Clearing the decks #2

Time to catch up with some climate stuff that I’ve accumulated over the last couple of weeks.

  • Auckland lawyers Lowndes Associates have become the first legal firm in NZ to achieve CarbonZero certification – which means that they’ve taken steps to measure their carbon emissions, actively reduce them, and then have bought credible offsets to cover the rest.
  • The first hints of NIWA’s new regional climate projections are beginning to emerge. By the end of the century, Southland could be as warm as today’s Bay Of Plenty. And Jim Salinger, who first noticed that we were warming up, was given a good profile by the Herald.
  • A belated mention for the Be The Change campaign, a climate change awareness campaign that trundled up the country in a bus in the last couple of months of the year. As the SST reported: “From Bluff to Kerikeri, the Be The Change bus tour is a Greenpeace, Oxfam, and Forest and Bird campaign to get ordinary New Zealanders working to stop climate change.”
  • The NZ Stock Exchange’s carbon trading market, TZ1, is aiming for a mid-year launch, and has appointed former Vector CEO Mark Franklin to head up the operation.
  • The German developed SkySail system for sail-assisted shipping (as featured in HT) is about to get an extended sea trial on a voyage from Europe to Venezuela, Boston and back: “Under favorable wind conditions, the 160-square meter kite shaped like a paraglider is expected to reduce fuel costs by up to 20 percent or more ($1,600 per day) and cut, by a similarly significant amount, its carbon dioxide emissions.” [Yahoo News, Guardian [UK]] There’s lively discussion of the pros and cons over at Frogblog.
  • Some new science: another study confirms that IPCC sea level rise projections are conservative – pointing out that in the last interglacial levels rose by up to 1.6m per century. Work on the Paleocene Eocene Thermal Maximum 55 million years ago, considered the best historical analogue for the present situation, confirms that initial warming caused massive carbon cycle feedbacks that boosted temperatures even further. In the Arctic, warming peaked at about +24C.
  • Some turn of the year roundups: Technology Review covers the year in energy and nanotech (good news for batteries), The Independent [UK] rounds up the climate news, New Scientist brings an earth science perspective, while NOAA presents a nice graphic of the year’s extreme weather events.
  • At Gristmill, Tom Athanasiou takes a perceptive look at the post-Bali world, and Joe Romm explores some of the latest thinking on what sort of target we should be aiming for. Bottom line: we may already be overshooting. And at the New York Times, Jared Diamond explains the collision between population growth and consumption growth. There’s a crunch coming.
  • Finally, NZine reviewed Hot Topic, and liked it: “I strongly recommend everyone to read this book, but especially recommend it to those who make decisions on action to counter the impact of global warming and those who are able to influence the thinking of others on this issue.”

The Herald sends good sense on holiday

The silly season is obviously taking a toll on editorial judgement at the Herald. Yesterday they ran an astonishing column by Malcolm McPhee – Climate of fear starting to make my temperature rise – which is breathtakingly nonsensical, and also provided space for Jim Hopkins to take a (ritual for him, tired and boring for the rest of us) swipe at climate science in his column. Today, Fran O’Sullivan includes amongst her top ten stories for 2008 – at number three, no less – climate change science consensus breaks – basing her judgement on a list of 400 “scientists” issued by a Republican Senator and his team of tame climate deniers. McPhee and O’Sullivan deserve debunking (see below), but Hopkins’ taste in eyewear is so atrocious ( 😉 ) that I’ll take pity on him and leave him alone (for now).

The canary croaked

From AP (via CNN): “The Arctic is often cited as the canary in the coal mine for climate warming,” said Zwally, who as a teenager hauled coal. “Now as a sign of climate warming, the canary has died. It is time to start getting out of the coal mines.” The annual American Geophysical Union meeting in San Francisco is bringing bad news about the Arctic – most of it listed in the foregoing linked article. One paragraph is particularly shocking:

Still to be released is NASA data showing the remaining Arctic sea ice to be unusually thin, another record. That makes it more likely to melt in future summers. Combining the shrinking area covered by sea ice with the new thinness of the remaining ice, scientists calculate that the overall volume of ice is half of 2004’s total.

In three years, half of the summer ice has gone. In Hot Topic I suggest that it might all be gone in my lifetime – and I thought I was being pretty daring, given that the IPCC talks about the end of the century. One ice modeller who has been predicting an early demise for the summer sea ice is the US Navy’s Wieslaw Maslowski. From the BBC:

“Our projection of 2013 for the removal of ice in summer is not accounting for the last two minima, in 2005 and 2007,” the researcher from the Naval Postgraduate School, Monterey, California, explained to the BBC. “So given that fact, you can argue that may be our projection of 2013 is already too conservative.”

RealClimate is providing coverage of AGU highlights (here, here, here and (update – sea ice specific) here. The Herald runs with a very US-angled Reuters story. As I’ve pointed out before, the consequences of the loss of summer sea ice in the Arctic for northern hemisphere climate is not known, but I would expect that there’s some urgent work being done to find out. We’re into the land of the unknown unknowns, and there’s nothing we can do to stop it.

Weekend roundup #12 & #35

Thousands of diplomats are on the road to Bali to start the negotiations for a post-Kyoto emissions reductions deal. I’ll be posting more on that as the conference progresses, but in the meantime Brian Fallow provides some useful context in the Herald, and Liz Banas at Radio NZ National produces an excellent Focus On Politics on the conference (listen live at 5-10pm Saturday, podcast available). Meanwhile, the UN turned up the pressure by issuing its latest Human Development Report [PDF], which gives us only ten years to get down to serious action.

  • To get up to speed with cap and whatever, the US-based Tomales Bay Institute has issued a concise little report , Carbon Capping – A Citizen’s Guide, which gives a good overview of how carbon trading works [PDF]. Very US-centric, and not exactly highbrow, but very clear and with a great glossary (via desmogblog).
  • Oxfam issued a briefing paper, Climate Alarm: Disasters increase as climate change bites [PDF], which concludes that climate change is already increasing the number of disasters affecting communities around the world. “The total number of natural disasters worldwide now averages 400– 500 a year, up from an average of 125 in the early 1980s. The number of climate-related disasters, particularly floods and storms, is rising far faster than the number of geological disasters, such as earthquakes.” [BBC], Independent (UK)]
  • I’ve been getting quite a few hits after TV3 featured New Plymouth’s electric car builder Gavin Shoebridge, featured here a few months ago. Apparently his YouTube pages (First Run here) have had more than 100,000 hits. A bit more than HT. It seems we’re less sexy than his Tredia…
  • On the clean energy front, the Aotearoa Wave and Tidal Energy Association reckons that tidal and wave power could be producing electricity in NZ in five years, there are discussions in Europe about building a 8,000km DC power grid to link giant windfarms scattered around the continent (so that somewhere always has wind), and The Guardian reports on research into cheap solar photovoltaics using organic polymers.
  • The whinging by big emitters about the ETS continues: Fran O’Sullivan details complaints by Solid Energy and Air NZ chair John Palmer about the “lack of debate” and the rubbishing of the NZI’s Fast Follower report (who, me?), while John Pfahlert of the Petroleum Exploration and Production Association of New Zealand is given space by the Herald to add to the noise. More sensibly, on the other side of the world, British business lobby group the CBI (not a notably left-wing organisation) has called for fundamental change in British business, and Prince Charles has whipped up a statement signed by many of the world’s largest corporates urging the Bali conference to take serious action. From the Herald: “Contrary to the argument that mandatory pollution cuts would harm the economy, the business leaders’ petition says ambitious emissions reductions would “create significant business opportunities“. [Update: Full communiqué available here.]
  • Fonterra has commissioned a report into its carbon footprint [Herald , Scoop], AgResearch is going to analyse the lifecycle carbon footprint for sheep meat, and MAF prepared a report [PDF] for the Primary Industries 2020 Summit, held in Christchurch this week, that warns: “The drivers [of change] are global warming, climate change, and extreme weather; energy cost and supply; geopolitical power shifts, and international trade and investment; ecosystem degradation, and water quality and availability; demographic shifts; and technological advances.”
  • Meridian hopes to convert Stewart Island to 100% renewable energy, starting the process in January.
  • Further south, the Andrill project has been making rapid progress on another core from the seabed in McMurdo Sound. By now they should have a 1,100m core to set alongside last year’s 1,285m core – 20 million years of climate information drilled from the seabed.

Chris hates Greenpeace

False balance time at the Herald. Last week they gave Greenpeace climate campaigner Susannah Bailey a chance to look at how certain sectors of the business community (Greenhouse Policy Coalition, Business Roundtable etc) are lobbying against current plans for an emissions trading scheme, this week they give NZ Climate “Science” Coalition science advisor Chris de Freitas space to express a different point of view. Bailey’s language was a deal more measured than de Freitas, who indulges in some vibrant green-bashing:

The fanatical name calling and personal attacks expose the strong ideological elements that drive global warming alarmist thinking. It’s as if the depth of passion is overcompensation for doubt and uncertainty. Why else would environmentalists squander so much effort trying to discredit individuals and organisations who disagree?

Warning: I’m about to squander some time trying to discredit de Freitas – whose grasp of the underlying science seems a little – how shall I put this – shaky for an associate professor in the School of Geography, Geology and Environmental Science at the University of Auckland.
