Star witness

homer.jpgThe Environment Court is currently hearing the appeal against consents granted for Meridian Energy‘s Project Hayes windfarm in Central Otago — and has been forced to sit through some evidential nonsense from climate cranks. Auckland property developer Roch Sullivan joined the appeal last year, and announced that he intended to bring some leading climate cranks to give evidence. Last Friday it was Chris de Freitas’ turn and he did our plucky little NZ cranks collective proud, as the Otago Daily Times reports under the headline “Professor denies greenhouse effect“:

Prof de Freitas, of the University of Auckland, said there was no evidence to suggest carbon dioxide was the major driver of climate change. “Climate is not responding to greenhouse gases in the way we thought it might. If increasing carbon dioxide is in fact increasing climate change, its impact is smaller than natural variation. People are being misled by people making money out of this,” Prof de Freitas said.

He said mild warming of the climate was beneficial, especially in a country such as New Zealand, which had a prominent agricultural industry.

“One could argue that carbon dioxide is quite beneficial. There may be benefits of wind farming that I may not be aware of, but there is no data to show benefits in terms of mitigating potential dangerous changes in climate by offsetting carbon dioxide,” he said.

No evidence to suggest carbon dioxide was the major driver of climate change? I think the good professor is somewhat understating the case — at the very least, being economical with the truth. How a respected academic can ignore 150 years worth of physics and four successive IPPC reports is a matter that might be of interest to psychologists (perhaps even his head of department), but it gets better.

Prof de Freitas admitted there was debate about climate change, when questioned during cross-examination by Central Otago District Council lawyer Graeme Todd. “The debate centres on causes. There is a possibility climate change could be impacted by human beings, but it is not a significant impact,” he said.

In response to a question by commissioner Alex Sutherland, Prof de Freitas said the jury was out on climate change, and preemptive action could be dangerous. “There’s no basis for alarm. We might be shooting ourselves in the foot if we act on what turns out to be a bubble-less pot,” he said.

The jury is still out, not on the reality of climate change, but on whether so misrepresenting the evidence amounts to a contempt of court. The duties of an expert witness before the Environment Court include:

5.2 Duty to the Court

5.2.1 An expert witness has an overriding duty to assist the Court impartially on relevant matters within the expert’s area of expertise.

5.2.2 An expert witness is not an advocate for the party who engages the witness.

Since de Freitas’ areas of expertise include tourism, climate in caves, and suitable clothing for Canadian winters, it appears he is somewhat overstating his expertise in daring to advise the court in those terms. I do hope the judge is lenient, for his sake. Or perhaps de Freitas simply wishes to be acknowledged as an inexpert witness…

Games without frontiers

ClimCity.jpg

Jeux sans frontières realised in Clim’ City, an interesting learning game with obvious antecedents from Bordeaux’s Cap Sciences centre: reorganise the energy sources and economy of this French city and its surroundings – from ski field to beach resort – to reduce greenhouse gas emissions without crippling the economy. According to the Technology Review story, it’s not easy to “win”, but if you don’t speak at least a little French it’s impossible… 😉

I hope one of the English-speaking science centres does a translation: I can see this being a great teaching tool. Now, do I create an association des citoyennes or go straight to shifting the centrale thermique to burning biomass, but that means expanding the forestry sector, and perhaps I should make sure that the forests are protected against forest fires, what with the warming in the pipeline…

Coppiced willow farming here

This column appeared in the Waikato Times in August 2008.  I have altered some of the wording to update it for this Hot Topic post.

The change to renewable energy sources can seem daunting. Those with stakes in fossil fuels are often negative, claiming change will be too expensive, too difficult, or not yet necessary. Cries of economic doom have greeted even the modest emissions trading scheme which may or may not be carried forward by the new government.

It was encouraging therefore to read a few months ago of the plans of renewable energy company Pure Power to launch a variety of shrubby willow as a biofuel crop in New Zealand. Biofuels which use food crops or destroy rainforests have had a justifiably bad press. But not all biofuel crops are equal. Coppiced woody plants like the willow Pure Power plans to use have a very good ratio of energy output to the energy put into converting them; they can be grown on poorer soils not used for food production; they require little fertiliser or irrigation; using new technologies they will produce not only biofuel but also a range of products for making paints, resins, adhesives and bioplastics.  Pure Power will have nursery stock ready for planting this year and hopes for a rapid expansion of planting in subsequent years.

Solar wind sculptures

windturbine.gif Time to nail my colours to the tall thing. Submissions on Mainpower’s Mt Cass windfarm consent application close on August 1st, and I’m running out of time to get one in (being busy, and all that). The opposition is getting itself organised, with a web site to co-ordinate dissenters, including a very nice gallery of pictures. I know (and love) this sort of landscape. I live in it.

I have some sympathy for the guys running the site, because I organised/designed/published the “Dump The Dump” web site for opponents of the Kate Valley landfill scheme. We lost, despite generating a record number of opposing submissions. I even did a presentation to the consent hearing, and got a mention in the final judgement. I still think we could have defeated the dump if we’d taken the issue to Christchurch, rather than kept it local and “played by the rules”…

All together now

tintinsnowy.jpg It’s getting hectic down here in the Waipara bunker: articles to write, truffles to harvest – stuff is piling up, not least in a multitude of tabs in my web browser, items set aside as possible subjects for posts here. So here’s one of my infrequent omnibus posts to give me some room to move around the web…
