When was the CO2 levels been 1000 times current levels, with evidence? A book isn't science.

Probably when there were anerobic life only or very early in the earth's history. Sort of unsubstantiated figure that you could throw into a debate and walk away from before someone gets the chance to ask you "did it support multi-cellular aerobic life"?
I face-palmed when the poster that continually rants on about fraud and bad science quoted the individual (Ian Pilmer) in question.
Monbiot (amongst others) completely thrashed his book "Heaven and Earth"
Quote:
Seldom has a book been more cleanly murdered by scientists than Ian Plimer's Ian Plimer's Heaven and Earth, which purports to show that manmade climate change is nonsense. Since its publication in Australia it has been ridiculed for a hilarious series of schoolboy errors, and its fudging and manipulation of the data. Here is what the reviews have said.
Professor Kurt Lambeck, earth scientist and President of the Australian Academy of Science:"If this had been written by an honours student, I would have failed it with the comment: You have obviously trawled through a lot of material but the critical analysis is missing. Supporting arguments and unsupported arguments in the literature are not distinguished or properly referenced, and you have left the impression that you have not developed an understanding of the processes involved. Rewrite!"

Plimer then challenged Monbiot to a debate, Monbiot accepted, Plimer stood down.
Monbiot then published a list of questions for him to answer re. some of his claims (sea ice expanded, using the same graphs as the great global warming swindle (which were later retracted), and heard nothing since.
and this particular oft touted gem.
Quote:
10. You state that:"Volcanoes produce more CO2 than the world's cars and industries combined." (p413)
This is similar to the claim in The Great Global Warming Swindle, whose narrator maintained that:"Volcanoes produce more CO2 each year than all the factories and cars and planes and other sources of man-made carbon dioxide put together."
But you do not provide a source for it.
This is what the US Geological Survey says:"Human activities release more than 130 times the amount of CO2 emitted by volcanoes".
a. Please provide a reference for your claim.
b. How do you explain the discrepancy between this claim and the published data?

If this debate is going to be about honesty, transparency and fraud then I think it only fair to point out the credentials of this individual to comment on the subject. Even his friends can't defend him.

Reviewing this book has been an unpleasant experience for me. I have been a friendly colleague of Plimer's for 25 years or more. I admired his support for innovative geological research during his early career as a mineral explorer in industry. I cheered him on when he took on the so-called creation scientists and their bogus nonsense, a crusade that cost him dearly in the end. I have enjoyed his always lively and entertaining lectures. But this time, in my opinion, he has done a disservice to science and to the community at large.

Nonetheless he is Exhibit Z for an oft cited (as witnessed here once) mouthpiece for the argument against AGW when in reality when his inaccuracies (being kind) are questioned he disappears. Meanwhile people latch onto his every word. Strange ......
Some dude even wrote 46 pages checking his claims
Who'd thought going after the individual behind the statement could be so much fun?
