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?


  • 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….

  1. RealClimate’s latest post describes the judge’s characterisation of the nine ‘errors’ in Gore’s film as substantially flawed, and explains why. I didn’t need any convincing, but it is good to see the complacency of the judge’s findings punctured.
