Greenhouse effect is a myth, say scientists

Research said to prove that greenhouse gases
cause climate change has been condemned as a sham by scientists.
A United Nations report earlier this year said humans are very
likely to be to blame for global warming and there is "virtually
no doubt" it is linked to man's use of fossil fuels.
But other climate experts say there is little scientific evidence
to support the theory.
In fact global warming could be caused by increased solar activity
such as a massive eruption.
Their argument will be outlined on Channel 4 this Thursday
in a programme called The Great Global Warming Swindle raising
major questions about some of the evidence used for global warming.
Ice core samples from Antarctica have been used as proof of
how warming over the centuries has been accompanied by raised
CO2 levels.
But Professor Ian Clark, an expert in palaeoclimatology from
the University of Ottawa, claims that warmer periods of the
Earth's history came around 800 years before rises in carbon
dioxide levels.
The programme also highlights how, after the Second World War,
there was a huge surge in carbon dioxide emissions, yet global
temperatures fell for four decades after 1940.
The UN report by the Intergovernmental Panel on Climate Change
was published in February. At the time it was promoted as being
backed by more than 2,000 of the world's leading scientists.
But Professor Paul Reiter, of the Pasteur Institute in Paris,
said it was a "sham" given that this list included the names
of scientists who disagreed with its findings.
Professor Reiter, an expert in malaria, said his name was removed
from an assessment only when he threatened legal action against
the panel.
"That is how they make it seem that all the top scientists
are agreed," he said. "It's not true."
Gary Calder, a former editor of New Scientist, claims clouds
and solar activity are the real reason behind climate change.
"The government's chief scientific adviser Sir David King is
supposed to be the representative of all that is good in British
science, so it is disturbing he and the government are ignoring
a raft of evidence against the greenhouse effect being the main
driver against climate change," he said.
Philip Stott, emeritus professor of biogeography at the School
of Oriental and African Studies in London, said climate change
is too complicated to be caused by just one factor, whether
CO2 or clouds.
He said: "The system is too complex to say exactly what the
effect of cutting back on CO2 production would be or indeed
of continuing to produce CO2.
"It is ridiculous to see politicians arguing over whether they
will allow the global temperature to rise by 2c or 3c."
The documentary is likely to spark fierce criticism from the
scientific establishment.
A spokesman for the Royal Society said yesterday: "We are not
saying carbon dioxide emissions are the only factor in climate
change and it is very important that debate keeps going.
"But, based on the situation at the moment, we have to do something
about CO2 emissions."
