David, thank you for fronting those senators. Oz remains so mired in stupid faux-debate about the scientific realities that the frustrations of actually discussing the policy ramifications induce a state of permanent facepalm.
I am a short-term pessimist, long-term optimist.
I think that describes me as well. I was the author of the quote Jim referred to and I think it would help to provide a fuller version of the comment:
By the 2050's you might start to see significant reductions in Australia's emissions. It would be sooner, but our Tweedledum-Tweedledummer choices of government will evade imposing on emitters a price anywhere near the actual externalised costs they are currently getting away with. I would guess in the 2050's, the transition will be relatively swift (due to the economic factors rather than environmental or political).
I agree generally with where you are at, but I think it will take a bit longer. My time frame is based on what I see as likely allowing minimal financial impost. When existing plants are "lifed" over a 20 to 40 year timeframe, economics will dictate increased use of renewables. I do not see Australia being an early adopter of GenIV nuclear technology, so it would not happen quickly even if we went that path (and who is prepared to spend the political capital to convince the Australian public its necessary?). One of our current options favours charging about $3.50 per ton of carbon when the price is floated in a few years, and the other favours diverting public revenue to spare the polluters having to pay to clean up their own mess. No Australian party is remotely credible on this issue. Maybe we should start one?
I found it interesting that your comments about the consequences of necessary actions (such as inevitable recession) were taken by the senators as advocacy of those consequences. Its a bit like a patient thinking their oncologist has just told them that making them nauseous and bald is supposed to help their cancer...mind you an old-unreconstructed-shop-steward like Doug Cameron is hardly going to run at anything that will cost the jobs of "his" workers, and Chairman Smug MBA, is wedded to an Friedmanian model of a perfect market and the infinite growth miracle. Even Christine Milne was more interested in fishing for a soundbite about denial that to face the fact that someone - like, say, Christine Milne - needs to remind people who accept the science that if they don't do anything about that then their acceptance is of no practical use.
BTW, my local Green senator does catch the bus - I see her often on my daily commute. It's not that politicians actually leading would convince anyone to review their own consumption practices, but that attitude of "as long as they do not, why should I" prevents any further reflection. Just like people who say Australia shouln't cut its emissions until China does...Baffling.
