Poor Amanda Baillieu, much loved editor of BD, has had to resort to climate scepticism (BD 6/11). COP15 in Copenhagen is a huge challenge and a great opportunity for us all, so burying our heads in the sand and hoping it will go away won't get anyone very far. I shall be debating the roles and responsiblities of architects and engineers at the next Edge Debate on 19th Nov in the Danish Embassy and will let you know the outcome.
