Global cooling?

Okay, so what’s the truth?

RESEARCH said to prove that greenhouse gases cause climate change has been condemned as a sham by UK scientists.

Are you hearing about this anywhere?

A recent United Nations report said humans were very likely to blame for global warming and there was “virtually no doubt” it was linked to man’s use of fossil fuels.

We’ve sure heard a lot about that.

But sceptical climate experts say there is little scientific evidence to support the theory.

In fact, they claim global warming could be caused by increased solar activity.

Their argument will be outlined on Britain’s Channel 4 this week in a program called The Great Global Warming Swindle.

It raises major questions about some of the evidence used for global warming.

Hasn’t this major, award winning thesis been held up to peer review and scrutiny?

Ice core samples from Antarctica have been used as proof of how warming over the centuries has been accompanied by raised carbon dioxide levels.

But University of Ottawa professor of paleoclimatology Ian Clark claims that warmer periods of the Earth’s history came around 800 years before rises in carbon dioxide levels.

The program also highlights how, after World War II, there was a huge surge in carbon dioxide emissions, yet global temperatures fell.

The UN report by the Intergovernmental Panel on Climate Change was published in February.

That got wide coverage. Will ‘The Great Global Warming Swindle’ get coverage beyond Britain’s Channel 4?
