Another Hot Topic, skiing’s future, batteries, kites, u.s.w.

There’s another Hot Topic on the bookshelves – not in NZ, but in the UK. Sir David King, the sometimes controversial scientific adviser to Tony Blair has (with Gabrielle Walker) penned The Hot Topic: How to Tackle Global Warming and Still Keep the Lights On. Reviews in The Times and The Guardian. It will no doubt make its way over here eventually.

Blues from an airplane

Two Otago University physicists, Inga Smith and Craig Rodger, have calculated the CO2 equivalent emissions generated by international tourist visits to NZ, and find that in 2005 the return flights accounted for almost 8 million tonnes of CO2e – about the same as emissions by the country’s entire power sector – around 10 percent of total NZ emissions. They then calculated what it would take to offset those emissions in NZ, and found that most approaches were either not feasible or too expensive. Not suprisingly, this has got quite a few people in a tizzy (Herald & Herald, NBR, Stuff, NZ News UK), because if international travellers begin to worry about their carbon footprints, then 20 percent of our export earnings are at risk.

This is not news. I drew attention to this vulnerability in Hot Topic. Air New Zealand has been very keen to establish its green credentials by working with Boeing on biofuels for avation, and looking at offset schemes in the conservation estate with DOC. In fact the whole tourism sector has seen this coming for some time. What’s interesting is the numbers, and I won’t be commenting on those until I’ve had a chance to see the paper. There are a lot of open questions, too, about how to approach offsetting our tourism business. The authors appear to assume that this should all be done in NZ, and therefore make Helen Clark’s “carbon neutral country” ambition harder to achieve – in fact the NBR (and David Farrar) seem keen to spin this as a government policy problem. The NBR’s intro (above an otherwise fine story) is particularly egregious:

New Zealand’s adoption of a carbon neutrality policy, and the world’s toughest emission reduction targets, will have a disastrous effect on its biggest foreign exchange earner, tourism, and there are no solutions in sight, university experts say.

Now I don’t think that’s what Smith & Rodger were saying at all, but I’ll wait until I see the paper…

There are lots of things to consider. First, the global aviation industry is working on its own emissions regulation framework in part to try and forestall the sort of mandatory scheme threatened by Europe, and as a PR exercise to keep valuable long distance travellers flying. So airlines are likely to be looking at an international offset scheme. Within that, there will have to be some rules about where the emissions generated by travelling are accounted for. All incoming flights in the destination nation, perhaps? Not good news for NZ because of the length of our flights, but there’s nothing to say that the offsets have to be created in that country. Officials looking at ways of achieving Helen Clark’s carbon neutral ambition are already considering that it might be achieved by buying reductions in other countries. And if that’s the cheapest way to do it, why not?

But the fact remains that tourism in NZ is exquisitely vulnerable to consumer perceptions in our prime markets. If long distance flights become uncool, business here will suffer. Like the food miles issue, this is not something we can dodge – it has to be confronted head on. It’s not a problem of the government’s making, but it is one this government (and the next one) will have to help with.

I don’t like Mondays

Lady Young, head of the UK’s Environment Agency, thinks that coping with climate change demands wartime urgency, as the Telegraph [UK] reports:

“This is World War Three – this is the biggest challenge to face the globe for many, many years. We need the sorts of concerted, fast, integrated and above all huge efforts that went into many actions in times of war. We’re dealing with this as if it is peacetime, but the time for peace on climate change is gone – we need to be seeing this as a crisis and emergency,” she said.

Meanwhile, the Observer covers a new report from a peace group:

This stark warning will be outlined by the peace group International Alert in a report, A Climate of Conflict, this week. Much of Africa, Asia and South America will suffer outbreaks of war and social disruption as climate change erodes land, raises seas, melts glaciers and increases storms, it concludes. Even Europe is at risk.

Greenhouse gas emissions continue to increase, and the International Energy Agency sees “inexorable”growth in energy demand over the next 30 years with a risk of more coal being burned. It does suggests a 450ppm CO2 limit might be achievable, but:

“Exceptionally quick and vigourous policy action by all countries, and unprecedented technological advances, entailing substantial costs, would be needed to make this case a reality.”

Not much hope of that. And the China Post says EU officials reckon that China will reject binding limits on emissions in any post-Kyoto deal. The words “hell” and “handbasket” spring to mind…On the upside? Bryan Appleyard in the Sunday Times [UK] looks at options for “fixing” climate through technology (well worth a read), scientists at Harvard and Penn State reckon they’ve found a way to speed up a natural weathering process to neutralise ocean acidity and remove carbon from the atmosphere, and Technology Review reports on a Dutch biofuel company working with a California-based venture capital outfit to develop catalysts that can turn organic matter such as waste wood into biocrude – chemicals that can be processed to make biofuels. If you’ve got money to invest, the Observer [UK] reckons that one of a new breed of green investment funds might be a good place to put it.

Formerly the weekend roundup

Saturday’s promised omnibus extension never arrived, in part because of the arrival of a big cat on my computer, so here’s a Tuesday update.

Tuesday linkfest

Labour weekend means just that, chez Hot Topic. Catching up with farm work, planting the vege garden, getting a sore back – all in a weekend’s work. But climate change waits for no man, so here’s a compendium of stuff that caught my attention over the last few days.

  • Contact Energy has announced plans for a huge – 218 turbine, 650MW – wind farm called Hauauru ma raki, to be built on a remote site south of Port Waikato. NZ turbine builder Windflow Technology has announced plans for new models designed to work in India and China, and Meridian has sent wind experts to Scott Base in Antarctica to advise on building wind turbines to reduce fossil fuel requirements. According to Stuff, they think it could be easier than building in Wellington.
  • Still more on the Arctic summer: the NSIDC updates its coverage with some excellent animations, while Cryosphere Today adds an archive of maps of atmospheric conditions over the summer, and introduces a web app that allows iPhone users to monitor sea ice conditions. Another reason why I want one. Technology Review visits Greenland to meet the teams measuring the melt, and down south, satellites spot a huge berg breaking off the Pine Island Glacier.
  • On the roof of the world, the Nepali Times reports Kiwi guides describing how the disappearance of ice on the planet’s biggest mountains is changing the climbs.
  • Two more good articles from TR: Fixing the Power Grid describes how big batteries (capable of supplying 1MW+ for hours at a time) can provide back up for grid problems, and Tiny Solar Cells looks at nanowire solar cells made by a team at Harvard.
  • Carbon emissions from shipping could be as much as twice those from aviation, according to a report from Intertanko. Strong growth in trade has driven emissions to 1.2 billion tonnes oer annum. Meanwhile, the Herald reports on aviation’s attempts to be seen to be more climate friendly – and Richard Branson’s efforts to beat Air New Zealand to the first use of biofuels in jets.
  • CO2 absorption in the Atlantic has nosedived, adding to concerns that the ocean carbon sink may be reducing – leaving more of our emissions in the atmosphere [University of East Anglia].
  • Coral reef specialists have issued a call to action on the impact of climate change: “We call on all societies and governments to immediately and substantially reduce greenhouse gas emissions. Without targeted reductions, the ongoing damage to coral reefs from global warming will soon be irreversible.”
  • The Daily Telegraph [UK] is in the process of becoming enthusiastically green. Latest evidence is a nifty widget – the Telegraph Earth Pulse – which monitors climate and general environment news.
  • A dairy farm can produce as much sewage as a small town (see North & South current issue), but worms can turn it all into mellow compost according to US researchers.
  • It looks like a “three-wheeled technicolour shoehorn”, but the No More Gas will do 75 mph and has a range of 30 miles. OK for getting around town, but I’d still prefer a Tesla Roadster…
  • The financial word is getting the climate message: Deutsche Bank thinks that efforts to combat climate change will drive an investment “megatrend”, Morgan Stanley estimates that global sales of wind, solar and geothermal power and biofuels could be US$1 trillion a year by 2030, and HSBC is launching a climate change investment fund for investors who want to track companies active in the field.
  • HT tends to steer clear of dsicussing peak oil, but the Guardian [UK] covers a new report that claims that we passed peak oil last year, and that global oil production will be halved by 2030. Adds a certain piquancy to energy strategy…
