I was pleased to read the letters on sustainability (NCE last week) but am amazed that there can still be nay-sayers.
Perhaps you could review Al Gore's An Inconvenient Truth, which provides answers to most such doubts.
The cientic community is fully agreed that global warming is happening and that mankind is inuencing this change. There are many vested interests in denying this, hence the stance taken by the popular press. I hope NCE can see through this - after all aren't engineers supposed to be applied scientists?
However, as shown by the Stern Review, we must do far more to reduce CO emissions. Surely a win-win approach, economically and environmentally, is to improve energy efficiency?
But of course, this does not give engineers big new projects to build.
