"The Great Global Warming Swindle"

" The prevailing global-warming view is that man-made emissions of
carbon dioxide are largely responsible. This film, featuring leading
academics ..... questions the science behind the accepted reasons for
global warming and argues that other explanations - including the
effect of the sun's radiation on the atmosphere - are not being
properly aired."

Thanks for the advance notice, Martin. I shall make a note to ensure
I do not miss it.
I shall wait until I have seen it before passing judgement, rather
than criticise it in advance!
I would however not expect them to present 'both sides of the
argument' as the point of the programme seems to be to present the
'other side' (climate change) which is usually happily ignored by AGW
broadcasts.

I don't think they are denying climate change but saying that man-made CO2
is not the main cause. That is fine with me as long as the facts they use to
support their case acuially represent the true position.

I get annoyed when, for example, someone staes that becasue glacier X is
getting bigger the climate is not warming up and toatlly ignoring the fact
that galciers A to W inclusive have shrunk. This is an extreme example but
if they can make their case without resorting to such tactics it will be
far more credible.

I assume that this is about the theory that solar activity modulates the
cosmic ray influx which then changes the rate of production of cloud
condensation nuclei which changes the amount of cloud cover which
changes the global temperature.

This was recently discussed on another newsgroup. The problem presented
(by a working climatologist) with this theory is that it doesn't predict
the observed chronological and geographical distribution of warming;
greenhouse warming is predicted to be greater at high latitudes, in
winter, and at night, which matches observations. This other theory
should predict that warming is greater during the day (because the
warming is due to a reduction in cloud cover).
