The Great Global Warming Swindle
Carbon Dioxide is not the Culprit!
The Greenhouse Effect
Man-made global warming is no longer just a theory about climate, it
is a defining moral and political cause of our age. Campaigners say the
time for debate is over and any criticism, no matter how scientifically rigorous,
is illegitimate, even worse dangerous.
Everywhere we are being told that man-made climate change is proved
beyond doubt. But, we are being told lies!
Professor Tim Ball of the Department of Climatology at the University
of Winnipeg "When people say I don't believe in global warming, I
tell them that I believe in global warming but I don't believe human
generated CO² is causing that warming".
Each day the news reports grow more fantastically apocalyptic.
Politicians no longer dare to express any doubt about climate change.
Global warming has gone beyond politics, it is a new kind of morality.
Yet, as the frenzy over man-made global warming grows ever shriller,
many senior climate scientists say the actual scientific basis for the
theory is crumbling.
Professor Nir Shaviv of the Institute of Physics at Jerusalem
University points out "There are periods in Earth's history where we
had three times as much CO² as we have today or periods where we had ten
times the CO² we have today. If CO² has a large effect on climate then we
should see it in the temperature reconstruction".
Prof. John Christy
Professor John Christy former Lead Author with the IPCC agrees
"I've often heard it said that there's a consensus of thousands of
scientists on the global warming issue who think humans are causing a catastrophic
change in the climate system. Well I am one scientist, and I know of
many others, who simply think this is not true".
Man-made global warming is no ordinary scientific theory. It is
presented in the media as having the stamp of authority from an
impressive international organisation; The United Nations Inter
Governmental Panel on Climate Change or IPCC.
Professor Philip Stott from the University of London disagrees
"The IPCC, like any UN body, is political. The final conclusions
are politically driven". Professor Paul Reiter of the Pasteur Institute
adds "The IPCC claim to have the world's top 1500 or 2500
scientists is misleading. You look at the bibliographies and find that
many of them are non-scientists".
Patrick Moore, the co-founder of Greenpeace is disillusioned "I
don't like to call it an environmental movement anymore, because really
it is a political activist movement and they have become hugely
influential at a global level".
This has become a distortion of a whole area of science, how a
political campaign has become a bureaucratic bandwagon, about censorship
and intimidation and how westerners are invoking the threat of climatic
disaster to hinder vital industrial progress in developing countries.
We are told that the Earth's climate is changing. But the Earth's
climate is always changing. In Earth's long history there have been
countless periods when it was much warmer and much cooler than it is
today. When much of the world was covered by tropical forests or else
vast ice-sheets. The climate has always changed, and changed without
help from us humans.
We can trace the current warming trend back some 200 years, to the
end of a very cold period in Earth's history. This cold spell is known
to climatologists as "The Little Ice-Age".
If we look back further in time we find a balmy golden era when
temperatures were higher than they are today. A time known as "The
Medieval Warm Period".
Further back still we find a period during The Bronze Age, known to
geologists as "The Holocene Maximum" where temperatures were
significantly higher for three millennia.
Climate variation in the past is clearly natural, so why do we think
it is any different today? In the current panic about global warming,
the culprit is an industrial society Luxuries once enjoyed exclusively
by the rich are now available to all. Industrial progress has changed
our lives, but has it also changed our climate?
The Industrial Revolution really began after the Second World War
which was followed by four decades of temperature decrease. This
confounds the theory somewhat.
Since the mid 19th century, the Earth's temperature has risen by
about half a degree Celsius. This warming began long before cars and
planes had been invented. What's more, most of the rise in temperature
occurred before 1940 when industrial production was relatively
insignificant.
Why do we suppose that carbon dioxide is responsible for our changing
climate? CO2 forms only a very small part of the Earth's atmosphere. In
fact changes in CO² levels are measured in tens of parts per million. It
measures about 0.054% of the atmosphere.
Although CO² is a greenhouse gas, it is a relatively minor one, water
vapour is, by far, the biggest player
A scientist largely responsible for measuring the Earth's atmosphere
is Professor John Christy. In 1991, he was awarded NASA's Medal for
Exceptional Scientific Achievement and in 1996 he received a Special
Award from the American Meteorological Society for fundamentally
advancing our ability to monitor climate. He reports "What we've found,
consistently, in a great part of the planet, is that the atmosphere is
not warming as much as we see on the surface". This suggests that the
warming is not a result of greenhouse gases.
Former Vice-President Al Gore's film "An Inconvenient Truth" is
widely regarded as the definitive popular presentation on the theory of
man-made global warming. His argument rests on one all-important piece
of evidence taken from ice-core surveys These ice-cores trap climate
information from hundreds of thousands of years ago. The first ice-core
survey took place in Vostok, Antarctica. What it found was, as Al Gore
pointed out, a direct correlation between carbon dioxide levels and
temperature. But there was one important factor in the ice-core data
that Al Gore failed to mention.
Carbon Dioxide Lag
When the ice-core data was analysed in detail, it could be seen that
the changes in temperature occurred about 800 year before the
corresponding changes in CO². Al Gore's presentation had the data the
wrong way around. Carbon Dioxide is not the cause of temperature
change, it is a product of it.
Carbon dioxide is not a pollutant, it is a natural gas essential to
every living organism on the planet. Humans are not the largest
producers of CO². Volcanoes produce
more CO² than all the world's factories, cars
and planes put together. More comes from animals and bacteria. An even
larger source is dying vegetation. But the biggest source of CO2,
by far, is the oceans.
Professor Carl Wunsch from the Department of Oceanography at MIT
explains "The ocean is the major reservoir into which carbon dioxide
goes when it comes out of the atmosphere and from which it is readmitted
to the atmosphere. When the surface if the ocean is heated it emits
carbon dioxide, and similarly when it cools it will absorb carbon
dioxide".
So why is there a time lag of several hundred years between a
temperature change and CO² being
released or absorbed by the oceans? The oceans are so big and so deep,
this is how long it takes for them to change to match the atmospheric
temperature.
Solar Physicist Dr Piers Corbyn tells us "The origin of our
solar techniques of weather forecasting come from the study of sun-spots
and the desire to predict these".
Sun-spots, we now know, are intense magnetic fields which appear at
times of higher solar activity. For many hundreds of years, long before
this was properly understood, astronomers would count the number of
sun-spots in the belief that more spots heralded warmer weather.
In 1893, the British astronomer Edward Maunder observed that during
The Little Ice-age there were barely any spots visible on the sun.
Appearance of sun-spots
In 1991, senior scientists at the Danish Meteorological Institute
decided to compile a record of sun-spots in the 20th century and compare
it with the temperature record. What they found was an incredibly close
correlation between what the sun was doing and changes in temperature on
Earth. To test this further, Professor Friis-Christensen and his
colleagues examined 400 years of astronomical records and found the same
correlation between solar activity and Earth temperatures.
Obviously, the sun affects us directly with the heat it radiates. It
is also believed that it affects us indirectly. Clouds are formed when
cosmic rays, from far out in the Universe, enter the atmosphere and meet
water vapour rising from the planet surface to form waters droplets.
When the solar wind is strong, from increased activity on the sun's
surface, fewer cosmic rays get through and fewer clouds are formed.
The climate is being controlled by clouds, clouds are controlled by
cosmic rays and cosmic rays are controlled by the sun. The sun drives
our climate, carbon dioxide is irrelevant.
Doom-laden predictions about climate change are not new. In 1974, the
BBC warned us of an impending disaster, which might seem strangely
familiar, only this time they were predicting an imminent ice-age.
