Green politicians have lost their ability to deliver sustainable thoughts.

I'm no scientist so I get a bit lost in the details, but it certainly seems that the planet is going through some sort of change and that we are not well placed to cope. Our carbon sinks are being cut down (like the Amazon) or worse, burnt down as in the Indonesian fires, Australian fires and frequent Californian fires. If CO2 is part of the problem it is feasible that a very small contribution from human activity could push us over the brink. Anyone who has used balance scales knows that a tiny imbalance can have a big effect. Even if we and the planet are churning out the same old amount of carbon, that same amount can no longer be reabsorbed as it used to. Global dimming could be masking the true heating effect of our current atmospheric mix. CO2 is acidifying the oceans, no matter where it comes from, which has huge implications for the future of coral reefs, shell forming creatures including krill (ie the ocean food chain) and therefore huge implications for us humans. Which of course brings us to our good friend the population elephant, sitting quietly in the corner of the room.

No mate, you just went MIA in the big-picture stuff - never mind the details. We'll send out a search party, somewhere to that "CO2-acidified ocean" stuff..

OLO really has become "denialist central" as far as climate change goes, hasn't it?

Yep. CJ's spot on. AGW/CC/Gaia worshippers are still in chronic denial about:

1) the planet's cooling temperatures;
2) the refusal to allow or even recognize scientific dissent, instead lying about "the consensus", "nobody seriously disputes...", etc., and
3) bankers' and monopolist privatizers' dominance, coercion and control around said "consensus" and its prospective ETS/CRTS/fart tax bubble.

Kenny,

Your attack on Plimer's character and motivations doesn't seem very well thought through. If he was in it solely for the money, he'd write a book called "Doomed!", "50 Ways to Save the Planet", or "How to Survive The Coming Global Warming", which would walk off the shelves. A 500 page tome with over 2000 references isn't the kind of book that generally cracks the bestseller list. Besides, according to Protagoras he's making enough money from his corrupt mining interests.

Of course, if Heaven and Earth wasn't going into its fourth printing with 20000+ sales, you'd accuse him of being a fringe scientist with no relevance. It's damned if you do, damned if you don't when "the mob" rely so heavily on ad hom attacks. Perhaps the people buying this book are independent thinkers who are interested to read what a Professor of Earth Sciences at Melbourne Uni has to say on the subject.

But I've bought into your diversion, which is where debate is usually led by the cynical conspiracy mob, rather than actually reading and discussing the substance.
