My critique of the NZI’s “fast follower†report – described as “spirited†by Nevil Gibson in the NBR – has received a swift response from the NZI. We’re Right Behind You was written by NZI chief executive David Skilling and researcher Danielle Boven. Danielle interviewed me about climate issues earlier this year, and has taken the trouble to prepare an extended response to my criticisms. It’s too long to post as a comment, so Danielle becomes HT’s second guest blogger (IPCC lead author Jim Renwick was the first). I have not edited her words, but do offer some comment at the end. Note: Danielle refers in several places to papers 1 & 2. The first paper is the one published this week, the second a forthcoming one which will consider other aspects of climate policy. Over to Danielle….

Big emitters bite back
NZ’s big greenhouse gas emitters have begun a push back against the government’s Emissions Trading Scheme (ETS) and energy strategy. Last week an industry group including the Greenhouse Policy Coalition, Federated Farmers, the Major Electricity Users Group, Business Roundtable, the Chambers Of Commerce, and others wrote to Helen Clark warning that, as Colin Espiner in The Press reported, “the Government’s proposed Energy Trading Scheme (ETS) is being rushed through Parliament without adequate consultation with industry. It says the Government is refusing to release any economic analysis to back its claims the new system will have a negligible impact on economic growth.†Fran O’Sullivan in the Herald provided more context, with news of the first meeting of the government’s Climate Change Leadership Forum, but it’s clear that a coordinated effort to derail the ETS is under way.
Tuesday linkfest
Labour weekend means just that, chez Hot Topic. Catching up with farm work, planting the vege garden, getting a sore back – all in a weekend’s work. But climate change waits for no man, so here’s a compendium of stuff that caught my attention over the last few days.
- Contact Energy has announced plans for a huge – 218 turbine, 650MW – wind farm called Hauauru ma raki, to be built on a remote site south of Port Waikato. NZ turbine builder Windflow Technology has announced plans for new models designed to work in India and China, and Meridian has sent wind experts to Scott Base in Antarctica to advise on building wind turbines to reduce fossil fuel requirements. According to Stuff, they think it could be easier than building in Wellington.
- Still more on the Arctic summer: the NSIDC updates its coverage with some excellent animations, while Cryosphere Today adds an archive of maps of atmospheric conditions over the summer, and introduces a web app that allows iPhone users to monitor sea ice conditions. Another reason why I want one. Technology Review visits Greenland to meet the teams measuring the melt, and down south, satellites spot a huge berg breaking off the Pine Island Glacier.
- On the roof of the world, the Nepali Times reports Kiwi guides describing how the disappearance of ice on the planet’s biggest mountains is changing the climbs.
- Two more good articles from TR: Fixing the Power Grid describes how big batteries (capable of supplying 1MW+ for hours at a time) can provide back up for grid problems, and Tiny Solar Cells looks at nanowire solar cells made by a team at Harvard.
- Carbon emissions from shipping could be as much as twice those from aviation, according to a report from Intertanko. Strong growth in trade has driven emissions to 1.2 billion tonnes oer annum. Meanwhile, the Herald reports on aviation’s attempts to be seen to be more climate friendly – and Richard Branson’s efforts to beat Air New Zealand to the first use of biofuels in jets.
- CO2 absorption in the Atlantic has nosedived, adding to concerns that the ocean carbon sink may be reducing – leaving more of our emissions in the atmosphere [University of East Anglia].
- Coral reef specialists have issued a call to action on the impact of climate change: “We call on all societies and governments to immediately and substantially reduce greenhouse gas emissions. Without targeted reductions, the ongoing damage to coral reefs from global warming will soon be irreversible.â€
- The Daily Telegraph [UK] is in the process of becoming enthusiastically green. Latest evidence is a nifty widget – the Telegraph Earth Pulse – which monitors climate and general environment news.
- A dairy farm can produce as much sewage as a small town (see North & South current issue), but worms can turn it all into mellow compost according to US researchers.
- It looks like a “three-wheeled technicolour shoehornâ€, but the No More Gas will do 75 mph and has a range of 30 miles. OK for getting around town, but I’d still prefer a Tesla Roadster…
- The financial word is getting the climate message: Deutsche Bank thinks that efforts to combat climate change will drive an investment “megatrendâ€, Morgan Stanley estimates that global sales of wind, solar and geothermal power and biofuels could be US$1 trillion a year by 2030, and HSBC is launching a climate change investment fund for investors who want to track companies active in the field.
- HT tends to steer clear of dsicussing peak oil, but the Guardian [UK] covers a new report that claims that we passed peak oil last year, and that global oil production will be halved by 2030. Adds a certain piquancy to energy strategy…
Another Friday roundup
I’m a sucker for pretty computer graphics, especially if they’re didactic. Today’s discovery is a superb Flash animation of the sea level history of Australia and New Guinea, lovingly prepared by Monash University‘s new SahulTime project [ABC coverage here]. From the web site:
The concept of SahulTime is similar to GoogleEarth, except that SahulTime extends each of GoogleEarth’s paradigms through a further dimension in time. Satellite-style images change to reflect coastlines, the icons are time-aware, and even photographs can can be taken through a timewarp to view reconstructed ancient landscapes.
You drag a pointer back along a profile of how sea level has changed over the last 100,000 years, and watch how Australia’s coastline changes, merging with New Guinea. Fantastic. Can we have one for New Zealand, please?
Meanwhile…
- Al Gore’s film An Inconvenient Truth has been passed by a UK High Court judge as fit to be seen by UK schoolchildren, but only with changes to the accompanying teacher’s notes to clarify nine scientific “errorsâ€. News media are buzzing: a few samples – Herald, BBC, and Guardian (UK). The BBC’s environment correspondent provides some context, and Stoat (aka climate scientist and ice gambler William Connolley) looks at how serious the mistakes really are. The right wing roots of the court case are explained by Oil Change International, and one of the “expert†witnesses looks like it might have been the NZ CSC’s own Bob Carter. Not surprising then that former ACT MP Muriel Newman’s NZ Centre for Policy Research site is all over the issue – though she manages to find two extra bonus “errors†from somewhere. Read the judgement in full here. Real Climate’s original review supports the judge’s finding that AIT gets the basic science right.
- New Scientist reports on a Canadian study that finds that to keep global temperature under the EU’s target of 2C above pre-industrial levels, cuts of 90% of emissions will be needed by 2050, much deeper than the 50% reductions already promised.
- The new edition of popular computer game SimCity is to feature global warming, offering players high and low carbon energy options – sponsored by BP. A sign of the times….
New energy and energy efficiency strategies announced
Renewables are the key to New Zealand’s future energy needs, according to the government’s new energy strategy, published today [HTML, PDF]. No new thermal generation should be built over the next ten years, the government is going tell the power generation and distribution state owned enterprises. New generation capacity is expected to come from an expansion of wind and geothermal generation. The energy strategy is complemented by the new energy efficiency and conservation strategy (EECS) [web, PDF], designed to help homes, businesses and transport reduce their energy use.
Announcing the energy strategy, David Parker said (Scoop audio):
The government does not believe it is in the interests of the country for the SOEs to build any more base-load thermal generation. The government will be writing to the SOE generators to make it clear that it expects them to follow this guidance. We are also considering additional measures to ensure our message is loud and clear, for all generators, not just SOEs. Competitive neutrality between the private sector and SOEs is important.
In the transport sector, the government wants to encourage biofuels, greater fuel efficiency, and low-carbon vehicles. It foresees as much as 60% of the light vehicle fleet being electric powered by 2050. The strategy also call for the development of a domestic sea freight strategy, looking to build an integrated rail/sea freight system to reduce reliance on roads. [“Key points†press release]
In her speech launching the EECS, Jeanette Fitzsimmons said:
“This is an action plan to make a real difference to Kiwi families so that they can live in warmer, drier, healthier homes that cost less to heat; for business to become more competitive; and to save money and emissions in the transport sector. The strategy is set to deliver annual non-transport energy savings of 30 PetaJoules per year by 2025. That’s the same as the electricity used by 30 cities the size of Nelson in 2006 or 18 months of coal-fired production from Huntly, at 2006 levels. In transport, cumulative savings by 2025 will be around 4.8 billion litres of fuel.â€
All good stuff, but someone should tell her officials that a PetaJoule is a bit more than 1015 Joules – as defined at the back of the strategy document. That should be 10 to the power of 15, a thousand trillion joules, or 1,000,000,000,000,000 joules. Either that, or Nelson is the most energy efficient town in the known universe. Mike Ward clearly doesn’t need to be mayor…
Reaction so far seems mainly positive. More from me when I’ve had a chance to read the strategy documents in detail.
