ok, i jumped the gun to early, the doco looks good and referenced, my mind is open to opinions and facts, I'm no fundy. I am an environmentalist and yeh, the global warming/greenhouse gas fear has been a great cause for change. The opposition leader here in Oz has just announced policy for a national green car. All the same, the truth is the highest value and I'm all for the truth. Thanks to the OP for the link, been wanting to watch it since I heard about it. We need both scientific camps to go head to head, we need clarity of info.
