Revenge of the zombie facts

Dr Vincent Gray is one of the most active of NZ’s little band of cranks. He’s been publishing his “envirotruth” newsletter since the ’90s, always brimful of climate scepticism, and has been a stalwart reviewer of IPCC reports. His most recent contribution to the IPCC process was to make 1,898 comments on the final draft of the Working Group One report – 16% of the total, and, perhaps unsurprisingly, he accounted for 95% of the comments rejected by the authors. Vincent’s offerings are the backbone of the NZ Climate “Science” Coalition site, and I always enjoy reading them.

His most recent, Problems With Surface Temperature Data [PDF], is typical. He asserts it’s impossible to arrive at a meaningful figure global temperature, prefers satellite data but doesn’t believe it, and then states that “Since the amalgamated surface record is unreliable, an indication of temperature change over the past century can be obtained from well-maintained local records. Attempts to correct for the many errors, though not entirely successful, give records of some credibility.” (Otherwise known as the cherry-pickers charter). He then disinters a 1994 paper that found a 60-65 year cycle in global temperature (but I thought that was meaningless) if the data is “detrended”. One wonders what trend was removed. Perhaps the long term underlying rise in temperature? If we ignore the data, it goes away. Magical thinking at its finest.

[UPDATE 6/11/07: NASA’s excellent Earth Observatory posts a very interesting article about James Hansen and the development of the global temperature record. There’s a superb animation of atmospheric flows from space on page 2.]

But the most interesting part of Vincent’s report is the note at the end: “This paper is part of “The Science is not Settled: Major Issues Remain Unresolved by the IPCC: A Report of the NIPDD” (sic) (Non-governmental International Panel on Climate Change) to be published by the Science and Environmental Policy Project, Arlington Virginia.” The NIPCC? Seems this is something Fred Singer at SEPP has set up as a counterblast to the IPCC, and its report is due soon. From Fred’s The Week That Was for Sept 1st:

Highlights of the NIPCC Report

  • Demonstration of the insignificance of human contribution to current warming – using the ‘fingerprint’ method – and why future anthropogenic warming is negligible
  • Why climate models do not agree with observations – the role of feedbacks
  • Evidence that solar activity controls most climate change on a decadal time scale
  • Evidence that future warming will not accelerate sea level rise appreciably
  • No evidence for more storms, hurricanes, droughts, and floods as climate warms
  • How we know that a warmer climate is better than a colder one
  • Evidence that the Medieval Period was warmer than today
  • Evidence that pre-1940 warming was not anthropogenic
  • Problems with data quality and special problems with sea surface temperatures
  • Uncertainties about the CO2 budget, past and future – and of future emission scenarios
  • Changes in ocean heat storage, glacier length, and sea ice coverage indicate climate change – but not whether the cause is anthropogenic or natural

That’s a mind-boggling list. If all the papers show the – how shall I put it politely – “rigorous” approach to the science that Dr Gray demonstrates, the NIPCC report will be a real paradigm shift. Or perhaps not.

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].

There’s no such thing as a free launch

MeltingNew Zealand melted before our very eyes at Wednesday night’s launch of Hot Topic, but serious flooding of the Minter Ellison boardroom was avoided, thanks to carefully planned adaptive strategies (and two large blue buckets). Scott Gallacher from Minter Ellison got things moving, followed by AUT vice chancellor Derek McCormack, who welcomed the arrival of AUT Media’s first book. I did my mini-Al Gore presentation – just the one slide, showing water plunging down a moulin in Greenland – and then David Cunliffe, who holds ministerial portfolios for Immigration, Communications, Information Technology and Associate Economic Development (standing in at short notice for David Parker, the climate change minister), made it clear to all that the government intended to take the issue very seriously. Then it was down to the real business of assessing the carbon neutral status of Grove Mill‘s products. A good night was had by all, including at least one freeloader, who has subsequently offered the contents of his/her “goody bag

Knee deep, and still digging

GreenlandmeltsmallJames Hansen, perhaps the most outspoken of mainstream climate scientists, reckons that unless we take urgent steps to cut emissions we’ll be committing the world to multi-metre sea level rise this century. In this week’s New Scientist, he presents his reasons why:

In my opinion, if the world warms by 2 °C to 3 °C, [..] massive sea level rise is inevitable, and a substantial fraction of the rise would occur within a century. Business-as-usual global warming would almost surely send the planet beyond a tipping point, guaranteeing a disastrous degree of sea level rise.

That’s a controversial viewpoint, and has lead to Hansen being described as “alarmist

Global warming and peak oil

Is peak oil good news or bad news? Much depends on your perspective. The gloomier prognostications about peak oil – living in a world where oil supplies are limited and expensive – suggest that it will be a bigger problem than climate change, and arrive sooner. On the other hand, if we’re forced to cut back on our usage of oil and gas as fuel for energy and transport, we might have a better chance of stabilising atmospheric carbon dioxide at levels low enough to limit the damage from climate change. The IPCC’s high-end scenarios typically assume that there’s plenty of fossil fuel – coal, oil and gas – to get us to double pre-industrial concentrations and beyond. What happens if the oil runs out?
