Global Dimming Effect – UK will be like North Africa in 100 years

Anyone catch Horizon on BBC 2 last saturday about Global Dimming and the effect for 3 days after the 9/11 bombings. Less vapour trails in the sky = increased Green House effect, and the UK will be like North Africa in 100 years time, Sea level to rise 7 ft. Most interesting and a like bit worrying. 😮
