I first read Ian Plimer’s book Heaven and Earth and interviewed him at length when it was published in 2009. In it he totally eviscerates, guts and fillets the AGW argument.


By way of background Plimer is Professor at the School of Earth Sciences at the University of Adelaide and Emeritus Professor of Earth Sciences at the University of Melbourne.


Thumbing through it again over the weekend I was reminded of this nugget. Something to keep in mind next time the CSIRO (or the BOM) is quoted as an authority.


Australia’s CSIRO runs this disclaimer with its climate projections:


“..The projections are based on results from computer models that involve simplification of real physical processes that are not fully understood. Accordingly, no responsibility will be accepted by CSIRO for the accuracy of the projections inferred from this brochure or for any person’s interpretations, deductions conclusions or actions in reliance on this information..”


That’s pretty clear I would have thought.


It’s an admission that they have “simplified a real process that they don’t fully understand in the first place” and accept no responsibility.

How would this stand up in a court as evidence from say, a forensic scientist? “..Your honour, I’m not sure and don’t really understand what’s going on here and I’ve simplified whatever it is, but don’t hold me to it. I could be wrong..”
