Further to one of my recent posts - Politics and the Church of England - the archbishop of Canterbury Rowan Williams wrote an editorial - "A planet on the brink" in yesterday's Independent which contains neither an environmental diatribe, nor a political rant, nor the cold and cruel analysis of economists who have been known to frequent The Commons.

The analysis is nevertheless muddy. Williams, and the Church of England, have taken up various bad ideas... and consequently are supporting the idea of 'contraction and convergence' as a means to reduce global greenhouse gas emissions. I have attempted an analysis of such a scheme here (PDF).
