Is everybody in? The rise in sea levels is about to begin

Naturally, only a complete curmudgeon would object to any attempt to persuade us to cut our use of greenhouse gases, so the launch of Global Cool is probably a good thing - and, hey, if takes Josh Hartnett flying in from Hollywood on a jet to persuade people to remember to switch off their bedside light before falling asleep, who are we to argue with their priorities?

Indeed, by our calculations, the extra carbon dioxide emitted during the glittering launch for the campaign could be offset simply by all of us in the UK switching off our kettles for the next seven weeks - and that's got to be worth it, right?

What does puzzle us, though, is that the campaign is being built around a poem - written by Jim Morrison and set to music by Perry Farrell. If I were looking for someone to be at the centre of a campaign asking people to avoid excess and waste, and take care of themselves and all they hold dear for the future, a dead junkie wouldn't have been my first choice.

KT Tunstall is also going to be at the London launch - and, certainly, by not playing her music at all, we've helped to save enormously on our emission levels. Perhaps we should encourage KT to help by stopping releasing records altogether? Imagine... just not putting out three albums, with the attendant manufacture, and promotional tours, and trips down to Woolworths - how much otherwise wasted carbon dioxide could be left untouched by such a small sacrifice?
