In defence of banning the bulb

I see Canterbury University economist Eric Crampton politely disagrees with my post on the failure to ban incandescent light bulbs. I’d like to comment on a couple of the points he raises. The first concerns the non-priced carbon embodied in the production and distribution of fluorescent and LED bulbs, and the possibility that it may be so large as to negate the advantages of lower carbon emissions during the lifetime of the bulbs.

Crampton admitted he had no clue, but assumed that the more complex efficient bulbs would have a higher carbon footprint in their manufacture than the incandescents. However, he allowed that the longer life of the efficient bulbs probably gave them the overall advantage. I had no clue either, though I’m familiar with the need to take embedded carbon into account when making comparisons and guess I assumed that was not something that had been overlooked in the advocacy of CFLs and LEDs. However I had a look to see what I could find, and came across this assessment of CFLs from a writer initially inclined to be sceptical about them, and this report on LEDs. It doesn’t look to be an issue.

Cranks lose court case against NZ temperature record, NIWA awarded costs

The attempt by NZ’s merry little band of climate cranks to have the NZ temperature record declared invalid has ended in ignominious defeat. In his ruling [PDF], handed down today, Justice Venning finds:

The plaintiff does not succeed on any of its challenges to the three decisions of NIWA in issue. The application for judicial review is dismissed and judgment entered for the defendant. [and] The defendant is entitled to costs.

It will be interesting to see whether the NZ Climate Science Education Trust, which was established purely to bring this action, is able to stump up to cover NIWA’s costs. If it doesn’t, the NZ taxpayer will be left to pick up the bill for this absurd bit of political grandstanding by the Climate “Science” Coalition.

In his decision, Justive Venning makes a number of interesting points, noting in paragraph 48:

This Court should not seek to determine or resolve scientific questions demanding the evaluation of contentious expert opinion.

Embarrassingly for the CSET, the judge also finds that two of its “experts” were nothing of the sort, declaring large chunks of their “evidence” inadmissible. Here’s the judge on former journalist Terry Dunleavy [par 51]

Section 25 could only apply if Mr Dunleavy was an expert in the particular area of the science of meteorology and/or climate. He is not. He has no applicable qualifications. His interest in the area does not sufficiently qualify him as an expert. I also accept Mr Smith’s further point that Mr Dunleavy’s views are not capable of offering substantial help to this Court on the issue that it has to determine. To that extent I agree that substantial passages of Mr Dunleavy’s evidence are inadmissible.

And in par 53, referring to the CSET’s stats man:

Similar issues (as to the limited nature of his expertise), apply to the evidence of Mr Dedekind.

[54]… Mr Dedekind’s general expertise in basic statistical techniques does not extend to any particular specialised experience or qualifications in the specific field of applying statistical techniques in the field of climate science. To that extent, where Mr Dedekind purports to comment or give opinions as to NIWA’s application of statistical techniques in those fields, his evidence is of little assistance to the Court.

The judge also noted that the other expert witness relied on by the NZ CSET, Bob Carter, also made a number of mistakes in his evidence. Not a good look…

I did have to laugh out loud at one point (not something that often happens when reading a judgement), when reading the judge’s comments on the original NZ CSET submissions:

Both the original statement of claim and the first amended statement of claim were prolix.

One wonders who brought a shine to those words…

No doubt the crank spin machine will be hard at work to try to salvage something from this train wreck, but it’s hard to see how. Common sense has prevailed. Warming remains unequivocal, and can’t be ruled inadmissible — unlike the Coalition’s precious “experts”.

[Update: Leading Climate Scientists Welcome Judge’s Decision on Temperatures

Associate Professor James Renwick of Victoria University said he was pleased that the court had respected and reaffirmed the credibility of the scientific process. It was a strong message to those wanting to challenge widely-agreed scientific findings to do so honestly and openly in scientific forums.

…and…

… the case represents a massive waste of New Zealand tax payer’s funds. In defending the claim, NIWA has spent a huge amount (estimated at well over $100,000) and has diverted a number of its scientists away from their research. The country can ill afford to waste such an amount. “This misguided action of a small group adds confusion to a simple issue – the world is warming and future generations of New Zealanders will have to deal with the consequences” Dr Renwick said.

How fast shall we drive over the cliff? NZ’s ETS watered down (again)

How fast shall we drive over the cliffSimon Johnson looks at the Government’s amendments to the New Zealand Emissions Trading Scheme and concludes we are arguing about what gear to drive in as we speed towards the cliff. The Government has kindly given us the opportunity to make a submission about how fast fast we should go over the emissions cliff. Time to fasten your seatbelts.

Back in July, Tim Groser announced more watering-down of the New Zealand Emissions Trading Scheme (NZETS). About a week ago, on 23 August 2012, Groser introduced the amending legislation – the Climate Change Response (Emissions Trading and Other Matters) Amendment Bill. Consistent with previous emissions trading scheme legislation, the bill will be fully and rationally considered by Parliament’s Finance and Expenditure Select Committee in an insultingly short period of time – ten working days. The closing date for public submissions is Monday, 10 September 2012.

What does this ETS amending bill do?

Low hanging fruit and lost opportunity

I hope the New Zealand Government feels shamed by the news that incandescent light bulbs can no longer be sold in Europe. It could have been so here but following the 2008 election, proclaiming the sanctity of consumer choice, one of the early actions of the then Minister of Energy Gerry Brownlee was to reverse the Labour Government’s decision to phase out incandescent light bulbs. Almost equally dismaying was the statement by the Leader of the Opposition Phil Goff in 2009 that the Labour Government decision was a mistake in the first place. “We’d stopped listening to what people’s priorities were,” he said.

It’s hard to make any sense of the reversal of former Government policy on incandescents other than in the most cynical of political terms. It is in direct contradiction to any concern they express to tackle climate change. Lighting has been estimated to use nearly 20% of the world’s electricity and six years ago the International Energy Agency produced a report which concluded that a global switch to efficient lighting systems would trim the world’s electricity bill by nearly one-tenth. It is a low-hanging fruit in the reduction of carbon emissions. Even the US is to phase out incandescents.

Realism and risk: waiting for the bus

Climate Change Minister Tim Groser gave a substantial and intelligently argued speech recently to an informal meeting in Auckland of international climate negotiators met to discuss the  way forward to a new agreement in 2020. Groser makes the case for political realism in climate negotiation. He records his sense after attending a COP conference at Poznam a year before Copenhagen that the negotiation was not on track and that if more reality did not prevail Copenhagen might be a train wreck. It was, and he says that it was only some superb political leadership by the Mexican hosts at Cancun which got the UNFCCC process back on the tracks. “My conclusion is simple: negotiating scenarios which are developed without any political realism behind them cause great and unhelpful friction.”

The claim to political realism is always difficult to argue against, particularly with someone who has spent literally decades in difficult international trade negotiations, as Groser has. But those of us who aren’t negotiators or politicians can’t allow the question to be arbitrated only by those who are.
