These posts are intended to share information and ideas about climate change and hence act as a roundtable. Again I do not want to spend time in comments rehashing whether human activity causes climate change.
This edition is mostly about the doings of our new government, prospective EU targets, a statement by religious leaders and a couple of items on health implications.
1. Greg Hunt’s role diminished
Whether or not Greg Hunt gets to go to the UNFCCC (UN Framework Convention on Climate Change) Conference of Parties (COP) in Warsaw from 11 to 22 November. Julie Bishop will henceforth be the lead negotiator in international climate talks.
The story in the AFR says Hunt has been “stripped of responsibility for global climate change negotiations”. He still gets to go and hang out at the talks. One might say that Australia’s representation has been upgraded. Suspicious minds might also think that Hunt couldn’t be trusted. He actually believes human activity causes global warming and might join the warmist urgers if not kept on a tight leash. Continue reading Climate clippings 84→
Last week on the 7.30 Report we were treated to a debate between Mark Butler, the climate change minister and his Opposition counterpart, Greg Hunt, that just did not work. Leigh Sales tried a hard-edged questioning style, but unfortunately did not come close to being familiar with the topic. So large parts of the LNP agenda were unaddressed, such as their dismantling of the institutional framework of the the Climate Commission, the Climate Change Authority, the incorporation of the Climate Department into the broader environment department and the dismantling of the Clean Energy Finance Corporation.
One issue canvassed was the sequestration of carbon in soil, which comprises a large part of the LNP’s mitigation strategy.
Mark Butler said the cost of such abatement was higher than previously thought, the potential for sequestration less and given the problems and uncertainties there “may be some opportunity to abate carbon pollution through soil carbon initiatives in the future, but it is grossly irresponsible to make it the centrepiece of a nationwide carbon pollution policy.”
Hunt dismissed those concerns, quoting the CSIRO but when he was pressed on whether he was talking about just soil carbon he said he meant the full range of green carbon initiatives – mallee and mulga revegetation, reforestation, avoided deforestation, soil carbon.
considering carbon storage on land as a means to ‘offset’ CO2 emissions from burning fossil fuels (an idea with wide currency) is scientifically flawed. The capacity of terrestrial ecosystems to store carbon is finite and the current sequestration potential primarily reflects depletion due to past land use. Avoiding emissions from land carbon stocks and refilling depleted stocks reduces atmospheric CO2 concentration, but the maximum amount of this reduction is equivalent to only a small fraction of potential fossil fuel emissions.
Yesterday The Climate Institute released a policy brief Coalition Climate Policy and the National Climate Interest which not to mince words is a complete crock, will increase emissions and ruin our reputation on climate matters in the world. The report, based on modelling by Sinclair Knight Merz-MMA and Monash University’s Centre of Policy Studies, was then declared by Greg Hunt to be “one of the silliest reports” he has ever seen prepared by “a clear partisan political organisation” which backs the ALP.
I’m not planning to do posts on the upcoming election apart from link posts if I see anything interesting and/or important. The post on the Murdoch’s intervention started out as a link post, but then I warmed to the task. While this space is open I’d like to explore a theme that came from a comment in reaction to the LNP ‘solution’ to the asylum seeker ‘problem’. I can’t find it now, but someone asked, “What have we become?”
The task is ambitious and I’m not academically equipped for it. I’m not speaking as a philosopher or a sociologist, just “someone who is trying to sort out his ideas”, so the results may be modest. Some of the posts may not appear to be directly on the topic, but I hope all will fit together in the long run.
Meanwhile I’ll try to keep some information flowing on climate change. Both these projects may be of more use than any contribution I can make to an election here in Oz. This time CC will be free flow rather than numbered items, to save time. I’ll use bold to identify the topics.
Arctic ice is losing its reflective sheen. We all know that ice reflects more incoming radiation from the sun than does open water. Now by analysing 30 years of satellite data scientists have found that albedo of the ice itself at the end of the summer is about 15% weaker today than it was 30 years ago.
The cause of the darkening is
partly due to thinning ice and the formation of open water fissures, and partly because in the warmer air, ponds of liquid water form on the surface of the ice. The shallow ponds on the ice can dramatically reduce reflectivity and increase the amount of solar radiation that the ice absorbs.
No-one should doubt the political potency of the climate change issue. Malcolm Turnbull’s demise came as a direct result of the bi-partisan agreement on an ETS negotiated between Ian Macfarlane and Penny Wong in 2009. In a three-way contest Joe Hockey was expected to win in a landslide, but he was eliminated in the first round of voting.
So what went wrong for Joe?
Yesterday, Mr Hockey was demanding a free vote to decide Coalition policy on climate change early next year, if he were to agree to take on the leadership.
That angered right-wing Liberal powerbrokers and prompted Mr Abbott to stay in the race for the top job.
It’s worth noting, as I did in the post Political thuggery and climate change that it was Abbott and Nick Minchin who told Turnbull he could only keep his job if he changed his stance on the CPRS. Also that Andrew Robb’s actions were described by Hockey as “the worst act of political treachery I have seen in twenty years of politics” and by Turnbull as “an act of almost inconceivable treachery and dishonesty”.
Rudd’s dumping of the CPRS in April 2010 was followed by a sharp fall in Rudd’s approval rating and party voting intentions. As I pointed out in Rudd, Gillard, the CPRS and public opinion the notion that Rudd was talked out of doing something about climate change by Gillard and Swan does not hold up. Rudd was dithering and unapproachable on the issue. When he called a meeting to discuss the issue his view was to leave an ETS until broad international agreement was achieved. Gillard wanted to wait for a return of bipartisanship with the LNP. Rudd decided to do it his way.
