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 reaction #2

Wp-Content Uploads 2007 09 Nzets1Two very perceptive pieces of analysis over the last few days,and one deeply misguided one. Rod Oram in the Sunday Star Times takes a look at how nitrification inhibitors could be a major incentive for dairy farmers to get involved in emissions reductions sooner rather than later, and Colin James in the Herald rather gloomily acknowledges the realpolitik of international negotiations:

The odds are that humanity doesn’t think it matters, at least not enough to forgo significant amounts of its material gains or prospects. The odds are that humanity won’t really change its mind until (or if) climate change starts to have effects that cut significantly into material gains and prospects, the necessaries and luxuries of life, and people see it as the cause: that is, when it ceases to be a moral issue and becomes an economic one. That point has not been reached. So world politicians are likely to come up with a suboptimal arrangement to apply when the Kyoto Protocol ends in 2012 and to implement it suboptimally. And so, if the climate change high priests’ measurements and predictions are right and warming isn’t offset by radical new technologies, there is a rough ride ahead.

On the other hand, Roger Kerr of the Business Roundtable in the Dominion Post, grudgingly admits that the ETS looks “responsible and moderate

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].

Full IPCC reports now available

The full text of the Working Group One, Two and Three sections of the IPCC‘s Fourth Report are all now available for free download:

The final section, the Synthesis Report, is in the final stages of government review, and will be adopted at a meeting in Valencia in mid November. Put together, the three reports amount to a compendium of the state of our knowledge about climate change, and our options for dealing with it. The WG2 chapter on impacts in Australia and New Zealand [PDF] is particularly important reading.

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)…
