its late and i should be tired, but i am not. i expect to pay for this later on mind!
read an interesting article at some point this week, which made the sarcastic part of my mind cackle like mad. apparently the 'clean skies' policy which Europe has been following for the best part of the last 20 odd years, has contributed to global warming!!
where the massively thick 'pea-soupers' of old were full of noxious gases they were also stopping the full power of the suns rays from penetrating, now that the sky's clearer we are getting more of the suns rays and thus the earth is warming up. Gotta love the double edged sword there!
