Carter is a known climate change skeptic, and perhaps his opinion interests the Howard government (appointed by the environment minister as a judge for an Aust govt prize for environmental journalism... yep, thats going to be a fair decision. sure.)...
Anyway, over to the climate science experts commenting on Gore's movie: Dr Penny Whetton, CSIRO: "... its scientific base is very sound..." Dr Michael Coughlan, head National climate centre, Bureau of Meteorology: " ... the science was generally solid..." Dr Kevin Hennessy, CSIRO climate impacts and risks group: "... its not quite that simple... but easily the best documentry..." Dr Graeme Pearman, former CSIRO director of atmospheric research: "didnt feel the presentation overstated based on current scientific knowledge" Dr David Jones, head climate analysis, National climate centre: "simplifications, but not outside the climate science knowledge envelope" Dr Barrie Pittock, former CSIRO climate impact group leader: "technically brilliant, remarkably accurate and up to date" Dr Kathy McInnes, CSIRO climate impacts and risk group: "surprised at how accurate the science was" and that was the full list published in the article.
Sounds like your prehistoric, idealogically driven palaeontologist friend Bob Carter should stick to breaking rocks and looking for dinosaurs.
