Getz it on (bang a gong )

getz(notstan).jpg Hyundai has announced that it will be the first manufacturer to sell an electric car in New Zealand – a Getz modified in NZ by engineer Ross Blades. The petrol engine will be removed and replaced by an electric drive unit and battery pack. Range will be 120 km, with a quick recharge able to boost that to 200 km. Top speed is 120 kph. The first production unit has been sold and will be delivered in November, and Hyundai is planning to produce 200 cars per year. No news on price yet. [Hat tip: frog]

The range is more than enough for most of my needs, but I’d still rather have a Tesla.

Beat the retreat

MarionArawata.jpg New Zealand’s glaciers lost 2.5 km3 (2.2 billion tonnes) of permanent ice from April 2007 to March 2008, leaving 44.9 km3 of ice in the Southern Alps – the lowest amount since NIWA began regular surveys 32 years ago. The picture (credit: “Mr Ice” Trevor Chinn, click for larger image) shows the Marion Glacier in the Arawata Valley in South Westland which has recently retreated above its proglacial lake. The annual survey uses a fixed wing aircraft to record the height of the snowline at the end of summer (and Trevor gets to take the pix). Jim Salinger, NIWA’s principal scientist, says that the survey shows that the glaciers had lost a lot more ice than they had gained over the preceding winter [press release]:

“As a result of La Niña conditions over New Zealand, more easterlies, and warmer than normal temperatures, there was less snowfall in the Southern Alps and more snowmelt. The higher the snow line, the more snow is lost to feed the glacier. On average, the snow line this year was about 130 metres above where it would need to be to keep the ice mass constant.”

The trumpet shall sound

NZGeo08.jpg A cracking issue (#93) of New Zealand Geographic has just hit the streets – a climate change special, complete with free map of both poles. Dave Hansford looks at impacts on NZ flora and fauna, Alan Knowles examines the energy alternatives being developed here, plus there’s a range of features from around the world – including an excellent article on climate change and winemaking. I’ve got a piece in there on the long-range forecast for NZ, but the knees are not mine. I’m biased by taking the NZGeo shilling, but even so the magazine is clearly an essential part of the intellectual landscape of this country and deserves support. Well worth $14.95 of anyone’s money.

Hit somebody! (The hockey song)

0901hockeythumb.png Expect a renewed interest in the shape of hockey sticks, as a new paper in the Proceedings of National Academy Of Sciences (PNAS) by Michael Mann (et al) finds that the last decade was the warmest for at least 1,300 years. The BBC headlines the story “Climate “hockey stick” is revived”, which rather stretches the facts about the controversy (nicely covered in the piece). More coverage at Mongabay, which notes:

The results confirm that temperatures today in the Northern Hemisphere are higher than those of the Medieval warm period, a time when the Vikings colonized Greenland are are believed to have become the first Europeans to visit North America.

Sounds like a red rag to sceptic bulls to me. Expect much nit-picking and fulmination. The rest of us will get on with trying to sort out the problem.

NZETS.jpg The Green Party has just announced that it will support the government’s proposed emissions trading scheme, because “the substantial changes we have won to the ETS justify voting for it”, according to leader Jeanette Fitzsimons. The changes include a “billion dollar” fund from ETS revenues to improve home insulation and heating, new rules on credits for firms established to use new low-carbon technologies, and some improvements on agriculture and biodiversity protection.

“A target for agricultural emissions reduction before 2013 will be gazetted along with other targets for emission reductions. Government has also agreed that there will be investment in a range of technologies and practices which can reduce agricultural emissions, particularly nitrous oxide. These will include not just nitrification inhibitors but also low input farming which can be just as profitable; biogas plants to convert manure to energy; and methods to control soil damage in wet conditions such as herd homes and stand off pads.”

No news yet from NZ First, but Greenpeace were (predictably) pleased with the decision.

[Update 27/8: NZ First has announced that it will support the ETS legislation.]
