The Australian Academy of Science maintains the view that recent global
warming is caused by unprecedented CO2 levels in the atmosphere, despite
claims made in a recent documentary.


The pseudo-documentary 'The great global warming swindle', shown on ABC
television on 12 July, poses a simplistic question: Is the Earth's
climate driven by CO2 or the sun? 


The answer is, both. It's true: the sun does have an impact on the
Earth's climate, but this is on a 10,000 year cycle. The sun and the
moon control long-term shifts in the orientation of the Earth's axis.
Variations in the sun's energy output on shorter time scales,
particularly for recent decades, cannot explain recent warming. 


Solar effects are small compared to the unprecedented human-induced
changes to CO2 levels in the atmosphere. 


President of the Academy of Science, Professor Kurt Lambeck said: 'Those
who deny human-induced global warming are in the same camp as those that
deny smoking causes lung cancer and that CFCs deplete the ozone layer.


'There is too much at stake to be side-tracked by discredited theories
and out-of-date data.' 


The overwhelming view of the scientific community engaged in climate
research is that human-induced CO2 is having a powerful and potentially
irreversible impact on the planet's climate.


A scientific rebuttal of the so-called swindle is available on the
Academy's website at www.science.org.au/reports/index.htm
