Skinny celebs and climate change

Keira Knightley has been gabbing away to the Radio Times about fame, public image and her acting skills. Back on cinema screens soon in September, Knightley gave a frank review of her acting skills (dubious) and railed against popular opinion about her good looks. She said: "Somebody goes, 'Gosh, you're pretty.' Thanks. I've got good genes! OK, I'm on the cover of a magazine but somebody else does the hair, and the make-up, and airbrushes the f*** out of me".

All this self degradation does wonders for her image as a straight talking siren amidst a sea of pampered Hollywood divas, I'm sure. Nothing against the lovely lady (she's only famous, thin, beautiful, rich - all at the same age as me...) but I find it hard to take someone this emaciated seriously....

James is musing over the merits of last weeks Climate Change Camp and asks whether it was really worth the effort...I'm on the fence as far as global warming goes. Our fossil fuel emissions may or may not be doing irreversible harm to the planet...But either way I believe in respecting our rock and trying to do our bit - recycling, sharing lifts etc.. - to make it a nicer place. Look at Beijing, covered in smog thanks to human pollution...

(Yeah yeah, I know, if I REALLY cared about the Earth I'd stop jumping out of planes for fun...mm).

Anyway, these letters into the Telegraph made me smile:

Sir - I fail to see why I should be forced to pay an extra tax on my holiday flights simply because there has been a change in solar activity.

Sir - Isn't it ludicrous to see people wearing anoraks and woolly hats in the middle of summer while protesting about global warming?
