Appearing before the emissions trading scheme review select committee yesterday, he said climate science dealt with a very complex system.
Some things were well established, in other areas there were competing explanations, and in yet others only speculation.
"The fact that there are speculative components does not eliminate the fact that there are well-established bits," Schneider said.
"System science works on the preponderance of evidence and you have to make risk management assessments."
In the well-established basket are the so-called "hockey stick" graphs showing steep rises in levels of carbon dioxide, methane and nitrous oxide since the dawn of the industrial era.
Is the above line an actual quote from "expert" Schneider or Brian Fallow's humble opinion. The absence of exclamation marks makes it very unclear.
Either way, along with some dozy TV1 "news" reporter on a beach with a tape measure, we are being fed BS.
It is my understanding that the hockey stick graph is in the not-so-well established basket. Or more likely the fear mongering basket.
