Another Friday roundup

NzmapI’m a sucker for pretty computer graphics, especially if they’re didactic. Today’s discovery is a superb Flash animation of the sea level history of Australia and New Guinea, lovingly prepared by Monash University‘s new SahulTime project [ABC coverage here]. From the web site:

The concept of SahulTime is similar to GoogleEarth, except that SahulTime extends each of GoogleEarth’s paradigms through a further dimension in time. Satellite-style images change to reflect coastlines, the icons are time-aware, and even photographs can can be taken through a timewarp to view reconstructed ancient landscapes.

You drag a pointer back along a profile of how sea level has changed over the last 100,000 years, and watch how Australia’s coastline changes, merging with New Guinea. Fantastic. Can we have one for New Zealand, please?

Meanwhile…

  • Al Gore’s film An Inconvenient Truth has been passed by a UK High Court judge as fit to be seen by UK schoolchildren, but only with changes to the accompanying teacher’s notes to clarify nine scientific “errors”. News media are buzzing: a few samples – Herald, BBC, and Guardian (UK). The BBC’s environment correspondent provides some context, and Stoat (aka climate scientist and ice gambler William Connolley) looks at how serious the mistakes really are. The right wing roots of the court case are explained by Oil Change International, and one of the “expert” witnesses looks like it might have been the NZ CSC’s own Bob Carter. Not surprising then that former ACT MP Muriel Newman’s NZ Centre for Policy Research site is all over the issue – though she manages to find two extra bonus “errors” from somewhere. Read the judgement in full here. Real Climate’s original review supports the judge’s finding that AIT gets the basic science right.
  • New Scientist reports on a Canadian study that finds that to keep global temperature under the EU’s target of 2C above pre-industrial levels, cuts of 90% of emissions will be needed by 2050, much deeper than the 50% reductions already promised.
  • The new edition of popular computer game SimCity is to feature global warming, offering players high and low carbon energy options – sponsored by BP. A sign of the times….

Cranky about the ETS

 Wp-Content Uploads 2007 08 HomerOur little band of climate cranks couldn’t let an opportunity as big as the NZ Emissions Trading Scheme announcement pass by unremarked. And they didn’t. First out of the blocks was Bryan Leyland, “€œchairman of the economic panel of the New Zealand Climate Science Coalition”, pre-empting the ETS announcement to complain about the government buying offsets for ministerial travel with a press release headed “€œIs your carbon tax really necessary?”

“€œIf there is no evidence of man-made warming in New Zealand – and in the world – this whole charade of cap and trade, and offsetting ministerial travel emissions, should cease forthwith before any more damage is done to our internationally fragile economy.”

Leyland’s views were echoed a couple of days later by a release from Owen McShane, “€œchairman of the policy panel of the New Zealand Climate Science Coalition” (the NZ CSC appear to have enough panels to decorate a small stately home)…

Gone to the great blue dome: RIP Augie

Augie Auer, the charismatic meteorologist, former TV3 weatherman, and leading light of the NZ CSC, died suddenly last weekend while celebrating his 67th birthday and 35th wedding anniversary in Melbourne. [Stuff, Herald, tributes]. I hope he will be remembered for his service to weather forecasting in New Zealand and his superb TV presentation skills, rather than his idiosyncratic views on climate. The world (and this blog) will be the poorer for his loss.

Shooting fish in a barrel

Sometimes the antics of New Zealand’s band of climate cranks, the self-styled Climate Science Coalition, reduce me to tears. More often they make me laugh. Today’s example of their tomfoolery [PDF] has had me chuckling for hours. Dr Vincent Gray, a former coal researcher and leading light of the NZ CSC, hasn’t published any peer-reviewed papers on climate science (he’s had a few in Energy & Environment, but that doesn’t count). He claims to be a “climate consultant” and an “€œexpert reviewer for the IPCC”, but that doesn’t seem to stop him from spouting nonsense. His latest paper claims:

It is quite impossible to obtain a statistically or scientifically acceptable estimate of mean global temperature or its variability over time, from readings on the earth’s surface.

He then proceeds to criticise the global surface temperature record, which seems to be becoming fashionable in certaincircles. On the one hand…

The oceans constitute 71% of the earth’€™s surface, but sea surface temperature measurements suffer from error to a greater degree than measurements on land.

…but he then proceeds to use satellite records of ocean temperatures, excluding land, because…

The “€œLand” [sic: a typo, he means ocean] record is shown in Figure 2 as it ignores variability specific to land surfaces, but still applies to 71% of the earth.

Funnily enough, he doesn’t find much of a warming trend. If he had used the latest combined land and ocean data he would have had to admit that the satellite record showed warming at 0.18ºK per decade – slap in the middle of all modern estimates of increases in the global average. But he ignores that inconvenient truth and soldiers on, to finish with a magnificent assertion completely unsupported by the preceding argument:

Reliable global, regional and local temperature records show that temperatures variability is cyclic, with a period of about 60 years. The temperature does not display a distinguishable €œtrend. The most reliable records show peak temperatures around 1940 and 2005 and low temperatures around 1910 and 1970. These records are incompatible with a belief that there is a distinguishable upwards €œtrend€™ caused by greenhouse gas emissions.

So if we ignore all the evidence that the world is getting warmer, that means that it can’t be getting warmer. I wonder which windmill Dr Vincent will tilt at next? And who is his Sancho Panza? Not the august personage himself, surely?

A popgun broadside

Dick Hubbard and Bob Harvey, mayors of Auckland and Waitakere City, recently popped over the Tasman to attend a conference on climate change in Melbourne. Invigorated by the event, they issued a press release – Climate Change –€“ The Monster In The Living Room. Hubbard was particularly forthright:

Carbon pricing is imminent, like it or not, and once there is a price on carbon the need for all of us to move quickly and effectively will sharply increase. We must be prepared. Not only must we measure our own emissions as councils but also know what each sector emits. Then we can act collaboratively on reduction.

Rear Admiral Jack Welch, chairman of the NZ €œClimate Science Coalition, took exception, and issued his own press release:

€œThe Auckland and Waitakere mayors have fallen into the carbon trap laid by the likes of the Green Party and Greenpeace, in adding their voices to the unproven myth that emissions of carbon dioxide will threaten the survival of the planet

Unproven myth?

The really monstrous reality is that leaders such as the two mayors are rushing to get on a global warming bandwagon for which there is no valid verifiable scientific proof. The first thing they should check is New Zealand’s official temperature and sea level records, where they will find that the country has been cooling since the El Nino of 1998, and the levels of the Waitemata Harbour have remained about the same for the past 100 years.

No valid scientific proof?

The Rear Admiral is, of course, correct on all counts. The survival of the planet is not threatened by puny humans and their emissions of carbon dioxide. The surface will get a little warmer, enough to cause problems for their civilisation, but the Earth itself will carry on in its orbit until the sun turns into a red giant in about 5 billion years time and swallows it whole.

Nor is there any “valid verifiable scientific proof” of the existence of a global warming bandwagon. There’s plenty of evidence for global warming, and what’s causing it, but no-one has found a wagon with a band playing – what, The Sun Has Got His Hat On? As for New Zealand temperatures and the sea level measured in Waitemata Harbour, these are well-known proxies for the global average, not just a couple of figures from a small corner of the South Pacific without much influence on the numbers for the whole world.

Bob and Dick, I hope you are feeling suitably chastised. The rest of us can sleep easy in our beds, secure in the knowledge that a fine old sea-dog is steering the ship of state towards…

Oh, bugger.
