Professor Robert Manne gets his facts wrong again

In an opinion piece in the Anzac Day issue of the Australian, Professor Manne gets his facts wrong again. For some previous errors of truth by Manne see Paul Sheehan's excellent book "Among the Barbarians."

Some errors in his article:


• (Ian Plimer) describes the entire climate science community as "the forces of darkness"

Think about it, Robert. Is he calling himself a part of the "forces of darkness?" Are all the scientists that he refers to part of the "forces of darkness?" on the other hand, are you, Professor Manne (a non-scientist) part of the "Forces of darkness?"


• The work of these scientists has been summarised in four cautious reports of the Intergovernmental Panel on Climate Change. In the most recent, the IPCC argued that the evidence for human causation of climate change was unequivocal.

Well, not quite unequivocal, Professor. They actually said "very high conīŦdence" which represents at least a 9 out of 10 chance
of being correct. Mind you in the same report they also said "Warming of the climate system is unequivocal." Warming is a bit different to man-made or as you say "human causation" warming.
These IPCC "scientists" also said in their AR4: "Carbon dioxide is the most important anthropogenic greenhouse gas." That is correct, if they pay no regard to water vapour. Science tells us that the most important greenhouse gases are:
water vapor, which contributes 36–72%
carbon dioxide, which contributes 9–26%
methane, which contributes 4–9%
ozone, which contributes 3–7%


• Many regard the work of the tens of thousands of climate change scientists as fraudulent and the IPCC as a sinister and vast international conspiracy.

Hey, Prof, you got that right. If you read the fourth Assessment report, and the science in the reports behind the Summary for Policymakers, you will find that the Summary for Policymakers is not supported by the science. If you call that a conspiracy, then so-be-it. As to the "tens of thousands of climate change scientists" - how many of them are independant of Government Grants?

• In the other camp are a few dozen scientists.

Wrong again - As an example, Professor, just google "petitionproject.org" more than 30,000 scientists, look also at the International Climate Science Coalition, The Australian Climate Science Coalition, The New Zealand Climate Science Coalition.

How can one learned Professor get it so wrong, so often?
