Black is the new white

homer.jpg Once again the sceptic-friendly opinion pages of the Herald provide noted NZ denier Chris de Freitas with a platform to spout the most astonishing tripe. It seems CdF reacted badly to a Reuters report about Tuvalu’s concerns about sea level rise. So he rushes to assure the Pacific island nation that their problem has nothing to do with climate change:

There is some inundation evident on islands in Tuvalu, but global warming is not the cause. It is the result of erosion, sand mining and construction projects causing an inflow of sea water.

That’s a relief. An associate professor in the geography department at Auckland University knows better than the world’s climate scientists and the government of Tuvalu. I hope the people of Tuvalu are suitably relieved.

Unfortunately, Chris undermines his good deed by continuing to talk utter nonsense. And “utter” is a mild description.

Here come the warm jets

Hot Topic has devoted a lot of posts to events in the Arctic over the last northern hemisphere summer. The loss of sea ice was dramatic – there was 25% less ice in September than the previous record, set in 2005. The little graph to the left shows just far off the trend line last year’s September area really was. And as I posted yesterday, recent studies suggest that the Arctic is primed for more significant losses in the near future. If the reduction in summer sea ice continues, there are some pretty major implications for the climate of the northern hemisphere and for our modelling of the global climate, and it’s those things that I want to consider in this post. Please note: I am not a climate scientist, and there are a lot of ifs and handwaves in this argument, but bear with me…

A lie repeated is still a lie

It’s climate sceptic week at the Herald. On Monday they provided a platform for Bryan Leyland of the NZ C”S”C to repeat his tired old opposition to government energy strategy (nicely rebutted by I/S at No Right Turn), and this morning they give room to Garth George to offer his thoughts under the headline “Great global warming debate a bunch of hot air“. Garth’s views are not news – he’s been running this line for ages – but I am frankly astonished that the powers that be at the Herald allow him to repeat lies. Since fact-checking at the paper seems to have gone on holiday, it falls to me to provide the correction.

False equivalence and the climate “debate”

One of the more bumptious of NZ’s tame sceptics is University of Canterbury philosopher and “eminent scientist” Associate Professor Denis Dutton. A key member of the NZ C”S”C, he is perhaps best known for creating the rather good Arts & Letters Daily web site – and selling it for a considerable sum. He has now embarked on a new site – currently in beta – called Climate Debate Daily, with another UC philosopher, Doug Campbell. You might expect me to welcome a new and “neutral” climate site, but I believe it completely misrepresents the reality of any “debate” that might exist, and is in effect a new tactic to give credence to sceptic effluvia. Here’s how they describe their aims:

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.”
