global Warming Fact 6
  • Environmentalists tell us that we can break the
    fossil fuel habit by massively expanding our use
    of "clean" wind and solar power to provide much
    of Canada's power needs. Unfortunately, this is
    hopelessly impractical. Both of these energy
    sources are far too diffuse and intermittent to
    ever provide more than a small fraction of the
    energy needs of any major industrialized nation,
    let alone vast, northern countries like Canada
    and United States. The problems of diffuseness
    and intermittency are ones that can never be
    completely overcome, no matter how much research
    and development is done in the field.
  • "To produce an average of 1000 MW, the power
    produced by any large conventional (coal, oil,
    nuclear, gas) power plant, would require about
    833 square kilometers of wind turbines. That's
    the area of a mile-wide swath of land extending
    from San Francisco to Los Angeles. Multiply that
    by about 30 and you have California's
    electricity. - Dr. Howard C. Hayden, Emeritus
    Professor of Physics, University of Connecticut
  • Consider that in 2001 there was a total global
    installed capacity of eight gigawatts (GW) of
    geothermal power, 25 GW of wind power and
    negligible photovoltaic solar power. Even
    assuming the wind blows all the time, geothermal,
    wind and photovoltaic add up to only one quarter
    of one per cent of worldwide primary energy
    production. To replace fossil fuels, you would
    need to increase all these renewables by a
    staggering 33,000 per cent!

  • Kyoto will reduce air pollution and will save
  • Climate change is already killing 150,000 people
    a year.

  • Climate change is likely to have wide-ranging
    and mostly adverse impacts on human health, with
    significant loss of life

Global Warming Fact 7
Kyoto is about greenhouse gases only. Kyoto only
addresses carbon dioxide, methane, nitrous oxide,
hydrofluorocarbons, perfluorocarbons, and sulfur
hexafluoride. It does not address any SOX or NOX
particulate matter, nor does it address ozone,
the main cause of smog. Thus, Kyoto will not
reduce atmospheric pollution, it will only
attempt to reduce the amount of CO2 emitted by
human activities. The irony is that CO2 is
required by all primary life (plants) to grow.
Without it, there would be no plant or animal
life on earth.

To Help Fight Kyoto
  • 1) Write letters to your elected government
    officials, as well as to the editor of your local
    newspaper and the media, and contribute to
    websites and blogs as well as other avenues of
    communication, that you dont want Kyoto
    implemented, and you want a real solution to real
    pollution, which CO2 is not.
  • 2) Visit the Friends of Science at often, to keep up to
    date and join us in fighting against the abuse of
    science and promotion of hysteria.
