Hi all...

The ABC have the audio for the "Big Ideas Symposium" held last weekend in
Adelaide on line for downloading

There were 4 speakers - including James Lovelock and Peter Cullen

I would strongly recommend you do so and listen to the issue from a
slightly different perspective...
the Australian one - where despite the best attempts of the PM Howard, the
issue is definitely in the public eye.
