Under Milk Woodford

I opened the farming page of the Waikato Times yesterday evening to see a prediction from Lincoln University agribusiness professor Keith Woodford that the government is likely to dump the methane component from the ETS. He was speaking to farmers at a Lincoln sheep and beef seminar. The articleis on Stuff’s website.

The basis for his prediction was political — in particular that the government couldn’t afford to lose the rural vote to ACT over climate change issues. However what struck me was not his political calculations but his claims about climate change.

 

There’s no consensus about the extent of climate change, he reportedly said, although some scientists claimed otherwise. He’s not saying there is no climate change, mark you, but pointing out that there’s a great deal of uncertainty “out there”. There’s an unfinished debate going on and anyone who says it is finished is either ignorant or untruthful.

In particular “some groups” have exaggerated fluctuating global temperatures, sea ice levels and the destruction of coral reefs. As for sea levels, they have been rising modestly for thousands of years, and earthquakes in New Zealand have tended to counterbalance that anyway.

Note the vagueness. Who are “some groups”? What is exaggerated about the rising trend in global temperatures which has been so painstakingly tracked? Are the sea ice extent graphs and measurements doctored? Is the concern of those who monitor coral reefs misplaced?  Is the measured increase in the rate of sea level rise imaginary? Is there no loss of mass from the Greenland and West Antarctic ice sheets?

Woodford seems to think all the specifics can be waved away with words like “exaggerated” or “uncertainty” or “unfinished debate”. And he accuses those who feel they must take the science seriously of ignorance and untruthfulness!

In terms of what we are hearing from farming circles these days Woodford’s statements are pretty standard fare. The New Zealand farming community appears to be foolishly cocooning itself in a protective shell of denial that climate change can possibly be as serious a threat as sober science says it is. Federated Farmers has been pointedly describing climate change as climate variability. They talk to one another and not surprisingly confirm their opinions by frequent repetition. But one might have hoped that the academics among them might inject some reality into the conversation. Evidently not at this university seminar from this professor.

What we do about climate change is one thing.  What we know about it is another. We may well be reluctant to take some actions, and there is certainly room for a variety of opinions as to how best to tackle the issue. The farming community may even have a case in relation to the ETS. But to bolster our preferences by claiming that the science is not settled enough to justify action is stupid and reckless. Where on earth does an academic like Woodford find the confidence to declare that there’s no consensus about the extent of climate change?  Does he have the faintest idea of the scientific literature?  Has he looked at any of the IPCC reports of what that literature reveals? Far from being marked by exaggeration the reports of climate scientists are on the whole marked by caution and caveat. That’s one of the reasons for taking seriously their generally agreed central findings.

The agribusiness professor no doubt has expertise in his own field. But he is only pretending to knowledge in climate science. He also confirms the prejudices of any farmers who likewise can’t be bothered to acquaint themselves with the reality of climate change. If farmers want to argue for exclusion from the ETS they should be doing so in full awareness of the climate crisis. Perhaps the trouble is that might undermine their case.

[Gareth adds: Keith Woodford is well-known for his role in promoting the health benefits of “A2” milk in his book Devil in the Milk: Illness, Health and Politics – A1 and A2 Milk. Perhaps less well-known is his 2006 paper Agriculture’s greenhouse emissions. How should they be calculated? in which he argued that NZ should use a 500-year timeline for calculating the global warming potential of methane in order to minimise its relevance to our emissions reduction activities. Woodford’s big idea has gained little traction, perhaps because it is impractical nonsense…]

Something for the weekend

Lazy blogging. Just links to a few things I think you might find interesting to read (and a performance to enjoy) while I get some work done. First up: Swiss Re, the giant reinsurance company, has published a handy new report called Climate sceptic arguments and their scientific background (pdf), written by Swiss scientist Urs Neu for ProClim. It deals with common sceptic arguments under three headings — global warming, forcing factors and carbon dioxide. Everything’s referenced back to the literature, the graphics are good, and if you thought my recent thoughts on rainfall extremes were mere speculation, you might find section A6 interesting.. 😉 (Hat tip to Mr Rabett).

Twas the night before… the ETS

Tomorrow morning, a large chunk of New Zealand’s much debated Emissions Trading Scheme comes into effect. Forestry’s already been in it for two years, but July 1st is the day that the liquid fuels and electricity generation sectors start to have to account for their emissions, and it’s the first day that consumers might see a change in fuel and electricity prices that can be blamed on the ETS. Last week’s National Business Review had a pretty good overview of the state of play here. The scheme has also come in for some robust criticism in a new book, The Carbon Challenge, by Sustainability Council executive director Simon Terry and VUW economist Geoff Bertram (of which more in another post soon, I hope).

Federated Farmers have been out protesting in force — even though agriculture gets a free pass until 2015, and then gets 90% of its emissions “grandfathered” (effectively free). A few weeks ago Farmers Weekly editor Tim Fulton popped in for a cuppa and interviewed me about my views on climate change, agriculture and the ETS for an article that appeared a couple of weeks ago. Most of what I said won’t be news to Hot Topic readers, but I thought it worth passing on my thoughts on agriculture and the ETS to a wider audience:

Electric cars take over

I recently watched the video of a TED talk by Shai Agassi. It dates from a year ago. I’m late catching up. But there may well be other readers who haven’t caught up with him either, so I’ll report my experience. He jumps straight to the point in his opening sentence: “So how would you run a whole country without oil?”

Agassi doesn’t intend his question to be hypothetical or far off. He’s talking about the near future.  And he considers the answer lies in electricity, preferably renewable, as a fuel for vehicles. Not a few vehicles, but 99% of them.  And cars as good as any that we have today, preferably more convenient and affordable. There’s no need to wait for further technological development. We have all we need already.

You can listen to his talk below. He sets out a compelling case, and an optimistic one. He is founder and CEO of Better Place, a company that works with governments, businesses and utility companies to accelerate the transition to sustainable transportation. Their website repays attention.  I’ll extract a few items from it here.

Electricity-powered transportation fits very well with the development of renewable energy sources.  Better Place accepts fully the imperative to stop the burning of fossil fuels.:

The economics of renewables create an extraordinary opportunity for transportation.  But the economics of transportation also create an extraordinary opportunity for renewables.

First, an electric vehicle (EV) system can take advantage of underutilized electricity, reducing oil consumption and providing resources for renewable development provided the EV system is complemented with a “smart grid” that optimally manages the flow of available electricity. Second, EVs can alleviate the problems of intermittency, unpredictability and off-peak generation that have hindered the progress of renewable energy in the past. Third, because EVs offer energy efficiency up to three times greater than that of gasoline-powered vehicles, EVs reduce the overall burden on energy resources.

The transition is already under way:

The electric car is becoming inevitable.  Nearly every major automaker has an active program to develop and introduce EVs, ultimately providing the consumer a broad range of options.  Better Place is currently working with the Renault-Nissan Alliance, which will be among the first to introduce EVs, and is also in discussion with major auto manufacturers around the world.

These electric vehicles will be distinctive in more respects than their zero tailpipe emissions.  EVs inherently provide instant torque, delivering smooth, seamless acceleration.  EVs also offer ultra-quiet operation.  And since these cars typically have half the moving parts of their gas combustion engine counterparts,  lower maintenance costs are expected.  All this means that in the coming decade, EVs will be at the center of mainstream personal transportation. (my italics)

The lithium-ion batteries are adequate to the task, and some of the details are discussed here on the website.  On performance:

Now, a 24 kWh lithium-ion battery (about 200 kg) in a competitively priced medium-sized sedan provides a range of about 160 kilometers on a single charge.

But EVs will need the same freedom to go anywhere that drivers of combustion engine cars enjoy today. That means battery switch stations:

At Better Place battery switch stations, drivers enter a lane and the station takes over from there. The car proceeds along a conveyor while the automated switch platform below the vehicle aligns under the battery, washes the underbody, initiates the battery release process and lowers the battery from the vehicle. The depleted battery is placed onto a storage rack for charging, monitoring and preparation for the another vehicle. A fully-charged battery is then lifted into the waiting car. The switch process takes less time than a stop at the gas station and the driver and passengers may remain in the car throughout.

Battery charging provision at places such as homes, offices and public areas is important to broad adoption of EVs. Better Place develops, installs and manages large networks of charge spots that will aim to give consumers the convenience and services they need to confidently make the transition to EVs.

I’m in no position to comment on the feasibility of what Agassi proposes. But I see he was considered worthy of inclusion in Time’s 100 most influential people list in2009. And I certainly enjoyed the buoyancy of his talk and of the website.  I took pleasure from some of the comments of a featured guest blog on the site from Gary Kendall of Sustainability:

A great indicator that disruptive innovations are nearing the all-important tipping point is when powerful incumbents start peddling nonsense masquerading as facts, to sow doubt about the viability of the emerging technology or business model… By scrambling to erect roadblocks to new market entrants that threaten their hegemony, oligopolies are only doing what comes naturally to an organism under attack by an existential threat. And if your job is to find, extract, refine, distribute and sell liquid fuels, then electric cars certainly qualify…

“You EV guys are very well meaning – and we wish you well – but until the world stops burning coal, allow motor manufacturers to continue tinkering with incremental efficiency gains while we drill, baby, spill!”.

Back in New Zealand I ponder a vehicle fleet powered by electricity from wind farms or wave power. Bad news for petrol stations and perhaps for oil companies undertaking the expense of deep sea drilling operations. Perhaps food for thought for the Minister of Energy?  Or is that expecting a bit much?

Still talkin’ (open thread #2)

Here’s another open thread, for discussion of anything not covered in recent posts. In response to a few requests, I have ditched the Intense Debate comment service, and reverted to the WordPress built-in system. I’ve installed a couple of plug-ins to allow comment editing and rating (which caused some weirdness with the blog theme and a late night for me until I worked out a temporary fix). I’ve also switched off comment nesting/threading, so your comments will appear in the order they’re posted. If you’re replying to a particular comment, please use the comment number or link to it (the link is under the number). As before, you’ll need to register and log-in to make a comment. If anyone has any problems with their log-ins contact me (gareth@ the site domain) and I’ll see what can be done.

A note on the comment rating scheme: four positive votes or three negative votes, or more than eight votes in total will give comments distinctive styles. Please try it out — I want to see what they look like! I could change this to make unpopular comments invisible, but only with tweaking. Let me know if it’s something you really want. Feedback on other aspects of the blog would also be welcome.
