Sceptics' corner

Some Australian politicians and ordinary people in our community are still doubtful about climate change. While some deny that the planet is warming, or accept the warming but deny the link to greenhouse gases, many are just doubtful and confused: they don't really know what to think.

This is a serious problem. It would be a huge relief to discover that the scientists have got it all wrong. But the science of global warming is now quite clear and we urgently need to respond. Doubt and confusion only sap our will to act, which is exactly what the powerful fossil fuel lobby wants.

If you find sceptics' arguments persuasive, but still have an open mind, here are a number of resources to help clear up the confusion.

however you're sure the scientists are wrong and climate change is definitely not a problem, then please submit your paper here and await your Nobel Prize. Or seek help.

Rebutting Christopher Monckton

Christopher Monckton, Third Viscount of Brenchley attracted a great deal of media attention for his lecture tour in Australia in 2010. But Monckton’s presentation has been rebutted in detail by Professor John Abraham of the University of St Thomas. Watch the video >>

A response to Leon Ashby

Leon Ashby's Climate Sceptics Party presentation "Why an Emissions Trading Scheme (ETS) is not necessary" presents a range of evidence that appears to support his view that rising CO2 is not a problem and could even be a good thing.

Having searched in vain for an online investigation of Ashby’s claims, I compiled this critique.

Ian Plimer's Heaven and Earth

If you've read or heard about this book and think it deserves some credence, consider what others have said about it.

Prof Ian Enting from University of Melbourne has provided a detailed, point-by-point critique (46-page PDF)

Wikipedia has a good summary highlighting the difference between the book's reception in the media and its reviews by scientists. Here is a selection of the latter:
  • Prof David Karoly on ABC Science Show: Are Plimer's claims justified and based on science? ...The book is impressive and possibly interesting, but very disappointing. ...It's disappointing because a senior professor should not have produced such a book with so many errors, so many internal inconsistencies, and with no sources for its graphs.
  • Prof Barry Brook: I’ve been critical of Ian’s views before ...Ian’s assertions about man’s role in climate change were naive, reflected a poor understanding of climate science, and relied on recycled and distorted arguments that had been repeatedly refuted. ...[A]fter reading [Heaven and Earth], I find that nothing has fundamentally changed.
  • Tim Lambert: Ian Plimer's approach to climate science in Heaven Earth is unscientific. ...He accepts any factoid that supports his conclusion and rejects any evidence that contradicts his conclusion.

Conspiracies and the IPCC

Some of Australia's leading politicians such as Tony Abbott and Senator Nick Minchin have variously dismissed the Intergovernmental Panel on Climate Change as "alarmist" or fuelling a left-wing conspiracy to "de-industrialise" modern society. ...So is the IPCC really that kooky? Read on >>

And what about the Nongovernmental International Panel on Climate Change?
These 23 individuals from 15 countries, including a handful of scientists, disagree. Led by physicist S. Fred Singer—best known for his denial of the dangers of secondhand smoke—they argue the reverse: "Natural causes are very likely to be the dominant cause" of climate change.

Hacked emails!

  • Nature: "UEA scientists sharply criticized ...papers that question the uniqueness of recent global warming ...and vowed to keep at least the first paper out of the ...IPCC. Whatever the e-mail authors may have said to one another in (supposed) privacy, however, what matters is how they acted. And the fact is that, in the end, neither they nor the IPCC suppressed anything: when the assessment report was published in 2007 it referenced and discussed both papers." Read more >>
