Air travel carbon costs

A380The Economist uses the climate protest at London’s Heathrow airport as a peg upon which to hang an overview of the difficult carbon prospects for the international aviation industry. An emissions trading scheme is being drawn up under the wing of the UN, and the European Commission plans to make carbon trading compulsory for all EC carriers in 2011. The Economist is admirably straightforward in its judgement:

The introduction of carbon-trading is a welcome step by governments that are not yet willing to consider a carbon tax. The air-travel industry should have to stump up for the pollution it causes. And anyone priced out of a cheap holiday in Spain might like to consider a week-long camping break near Heathrow.

Good job they didn’t mention long haul holidays…

Electric cars or coal-to-diesel?

TeslaThe carbon neutral flagship of New Zealand’s power sector, Meridian Energy, has announced that it’s planning to start trials on electric cars next year [Stuff, Herald] . CEO Keith Turner also announced a new service specialising in helping to design and build energy efficient homes, and a new environmentally friendly Wellington headquarters. Discussing the car trial, Turner said:

“The prize in making the move to electric vehicles comes when you recharge them with renewable electricity. Meridian will be able to demonstrate renewable, zero-emission, certified carbon neutral mobility.

First forecast for the next ten years

FishResearchers at the Hadley Centre in Britain have produced the world’s first short range climate forecast, covering the next ten years. And there are no surprises, it’s going to get warmer. From New Scientist:

Although average global temperatures have been relatively flat in recent years, the model says they will start rising again next year. At least half of the years between 2009 and 2015 will exceed the current warmest year on record. By 2015, global temperatures will be 0.5 °C above the average value for the last 30 years.

Arctic ice sets new record

Ice070810I follow the Arctic sea ice extent at Cryosphere Today. The site publishes pictures, maps and graphs of sea ice in the Arctic and Antarctic, derived from NASA satellite data. They’ve just announced a worrying new record:

Today (August 9th), the Northern Hemisphere sea ice area broke the record for the lowest recorded ice area in recorded history. The new record came a full month before the historic summer minimum typically occurs. There is still a month or more of melt likely this year. It is therefore almost certain that the previous 2005 record will be annihilated by the final 2007 annual minima closer to the end of this summer. In previous record sea ice minima years, ice area anomalies were confined to certain sectors (N. Atlantic, Beaufort/Bering Sea, etc). The character of 2007’s sea ice melt is unique in that it is dramatic and covers the entire Arctic sector. Atlantic, Pacific and even the central Arctic sectors are showing large negative sea ice area anomalies.

I find this news disturbing for two reasons. First, the fact that the new record should be set so early in the season. That suggests that there is a lot more melting to go. The second is the language: normally cautious scientists seldom use words like “annihilate

Cap in hand on carbon trading

Brian Fallow took a detailed look at carbon trading and pricing in yesterday’s Herald.

Mark Lewis, a London analyst with Deutsche Bank, has raised eyebrows by forecasting a price of €35 ($63.31) a tonne for allowances traded on the internal European emissions market over the 2008 to 2020 period. That compares with a market price of around €20 for 2008. It is also about five times higher than the $13 a tonne carbon price the Government uses in estimating the value of this country’s Kyoto liability in the Crown accounts.

In a month or two the government will be announcing its design for a domestic emissions trading scheme, and the relationship between the NZ price and the international price will be an important feature. Another will be how the scheme phases in various sectors of the economy. Labour has signalled it wants an “all gases, whole of the economy
