Al Gore...campaigning and systems

Interesting to see the line-up of the Observer's 2007 ethical awards and that readers awarded Al Gore 'campaigner of the year'. I was also very interested to read in the Observer magazine a recent article from James Traub that started
"Gore was telling me about Ilya Prigogine, a Belgian chemist who won a Nobel Prize in 1977 for his insights into the thermodynamics of open systems, an intriguing subject that has very little to do with global warming. ... We had moved on to complexity theory, in which Gore would really immerse himself if only he had the time, and then to the concept of nested systems, which of course had been developed by the late psychologist Uri Bronfenbrenner...."
I think systems ideas have a lot to offer our current 'climate change and adaptation' agenda so found it interesting to hear where Gore's focus sits in this respect.
I haven't yet fully engaged with what he's been saying recently about energy efficient IT systems, embedded systems and total system design and architecture....but will.
