Everyone’s been slagging off the Emissions Trading Scheme for failing to reduce emissions. PCE: Returned ETS bill a failure University of Canterbury: Greenhouse gas emissions trading scheme more or less dead Labour: National’s ETS will mean burning more coal; failure to reduce emissions And here’s the NZ carbon price collapse: Market prices from Carbon Commtrade …

Over the last forty years, airlines have not been profitable. Despite the massive and ongoing growth in air travel, the whole industry has manged to return an average of about 0.1% on revenue, which is as close to zero as makes no difference. So what happened and what’s going to happen when airlines start getting …

Sustainable carrying capacity – or what are limits anyway?

Last week, the Royal Society published two papers on the sustainable carrying capacity of New Zealand. I’ve been working on these for a while but, as ever, I don’t feel like I authored them. Instead, they’re a consolidation of discussions with experts, reviewed by yet more experts. There’s a huge list of names of the …

There is fundamental question that baffles anyone who is paying attention: Global greenhouse gas emissions continue upwards at a faster rate than the worst of predictions. Climate change is a clear existential threat to civilisation, and yet our responses have been trivial and ineffective. At a society level, there is insufficient political mass to drive …

How much can we reduce NZ’s greenhouse gas emissions, at what cost, right now?

That’s a big question, with lots of data-heavy answers, so let’s sum that all up in one graph: This is the cost curve1. Each action or new technology is a block on that curve2. The width is the saving of emissions; the height is the cost. The options are sorted by cost, because we want …

“Carbon capture and storage: Fundamental thermodynamics and current technology”, Shannon Page, et al, Energy Policy, 37 (2009), pp 3314-3324 New Zealand’s energy system is pretty unique. We’re isolated and can’t trade electricity with anyone else, we’ve got more hydro than nearly anyone else, geothermal’s big here, and we’ve vast amounts of coal that we’ve yet …

Back on the Mitochondrion head-banging trek. It was doing weird stuff, as usual, but when it’s doing really weird stuff then there’s probably a problem deep, deep down in the code. Spend the day looking, and trying to sort out other things. Power regulator still exploding. NFI but I have a backup plan. Can’t reproduce …

The terms of the Select Committee on Climate Change are out (PDF, at the end) and they’ve dropped the ludicrous call to rake over the science once again. “The science is pretty clearly established,” Dunne said. “It’s somewhat ludicrous and arrogant to expect a New Zealand parliamentary committee to review the science which the IPCC, …

(For those of you not in Wellington, NZ, it’s a tad windy here. So we’re building three wind farms, two big, one small, within ten miles of the city. One is close to my in-laws’ farm. I don’t know of any other city that’s building so many, so close. Then again, there’s no other cities …

I know there’s probably not too many ACT voters here, but ffs, Rodney’s latest speech on climate change could have been written by the nutters. It’s like looking into a parallel world, where words don’t mean what you or I might think they mean: “ACT’s commitment to freedom commits us to something else too – …

Silly me, I’d have thought that a press release mocking the RSNZ as “a harem of whores” and calling the Society “Floozies for Fascism”, “Tarts Against Technology”, and “Doxies for Despotism” was actually an ironic, if slightly unhinged, way of mocking the Climate Science Coalition (our main critics who, truth be told, are much more …

The Royal Society of New Zealand released its statement on climate change last week. No, I didn’t write it, we have real climate scientists for that, but I did comment on the drafts. It says what the Royal Society of London, the US National Academy of Sciences and all the rest have said, namely that: …
