Watch Penny Wong Interviewed on ABC's Lateline

For those of us craving a clear, concise and logical explanation of what on earth the ETS is all about the occasion was richly entertaining but not alas enlightening.

Despite being asked repeatedly about the ETS’ cost impact on families – working, non-working and bone idle – not a single figure passed Penny’s lips. She claimed that extensive modelling was released in 2008. That was apparently too long ago for her to remember the numbers it contained but for those who are still interested there is always the chance of coming across it in a library or a loo.

Tony’s questions about the ETS cost hikes to families in the event of an emissions reduction target higher than five percent were met buy a dogged refusal even to countenance such an abstruse notion.

The kindest possible assessment of Penny’s interview is that it added diddly squat to viewers’ storehouse of ETS knowledge and may even have eroded it slightly. But wait. On the subject of Tony Abbott’s Emissions Reduction Fund Penny demonstrated encyclopaedic knowledge. She came armed with sheafs of documents claimed to contain irrefutable evidence that Tony’s ERF was a non-starter and would cost squillions more than the ETS whatever that costs.

This was like a football coach explaining that his team’s tactics were based on a 2008 plan which he couldn’t remember but that doesn’t matter because the opposition are so hopeless.

Kevin has admitted that his government must improve their communications about the ETS. The question is did he forget to tell Penny, did she ignore him or was this, heaven help us, what she considered to be an improved communication.

Probably as a result of urgings by the spin doctors to soften her image Penny has developed a sudden synthetic smile for television interviews. When Tony asked questions she considered tiresome, embarrassing or downright dangerous she flashed on the smile to mask a face almost certainly contorted with rage and betraying an irresistible urge to choke the living shit out of him. Luckily he was in a studio hundreds of kilometres away.

The interview raised the issue of who can we possibly believe on matters of climate change.

Polar bears are the living proof we can’t trust Al Gore. Penny is about as helpful as a call centre operator in Bangalore and Kevin’s still got a Copenhagen complex. Climate change scientists have slipped up on the Himalayan glaciers and following his recent conversion it is too soon to expect anything sensible from Tony Abbott.

No wonder Lord Monckton is commanding so much attention. His is the only clear message on climate change; lie back for ten years, let it happen and then take stock. Even if he isn’t right its refreshing to hear a convenient truth amongst the deluge of inconvenient, incomprehensible and disingenuous approximations.

With all due respect to Kevin, climate change is not the greatest moral challenge of our generation. It is rather persuading politicians, scientists and opinion leaders to come clean about it.
