The Government has its own politicians and a vast supportive bureaucracy in Government Departments and the CSIRO pressing the case. It has also established a series of "independent" bodies to review the data, then explain that global warming is taking place and to promote its favoured carbon tax.
The latest is the Climate Commission headed by Tim Flannery. This has a budget of $5.6 million and comprises five members who can be relied upon, supported by nine science advisers.
We already have Garnaut's Review of the 2008 Garnaut Review, staffed by personnel seconded from the Department of Climate Change and elsewhere who are committed to the greenhouse cause.
Then there are the expert advisors to Parliament's "multi party committee on climate change" and government subsidised bodies like the Grattan Institute.
The Government's generosity with taxpayers' money means we are being bombarded by material from three greenhouse related directions.
First we are told that thousands of scientists all agree that man-made warming, now renamed climate change, is taking place and that recent hurricanes and, counter-intuitively, cold spells, actually substantiate this. Evidence that the weather anomalies have always been with us are dismissed. So is the fact that the drought has broken and that our rivers are no longer drying and that the data showing the world's climate unexpectedly and inconveniently has not warmed for 15 years.
There are many scientists with views on the debate but in fact few of these are credentialed in the key area of climate physics. Indeed climate change skeptic Richard Lindzen, the world's foremost atmospheric physicist, points out that only a few hundred people in the world have the qualifications appropriate to speak with authority.
Secondly, Australia is depicted as standing alone against a tide of international action to tax carbon. Unstated will be the fact that we already wastefully ensure more electricity than average is produced from politically correct non-carbon sources like wind. Wind produces two per cent of our electricity, a larger share than the US, Japan, China and the UK. Moreover, the US states, like the Obama Administration, are reneging on previous commitments to reducing carbon emissions, a process that has now commenced in Europe where Holland, Spain and the UK are leading the retreat.
