Hidden treasure is fools gold

The Institute of Professional Engineers New Zealand (IPENZ) has launched a new document, Realising Our Hidden Treasure: Responsible Mineral and Petroleum Extraction. The title says it all, and it’s the same message as the government has been feeding us for the last three years.

First the treasure. The document sets it out in dollar terms. I’ll mention only the fossil fuels here. They estimate the potential value of the resources as $109 billion for coal, $248 billion for lignite, $187 billion for oil and $45 billion for natural gas.

Then the question of responsible extraction. The document is concerned with the environmental effects. There are plenty to be concerned about, but in this post I’ll focus on greenhouse gases, which the document addresses in a short section headed “Can We Manage Greenhouse Gas Emissions?”

Jim Hopkins: vapid, vacuous, pretty vacant

There’s a terrible tyranny in being a columnist for a national newspaper, required to produce entertaining and informative copy every week. It’s a hard job, having an opinion and expressing it cogently. Some writers struggle and succeed, others strive and fail dismally. The NZ Herald — the newspaper of record for NZ’s biggest city — has a couple of fine examples of the latter: old curmudgeon Garth George, who meets the difficulties inherent in his job by ripping off other people’s copy, and red-spectacled “funny man” Jim Hopkins, who has never allowed the facts to get in the way of a good rant.

And what a diatribe he gave us last Friday! Global warming’s gone away, Jim reckons:

There has been a trickle of terror but, by and large, the whole calamitous narrative is a goneburger.

…and…

The conclusion’s inescapable. Either we (literally) cooked our goose a long time ago or global warming’s always been more chimera than catastrophe. Quids in, it’s the latter. This is a crisis of faith, not a crisis of fact.

…and…

We just don’t need to worry about it any more. That’s all. The prediction holds. Global warming has disappeared.

Yes that’s right, because the media isn’t giving global warming the same prominence as a few years ago, the problem must be over. Thank the Lord for that sir. And what a shame that Hopkins’ is talking — not to put too fine a point on it — complete bollocks. Here’s why:

Oceanographers win PM’s science prize for climate work

This year’s NZ Prime Minister’s Science Prize — worth $500,000 — has been awarded to a team of scientists working on climate-related issues at the joint Otago University and National Institute of Water and Atmospheric Research (NIWA) Centre for Chemical & Physical Oceanography. The team carried out ground-breaking research on using iron to fertilise phytoplankton growth in the southern ocean, and its effectiveness at removing carbon from the atmosphere. Team leader Professor Philip Boyd commented:

Around the world, there is a growing lobby, which includes influential people like Bill Gates, for using geo-engineering to claw back some of the carbon dioxide humans are emitting. Our research has shown that adding iron to the ocean is not going to be an effective way to do that.

You can hear Professor Boyd talking about the research in episode #6 of The Climate Show, and Professor Keith Hunter, co-director of the Centre was interviewed in Climate Show #16. “It’s the top prize in science in the country and it’s an outstanding award for science at Otago,” Hunter said today. The centre plans to spend most of its winnings on a state-of-the-art phytoplankton culture facility in Dunedin. Other members of the team were Dr Evelyn Armstrong and Dr Kim Currie of NIWA’s research unit, Associate Professor Russell Frew, Dr Sylvia Sander, and Dr Robert Strzepek (all of Otago University), Dr Cliff Law, NIWA principal scientist, and Dr Rob Murdoch, NIWA’s general manager of research.

The 2011 MacDiarmid Emerging Scientist prize was awarded to Dr Rob McKay, a world-leading glacial sedimentologist at VUW’s Antarctic Research Centre for his work using marine sedimentary records and glacial deposits to reconstruct Antarctic climate over the last 13 million years.

The full list of winners is available here. Congratulations to all.

Powerman: solar PV, net metering and seeing the light in New Zealand

Grid tie solar power is becoming a no-brainer! Photovoltaic (PV) solar power generation has made enormous advances over just the last two years. The cost of panels and assorted gear has fallen dramatically so that in NZ grid tie solar systems in the 2KW peak power range can be purchased for under NZ$10,000 (including GST) from many outfits.

Grid tie PV systems, to make sure its clear what I mean here, are systems consisting of a set of solar panels, often 10 panels of 190W and 45 Volts each, and a grid tie inverter which feeds the solar power into the 240V mains system at your home.

Once installed the power that is generated by the rooftop panels feeds into the 240V mains system. Power required by the home is then derived from this source. If the requirements of the home exceed what’s generated, additional power flows in from the mains and your power meter runs forward as usual. But if your home requires less energy than the panels are generating, often the case on a sunny day, the excess power is fed into the grid and your meter runs backwards, or so it should. More about this below.

The verdict on Durban – a major step forward, but not for ten years

In this guest post, Mark Lynas, author of Six Degrees, High Tide and The God Species, advisor to the president of the Maldives, analyses the outcome of the Durban conference and what it means for the future of international climate negotiations. It’s one the best and most detailed accounts I’ve come across, from someone at the heart of the action. This article was first published at his personal blog.

Following the marathon negotiations session at Durban, all the delegates should now be back home – and if not quite rested, certainly ready to assess the outcome with the benefit of some distance. In this (rather long) post I will look at the key documents agreed in the Durban outcome, and try to offer some sense of what they mean for the climate regime, and for the climate. (Apologies for some jargon, and for unexplained acronyms, which should be familiar to anyone following the negotiations, and without which this post would be even longer still.)

The Durban mandate

During the second week of COP17 the South African presidency operated an ‘Indaba’ system of high-level meetings, where an options paper was gradually whittled down into a decision text on the crucial issue of the future legal form of the UNFCCC regime. Various iterations of this paper produced some rollercoaster ups and downs from the perspective of a small islands state delegate (as advisor to the President, I once again joined the Maldives delegation). The final version, agreed in the small hours on Sunday 11 December — nearly 48 hours after the COP was supposed to have concluded — is titled ‘Establishment of an Ad Hoc Working Group on the Durban Platform for Enhanced Action'(PDF link).
