Clearing the decks

A few quick links before I post on the government’s just announced energy strategy: cleaning out the tabs in my web browser…

  • Professor Graham Harris of the University of Tasmania addresses the issues I raised in my “ecological overdraft” post a few days ago, in Sleepwalking Into Danger – an article for ScienceAlert: “It is time to admit how little we know and face the risks of planetary degradation – this goes way beyond climate change. Biodiversity isn’t just birds, primates and whales; it is planetary function and resilience.”
  • The Royal Society For The Protection Of Birds is planning [Guardian, BBC] to allow the sea to reclaim 728 hectares of coastal land in the Essex marshes on Britain’s east coast to restore habitat for wildlife – and as a pragmatic adaptation to rising sea levels. Could we see the same sort of thing here?
  • The Andrill project – a sea floor drilling effort under the Ross Ice Shelf involving NZ and US scientists – is using nifty Apple computers, so Apple has posted an interesting perspective on the work being done. New drilling season starts soon.
  • Brian Fallow in the Herald takes a look at the cost of carbon in the new ETS and speculates about ongoing impacts on the government’s accounts.
  • Carbon emissions from shipping may be much higher than previously thought, according to The Independent (UK).
  • German solar power company Conergy is planning a 500 turbine windfarm near Broken Hill in New South Wales. Meanwhile, BusinessWeek (US) profiles entrepreneur John O’Donnell, who has bought into Aussie scientist David Mills solar thermal designs, and plans to build a lot of generation at costs competitive with coal. With Silicon Valley money, and soon.
  • The Dominion Post digs up some advice to government on dealing with “environmental refugees”. NZ will probably want to help small Pacific nations, but refugees from the Asian megadeltas might be another matter.

Emissions Trading Scheme workshop: final thoughts

Wp-Content Uploads 2007 09 Nzets1-3Two thought provoking days, and a crash course in carbon trading (and carbon trading politics), leaves me with a few key comments (and many more questions). There’s lots of devil in the detail in the documents (which are many, and often thick) – but these are my headlines.

Into ecological overdraft

Globe07In the final chapter of Hot Topic, I refer to the concept of global overshoot: the idea that human activities are exceeding the planet’s ability to regenerate resources. It’s the ultimate meaning of sustainability – living within our planetary means. This year we started eating into our ecological overdraft on October 6th – three days ahead of last year, and the best part of month earlier than in 2000. The Global Footprint Network calculates Ecological Debt Day:

As humanity’s consumption of resources increases, Ecological Debt Day creeps earlier on the calendar. According to current calculations, humanity’s first Ecological Debt Day was December 19, 1987. By 1995 it had jumped back a month to 21 November. In 2007, with Ecological Debt on October 6, humanity’s Ecological Footprint is almost thirty per cent larger than the planet’s productivity this year. In other words, it now takes more than one year and three months for the Earth to regenerate what we use in a single year.

ETS workshop: day 2 – the trees strike back

Wp-Content Uploads 2007 09 Nzets1-2OK, perhaps I was exaggerating about foresters being happy. On day two of the government’s Emissions Trading Workshop in Christchurch last Friday the policy on pre-1990 forests was described as “blatant property theft

ETS workshop: day 1

Wp-Content Uploads 2007 09 Nzets1-1Just a note: enjoyable is perhaps not the best word for a day going through the detail of the framework for the NZ Emissions Trading Scheme (ETS), but it was certainly useful to have officials walk us through the design of the new system, and just as intriguing to gauge the response from the floor. To a first approximation, foresters happy, big emitters less so. Two key points. The ETS is clearly intended as a stepping stone to a long term system for post-Kyoto operation, but in the absence of any concrete guidance on where the world is going to go, much of the detail remains to be worked on. There are “2007 decisions
