Biofuels to fly, and other stories

747Air New Zealand is carefully positioning itself as a climate-friendly airline with its latest announcement that it is to trial biofuels in a 747 flight from Auckland in the next couple of years. Working with Boeing, Air NZ will be part of the first commercial trial of biofuel, in a Rolls-Royce-powered jumbo in the next 18 months . The flight will only use biofuel in one engine, and will not carry customers. [Stuff, Herald, BBC, June HT blog on aviation biofuels].

Friday roundup

PolarbearThe Arctic sea ice has begun its autumn freeze after setting a new record for a summer low – a million square kilometres less than the previous record, set in 2005. The NSIDC updates are very interesting, while scientists working in the field described the summer as “remarkable

Cranky about the ETS

 Wp-Content Uploads 2007 08 HomerOur little band of climate cranks couldn’t let an opportunity as big as the NZ Emissions Trading Scheme announcement pass by unremarked. And they didn’t. First out of the blocks was Bryan Leyland, “€œchairman of the economic panel of the New Zealand Climate Science Coalition”, pre-empting the ETS announcement to complain about the government buying offsets for ministerial travel with a press release headed “€œIs your carbon tax really necessary?”

“€œIf there is no evidence of man-made warming in New Zealand – and in the world – this whole charade of cap and trade, and offsetting ministerial travel emissions, should cease forthwith before any more damage is done to our internationally fragile economy.”

Leyland’s views were echoed a couple of days later by a release from Owen McShane, “€œchairman of the policy panel of the New Zealand Climate Science Coalition” (the NZ CSC appear to have enough panels to decorate a small stately home)…

More ice/less ice

PolarsternMore on the Arctic melt: the National Snow and Ice Data Centre updates its commentary on this year’s record ice minimum. As of yesterday, the five day moving average of ice was still moving downwards, but slowly. Their comment on the North West Passage is interesting.

The main, deep channel of the Northwest Passage (Lancaster Sound to M’Clure Strait) has been open, or nearly ice-free, for about five weeks (since August 11, approximately). Of note is the northernmost ice edge ever recorded, at 85.5 degrees North, near the 160 degrees east longitude line.

Meanwhile, the RV Polarstern (see pic), near to completing a voyage through the Arctic as a contribution to International Polar Year, reports that large areas of this year’s ice have only been 1m thick – a 50% reduction on only 6 years ago. When the ship got close to the pole, it started raining. Ursula Schauer wrote (in early September):

A whole day of rain within 150 km of the North Pole came somewhat as a surprise! For the past few weeks, one low-pressure system after another has continuously carried warm air from northern Siberia (15°C at the Lena estuary!) towards the central Arctic Ocean. In this way the sea ice disintegrates more and more right before our eyes.

Meanwhile, I’ve bet Stoat (aka William Connolley) that 2008 will beat 2007’s record low. But only £10…
